Philips Lumileds: Development Roadmap for LED Products Driven by Different Applications

At the China International LED Application Forum on February 19, Mr. Alvin Tse, Vice President of Asia Pacific Sales of Lumileds, made a report on “The Current Status and Future Trends of Traditional Lighting and LED Lighting Markets”. In the report, he pointed out that the era in which a size LED is used in all fields has become history, and in the future, it is necessary to produce a series of products to meet a wide range of market applications. Lm/W, lm/$ and continuous improvement of lighting quality are the main driving forces for the future development of LED. He carefully analyzed the development road maps of different types of lamps Lm/W, lm/$ (shown below).

Figure 1 The development road map of different types of lamps Lm/W, lm/$ Albin also described their five definitions of "good LEDs":

1. Quality of light. include:

a. CRI> 80, and give positive consideration to R9, CQS, GAI;

b. Consistency of light within the beam angle range <10 U'V' points;

c. LED lighting operating temperature of 55-85 degrees, using 85 degrees as the detection temperature, the so-called "hot test"; thermal testing can eliminate many unknowns for customers, simplify the design process, reduce system development time, reduce the final design The importance of testing, reducing costs, etc. is evident;

d. to maintain the consistency of the color, within the scope of the human eye recognition, that is <3 SDCM;

e. The color will drift over time, the range needs <5 SDCM;

2. Fixed sales, application (freedom from binning).

Since last year, for the convenience of customers, the chips sold by Philips have begun to be set. For example, customers need chips of 2700K, and they can buy chips of 2700K all from Philips.

3. Packaging flexibility;

4. Integrated optical control;

5. Driver compatibility.

Philips currently concentrates on the first two tasks. He believes that in terms of light quality and reliability, LEDs can give users additional added value and traditional lighting cannot be realized.

Alvin also introduced that as early as 1961, Philips entered the LED field and provided services to printers and other manufacturers; in 2007, Philips focused on the backlight and automotive applications, but the emphasis on LED lighting began to increase substantially in recent years. . In 2009, it began to return to the lighting field. At present, the company attaches great importance to the research and development of the LED field. 90% of the lighting research and development costs are spent on LEDs. However, Alvin believes that the speed of LED replacement for energy-saving lamps will not be particularly fast. He believes that Lm/W or lm/$ and lighting quality will become the two major driving forces in the future. It is estimated that the penetration rate of LED lighting in 2015 may reach 45%. 46 billion euros.
