Q:What should I pay attention to when buying street lamps?

Pay attention to the LED chips used in LED street lights. LED chip is the core part of LED street lamp, and the quality of LED chip affects the service life, brightness, light color of LED street lamp, etc.. In the purchase of LED street lamps, it is necessary to make sure that the LED lamps provided by the manufacturer are where the LED chips are used. Generally imported LED chip quality is slightly better, but the use of imported LED chip LED street lamp prices are quite expensive.

Q:The width of the road is 20 meters, the distance of the street lamp is 25 meters, and the number of tiles is led. How much is the pole?. How to calculate?

General road light source is about 250W,If you use LED, there are enough 72---108W, but the earlier to buy more expensive lights, in terms of long-term interests, LED to energy-saving much more cost-effective.The lamp pole is 7----12 meters high and the distance is 30----45 meters.Zhejiang Yao Liang lighting specializing in the production of various types of outdoor lights.

Q:How high should the installation height of the LED street lamp be?

In order to avoid glare, you can choose the f (d) (E), the installation height of street lights should not be less than 4.5m. The distance between the poles of the street lamp can be 25 to 30m, and the distance between the lamp posts entering the curve should be reduced appropriately.

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:How much is the price of the LED street lamp?

Tens to hundreds of dollars range, this depends on what you focus on the LED street lights? Guoqiang photoelectric cost-effective lamps

Q:What is the active power of LED street lamp? What is the relationship between input voltage and current and power?

When the AC current is over load, the AC voltage added to the load generates a phase difference with the AC current through the load, and the concept of power factor is derived from it. People produce and live electricity from the grid, which provides alternating current of 50Hz or 60Hz. As AC load, there are three types of resistance, inductance and capacitance.

Q:Why do street lights use bat wings to match the light curve?

The bat light curve of the street lamp is based on the light distribution of the common high-pressure sodium lamp. Now the LED street lamp is just imitating. The bat wing curve gives full use of light. LED light is straight scattered, not light, glare, uneven radiation and other issues.

Q:How to choose the power of solar street lamp?

Disadvantages: the distance of energy saving lamp is short and the illumination can not be satisfied. Energy-saving lamp light generally 10-20%, energy-saving lamp life in about 8000 hours, the maintenance cost is high; the main comments: energy-saving lamp suitable for commercial lighting, Home Furnishing lighting and plant lighting, not suitable for road lighting. 2, street lamp energy-saving cabinet, the energy-saving equipment mainly through the reduction of the overall voltage of the line, to achieve the purpose of energy saving.

Q:How to connect the lightning arrester of LED street lamp?

Protection end is divided into two, power supply side, if it is PVC line pipe, then in the bottom of the metal rod configuration protection rectifier power supply, constant current regulator source. Protection level is level 3-4.The fifth stage of LED is the lightning protection parts of lamps and lanterns, and the low-voltage potential precise clamping protection. Ensure 24V or 36V DC voltage safety. The tip here is an exact clamp.

Q:Features of LED street lamps

LED street lamp has automatic control energy saving device, which can realize the maximum possible reduction of power and save energy in meeting different lighting requirements. Can realize the computer dimming, time control, light control, temperature control, automatic inspection and other user-friendly features.
