As growing demand for the LED lighting, LED factory for the maximum benefit from the market, have to strike a balance from the technical development and control the cost, so the development direction of GeChang focus Yu Guangxiao than from the past (lm/W), and then extends to the ratio of (lm / $) (us $), if in accordance with the U.S. department of energy (doe) is put forward in 2011, 1000 lm / $2020 target, philips is to put 2000 lm / $2020 goal.
In 2011, the U.S. department of energy (doe), solid-state lighting development plan shows 2012 warm white and cold white light luminous efficacy is respectively 141 lm/W and 176 lm/W, and LED components ratio are respectively 133.33 lm / $and lm / $166.67; Expected 2020 warm white and cold white light luminous efficacy will reach 253 lm/W and 258 lm/W, and the LED component ratio is 1000 lm / $.
With LED chip packaging technology constantly improve, philips solid-state lighting (SSL) expert George Craford argues that in the next 10 years technology will increase the lm/W along with the development of lm / $2013 market warm white and cold white light luminous efficiency has reached 129 lm/W and 164 lm/W, and the price is 196.08 and lm / $and lm / $250, estimates the market in 2020 will reach 224 lm/W luminous efficiency and 235 lm/W, and cost-effective for lm / $1429.
Philips is set higher development goals, George Craford, said philips goal in 2020 cold white and warm white to synchronize 266 lm/W, and expected to do 2000 lm / $.
