Basic specification:

Q:What are the standards for LED street lights?: Generally not too high standards, the whole system is a combination, but the material is different

Q:How can the LED outdoor lamp be grounded?: When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q:Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?: General is constant current power, street light is not clear, but 90% are constant current power.

Q:What's in the lamppost of the LED street light? What is the function?: LED street lamp has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for energy saving reconstruction.

Q:Does the LED explosion-proof floodlight work well? Can I use it in a chemical factory?: No matter how with LED lamp will not explode, our industry has not LED explosion-proof lamp that is a lie, just like someone took a stone to sell to you to tell you that the three stone is not the same as with the other will not explode, this is deceptive argument. It can be used entirely in a chemical factory. No matter what the lights are, they produce tiny arcs at the moment they are energized. As long as the use of environmental ventilation, flammable explosive flammable air in the environment to achieve the standard, there will be no accident

Q:Who knows LED street lamp warm white light and positive white light have what difference, how should choose?: If the power is the same, the brightness of the white and warm white light should be the same.

Q:What's the difference between a spotlight LED and an astigmatic LED?: The spotlight is high in some point or direction, low in other directions, similar to searchlights.

Q:How to install the garden lamp?: You should probably pay attention to the following when installing the garden lights:First, open the package and check the integrity of the garden lamp;Then, the wiring should be assembled with reference to the instructions:A, open the lamp, light source and electrical equipment installation.B the leads are drawn from the through hole to the bottom of the lamp post.C then connect the lamp holder to the lamp post, and tighten the fastening screws.D, the courtyard lamp flange and foundation embedded screw alignment, vertical stand.E, the use of a nut or pad after leveling tighten the mounting nut.F, done!

Q:How to lay the courtyard lamp in the district?: 1. AC power supply is 15% less efficient than solar energy, that is to say, to obtain the same output power, the AC power will be more than 15% of the input power. And the power factor, if not compensated, will lead to reactive power increase of the grid.2., the biggest advantage of solar LED street lights is that they don't have to pay the electricity bill at all. A 250 Watt High pressure sodium lamp costs about 766 yuan per year. 20 million street lamps, electricity, an expenditure is 15 billion 330 million yuan.3. ordinary high-pressure sodium lamp life is only 3000-5000 hours, and LED life of up to 30000-50000 hours, and with the progress of technology, LED life is likely to be as high as 100 thousand hours.

Q:What are the parts of a LED street lamp?: System design ideas, solar street lighting design and general solar lighting compared to the basic principle of the same, but need to consider more links. The following will be the solar LED high-power street Hongkong Industrial Group Co., Ltd. as an example, several aspects of analysis.
