Q:What is a good material of led tube light

Bulb matching can be divided into: there are 2700 k (yellow), and 4000 k (neutral light), 6700 (k) (white), three types of the three kinds of color temperature can create a different atmosphere. According to the different color collocation gives the perfect purpose to choose the most appropriate color lamp. There are two kinds of the direction of lamps and lanterns, if at the top of the space is enough big, directly buy shaft plug, if at the top of the space is little, not enough distance, can consider to flat type, the price gap is not big.

Q:Led lamp have drive, don't drive, what's the difference?

In theory does not need to drive, direct input 220 v LED lamps and lanterns of longer life, but at the moment, the corresponding technology is still not perfect, than higher prices, there are still some problems So now can still need to drive leds You want to know what LED lights

Q:LED lamp with drive, do you want the transformer?

There are two kinds of leds to shoot the light, the 12 v power supply voltage and 220 v power supply voltage. If the power supply voltage is 220 v, without additional transformer, lamp has a built-in transformer. If it is a 12 v power supply, need another 12 v power supply, general ac dc, but never can directly connect the 220 v power supply.

Q:How to differentiate between canister light shoots the halogen lamps Bean pot lamp LED lights

Inside the tube light can be filled with energy-saving lamps, incandescent bulbs (lighting, light relatively concentrated) Shoot the lamp to shoot the light cup (decorative light that targeted) Halogen lamps, incandescent light bulbs in mixed with gas halogen element, working principle is: when the hot filament, tungsten atoms are moving in the direction of the glass wall after evaporation, when close to the glass wall, tungsten vapour is cooled to about 800 ℃ and halogen atoms together, form a tungsten halogen tungsten (iodine tungsten or bromide). Tungsten halogen continues to move up to the central tube, is back by oxidation of filament, because halogenate tungsten is a very unstable compounds, again after the encounter heat into steam and tungsten halogen, tungsten and deposited on the filament, make up for the evaporated parts. Through the recycling process, the service life of heater not only got significantly longer (is almost four times that of incandescent lamp), at the same time because of the filament can work at higher temperatures, resulting in a higher brightness, higher color moderate higher luminous efficiency. Dared light: light source of lamps and lanterns of the tank to look like a bucket shape, has 2, 3... Led lamp is energy-saving lamps which we said

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:Led courtyard lamp long good or single head

The upstairs to answer very professional. Lamp holder, the more the better, the single head can't be used if it is broken, the bulls' bad a lighting effect, and long heat dissipation is better than single head (this is important!) .

Q:LED lamp biggest can do how many watts?

3 w. Following is the specific features of high power led lamp product. Product specification 1, working voltage: 12 v 2, working current: 700 ma high-power lamp, the maximum power: 3 w Lm, luminous flux value: 120-120 5, color temperature range: 2700-6500 k 6, light Angle: 30 degrees 7, emitting light colors: white/warm white 8, the working temperature: - 20 ℃ to + 85 ℃ 9, the shell material: aluminum alloy 10, the service life: 50000 hours High power LED lamp appropriate beauty can be divided into two kinds: one kind of relatively large total power lamp for our products. Such as PAR lamp. Another as the light source adopts high power (1 w and more than 1 w) LED to shoot the light

Q:LED to shoot the light flash when open, a period of time is normal

The LED lamp 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. LED lamp is mainly composed of shell, light bead, aluminum version of the driver

Q:How about TCL LED to shoot the light, the price is about,

Can look at other brands! Such as leishi, philips, sunshine! They use LED chips are mostly American cory and Japan, and Taiwan wafer, quality no difference! Are all working for somebody else, there is no difference!

Q:LED lamp is not lit, how repair?

90% is probably the main step-down capacitance is broken, is the middle of the big red, a dollar or so. As for the diode and the probability of electrolytic capacitor bad within 10%, the multimeter amount is known.
