A lighting adjustment device

Abstract

The invention discloses a light emission regulator comprising a light-emitting module and a zooming module. The light-emitting module comprises a body and a shade. The body is provided with a lighting end provided with a light-emitting unit. One end of the shade is rotatably fitted to the lighting end and encloses the light-emitting unit. The shade is provided with a zooming turn segment; the part, corresponding to the zooming turn segment, of the inner wall of the shade is provided with two opposing oblique guide grooves. The zooming unit comprises a reflector and a zooming member; the reflector is mounted at the lighting end of the body and disposed inside the shade; the reflector surrounds the light-emitting unit; the reflector is provided with two opposing limit elongated holes corresponding to the zooming turn segment. One end of the zooming member is provided with a focal part corresponding to the light-emitting unit. The light emission regulator has the advantage that zooming can be achieved just by mutual matching of the oblique guide grooves, the limit elongated holes and slide ribs.

Description

technical field [0001] The invention relates to a lamp, in particular to a light-emitting adjusting device which achieves the effect of quickly adjusting the zoom of the lamp with a simple structure. Background technique [0002] Lighting equipment has brought great reforms to the world of human civilization. Lamps replaced the weak light provided by candles in the past, and then provided moderate light in the surrounding environment, allowing humans to move around at night and in dark places. People's working environment is changing, and correspondingly, the demand for lighting equipment is increasing, such as flashlights, headlights, street lights, fluorescent lamps, desk lamps, etc. With the development of science and technology, the improvement of lighting equipment is constantly improving, and it is enough to simply provide lighting, which can no longer meet the needs of consumers. Therefore, in addition to providing photos, these lamps usually add additional functions...

Problems solved by technology

[0004] Although the above-mentioned zoom working light can achieve the effect of zooming by moving the second adjustment part relative to the first adjustment part; image 3 and Figure 4 It can be clearly seen from the cross-sectional view that the first adjustment part and the second adjustment part are the cooperation of male and female threads, and the effect of zooming is achieved by the screw movement of the second adjustment part relative to the first adjustment part; if the first adjustment part If the male thread of the first adjustment part and the female thread of the second adjustment part are to provide smooth movement, the fineness of processing must be very particular. The design of the mold cannot be sloppy. The tolerance of the designed male and female threads should be small, so in the processing process It is time-consuming and labor-intensive, and the processing cost will increase accordingly
