Problems solved by technology

The light emitting angle of the light-emitting diode is generally 90 degrees to 120 degrees, and the light intensity in the center (the light emitting angle is about 0 degrees to 30 degrees) is relatively strong, while the surrounding light intensity is relatively weak, resulting in uneven light emitting from the entire light source module and irradiating The range is small, and the irradiation range is fixed and cannot be adjusted flexibly, so that the application of the light source module with this LED is limited to a certain extent

Abstract

A lighting device comprises a light-emitting module, a lampshade and a supporting body, wherein, the light-emitting module is provided with a light-emitting surface; the lampshade is provided with a reflecting surface which is arranged opposite to the light-emitting surface of the light-emitting module and is used for receiving the light sent out by the light-emitting surface and reflecting the light; the light-emitting module and the lampshade are respectively arranged on the supporting body; the lampshade is pivoted with the supporting body to enable the lampshade to be rotated a predetermined angle relative to the light-emitting module.

Description

technical field [0001] The invention relates to a lighting device, in particular to a light emitting diode lighting device. Background technique [0002] Currently, light emitting diodes (Light Emitting Diode, LED) have been widely used in many fields due to their characteristics of low power consumption, long life, small size and high brightness. Here, a new type of light-emitting diode can be found in the article "Illumination With Solid State Lighting Technology" by Daniel A. Steigerwald et al. in IEEE Journal on Selected Topics in Quantum Electronics, Vol.8, No.2, March / April 2002. [0003] Light emitting diodes can be applied to light source modules, such as street lamps. The light emitting angle of the light-emitting diode is generally 90 degrees to 120 degrees, and the light intensity in the center (the light emitting angle is about 0 degrees to 30 degrees) is relatively strong, while the surrounding light intensity is relatively weak, resulting in uneven light emitt...
