In the present embodiment, at least two different light emitters are disposed on the light source mechanism 10, and at least one of the color, color temperature, number, shape, and light emitting power of the different light emitters is different, so that the light source mechanism 10 can emit at least two different light beams, and the present embodiment is connected to the light source mechanism 10, or the collimating lens mechanism 20, or the collecting lens mechanism 60 by the position adjusting mechanism 30, so as to control the relative displacement between the collimating lens mechanism 20 and/or the collecting lens mechanism 60 and the light source mechanism 10, so that the lens unit on the collimating lens mechanism 20 can align with the different light emitters for collimation, and/or the lens unit on the collecting lens mechanism can align with the different light emitters for collecting light, thereby achieving different light spot effects.

Specifically, the light emitting body of the present embodiment may be a single chip, multiple chips, or a lamp bead, the chip may be a bare chip or a packaged chip, and the chip type may be an LED chip or a VCSEL.

Example 1

In the present embodiment, each light emitting device group 11 includes two different light emitting devices, and the position adjusting mechanism 30 is connected to the collimating lens mechanism 20, but in other embodiments, more than two different light emitting devices may be included, and the position adjusting mechanism 30 may be connected to the light source mechanism 10, or the position adjusting mechanism 30 may be connected to the collecting lens mechanism 60. When the light source adjusting device 100 of the present embodiment is located at the initial position, the collimating lens mechanism 20 is located at the first position, the lens unit of the collimating lens mechanism 20 aligns with the first light-emitting body and collimates the light beam emitted therefrom, and when the light spot effect needs to be changed, the driving member 33 drives the first fixing assembly to displace along the axial direction of the first shaft assembly 32, so that the collimating lens mechanism 20 is located at the second position, and the lens unit of the collimating lens mechanism 20 aligns with the second light-emitting body and collimates the light beam emitted therefrom, thereby implementing the second light spot effect. Similarly, in other embodiments, if the mth light spot effect is to be achieved, the driving assembly 33 drives the collimating lens mechanism 20 to be located at the mth position, so that the lens unit is aligned with the mth illuminant.

In this embodiment, the distance between the optical centers of the two different illuminants is the same as the sliding stroke of the first fixing base assembly 31, so that when the first fixing base assembly 31 is located at the two limit positions, the lens unit of the collimating lens mechanism 20 is just aligned to the two different illuminants, thereby facilitating the limit control.

The first optical axis 321 is fixed on a frame or a substrate of the light source system through a first fixing frame 322, wherein the frame or the substrate is used for carrying or integrating various mechanisms or components of the light source system. The first fixing seat assembly 31 is inserted into and matched with the first optical axis 321, so as to be slidable along the axial direction of the first optical axis 321; and a first linear bearing is arranged between the first fixed base assembly 31 and the first optical axis 321, so that the first fixed base assembly 31 can realize stable linear motion with high sensitivity and high precision.

In addition, since the optical center distance between different illuminants is short, in order to improve the displacement accuracy of the collimating lens mechanism 20 to align the optical centers of the different illuminants, the light source adjusting device 100 further includes a first limiting unit that limits the sliding stroke of the first mount assembly 31; further, a first limiting unit for limiting the sliding stroke of the first fixing base assembly 31 is disposed on the first fixing base 322.

The first stoppers 323 at two sides respectively limit two limit positions of the first fixing base assembly 31 during movement, so that the collimating lens mechanism 20 is respectively located at the first position and the second position, thereby realizing collimation of two kinds of light-emitting bodies.

In addition, in order to assist the sliding of the collimator lens mechanism 20, to make the sliding of the collimator lens mechanism 20 smooth and smooth, and to ensure the sliding accuracy, the position adjustment mechanism 30 further includes a guide unit 40 for guiding the displacement of the light source mechanism 10 or the collimator lens mechanism 20. Similarly, when the position adjusting mechanism 30 is connected to the lens retracting mechanism 60, the position adjusting mechanism further includes a guide unit for guiding the displacement of the lens retracting mechanism 60.

As shown in fig. 1 and 2 in conjunction with fig. 6 to 8, the guide unit 40 of the present embodiment includes a second holder assembly 41 connected to the light source mechanism 10 or the collimator lens mechanism 20, and a second shaft assembly 42 slidably connected to the second holder assembly 41, so that the collimator lens mechanism 20 is displaceable in an axial direction of the second shaft assembly 42; the second mount assembly 41 and the first mount assembly 31 are located on different sides of the light source mechanism 10 or the collimator lens mechanism 20, respectively. In other embodiments, the second holder assembly 41 can be connected to the furled lens mechanism 60, and the second holder assembly 41 and the first holder assembly 31 are located on different sides of the furled lens mechanism 60.

Specifically, in the present embodiment, the second mount assembly 41 and the first mount assembly 31 are respectively disposed on two opposite sides of the light source mechanism 10 or the collimating lens mechanism 20, and the axial direction of the second shaft assembly 42 is parallel to the axial direction of the first shaft assembly 32. In other embodiments, the first and second fixing base assemblies 31 and 41 may be disposed at adjacent sides of the collimating lens mechanism 20, and the axial direction of the second shaft assembly 42 and the axial direction of the first shaft assembly 32 may be adjusted accordingly.

Specifically, the second shaft assembly 42 includes a second optical axis 421 slidably fitted with the second holder assembly 41, and a second holder 422 for fixing the second optical axis 421. The second optical axis 421 is fixed on a frame or a substrate of the light source system by a second fixing frame 422, and the second fixing base assembly 41 is inserted into and matched with the second optical axis 421, so as to be slidable along the axial direction of the second optical axis 421; and a second linear bearing is arranged between the second fixed base assembly 41 and the second optical axis 421, so that the second fixed base assembly 41 can realize stable linear motion with high sensitivity and high precision.

