德彩光电户外P16全彩节能屏落户西安凤城大酒店

Dicolor P16mm energy-saving LED display obtains Xi’an Fengcheng Grand Hotel Project

    2012年6月，德彩光电户外P16全彩节能屏正式落户美丽的古都西安凤城。 

Dicolor P16 energy-saving LED display was successfully set up in the beautiful ancient capital Xi’an Fengcheng in June 2012.

德彩光电于2006年成立以来，一直致立于为用户提供满意的，高效，高品质的产品而奋斗，公司产品分别通过了德国实验室的EMC认证和欧洲EN12966认证，以及其他ISO9001：2000、CCC、CE、FCC、RoHS认证等，是一家以研发，销售为一体的高新技术企业，产品出口至130多个国家和地区。

Since the establishment in 2006, we are striving for providing out customers with high efficiency, high quality and satisfied LED displays. We are a high-tech enterprise, which specializes in R&D, manufacturing and distribution of LED displays. Our products are EMC, EN12966, ISO9001:2000, CCC, CE, FCC and RoHS approved and have been exported to more than 130 countries and areas.

    西安凤城大酒店是一家集餐饮、客房、酒吧、娱乐等诸多功能为一体的四星级旅游商务酒店，酒店地理位置优越，交通极其便利，人流量特别大，为了起到更好的宣传酒店的作用，德彩光电公司为酒店提供了一套完整的解决方案，在常规的安装方式上，采取科学的弧形设计，完美的解决了特殊地段，普通安装带来的死角问题。很好的做到了科学，人性化的设计！得到了客户的一致好评，企业不仅做好了产品，更是做好了服务！

Xi’an Fengcheng Hotel is a four-star business hotel, which provides services like catering, guest room, bar, entertainment, etc. The Hotel is located in a superior position with convenient traffic and huge population flow. In order to have a better publicity for the Hotel, Dicolor has worked out a complete solution by adopting scientific arc design on the basis of normal installation,, which settles the blind angle problem caused by special install site. On the philosophy of scientific and humanized design, we got good comments from our customers for both our products and service. 

德彩光电户外P16是一款具有高灰度等级（扫描屏达到了8192级、静态屏达到了65536级）的户外全彩屏，画面显示极其细腻，无论是在广场，大型展览场馆，演义中心观等大型户外场所观看其播放效果，都如同观看高清电影一样，画面颜色丰富，人物动作播放流畅自然。P16所采用的高亮度校正技术，还使其画面显示亮度更高。站在260㎡这样大的一款高清，高亮的屏幕面前，远远观看其画面，画质，真可与在户内高清影院观看高清电影相媲美，别有一番情趣！当然，会有人会问，这样大面积的一块高清屏岂不是一块烧钱的机器么？这下面就是要特别提到的，德彩光电这款户外全彩屏P16的一大特色了。

Dicolor P16 outdoor is with high grayscale (8192 grade for scanning screen, and 65536 grade for static screen). When watching the screen in large outdoor places like square, large exhibition venues, or live show center, the screen shows us with high richness in color, and extremely fine and delicate pictures, and has a high smoothness and naturalness when play human and animals videos. With high brightness correction technology, the screen has higher brightness. Watching in front of this 260 ㎡ big screen with far distance, it brings you a feeling of like watching a HD movie indoor by its high brightness and high definition.

However, someone might say that a screen like this large size may cost much for its electricity consuming. Don’t worry; following is one of the characteristics we would like to mention.

       选择择德彩光电就是选择高效节能，相信这就是凤城大酒店选择德彩户外全彩P16的重要原因之一。笔者替凤城酒店算了一笔帐，与传统的产品相比，德彩户外P16以每平方米每小时可以节约100W以上的电能来计算，以这次项目260㎡的户外广告屏为例，每天工作时间10小时，一年365天，那么全年可以节省电能 = （100W × 260㎡ × 10h × 365）÷ 1000 = 94900KW（度），也就是一年能节约电费达到九至十万元，真不愧称得上是一款优秀的节能产品。这下用户完全可以不用担心高昂的费用了，这一切还得益于德彩光电在节能产品研发上的付出和对终端客户的理解!

