Q:27 square female clothing store need how many LED lights

On each side to install 4, 12 w track light mist tube lamp door position 3, 5-7 w tube lamp middle or ceiling of 5 to 7 w around 3-5. Had better choose the lamps and lanterns of LED high color rendering index, Ra > more than 85. The colour of this dress is more realistic.

Q:How much time LED lamp life

In general, LED the theory of life over 100000 hours, but the LED on the power requirement is strict, the LED lamp is not can be directly to the civil 220 v power supply, there must be a special power supply first, so the service life of LED lamp is the power supply and LED a common life

Q:What's the reason why LED lamp explosion?

The LED is a semiconductor products, semiconductor components how to fry, you first take a look at what is inside shoot the light structure, what of? LED lamp is the low voltage dc power supply, so there is a 220 v low voltage transformer, rectifier, regulator, etc, so easy to explosive components only capacitance. Light not bright, then is a problem with my line, not LED lights out of the question, you think about it, four straight LED lamp is not bright, it happens only line out of the question. 1. You check the dc voltage in a circuit is big (a big will burn out the LED voltage); Check if there is no failure to press 2 points; 2. Did you check the rectifier voltage regulator internal burned components (including capacitor); To eliminate the transformer in the 【 some lamps and lanterns, to step down with other components, if one element is broken (short circuit), it is possible to high-pressure came in." 3. You're not short circuit has been measured using a multimeter, you is which part of the test? You didn't speak clearly. Dc voltage test have no? How many volts? 4. There is another reason is that the power supply voltage stability where you live? Have 220 v voltage fluctuations, especially at night, usually higher voltage (more than 220 v), if the voltage rises to more than your pressure limit of lamps and lanterns, lamps and lanterns will burn out. 5. Etc.

Q:How to adjust the light in the home

The lamp shade and light body 1. LED shoot the light of the lamp body and face mask. The best LED lamp body material for ceramic, so that the heat generated by the light of LED lamps and lanterns is able to even send out pass out, ensure the LED lamps and lanterns in the use fixed number of year is not easy because of excessive heat cause the damage of lamps and lanterns. 2. Shoot the mask on his light color, light efficiency and energy consumption on the transmission of light, choose a good material of LED to shoot the light, how to do? See his mask the light light slabs to discover whether the light to shoot the light even, if there is a splash screen. I personally think that mask with ceramic material now is best, heat conduction ability is strong, very suitable for family use

Q:The LED is low voltage and high pressure

Don't blindly pick, check whether it is capacitance step-down circuit. If it is not low pressure directly is burned out

Q:LED tube light, downlight, and what is the difference between tube lamp?

Canister light Tube light is usually a screw lamp holder, can be fitted with incandescent lamp or the lamps and lanterns of energy-saving lamp directly. Tube light is a kind of embedded in the ceiling light beam type of lighting lamps and lanterns. The biggest characteristic of it is that it can keep building decoration of the overall unity and perfect, will not damage because the set of lamps and lanterns of the art of condole top perfect and unified. The embedded within the ceiling of sex of lamps and lanterns, all light downward projection, belong to the direct light distribution. Can use different reflector, lenses, shutters, light bulbs, to obtain different light effect. Canister light do not occupy a space, can increase the softness of the space, if want to build warm feeling, can try to dress more tube lamp, reduce the space oppressive feeling. Commonly used in hotel, family, coffee shop.

Q:Cob lamp and led lamp that electricity consumption big?

Cod to shoot the light electricity consumption. Cob lamp is to use the cob LED light source as a light source to shoot the light. Traditional lamp light source used more halogen lamp and high power led, halogen lamp luminous efficiency is lower, more power consumption and environment temperature rise by illuminate, service life is short; And local too light efficiency, high power led light spot uneven, with the dark. In LED luminous principle, energy-saving, environmental protection level are much better than traditional lighting products. And LED the unidirectional formed to shoot the light distribution of the perfect support.

Q:Shoot the light and tube light have what distinction, that is better?

Many people may think the LED downlight and LED lamp is are used for household lighting should belong to the same kind product, home before decorate also have been so understanding, but in fact are not. What is the difference between between them, to introduce here. Who usually can be from both the position and application effect.

Q:The original old how long pole to shoot the light to LED lights

The assembly Electronic transformer is fixed on the original position of lamps and lanterns, two output connecting line respectively with that of the original lamp socket is linked together, good insulation and voltage polarity on the socket, and then do the LED board according to the polarity insert inside the lamp holder, even a good power cord. Check the wiring and correct after insert the 220 v power source, the light, each with 10 v voltage measurement resistance pressure drop, use the formula I = U/R calculated through the current of each group of LED lights, as long as no more than 20 ma.

Q:LED to shoot the light, heat sink, aluminum alloy profiles and die casting aluminum radiator which is better?

Even better aluminum profile, material, wall thickness can be thinner, heat dissipation performance is better..
