Anti-explosion light-emitting diode (LED) energy saving lamp used under severe environment

The invention relates to the field of photoelectric technologies, in particular to an anti-explosion light-emitting diode (LED) energy saving lamp used under the severe environment. The LED energy saving lamp comprises a facula correction free-form surface lens, a high-power LED, a circuit board, a radiating structure, a casing mask and a casing and is characterized in that an active area laminating material of the high-power LED is A10.1GaO.9N with the thickness as 6nm, A10.15GaO.85N with the thickness as 7nm and A10.1GaO.9N with the thickness as 7nm. An upper limit layer and a lower limit layer are respectively p type A10.1GaO.9N and n type A10.1GaO.9N, the doping concentration of the p type A10.1GaO.9N is 1*1018cm , and the doping concentration of the n type is 4*1017cm . A p type doping agent is DEzn, and an n type doping agent is 2%BF3. The LED energy saving lamp is characterized in that light source selectivity and casing mask light transmittance ensure that the light can penetrate steam, haze and the like under the severe environment. The LED energy saving lamp has a good lighting effect, has an anti-explosion function and has good application prospects.