Choosing Dicolor is a choice of choosing high efficiency and energy saving product. We believe this is one of the most important factors that Fengcheng Grand Hotel chooses Dicolor. To make it more clearly, we give you the data to show the real performance of the energy saving function of P16 outdoor. Compared with the traditional products, Dicolor P16 outdoor full color saves about 100w of electricity per hour per square meter, if the screen works 10hours per day, 365 days a year, the electricity saved for the whole year will come up to  = （100W × 260㎡ × 10h × 365）÷ 1000 = 94900KW, which means the owner can save up to 90,000 to 100,000 RMB on electricity cost each year. This is a real energy saving product and users don’t need to worry about the high electricity cost any more. This accomplishment is contributed to the diligent work of Dicolor R&D members and the understanding of end-users.

       最好的产品一定是得到大多数用户肯定的产品，最好的产品一定要也需好的服务支持才能最终赢得客户的肯定，相信通过凤城大酒店户外广告屏的应用，德彩光电一定会在广大客户中积累出良好的口碑和市场美誉度！

We believe that to win the acceptance of customers, the product itself has to be the best quality, and with good after-sales service. We believe Dicolor will gain a good reputation and popularity among the customers for the installation of this Fengcheng Great Hotel P16 led screen project.

Difficulties keeping outdoor LED Display Screen cool in summer

With summer arriving we can say goodbye to the cold and dark mornings and begin to take advantage of the warmer weather by spending more time outdoors. LED Display Screen is more effective in the summer, as the weather is better and people linger longer around high streets and retail parks, taking more time walking around, increasing the dwell time on outdoor screens.
But summertime does bring with it some problems for LED Display Screen, which need consideration when installing an outdoor display. The biggest challenge with using OUTDOOR LED DISPLAY in the warmer months is the threat of overheating.
The problem with an outdoor screen is that in order to protect against the weather, the screen has to be waterproof. LED screens generate heat when in operation, if this heat isn’t transferred away, the screen can overheat and fail, but the weatherization can hamper this process.
OUTDOOR LED DISPLAY  use cooling fans to transfer, but for these to work a supply of clean air and/or vent the warm air away. Obviously, any access to the air outside could become vulnerable to water ingress. Many outdoor screen get round this problem by using intricate air chambers that allow air to pass through but not water.
Different locations, however, can experience different temperature levels during the summertime. While in some areas of North America and Europe, summers can be mild, not breaching the 30 degree centigrade mark, but in other locations, closer to the equator, temperatures can rocket to above 40 degrees and further, meaning that outdoor displays  in different locations need to be adapted for the temperatures experienced in that environment.
Some locations are just far too hot for normal cooling methods to suffice. Sometimes, locations like these require air conditioners to keep the screens cool, which can add considerably to the costs of installing and running the screens.
Another difficulty in the summer is the intensity of the sun, which not only makes a screen difficult to read—leading to high brightness screens having to be deployed—but also can add to the overheating problem, especially on the screen face if the sun is beaming directly on to it. For locations like this, a screen-cooling device is required such as an air-curtain.

