Q: How much is the LED to shoot the light, color rendering index in general: According to difference of each manufacturer to purchase the lamp bead and shoot the light color rendering index, general Ra between 50-90. LED white light than warm white color rendering index is relatively high, general manufacturer to produce LED lamp color rendering index in more than 70

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: LED lamp with a period of time why will flash?: Driven out of the column is the largest, the second is the lamp bead, driving power and light board and a matching problem will also have this kind of like now, that is to say driving power source or lamp plate lamp bead one appeared quality problem, does not match

Q: What the reason, is led guide to shoot the light flashing?: And it is flashing all the time, regular flash,.Suggest to merchants repair or replacement.This is not necessarily

Q: Aquatic plants cylinder light can use LED lamp?: Current leds are not suitable for plants, plants or a professional grass lamp is best, followed by the philips 865 color temperature (6500 k) and 6500 (color temperature 4000 k) series of tubes.

Q: What the difference between LED downlight and LED lamp?: LED tube light is a light shot inside the embedded in the ceiling lighting lamps and lanterns. Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighting or assist illume. With the continuous development of LED technology, the service life of the LED tube light now generally can reach more than 50000 small.

Q: The ceiling of a ceiling light is of general size: The first is the difference between the different wattage specifications: on the one hand the size of the lamp for 35 w generally has two kinds: The first is a opening, width is 205 * 90, the size of the high of 170; The second is opening, width is 243 * 106, the specifications of the high of 198. And 20 w lamp is generally only one, that is opening, width is 235 multiplied by 106, the specifications of the high of 198. A third type of even 50 w to shoot the light, the size of the gas is opening, width 235 * 106 plus 198.

Q: Why home outfit LED lamp has always been a bit weak after switch off the light: This phenomenon is a common problem, LED production called micro light disturbance stress, the reason may be: near ultraviolet (uv) light source excitation light glow fluorescent powder layer; Drive power supply design, no surge absorbing circuit of induction electric discharge, low light performance at the same time accompanied by flashing phenomenon; Drive power leakage quality problem, 220 v is shut off due to the exist lamp holder to switch is the power cord length, induced current LED light source series shimmer. Solution is the best in qualified driving power, the phenomenon of quality control means perfect manufacturer is not allowed to the factory, the product shape will test whether design light reaction, Induction light reaction has a passive remedy is to switch the fire try zero wire transfer. Special instructions as consumers accustomed to using fluorescent tube before, induction shimmer as normal, but the LED lamp product design can eliminate this problem, the quality management of serious manufacturer's product inspection is not allowed through, so do not assume responsibility should the user, can find manufacturers solve business

Q: Led to shoot the light is broken how to change: Nails dig is commonly used in the edge of the lamp tube (position) linking to the smallpox condole top, a little bit hard pull became one! Two used to locate the wire spring clip!

Q: What is the price of an led light?: The price of the LED lamp will not be too expensive. Such as watt led lamp 3 watt price 25 yuan. And some of the philips led to shoot the light 3 w is 65 yuan.