In order to improve the precision of the auxiliary sliding, the light source adjusting apparatus 100 further includes a second limiting unit for limiting the sliding stroke of the second fixing base assembly 41.

The second stoppers 423 at both sides respectively limit the two limit positions of the second fixed base assembly 41 during movement.

In addition, if the stroke ranges of the first and second fixed- seat assemblies 31 and 41 are consistent, when there is an assembly error in the assembly process of the guide unit 40, the movable stroke of the entire position adjustment mechanism 30 will be smaller than the stroke defined by the first limit unit, so in this embodiment, the sliding stroke of the second fixed-seat assembly 41 is set to be larger than the sliding stroke of the first fixed-seat assembly 31, that is, the distance between the two second limit blocks 423 is larger than the distance between the two first limit blocks 323.

Specifically, the sliding stroke of the first fixed seat assembly 31 is L, and the sliding stroke of the second fixed seat assembly 41 is L + n, where n ranges from 1mm to 5 mm.

In this embodiment, the driving member 33 is a solenoid valve, an electromagnetic chuck or a stepping motor, and can drive the first fixing base assembly 31 to displace. In other embodiments, the driving member may be a manual type, such as a push rod or a lead screw, for adjusting the relative positions of the collimator lens mechanism 20 and the light source mechanism 10 through a manual control manner, wherein the manual type includes, but is not limited to, a hand-push type and a hand-operated type, and accordingly, a positioning member for the push rod or the lead screw may be added to the manual type, so that the collimator lens mechanism 20 can be aligned with the optical centers of different illuminants.

Specifically, the driving assembly 33 of the present embodiment includes two electromagnetic valve units 331, and the two electromagnetic valve units 331 are respectively connected to two opposite sides of the first fixing assembly, so that the two electromagnetic valve units 331 can respectively drive the first fixing assembly to move in a first direction and a second direction opposite to each other, so as to implement the reciprocating motion of the first fixing assembly, and drive the position adjusting mechanism 30 to switch between the first position and the second position, thereby implementing two different light spot effects.

In this embodiment, the light source mechanism 10 is provided with light emitting groups 11 arranged in an array, and each light emitting group 11 includes 2 light emitting bodies. In other embodiments, each group of luminary groups 11 may also include more than 2 luminaries. In other embodiments, the light groups 11 may not be identical, for example, most of the light groups 11 are composed of two kinds of lights, and each of the light groups located at the edge is provided with only one light or each of the light groups or light groups located at the center is provided with only one light.

In the embodiment, the luminous body is a single LED chip; in other embodiments, the light emitter may include at least two LED chips arranged linearly, or the light emitter includes a plurality of LED chips arranged in an array, or the light emitter is a packaged LED chip. The different LED chips can be LED chips with different colors, can also be LED chips with different color temperatures, and can also be LED chips with different luminous powers.

As shown in fig. 5, the first fixing base assembly 31 of this embodiment includes a bushing 311 for slidably connecting with the first shaft assembly 32, and a connecting member 312 connected with the bushing 311 and for fixedly connecting with the collimating lens mechanism 20; the bushing 311 is inserted and engaged with the first shaft assembly 32.

In order to improve the connection strength between the first fixing seat assembly 31 and the collimator lens mechanism 20 and prevent the collimator lens mechanism 20 from shaking or jumping during the displacement process to affect the displacement precision, thereby affecting the collimating effect, the connecting member 312 of the present embodiment includes a first limiting portion 3121 for performing a first-direction limiting on the collimator lens mechanism 20, and a second limiting portion 3122 for performing a second-direction limiting on the collimator lens mechanism 20; the second direction and the first direction form an included angle with each other, so that the collimating lens mechanism 20 can be aligned in different directions for limiting, and the reliability and stability of the connection between the collimating lens mechanism 20 and the connecting piece 312 are further ensured.

Preferably, in the present embodiment, the second direction is perpendicular to the first direction, that is, the up-and-down movement and the left-and-right movement of the collimator lens mechanism 20 are limited by the first direction and the second direction, respectively.

Specifically, the connecting member 312 of the present embodiment includes a connecting plate connected to the shaft sleeve 311 and provided with a connecting hole, and a locking groove engaged with the collimator lens mechanism 20.

The connecting plate is provided with two connecting holes which are connected with the collimating lens mechanism 20 through bolts or screws, and the axes of the two connecting holes are perpendicular to the displacement direction of the collimating lens mechanism 20, so that the up-and-down movement of the collimating lens mechanism 20 is limited after the screws are screwed down. The width of the clamping groove is matched with the width of the connecting part of the collimating lens mechanism 20, so that the collimating lens mechanism 20 is prevented from shaking left and right.

Further, the connecting plate of this embodiment is located below the collimator lens mechanism 20 and is used for bearing the collimator lens mechanism 20, so as to balance and share the filling stress of the collimator lens mechanism 20 on the first mount assembly 31, so that the connection between the first mount assembly 31 and the collimator lens mechanism 20 is more stable, and deformation of the first mount assembly 31 and the collimator lens mechanism 20 due to connection stress concentration is avoided.

The third limiting unit 50 is a solenoid valve push rod, and when the solenoid valve is powered on, the extension and retraction degree of the push rod can be controlled, and the extension and retraction direction of the push rod is consistent with the displacement direction of the collimating lens mechanism 20, so that when the collimating lens mechanism 20 is displaced to the second fixing seat component 41 to abut against the push rod, the collimator lens mechanism cannot be displaced continuously, the collimating lens mechanism 20 is stopped at the position limited by the push rod, and is aligned with the optical center of the third illuminant or the mth illuminant, thereby realizing the collimation of three or more different illuminants.
