Title: LED HEAD LIGHT
Abstract:
Disclosed is an LED head light, comprising a thermal conductive body (101), a cavity being provided in the thermal conductive body (101), the thermal conductive body (101) penetrating through the cavity in the front-back direction, at least two ribs (103) being provided at an end face of a front end opening of the thermal conductive body (101), all of the ribs (103) protruding outwards with respect to an axial outer wall of the thermal conductive body (101), a gap of front-back penetration being provided between all the ribs (103), an outer annular platform (104) used for connecting with a device for a light extending outside a group of ribs (103), and the group of ribs (103) being located between the outer annular platform (104) and an outer wall of a front end of the cavity; and a thermal conductive seat (102), an outer circumference of the thermal conductive seat (102) being fitted with an inner wall of the cavity in a sealed manner, a top face of the thermal conductive seat (102) being fixed with an LED light source (112), and the LED light source (112) facing towards an opening of a front end of the thermal conductive body (101). When fluid surrounding the LED head light moves backwards with respect to the LED head light, the fluid flows from the gaps between all the ribs (103) at the front end of the thermal conductive body (101) and flows backwards via an outer wall of the thermal conductive body (101). The LED head light is high in utilization rate of light, is good in heat dissipation effect, and is particularly suitable for a vehicle and a vessel.
