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:The difference between floodlight and LED to shoot the light

Hello!!!!! Waterproof, omni can be waterproof, but it is difficult to do waterproof shoots the practicability, floodlight used outdoors, but shoot the lamp to be more used for indoor power size, floodlight can reach the maximum power of far distance is much bigger than that shoots the light projection, omni range than shoot the light

Q:LED to shoot the light flashing or not on how to deal with?

You use multimeter to play your first whether the voltage stability?

Q:LED to shoot the light is not very bright, or where the flash is broken?

Two questions inside shoot the lamp to lamp bead is leakage can be determined, at first, no flash is used less, use a long time, and with the leakage of electric lamp bead, commonly known as the internal short circuit, affect the driver's working status and life, lamp bead brightness is not enough, is the droop, lamp bead is not good, the greater the droop. Suggest you to return to the manufacturer, or manufacturers a replacement.

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 the difference between led track lamp and led lamp? Search the hotel guest room can be used?

Search track shoot the lamp to be suitable for all kinds of needed light rendering, focused on the interior space environment lighting, widely used in museums, libraries, commercial shops, hotels, clubs, catering, professional venues and other indoor places, LED track lamp do better at present domestic brand with philips, thorne, WAC lighting, panasonic, leishi, ty, the big room, sidon, opple, mitsuo aurora, kei, lighting, TCL lighting, etc. Hotel customers use less LED to shoot the light, usually adopts embedded LED lamp or ceiling lamp, canister light, etc.

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

Transform the power The lamp is with electronic transformer is 220 V / 50 hz ac DianZhuan into 12 V high frequency alternating current (ac) for the use of shoot the light, for the LED power supply. Now should be high frequency ac DianZhuan into 12 V dc 12 V, so that power can be multiple groups of three series of LED lights (in terms of each only 3.5 V), each lamp visible need more groups in parallel, in order to reach a certain brightness. To add a high-frequency electronic transformer rectifier filter circuit, it can be high frequency ac DianZhuan into 12 v dc 12 v. Rectifier with high-frequency rectifier tube, HFC L can use energy-saving lamps of the circular on the glass with plastic envelope around 10 turns the substitution. Cut a small piece of PCB on the above components on the electronic transformer, after connected with insulated wires - and into electronic transformer molded case, output leads to +, - two power supply line.

Q:The classification of the LED lights

This should call canister light, shoot the light is with lens and PAR lights a category, you only send positive figure I guess should die cone on the back

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

Should be low voltage halogen lamp bead lamp, shoot out the effect of this type is the best temporarily, but a fever, power consumption is big, easy to bad. Most people are now switching to LED, the effect were similar, but the disadvantages of halogen lights, LED all have no.

Q:The led lamp is necessary to use good

Household LED must choose good, because now the LED quality too, with the bad LED to the injury of the eyes is very big
