High-heat-dissipation lampshade of solar street lamp

Abstract

The invention belongs to the field of illumination, and particularly relates to a high-heat-dissipation lampshade of a solar street lamp. The high-heat-dissipation lampshade of a solar street lamp comprises: a lamp shell, wherein a cavity is formed in one side of the lamp shell; a lampshade which covers the cavity and is detachably mounted on the lamp shell; an aluminum substrate which is located in the cavity, wherein a lamp holder is arranged on the side, opposite to the lampshade, of the aluminum substrate, a control circuit board is fixedly connected to the side, away from the lamp holder, of the aluminum substrate, a controller is arranged on the control circuit board, and the controller is electrically connected with the lamp holder through a circuit printed on the aluminum substrate; and a heat dissipation assembly which is located between the aluminum substrate and the lampshade and comprises a support fixed to the inner wall of the cavity, wherein a thermal expansion block is fixed to the support and connected with a heat dissipation plate, heat dissipation fins are evenly distributed on the heat dissipation plate, and a channel allowing the heat dissipation fins to penetrate through is formed in a lamp shell main body.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a high heat dissipation solar street lamp shade. Background technique [0002] Due to its good energy saving and stability, LEDs have been well promoted; at the same time, the problems encountered by LEDs are also very obvious, mainly due to heat generation; LED chips, as the basic components of LEDs, due to their internal PN junction Temperature is very sensitive. Therefore, as the LED temperature rises, the luminous efficiency of the LED chip will decrease significantly; if the heat dissipation problem of the LED is not properly dealt with, its efficiency will be very limited. Contents of the invention [0003] The purpose of the present invention is to provide a high heat dissipation solar street lamp shade with reasonable structure and adjustable heat dissipation. [0004] In order to achieve the above-mentioned purpose of the invention, a kind of high heat dissipation so...
