Q:As title, please the personage inside course of study to explain to shoot the light and PAR light some of the differences in structure and application fields, especially for the requirement of power supply. Thank you very much!

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. PAR lights (Parabolic Aluminum Reflector light), which is also called, canister light, its structure is also useful in specular light bulbs installed in the cylinder reflective bowl of bromine tungsten bubble, main feature is that penetrate the fixed beam, beam Angle width of light spot size can adjust

Q:Tube lamp, metal halide lamp, lamp, LED lamp, the difference between more than advice please!

Tube light is used for general lighting, can use energy-saving lamps and LED lights Metal halide lamp together not concentrated mostly see shape, but the metal halide lamp used for local lighting effect is very good, like a clothing store Than metal halide light that shoots the light is weak, but stronger than canister light LED just refers to the light source, with energy-saving lamps, incandescent light bulb is a concept

Q:The same power of cob and led lamp which is brighter

Taiwan chip is commonly used in single chip LED photosynthetic efficiency (commonly known as the single lamp) : 80 ~ 110 lm/W, under the same power chip, the greater the size (area) the higher light efficiency.

Q:Led12V3W's radio lamp is ac or dc

Dc. LED lights, scientific name is light-emitting diodes (leds), are the dc. led12V3W Means, 3 w power leds, power supply is 12 v dc supply. Is answered.

Q:The led lamp or built-in good external constant current driver

Good, external device is greater than the space without limit, you can do better, and the other heat dissipation is better, longer service life.

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:What about a three-male led light?

In general. Mitsuo main strengths is the electronic ballast and match the lamp panel stent engineering lighting products. Led is given priority to with light matching a variety of lamps and lanterns, heat dissipation problem. Personal opinion. Hope to help you answer.

Q:The difference between the LED downlight and LED lamp

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. On the second place in application to distinguish: LED tube lights are mostly installed in the ceiling, above ceiling to 150 mm is required to install. Of course, there are LED tube light is of the external type. General selection in the absence of the location of the dome light or droplight to install the LED tube light, the light is slightly softer than shoot the light. The LED lamp can be divided into several categories: type, hanging and embedded, etc. To shoot the light is divided into with transformer and without transformer. That belongs to the embedded in the ceiling.

Q:What is the difference between led track lamp and led lamp? Search the hotel guest room can be used?

Orbital lamp belongs to shoot the lamp to be one of the products. LED track lamp is guiding light, belongs to the accent lighting lamps and lanterns of a commercial lighting product type.

Q:Store decoration, good track shoot the lamp to LED lamp or metal halide lamp is good?

LED lights. LED lamp is more energy efficient, longer life, and light failure is small.
