Embodiment Construction

[0025] Figure 3a It is a perspective view of the spotlight 4 (without heat dissipation structure installed). The spotlight comprises a lamp body 3, a mounting ring 1 for installing the spotlight, and a moving ring 2 for axial rotation on the side. And the common axis 5 (shown by dotted line) of the above three. The spotlight is installed on the ceiling (or called the suspended ceiling) through the assembly opening and the heat dissipation structure is arranged in the space between the ceiling and the suspended ceiling, such as Figure 3b shown.

[0026] Figure 4a is the first state of the heat dissipation structure 100 according to the present invention. The heat dissipation structure according to the present invention is designed to be adjustable. In the first state, the heat dissipation fins 6 installed in the heat dissipation structure behind the lamp body 3 are in a folded state, wherein each heat dissipation fin 6 surrounds the heat conduction base 7 closely with e...

Abstract

The invention relates to a radiating structure (100) for a spotlight. The radiating structure comprises a heat-conducting matrix (7) and a plurality of radiating fins (6) distributed in a circumferential direction of the heat-conducting matrix (7), and is characterized by being provided with a first state and a second state, wherein in the first state, the plurality of radiating fins (6) are folded and are close to the heat-conducting matrix (7), and in the second state, the plurality of radiating fins (6) are unfolded from the heat-conducting matrix (7). According to the radiating fins of the radiating structure, because the radiating fins can be converted between different folding states and unfolding states, higher radiating capacity can be realized when the spotlight works under the condition that installation of the spotlight is not influenced.

Description

technical field [0001] The invention relates to a heat dissipation structure for spotlights. Furthermore, the invention relates to a downlight comprising such a cooling structure. Background technique [0002] In the field of LED light source, the heat generated by the LED light source in the working process has a great influence on the service life of the LED light source. Therefore, the problem of heat dissipation has always been a concern in this field. This LED light source usually appears in the form of a spotlight (or called a dome light). It is installed in the ceiling through a corresponding assembly opening provided on the ceiling (or called a suspended ceiling). At this time, the maximum size of the LED spotlight needs to be designed to ensure that it can pass through the assembly opening. Since the shape and size of the assembly opening needs to match the shape and size of the LED spotlight itself, the size of the heat dissipation structure arranged at the rear...
