Embodiment 1

[0048] In this embodiment, each illuminant group 11 includes two different illuminants, and the position adjustment mechanism 30 is connected to the collimator lens mechanism 20 as an example. In other embodiments, more than two different illuminants may be included, and the position The adjustment mechanism 30 can be connected with the light source mechanism 10 , or the position adjustment mechanism 30 can be connected with the pinching lens mechanism 60 . When the light source adjusting device 100 of this embodiment is in the initial position, the collimating lens mechanism 20 is in the first position, and the lens unit of the collimating lens mechanism 20 is aimed at the first type of illuminant and collimates the light beam emitted by it. When the spot effect needs to be changed, the driving member 33 drives the first fixed assembly to move along the axial direction of the first shaft assembly 32, so that the collimating lens mechanism 20 is located at the second position, ...

Embodiment 2

[0074] The structure and principle of this embodiment are similar to that of Embodiment 1, the difference is that at least one group of said illuminants 11 in this embodiment includes at least three different illuminants, and said position adjustment mechanism 30 also includes a first fixed The sliding stroke of the seat assembly 31 or the second fixed seat assembly 41 is limited by the third limiting unit 50, so that the collimating lens mechanism 20 is limited to the third position or the mth position by the third limiting unit 50, so that the lens unit Aim at the third illuminant or the mth illuminant.

[0075] Such as figure 1 , figure 2 combine Figure 9 As shown, this embodiment takes limiting the sliding stroke of the second fixing seat assembly 41 as an example, and it can also be set to limit the first fixing seat assembly 31 in other embodiments. The third limiting unit 50 is a solenoid valve push rod. When the solenoid valve is energized, it can control the tele...

Embodiment 3

[0077] Such as Figure 10-11 As shown, the structure and principle of this embodiment are similar to those of Embodiment 1 and Embodiment 2. The difference is that the light source adjustment device 100 of this embodiment includes a retractable lens mechanism 60 , and the position adjustment mechanism 30 is connected to the retractable lens mechanism 60 . By setting the position adjustment mechanism 30 to connect with the retracting lens mechanism 60, the relative displacement between the retracting lens mechanism 60 and the light source mechanism 10 is controlled, so that the lens units on the retracting lens mechanism 60 can be aligned with different illuminants for retracting, thereby realizing different Spot effect.

[0078] In addition, the light source adjustment device 100 of this embodiment also includes an optical assembly 70, which is used to collimate and / or homogenize the light collected by the converging lens mechanism 60, and then output the light through the foc...

Abstract

The invention relates to a light source adjusting device. The device comprises: a light source mechanism which is provided with at least one luminous body group which comprises at least two different luminous bodies; a gathering lens mechanism and / or a collimating lens mechanism which are / is used for gathering and / or collimating the light beams emitted by the light source mechanism; and a position adjusting mechanism which comprises a connecting assembly connected with the light source mechanism or the collimating lens mechanism or the furling lens mechanism, a guide structure allowing the connecting assembly to move directionally, and a driving part driving the connecting assembly to move along the guide structure. According to the invention, at least two different luminous bodies are arranged on the light source mechanism, and the position adjusting mechanism is connected with the light source mechanism or the collimating lens mechanism or the folding lens mechanism, so that the collimating lens mechanism or the folding lens mechanism is controlled to generate relative displacement with the light source mechanism, the lens units on the collimating lens mechanism or the folding lens mechanism can be aligned with different light-emitting bodies for collimation or folding, and therefore different light spot effects are achieved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a light source adjustment device. Background technique [0002] Most of the existing stage lighting sources use LED light sources. When the stage light source structure is collimated, the lens unit is aligned with the optical center of the LED chip to achieve the best collimation effect; but the single LED chip presents The light spot effect is a single effect. If you need to achieve a different color temperature, different color or different shape of the light spot effect, you need to replace the light source module, which is time-consuming and labor-intensive, and cannot better meet the current needs. However, if two or more LED chips are set on one chip unit to correspond to the same lens unit, the lens unit cannot be aligned with the optical center of each LED chip for optimal collimation, and the light spots presented The effect cannot meet the stage lighting standard. Th...
