Said through hole is circular hole, square hole, elliptical aperture or irregularly shaped hole.
The madial wall of said heat dissipation channel is provided with reinforcement.
Between said loam cake and driver, also comprise a transition disc, the position of corresponding loam cake through hole offers through hole on the said transition disc.
The through hole that the correspondence position of said loam cake, transition disc and radiator is offered is meant extended tubular structure; The tubular structure that covers wherein inserts or is enclosed within the tubular structure upper end of transition disc; The tubular structure upper end of radiator is inserted or is enclosed within the tubular structure lower end of transition disc, and the tubular structure junction of loam cake, transition disc, radiator and the installation junction of these three parts are provided with O-ring seal.
Said dividing plate upper surface installation of driver, said driver is installed in the tubular structure upper end of avoiding radiator.
Said dividing plate upper surface installation of driver, said driver offers through hole on the position of corresponding led light source plate through hole, and the tubular structure upper end of said radiator passes from said driver through hole, inserts in the tubular structure lower end of said transition disc.
Said radiator periphery is provided with radiation tooth; Inside is cavity; One dividing plate is set in the cavity; The led light source plate is installed in the dividing plate lower surface, and dividing plate offers through hole on the position of corresponding led light source plate through hole, and the tubular structure lower end of said radiator passes from the through hole of said dividing plate and led light source plate.
Said led light source plate is provided with integrated lens module, and lens module offers through hole on the position of corresponding led light source plate through hole, and the tubular structure lower end of said radiator passes from the through hole of said lens module.
The tubular structure lower end of said radiator extends to the diffuser place, and joins with colloid between the through hole of diffuser correspondence position.
The beneficial effect that the utility model technical scheme is brought is following:
Explosion-proof lamp is because degree of protection requires than higher, and the sealing of generally on structural design, all trying one's best must all be enclosed in enclosure interior with all optics and electricity components and parts.Because LED and power supply driver can all can produce great amount of heat in the course of the work; This closed structure must make all heats all be enclosed in lamp interior; Only can not effectively solve the heat divergence problem of gathering, be easy to cause light fixture to burn out even the danger of the incidents of blasting through the outside heat loss through radiation of housing.The utility model technical scheme adopts a heat dissipation channel that runs through whole light fixture front and back is set; Similar one " chimney " be installed on light fixture; " chimney " has very strong ventilation, exhausting effect, forms heat loss through convection with the external world, thereby can improve the radiating efficiency of light fixture greatly.
