Title:
LED LAMP
Document Type and Number:
WIPO Patent Application WO/2017/140155
Kind Code:
A1
Abstract:
Disclosed is an LED lamp, comprising a power source (20) used for converting an external power source into a power supply voltage for a lamp, a power supply bottom plate (10) and a power supply cover plate (30), at least two blocks of LED light source plates (50) and two heat-dissipating devices (60), wherein the two heat-dissipating devices (60) are respectively provided at both sides of the power source (20); the two blocks of LED light source plates (50) are respectively fixed on a light source mounting face (65) below the two heat-dissipating devices (60); and the two blocks of LED light source plates (50) increase the light source area and reduce glare; and each elongated heat-dissipating device (60) with a hollow structure and a substantially triangular cross section is provided with a bottom close to the power source (20), and the inner and outer parts are respectively provided with vertical inner and outer grooves (61, 62). Two symmetrical side covers (70) provided at both ends of the heat-dissipating device (60) are provided with ventilating holes (75). One side of each ventilating hole (75) is provided with a protrusion (72), and the protrusion and a fixed groove (64) provided on the light source mounting face (65) are fitted to each other so that an inner space of the heat-dissipating device (60) with a hollow structure communicates with the outside via the ventilating holes (75) on the side covers (70) at both ends. The enclosed structure not only increases the heat-dissipating area, but also enables only one side of the enclosed structure to face outwards, and in addition, the inner groove (62) is located in the elongated heat-dissipating device (60), so dust is not easily deposited.
