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: What is the grade of protection for Mega LED road lamp holder?
- Street lights, then the higher the level of protection must be good, the market that can reach IP65, it depends on how the quality of the product, the better the quality, protection level more reliable.
- Q: What do you pay attention to when choosing LED street lamps?
- First, we should pay attention to the relevant photoelectric properties (such as light type, luminous flux, luminous efficiency, color temperature, power, rated voltage and current parameters);
- Q: Is the street lamp good with LED or solar energy?
- Hello The two concepts, the LED street lamp and the solar street light, are in themselves no conflict, just as you think, are you wearing a black coat or black shoes today? The actual two do not conflict.
- Q: Technical requirements for LED street lamps
- The technology is mature day by day, and the efficiency of light source has reached over 100lm/W, which makes it possible to save energy in urban street lighting. LED street lamps, especially large power LED street lamps, are attacking the traditional street lamp market at a tremendous speed.High power LED street lamp, as its name suggests, is power greater than 30 watts, using a new type of LED semiconductor light street lamps. The standard is generally the illuminance uniformity of the road surface, which conforms to the illumination of the road. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX. Refers to the use of solar panels for the supply of power LED street lamps. The conversion rate of 1. light is 17%, the solar energy per square meter is 1000W, and the actual utilization efficiency is 170W
- Q: For the LED street light distribution, is it better to use a lens or a reflector?
- According to personal needs, the last time I went to a lighting shop called Zhongshan Ming lighting shop to buy lights, but also asked the question, but do not remember what the salesman said
- Q: What is the reason for the low power factor of LED street lamp?
- The LED street light power is generally more than 100W, if the power factor is low, it can only show that its driving power supply, there is no power factor correction, or is not done well.Well done, it should be more than 0.95.
- Q: What heat sink is best for LED street lamp radiator?
- What is the external force of heat, force, that is to say, with the use of external heat, fan in the lamps or using superconducting tube, water-cooled, and so on, the advantage of active heat dissipation, efficiency has been improved, but the structure is complicated, the cost is increased, and the service life of the cooling equipment is generally not too long, less than 2 years is basically finished.
- Q: How is the minimum illuminance of LED street lights Emin obtained? How to calculate?
- Import the IES file of lamp into DIALux software, and then set up the height, elevation angle, installation interval and so on
- Q: LED street lamps must be constant flow source? No constant current source, can I?
- Now generally constant current power supply, if not the constant current power supply has a great damage to the lamp
- Q: What are the advantages of LED road lights?
- High luminous efficiency. Incandescent lamp, halogen tungsten lamp, light efficiency of 12-24 lumens / watt, fluorescent lamp 50-70 lumens / watt, sodium lamp 90-140 lumens / watt, most of the power consumption into heat loss. LED light efficiency will reach 100-200 lumens / watt after improvement.
