Adjustable beam angle embedded LED lamp

Abstract

The invention discloses an adjustable beam angle embedded LED lamp. The adjustable beam angle embedded LED lamp comprises an outer ring, the top of the outer ring is connected with a radiator througha screw, and the top of the radiator is connected with a wire pressing sheet through a screw. The top of the radiator is connected with a light source fixing support through a screw. An LED is embedded in the position, corresponding to the light source fixing support, of the top of the radiator. The top of the light source fixing support is fixedly connected with a varifocus lens, the surface of the varifocus lens is sleeved with a front ring, and an inner ring is fixedly arranged on the top of the front ring. The change of the beam angle of the embedded lamp is achieved by integrally adjusting a displacement structure of the radiator, and the efficiency of the lamp can be improved by 20% or above in the large-angle state compared with an existing LED lamp. Through cooperation of the radiator, the light source fixing support, the LED and the varifocus lens, the problem that the light emitting efficiency losses of existing adjustable beam angle lamps are commonly too large, and consequently the light utilization efficiency is reduced is solved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an embedded LED lamp with an adjustable beam angle. Background technique [0002] Lamps with adjustable beam angle can generally only be realized on track or surface-mounted lamps. The embedded LED lamps designed by very few manufacturers can only keep the heat dissipation fixed. By adjusting the heat dissipation connection and fixing the lens The position of the inner or outer ring fitting with threaded structure is moved to adjust the beam intensity. The disadvantage is that the beam intensity of the lens with adjustable beam intensity is small when the light source is far away from the lens. angle (eg Figure 4 ). When the distance between the light source and the lens is relatively short, the beam power is a large angle (such as Figure 5 ). At small angles, the efficiency of lamps and lanterns is equivalent, but at large angles, the efficiency is very different. Due to the...
