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: The cold white light LED lamp beads or warm white beads?: The light emitted by neutral white LED has more yellow and red wavelengths, and this spectral distribution helps to distinguish between different liquid surfaces on the tarmac.

Q: Features of LED street lamps: 2, LED street lamp has a unique two optical design, the LED street light exposure to the required lighting area, further improve the lighting efficiency, in order to achieve energy-saving purposes.3, LED has reached 110-130lm/W, and there is still great room for development, the theoretical value of 360lm/W. The luminous efficiency of high pressure sodium lamp is only increased with the increase of the power, therefore, the overall optical efficiency of LED lamp is better than high voltage sodium lamp; (the overall efficiency of light is theoretical, light effect actually more than 250W higher than that of LED high pressure sodium lamp).4, LED street light color is much higher than that of high pressure sodium lamp, high pressure sodium lamp color index is only about 23, while the LED lamp color index reached more than 75, from the point of view of visual psychology, achieve the same brightness, illumination LED lamp can average 20% lower than high pressure sodium lamp,.5, a small decline, a year decline of less than 3%, 10 years still reached the requirement of road, and high pressure sodium lamp failure, a year has decreased by more than 30%, therefore, LED lamps used in the design of power can be lower than high pressure sodium lamp.

Q: What are the components of a solar street lamp?: Solar panels used to transform solar energy into electrical energy; solar controller: used to charge and discharge the battery, also the battery charge, over discharge protection and timing switch for LED lamps; battery: electrical energy use for storing solar panels; LED lights: used for lighting in the night thank you!

Q: What is the design height and illuminance of LED street lamps?: 1, the first screenshot of table 5.1.3, Weff means: effective width of the road.2, the above lamps refer to conventional lighting, the so-called regular lighting is the lamp installation height of 15 meters below the lamppost.3, light cut type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-65 degrees.4, half light type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-75 degrees.

Q: What's the price of the LED road lamp holder?: Generally speaking, as the working environment of street lamps is the worst, it is normal to go to eight or nine dollars per watt.

Q: Why do street lights use bat wings to match the light curve?: Make full use of light. LED light is diffuse type, not only will be the problem of uneven illumination glare.

Q: Who knows the relationship between the number and weight of LED street lamp: The relationship between the number of LED light weight and beads, the strength of your life,Can not get a formula, a single lamp can be 1W, or 100WThe relation between street light weight and street lamp power can still be obtained, only at presentDie casting space aluminum cooling, about 100W, about 20 pounds

Q: How to distinguish whether the LED lamps glare seriously, whether there is a standard?: Glare can be divided into disabling glare and non glare. Any glare that reduces the vision of the human eye is called disabling glareReduces visibility of visual objects, but does not necessarily produce discomfort; the glare that makes people feel unhappy is called "no"Comfort glare.

Q: Is the power LED lamp constantly flashing? Is it a power supply problem?: If the driver has over temperature protection function, and material performance can not meet the requirements of heat lamps, driving over temperature protection work will have a flash out of the phenomenon, such as: 20W cast light lamp shell used to assemble the 30W, it will not do heat.

Q: How much is the rated voltage of the LED street lamp? Is it direct current?: It is worth noting that, if the solar LED street lights, then certainly the input DC, and as many volts, still depends on the situation.
