Q:What is the meaning of the "LED 3.5M 50W" street lamp?

The lamp pole height is 3.5 meters, 50W power, LED street lamp. Zhongshan open and close electrical appliances produce intelligent LED street lamp, the quality is good, the price is substantial.

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:Will the wisdom of street lamps be the future of development? At present, which is more reliable?

At present, China vigorously promote the construction of smart city, so the wisdom of street lighting is also the future trend of development, will replace the traditional street lamps. At present, the wisdom of street lighting manufacturers are many, a representative can Baidu, "Shanghai as if through" the company's wisdom, streetlights have been successfully piloted.

Q:LED street lights installed on both sides of the road, horizontal installation and angle installation (0~30 degrees), natural convection heat dissipation, that good heat dissipation.

The angle of heat dissipation is good, because the general hot air will spread upward, and the slope is more convenient for the diffusion of hot gas.

Q:Who knows the relationship between the number and weight of LED street lamp

However, depend on the number of street lamp beads on LED lights for the light source that is. For example, some integrated chip LED can achieve 180W or higher power with just one LED. The use of high-power LED light source will require dozens of.

Q:What are the prospects for the development of intelligent LED street lamps?

Before 2015, LED Street will remain around 50% compound annual growth rate, by 2015, LED road lighting lamps in the field (mainly for street lights and tunnel lamp) the overall penetration rate reached 46%, the next two years will add more than 30 million LED street lights and tunnel lamp. These favorable expectations have brought greater potential for development of LED street lamps.

Q:Is it suitable to install toughened glass cover on the luminous cavity of high power LED street lamp?

This is expected to affect the heat dissipation of high-power LED, heat dissipation is the most important issue, 100% lighting

Q:What is the distance between the usual street lights?

There is no standard, and some are required to achieve the value of illumination, there is no hard and fast requirements, generally speaking, the distance between the street lamp and the lamp height and the number of watts.

Q:LED street lamps must be constant flow source? No constant current source, can I?

Sure, but you have to pay a higher price! Not constant flow is generally constant pressure, you give each LED are constant pressure, then the price will be very high, and the current is not good control, easy to burn LED.

Q:30W LED solar street lamp 6 meters high, about how much?

30W solar street six meters with 6 m pole appropriate light source lamp Taiwan Jingyuan, intelligent controller with constant current controller, battery 90AH, Q235 hot dip galvanized steel pole adopts whole, including arm, cage.
