Smect Zhang Luhua: PCT/EMC has its own king, choose the right product according to needs

"When I got this topic, I was very entangled." At the 2016 Gaogong LED Annual Meeting, the "Outdoor Lighting New Opportunity" special titled by Xu Yu Optoelectronics, Smale Marketing Director Zhang Luhua said that the current mainstream on the market A large number of brackets, 2835 is definitely the mainstream thing. 2835 has PPA and PCT, and has EMC, which is represented by 3030.

These two, which one is the king, think a lot.

     The same is the PCT bracket. Is it the same for everyone? Is there some level of jagged, good, and bad, also the EMC bracket, the level we have made is actually different, there will be some differences, the field and the market are different. If you want to separate the two from one king, I think there are different kings and how to use them.

     What is the king of the two?

EMC products

     From the global situation, the overall volume is declining. The amount of EMC in China is increasing. The volume of EMC in the world is decreasing. Why is it reduced?

     This is related to the rise of domestic EMC companies. At present, full power coverage of less than 25 watts has been achieved, with products in every segment. Of course, the usage is not the same. There is a part that overlaps with the PCT bracket and the purpose is different. 5050 is basically 3-7 watts, 3030 is 1-3 watts, there are indoor products, there are outdoor products.

  EMC for indoor lighting

     The share of EMC's products in indoor lighting is actually declining, stemming from the maturity of the PCT bracket.

     In many areas, EMC brackets are no longer needed, and PCT brackets account for a large portion of indoor lighting. The specifications of 0.5 watts or more can be used with PCT brackets, which are basically used. Bulbs are used. EMC mainstream is still on high-power products. Other products, such as candle lights, have a wide range of EMC applications, and their share of panel lights is increasing.

     EMC for outdoor lighting

     EMC products in outdoor lighting products are rising, and have their own characteristics, and their own heat resistance. What is the integration of COB, is it increasing or decreasing in the outdoor? The answer is falling.

     It has fallen, and which shares are increasing? In fact, in outdoor lighting, especially in street lighting, EMC products are increasing. Among the outdoor street lights, the 3030 specification, and even the 5050 and 7070 specifications are increasing rapidly, which has a certain relationship with itself.

    Outdoor lighting application for EMC3030 module

     Outdoor street lights, with the solution of optical lens problems, including floodlights and floodlights, are suitable for 3030 and some for 5050. These two specifications are used in outdoor.

     Through the so-called high-power method, it ultimately depends on whether the reliability can be met, the cost performance has no advantage, and the lowest performance can be achieved if the same performance is achieved.

     The current status of light efficiency of Simai high-power products

     Some of our high-efficiency products, 5050 products, now have a lot of light efficiency, 1-5 watts universal, can be used in 5 watts, single light efficiency to 160lm / w, 3 watts to 180, 2 The tile is 195, 1 watt to 220, and the current level is 240 lm/w. It is a good choice among outdoor street lights.

    PCT

     The PCT that everyone does, and even the PCT that everyone uses, is different. PCT2835, at a very high temperature of 110 degrees, must have sulfur-containing rust, which is reflected by the silver-plated layer, forming silver sulfide, causing the lamp beads to attenuate very much.

     Our product is not vulcanized at a high temperature of 128 degrees, but it will decay at such high temperatures. This has a certain relationship with the attenuation of PCT glue, we can use EMC stuff, it will be better. It is comparable to the EMC3030 and is definitely not expensive.

     Vulcanization experiment: mainstream PCT products on the market, including international brand PCT products, under the same conditions, 34G sulfur powder is tiled in 800ml glass bowl, lamp beads are attached to the bowl lid, sealed, placed in temperature setting Heating in a 85 degree oven for 4 hours with substantially no attenuation.

     Therefore, the PCT is not the same as the PCT, depending on the choice to use.

     EMC and PCT, you can choose according to your own situation. Outdoors, I personally recommend that you use EMC products, the glue is PCT, its heat resistance is still worse than EMC products. If you go to the stability of the UV and outdoor harsh environment, EMC is still better.

     If you want to talk about it, the product of PPA within 0.5 watts is enough. In the normal case of 0.5-1 watt, everyone chooses the conventional PCT; if the temperature is particularly high, you can choose AK35, which is also a bracket of 2835; the higher the temperature, everyone Just choose EMC products.

     In terms of global conditions, domestic packaging plant capacity continued to expand, and Smax had doubled EMC's packaging capacity in the first quarter of 2017.

     In 2016, there were more patent litigations than ever before. Everyone's protection of intellectual property rights became more and more stringent. For patents, we have done a lot of work with the entire group to solve the problem of global patents, including white light patents.

     Finally, Zhang Luhua gave his opinion on the theme of the speech in one sentence: each has its own king, according to your own choice, choose the right product according to your needs, and get the best value at the lowest cost.
