Problems solved by technology

[0005] However, each of the air holes 912 used to suck air in this existing structure is also located above the lamp, so that the hot air discharged from each of the through holes 921 will also rise and be sucked again through each of the air holes 912. , affecting the cooling performance
And when the existing structure is embedded and hidden, although the penetration holes 921 are exposed on the ceiling surface, the ventilation holes 912 are still buried above the ceiling, so there are still poor air circulation and heat dissipation performances. Then generate heat accumulation and affect the service life of the lamp

Embodiment Construction

[0042] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:

[0043] Please refer to image 3 As shown, it is a lamp according to the first embodiment of the present invention. The lamp includes an outer cover 1 , a heat sink 2 , a fan 3 and a light emitting element 4 . Wherein, the heat sink 2 is arranged between the fan 3 and the light emitting element 4, and the outer cover 1 is arranged outside the heat sink 2, therefore, when the fan 3 is running, air can be sucked in and blown out through the heat sink 2 , so that the air in the outer cover 1 can circulate with the outside, so as to dissipate the heat energy generated by the light emitting element 4 .

[0044] One end of the cover 1 has an opening 11 , and a chamber 12 is recessed from the opening 11 .

Abstract

The invention relates to a light fitting and a heat radiator thereof. The light fitting comprises an outer cover, the heat radiator, a fan and a light emitting element; the outer cover is provided with an opening and an indent containing chamber; the heat radiator is arranged at the opening, and is provided with a side wall; the side wall is internally provided with a seat body; a clearance is reserved between the seat body and the inner circumferential wall of the side wall; the seat body is connected to the inner circumferential wall of the side wall by virtue of a plurality of first connecting pieces, thus a first air flow channel is formed between every adjacent first connecting pieces; a plurality of second connecting pieces are radially arranged between the outer circumferential wall of the side wall and the inner wall surface of the containing chamber; the fan is positioned in the containing chamber and is positioned at one side of the heat radiator; and the light emitting element is arranged at the other side of the heat radiator. Therefore, better air circulation and heat radiation efficacy can be provided.

Description

technical field [0001] The invention relates to a lamp and its radiator, in particular to a lamp and its radiator which uses a fan to drive air to circulate to assist heat dissipation, and is more suitable for embedded occasions to provide indoor or outdoor lighting. Background technique [0002] Existing lamp structures, such as the patent case of Taiwan Announcement M 330426 "Lamp Heat Dissipation Structure", please refer to figure 1 As shown, it is turned 180 degrees according to the actual installation direction of the lamp. The lamp has a heat dissipation base 81 , a circuit board 82 , a light emitting diode 83 , a heat dissipation fan 84 and a lamp holder 85 . The heat sink body 81 has a recessed portion 811 and an accommodating portion 812, the circuit board 82 and the LED 83 are arranged in the recessed portion 811, the cooling fan 84 is arranged in the accommodating portion 812, and the lamp cap 85 is combined on the outside of the accommodating portion 812 . Wher...