Useful Ideas to Learn From Direct Sellers

Entrepreneurs can get a lot of help from the best direct selling company regarding techniques that can be used in motivating potential customers and taking control of the sales. First of all, sales people who are not properly motivated try to sell goods and services by simply giving information regarding the functions. This is definitely an ineffective way of motivating possible customers and actual buyers. In the first place, who cares about how a device functions? The real motivation comes from the benefits because it makes consumers think about positive things. It is juts natural for people to think that benefits lead to material gains so the advantages will convince them to purchase the product being offered. Aside from this, it is important to treat your customer as a friend with whom you can share ideas and provide solutions for their problems.
Value of Motivation among Sales People
Now that you know the importance of motivation in sales, you may now go on to join the best direct selling company. However, it does not mean instant success in your sales career. You also have to become a competent sales person and this will only happen if you strive to become skilled at selling techniques. There are certain strategies that can be adopted in making good proposals, sales pitches and effective closing tactics.
• Find out what the potential customer needs and special preferences. These are two different things so the key is to convince the person to like what he or she requires. If there is an indication that your client hardly cares about the item you are selling, the objective is to create the need, explain the benefits and convince that person to make the purchase.
• You have to know the thing that will motivate that individual to buy from you. Determine the priority of the family before making any sales presentation.
• Pay close attention to the feelings and reactions of people especially prospective clients. This means giving them due respect and in return, your audience will also look up to you. If these people feel disregarded, you are likely to lose one or several customers.
• Be sensitive to the time limitations of people. Do not go on talking if your listeners are in a hurry to leave. You will still get another chance to give a better presentation.
• Develop a sense of urgency to obtain a firm commitment from your prospects which means that you will have to grant some concessions such as discounts, possible rebates and extended service agreements.
• In a market, which is price-sensitive, the best salesman will emerge as winner. And the winner is the person who can prove value for the cost which means that you will have to provide built-in value for the commodity that you are selling.
• Now that you have proven the value, it is time to get ready for closing the sale, preparing for last-minute questions and moving forward. This is the point wherein you will put in order documents, contracts and other forms.

There are various techniques in sales that you can get from the best direct selling company that will help you in your selling and obtain more chances in increasing your sales and revenues.

LED display module design and realization

LED display module design and realization

With the development of socio-economic development and the information age, advertising media company is now widening the field of application of the led screen, called are everywhere. Look at mysterious color display, we doubt it plays software shall have those characteristics and related components.

You can clearly see the LED Flood Light large screen content, require a white backlight. Backlight is present in liquid crystal displays internal optical components, optical-aided by the light source and the necessary components. LED backlight if through such means as increased contrast, zone control, performance is far superior to CCFL back light source. At present, the LED backlighting has been popular in the small and medium size panel, such as mobile phones, digital photo frames and so on, with the development of LED technology and LED chip continues to mature, LED LCD TVs are likely to gradually replace the traditional CCFL LCD TV.

Backlight depending on the location of the light source is divided into lower-back light and side light type backlight. Under direct-type backlight, led strip lights source directly beneath the smooth, light emitted by a spatial distance of the light source and diffusion and mixing of diffusion plate, surface light source emitted, under direct-type backlight requires a certain amount of mixed light distance. Side light type backlight module structure of ultra thin design is more advantage, as the “thin air” up, large size thin-side light LED backlight to become the major TV manufacturers and enterprises in the upper reaches of research.

1 structure design

LED full color side light source is the design of ultra thin structure, the entire structure including: LED Spotlight bars, driven, film material, light guide plate, cooling blocks, frames, back on board. Backlight white LED light, structural design to the entire Active Area of the center point for all parts of the design center, to LCD TV with LCD screen size for the sake of design in other dimensions. Comprehensive consideration of circuit design and optical design of the requirements, to design the structure. Structure design from the u figure OUT layout ⅳ, expressed as a whole body and the relationships among the various components of the Assembly, and then proceeds to part structure design. Framework on the use of segmented design, on the length of segment, avoiding the length is too long. Lights, outlet port settings at the four corners of the back panel, winding length reduction.

2 optical design

Backlight function is by diffuse point source of light making it a surface light source. In order to be eligible for surface light source, first select the appropriate LED, this design is used in the double chip white LED. Through preset white photometric indices, on the LCD screen, optical film, and other related factors analysis of through the back on the calculation of the required luminous flux of the light source. According to the calculations of luminous flux, combined with the LED optical properties of number of the calculates the required LED. As shown in table 1 for selected LED electrical and optical.

In order to increase the brightness of the backlight, match for membrane structures: a diffusion sheet + one BEF+ of a DBEF. Where diffusion is to take the role of diffusion material refraction and reflection of light spray, injection of more uniform: light BEF’s role is to gather, make it vertical into the LCD module to improve luminance: DBEF was originally absorbed by traditional absorption-type polarizer using 50% to increase the brightness of light. Lightguide plate dot diameter 0.54~1.55mm. Figure 1 shows the Lightguide plate part of the network map.

