The coefficient of heat and cold (ie, the ratio of the LED output at 100 ° C junction temperature and 25 ° C junction temperature) is the specification value in the LED data sheet. The LEDs in the lighting device operate at very high junction temperatures, typically between 80 ° C and 110 ° C. As the temperature rises, the light output and energy efficiency decrease. When the junction temperature is 100 ° C, the typical coefficient of thermal coefficient is .80 -.85. It is critical that companies improve this factor as much as possible when designing ENERGY STAR-compliant solid-state lighting solutions. Philips Lumileds' new LUXEON Reb el LED has a thermal coefficient of .93 that provides higher light output and performance than almost any other power LED.
RudiHechfellner, head of technology solutions at Philips Lumileds, said: "The coefficient of thermal and thermal resistance is one of the obvious differences between LEDs. The high coefficient of thermal insulation helps simplify the design of the heat sink system and reduces the cost per lumen in the final application."
2 In 1 Laptop
Do you know the difference of Yoga Laptop and 2 in 1 laptop? No. 1 is yoga notebook with 360 flip rotating absolutely; No.2 is laptop yoga slim is just like normal Education Laptop-connecting screen with keyboard, but 2 in 1 laptop tablet with pen is separately, you can use the monitor part as a window tablet. In one word, every intel yoga laptop have all the features and function of tablet 2 in 1 laptop except separated screen and keyboard. From the cost, windows yoga laptop is much higher than 2 in 1 type., cause usually former with more complicated craft and quality.
What other products you mainly produce? It`s education laptop, Gaming Laptop, engineering laptop, Android Tablet, Mini PC and All In One PC. You can see more than 5 different designs on each series, believe always have right one meet your special application or your clients demands. Therefore, what you need to do is just to get all the requirement details from your clients, then share the complete information with us, then we can provide the most suitable situation.
Of course, you can also call or email or send inquiry of what you need, thus can get value information much quickly.
