Embodiment

[0021] The structure diagram of the present invention is as figure 1 As shown, the optical system for stage lamps of the present invention includes a light source 10, a light concentrating device 20, an effect assembly 30, a first optical assembly 40, and a second optical assembly 50 fixed to the light outlet of the lamp, which can be moved to block The position of the light beam and the first optical component 40 that moves to the position that does not block the light beam are movably installed between the effect component 30 and the second optical component 50 through a moving switching mechanism. into the main light beam 11 along the propagation direction of the light, when the first optical assembly 40 moves to the position of blocking the light beam, the main light beam 11 passes through the first optical assembly 40 after passing through the effect assembly 30 and then projects out through the second optical assembly 50, The first optical assembly 40 moves between the e...

Abstract

The invention discloses an optical system for stage lighting, comprising a light source, an optical collecting member, an effect component, a first optical component and a second optical component, wherein the first optical component capable of being moved to a position where a light beam is sheltered and a position where the light beam is not sheltered is assembled between the effect component and the second optical component through a movable switching mechanism; when the first optical component is moved to the position where the light beam is sheltered, a main light beam penetrates through the first optical component via the effect component, and then is projected via the second optical component; the first optical component is moved between the effect component and the second optical component along the primary optical axis of the main beam to realize different focal lengths; and when the first optical component is moved to a position where the light beam is almost not sheltered at all, the main beam is projected out through the second optical component via the effect component. When the optical system for stage lighting disclosed by the invention is used for stage lighting, through simple switching, the optical system can obtain two different lighting effects that could only be realized through two lamps in the past, so the optical system saves cost for users, as well as installation space that is limited on the stage.

Description

technical field [0001] The invention relates to an optical system for a stage lamp, which belongs to the transformation technology of the optical system for a stage lamp. Background technique [0002] Stage lighting has the following functions in modern stage performances: 1) performance lighting, so that the audience can see the actors' performance and the scene image clearly; 2) guide the audience's sight; The required space environment; 5) rendering the atmosphere in the play; 6) showing the transition of time and space, highlighting the contradictions and conflicts of the play and strengthening the rhythm of the stage, enriching the artistic appeal. The existing commonly used lights include: spotlight, beam light, soft light, follow spot light, astigmatism light, etc. Among them, the light of the soft light is soft and well-proportioned, which can not only highlight a certain part of the main body, but also have no hard spots, which is convenient for several lights. It ...
