Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0040] Please see the attached Figures 1 to 8, an embodiment of the utility model provides a light source device, comprising: a lamp board 1, on which a light-emitting element 11 is provided; a lens 2, wherein the light-incoming side cover of the lens 2 is provided on the light-emitting element 11, and the light emitted by the light-emitting element 11 passes through the lens 2 to be emitted from the light-emitting side of the lens 2; wherein the lens 2 comprises a lens portion 21, and a first surrounding seat 22 and a second surrounding seat 23 respectively extending on both axial sides of the lens portion 21, the first surrounding seat 22 is located on the light-incoming side of the lens 2, the first surrounding seat 22, the lens portion 21 and the lamp board 1 together form a light-incoming groove 221 for accommodating the light-emitting element 11; the second surrounding seat 23 is located on the light-emitting side of the lens 2, the second surrounding seat 23 and the lens portion 21 together form a light-emitting groove 231, the side of the lens portion 21 facing the light-incoming groove 221 is flat, and the side of the lens portion 21 facing the light-emitting groove 231 is beaded. It should be explained that the light-emitting element 11 and the lens 2 in this embodiment are adapted to each other. The size of the lens 2 is designed to match the size of the light-emitting element 11 to improve the luminous efficiency of the light-emitting element 11 and achieve the best lighting effect and service life. It is understandable that the side of the lens portion 21 facing the light inlet groove 221 is flat, which facilitates receiving the light emitted by the light-emitting element 11, while the side of the lens portion 21 facing the light outlet groove 231 is beaded, which can change the propagation direction of the light, making the light more concentrated and directional, thereby improving the luminous efficiency. In addition, the first and second surrounding seats 22 and 23 respectively enclose the lens portion 21 to form the light inlet groove 221 and the light outlet groove 231, which play the role of fixing and protecting the light-emitting element 11, while also ensuring the effective transmission of light within the lens 2. In actual application, the light-emitting element 11 of this embodiment is precisely installed on the lamp board 1, and the first surrounding seat 22 of the lens 2 and the lamp board 1 enclose a light groove 221, completely covering the light-emitting element 11. When the light-emitting element 11 emits light, the light first passes through the plane side of the lens portion 21 into the interior of the lens 2, and then is refracted and focused by the bead-shaped light-emitting side, and finally emitted from the light-emitting groove 231 in a more concentrated and directional manner, so that the luminous efficiency can be improved without increasing the number of LEDs or increasing the power of a single LED, thereby avoiding an increase in the volume of the device.

[0041] Specifically, the light emitting element 11 is a 7070 lamp bead.

[0042] Furthermore, it also includes a strobe controller, which is electrically connected to the lamp board 1 and is used to control the light-emitting element 11 to flash. When the strobe controller is working, it controls the light-emitting element 11 to perform a flash action with a flash time every waiting time. The waiting time is 15ms and the flash time is 1ms. When the light-emitting element 11 is in the waiting time, the light-emitting element 11 works at its rated power. When the light-emitting element 11 is in the flash time, the actual power of the light-emitting element 11 is four times its rated power. It can be understood that this embodiment uses a strobe brightening method to increase the power of the light source device at the normal rated power instant. In this process, the human eye cannot capture the moment when the light source device turns on and off. The visual effect is that it is always on, thereby achieving a high-brightness state. Optionally, the strobe controller is a PM-S-48W200-4T strobe controller.

[0043] In this embodiment, the strobe controller is electrically connected to the light board 1 and can periodically adjust the power of the light-emitting element 11. By controlling the light-emitting element 11 to alternate between a low-power waiting time and a high-power flashing time in each cycle, during the waiting time (15ms), the light-emitting element 11 operates at its rated power, while during the flashing time (1ms), the actual power of the light-emitting element 11 is instantly increased to four times its rated power. Due to the persistence of vision effect of the human eye, this rapid power change is visually smoothed into continuous high-brightness lighting. It should be explained that this solution achieves a visually continuous high-brightness effect through stroboscopic brightening, meeting the needs of specific application scenarios. Although the power of the light-emitting element 11 is high during the flashing time, due to its extremely short duration, the overall energy consumption remains at a relatively low level. In addition, the light-emitting element 11 operates at rated power most of the time, reducing overheating and loss caused by long-term high-power operation, thereby extending the service life of the light-emitting element 11.

