Lumileds talk about the development trend of LED lighting

[LED] as the Moore law of the semiconductor industry, LED industry has a Haitz law. According to Haitz's law, LED brightness can be doubled every months, in the next 10 years, is expected to be able to enhance the luminous flux of 20 times, and the cost will be reduced to the existing 1/10.

From 1965 to 2002, this trend has not changed. We can boldly predict that by the end of 2015, the cost per lumen will be as low as 0.25 cents. At present, the cost per lumen on the market has been less than 1 cents, about between 0.25 cents to 0.33 cents. In the LEDinside, China LED network and the Guangzhou International Lighting Exhibition hosted by LEDforum 2015 China International LED market trends Summit Forum, Lumileds Ray, senior director of marketing and business development, said Chock.

LED packaging, the industry began in 2005 to try COB packaging, and now COB single product is a luminous body can reach 2000lm, a number of high-end COB products can be a luminous body 10000lm. In a sense, COB products win the Haitz law. The emergence of flip chip, but also to further reduce the size of the package and reduce costs, thus reducing the cost of LED lamps. This is also a reflection of Haitz's law, the cost continues to decrease, and the performance of continuous improvement.

Ray Chock said that we not only look at the evolution of LED from the technical level, but also to focus on the development of the industry. At present, the price of the LED bulb has fallen below $5 mark, as cheap as an energy-saving lamp or even an incandescent lamp. LED's current price is only five years ago, the decline rate of 1/10 is quite alarming.

In addition to the price, LED in the shape of the design and function also has a significant change. Ray Chock said that in 2013, LED bulb began to appear, this shape on the one hand contribute to heat dissipation, on the other hand, in order to cater to consumer preferences. With the promotion of technology, a variety of dimming color, intelligent control and other additional features are emerging. LED industry is not only to provide lighting, more innovative applications, the future of LED lighting will be moving towards the direction of art.

This is also evident in the development process of automotive lighting. The development of automotive lighting is divided into three stages: the first stage is to simply replace the incandescent lamp; the second stage with some process design, car LED began to have a variety of eye-catching appearance; the third stage, LED began as a spare light source or turn to the lamp, it is really a new development trend, and even become the application of car decoration the.

Ray Chock added at the end of the speech: "there is one thing that should be noted is that disruptive Internet of things technology. Currently, there are 15 billion things connected to the object, by 2020 this figure will reach 200 billion. This also means that by 2020 a person may use 26 'smart objects', which is a considerable part of the relevant lighting products. Digital lighting innovation, but also led to changes in people's daily lighting needs, the future of LED lighting will be very artistic. "
