[Annual Meeting] Liyang Optoelectronics Qu Junyi: Outdoor lighting points to low color temperature, high luminous efficiency and low cost

[Text|High-tech LED reporter Xu Chaopeng] "In 2015, the market price of LED lighting fixtures may drop to 1/3 of 2010, when the penetration rate of LED will rise to 50%, it is predicted that by 2020, LED lighting It is very likely to occupy more than 75% of the market share.” Li Junyi, general manager of Liyang Optoelectronics, said at the 2014 High-tech LED Annual Meeting, which was named by Mulinsen’s “New LED for the Next Three Years” theme.

However, in the LED industry, compared with the indoor lighting market penetration rate, the market growth rate of outdoor street lighting is still relatively slow, and its main application areas are still concentrated in economically developed areas such as the Pearl River Delta, while many cities in China still stay in Investment in the market, or the stage of demonstration applications.

"The reasons for this, the policy level and the interest-driven level account for a part, but more should still analyze the technical level issues, color temperature and light efficiency and cost price factors are the main reasons restricting the slow development of LED outdoor lighting." Qu Junyi said .

It is understood that the current shortcomings of outdoor lighting street lamps are: 1, the color temperature is too high, so the penetration ability is weak, and affects the sensitivity of the sensor; 2, low light efficiency, from a safety point of view, the government department does not recommend; 3 The cost is high, and there is usually a phenomenon of saving electricity and not saving money. Even if it is a contract energy management method, the recovery cost is too long.

"Therefore, the future development trend of outdoor street lights will focus on the development direction of low color temperature, high light efficiency and low cost." Qu Junyi said.

It is understood that currently Liyang Optoelectronics should launch a combined solution for this problem: low cost + high luminous efficiency + low color temperature, its street lamp module color temperature CCT = 2850K, light efficiency up to 150 LM / W, while the cost is more than the industry products to save 20 %-30%.

"Using the module of Liyang Optoelectronics, after assembling the whole lamp, the whole lamp cost is about 6 yuan / watt, the direct cost is 1400 yuan. The 140 watt replaces the 450 watt whole lamp, the luminous efficiency is unchanged, and the electricity saving for 8 years is :0.8 x (0.45-0.14) x 10 x 365 x 8=7241.6 yuan, the economic account space is very large." Qu Junyi calculated.

Electronic design is also trying to reduce its size while continuously improving the performance of the whole machine. From mobile phones to smart small portable products, small is always the same pursuit. High-density integration (HDI) technology enables end-product design to be more compact while meeting higher standards of electronic performance and efficiency. HDI is currently widely used in mobile phones, digital (camera) cameras, MP3, MP4, notebook computers, automotive electronics and other digital products, among which mobile phones are the most widely used. HDI boards are generally manufactured using a build-up method. The more times the layers are stacked, the higher the technical grade of the board. Ordinary HDI boards are basically one-time laminate, high-order HDI uses two or more layers of technology, and adopts advanced PCB technology such as stacking holes, plating holes, and laser direct drilling. High-end HDI boards are mainly used in 3G mobile phones, advanced digital video cameras, IC carrier boards, etc.