[0044] Furthermore, it also includes a mounting box 3, in which the lamp board 1, the light-emitting element 11, and the lens 2 are all arranged. The mounting box 3 is provided with an air-avoidance hole 321 corresponding to the light-emitting groove 231. Through the design of the mounting box 3, this embodiment realizes the effective integration and packaging of components such as the lamp board 1, the light-emitting element 11 and the lens 2, thereby improving the integration and compactness of the light source device. At the same time, the mounting box 3 provides good protection for the light source device, which can prevent interference and damage from the external environment such as dust and moisture, thereby extending the service life of the light source device. Preferably, the mounting box 3 is provided with a heat dissipation structure or material, such as a heat sink, a heat dissipation fan or a thermal conductive adhesive, so as to improve the heat dissipation performance of the light source device and ensure that it does not cause overheating problems when operating at high power.

[0045] Further, the mounting box 3 comprises a base 31 and a cover plate 32, the base 31 is provided with a mounting groove 33, the lamp plate 1 is arranged in the mounting groove 33, the light emitting element 11 and the lens 2 are arranged on the side of the lamp plate 1 facing the slot of the mounting groove 33, the cover plate 32 is connected to the slot of the mounting groove 33, and the clearance hole 321 is arranged on the cover plate 32; the side of the clearance hole 321 facing the lens 2 is outwardly provided with an annular alignment groove, the first surrounding seat 22 abuts against the lamp plate 1, and the second surrounding seat 23 abuts against the annular alignment groove. It can be understood that the base 31 and the cover plate 32 are two independent modules connected together by screws or buckles to form a complete mounting box 3 structure, wherein the mounting groove 33 is used to accommodate and fix the lamp plate 1, the annular alignment groove is used to accurately align and fix the lens 2, and the first surrounding seat 22 and the second surrounding seat 23 abut against the lamp plate 1 and the annular alignment groove respectively, further enhancing the connection stability and assembly precision between components.

[0046] Optionally, the base 31 comprises a bottom shell 311 arranged in a U shape, and a left shell 312 and a right shell 313 connected to the openings of the two sides of the bottom shell 311, the bottom shell 311, the left shell 312 and the right shell 313 jointly enclose to form the mounting groove 33 with the opening facing upward, wherein the bottom shell 311 and the left shell 312 and the right shell 313 are connected by screws.

[0047] Further, the side of the first surrounding seat 22 close to the lamp plate 1 is provided with a conductor ring, the lamp plate 1 is provided with a light emitting circuit for supplying power to the light emitting element 11, and the light emitting circuit is provided with a breakage part; when the first surrounding seat 22 abuts against the lamp plate 1, the conductor ring is connected with the breakage part to form a path between the light emitting circuit and the light emitting element 11, so that the current can be transmitted to the light emitting element 11 through the light emitting circuit and the conductor ring to supply the light emitting element 11 to work and emit light beams; when the first surrounding seat 22 is separated from the lamp plate 1, the conductor ring is separated from the breakage part to form a breakage between the light emitting circuit and the light emitting element 11, so that the current cannot be transmitted to the light emitting element 11 through the light emitting circuit, and the light emitting element 11 cannot be turned on to emit light beams.

[0048] Specifically, the lighting circuit is divided by a circuit breaker into a first circuit connected to the power supply and a second circuit connected to the light-emitting element. Whether the first circuit and the second circuit are conductive is determined by the coordination between the circuit breaker and the conductor ring. If the conductor ring is in contact with the circuit breaker, the first circuit and the second circuit are conductive. If the conductor ring is separated from the circuit breaker, the first circuit and the second circuit are disconnected. The circuit breaker is a groove provided on the lamp board. The groove can be directly provided on the lamp board or provided on a slot mounted on the lamp board. A first conductive contact and a second conductive contact are provided at the bottom of the groove, near the first circuit and near the second circuit, respectively. The first conductive contact is electrically connected to the first circuit, and the second conductive contact is electrically connected to the second circuit. The conductor ring is a conductive material that surrounds the lower edge of the first enclosure 22 and protrudes toward the lamp board 1. Its shape is designed to match the groove on the lamp board 1 to ensure close contact during assembly. During assembly, the first mounting bracket 22 is placed on the light board 1, and the conductor ring is aligned with and inserted into the groove. As the lens 2 is assembled, the conductor ring presses tightly against the first and second conductive contacts. When the conductor ring contacts both the first and second conductive contacts, the first and second circuits, previously separated by the disconnect, form a complete circuit path through the conductor ring and the first and second conductive contacts. At this point, current can flow from the power source through the first circuit, the first conductive contact, the conductor ring, the second conductive contact, and the second circuit, ultimately reaching the light-emitting element 11, causing it to emit light. When the first mounting bracket 22 is removed from the light board, the pressure between the conductor ring and the first and / or second conductive contacts is released, causing the conductor ring to separate, disconnecting the light-emitting circuit again. The light-emitting element 11 loses its current supply and ceases to emit light.

