Embodiment Construction
[0026] As shown in FIG. 1 , the LED lighting lamp of the present invention includes a housing 1 , a circuit board 2 , a plurality of LED light sources 3 , a transparent cover 4 , an AC / DC constant current drive power supply 5 , and a plurality of reflector cups 6 .
[0027] Wherein, the shell 1 is formed by one-time die-casting of aluminum alloy, and the back shell 11 of the shell 1 has a heat sink 12 . The shell 1 is made of aluminum alloy, because aluminum alloy is an excellent heat conductor, which can quickly conduct heat generated in the shell 1, and a heat sink 12 is set on the back shell plate 11 of the shell 1, which not only increases the heat dissipation of the back of the shell. The heat dissipation surface area also causes a temperature difference between the inner and outer distances, so that the heat in the shell 1 can be dissipated more quickly.
[0028] The circuit substrate 2 adopts an aluminum substrate 21 , and the aluminum substrate 21 is directly attached ...
