Description

Technical Field

[0001] This utility model relates to the field of detection light source technology, and in particular to a combined programmable light source with adjustable color temperature. Background Technology

[0002] Traditional light sources with high color temperature requirements can only be customized by finely controlling the color temperature of the LED chips. Different color temperature requirements can only be achieved by replacing the LED chips. The same light source cannot be arbitrarily adjusted for color temperature. Moreover, the cost of LED chips with finely controlled color temperature is extremely high, and the customized color temperature is very limited. Therefore, the cost of LED chips for traditional light sources with color temperature requirements is extremely high. Furthermore, the color temperature adjustment of finished light sources is greatly affected by external factors such as the surface treatment of components. The manpower and material resources required for debugging finished LED chips are enormous, and the waste of LED chips is also extremely serious. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a combination programmable light source with adjustable color temperature. This invention allows for arbitrary adjustment of the desired color temperature, making its application more flexible and widespread. Moreover, this light source is designed with a reserved external light source port, allowing for the arbitrary combination of various light sources.

[0004] To achieve the above objectives, this utility model provides an automatic polishing device for irregularly shaped plates, comprising:

[0005] The base plate and the outer shell connected to the base plate are provided with a light outlet on the base plate and a detection inlet on the outer shell;

[0006] A first ring light source, a shadowless light source, a second ring light source, and a coaxial light source are detachably connected from bottom to top on the base plate, and are coaxially arranged with the light outlet and the detection inlet. The first ring light source, the shadowless light source, the second ring light source, and the coaxial light source all use dual-color temperature controllable lamp beads.

[0007] Inside the housing, there is also a first control circuit board and a second control circuit board electrically connected to the first control circuit board. The second control circuit board is used to control the opening and closing of different color temperatures of the dual-color temperature controllable lamp beads of the first ring light source, the shadowless light source, the second ring light source, and the coaxial light source.

[0008] Furthermore, the dual-color temperature controllable LED bead includes an LED bead body, a first LED bead and a second LED bead disposed on the LED bead body, and a first chip and a second chip for controlling the first LED bead and the second LED bead. The LED bead body is provided with a first pin and a second pin that are connected to the first LED bead and the second LED bead, with two sets of each. A dual-color temperature controllable LED bead with high and low color temperatures and two chips and four pins is adopted. This dual-color temperature controllable LED bead consists of one high-color and one low-color white LED bead. In the finished combined light source, a second control circuit board is used to individually control the current of the two light-emitting chips of this LED bead to adjust the brightness of the two chips, thereby achieving color temperature adjustment.

[0009] Furthermore, the first control circuit board is connected to an external panel, on which several reserved external power plugs electrically connected to the first control circuit board are provided. The external panel is fixed to the end of the housing, and a first opening matching the detection inlet is provided on the external panel. Several first connection holes are also provided on the external panel. The reserved outer diameter power plugs allow for the connection of more different light source modules as needed to meet various functional requirements, thereby improving the scalability of this invention.

[0010] Furthermore, a second connecting hole is provided on the side edge of the outer panel, and a third connecting hole matching the second connecting hole is provided on the top side wing of the outer casing. By using the second and third connecting holes in conjunction with screws or other connectors, a detachable connection between the outer panel and the outer casing can be achieved, improving the efficiency of installation and repair.

[0011] Furthermore, the first and second control circuit boards are respectively provided with a second opening and a third opening in the middle, and the first and second control circuit boards are attached to the outside of the coaxial light source through the second and third openings. The shape and diameter of the second and third openings match the shape and outer diameter of the coaxial light source, so that the first and second control circuit boards can be directly inserted into the outer surface of the coaxial light source. They can be bonded or detachably fixed by adhesive or other connectors. This arrangement can effectively improve space utilization and reduce production costs.

[0012] Furthermore, the first ring light source is a low-angle ring light source, and the second ring light source is a high-angle ring light source. The low-angle ring light source (typically <45°) highlights the surface texture and edge contours of the object through side illumination, while the high-angle ring light (typically ≥45°) provides near-vertical illumination, which is more suitable for planar detection and reducing texture interference.

[0013] Furthermore, the shadowless light source is a ring-shaped light source. A connecting ring is provided on the lower side of the shadowless light source, and a fourth connecting hole is provided on the connecting ring. A fifth connecting hole matching the fourth connecting hole is provided at the upper end of the first ring light source. An L-shaped first connector is connected to the upper end of the shadowless light source, and the other end of the first connector is connected to the second ring light source. The connection between the first ring light source and the shadowless light source is achieved through the fourth and fifth connecting holes combined with screws and other connectors. Furthermore, the first connector enables quick connection between the shadowless light source and the second ring light source, thereby achieving a smooth transition from small diameter to large diameter, making the overall arrangement more reasonable, ensuring that each group of light sources does not interfere with each other, and enabling combined and independent operation.

[0014] Furthermore, the coaxial light source is positioned at the upper end of the second annular light source, and the coaxial light source and the second annular light source are connected by a second connector. The second connector enables rapid installation and removal of the coaxial tube and the second annular light source, improving efficiency.

