Problems solved by technology

[0005] Using the above methods, although the adjustment of the light spot has been realized, when a multi-group lens combination structure is used, multiple lenses need to be arranged in the optical system, so that the entire optical system has a large number of components and a complex structure, which is inconvenient for manufacturing and post-processing. Maintenance; when using shading parts, the shading parts will block part of the light, so that the light emitted by the light source cannot fully participate in the lighting work, the luminous flux is lost, and the light utilization rate is not high.

Embodiment 1

[0040] Example 1: Such as Figure 1-4 As shown,

[0041] A zoom lens includes a lens body 1. The lens body 1 includes an incident surface for refracting light from a light source 7 into the lens body 1, an exit surface for refracting light from the lens body 1 out of the lens body 1, and The part of the incident light entering the light is reflected to the reflecting surface 4 of the exit surface. The entrance surface corresponds to at least one light source movement interval 8. When the light source 7 moves within this interval, the light beam is refracted by the exit surface. The beam angle becomes larger or smaller accordingly.

[0042] Since the zoom lens of this embodiment has a light source movement interval 8, when the light source 7 moves within this interval, the beam angle of the light beam refracted by the exit surface becomes larger or smaller correspondingly, that is, in the actual optical system In this, only need to move the light source 7 within the light source m...

Embodiment 2

[0057] Example 2, such as Figure 1-4 As shown,

[0058] A zoom optical system includes the zoom lens of Embodiment 1 and a light source 7, and the light source 7 is slidably arranged on the light source movement interval 8 of the zoom lens.

[0059] The zoom optical system of this embodiment adopts the above-mentioned zoom lens, which further simplifies the internal structure of the zoom optical system, and also ensures the lossless luminous flux.

Embodiment 3

[0061] A zoom lamp includes the zoom lens of Embodiment 1 or the zoom optical system of Embodiment 2.

[0062] The zoom lamp of this embodiment adopts the above-mentioned zoom lens or zoom optical system, which further simplifies the internal structure of the zoom lamp and also ensures the lossless luminous flux.

Abstract

The invention relates to the technical field of optical lighting, in particular to a zoom lens, zoom optical system and zoom lamp. The zoom lens comprises a lens body. The lens body comprises an incident plane allowing light of a light source to be refracted to enter the lens body, an emergent plane allowing the light in the lens body to be refracted out of the lens body, and a reflection plane used for reflecting part of the light entering from the incident plane to the emergent plane. The incident plane is correspondingly provided with at least one light source moving interval. When the light source moves in the at least one interval, the light beam angle of a light beam refracted out of the emergent plane can be correspondingly increased or decreased. By the adoption of the zoom lens, compared with a traditional zoom optical system and a zoom lamp, there is no need to set a plurality of groups of optical lenses for zooming at first, and thus the internal structure of the optical system is greatly simplified; and meanwhile, there is no need to set a shading assembly to stop light, and hence luminous flux losses are reduced.

Description

Technical field [0001] The invention relates to the technical field of optical lighting, in particular to a zoom lens, a zoom optical system and a zoom lamp. Background technique [0002] In the field of lighting technology, in order to distribute the light emitted by the light source according to the needs of people, it is usually necessary to use various light conversion devices to reflect, refract, gather, or diverge the light, thus changing the propagation path of the light , And finally get the lighting area that meets the actual needs of people. [0003] In the current light conversion device, the lens is widely used, because each side of the lens can be used as a reflecting surface for reflecting light or as a refracting surface for refracting light. The relative position of each side is uniform, which has good reliability and Consistency, convenient processing and simple manufacturing. [0004] However, in the actual design work, the inventor found that the current lens sti...