3 circuit design

Light source with dual-chip white LED light, led backlight for distribution in four weeks. In order to achieve a better current uniformity, lamp and hybrid, two and more. In order to achieve better heat dissipation, LED lights with aluminum plate processing. Input voltage of 24V the system as a whole, this voltage is provided by external power supply converter.

3.2 design of drive control circuit

Driver IC is a triple peak current-mode PWM controller, through closed-loop controls the output provides high-precision LED current. The chip contains three peak current mode controllers, provide feedback to IC to ensure high efficiency and high precision. Gate drives are optimized on the chip, used to drive the 0.25A source or O.5A sink current logic level FET, each output current can be linear or PWM dimming for a separate dimmer.
3.3 thermal design

Because the LED luminous efficiency is low, will produce a lot of heat while you work, without addressing the thermal problem, will led to attenuation and shortening of service life of LED light brightness. In order to curb the heat impact of LED backlight luminance and chrominance, thermal design of the LED.

The led display the stand or fall of fire protection technology mainly and led display screen of raw material, the technology of fire prevention has great relevance. Experts point out that fire prevention raw materials mainly include the use of internal display of wire rod, the power supply, the external protection structure fire materials and plastic package these four aspects:

One, in the most of the led screen display applications, the led sign display unit of area, the greater the show, its power consumption, the greater the stability of power wire has higher requirements.

Two, at the led display external protection structure material, the market level higher screen fire products are mostly using fire prevention aluminum-plastic plate, the watery excellent resistance, fire retardant sex is extremely strong, core material special material oxygen aging performance is very strong also, and outdoor led display products of aluminum-plastic plate with high temperature, rain cold and hot shock aging faster, so that in the humid climate season section, dew or rain can seep into the screen body internal cause electronic components short circuit of fire.

Three, through the UL authentication of the power supply products is also choose the best choice of similar products, the effective conversion can ensure that the power supply load security and stability, in the external environment temperature hot case, also can work normally.

Four, the led display fire prevention raw materials and an important part, that is plastic package. Role is to not only has the flame retardant function, can be in more in high temperature and use for a long time, not deformation, not become brittle cracking, and combining with the sealing good glue use, can effectively prevents the external environment of rain through into internal cause a short circuit fires.

Of course appeal mainly from internal raw materials at four o 'clock for, but the external configuration and design also is very important. Mainly involves the heat to fire, in led display work will deploy platoon fan and air conditioning in the led screen body internal cooling cooling, sometimes air conditioning or platoon fan configuration is not in place will cause the heat processing is not even, easy to cause the due to the temperature ascending and cause screen body internal security hidden danger. While many of the enterprise in the protection grade test, just simple simulated in the external environment spray waterproof test, waterproof, durability and strength to effect on textual research. Led products used after period of time there will be porous to happen. This is also causes the outdoor led display fire or use the important reason for the short life.

In telling the led sign display in technology and can't careless, must carefully serious to find, analysis, finally solve the problem. Technology involved in the aspects is very wide, so want to be many reasons to observe, above, and what we are internal factors, of course, also cannot ignore late in the process of maintaining man-made factors. So to do the led display industry leader, must be in technology on hold, by the high quality, YanGuiGe for themselves to guide the healthy development of industry, to promote the industry in the international competitiveness, toward internationalization

Anlaysis of fire accident caused by LED display

[Common sense]Today, LED display are mainly divided into: full color display series,  EMC display series, rental display series, traffic guidance screen series, energy-saving display series, stadium display series, customized series.

With the rapid development of internet information technology, advertising media are having more attention of the society gradually. Because of LED display’s high brightness, low working voltage, low power consumption, large scale, long lifespan, varieties and other characteristics, are widely used in stadiums, city and public square, traffic, enterprise image promotion, business advertising and other applications.

In the vigorous development of LED display industry today, incidents frequently caused by LED display have caught the wide attention of the society.

Fire accident review:

In September 24th, 2011, a big LED screen collapsed from the stage of Wenzhou Shangri-La Grand Hotel.

In September 24th, 2011, a main LED screen of Guangzhou new library, which faces the Flower city square, suddenly went on fire.

In December 16th, 2011, a LED screen at Cade shopping centre on Xi zhi men Plaza went on fire.