[0015] Furthermore, the side edge of the housing is provided with heat dissipation holes and a cooling fan. These holes and fans effectively dissipate heat, ensuring stable operation of the internal light sources.

[0016] Furthermore, the light outlet is equipped with a dustproof glass to prevent dust from entering the housing and interfering with the operation of the internal light source, thereby effectively improving the working stability of each component.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This invention employs a dual-color-temperature controllable LED bead with two chips and four pins, one high-color-temperature and one low-color-temperature. The bead consists of one high-color-temperature and one low-color-temperature white LED. In the finished combined light source, an internal control board individually controls the current of the two LED chips to adjust their brightness, thereby achieving color temperature adjustment. This allows each individual light source in the combined light source to have its desired color temperature freely adjustable, making its application more flexible and widespread. Furthermore, it includes a reserved external light source port, allowing for various combinations of light sources.

[0019] This invention integrates different light sources, such as ring lights, shadowless lights, and coaxial lights, into a single combined light source to achieve one-step detection of different parts of the same product that require different color temperature light sources. This avoids the waste of cost and time associated with multiple light sources and multiple detection processes, and greatly reduces the cost and time wasted in such high-precision multi-station color temperature detection scenarios.

Detailed Implementation

[0028] The technology of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0031] Please see Figures 1 to 5 An embodiment of this utility model provides a combined programmable light source with adjustable color temperature, comprising:

[0032] The base plate 1 and the housing 2 connected to the base plate 1 have a light outlet 11 on the base plate 1, and a dustproof glass 12 on the light outlet 11 to prevent dust from entering the interior of the housing 2 and interfering with the operation of the internal light source, thereby effectively improving the working stability of each component; a detection inlet 21 is provided at the upper end of the housing 2, such as... Figure 1 As shown, the outer shell 2 in this embodiment is a tubular structure with openings at both the top and bottom. A fifth connecting hole 13 is provided on the bottom plate 1, and a sixth connecting hole 22 matching the fifth connecting hole 13 is provided at the lower end of the outer shell 2. During assembly, the fifth connecting hole 13 and the sixth connecting hole 22 are aligned and then locked by screws or other connecting parts to achieve a detachable connection. To increase the heat dissipation effect inside the outer shell 2, heat dissipation through holes 23 and cooling fans 24 are also provided on the outer shell 2. As shown in the figure, two sets of heat dissipation through holes 23 and two cooling fans 24 are provided on the outer shell 2. The two sets of heat dissipation through holes 23 and two cooling fans 24 are evenly distributed on the outer shell 2 to improve the uniformity of overall heat dissipation and achieve better results.

[0033] On the base plate 1, from bottom to top, there are a first ring light source 3, a shadowless light source 4, a second ring light source 5, and a coaxial light source 6, which are coaxially arranged with the light outlet 11 and the detection inlet 21. The first ring light source 3 is a low-angle ring light source, and the second ring light source 5 is a high-angle ring light source. The low-angle ring light source (usually the angle between the lamp bead and the horizontal plane is less than 45°) highlights the surface texture and edge contour of the object through side illumination, while the high-angle ring light (the angle between the lamp bead and the horizontal plane is ≥45°) is close to vertical illumination, which is more suitable for planar detection and reduces texture interference.

[0034] The connection relationship of the above light sources is as follows: a seventh connecting hole 14 is provided on the base plate 1, and an eighth connecting hole 31 that mates with the seventh connecting hole 14 is provided at the bottom of the first ring light source 3. During assembly, the seventh connecting hole 14 and the eighth connecting hole 31 are connected by screws or other connecting parts to realize the detachable connection between the first ring light source 3 and the base plate 1. The shadowless light source 4 is a ring-shaped shadowless light source 4. A connecting ring body 41 is provided on the lower side of the shadowless light source 4. A fourth connecting hole 42 is provided on the connecting ring body 41. A fifth connecting hole 13 that matches the fourth connecting hole 42 is provided at the upper end of the first ring light source 3. The fourth connecting hole 42 and the fifth connecting hole 13 are aligned and locked by screws or other connections, thereby realizing the detachable placement of the shadowless light source 4 above the first ring light source 3.

[0035] An L-shaped first connector 43 is connected to the upper end of the shadowless light source 4. The other end of the first connector 43 is connected to the second ring light source 5. Specifically, in this embodiment, a total of four first connectors 43 are provided. The four first connectors 43 are evenly distributed on the upper end of the shadowless light source 4 and are locked to the upper end of the shadowless light source 4 by screws or other connectors. The other end of the first connector 43 is uniformly locked to the side edge of the second ring light source 5 by screws or other connectors. The coaxial light source 6 is placed on the upper end of the second ring light source 5. The coaxial light source 6 and the second ring light source 5 are connected by a second connector 51. The coaxial light source 6 is square. Therefore, when the coaxial light source 6 is installed on the upper end of the second ring light source 5, the upper end of the second ring light source 5 has a space not covered by the coaxial light source 6. The structure of the second connector 51 is the same as that of the first connector 43. Both are in an L-shape. During assembly, one end of the second connector 51 is locked to the upper end of the second ring light source 5 by screws or other connectors, and the other end is locked to the side wall of the coaxial light source 6.

