Q:The PAR value of lamps and lanterns is what mean?
PAR photosynthetic active radiation abbreviations: photosynthetically active radiationPAR photosynthetic available radiation, green plants for photosynthesis process, absorption of solar radiation in the chlorophyll in excited state that part of the energy spectrum. About 400 ~ 700 nm wavelength, represented by symbols Qp, units of w/m 2. Photosynthetic active radiation is plant life activities, organic material synthesis and yield formation of energy sources.
Q:Led to shoot the light is broken how to change
Now turn off the lights switch (for safety) had better be to turn off the total power supply, and then into the drive power line (also can be directly cut short), then remove the bad driver And then put the new drive power input skin, two light thread dial the skin. Let one of the root drive power cord wrapped around the lamp power cord (chaozhou both positive and negative), on the one of tie up good, good electrical tape, another root connection same good tangle on electrical tape.
Q:Smallpox lamp is max25w LED power rating, is 25 watts
Max25w here is probably equivalent to a 25 w incandescent lamp brightness is 3-5 w power consumption
Q:On the ceiling lamp bulb is broken can change LED light bulb?
Can the LED to shoot the light, there are similar. If you compare the outlet is in line with the line.
Q:LED lamp burning halogen lamp cup of transformer
Is your estimate of transformer electronic transformer. High frequency and voltage instability. With a constant current source or inductance transformer next time. When I was home decorate is to ask the manufacturer. Did you change all buy it. Introduce you out of the blue lights. Is responsible for. Just tell me how to pack before I buy. There may be any problem. Do help to save money worry
Q:What are the kinds of led lamp holder?
LED lamps and lanterns of species LED lights, LED street lamp (Light Emitting Diode, Light Emitting Diode) the semiconductor lighting. It is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. It is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long service life, therefore, the LED street lamp will become the best choice of the road lighting energy saving reconstruction. LED project-light lamp, LED project-light lamp make specified by the intensity of illumination on the cliff above the lamps and lanterns of the surrounding environment. Say again the spotlight. Normally, it can aim at any direction, and has not affected by the climate conditions of structure. Mainly used for large-scale operations in mining, building outline, stadium, overpass, monuments, parks and flower beds, etc. Therefore, almost all the outdoor use of large area lighting lamps and lanterns can be seen as light. LED wash wall lamp, LED wash wall lamp, as the name implies, let the light like water washed metope, mainly is used for building decoration lighting, and used to draw the outline of the outline of a large building! Due to the LED energy saving, high photosynthetic efficiency, color is rich, long service life etc., so in 2013 other light source to wash the wall lamp is gradually replaced by LED wash wall light.
Q:The LED lamp heating temperature of 65 ° high
But if the light source on the heat doesn't pass all the shell, then 65 degrees it is hard to say, analyze the hot flow channel of light.
Q:Led to shoot the light, the 12 v transformer and transformer can general ordinary lamp?
Can't, because leds points of positive and negative polarity (dc), and ordinary lamp general both (ac). If money does not can be connected to use after rectifying, pay attention to the polarity.
Q:The led will shoot the lamp to warm the white heat?
All the leds will be fever, warm white and white or cold white calorific value is the same, different is only a person the sense of light, is not the same light warm white hot than cold white.
Q:Store decoration, good track shoot the lamp to LED lamp or metal halide lamp is good?
Each have each good, save electricity by leds. The light effect is good with metal halide lamp
