High Refresh Radiator Fan Outdoor LED Advertising Screen For Large Squares
P8 radiator fan Outdoor Led Screen for shopping center for large squares
1. Using high-grade chip packaged LED lights, low gray and high brightness, fully guarantees the service life and display quality of the display screen.
2. The advantage of this driver chip is that it can reduce the voltage falling on the output terminals of the IC. Reduce the power consumption, improve the power loss of the IC, and then achieve the effect of energy saving.
3. a variety of module sizes , flexible collocation, more considerate upgrades , strict material selection

FAQ
Q1. Can I have a sample order for led light?
A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
A: Sample needs 3-5 days, mass production time needs 1-2 weeks for order quantity more than
A: Low MOQ, 1pc for sample checking is available
A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 3-5 days to arrive. Airline and sea shipping also optional.
A: Firstly, let us know your requirements or application.
Secondly, we quote according to your requirements or our suggestions.
Thirdly customer confirms the samples and places deposit for formal order.
Fourthly We arrange the production.
A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.
A: Yes, we offer 2-5 years warranty to our products.
A: Firstly, our products are produced in strict quality control system and the defective rate will be less
than 0.2%.
Secondly, during the guarantee period, we will send new lights with new order for small quantity. For
defective batch products, we will repair them and resend them to you or we can discuss the solution
including re-call according to real situation.
| 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% |
