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: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:Courtyard lamp installation requirements are?

Solar garden lamps quoted manufacturers, Huangchuan Limin science and technology count. The individual packed many of the street lights.Speaking of the development of solar garden lights in recent years: we all know that because of the impact of energy and environmental pollution, people for energy-saving products have paid great attention to, hope that through this product to solve the current difficulties of social development, while the solar garden light is precisely with energy saving and environmental protection in this two kinds of advantages of the street, so the development of solar garden light is naturally supported.The advantage of energy saving solar garden light is reflected in its use of energy, solar energy resource is a product of nature, is a kind of renewable energy, has a very good advantage is "inexhaustible", so the courtyard lamp can use solar energy resources as its energy source, you can save it to an external power supply and the power to provide power, so that from the solar garden light is such a.

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

The system is composed of solar panel, bracket, lamp post, lamp holder, special bulb, accumulator, battery box and cage. The lamp cap is colorful, chic and elegant, and can be used for dressing and lighting in courtyards, parks, playgrounds and other places.

Q:What's a good place for solar garden lamps? Why should solar garden lamps be worth buying?

Individual orders solar garden lamps are generally in Huangchuan Limin technology, not only reasonable price, quality and after-sale very well.

Q:How much is the installation of the courtyard lamp?

Depends on whether you have to pull the wire, if only to dig the foundation installation, a light salary of about 150, but also depends on the number of installed.About courtyard lights, I hope I can help you, please adopt.

Q:How about the installation and subsequent maintenance of LED garden lamp?

After the test and operation of the lamp, after the installation of the lamp, after the insulation test has been checked, the test run is allowed. After power on, should be carefully checked and inspected, check whether the control of lamps and lanterns is flexible and accurate; whether the switch and the lamp control sequence correspond; if found problems should be immediately cut off the power, find out the cause and repair.

Q:How many meters is the courtyard light?

According to the width of the District Road, the illuminance of the road to choose different courtyard lamp holder (Lu Dengtou), each lamp design is not the same, the light distribution curve characteristics are not the same.District Road lights can choose 4 meters -5 meters. The distance between the street lights can be chosen 10-15 meters.Finally, there are cheaper, cheapest three hundred or four hundred to buy, but that quality is really not flattering. If you want to ask the quality is good, the price is relatively cheap manufacturers, you can see the Huangchuan Limin technology.

Q:Brand solar garden lamp which is good?

Compared with the conventional LED lens, this lens plays a polarizing enhancement effect, which is equivalent to the integration of two optical lenses and a primary lens. The main feature of LED garden lamps for lighting is the directional emission characteristics, because high-power LED are equipped with reflectors, and the efficiency of this reflector is significantly higher than the efficiency of the lamp reflector. In addition, the efficiency of the self reflector has been included in the light efficiency test of the LED. The road lamp LED should as far as possible the use of the characteristics of LED directional emission of light, so that all LED road lamps in the light illuminated areas directly at the road, and then use the auxiliary reflector lamps light distribution, to achieve reasonable integrated light distribution. It should be said that road lamps should be in line with the CJJ 45--2006 and CIE 31 and CIE 115 standards of illumination and illumination uniformity requirements, lamps should include 3 light distribution function. The LED with reflector and reasonable beam output angle has a good primary dimming function. In the light energy, according to the height of the street lamp and the width of the road, each I, the installation position of the ED and the direction of the transmitting light can be designed, and the good two time light distribution function can be realized.

Q:What is the distance between the garden lights and the courtyard?

According to the "garden" project, garden lights on the park and the main road green space, should use low power installed in the 3-5 meters 20-40 meters Zhuju lamppost.
