Problems solved by technology

It can be seen that two aluminum substrates are involved in this patent, but its supplementary light rendering effect is only as described in the article "low-power LED lamp beads are emitted through the flat mirror surface 32 of the complete optical lens combination mirror 3 to complete the rendering embellishment effect .”, the light emitted by this device will have a lot of stray light, and in terms of color mixing effect, it does not involve other improvements, that is, its patent only adds a low-power aluminum substrate to the traditional zoom structure, and for The details of the added low-power LED are not described too much

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] In this embodiment, as attached figure 1 and 2 As shown, the LED zoom structure with a backlight cover and a diffusion film, from top to bottom, is a combined lens plate (1), a diffusion film (2), a backlight cover (3), a screw focus motor (4), Light guide (5) column, LED lamp bead P2 (62), aluminum substrate two (7), LED lamp bead P1 (61), aluminum substrate one (8), radiator (9).

[0023] There are multiple convex lenses (11) on the combined lens plate (1) for spot magnification; the diffusion film (2) is circular and attached to the backlight cover (3), and there are 3 focusing motor holes on the surface; the backlight cover (3) It is in the shape of a circular cover, with multiple light holes (32) on the surface, and three focusing motor holes (33). There are multiple buckle angles (31) on the lower edge of the backlight cover (3), Buckle ...

Abstract

In the actual use of a lamp, through three screw motors, a combination lens plate is controlled to move up and down to achieve the effect of light zoom, and in addition, due to the design of two aluminum base plates, the lamp has both the focus function and rendering effect; at the same time, a lens hood and diffusion film which are optimally designed are used for filtering stray light to the greatest extent and eliminate dark areas between a plurality of lenses on the combination lens plate at the same time, compared with conventional zoom lamps, the light spot of an LED zoom structure with abacklight hood and a diffusion film obviously blends better, a light emitting surface is larger, and the uniformity of the light spot is higher.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to the field of stage lighting. Background technique [0002] With the development of social entertainment, the application of stage lamps is becoming more and more extensive. Most of the existing zoom stage lamps use the combination mode of focusing screw motor + lens. This structure can make the light spot of the lamp have the function of focusing. , but does not have other stage lighting effects. How to have other lighting effects while having the focusing function, and at the same time increase the uniformity of the light spot is a new topic. [0003] For example, the utility model patent with the publication number CN204227347U is a zoom device for lamps. It is mentioned in claim 1 that "the zoom power mechanism includes a motor, a screw nut transmission mechanism, a guide rod, and a guide rod fixing plate"; its specification In the specific embodiment, it is mentioned that ...
