FAQ
| 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. Symbol is Iv. Viewing Angle is the total cone angle in degrees encompassing the
central, high luminous intensity portion of the LED beam from the
on-axis peak to the off-axis point where the LED intensity is 50%
of the on-axis intensity. This off-axis point is known as theta
one-half ( 1/2). Two times 1/2 is the LEDs' full viewing angle;
however, light is visible beyond the1/2 point. Wavelength is the distance between two points of corresponding
phase and is equal to waveform velocity divided by frequency. It
defines what color human eyes could recognize |
| Q: What is dominant wavelength? Please specify the ranges of
wavelength in red, green and blue color 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 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 display
field, people use luminous materials with 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 indoor display? |
| A: For outdoor display, we're using 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 aging test, the brightness decay of green
LED is around 5%-8%, while blue is around 10%-14% and red is around
5%-8% |
