It carbide as the filament,

 It carbide as the filament, is a huge improvement in lighting technology, in 1938 invented the   LED Downlight  fluorescent lamp (otherwise known as fluorescent lamps, Fluorescent Lamp) can reduce heat loss and save energy consumption , this is a big step forward, then compact fluorescent lamps (Compact Florescent Lamp) make application development more generally, while high-pressure gas discharge (HID: High Intensity Discharge) lamps,

 such as mercury (Mercury Lamp), metal halide (Metal Halide Lamp) and sodium (Sodium Lamp), etc. invention may be implemented in the outdoor lighting, to meet the various needs. At present, about 21% of the power used for lighting, if you can save half of the field of solid-state lighting energy, the effects on human energy savings make a huge contribution. LED Strip

    Using semiconductor materials (Semiconducting Meterial) made red, yellow and green light emitting diode (LED: Light Emitting Diode) has been successfully developed about a decade ago, most of these LED AlInGaP material made with, but until a few years ago, Material success is made with AlGaInN blue LED, white LED's dream was that that eventually became a reality. The  GU10 semiconductor material is called white LED solid-state lighting (Solid State Lighting), a light source will be described below before the performance.
