FAQ
Q: Whether the LED lights really have 50,000 hours lifespan?
A: 50,000 or longer lifespan is only theory from lab test.But due to working environment are different from
in lab,actual lifespan is only <=30,000hours. Meanwhile it can also be 50,000 hours lifespan if it adopt very good material.
Q: For same power,why different suppliers with different brightness?
A: Different chips,or same chip but different brightness version.The brightness will be different.But for same chip
and same brightness version,the brightness will be slight difference.But please make clear the brightness difference
between LEDs and lamp fixture.
Q:What is colour temperature?A: Kelvin is a way to measure "temperature", the light from LED lights emit a certain color, which we have catagorized
in CTT(kelvin).For example, a warmer (lower color temperature) light is often used in public areas to promote relaxation,
while a cooler (higher color temperature) light is used to enhance concentration in offices.
Q: What is CRI?
A: CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.
Q: What is PF and efficiency?
A: PF and efficiency is to feedback the driver electrical performance.
- Q: LED street lamp burning black what reason?
- For example, when testing, due to the power supply instability caused by instantaneous high voltage, or misoperation caused by large current, static electricity will only occur somewhere above the chip black.
- Q: Why is the higher the current, the lower the light efficiency?
- Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power
- Q: How to judge the light type of LED street lamp?
- It will be tested by a large distributed photometric tester,
- Q: Why do street lights use bat wings to match the light curve?
- This is according to the common high-pressure sodium lamp street light distribution, and now the LED street lamp is just imitating him, oh, no one knows what to do later.
- Q: Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?
- Relatively large changes, small changes can lead to constant voltage power supply current so constant current drive is better, before use Fuhua electronic outdoor power personal feeling can still hope to adopt, oh, welcome to ask.
- Q: How to use ZigBee intelligent LED street lamp
- First, a ZigBee gateway, then use ZigBee lamp switch switch control, through the mobile phone, tablet and other remote control lights can be opened, you can also set the timer function in the software, the specified lamp open time and closed time, you can also add a light sensor, judging the cloudy lamp. Intelligent open or closed
- Q: What is the heat dissipation principle of a LED street lamp?
- Mainly include: natural convection heat dissipation, fan cooling, heat pipes and loop heat pipes, heat dissipation, etc.. The fan is forced to heat, the system is complex, the reliability is low, and the heat pipe and the loop heat pipe have a high cost of heat dissipation.
- Q: What's the reason that the LED street lights flash out?
- In addition, there may be LED damage. Among them, LED short-circuit, resulting in the number of LED series to reduce, LED voltage at both ends of low, low beyond the power output voltage range, at this time the power will protect, there will be flash phenomenon.
- Q: How to calculate the radiation area of solar LED street lamp
- According to the light distribution, the installation height and elevation of the lamp, it can be calculated by trigonometric function
- Q: High frequency jet lamp, LED lamp, xenon lamp, which is suitable for street lamps
- LED light color and soft, to capture and analyze details of road condition eye to night lighting, but due to the LED light emitting chip is heat sensitive, so the steady flow module and a heat dissipation module as big and complex, weight big, cost is very high, but from the actual situation, life did not claim so long. Even the shortest in several light sources. Many places use this as a source of care for the local light source industry.
