Focusing assembly for track lamp and track lamp using focusing assembly

Abstract

The invention relates to a focusing assembly for a track lamp and the track lamp using the focusing assembly. The focusing assembly for the track lamp comprises a lamp barrel, a light source, a concave-convex lens and a zoom lens which are coaxially arranged, the concave-convex lens is fixedly arranged in the lamp barrel, the light source is fixedly arranged on the concave side of the concave-convex lens, the focusing assembly further comprises a rotating sleeve and a translation sleeve, the translation sleeve is in threaded fit with the rotating sleeve, a limiting insertion strip of the translation sleeve is arranged in an insertion strip slide way, so that when the rotating sleeve is rotated, the rotating sleeve can be driven to rotate in the lamp barrel, and the translation sleeve is driven by the rotating sleeve to axially translate along the lamp barrel, so that the axial distance between the zoom lens and the concave-convex lens is adjusted.

Description

Technical field [0001] The invention relates to the technical field of lighting auxiliary equipment, in particular to a focusing assembly for track lights and a track light using the focusing assembly. Background technique [0002] A track light is a light installed on a similar track, which can adjust the angle of illumination at will. It is generally used as a spotlight in places that require key lighting. It is also called track spotlights, track lights, etc., mainly using COB light sources, with light effects The characteristics of high, uniform light, no glare, energy saving and environmental protection, are the preferred equipment in the lighting equipment; the existing track light, in the patent document with the authorized announcement number CN208011429U and the name of a focusing track light, records a This is composed of a fixed ring fixed at the end of the lamp body, a focusing ring fixed at the outer end of the fixed ring and rotatable relative to the fixed ring, arr...

Problems solved by technology

[0002] Track light is a light installed on a similar track, and the irradiation angle can be adjusted arbitrarily. It is generally used as a spotlight in places that require key lighting. It is also called track spotlights, track lights, etc. It mainly uses COB light sources and has light effects. High, uniform light output, no glare, energy saving and environmental protection, it is the preferred equipment in lighting equipment; the existing track light, in the patent document with the authorized announcement number CN208011429U and the name of a focus-adjustable track light, records a A fixed ring fixed on the outer end of the lamp, a focus ring fixed on the outer end of the fixed ring and rotatable relative to the fixed ring, and surrounded by the focus ring and the fixed ring The focus assembly composed of the rotating face ring in the space and the focusing lens arranged in the rotating face ring, when the focus ring is rotated, the first internal thread and the first external thread act on the rotating face ring along the axial direction Move back and forth, thereby driving the focusing lens to move forward and backward along the axial direction, thereby changing the distance between the focusing lens and the light source, adjusting the light angle of the light source, and playing the role of focusing. After the focusing assembly of the above structure rotates, it extends out of the front end of the lamp body ,Affect the appearance
