According to the characteristics of the LED light source and different applications

(2) COB packaging,The light extraction efficiency Asus N71 Original Battery of the current semiconductor lighting source using various forms of COB packaging to improve the COB packaging is a priority, there were reports that the laptop battery second-generation (some called third-generation) matrix structure of the COB package, its luminous efficiency up to 120lm / W or above. If the total reflection of the structure of flip chip and six surface luminous body, the luminous efficiency reach 160lm / W or more.the yellow powder up to about 70% Pink and green powder, less efficient, to be further improved.Apple A1185 battery Improving the light extraction efficiency of the lamps.

(3) reduce the junction temperature,Set to 100% of the amount of light emitted when the junction temperature is 25 ° C, when the junction temperature rise to 60 ° C only 90% of the amount of light emitted by the laptop battery when increased to 140 ° C, only 70%, so the package to increase the cooling measures maintaining a low junction temperature, and maintain a high luminous efficiency.The efficiency of the LED lamps vary widely, the general LED lighting efficiency is greater than 80%, can be greater than 90%. According to the characteristics of the LED light source and different applications.

notebook battery lamps fine second optical design, but also consider the lighting heat and glare, and improve the light extraction efficiency of LED lamps.Second, hp HSTNN-OB0N battery to achieve high color rendering,White LED light and color quality content, including color temperature, color, light and color fidelity, light color and natural tones to identify the degree of visual comfort of the laptop battery [3]. SSL plan, To achieve these requirements is very difficult to do a lot of basic research, the future will be achieved. Here only discuss the urgent need to address the color temperature and color rendering. U.S.Asus N71JQ Original Battery Energy Star standards require that the interior lighting color rendering index CRI
