Title:
LED ELEVATOR LAMP HAVING HEAT DISSIPATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2019/144328
Kind Code:
A1
Abstract:
An LED elevator lamp having a heat dissipation function, fan blades (6) being provided at both left and right sides of the bottom of an outer bearing ring (5), a heat absorption plate (7) being provided at the center of the bottom of an elevator top plate (1), a heat conductive rod (702) being provided on one end of the heat absorption plate (7) and having left and right sides each provided with a heat conductive block (704), heat dissipation fins (705) being uniformly provided on the surface of the heat conductive block (704), an LED lamp (9) being provided on both left and right sides of the heat absorption plate (7) by means of a connecting rod (8), both left and right sides of a refractive layer (11) and both left and right sides of a protective cover (10) being provided with matching through holes (13), fans (3, 5, 6) being provided on the top of the elevator, the fans (3, 5, 6) being in a communication state with the LED lamp (9), the wind power generated during the upward and downward movement of the elevator serving as the rotating force of the fans (3, 5, 6) to drive the fans (3, 5, 6) to rotate, and the heat generated by the LED lamp (9) being absorbed, dissipated and then blown away during rotation of the fans (3, 5, 6). The LED lamp (9) is provided with the heat absorption plate (7) and a heat dissipation plate (701), such that the LED lamp (9) has an improved heat dissipation function, preventing the LED lamp (9) from being burned as a result of excessively high temperature, thus improving the service life of the LED lamp (9).
