Abstract

The utility model relates to a large-power LED (light emitting diode) piercing lamp, which is formed by a lens assembly, a glue solidifying body, a PCBA (printed circuit board assembly), a radiating fin assembly, a shrapnel and a rear cover; the PCBA is formed by a PCB (printed circuit board), a paster LED and a lead; the electrode of the paster LED is connected to the lead by the PCB; the lead penetrates through the radiating fin assembly and the shrapnel and is lead out from the rear cover; the radiating gin assembly is formed by a radiating fin and four limiting bolts; the radiating fin is fixed on one side, away from the paster LED, of the PCB by the limiting bolts; the lens assembly is formed by a lens shell and two fixing bolts; the lens shell is provided with a hollow cavity defined by an edge wall and a lens bottom surface; the PCBA and the radiating fin assembly are placed in the hollow cavity; glue is filled in the hollow cavity and is cured to form the glue solidifying body; the PCBA, the radiating fin assembly and the hollow cavity in the lens shell are connected together by the glue solidifying body; the shrapnel is arranged at one side, away from the PCB, of the radiating fin and is connected onto the lens shell by the fixing bolts; the rear cover is buckled on the shrapnel. The large-power LED piercing lamp has the beneficial effects that the radiating power of the large piercing lamp is improved by the radiating fins arranged under the PCB, the thermal work stability of the large-power piercing lamp is ensured and the service life of the large-power piercing lamp is favorably prolonged; the shrapnel and the lens shell are tightly connected by the fixing bolt, so the integral structure of the large-power piercing lamp is more compact and the mounting of the large-power piercing lamp is facilitated.

Description

Great power LED perforated lamp

Technical field

The utility model relates to LED lighting technical field, relates in particular to a kind of great power LED perforated lamp.

Background technology

Great power LED has the advantages such as volume is little, power consumption is little, it is little to generate heat, life-span length, fast response time, safety low-voltage, good weatherability, good directionality as lighting source.And great power LED, as possessing the title of " green illumination light source ", is expected to replace incandescent lamp, halogen tungsten lamp and fluorescent lamp become 21 century a new generation's light source.

With respect to standard LED, the required circuit of great power LED is more complicated, needs larger structure space, and can produce more heat during work, makes junction temperature too high, has a strong impact on service life and the efficiency of great power LED.The method that solves at present great power LED perforated lamp heat dissipation problem is mainly to improve its radiating effect by the installation of fin, but because fin need to occupy certain space, great power LED perforated lamp volume increases, run counter to the light small and exquisite requirement of product, also improve processing cost simultaneously, be unfavorable for large-scale production.

Summary of the invention

In order to solve the problem of above-mentioned existence, the utility model provides a kind of great power LED perforated lamp overall structure.

The utility model solves the technical scheme that its technical problem adopts:

A kind of great power LED perforated lamp, by lens subassembly, the glue solidifies body, PCBA assembly, heat sink assembly, shell fragment, bonnet composition, PCBA assembly is by pcb board, paster LED and wire composition, the electrode of paster LED connects wire by pcb board, wire is through heat sink assembly and shell fragment, from bonnet, draw, heat sink assembly is comprised of fin and four limited screws, fin is fixed on the side of pcb board away from paster LED by limited screw, lens subassembly is comprised of lens case and two fixed screws, lens case has a cavity being surrounded by limit wall and lens bottom surface, this cavity is placed PCBA assembly and heat sink assembly, glue pours into this cavity, the body that forms that the glue solidifies after the glue solidifies, the glue solidifies body is by PCBA assembly, heat sink assembly and lens case internal cavity link together, shell fragment is placed in fin away from pcb board one side and is connected on lens case by fixed screw, bonnet is fastened on shell fragment.

A kind of great power LED perforated lamp of the present utility model, the beneficial effect of its generation is: the radiating efficiency that is placed in fin under pcb board and has improved high-power perforated lamp, guaranteed the heat endurance of high-power perforated lamp work, be conducive to high-power perforated lamp life-time dilatation, and shell fragment closely links together by fixed screw and lens case, make the overall structure of high-power perforated lamp more compact, be conducive to the installation of high-power perforated lamp.
