FAQ

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
The same power of cob and led lamp which is brighter
General use Taiwan chip COB light efficiency: 65 ~ 80 lm/W, the greater the power light efficiency is lower.
The led lamp is suitable for reading?
You can replace a led fluorescent lamp, it is better on the eyes!
The led lamp or built-in good external constant current driver
In terms of the whole lamp, a light source, a power supply are heating element, temperature rise overlay, if put together lead to the accelerated ageing of the LED light failure seriously affect the life
LED track lamp series and LED lamp series, what's the difference?
Shoot the light is mainly refers to a lens, have concentrated effect, such as lamp cup, ceiling lamp, project-light lamp. Corresponding floodlight, such as tube lamp, solar tube, lamp shade with diffusion function
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.
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
Smallpox lamp is max25w LED power rating, is 25 watts
Max25w here is probably equivalent to a 25 w incandescent lamp brightness is 3-5 w power consumption
