P3 LED Module Production line:
2018 LONGRUN hot sale P3 indoor led display module
| Q: What is the brightness, viewing angle, and wavelength of the LED? |
A: Luminous Intensity is equal to the amount of luminous flux
emitted into a very small solid angle at a defined angular
orientation from the light source. The measurement for luminous
intensity is the candela. The symbol is Iv.
|
| Q: What is the dominant wavelength? Please specify the ranges of wavelength in red, green, and blue colors respectively. |
A: Dominant wavelength is defined as the best range of wavelength showing the most natural color recognized by human eyes. Researches indicate that fixed colors with a wavelength of 620-630nm (red), 520-530nm (green), and 460-470nm (blue), in fact, mixed in a particular proportion, can get the pure white. That is, in the display field, people use luminous materials with the above wavelength to make "compounded" white more natural. In order to get a good balance white led display, we specify the led colors with wavelength within 4nm for each color
|
| Q: Which chip vendors are you buying from? |
A: It depends on the Customer's requirement. We can purchase from Japan, Korea, Europe, USA. We are using chips mainly from Taiwan
|
| Q: What is the chip size you're using for outdoor display? How about an indoor display? |
A: For outdoor display, we're using a 12mil chip for red, 14mil for both green and blue. Regarding indoor display, 9mil for red, 12mil for green and blue are currently adopted
|
| Q: How much will the brightness of LED drop down after 1000hrs? |
A: Based on the result of the aging test, the brightness decay of green LED is around 5%-8%, while blue is around 10%-14% and red is around 5%-8%
