Description
Technical Field
[0001] The invention relates to the field of lamps, and in particular to a heat dissipation structure of a lamp board with an aluminum substrate and a downlight using the heat dissipation structure. Background Art
[0002] A downlight is a lighting fixture embedded in the ceiling. As a concealed fixture embedded in the ceiling, all the light from the downlight is projected downward. When emitting light, different reflectors, lenses, blinds, and bulbs can be set on the reflective cup of the downlight to change the lighting effect of the downlight, thereby achieving different illumination effects.
[0003] At present, the lamp board of downlight is usually made of aluminum substrate, which is a metal-based copper-clad plate with good heat dissipation function. Generally, a single-sided board consists of three layers, namely the circuit layer (copper foil), the insulation layer and the metal base layer. It is commonly used in LED lighting products. There are two sides, the white side is for welding LED pins, and the other side is the original color of aluminum. Generally, thermal conductive slurry is applied to contact the thermal conductive part.
[0004] After the existing downlight is installed, the heat emitted by the light board will pass through the heat dissipating silicone grease and the highly reflective aluminum radiator in turn and then dissipate into the air, thereby reducing the risk of overheating of the light board; however, in this process, the heat dissipation channel of the downlight is too long and the heat dissipation effect is poor. Summary of the invention

[0008] By adopting the above technical solution, the lamp panel is directly in contact with the outside air, so that the heat generated when the lamp panel is heated is directly introduced into the air; compared with the prior art in which the heat is dissipated into the air after passing through the lamp panel, silicone grease and highly reflective aluminum radiator in sequence, this design can directly transmit the heat to the air, shorten the heat dissipation distance, and at the same time reduce the use of the radiator, thereby reducing the weight and components of the downlight using the heat dissipation structure and reducing the overall cost of the downlight.

[0015] In the second aspect, the present application provides a downlight using the heat dissipation structure, which adopts the following technical solution:
[0016] The downlight using the heat dissipation structure includes the reflector cup and the light board, wherein the reflector cup is hollow and the light board is installed at one end of the reflector cup, and the cross-sectional area of the light board gradually increases from the end close to the light board to the end far from the light board.
[0017] By adopting the above technical solution, the light is gathered by using reflective cups with gradually increasing diameters, thereby improving the lighting effect of the downlight.
[0018] Preferably, a clamping ring is sleeved on one end of the reflective cup away from the lamp board, and a fastener for fixing the downlight at a predetermined installation position is provided on the clamping ring.

This connection structure utilizes the telescopic and deformable coil part of the torsion spring. Workers only need to press the coil part to install the torsion spring, thereby realizing the rapid disassembly and assembly of the torsion spring on the downlight.
