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 light dedicated drive power 98W14 string 7, and ask 14 string 7, and what does that mean?
The 14 LED are connected in series to calculate a set, and then there are seven groups, which connect the seven sets of positive and negative electrodes to the negative pole, i.e., the seven groups are connected in parallel, and this is the meaning of "14 strings of 7".
Q:LED street lights around 2800K, the highest color temperature, how many lumens per watt?
Now LED 2800K color temperature, the maximum light effect is about 130LM/W
Q:What is the reason that the range of the LED100W street lamp is not enough or the brightness is not enough?
LED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting.
Q:Which is better, the LED street lamp and the traditional street lamp?
LED well, because it's energy efficient and bad, it doesn't affect anything else
Q:Why is the higher the current, the lower the light efficiency?
What I know is: junction thermal resistance, spectral distribution drift
Q:How many LED lights are there in the downtown area, W?
Depends on the width of the road, the normal is 250W metal halide lamp, there are 400W.. Used at intersections,
Q:Energy saving control of street lamps can save energy?
Street lamp wireless monitoring system: the "three remote" monitoring system is adopted, and the lighting monitoring system is composed of a microcomputer network system of the central dispatch room, a wireless communication system and a street lamp switch box and an intelligent terminal. According to the local time of sunrise and sunset and light value, a control method with time control and light control combination, automatic remote control on / off through the wireless channel, and can intelligently adjust the voltage, voltage, current, power and other field telemetry data, but the data was collected and analyzed, so as to judge the lamp operation.
Q:Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?
General is constant current power, street light is not clear, but 90% are constant current power.
Q:How many watts does the LED street light have?
The technology is mature day by day, and the high-power LED light source can meet the needs of general street lamps. The general optical efficiency of high pressure sodium lamp is 100LM/W, high power LED is commonly used by foreign 50-60LM/W, the best LED chip can reach 80LM/W, the luminous efficiency is high, means that the energy saving effect is better, which is the choice of one of the most important indicators of LED street lamp. However, the LED standard does not specify this, so the purchase of LED street lamps must be carefully confirmed.
Q:How much is the price of a LED street lamp?
The price involves many aspects, generally, for main roads around 120W 1100~1300 are normal; for the auxiliary road around 60~80w 500~800 prices are.
