- 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: Friends have told me that the Hong Kong star can lighting production of LED lamp, LED bulb light. LED daylight tube is very save electricity, I find for a long time to find, now share with you what? Who can tell me what is he power-saving principle?
- The lamp is incandescent lamp, principle of the first generation is heating filament under inert gas protection. Filament to a certain temperature when the potential energy of the electrons of the atoms of the outer is elevated to the unstable state, outer electrons when atoms never returned to steady state stability of high energy status will emit light. The working principle of this makes the most of the electrical energy into heat energy, can light energy is less than a few percent, efficiency is very low. The second generation of the electric light is a gas discharge lamp, including fluorescent lamp, fluorescent tubes, energy-saving lamps. Most of these lamps using high voltage ion release ultraviolet phosphors into visible light. So you need not too much heat loss, greatly increase the use of electric power, its luminous efficiency can reach twenty percent. The third generation of the light is LED (light emitting diode) lights, main points, high power and small power and different colors. The LED is the only principle of solid state light emitting light. Using cavity semiconductor PN junction and electronic to move atoms bond change rates can be released in the form of light. Because of the different semiconductor materials can be directly send red, yellow, green, blue and ultraviolet light. Blue light and ultraviolet light and fluorescent powder into white light. Do not need temperature and high pressure due to the working principle of the LED, so in theory to waste the least amount of electricity. Practice on the white LED is also continuing to improve photosynthetic efficiency. At present the highest photosynthetic efficiency can reach above thirty percent.
- Q: 18 w changed other power drive not bright LED lamp, what reason be?
- 42 v only do as much as 14 w, this is the most basic request, if I see this kind of drive is absolutely can't use, because the basic common sense all wrong, quality), the voltage is not enough, so is certainly not the light, do you want to buy a maximum output voltage at least 54 v drive
- Q: What is the difference between LED ceiling lamp and LED downlight
- Tube light is owed to the dark mounted, diffuse light, mainly to adjust indoor light color effect,, shoot the light is mounted, direct light, is mainly used to highlight the background picture or object, two kinds of lamp is installed at the top. LED tube light is a kind of relative to the ordinary lamps and lanterns has concentrated sex of lamps and lanterns, is generally used for general lighting or assist illume. The lamps and lanterns of LED lamp is a highly concentrated, its light is a specific goal. Mainly used for special lighting, for example to emphasize a very tasty or is a very interesting place.
- Q: With current meter how to detect the led lamp lights, bad
- Can find a lithium battery (or 3 section dry cell in series), series a hundreds of the resistance, to the led lamp bead, try on the reverse, if the light is good, light is not bad
- Q: What's the reason why LED lamp explosion?
- I come to the conclusion: your power supply voltage abnormal! Possible reasons: with your power supply system of a steal, (often at night, more time is that a) steal operation make the zero line suddenly dangling leads to voltage surge, relatively high voltage regular bulbs, not necessarily immediately, overflowing LED lamps and lanterns is very sensitive to voltage, slightly on the high side is easy to burn off one of the components (often capacitor). search Suggestion: immediately report power supply company, one night about the same time to check the meter box line condition!
- Q: How much led to shoot the light tile in the living room
- LED lamp is to use leds as a light source to shoot the light. Traditional lamp used more halogen lamp, luminous efficiency is lower, more power consumption and environment temperature rise by illuminate, service life is short. LED light source on the luminous principle, energy-saving, environmental protection level are much better than traditional lighting lamps and lanterns. And LED the unidirectional formed to shoot the light distribution of the perfect support.
- Q: Excuse me how many W LED lamp appropriate gallery
- Color rendering index suggested that more than 80 Ribbon star lighting technology
- Q: Why home outfit LED lamp has always been a bit weak after switch off the light
- You switch the thread is not the line of fireAs long as you do wire switch, to ensure that there would be no light.
- Q: Led to shoot the light, how much is seven bubble of v
- Due to the led constant current drive better. If direct use direct current (dc) according to the lamp bead by up to 85% of current TV university. Current or high voltage droop dawn soon.
