Q: The power consumption of a street lamp?
Also consider ballast power dissipation
Q: How to identify LED street lamps do well or not?
Overall, 1 lumens per watt lamp (what is the value of the lamp lumens not) are now generally more than 85LM.2, the light distribution curve of the lamp is how, now popular is bat wing light effect.
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: How many volts is the wind power streetlight led?
The difference between LED street lamp and conventional high-pressure sodium lamp street lamp is that the light source of high-power LED street lamp adopts low voltage direct current power supply and high efficiency white light diode synthesized by GaN based power blue LED and yellow phosphor
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: What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?
There are differences, LED lights brightness and illumination will be greater, Zhongshan Ming inter lighting is specializing in the production of lightsAnd other outdoor lamps.
Q: Energy saving control of street lamps can save energy?
Midnight lights: as the name suggests, in the evening when the amount of half the amount of light, only half of lighting to meet the requirements. As the voltage is proportional to the change with the load, after entering the middle of the night when the load is reduced, the voltage higher than when lights before midnight light, and at this time on the road, pedestrians and vehicles to reduce, put half the street lamp can meet the lighting requirements. The night lights have a variety of luminaire-distribution-style, many of the commonly used vibration rod.
Q: Is it suitable to install toughened glass cover on the luminous cavity of high power LED street lamp?
Can install the toughened glass, tempered glass resistance explosion-proof Guangyu lighting
Q: Location of constant current source for LED street lamp
Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.
Q: How is the minimum illuminance of LED street lights Emin obtained? How to calculate?
If you want to measure the value, I can only say that the approximate, because the illuminance value on a point value, the actual measurement is the target area is divided into small areas of uniform, center to measure each region with the value of the measured value, there is a minimum value.
