LED light source chip LCD projector market bottleneck

, a cost problem

The cost relates to the final product pricing and marketing definition, is the most important problem in the case of Q5, a market price of up to 5 dollars, while a machine needs a lot of pieces, such as a 17 LED projector, the production process to ensure that at least 20 pieces the production and testing of loss, resulting in a large area of the chip is damaged even in welding and fixing are possible; light distribution system cost is not low, light is put into this kind of precision mould pure hardware, the number is very considerable, and glass materials, wire, conductive materials, all dependent on imports, in the early stage of development. Optical engine internal wire selection of all electrical gold coating materials; meet the aspheric lens projector standard, the rate of finished products is not high.

But we can be pleased to see that the LED and related industries, are seriously and pay close attention to the development of the projector industry, a year ago, LED industry ranked first several first tier manufacturers, and almost no projector manufacturers cooperation intention, but now there is a very big change, each other through continuous exchanges and in-depth understand, in addition to second-line LED manufacturers, first manufacturers have shown more enthusiasm, including Nichia Corporation (Nichia), TOYOTA (TOYOTA) it never asked the projector industry manufacturers, also began to focus on them, possible ways of cooperation is more diverse, cooperative efforts are increasing daily, believe through the horizontal LED extensive exchanges and related industries, the cost will not issue.

The best way to solve the problem of cost, should be the time, the development of LED industry too fast, we don't need the most sophisticated LED chip, we only need to meet the design specification document LED projector products, of course, this day will come soon.

Two. Market orientation

Whether customers or terminal, the advantages of LED is realized in a short period of time, and the 150W metal halide lamp models of the price gap is very direct, although it is used LED light projector is better than the traditional light quality, but has a very mature metal halide lamp than light projector again, and their price gap is not proportional, so in addition to chuangrong and Ruicheng to explore in the field of LED, the other to enter the field of manufacturers, is still wait-and-see attitude more.

In a long term and a is what experience has been compared to the value, consumers choose the kind, is correct, we can not deliberately require consumers to choose advanced technology and lasting value LED projector, we do not strongly support consumer choice of traditional technology of 150W metal halide lamp projector, choose what consumers say the count, and what we should do, let the market decide, and innovation must be done, is the ability to achieve mass production of LED light projector.

Three, heat problem

LED light projector, in addition to the cost can not reflect domestic projector cost-effective advantages, cooling technology is also difficult to find the balance point to solve things, not the cooling solution is not good, but to solve the problem of who pays, of course, can also be grouped into cost.

LED light source heat dissipation, a fan of the traditional technology has been inadequate, LED is cold light, is not to say that LED does not heat at work, not only refers to the spectrum with infrared and ultraviolet fully, do not allow high temperature is one of the inherent characteristics of it, for now, LED's energy efficiency is not high, although the light the efficiency is very high, there is considerable heat emission from the chip, but also must have derived in many degrees celsius.

Of course, with the continuous investment in scientific research, these issues will not be a problem, I believe in the future, LED projectors will have broad prospects.
