Compare with prior art, the utlity model has following advantage:

1, energy-conservation: as to adopt light emitting diode, significantly improve luminous efficiency, replaced traditional tungsten filament, avoided because the energy consumption of generating heat and producing, thereby reached the effect of carbon reduction.

2, environmental protection: light emitting diode is installed, is not had unnecessary circuit and auxiliary product in the whole erection process, the lamp body harmful substance of yet can not volatilizing can not produce any influence to environment, meets the environmental protection purpose.

3, stable performance: adopt low compression set current technique, safe in utilization, stable performance.

4, easy to use: as to adopt the lamp holder of main flow on the market, directly apply in the various common lamp sockets.

5, option is convenient: can select collocation according to client's needs, can select dissimilar LED lamps.

6, safety: do not had traditional glass outer cover, the antidetonation coefficient improves greatly, does not worry having broken to the influence of environment and personnel's injury.
