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

Power supply efficiency of LED street lampThe input power minus the output power value of this parameter is particularly important, the greater the value of efficiency is low, it means that there is a large part of the input power is converted into heat emitted; if it is installed in the lamp will produce a very high temperature, a light effect of our LED plus than the heat that will produce higher temperature superposition.And all of our internal power electronic component life will decrease with the increase in temperature. So the efficiency is the most fundamental factor power life, efficiency is too low, otherwise the heat consumption in the power supply is too large. Non isolation efficiency is higher than the isolation type, generally more than 80% on it, but the efficiency and the light plate matching method related

Q:3 meter tall courtyard lamp foundation specifications?

Conventional garden lamp foundation is generally 1/10 of the lamppost height, that is, 3 meters courtyard lamp, conventional foundation 30CM, but if you need to install in wetlands and water, you need to increase the height of the foundation.

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:Why lawn lamps are gradually replacing traditional courtyard lights?

Although lawn lamps and garden lamps are garden decoration lamps and lanterns, but no one can replace who, the effect is different, can only say from the material, light source, innovation.

Q:Landscape garden courtyard lights, lawn lights, buried lights, plug lights, the general election of what light source?

Golden halogen lamp or LED lamp, cold light source is best, warm light source is still used in landscape

Q:Disadvantages of solar garden lamps

Secondly, solar garden lights shortcomings many people say is the investment cost and the maintenance cost is high; in fact, compared with the use of electricity, energy saving and environmental protection, solar garden lights and wireless connection, the installation and maintenance costs is not needed.

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

It is difficult to determine the power of the LED street lights used on a particular section of the road, but it can be estimated from the street lights seenThere are a lot of a lamp of general LED lamp, according to a count of each tile

Q:Garden lamp installation project quotation template

The advent of single high-power ultra brightness LED is the LED application field, it is possible to cross the high efficiency lighting market, and will be one of the greatest inventions after Edison invented the incandescent lamp.

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: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.
