Description

Technical Field

[0001] The utility model relates to the technical field of annular light sources, in particular to a fan-shaped annular light source with good heat dissipation, high brightness and high power. Background Art

[0002] The fan-shaped ring light source has a fan-shaped structure and is a special type of ring light source.

[0003] In the field of machine vision, the design of fan-shaped ring light sources helps reduce shadows caused by uneven object surfaces or multi-directional lighting, providing clearer and higher-contrast images. The fan-shaped ring light source provides uniform light through its specific fan-shaped design, which can effectively illuminate a certain area of ​​the object to be measured, improving the brightness of the object to be measured, enabling the image processing system to better capture details. Multiple fan-shaped ring light sources can also be used together to solve problems such as insufficient space when the structure of the mechanism is relatively special.

[0004] However, the current fan-shaped ring light source has the following structural defects:

[0005] 1. When manufacturing a fan-shaped ring light source, a flat curved PCB circuit board is bent and then glued to the fan-shaped side wall of the fan-shaped groove of the fan-shaped ring light source. However, during the manufacturing process, it is impossible to bend the curved PCB circuit board to be completely consistent with the fan-shaped side wall. This easily results in the curved PCB circuit board not being able to fit tightly against the fan-shaped side wall, and thus it is impossible to ensure that the curved PCB circuit board effectively dissipates heat to the fan-shaped side wall of the fan-shaped ring light source. Ultimately, the curved PCB circuit board heats up and accumulates heat in the fan-shaped groove, causing the fan-shaped ring light source to heat up;

[0006] 2. The fan-shaped ring light source has no heat dissipation unit, so it cannot dissipate heat well, causing the fan-shaped ring light source to heat up.

[0007] The above two defects will cause heat accumulation and poor heat dissipation performance of the fan-shaped ring light source, which will eventually lead to the fan-shaped ring light source being unable to operate at high power and high brightness, otherwise the fan-shaped ring light source will be easily damaged. Utility Model Content

[0008] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and to provide a fan-shaped ring light source with good heat dissipation, high brightness and high power, so as to solve the problems of poor heat dissipation, low power and low brightness of the existing fan-shaped ring light sources.

[0009] To achieve the above objectives, the utility model provides a fan-shaped ring light source with good heat dissipation, high brightness and high power, including an arc-shaped base, an arc-shaped groove is opened inside one side of the arc-shaped base, and a side wall of the arc-shaped groove is provided with a plurality of connected mounting planes, a PCB circuit board is provided on the mounting plane, an LED chip assembly is mounted on the PCB circuit board, and a plurality of heat dissipation units are installed at the bottom of the arc-shaped base.

[0018] Preferably, an external power supply head is installed on the outside of the cable management trough.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The utility model is provided with an arc-shaped seat, and an arc-shaped groove is formed inside the arc-shaped seat. One side wall of the arc-shaped groove is composed of several connected mounting planes.

[0022] 3. In summary, the utility model provides a fan-shaped ring light source with good heat dissipation, high brightness and high power.

[0023] First, by converting one side wall of the arc groove into several connected mounting planes, the PCB circuit board is completely mounted on the mounting plane, thereby effectively conducting away the heat emitted by the PCB circuit board and avoiding heat accumulation inside the arc groove;

[0024] Secondly, further, a heat dissipation unit is provided at the bottom of the arc seat to dissipate heat, so that the heat in the arc groove is dissipated to the external environment of the arc seat more quickly;

[0035] See also Figures 1 to 5 The embodiment of the utility model provides a fan-shaped ring light source with good heat dissipation, high brightness and high power, including an arc seat 1, an arc groove 2 is opened inside one side of the arc seat 1, and a side wall of the arc groove 2 is provided with a plurality of connected mounting planes 3, a PCB circuit board 4 is provided on the mounting plane 3, an LED chip assembly 5 is mounted on the PCB circuit board 4, and a plurality of heat dissipation units 6 are installed at the bottom of the arc seat 1.

[0036] The mounting planes 3 are arranged at a certain inclination angle. In addition, a first chamfered surface 30 is provided between two adjacent mounting planes 3. Several mounting planes 3 and their adjacent first chamfered surfaces 30 together form a side wall of the arc-shaped groove 2.

[0037] The PCB circuit board 4 and the mounting plane 3 are connected together by bolts. By tightening the bolts, the PCB circuit board 4 is ensured to be completely attached to the mounting plane 3, so that the PCB circuit board 4 can effectively conduct heat to the mounting plane 3.

[0038] The heat dissipation unit 6 is a heat dissipation fan.

[0039] The arc base 1 includes an arc base 11, a cover plate 12 mounted on top of the arc base 11, a first end plate 13 mounted on one side of the arc base 11, a second end plate 14 mounted on the other side of the arc base 11, and a diffuser 15 mounted on top of the cover plate 12. The enclosed space formed by the arc base 11, cover plate 12, first end plate 13, second end plate 14, and diffuser 15 constitutes the arc groove 2. The function of the diffuser 15 is to evenly disperse the light source concentrated at the center of the arc by the LED chip assembly 5 on the PCB circuit board 4, ensuring a uniform light source.

[0040] The arc-shaped base 11 includes an upper arc-shaped body 111 and a lower heat dissipation base 112 mounted on the bottom of the upper arc-shaped body 111 . A plurality of heat dissipation units 6 are evenly arranged around the bottom of the lower heat dissipation base 112 .

[0041] The lower heat dissipation base 112 includes a plurality of evenly arranged heat dissipation fins 1120. The evenly arranged heat dissipation fins 1120 can effectively increase the heat dissipation area and ensure rapid heat dissipation.

[0042] A wire management groove 70 is defined between the arc-shaped base 11 and the cover plate 12 and is in communication with the arc-shaped groove 2 and the outer side of the arc-shaped base 11 . The wire management groove 70 allows the external power supply head 7 to pass through the arc-shaped groove 2 .

[0043] An external power connector 7 is installed outside the cable management slot 70. The external power connector 7 is electrically connected to a plurality of PCB circuit boards 4 respectively.

[0044] The light-emitting principle of the fan-shaped ring light source of the present invention, which has good heat dissipation, high brightness and high power, is as follows: a plurality of LED chip assemblies 5 on a PCB circuit board 4 emit light to the center of the arc and hit the inner side of a diffuser 15. The diffuser 15 evenly emits the light to a certain part of the object to be measured, so as to achieve a certain part of the object to be measured with high and more uniform lighting and contrast.

[0045] The heat dissipation principle of the fan-shaped ring light source with good heat dissipation, high brightness and high power of the present invention is as follows: when a number of LED chip components 5 emit light, a number of PCB circuit boards 4 generate heat, and each PCB circuit board 4 directly conducts the heat to the mounting plane 3 to which it is closely attached. The heat on the mounting plane 3 is transferred to the outer wall of the upper arc-shaped body 111 and the lower heat dissipation base 112. The lower heat dissipation base 112 has multiple heat dissipation fins 1120, which can effectively increase the heat dissipation area. When combined with the heat dissipation unit 6, it can quickly bring the heat to the outside to ensure good heat dissipation performance inside the arc groove 2, thereby achieving greater heating power and higher brightness.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