[0049] In this embodiment, when the first surrounding seat 22 is in close contact with the light board 1, the conductor ring is connected to the disconnection portion in the light-emitting circuit, forming a complete circuit path, allowing current to flow through the light-emitting circuit and be transmitted to the light-emitting element 11, thereby stimulating the light-emitting element 11 to emit light. Conversely, when the first surrounding seat 22 is separated from the light board 1, the conductor ring is disconnected from the disconnection portion, the circuit is broken, and the current cannot be transmitted to the light-emitting element 11, so the light-emitting element 11 is extinguished. In addition, the addition of the switch portion allows the user to directly control the on and off of the circuit by operating the switch portion, thereby controlling the working state of the light-emitting element 11. The cooperation between the conductor ring and the disconnection portion enables convenient control of the light-emitting element 11. When the light-emitting element 11 does not need to emit light, energy consumption is reduced by disconnecting the circuit, thereby improving energy utilization efficiency.

[0050] Based on this, the light source device is also provided with a self-test trigger control, such as a button, switch, knob, or virtual button on a display screen. When the self-test trigger control is triggered, the light source device controls each light-emitting element 11 to flash five times within one second for five seconds, thereby detecting whether the light-emitting element 11 is properly installed. The number of flashes per second and the duration of the self-test can be selected as needed and are not limited by this application.

[0051] Furthermore, the light board 1 is further provided with a first elastic limiting component and a second elastic limiting component, and the first elastic limiting component and the second elastic limiting component are symmetrically arranged on both sides of the light emitting element 11;

[0052] The first elastic limiting assembly includes a first fixed block 4 and a first slider 41. The first fixed block 4 is fixed to the lamp board 1. The first slider 41 is arranged on the side of the first fixed block 4 facing the light-emitting element 11. The first fixed block 4 and the first slider 41 are connected by a plurality of first springs 42. The first springs 42 always provide elastic force for the first slider 41 toward the light-emitting element 11. The side of the first slider 41 facing the light-emitting element 11 is provided with a first arc-shaped fitting surface 411. The curvature of the first arc-shaped fitting surface 411 corresponds to the outer diameter of the first surrounding seat 22.

[0053] The second elastic limiting assembly includes a second fixed block 5 and a second slider 51. The second fixed block 5 is fixed to the lamp board 1. The second slider 51 is arranged on the side of the second fixed block 5 facing the light-emitting element 11. The second fixed block 5 and the second slider 51 are connected by a plurality of second springs 52. The second springs 52 always provide the second slider 51 with an elastic force toward the light-emitting element 11. The second slider 51 is provided with a second arc-shaped fitting surface 511 on the side facing the light-emitting element 11. The curvature of the second arc-shaped fitting surface 511 corresponds to the outer diameter of the first surrounding seat 22; a clamping guide space is formed between the first arc-shaped fitting surface 411 and the second arc-shaped fitting surface 511, and the center of the clamping guide space coincides with the center of the light-emitting element 11.

[0054] In this embodiment, when the first seat 22 is placed on the light board 1, it first contacts the first arcuate fitting surface 411 and the second arcuate fitting surface 511 on the first slider 41 and the second slider 51. As the first seat 22 is further placed, the first slider 41 and the second slider 51 are subjected to pressure and move toward the first fixing block 4 and the second fixing block 5, respectively, compressing the first spring 42 and the second spring 52. When the first seat 22 is fully in place, the elastic force of the first spring 42 and the second spring 52 pushes the first slider 41 and the second slider 51 back, so that the first arcuate fitting surface 411 and the second arcuate fitting surface 511 are tightly fitted to the outer surface of the first seat 22, forming a stable clamp. When the light board 1 or the first seat 22 is subjected to vibration or impact, the elasticity of the first spring 42 and the second spring 52 can absorb energy, reducing potential damage to the light-emitting element 11.

