Detailed Description

The invention is further illustrated by the following figures and examples.

In a first embodiment, as shown in fig. 1 to 4, a down lamp includes a lamp housing 1, an aluminum cup 2, a driving power source 3, a light source 4, and a light-transmitting cover 5. The lamp housing 1 is a horn-shaped structure made of high-thermal-conductivity plastic, an opening of the lamp housing 1 is arranged downwards, spring buckles 10 are arranged on two sides of the lamp housing 1, a plurality of grooves 11 are formed in the top surface of the lamp housing 1, and heat dissipation protrusions 12 are formed between the grooves 11. The lamp housing 1 comprises an upper chamber 13 and a lower chamber 14, the upper chamber 13 is communicated with the lower chamber 14, a plurality of convex edges 15 are arranged at the separation positions of the upper chamber 13 and the lower chamber 14, and the convex edges 15 are arranged in a circular shape at equal intervals.

The aluminum cup 2 is arranged in the upper cavity 13 downwards through an opening, the bottom surface of the aluminum cup 2 is abutted to the top surface of the convex edge 15, the side wall of the aluminum cup 2 is tightly attached to the side wall of the upper cavity 13, a containing cavity 16 is formed between the top surface of the aluminum cup 2 and the lamp housing 1, the driving power supply 3 is arranged in the containing cavity 16, the light-transmitting cover 5 is arranged in the lower cavity 14, and the light-transmitting cover 5 is connected with the lamp housing 1 in a buckling mode. Preferably, the bottom surface of the light-transmitting cover 5 is flush with the bottom surface of the lamp housing 1.

2 top surfaces of aluminium cup are equipped with first through-hole 21 and second through-hole 22, and first through-hole 21

intercommunication holding chamber

16 and 2 inner chambers of aluminium cup, and holding chamber 16 of lamp body 1 corresponds second through-hole 22 and extends there is reference column 17, light source 4 is lamp plate 41 of taking lamp pearl 40, and lamp plate 41 uses lamp pearl 40 to arrange aluminium cup 2 in down, and lamp plate 41 passes through bolted connection with reference column 17.

In this embodiment, the groove 11, the heat dissipating protrusion 12, the protruding edge 15 and the lamp housing 1 are integrally formed by injection molding. When the lamp housing 1 is subjected to injection molding, the aluminum cup 2 is placed in the upper cavity 13 of the lamp housing 1, after the lamp housing 1 is cooled, the side wall of the upper cavity 13 is tightly attached to the side wall of the aluminum cup 2, the bottom surface of the aluminum cup 2 is placed above the convex edge 15, and the aluminum cup 2 is blocked by the convex edge 15 and cannot be separated from the upper cavity 13. Because aluminium cup 2 and lamp body 1 all have good heat conductivity, the heat that gives off when light source 4 is luminous gives off the external world from lamp body 1 through aluminium cup 2, and drive power supply 3's heat is given off to the external world through lamp body 1 top recess 11 and heat dissipation arch 12.
