[0002] In the field of stage lighting, stage cutting lights equipped with white light modules usually use display index (CRI) and color temperature (CCT) filters to adjust the display index and color temperature. Although this method has a wide range of adjustment types and strong applicability, it suffers from large light losses when passing through the CRI and CCT filters, resulting in a significant reduction in light efficiency and large light color drift after filtering. In addition, the CRI and CCT filters require independent module control, which increases product costs. Utility Model Content

[0034] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0035] like Figure 1-Figure 3 As shown, the utility model is a high-brightness light source module that can freely switch between two color temperatures or two color rendering indices, including:

[0036] A substrate 1, on which two chips 5 with different color temperatures or different display indexes are welded, and a motion bracket 6 is connected;

[0037] A lens array module 2, wherein the lens array module 2 is mounted on a motion bracket 6 via a linear bearing structure;

[0038] The motor assembly 3 is fixed to the motion bracket 6, and the driving end of the motor assembly 3 is connected to the lens array module 2, and the lens array module 2 is driven to move by the motor assembly 3;

[0039] The optical component 4 is fixed on the moving bracket 6.

[0040] The lens array module 2 includes an array support 7 and an array lens 8; the array lens 8 is mounted on the array support 7;

[0041] The linear bearing structure includes a bearing seat 9, a bearing body 10 and a bearing rod 11 arranged on the array bracket 7; the bearing rod 11 is located in the grooves on both sides of the moving bracket 6, the bearing body 10 is arranged on the bearing seat 9, and the bearing rod 11 is placed on the inner side of the bearing body 10; the bearing is fixed by a bearing cover 12; the lens array module slides back and forth through the linear bearing structure, and the sliding resistance is small.

[0042] The motor assembly 3 includes a motor body 13, a motor bracket 14 and a screw rod 15;

[0043] The motor body 13 is mounted on a motor bracket 14, and the motor bracket 14 is connected to the motion bracket 6; a screw rod 15 is mounted on the output shaft of the motor body 13, and a slider 16 is mounted on the screw rod 15; limit switches 17 are provided at both ends of the slider 16, and the limit switches 17 are fixed to the motor bracket 14;

[0044] The motor drives the lead screw to rotate, and the lead screw converts the rotational motion of the screw thread into direct motion to push the slider to move. The slider pushes the lens array assembly forward or backward to touch the edge of the motion bracket. At this time, the designated chip and lens array assembly are aligned. After reaching the designated position, the slider will stop after touching the limit switch with a delay, and the lamp will light up (touching the limit switch will send a command to the driver power supply, and the driver power supply will stop supplying power to the motor. At this time, the aligned chip will light up; if it needs to move to the other side, the driver power supply will receive the command again and the driver power supply will move until it touches the limit switch again and stops).

[0045] The optical assembly 4 includes a housing 18, a light output mirror 19, a pressure ring 20, a homogenizing mirror 21 and a homogenizing mirror bracket 22;

[0046] The light-emitting mirror 19 is installed in the outer shell 18 through the pressure ring 20, and the homogenizer 21 is respectively installed above and below the homogenizer bracket 22, and is fixed to the bottom of the outer shell 18 by locking screws; the outer shell 18 is fixed to the motion bracket 6 by screws; a avoidance groove is provided on the side of the outer shell 18, and the motor assembly 3 is located at the avoidance groove.

[0047] The motor assembly 3 is exposed to ensure good heat dissipation of the motor and does not cause the torque of the motor body to drop due to high temperature.

[0048] Among them, a C-shaped mounting seat 23 is provided on the lens array module 2, and spring columns 24 are installed on both sides of the mounting seat 23, and the spring columns 24 correspond to the positions of the slider 16; the spring columns 24 are plugged with springs, and the springs press the column heads. When pushed by the slider 16, the column heads will shrink after exceeding the spring elastic force; the purpose of shrinkage is to ensure that the array lens assembly stops first and then the motor stops.

[0049] The array lens assembly uses a slider to push the spring plunger on the array lens assembly to the edge of the moving bracket. To ensure that the motor stops after it touches the bracket edge first and then hits the limit switch, the slider first pushes the spring plunger to the edge. At this time, the slider compresses the spring plunger's head (which has a certain amount of travel to compress) while the array lens assembly stops moving. The motor stops only after the spring plunger has been compressed a certain distance and hits the limit switch. This is mainly intended to solve the problem of out-of-position (Idle) during the movement of the array lens (the motor stops before touching the edge).

[0050] In addition, the circuit board is equipped with limit switch circuits, and the limit switches and wires are built into the module, which is beautiful and practical.

[0051] In addition, a glue dispensing hole is provided on the bearing seat 9, and glue is dispensed through the glue dispensing hole to prevent the bearing from being loose.

[0052] like Figure 4 As shown, the substrate 1 welds every two chips 5 together closely, and lamp beads with different color temperatures or different display indexes are made on the two chips 5 through a packaging process, and then arranged in equidistant hexagons on the substrate 1 to reduce the movement range of the array lens assembly and increase the movement accuracy.

[0053] In addition, sealing rings are provided between the motor body 13 and the housing 18 , the motor body 13 and the motor bracket 14 , the substrate 1 and the motion bracket 6 , and the housing 18 and the motion bracket 6 .

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
