Description

Technical Field

[0001] This utility model relates to a lamp, and more particularly to an LED lamp with an adjustable light emission angle. Background Technology

[0002] The beam angle is an important parameter describing the range of light distribution from a light source or light-emitting device (such as LEDs, lamps, etc.). It usually refers to the angle between two directions where the light intensity is 50% (or a specific percentage) of the central luminous intensity. Traditional lighting products require adjusting the lens's mounting position and height, or directly replacing the lens, to adjust the beam angle. For traditional beam angle adjustment methods, regardless of whether the adjustment is done by adjusting the lens's mounting position and height or by directly replacing the lens, operators need to install and remove multiple fixing screws to complete the operation. This process is cumbersome, inefficient, and carries the risk of seal failure after the operation. Utility Model Content

The DIP switch assembly is electrically connected to the driver power supply. The middle cover is vertically opposite to the DIP switches and can be freely attached and detached from the lens. The bottom surface of the lens is concave in the middle to form a receiving groove. The DIP switches extend into the receiving groove, and the middle cover extends into the receiving groove and blocks the opening of the receiving groove.

[0005] In one embodiment, the lens is further provided with several protruding ribs on the wall of the receiving groove. The middle cover includes a base plate, an inner ring and an outer ring connected to the base plate. The inner ring and the outer ring are arranged in a ring shape. The axis of the inner ring is perpendicular to the base plate, and the axis of the outer ring is perpendicular to the base plate. The outer ring surrounds the outer side of the inner ring. The outer peripheral surface of the outer ring is provided with several positioning grooves. During assembly, the protruding ribs are engaged in the positioning grooves.

[0006] In one embodiment, the ribs are evenly spaced in the circumferential direction, and the positioning grooves are evenly spaced around the axis of the outer ring.
