LED bulb is to use high brightness white LED light source, high luminous efficiency, less power consumption, long life, easy to control, no need maintenance, safe and environmental protection, which is a new generation of solid cold light source. Compared with the tube type bulb, the LED bulb is more save electricity, higher brightness, light more far and LED bulb's cast light performance is better, the use of voltage range is wider, the light source can realize the LED seven color change by microcomputer built-in controller, which is soft, bright color and rich color. LED bulbs are low loss, low energy consumption, green environmental protection, which are suitable for family, shopping malls, Banks, hospitals, hotels and varieties public places.

Compared with the incandescent lamp tube or fluorescent tube, LED bulb is more stable and service longer life. Incandescent bulbs' work time rarely continuous more than 1000 hours. The continuous working time of fluorescent tube by electronic drives can be more than 8000 hours, and the LED bulbs continuous working time can be 50000 hours.

The features of LED bulbs as follows:

1.High efficiency and energy saving: Only consumes a few degrees in one thousand hours, 60W ordinary incandescent bulb consumes 1 KWH in 17 hours, 10W energy saving bulb spent 1 KWH in 100 hours.

2.Longer service life: Long life: a semiconductor chip, no filament, no glass bulb, not afraid of vibration, nonbreakable, service life can be up to fifty thousand hours, ordinary incandescent bulb only has one thousand hours service life, the service life of the ordinary energy-saving bulb is only eight thousand hours.

3.Health: no ultraviolet and infrared light, the light does not produce radiation (normal lighting ray contains ultraviolet and infrared);

4.Green environmental protection: no mercury and xenon harmful elements, it can be recycling, and won't produce electromagnetic interference (the ordinary bulbs contain elements such as mercury and lead, electronic ballast of energy-saving lamps will produce electromagnetic interference);

5.Protect eyesight: dc drive, no stroboscopic (ordinary light is ac drives, is bound to produce stroboscopic);

6.High light efficiency: 90% electricity converted into visible light (ordinary incandescent bulbs 80% of electrical energy converted into heat energy, only 20% of electrical energy converted into light energy);

7.High safety factor: the required voltage and current is small, small heat, it dose not produce safe hidden trouble in dangerous places;

8.Market potential is great: low voltage, dc power supply, battery, solar power supply, can be used in remote mountainous areas and outdoor lighting and other places of power shortage, less electricity.