In December 29th, 2011, a LED screen on Yue qing City Traffic Building in Zhejiang Province Went on fire suddenly.

In April 23rd, 2012, a LED screen on top of the Harbour Grand Hotels in Hong Kong went on fire.

Fire accident analysis:

As a kind of new environment friendly and energy-saving high-tech green product, LED Display is very popular and has become cities’ indoor and outdoor advertising’s highlights with its superior visual sensory properties. So what are the factors that lead to a fire incident, above all, display manufacturers and owners should bear the corresponding liability.

Product’s bad quality, the effect of external environment and the mistake of manual operation, are the causes of fire. Secondly, when owners purchase products, low price is often placed in the first place, and neglect the quality of products. This makes some manufacturer have to cut the purchasing cost to save the production cost in order to meet the customers’ requirement on low price, thus left a risk of fire happening.

Fire technique analysis:

To analyze from the professional perspective, Dicolor optoelectronics think that the main factors that caused the fire are the following:

1. Improper use of power supply switch. Manufacturers don’t use the right power supply switch that can meet the actual required rated power switching power supply. When the actual load exceeds the rated power of the switch, power supply switch load is too large, thus resulting in power supply switch burnt out and cause fire of the LED screen.

2. Use of unqualified outer protective structure material on the LED screen. The protective structure material’s fire resistance, fire retardant, aging resistance does not meet safety standards.

3. Cabinets wiring. Cabinets wiring does not meet the standard requirement, does not meet the wiring principle, and leave hidden safety problems.

4. Power supply wiring. Distribution of power supply between modules is not balanced in DC power supply system. Distribution of power supply is not balanced in AC power supply system. These are the potential causes of the fire.

5. LED lamp selections. Always focusing on the requirement of the high brightness of the LED screen, leads to the aging of materials, and then reduces the lifespan of screen, thus caused the materials on fire.

Note: When Dicolor Optoelectronics chooses the LED lamp, we keep a balance of 20%, so as to reduce the current of module made under this design. (Current of P16 static module is around 7~8A, average current of video is about 2~3A), products are made with high stability, high efficiency, and energy saving.

6. LED brightness ratio: When some manufacturers choose the LED RGB color selection, they do not follow the principle of 3:6:1. Many manufacturers use small size LED chip in order to reduce the procurement cost of raw materials. This lead to the improvement of LED current for each single module in order to reach the white balance, and this will no doubt increase the temperature of some part of module. When part of module temperature is rising, and there is no good solution to dissipate heat, the module will show result of inconsistent brightness, and will finally cause fire as the aging of materials after long-time use.

7. Kit. Kit materials do not reach the fire retardant standard listed under<UL94V0>.

8. Glue Dispensing. Glue does not meet the standard fire retardant requirement listed under <UL E325549 V0>.

9. Wire. Wire is not selected according to National Standard. Wire wrapping material does not pass standard fire retardant requirement of <IEC 60332>.

Note: The wire core size chosen by Dicolor Optoelectronics is decided by a strict calculation at the beginning of design. To meet the practical needs, meanwhile keep sufficient margin in actual use.

10. Key components. When used for a long time, the temperature of key components can not be maintained at a reasonable level.

Matters needed to be noticed during installation and use:

1. During the installation process, LED screen body and the connecting part between LED screen body and building must be strictly leak-proof and waterproof;

2. The reasonable installation of ventilation equipment for cooling. So as to keep the screen body at a temperature of -10℃ ~ 40 ℃. Use axial flow fan behind the screen body at the top to dissipate heat.

3. The correct installation of lightning protection device. Make sure the LED display screen main body and the building enclosure grounded to earth. Thus to let go the large current caused by lightning.

4. The fault wiring of power supply wire during installation. For example, three-phase electric mix, zero and fire wire mix, strong electric directly connected to the weak electric.

5. Strictly follow the LED display using instruction. Such as first boot the IPC, and then switch on the screen; first close the screen, and then shutdown the IPC.

6. Avoid switching on the LED screen under white balance or screen out of control. Because the system impact current is at the highest point under these condition.

7. Make sure to have professionals to check and maintain the LED display regularly.
