Q:The difference between the LED lamp

Applied position Tube light is usually thought to be installed in the ceiling, condole commonly need over 150 mm to pack. Of the canister light, of course, there are external type. In the absence of dome light or droplight installation tube light is a good choice, relative to shoot the light wants downy light. Shoot the lamp to be generally can be divided into orbit type, hanging and embedded, etc. Shoot the light with transformer, but also have without transformer. Embedded within the lamp can be installed in the ceiling. Lamp is mainly used in the need to emphasize or performance. Such as TV wall, hang a picture, accessories, etc., can play the light to enhance effect.

Q:Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?

The power of the LED lamp is using a constant current power supply, and shoot the lamp to use 12 v constant voltage power supply, the nature of the power supply is not the same, if used on the LED constant voltage power supply, will directly cause damage to the LED current is too large. Therefore, shoot the light output 12 v transformer 20 to 50 w can't be used for LED lamp.

Q:Stationary LED to shoot the light is not bright, how repair

Bad swap places after good, is the question about which line, otherwise is the problem that shoots the light

Q:Led lamp power consumption how much every day

Power consumption calculation: 1 hour because 1 kw is 1 degree, if according to the 5 w, 10 hours, computational method is, 0.005 kw x = 0.05 degrees, 10 hours a month (30 days) power consumption is 1.5 degrees.

Q:LED lamp is negative would pick up the light damage?

Of course. Especially the constant current drive leds. General LED reverse and pressure is not high.

Q:How much is five inches square led high power lamp

Shoot the light is a typical advocate the lamp, wuding scale modern genre of lighting, can create an atmosphere of indoor lighting, if a row of small shoot the light, the light can change the wonderful designs

Q:The difference between the LED downlight and LED lamp have?

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. LED lamp is embedded in the ceiling or wall, general lighting products is a kind of highly concentrated, usually it's light to the specified target position. Through light is used to emphasize important points. When working, due to the LED lamp produces high temperature, so the LED lamp when the choose and buy must choose the high quality product, otherwise it will produce safe hidden trouble. Now LED lamp is mainly used for all kinds of commercial space lighting and architectural decoration lighting, etc. At the same time to shoot the light is divided into low pressure and high pressure, proposal consumer had better choose low voltage lamp, due to low pressure lamp life relatively longer, the higher light efficiency. Shoot the light of the general lighting power factor to decide, good lamp power factor can reach 0.99, but the price is much expensive.

Q:How to distinguish the LED lamp wattage?

Look at the size of shoot the light, usually different wattage of the radiator is not the same.

Q:Clothing store, LED lamp used to burn more than a year, what's the matter

The service life of LED lamp is 100000 hours, and general tube core of this kind of lamp holder are domestic. A few minutes to a few cents, while imports of a few dollars. More than a year, is very normal. Upstairs said is very right, voltage! Input ac voltage is not stable, lead to you in the right regulated power supply output is estimated. Get a better stand, safety first.

Q:Drive power supply with a what kind of specification, can be in parallel two 3 wled shoot the light

You want to work until 3 w leds first what is the current, now that is a parallel, the output current is the sum of two current in constant current source circuit.
