Abstract
Description
Technical Field
[0001] This utility model relates to the field of imaging light source technology, and in particular to a parallel imaging light source emitting device. Background Technology
[0002] During the imaging process, when the target object is far away from the light source (more than 1 meter), the light will be significantly lost after reaching the target object because the existing light source is not a parallel light source, resulting in poor image quality.
[0003] To obtain clear photos and reduce light loss, the only option is to increase the intensity and power of the light source, which leads to severe heat generation. At the same time, due to inefficient heat dissipation design, the heat inside the light source cannot be dissipated in time, resulting in a significant reduction in the lifespan of the LED chips.
[0004] Therefore, how to design a parallel imaging light source emitting device with high uniformity, high intensity, high heat dissipation and long life is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] This invention provides a parallel imaging light source emitting device, which solves the technical problems of poor uniformity, severe loss during transmission, and short lifespan of existing imaging light sources.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a parallel imaging light source emitting device includes: a first fixing base, a circuit board, a second fixing base, and a reflective film. One side of the circuit board is fixed parallel to one side of the first fixing base, and a plurality of LED beads are fixed at intervals on the other side of the circuit board. The second fixing base is located on the side of the first fixing base corresponding to the plurality of LED beads, and the side of the second fixing base corresponding to the first fixing base is a concave arc surface. The arc direction of the concave arc surface is arranged along the height direction of the first fixing base. The reflective film is attached to the concave arc surface along the arc direction of the concave arc surface and is arranged opposite to the plurality of LED beads to reflect the scattered light emitted by the plurality of LED beads into parallel light.
[0007] The beneficial effects of this utility model are: it improves the traditional imaging light source emitting device by using multiple LED beads and a reflective film arranged in a relative manner. Since the reflective film is arranged along the arc direction of the concave arc surface, the heat dissipation light emitted by multiple LED beads can be transformed into parallel light, which greatly improves the effective utilization rate of light. Compared with the original ordinary light source, it can present a stronger light effect when illuminating at a distance. At the same time, under the same light intensity, it can reduce power consumption, reduce heat generation of the light source, enhance heat dissipation, and extend service life.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, it also includes a constant current source controller, which is electrically connected to the plurality of LED beads through the circuit board.
[0010] A further benefit of the above is that the constant current controller provides a power interface, and the brightness and on / off buttons control the brightness and on / off state of multiple LED beads.
[0011] Furthermore, it also includes a fixing bolt, wherein the first fixing seat has a fixing hole corresponding to the lower part of the circuit board; the second fixing seat has a threaded hole corresponding to the lower part of one side of the concave arc surface, and the threaded hole is arranged opposite to the fixing hole; the fixing bolt passes through the fixing hole and is threaded into the threaded hole.
[0012] Furthermore, it also includes a lampshade, which covers the plurality of LED beads and has its open end fixed to one side of the first fixing base.
[0013] Furthermore, the angle between the direction of the light emitted by the plurality of LEDs and the vertical direction of the concave arc-shaped surface is 22 to 122°.
[0014] Furthermore, the power lines on the circuit board are all made of copper.
[0015] The further beneficial effects of adopting the above are: all power lines on the circuit board are made of copper, which can reduce line voltage drop, obtain uniform light, improve heat dissipation, and extend the life of the light source. Attached Figure Description
