LED (Light-Emitting Diode) shadowless lamp

Abstract

The invention relates to an LED (Light-Emitting Diode) shadowless lamp, which comprises a lamp body with a concave spherical surface, wherein a plurality of light source modules are distributed on the concave spherical surface of the lamp body; the center of the lamp body is provided with a handle; the light source module consists of a base, a plurality of luminous bodies and a surface cover; the edge of the surface cover and the edge of the base are provided with a plurality of buckling mechanisms for clamping the luminous bodies between the surface cover and the base respectively; an installation groove for accommodating a bracket shaft is formed at the central position of a radiating fin on the back face of the base of the light source module; a module bracket is embedded into the installation groove, and is movably hinged with the light source module through the bracket shaft; the bracket shaft is vertical to the radius position of the lamp body, so that light spots are positioned on the central axis of the lamp body during adjustment of the light emitting angle by using the light source module; and a control circuit comprises a singlechip and stepping motor which is electrically connected with the singlechip and is used for driving a respective corresponding light source module to change the irradiating direction.

Description

technical field [0001] The invention relates to an LED shadowless lamp. Background technique [0002] CN201010614515.2 discloses an "LED shadowless lamp", and its purpose is to provide an LED shadowless lamp with relatively uniform light in the irradiation area. The technical solution: The LED shadowless lamp includes a lamp body, a handle is provided in the center of the lamp body, and several LED sub-light sources are arranged around the handle, the lamp body has an inner spherical surface, and the LED sub-light sources are arranged on the inner spherical surface. The sub-light sources are all set towards the center of the inner spherical surface, and the distance between any two adjacent LED sub-light sources is equal; the LED sub-light sources form a group of regular hexagons centered on the handle, each regular hexagon The side length of the polygon gradually increases and the center coincides; the LED sub-light source includes a module base and a module housing. Its ...

Problems solved by technology

Its disadvantages are: Since the lamp body of the LED shadowless lamp looks like a concave spherical surface as a whole, the light source is distributed on the inner wall of the concave spherical surface, and the light source is also distributed spherically, so all the light will be concentrated on the center of the spherical surface

After the lamp body is made, the position of the center of the sphere is fixed, and the angle between the light source module and the center axis of the sphere cannot be adjusted according to the needs, so that the light spot position concentrated by the light source module moves up and down along the center axis of the sphere.
