Philips Lumileds: high performance is more important than low cost

The overall lighting market presents a 'downward Competition' situation. "Sponsored by LEDinside, LED and Chinese Guangzhou International Lighting Exhibition LEDforum 2014 Chinese international LED market trends Forum, Philips Lumileds market and business development senior director Ray Chock mentioned in his speech. Of course, the downward competition here is aimed at the decline in prices. From 2010 to 2014, the retail price of PHILPS LED bulb has undergone tremendous changes. When the LED bulb went on sale in 2010, the retail price was $49, when the price was low, and consumers did not intend to accept expensive LED bulbs. Over the past few years, the price of the LED bulb lamp fell significantly, by 2014, people can buy a PHILPS SlimStyle LED bulb with a price as low as $5.

Ray Chock said: with the rise in market penetration, low price competition has become the key to the success of the LED industry. Perhaps one day, the price of LED bulbs will be as low as $2.5, then, LED lights and CFL lights will be more intense competition between. However, manufacturers are too concerned about the cost, so as to ignore the quality and performance. "

Ray Chock said that many people began to consider lm/$, but the price of LED lamps are not entirely dependent on the cost of LED. According to the analysis of Philips Lumileds, high performance is more important than low cost, high performance may reduce the number of LED use. "Manufacturers can reduce the number of LED use, or reduce the size, so that the size of the heat sink can be smaller. "

Ray Chock says most of the heat sinks are made of aluminum with a higher cost. The cost of LED is only about 20%-25% of the total cost of the lamp, so it reduces the influence of reducing the total cost. Thus, LED system design becomes more important than the LED itself. Ray Chock stressed: LED is important, but the system design is the key. The overall system stability is the weakest link. "Although the LED supplier can determine the reliability of LED, but other parts of the LED system is not broken, also need to be guaranteed.

In addition, Ray Chock believes that the design of a complete LED, the factors to be considered should include the cost, light efficiency, reliability, light quality, lamp shape and color adjustability. In addition to the previous emphasis on LED reliability, the quality of light is another problem Philips Lumileds attention. Ray Chock, color temperature change, angle color, color rendering and uniformity of light are important parameters to test the quality of light. In addition, the influence of the light source size on the quality of the light is also very large.

Today, the market price of LED bulbs emerge. In this regard, Ray Chock said that in the face of many low-cost LED bulbs, consumers in the choice of products will no longer just pay attention to the price. Compared with the low light but poor performance, consumers will be more willing to buy expensive products with high luminous efficiency. LED manufacturers should see things outside the U.S. dollars per dollar, in addition to reducing costs, LED manufacturers should look for other ways to maintain a favorable competitive position, to prevent being eliminated by the market.

And a new technology from the proposed to be adopted by most consumers, and then to be replaced by other technologies, known as the use of technology life cycle. Technology adoption life cycle as a bell curve, the curve of consumers will adopt new technology process is divided into five stages: innovators, early adopters, early and late mass mass and backward, the proportion is respectively 2.5%, 13.5%, 34%, 34% and 16%.

Ray Chock uses this curve to show the adoption cycle of solid state lighting technology. With the technology adoption life cycle, the solid-state lighting cycle is divided into five stages: early adopters, lamp replacement, innovative light experience and appearance, daily necessities and alternative technologies, represents the rise and decline of future solid-state lighting.

Ray Chock said that in 2014, solid-state lighting market is in the early stages of innovative lighting experience and appearance. With the improvement of life quality, people on the lighting requirements no longer stay in the "bright enough", but more relighting experience, aesthetic appearance and intelligent setting etc.. In terms of architectural lighting, the lighting requirements have been divorced from the traditional concept of lighting, pay more attention to color adjustability, color stability and color changes with the angle. For example Guangzhou waistline, it adopts more than 6 thousand sets of PHILPS LED lamps, with a perfect combination of LED ColorReach Powercore high power dynamic color floodlights and Dynaflood LED professional dynamic floodlights, use colors to highlight its architectural structure, bring people a visual feast. Here, the pursuit of high efficiency market is not so important, building lighting has from functional lighting into the pursuit of artistic beauty. (text /LEDinside Flora Leah)
