Q:Excuse me how many W LED lamp appropriate gallery

Color rendering index suggested that more than 80 Ribbon star lighting technology

Q:Aquatic plants cylinder light can use LED lamp?

Can carry out photosynthesis, aquatic plants,

Q:The same power of cob and led lamp which is brighter

LED lamp now single lamp and COB of useful products, according to the principle of the photosynthetic efficiency can distinguish under the same power that or bright.

Q:Led to shoot the light is broken how to change

Light bulb and the reflector lamp cup is an organic whole, first pull the lamp cup on the back of the power supply (ceramic system, circular!) To remove the O type spring clamp, pour lamp cup!!!!!! Check mark on the lamp cup, the wattage and voltage requirements, shoot the light points, high voltage (220 v) and low pressure (below 36 v) two! Don't mistake!!!!! Not sure if he took the old lamp cup reference to purchase! A few bucks!

Q:Shoot the light is led lights

Lamp are ordinary lamp and LED lamp, but with the development of science and technology, the ordinary lamp has been basically eliminated, so now on the market said to shoot the light is narrow sense points to the LED lamp

Q:18 w changed other power drive not bright LED lamp, what reason be?

VF values of each lamp bead is about 3-3.4 V, so a series of at least 18 to 54 V, general situation, the output voltage won't do more than 50 V, because it is not safe (of course, the use of isolation was not drive), so will make it 2 and 9 series way for more than 27 V (voltage), but not see your driver clear this After a few short also cannot do 3 * 18 w, because your lights must be 1 w (300 ma), rather than a 3 w (600 ma), current headlight bead hold, within a few hours it broke

Q:Is the radio light charged?

Relatively to shoot the light is very inefficient, but shoot the lamp to come out the effect of other lights can meet again, general design of the lamp decorate in the family, it is an ornament! Glass small shoot the light (quartz lamp) is often used in family support lighting, concentrated sex is strong, more used in corridor, adornment, wine and other lighting, and the use of a large group. Because the lamp filament light and has a high temperature, the shortcomings of short lifetime and great power consumption, quartz glass lamp temperature can reach 150 degrees above, there will be light roast color, or the hidden trouble of the fire caused by the temperature too high. Used in every 15 to 35 w quartz lamp, 5 hours a day, to electricity, 450 yuan a year. Reference electricity contrast: family 5 hours/day (0.48 yuan/degree) business 12 hours/day (1.00 yuan/degree) Quartz lamp 20 w... 17.5 yuan/year... ...... 88 yuan/year Quartz lamp 35 w... 30.66 yuan/year... ...... 153 yuan/year 50 w quartz lamp... 43.75 yuan/year... ...... 219 yuan/year 1 w LED lamp... 0.875 yuan/year... ...... 4.38 yuan/year 1 w LED lamp a year 24 hours a day using electricity: 24 x365x1x0. 48/1000 = 4.2 yuan Suggest using high-tech products LED lamp to replace, LED to shoot the light, long life (in theory is more than 50000 hours), is more than 10 times of quartz lamp, an LED lamp life, quartz lamp need to replace more than 10-20, although China imported the unit price of LED lamp is approximately equal to the traditional lamp (osram), but the LED lamp

Q:Led to shoot the light, how much is seven bubble of v

Search you said 7 outside lights, you can use the 24 v measure. In short don't exceed the limit of the current largest, there is no problem. Just a little bit small current is not bright or not bright. There will be no other problems.

Q:Reinstall the 2 LED lamp are in parallel, one open and how a first shines a stare blankly only 1 SEC,

Now is not to say that on the driving power supply technology is very poor, so belong to normal phenomenon. You can use it

Q:How can you make the led lamp not dazzling

Into visible light solid state of semiconductor devices, it can be directly put DianZhuan into light. The heart of the LED is a semiconductor chip, chip attached on a bracket, at the end of the end is negative, the other end connected to the power of the anode, the whole chip is encapsulated by epoxy resin. Semiconductor chip consists of two parts, one part is a p-type semiconductor, dominated by holes in it, the other end is n-type semiconductor, here is mainly electronic. But this two kinds of semiconductor connected, forming a p-n junction between them. When a current flows through a wire to the chip, the electron will be pushed P area, electron and holes in the P zone compound, then will be issued in the form of photon energy, this is the principle of LED light. And the wavelength of light was the color of the light, is determined by the formation of p-n junction material.
