LED industry production scale expansion of creativity is the key to sustainable development

Use past is a mobile phone, LCD TV recently, people are always a hot topic in LED, and the market of large scale new uses are emerging. Now, the companies are trying to seize the huge market lighting. LED vendors will be how to develop new uses?

LED has gradually ushered in the popularity stage

OSRAM, President of semiconductor, said AldoKamper lighting can be said to have just begun. Prior to the regular use of LED lighting, most of which are special purpose lighting and street lamps, these lamps in the lighting market is only a very small part. In the future, LED will gradually penetrate into the home lighting market as the protagonist.

LED as the protagonist of the use of frequent conversion. The reason is that although the LED in the process of replacing the existing light source LED market continues to expand, but with the replacement rate gradually approaching 100%, LED market began to shrink. LED backlight is a typical example. LCD panel backlight LED will reach 100% in the near future. Now, LCD TV with LED backlight process is rapidly advancing, but 2 to 3 years after the adoption rate will reach 100%, the estimated future LCD TV market will shrink LED.

This is why, according to AldoKamper, because the LED technology is in the development stage, the luminous efficiency is steadily improving. The higher the efficiency, the fewer the number of LED chips used in the backlight source. Moreover, the LED chip price will continue to decline. Mobile phone LCD backlight LED also exist in this case.

In contrast, the family of ordinary lighting with the LED market will continue to expand in a longer period of time. LED lighting unique advantages will be well received, the entire lighting market is expected to further expand.

Different LED lamps for consumer preferences

Previous lighting with LED pay more attention to luminous efficiency and cost. But taking into account the promotion to ordinary lighting, the future "QualityofLight" (the quality of light) will become more and more important. Especially in Europe, consumer demand for higher quality. General lighting, European consumers prefer halogen lamp, bulb type fluorescent lamp (CFL) is not popular. This is because the CFL quality is not high. The luminous part of the halogen lamp is bright, and the color (CRI) is high. The CFL brightness is not enough, CRI lower than halogen lamps.

For color temperature, different areas of consumer preferences are different. In Europe, the low temperature lamps will receive a lot of orders, and in addition to Japan in Asia, people generally prefer a higher color temperature products.

To meet consumer demand for a variety of lighting lighting, LED manufacturers need to use a variety of CRI and color temperature, and can improve the efficiency of light-emitting technology. This is our future goal.

As long as the creativity, LED will continue to develop

AldoKamper said it is unclear the next promising LED market. He said that in the LED industry, it is very difficult to predict the situation a few years later. Such as LED projector. 6 ~ 7 years ago, due to too little light, projector light source can not use LED. But now it's done.

The same is true of the LED headlights. 6 ~ 7 years ago, LED encountered insurmountable obstacles, brightness has not been able to reach the level of light can be applied to. From the cost, the LED headlamp is also difficult to achieve. And now, LED not only improve the performance, the cost can be reduced, and even with the HID headlight competition.

AldoKamper said OSRAM was also surprised by the development of LED. AldoKamper believes that as long as there is creativity, LED will continue to develop, the market will continue to expand, look forward to LED can generate new uses.

AldoKamper said that enterprises to develop new applications, there are two key points. One is to work with customers. Learn new applications from customers. In order to achieve these purposes, we will think about the problems and solutions of LED, and continuously develop LED.

The other is our prophetic ability. To introduce the company's leading technology is being developed, please recommend new customers. We will promote the development of LED technology at the same time, strengthen communication with customers, and strive to put forward new ideas.

Familiar with the customer of the equipment and familiar with the technology of our own ideas, which is conducive to improve creativity, and then find new uses.

LED industry to expand the scale of production trends

From the increasing demand for LED and low cost requirements, it is clear that the need to improve LED production capacity. AldoKamper said that OSRAM will actively enhance production capacity, based in Malaysia, Penang (Penang) LED production base has doubled the size of the LED chip production.

At the same time, OSRAM will also focus on improving manufacturing processes, expand production scale and reduce costs. For example, will promote the use of sapphire substrate manufacturing large aperture. OSRAM from 6 years ago began to use LED chips when the substrate diameter increased from 2 inches to 4 inches. By this method, the production efficiency is greatly improved. OSRAM is currently considering to increase it from 4 inches to 6 inches.

Large diameter is an important means to improve production efficiency. For example, no need to increase the number of MOCVD devices used to form the semiconductor light-emitting layer, such as LED, can significantly increase the output of LED chips, improve the cost competitiveness. We will increase production capacity by expanding production lines, promoting large diameter and increasing yield.

Silicon substrate is currently advancing 8 inches
