Title:
LENS CAPABLE OF FREELY ADJUSTING LIGHT CONCENTRATION ANGLE
Document Type and Number:
WIPO Patent Application WO/2023/045050
Kind Code:
A1
Abstract:
A lens capable of freely adjusting a light concentration angle, comprising: a cover (1), a lens (2) being connected to one side of the cover (1), and a convex thread (3) being provided on the surface of the lens (2); and an aluminum substrate (4) mounted on the side of the lens (2) away from the cover (1), a plastic cover (5) being connected to the side of the aluminum substrate (4) facing the lens (2), the side of the aluminum substrate (4) away from the plastic cover (5) being connected to the bottom of a lamp body (6), a heat dissipation device (7) being mounted on the outer wall of the bottom of the lamp body (6), and a recessed notch being provided at the bottom of the lamp body (6). According to the lens capable of freely adjusting a light concentration angle, when in use, the cover (1), the lens (2), the convex thread (3), the aluminum substrate (4), the plastic cover (5) and the heat dissipation device (7) are assembled on the lamp body (6); during use, angle adjustment is performed by rotating a wing of the lens (2), and the rotation angle of the lens (2) can be adjusted from left to right or from right to left; as the position of the convex thread (3) on the aluminum substrate (4) and the lens (2) changes, the focus point of a lamp would also change, so that the light exit angle of the lamp can be changed by means of the rotation of the lens (2) during use.
