Description

Zoom light fixture

This creation is about lamps, especially a zoomable light fixture.

A typical variable-focus lamp includes an inner sleeve and an outer sleeve that are relatively screwed by a screw, a light source is disposed in the inner sleeve, and the outer sleeve is provided with a lens corresponding to the light source. When the inner sleeve and the outer sleeve rotate relative to each other, the inner sleeve and the outer sleeve can be displaced by the screw to change the distance between the light source and the lens, thereby changing the projection path of the light source. However, the thread cannot be configured with a large inclination angle, and the stroke that can be moved every one rotation is limited, so it is necessary to configure a relatively long circumferential stroke, so that the friction distance of the screw is too long and it is easy to wear. Furthermore, there must be a gap between the male and female screws to rotate, thus making the actuation accuracy poor.

The present variable zoom luminaire is adapted for the user to rotate the outer flange 232 of the movable sleeve assembly 200, and the movable sleeve assembly 200 is positioned relative to the fixed sleeve assembly 100 by the sliding 520 engaging the helical arc groove 510. The central axis moves to change the ray casting path. Since the spiral arc groove 510 can be configured with a larger inclination angle than the screw, thereby reducing the stroke of the spiral arc groove 510, the wear rate between the sliding 520 and the spiral arc groove 510 can be reduced. The ball 522 abuts the spiral arc groove 510 to reduce the frictional resistance between the sliding 520 and the spiral arc groove 510 and eliminate the gap to increase the accuracy of the operation. Therefore, the zoom lens of the present invention can have better service life and accuracy. . Furthermore, the movable zoom unit 200 of the present invention can rotate and move at the same time, so that only a single component moves when the light projection path is adjusted, and the precision of the movement is high when the moving components are small. The recess 411 provided on the lens 400 allows the light unit 300 to be moved therein, thus enabling the movable sleeve assembly 200 to have a longer axial travel.
