Mixed variable focal length module and lamp adopting same

Abstract

The invention discloses a mixed variable focal length module. A fixed focal length assembly and a variable focal length assembly are included. The variable focal length assembly comprises a variable focal length light source part, a guiding ring, a rotating ring and a connection part; the variable focal length light source part is installed in the guiding ring, and the rotating ring is arranged inthe guiding ring in a sleeved manner; a lens part is arranged on the rotating ring; the lens part and the variable focal length light source part are sequentially arranged from top to bottom; the rotating ring is rotationally connected with the guiding ring through the connection part; the rotating ring rotates so that the lens part can be close to or away from the variable focal length light source part; the fixed local length assembly comprises a base plate, a plurality of high color temperature light source parts and a plurality of low color temperature light source parts; the base plate is arranged on the rotating ring; the middle portion of the base plate is provided with a light transmitting channel arranged in a through manner; the light transmission channel, the lens part and thevariable focal length light source part are coaxially arranged in sequence from top to bottom; and the high color temperature light source parts and the low color temperature light source parts are arranged in a spaced manner, and are annularly distributed around the axis of the light transmission channel. The mixed variable focal length module is good in heat dissipating performance and light outgoing effect.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a hybrid zoom module and a lamp using the module. Background technique [0002] In the existing lighting field, the general zoom module, that is, the zoom LED lamp, usually adjusts the focal length by mechanically adjusting the height of the light source component, and the power required for the zoom LED lamp is relatively large, because the light source is generally set at The interior of the lamp leads to poor heat dissipation performance. If the power of the zoom LED light is reduced, the brightness of the zoom LED light will not be enough. At the same time, the general zoom module also has the problem of narrow lighting range and poor lighting effect. In addition, adjusting the height of the light source assembly to change the focal length is usually done by rotating it. There is a rotation gap inside it, and it is easy to make abnormal noise when shaking or rotati...
