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?

Save electricity, and so you explain: for example, if you use 400 w street light before now open for eight hours a day, a month's worth of electricity is: 30 = 96 * 400 * 8 * 1 1 yuan (electricity) = 96 pieces and LED120W lamps can reach 400 w the same brightness, a month's worth of electricity is: 28.8 degrees 30 = 120 * 8 * * 1 1 yuan (electricity) = 28.8-28.8 = 67.2 96 blocks of a lamp can you make a month to save 67.2 piece of this is to save electricity! More than just... probably not very accurate

Q:LED two head lamp lines do not short circuit is not grounded on the total trip what reason?

Should be a short circuit, first down to shoot the light, open switch, if can open, is lamp short circuit, if not is the line short circuit!

Q:Does the LED light have to be transformer?

It's not called transformer. LED lights need drive power, has permanently flow drive and resistance capacity drive, usually 220 v50hz ac power input.

Q:Sitting room condole top round with tube lamp or LED lamp good?

If simply on the role of lighting with leds, more energy efficient, but cost is higher (actually a year to save electricity I guess there isn't much, psychological effect is greater than the actual role). Canister light that individual is not very recommend, general tube lamp light source is energy-saving lamps, looks uncomfortable

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:Home use shoot the lamp to general how many watts is the best?

1, energy conservation: the same power of LED lamp power consumption is only 10% of incandescent lamp, energy saving than fluorescent lamp. 2, long service life: LED lamp bead can work 50000 hours, longer than fluorescent lamp and incandescent lamp. 3, adjustable light: previous dimmers has always been for incandescent lamp, incandescent lamp dimming the light is red. It's hard to see fluorescent lamp dimmers, this is dimming technology for many years the main reason for no development; Leds can move light again, and both light and dark are all the same color (color temperature constant), it is better than incandescent dimmer. 4, can be frequently switch: LED life is calculate by when lit, even if the switch is thousands of times per second also does not affect the LED life, in the frequent need to kill bright occasions such as adornment, leds have absolute advantage. 5, color is rich, is white, warm white light, colors such as red, green, blue, whether it is in the living room beside the headlight small lights or neon lights for ornament, is very bright. 6, low calorific value, like to shoot the light, a lot of 220 v incandescent lamp with not a few days is broken because of fever. 12 v halogen lamp calorific value is lower than 220 v to shoot the light, but there is another due to the lack of power distribution transformer, its brightness than the nominal value. Use LED lamp, no transformer can work long hours.

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:How to distinguish the LED lamp wattage, such as the 12 piece is how many watts

LED lamp sometimes measured, if not, is difficult to know the real wattage, 5 of the lamp bead, such as single atom 1 w the lamp is 5 w, generally but the lumens is not the same, the same number of lamp bead, the same wattage, brightness is different, this time, may be on the surface of the intensity of illumination blinded his eyes

Q:Led lamp and cob light which is suitable for hanging the sitting room

Domestic outfit may generally don't have to shoot the light Generally canister light is good Decorate need lamps and lanterns can look for me I do wholesale of lamps and lanterns of home outfit have a lot of money

Q:Ordinary household lighting (building), just connected the light is bright, is a little dark light, the switch is closed, I tried to take lamp to another building, light is no problem, family line which place is wrong?

Switch to the zero line, should be a wire into the switch, do you have the leakage floor on a line, so it caused the leakage current, the LED can shed light on small electricity.
