Title:
LED LIGHT ALUMINIUM SUBSTRATE STRUCTURE AND BRAND NEW REFLECTING ECONOMIC LED LIGHT USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/109319
Kind Code:
A1
Abstract:
Disclosed is an LED light aluminium substrate (4) structure, wherein the aluminium substrate (4) is circular in shape, a circular outer ring (41) is a complete circle, and the aluminium substrate (4) is fixed in an interference fit with a heat sink (7). Disclosed is a brand new reflecting economic LED light comprising a bulb (1), an LED chip (3), the aluminium substrate (4), a middle plate (5), a circuit board (6), the heat sink (7), a light body (8) and a light holder (9), wherein the LED chip (3) is mounted on an upper surface of the circular aluminium substrate (4), the middle plate (5) is mounted on an inner ring (42) of the circular aluminium substrate (4), an upper surface of the middle plate (5) forms a spherical face, the circuit board (6) is mounted below the aluminium substrate (4), the aluminium substrate (4) is fixed in an interference fit with the heat sink (7) via the outer ring (41) of the aluminium substrate, the circuit board (6) is located in the heat sink (7), the heat sink (7) is embedded in the light body (8), the light body (8) is mounted on the light holder (9), the bulb (1) is fixed on the light body (8), and the LED chip (3) is electrically connected to the light holder (9) via the circuit board (6). The LED light aluminium substrate has the features of optimal heat dissipation effects, high light flux and light-emitting efficiency, and low manufacturing costs. The structure is not limited in appearance, A-type, G-type, R-type and B-type all being possible, and the invention has a widespread range of application.
