Abstract

The invention discloses an LED (light-emitting diode) lamp with an adjustable light-emitting angle, which comprises a shell, at least one light-emitting diode and at least one Fresnel lens, wherein the light-emitting diode is accommodated into the shell; and the Fresnel lens is movably arranged at a light-emitting path of the light-emitting diode. The LED lamp disclosed by the invention has the advantages that through the structure, the Fresnel lens is adopted to replace traditional lens, therefore, the materials, volume and weight of the lens are greatly reduced; meanwhile, the distance between the Fresnel lens and the light-emitting diode can be adjusted freely according to the actual situations, therefore, the light-emitting angle of the light-emitting diode can be adjusted, and the effect of adjusting the illuminated area is further achieved.

Description

technical field [0001] The invention relates to an LED lamp with an adjustable luminous angle, in particular to an LED lamp which combines an LED luminaire and a Fresnel lens and can adjust the luminous angle at any time according to actual needs. Background technique [0002] Early light-emitting diodes (Light Emitting Doide; LED) are usually used as indicator lights, such as personal computer indicator lights, home appliance indicator lights, etc. In recent years, due to the advancement of technology, the manufacturing process and technology of light-emitting diodes Light-emitting diodes have the advantages of low power consumption, long service life, low voltage, etc., and have been widely used in lighting fields and even display applications, such as light-emitting diode street lights and light-emitting diode TVs. . [0003] Due to the principle of light-emitting diodes, light-emitting diodes are point light sources when they emit light. To use such point light sources ...
