The basic type of LED panel light

     Now there are LED panel lights for sale in many lighting markets, many people is not strange to it,but about the basic type of LED panel light, know people may rarely.
     LED energy saving lamp is made of cap type small power LED, power supply adopts a resistance capacitance step-down circuit. The cap type LED using package way of LED indicator, the epoxy resin package, so that the LED chip can not heat, light attenuation serious. Many white LED, after a period of use, the color temperature rises, gradually turned into bluish color, become dim. This kind of LED panel light is transitional products, the price is low, quality is poor.
     LED panel light is made of medium power LED, power supply generally use a resistance capacitance step-down circuit, some led light panel manufacturers to adopt constant current circuit, the heat dissipation capability of SMD LED is better than cap type LED, have a heat conducting substrate, with the aluminum substrate, a part of heat can be conducted away.
     LED panel light is made of high power chip LED, the power supply is generally adopts constant current isolation circuit, which has a constant current, such as 5W LED, usually by 5 pieces of 1 watt LED chip, series connection, using a constant current supply of 300mA, wide voltage power supply. When the voltage fluctuation, the current did not change, the brightness will not change. 5 pieces of SMD LED is welded on the aluminum substrate, aluminum plate combined with on the radiator, the heat can be rapidly dispersing when using, ensure the LED chip temperature is lower than LED allows temperature, so as to ensure real and effective life of LED panel light. This kind of LED panel lamp price is high, the quality is good, this is also the development direction of LED panel light.

The difference of LED track spot light on the price

    The low price LED track light and high price LED track light has several obvious difference:
    1. The difference of workmanship. The low price LED track spot light workmanship slightly rough, from the outside can see;
    2. The power is difference. The LED lamp power is greater, the higher the price; because of its price and the number of LED chips, driver power supply quality, radiating shell quality have a great relationship;
    3. Material is difference. The low price LED track light material is relatively poor. A LED track light is composed of lamp shell, power supply, LED chip etc., the whole lamp heat radiation and appearance decided by lamp housing. The power failure rate is the highest, so the LED track light the same power, its price is affected by the influence of the power supply. LED chip decided the light color is pure, has a certain effect on the light gather (LED chip with vertical light and side light, use LED chip of vertical light emitting to make lamps will have a better light spot). Fault LED chip rate is very low, but the current high prices and low price of the track lights, the LED chip price is also very obvious, there is usually 1-3 times difference.
    4. Each LED lamp manufacturers of after-sales services are different.

Which factors determine the LED bulbs price

     LED lighting industry in today's increasingly fierce competition, some manufacturers have launched a price war. In the market, appearance, structure and function of almost the same product, the price difference is 2-3 times, most consumers know the reason, unless the professional manufacturer, it is generally difficult to distinguish.
     What's causes the different of LED bulbs price?
     1, brightness.
LED bulbs use LED light source of different brightness, the price is different.
     2, lifetime is different.
Lifetime is decided by the light fades. Light a small decline, long life, high price.
     3, antistatic ability.
     Antistatic ability of LED bulb is strong, the life is long, thus the high price. Anti static than 700V LED can be used for LED lamp.
     4, the wavelength.
     The same wavelength LED, the color is same, such as requiring the same color, the price is high. No LED spectrophotometric color instrument manufacturer is very difficult to produce pure color products.
     5, the LED chip.
     LED bulb luminous body is chip, different chips, prices vary widely. Japan, the United States more expensive chips, Taiwan plant with China's domestic manufacturers of LED chip prices lower than Japan, the United States.
     6, the chip size.
The quality of big chip LED is better than small chip LED. The price is high.
     7, the leakage current.
     LED is a one-way conductive light, if there is reverse current is called leakage, the leakage current is large, short life, low prices.
     8, the light emitting angle.
     Different uses LED light emission angle is not the same. Special light angle, the higher the price. If all diffusion angle, higher prices.
     9, colloid.
     Ordinary LED colloidal is epoxy resin, have anti-UV and fire retardant of LED, the higher the price, high-quality outdoor LED lighting should be UV and fire.

What is the LED trunk light

     In the development process of the lamp, in order to fit people's aesthetic, so the appearance of different kinds of lighting also will produce, trunk light is one of the classic. LED trunk light is an embedded LED ceiling light. It looks like the trunk, so called trunk light.
     Trunk light are usually is used as a spotlight, it applies to clothing stores, home stores, jewelry stores, professional windows, counters, all kinds of exhibition halls and other places need to focus on lighting. It is the ideal lamp to replace traditional halogen tungsten lamp and metal halide lamp.
     Trunk ceiling light working environment temperature is generally -30 ℃ ~ 50 ℃, the input voltage is generally: AC90~260V, up to 50,000 hours life.
     Adjustable angle of the LED trunk light is more flexible and convenient than the conventional embedded spotlight. It uses wide range adjusting design (universal regulation), the horizontal direction is 360 degree, the vertical direction is 50 degree, so the light without any waste, to ensure maximum effectiveness of lighting.
     LED trunk light using anti glare design of the light-emitting surface invagination. The external structure is more high-grade than conventional embedded spotlight, meet the needs of the majority of the high-grade malls.

What is the LED track light

     Track lamp is installed in a similar track, can arbitrarily adjust the irradiation angle, generally used in the need to focus on lighting places. So what is the LED track light? How does it work?
     LED track light is to LED as a light source for track lamp. The same as the traditional track light, need to install in matching the tracks, there is voltage input in the track inside.
     On both sides of the rail internal with conductive metal strip (high quality track made of copper, poor quality track made of iron), and the track lamp joint have a conductive copper sheet can be rotated. During installation, the LED track spot light conductive copper sheet contact to the track conductive metal strip, track light will be energized, track lamp was lit.
     Now, LED technology is gradually mature,track light from the previous metal halide light source was gradually replaced by the LED light source, thereby achieving more energy-saving, environmental protection. now people usually say track lights , slowly collectively referred to as the LED track light.
