Q:Led to shoot the light, the 12 v transformer and transformer can general ordinary lamp?

Can't, because leds points of positive and negative polarity (dc), and ordinary lamp general both (ac). If money does not can be connected to use after rectifying, pay attention to the polarity.

Q:Led lamp can use ordinary incandescent dimmers adjust brightness.

LED to shoot the light, what do you mean low voltage 12 v or 230 v? If it is 12 v, with light dimmer is not enough, want to be in circuit transformer, otherwise it will burn. Instant connections, estimates that 99% is not enough, because want to let the LED MR16, MR11 shoot the light and the combination of dimmers + transformer matching without flashing, is a technical difficulties, and the head of the LED light source manufacturer will publish a and LED lamp dimmer and transformer matching brands, types and models of CRT, want to match all 100%, in the present on the earth is not human can do, see later, (want Daniel)

Q:Decorate the house, to shoot the light tube light a matter of choice

6 3 w warm white LED lamp; Lamp with choose warm white LED lamp belt, best to shoot the light, and light with choose the same product. 2, choose 1 bedroom wled3 shoot the light, only warm white. 3, 2 only 1 second lie wled warm white lamp; Desk choose 5 wled warm white tube light. 4, toilet choose 5 w, warm white LED tube light.

Q:Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad

Lights, namely the number of lumens per watt, LM/W, he reflects the energy-saving performance of lamps and lanterns, power saving, the more good lamps and lanterns, the higher light efficiency. Current leds and compact fluorescent lamps and lighting, with the improvement of LED lights, CREE possible amount of output this year 186 lm/w illuminant. Cash supply high power DC - DC DC converter, DC booster, 36, 48 v/v / 60 v electric inverter, electric vehicle intelligent DC converter. 24 v - 72 v electric vehicle controller, etc...

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 is negative would pick up the light damage?

How much driving voltage rating? Series number for how many leds, partial pressure of each

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

42 v only do as much as 14 w, this is the most basic request, if I see this kind of drive is absolutely can't use, because the basic common sense all wrong, quality), the voltage is not enough, so is certainly not the light, do you want to buy a maximum output voltage at least 54 v drive

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:What is main purpose of the LED lamp

Save electricity saving life is long Art effect is good The light is downy healthy variety does not hurt eyes

Q:Why home outfit LED lamp has always been a bit weak after switch off the light

Is the new LED lights! Inside capacitor discharge as a normal, suggest you use unplug after will disappear in a few minutes.
