By
study on the Characteristics of large-power LED illuminant,it put
forward some technical roadblocks in application of mining explosion
proof lights with LED illuminant and the solutions to these problems in
existence conditions.It is concluded that an explosion-proof light
should be equipped with a suitable LED illuminant according to different
types of the light,thus,the domination property of LED
illuminant,including long lifetime,energy conservation and safe can be
performed.In this sense,To select rational LED illuminant is the
solutions to these roadblocks in the application of LED illuminant in Ex
luminaries.Meanwhile,some suggestions have been provided for the user
to select proper luminaries,to ensure the safe