[0036] The above connections achieve a bottom-up stacked arrangement of the first ring light source 3, the shadowless light source 4, the second ring light source 5, and the coaxial light source 6. Figure 2As shown, to ensure that each light source can operate normally and accurately without interfering with each other, the first annular light source 3 is provided with a first annular light outlet 32 ​​and a first annular light inlet 33; the shadowless light source 4 is provided with a shadowless light outlet 44 and a shadowless light inlet 45; the second annular light source 5 is provided with a second annular light inlet 52 and a second annular light outlet 53; and the coaxial light source 6 is provided with a coaxial light outlet 61 and a coaxial light inlet 62. The first annular light outlet 32 ​​is adjacent to the light outlet 11 of the base plate 1, and the first annular light outlet 32 ​​is adjacent to the light outlet 11 of the base plate 1. The diameter of the annular light outlet 32 ​​can be less than or equal to the diameter of the light outlet 11 to ensure the stability of the overall light output. The diameter of the first annular light inlet 33 is less than the diameter of the first annular light outlet 32, and the diameter of the first annular light inlet 33 is greater than the diameter of the shadowless light outlet 44. The diameters of the shadowless light outlet 44, the shadowless light inlet 45, and the second annular light outlet 53 are the same. The diameters of the second annular light inlet 52, the coaxial light outlet 61, the coaxial light inlet 62, and the detection entrance 21 are the same.

[0037] In this embodiment, the first ring light source 3, the shadowless light source 4, the second ring light source 5, and the coaxial light source 6 all use dual-color temperature controllable LED beads 9. Inside the housing 2, there is also a first control circuit board 7 and a second control circuit board 8 electrically connected to the first control circuit board 7. The second control circuit board 8 is used to control the opening and closing of different color temperatures of the dual-color temperature controllable LED beads 9 of the first ring light source 3, the shadowless light source 4, the second ring light source 5, and the coaxial light source 6.

[0038] To improve the space utilization inside the housing 2, preferably, a second opening 71 and a third opening 81 are respectively provided in the middle of the first control circuit board 7 and the second control circuit board 8. The first control circuit board 7 and the second control circuit board 8 are hung on the outside of the coaxial light source 6 through the second opening 71 and the third opening 81. The shape and diameter of the second opening 71 and the third opening 81 match the shape and outer diameter of the coaxial light source 6, so that the first control circuit board 7 and the second control circuit board 8 can be directly inserted into the outer surface of the coaxial light source 6. They can be glued or detachably fixed by means of glue or other connectors. This arrangement can effectively improve the space utilization and reduce the production cost.

[0039] like Figure 5 As shown, the dual-color-temperature controllable LED bead 9 of this embodiment includes an LED bead body 91, a first LED bead 92 and a second LED bead 93 disposed on the LED bead body 91, and a first chip and a second chip (not shown in the figure) for controlling the first LED bead 92 and the second LED bead 93. The LED bead body 91 is provided with a first pin 94 and a second pin 95 that are connected to the first LED bead 92 and the second LED bead 93. The first LED bead 92 and the second LED bead 93 are white LED beads with one high color temperature and one low color temperature. That is, one of the first LED bead 92 and the second LED bead 93 is a high color temperature LED bead with a color temperature of 5000K or higher, and the other is a low color temperature LED bead with a color temperature of less than 3500K.

[0040] Furthermore, as a preferred embodiment, this application also provides a structure for expanding other light sources. Specifically, the first control circuit board 7 is connected to an external panel 72, and the external panel 72 is provided with several reserved external power plugs 721 that are electrically connected to the first control circuit board 7. The first control circuit board 7 is provided with a communication network port 73. The external panel 72 is fixed to the end of the outer shell 2, and the external panel 72 is provided with a first opening 722 that matches the detection inlet 21. The external panel 72 is provided with several first connection holes 723 for connecting and cooperating with subsequently added light sources. In addition, the side edge of the external panel 72 is provided with a second connection hole 724, and the top side wing of the outer shell 2 is provided with a third connection hole 25 that matches the second connection hole 724. By setting the external panel 72 at the top of the outer shell 2, and with the reserved external power plugs 721 and communication network ports 73, more different light source modules can be connected as needed to meet various functional requirements, thereby improving the expandability of this utility model.

[0041] This invention controls the start and stop of each component through the first control circuit board 7, and controls the current of the first chip and the second chip through the second control circuit board 8 to adjust the brightness of the two chips, thereby achieving color temperature adjustment. In addition, the light source module of this invention uses the above-mentioned dual color temperature controllable LED beads 9 as the light source. Thus, each individual light source can be adjusted to the desired color temperature at will through the second control circuit board 8, making the application scenarios more flexible and extensive. Furthermore, a reserved external light source port has been added, which can be freely combined with various light sources.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
