FAQ

How can you tell the quality of a solar garden lamp?

Must first understand the lamp solar street lamp is LED lamp, it's thin and thick shell is a factor, the structure inside the aluminum substrate, the aluminum structure, than the size and thickness of these things can determine the basic quality of the lamp.

LED how much is the color temperature of the courtyard lamp?

If there is a moonlight at night, then warm and white, with the moonlight around you, will enhance the overall color hierarchy of the courtyard.If the garden is unique to you, warm white is a good choice.

What's the quality of the solar garden lamp?

LED street lamp, power supply, heat dissipationThe main factor of the heat dissipation scheme is that the power supply beads of LED street lamp can be greatly extended under the condition of no overheating. Generally, aluminum alloy is easier to be cooled by heat dissipation. That is, LED street light, power beads attached to the aluminum substrate, as far as possible to expand the external heat dissipation area.The face of such a broad LED market is full of vitality, the main scientific development, in a number of technical areas to achieve a leading position, I believe that China's LED enterprises will become more powerful.

How to configure solar garden lamps?

Following solar LED lighting market trends analysis: 1. solar LED lighting presents the following three characteristics: the rapid decline in prices, domestic installation growth slowed down significantly, and the rapid growth of the export market. Of course, there must be a cause, and the emergence of this phenomenon has a certain relationship with all aspects. First, to further enhance the LED technology, LED outdoor lighting problems of functional heat dissipation, attenuation, power and other problems being solved. At the same time, the rapid decline in upstream chip prices, LED outdoor functional lighting products to enhance the performance price ratio. Secondly, the government promotes LED outdoor functional lighting products to speed up the promotion. Governments all hope to realize energy conservation and emission reduction by installing LED street lamps and LED courtyard lights, while achieving good social benefits.

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.
