PURPOSE: An explosion-proof led type lamp is provided to extend the lifespan of a product by changing the optical module of an LED using the housing and cover of the explosion-proof led type lamp. CONSTITUTION: A printed circuit board(51) has a light emitting diode and a bottom heat sink is fixed thereto. The bottom heat sink transfers partial heat to a cap(2), a housing, and a plurality of heat radiation rod. The heat rod has a concavo-convex region(541) and radiates heat to the bottom heat sink. The upper heat sink(55) transfers partial heat to the housing. |
