Q:How to distinguish LED lighting voltage?
Under normal circumstances, users do not pay too much attention to, with what kind of voltage level of LED lights, buy the corresponding level of voltage lights on the line.
Q: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.
The LED light source characteristic of solar street lamp has:1 、 high luminous efficiency, small power consumption, long service life and low working temperature.2 、 safe and reliable.3, the reaction speed is quick, the unit volume is small, green environmental protection.4, the same brightness, the power consumption is 1/10 of incandescent lamp, fluorescent lamp 1/3, and the service life is 50 times that of incandescent lamp, fluorescent lamp 20 times, is the fourth generation lighting products following the incandescent lamp, fluorescent lamp, gas discharge 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:Is there a difference between the landscape lamp and the courtyard lamp?
The layout of the courtyard lights should be avoided in the vicinity of the first floor residents, so as not to cause interference to the residents.
Q:Courtyard lamp installation requirements are?
The solar garden lights which use solar energy resources, we can learn that it's clean is very powerful, but there is a light source it is using low voltage LED light products, making itself have an advantage, because it does not contain mercury, light and not for glare problems. Therefore, the development of solar garden lamps in recent years is quite acceptable.
Q:LED how much is the courtyard lamp W?
Maybe 10w~15W. Listen to what a friend of the lighting department said. It's for your reference only
Q:Landscape garden courtyard lights, lawn lights, buried lights, plug lights, the general election of what light source?
Lawn lights, about 10 energy-saving lamps, play a decorative role, without too bright.Buried lights, now popular LED, 5-9W will do.Spot light, 3-5WLED.
Q:How much is the solar garden lamp?
Finally, some LED streetlights do not heat well:The 1.LED light source has great thermal resistance, and the heat of the light source can not be dispersed. The use of heat conductive paste will cause the cooling movement to fail.2. using aluminum substrate as the PCB connection light source, because the aluminum substrate has multiple thermal resistance, the light source heat transfer, the use of heat conductive paste will make the heat dissipation movement failed.3. no room for the light emitting surface of the thermal buffer, LED light source will cause heat failure, failure in advance.
Q:Which brand is good for the patio lamp?
Check the lights solar controller and battery is lit, if not bright, then look at the connecting line controller and battery is not off, if the connection line is normal, the voltage with a multimeter to check the battery, if the battery voltage is normal, the controller, the replacement of a controller see is not normal use.
