Q:What's the quality of the solar garden lamp?

LED series parallel connection and PFC power factorElectronic components work within the rated voltage range, the smaller the current, the longer the heating life, and the shorter the life expectancy. LED street light power beads are sensitive to AC volume, and the higher the AC volume, the worse the light comfort.Generally use electrolytic capacitor to maintain the voltage, as much as possible to reduce the output voltage, AC volume, the bottom pressure, electrolytic capacitor capacity can not be too small, capacity and output current ratio of 1UF<1.5MA, otherwise LED will appear flashing. Non isolated input terminal, high voltage electrolytic capacitor, the choice is the same as isolated, and the output capacitor is 1UF<6MA. Dimmable LED power supply at the output terminal electrolytic capacitor to meet 1UF<0.5MA.

Q:How many watts of energy saving lamps are suitable for the three meter courtyard lamp? How many watts of LED?

The same brightness, if LED to 10W, energy-saving lamps about 30-40W, incandescent lamp to 100W, three meters height 10W enough, solar street lights 5 meters high, only to use 12W, it is very bright

Q:The advantages and disadvantages of LED and solar garden lamps

Solar garden lamp, the shortest life is the battery, about 4-6 years to change the battery (the current battery technology can only achieve this life), solar energy have a great advantage is more environmentally friendly, solar systems are now relatively mature, can choose natural products beneficial to some is responsible for yourself.

Q:Consult the advantages and disadvantages of the metal halide lamp and the LED miner's lamp

Main production: landscape lamp, lamp, road lights, garden lights, LED lights, solar lights, LED lights, lawn lamp, underground lamp, electrodeless lamp, lifting lamp, lighting engineering, and related accessories business.

Q:Which brand is good for the patio lamp?

Then check that the controller load indicator is lit, you can check with the meter, detect whether there is an output voltage, and if there is no voltage output, replace the controller.

Q:What are the types of LED garden light sources?

The common corn corn straw hat light lamp and LED lamp LED surface light source lamp and the LED light source of the maize patch do, LED light source and surface light source patch is the source of good quality, large quantity of long life light decline is small, the corn straw hat light lamp quality, is already a few years ago the obsolete products, but some manufacturers in order to lower prices in the.

Q:How to determine the power of LED street light?

LED street lamp power LED street lamp power and rural branch city road has no clear standard, but in general: LED lamp power city road about 80W-250W LED Street Village Branch power about 30W120W.

Q: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.

Q:Introduction to garden lamp components

A courtyard lamp is mainly composed of 5 components are: light source is an important part of all lighting products, according to different illumination requirements, can choose different brands, different types of light source, light source commonly used are: incandescent lamp, energy saving lamp, fluorescent lamp, lamp, lamp, Jin Lu ceramic metal halide lamp, as well as new LED light source.

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.
