Q:How much ballast does the LED 15W lamp belt need?
The key is the light effect of LED. Light effect LED beads are currently available from 40LM/W~100LM/W, see what you buy. Incandescent light effect is about 10LM/W, LED whole lamp, if it is cheap Zhongshan goods, it is estimated that 30-40LM/W, okay, you can go to the 60-70LM/W, PHILPS light Expo in the sample displayed, you can go to 90LM...The LED lamp uses a constant current source, not a ballast, and the output power of the constant current source should be greater than 100W, and the specific value depends on the setting
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:Courtyard lamp installation requirements are?
Yard lamp installation requirements are not fixed, depending on the user's requirements and configuration design, and specific manufacturers to communicate on it.
Q:How to install the garden lamp?
Affordable solar garden lamp factory, it is suggested that you can go to Huangchuan Limin technology solar street lamp factory, you can customize the production of a number of solar garden lights.
Q:LED how much is the color temperature of the courtyard lamp?
Generally choose warm white, 4500K or so.If the color temperature is too low, it will appear dim. Too high, winter will be too cold, summer will attract more insects.
Q:Consult the advantages and disadvantages of the metal halide lamp and the LED miner's lamp
Application and energy saving comparison between high power LED lamp and high pressure sodium lamp, metal halide lamp and energy saving lampHigh pressure sodium lamp is widely used in roads, tunnels and factories lighting, and high pressure sodium lamp has the disadvantages of slow start, high strobe, large power consumption, Wen Shenggao and noise headlamps. Metal halide lamp with luminous efficiency good, is widely used in factories, shopping malls, city lighting, road lighting, stadium and other metal halide lamp; but generally has short service life and large power consumption, light flicker and glare, power with large voltage fluctuations and slow start, bring a lot of trouble. High power LED lamp R & D and production of our company, with 50 thousand hours of life, energy saving, high high luminous efficiency, high color, no flicker, instant start restart, free maintenance and many other advantages. LED lamp will completely replace high-pressure sodium lamp, metal halide lamp site applications.
Q:3 meter tall courtyard lamp foundation specifications?
300MM yes, you can make it round, too. I bought a flower pot and made a hole at the bottom. It was good and easy to use as a base.
Q:What wire is used for the garden lamp?
According to the provisions of the "city road lighting design standards": the average illuminance uniformity of 20lx expressway, trunk road 0.4, the average illuminance uniformity of 15lx, 0.35, secondary roads average illuminance uniformity of 0.35 8lx, the average illuminance uniformity of 5lx branch, 0.3.
Q:How can the LED outdoor lamp be grounded?
One end of the wire is connected to the LED shell, and the other end is buried close to the ground.
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.
