Q:Led streetlights power down half, through what?

In order to save the power consumption, LED street lamps design the power of the first half of the night and the latter half of the night power, and the power drop of the LED street lamp is realized by the controller,

Q:What is the difference between solar LED street lamp and ordinary energy-saving street lamp?

1. from the purchase and installation cost, LED solar street as general lights are more expensive, but without the solar street lamp cable as set up, just dig a hole and the embedded parts, battery, lamp base buried secure can, so many cable and labor costs, in fact, the price difference between divergent and general lighting.2., from the use of the role of view, LED solar street lamps using the latest LED light plate, lighting effect is generally more than 2 times the energy-saving lamps, and more energy saving role, self-sufficiency in the form of power supply is also unmatched by general street lamps.3., from the quality and after-sales point of view, LED solar street lamps choose hot galvanizing and other high-tech skills, the use of data is much higher than the general quality of street lamp poles. Today, the LED solar street lighting industry is in high-speed development period, many solar street lighting manufacturers after-sales service is also close to, as if the perfect situation.

Q:How many LED lights are there in the downtown area, W?

200W, 12 meters high, 4 lanes160W, 10-12 meters high, 3 lanes, 4 lanes120W, 8-10 meters, 3 lanes80W, 6-8 meters, 2 lanes, 3 lanes

Q:Installation method of high-power LED street lamp

Pay attention to the arrangement of exterior lines of all kinds of devices in case of polarity error. The device should not be too close to the heating element, and the operating conditions should not exceed its specified limit.

Q:How to use ZigBee intelligent LED street lamp

Because every time there is a street lamp, through the method of adding repeaters, ZigBee can now add more than 60 thousand devices for a city should not be a problem, if more street number more than 60 thousand, can be divided into several pieces respectively. In general, the distance from each repeater is about 70 meters, and it will be better if there is no blocking outside, and hundreds of meters are no problem at all. If the effect is not good, you can add a repeater in the middle to resolve it.

Q:Who knows LED street lamp warm white light and positive white light have what difference, how should choose?

Because the light intensity of the human eye light is higher than that of the warm white light, the naked eye will feel that the white light is brighter than the warm white one.

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: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.

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:Why is the higher the current, the lower the light efficiency?

What I know is: junction thermal resistance, spectral distribution drift