[0055] Furthermore, the first elastic limiting assembly also includes a first rotating block 43 and a first abutting block 46, and the second elastic limiting assembly also includes a second rotating block 53 and a second abutting block 56. The end of the first rotating block 43 is rotatably connected to the end of the first slider 41, and the end of the second rotating block 53 is rotatably connected to the end of the second slider 51. The first rotating block 43 is provided with a third arc-shaped fitting surface 431 on the side facing the light-emitting element 11, and the curvature of the third arc-shaped fitting surface 431 corresponds to the outer diameter of the first surrounding seat 22, and a first blocking block 432 is further provided on the third arc-shaped fitting surface 431; the second rotating block 53 is provided with a fourth arc-shaped fitting surface 531 on the side facing the light-emitting element 11, and the curvature of the fourth arc-shaped fitting surface 531 corresponds to the outer diameter of the first surrounding seat 22, and a second blocking block 532 is further provided on the fourth arc-shaped fitting surface 531; a first guide groove 12 and a second guide groove are provided on the lamp board 1 When the first bracket 22 is in contact with the light board 1, the first slider 41 and the second slider 51 are squeezed away from each other by the lens 2, and the first rotating block 43 and the second rotating block 53 are respectively blocked by the first bracket 46 and the second bracket 56 and rotate toward the light board 11 to embrace each other; when the first bracket 22 is completely in contact with the light board 1, the first arcuate fitting surface 411, the second arcuate fitting surface 511, the third arcuate fitting surface 431, and the fourth arcuate fitting surface 531 are all in contact with the outside of the lens 2, and the first blocking block 432 and the second blocking block 532 are clamped on the lens 2 to limit the movement of the lens 2 away from the light board 1. It is understandable that the user can change the position of the first abutment block 46 in the first guide groove 12 and the position of the second abutment block 56 in the second guide groove 13 by himself, so as to make the first abutment block 46 and the second abutment block 56 abut against the first rotating block 43 and the second rotating block 53 respectively so as to facilitate the automatic engagement of the first rotating block 43 and the second rotating block 53 during the installation of the lens 2. Alternatively, the user can also make the first abutment block 46 and the second abutment block 56 respectively release the abutment relationship with the first rotating block 43 and the second rotating block 53 to facilitate the disassembly or position adjustment of the lens 2.

[0056] Optionally, a third spring 44 is connected between the first rotating block 43 and the first fixed block 4. Optionally, the third spring 44 continuously provides an elastic force for the first rotating block 43 toward the first fixed block 4, so that when the lens 2 needs to be released, the first abutting block 46 is adjusted to release the abutting force on the first rotating block 43. The first rotating block 43 can be automatically separated from the lens 2 by the tension of the third spring 44, thereby releasing the movement restriction of the lens 2 away from the light board 1. Optionally, a fourth spring 54 is connected between the second rotating block 53 and the second fixed block 5. Optionally, the fourth spring 54 continuously provides an elastic force for the second rotating block 53 toward the second fixed block 5. When the lens 2 needs to be released, the second abutting block 56 is adjusted to release the abutting force on the second rotating block 53. The second rotating block 53 can be automatically separated from the lens 2 by the tension of the fourth spring 54, thereby releasing the movement restriction of the lens 2 away from the light board 1.

[0057] In this embodiment, when the first surrounding seat 22 begins to approach the lamp board 1, it first contacts the first slider 41 and the second slider 51 and pushes them away from each other. As the lens 2 is further advanced, the first slider 41 and the second slider 51 will respectively drive the first rotating block 43 and the second rotating block 53 to rotate. Due to the obstruction of the first abutment block 46 and the second abutment block 56, the first rotating block 43 and the second rotating block 53 can only embrace toward the direction of the light-emitting element 11. When the first surrounding seat 22 is completely in contact with the lamp board 1, the first curved fitting surface 411, the second curved fitting surface 511, the third curved fitting surface 431 and the fourth curved fitting surface 531 are all tightly fitted to the outer surface of the lens 2. At the same time, the first clamping block 432 and the second clamping block 532 are respectively clamped into the corresponding positions of the lens 2 to limit the movement of the lens 2 away from the lamp board 1. The tight fit of multiple first curved fitting surfaces 411, the second curved fitting surface 511, the third curved fitting surface 431 and the fourth curved fitting surface 531 and the clamping action of the first clamping block 432 and the second clamping block 532 ensure that the lens 2 is stably fixed on the lamp board 1.

[0058] Furthermore, the first elastic limiting assembly also includes two first guide rods 45 disposed between the first fixed block 4 and the first slider 41. One end of the first guide rod 45 is fixed to the first slider 41, and the other end passes through the first fixed block 4 and is slidably connected to the first fixed block 4. The second elastic limiting assembly also includes two second guide rods 55 disposed between the second fixed block 5 and the second slider 51. One end of the second guide rod 55 is fixed to the second slider 51, and the other end passes through the second fixed block 5 and is slidably connected to the second fixed block 5. It can be understood that when the lens 2 begins to be installed and approaches the light board 1, it first contacts the first slider 41 and the second slider 51, and pushes them to move away from each other along the first guide rod 45 and the second guide rod 55, respectively. Due to the restraining effect of the first guide rod 45 and the second guide rod 55, the first slider 41 and the second slider 51 can move smoothly along the predetermined path without deflection or rotation. The first guide rod 45 and the second guide rod 55 provide precise movement paths and positioning for the movement of the first slider 41 and the second slider 51 respectively, so that the lens 2 can be more accurately installed in the predetermined position, thereby improving the installation accuracy and reliability.
