An energy saving lighting device

Abstract

The application relates to the technical field of lighting devices, and discloses an energy-saving lighting device, which comprises a shell, a light source module arranged in the shell, the light source module being used for providing a lighting light source, the light source module bottom being connected with the inner wall of the shell through a flexible reflection film, the outer wall of a heat dissipation part of the upper part of the light source module being provided with a heat dissipation module, the heat dissipation module being used for absorbing heat emitted by the heat dissipation part of the light source module, a displacement module being further arranged above the light source module, a fluid control module being further arranged in the shell, the fluid control module being used for driving fluid to circulate in the heat dissipation module and controlling the volume of the fluid injected into the displacement module, and the displacement module driving the light source module to ascend and descend. Through cooperation of the fluid control module, the displacement module and the heat dissipation module, the control of the flexible reflection film and the heat dissipation system of the device are integrated, the flexible reflection film curvature change is adjusted by fluid pressure, and the light source module is rapidly cooled.
