Detailed Description

The utility model is further described in the following embodiments with reference to the figures, see fig. 1-3:

the utility model provides a mould alclad lamp body, includes moulded casing 1, and the upper end of casing 1 forms the appearance chamber 10 that has the upper shed, holds the chamber end of chamber 10 and offers the outlet 100 and the component groove 101 that are used for stretching out the power cord, hold and be provided with aluminum hull 2 in the chamber 10, aluminum hull 2's bottom with hold chamber end in chamber 10 offsets, aluminum hull 2's border upwards extend the shaping have with hold the aluminium annular wall 21 that chamber 10 lateral wall offsets, just aluminum hull 2's bottom offered with the breach 20 that outlet 100 and component groove 101 correspond, aluminum hull 2's inner shell end is fixed with PCB board 3, aluminum hull 2 and casing 1 are last all to have offered a plurality of corresponding mounting holes 30.

In the implementation process, the aluminum shell is pressed into the molded shell 1 in advance, the aluminum shell is firmly and firmly fixed in the molded shell in a tool extrusion mode, the PCB is installed, connecting wires on the PCB are penetrated out through the wire outlet 100, and meanwhile, a capacitor or battery part for the PCB can be embedded in the element groove 101.

Heat on the PCB board conducts heat through the bottom of aluminum hull to rationally carry out even outgoing with heat through the casing of moulding, prevent that local from being heated and damaging.

It should be noted that the plastic of the plastic housing is a heat conductive plastic.

Preferably, the upper edge of the aluminum annular wall 21 is formed with an outwardly extending blocking edge 22, and the inner side wall of the housing 1 is formed with a limiting convex ring 11 abutting against the lower end surface of the blocking edge 22.
