What are the disadvantages of LED bulb

     The LED bulb have the advantages of energy saving and environmental protection, so the LED bulb is becoming more and more popular. But the LED bulb is also not be the pink of perfection. What are the disadvantages of LED bulb?
     The disadvantage of LED bulb is mainly reflected in the price. The performance is better, the higher the price. Because LED bulb complex in structure than incandescent, even in the case of mass production, the price will be higher than incandescent lamps. Currently, the price of LED bulb is also higher than the electronic energy-saving lamps. But with the LED bulb are more and more people understand and accept, and gradually expand the scale of production, the LED bulbs price will soon reach the level of electronic energy-saving lamps. At the time of purchase if you calculate the charge, and you will find, even now LED bulbs price is higher, on the basis of one year, based on the initial purchase cost plus a year electricity bill is lower than incandescent and electronic energy-saving lamps. And the LED bulb can now have up to 30,000 hours life.

What are the advantages of LED track light

    LED track light is a track lamp, its light source with LED. It is widely used in key lighting places, such as shopping malls (clothing stores, furniture stores and other brand stores), car show, jewelry, Stars Hotel, brand clothing, high-grade club,  museums, chain stores, brand business hall, professional window, counter and so on. It's the ideal light source to replace traditional halogen tungsten lamp and metal halide lamp. With the development of electronic technology, the emergence of many new styles, various shapes, flexible and changeable.
    The advantages of LED track light:
    1, LED track light is with LED as light source. LED light source is a cold light source, no radiation, no heavy metal pollution, pure color, high luminous efficiency, low frequency flash, energy-saving health. The light source of ordinary metal halide track lamp is metal halide lamp, the luminous principle of metal halide lamps are Mercury is after gasification and the two electrode reaction that produces light, will produce a lot of heat and radiation, and if it's broken must be handled with care, otherwise may pollute the environment (mercury is a heavy metal elements, harmful to human health).
    2, A typical characteristic of LED track spot light is energy, LED track light and metal halide track light at the same brightness, the power consumption of LED track light is only the ordinary metal halide track light 40%-60%, obviously the power saving effect.
    3, High quality LED track light life of at least 30000 hours, while the life of an ordinary metal halide track light is generally 8000 hours, between them the difference is very obvious in life.

The benefits of LED light tube

     LED fluorescent light with traditional fluorescent light alike in appearance size caliber. Length is 60cm or 120cm or 150cm, the power respectively 10W, 16W and 20W. 18W traditional fluorescent lamps (ballast) actual power consumption is about 26W, 36W the traditional fluorescent lamps (ballast) actual power consumption is about 45W.
     Compared to conventional fluorescent lamps, the benefits of LED light tube are as follows:
     The effect of energy saving: 10W LED fluorescent lamp brightness than the traditional 40W fluorescent lamp is brighter and 16W LED fluorescent light than traditional 64W fluorescent lamp will light, LED light tube brightness is softer, making it easier for people to accept. The service life at 50000 -80000 hours, power supply voltage of AC85V-260V, without qihuiqi and ballast, start fast, small power, no stroboscopic, not easy to visual fatigue. It is not only a super energy-saving, more environmental protection. These advantages of LED tube, so it becomes one of the focuses on the development of lighting engineering products of national green energy, is the main product to replace the traditional fluorescent lamp.

The color temperature adjustable led bulb light profile

     The color temperature adjustable led bulb light including a plurality of LED devices and controls the LED drive control device module. LED devices are LED devices with different color temperature, and based on the color temperature of the LED devices were divided into several groups. The drive control module controls the LED device of each group, one or more sets of the light-emitting light.
     The drive control module of the color temperature adjustable led bulb light includes LED dimming control circuit, where there are multiple color temperature control switch, each color temperature control switch connected to a set of LED devices group, used to control the current on-off of LED device group.
     This LED bulb driver circuit further comprises a power supply control module and a first micro-processing unit. A first output terminal of the power supply circuit is connected to LED dimming control circuit input terminal by the power control switch. A second output terminal of the power supply circuit is connected to the input terminal of the first micro-processing unit. The first PWM control signal micro processing unit connected to the output terminal of the power supply control switch for controlling the on-off state of the power control switch. The color temperature control signal output terminal of the first micro-processing unit circuit is connected to LED dimming control signal input terminal circuit are connected, used to control the color temperature control switch on-off.
