Described transparent lamp shade is the explosion-proof safety glass lampshade of printing opacity.

Described Drive and Control Circuit plate is connected lamp body by lead, and circuit board (10) is drawn by the place, hole by lead, is placed on the position away from focus.

The utility model is the light LED lighting source of solid encapsulation, the utility model compared with prior art, its advantage is as follows:

1, luminous efficiency of source height, economize on electricity are significantly: the high-power LED illuminating lamp light efficiency can reach 80-120lm/W at least, and theory is 250lm/W.Compare with the incandescent lamp with brightness, high-power LED illuminating lamp can be saved the 75-90% electric energy, and service cable line footpath also can reduce greatly.

2, light source long service life: because of it adopts large-scale fin heat radiation, can make led light source keep unattenuated for a long time, the life-span surpasses 50,000 hours, and theory can reach 100,000 hours.

3, stable, the no stroboscopic effect of luminous flux: the utility model high-power LED illuminating lamp is to adopt constant current driven, does not produce any stroboscopic.

4, shockproof properties is strong: the light source of the utility model high-power LED illuminating lamp adopts solid encapsulation, each contact portion all installs rubber sheet gasket or spring washer additional, light source and the design of Drive and Control Circuit plate separate type, Drive and Control Circuit can be placed on the place away from focus, has better strengthened the shockproof properties of this illuminating lamp.

The utlity model has that volume is little, in light weight, the characteristics of good directionality, damp proof moisture resistance, high-strength anti-shock, can be adapted to various mal-conditions, at aspects such as antidetonation, power consumption, life-span and environmental protection incomparable superiority is arranged all, be enough to enormous impact is caused in traditional engineering lighting source market.Along with the breakthrough of third generation semi-conducting material, the LED illuminations is replace incandescent and fluorescent lamp progressively, becomes the main product of illuminating industry, more can be applied to the explosion-proof antidetonation of engineering on a large scale.
