[0002] LED light sources are now widely used in the visual industry, but some compact LED light sources suffer from insufficient brightness. Brightness is primarily increased by adding more LEDs or increasing their power, but these methods inevitably lead to an increase in the overall size of the device, thus deviating from the compact design of some LED light sources. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a light source device to solve the technical problem that existing LED light sources increase brightness by increasing the number of LEDs or increasing LED power, resulting in an increase in the overall size of the device, thus deviating from the design of some LED light sources to be compact.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention provides a light source device, comprising:

[0006] A light panel, wherein a light-emitting element is provided on the light panel;

[0007] A lens, wherein the light-inlet side of the lens is disposed over the light-emitting element, and the light emitted by the light-emitting element passes through the lens and exits from the light-outlet side of the lens;

[0008] The lens includes a lens portion and a first enclosure and a second enclosure extending on both axial sides of the lens portion. The first enclosure is located on the light-inlet side of the lens and forms a light-inlet groove with the lens portion and the lamp plate for mounting the light-emitting element. The second enclosure is located on the light-outlet side of the lens and forms a light-outlet groove with the lens portion. The side of the lens portion facing the light-inlet groove is flat, and the side of the lens portion facing the light-outlet groove is beaded.

[0012] Furthermore, it also includes a mounting box, in which the lamp board, light-emitting element, and lens are all housed, and the mounting box has a clearance hole corresponding to the light-emitting slot.

[0013] Furthermore, the mounting box includes a base and a cover plate.

[0015] Furthermore, a conductor ring is provided on the side of the first enclosure near the lamp panel, and a light-emitting circuit for supplying power to the light-emitting element is provided on the lamp panel, wherein the light-emitting circuit has a circuit breaker; when the first enclosure abuts against the lamp panel, the conductor ring is connected to the circuit breaker, thereby forming a path between the light-emitting circuit and the light-emitting element; when the first enclosure is separated from the lamp panel, the conductor ring is separated from the circuit breaker, thereby forming a circuit breaker between the light-emitting circuit and the light-emitting element.

[0016] Furthermore, the lamp panel is also provided with a first elastic limiting component and a second elastic limiting component, which are symmetrically arranged on both sides of the light-emitting element.

[0017] The first elastic limiting component includes a first fixing block and a first slider. The first fixing block is fixed to the lamp plate, and the first slider is disposed on the side of the first fixing block facing the light-emitting element. The first fixing block and the first slider are connected by a plurality of first springs. The first springs always provide elastic force to the first slider in the direction of the light-emitting element. The side of the first slider facing the light-emitting element is provided with a first arc-shaped contact surface, and the arc of the first arc-shaped contact surface corresponds to the outer diameter of the first enclosure.

[0018] The second elastic limiting component includes a second fixing block and a second slider. The second fixing block is fixed to the lamp plate, and the second slider is disposed on the side of the second fixing block facing the light-emitting element. The second fixing block and the second slider are connected by a plurality of second springs. The second springs always provide elastic force to the second slider in the direction of the light-emitting element. The side of the second slider facing the light-emitting element is provided with a second arc-shaped contact surface. The arc of the second arc-shaped contact surface corresponds to the outer diameter of the first enclosure. A clamping and guiding space is formed between the first arc-shaped contact surface and the second arc-shaped contact surface.

[0019] Furthermore, the first elastic limiting component further includes a first rotating block and a first abutting block, and the second elastic limiting component further includes a second rotating block and a second abutting block. The end of the first rotating block is rotatably connected to the end of the first slider, and the end of the second rotating block is rotatably connected to the end of the second slider. The first rotating block has a third arc-shaped contact surface on the side facing the light-emitting element, and the curvature of the third arc-shaped contact surface corresponds to the outer diameter of the first enclosure. A first locking block is also provided on the third arc-shaped contact surface. The second rotating block has a fourth arc-shaped contact surface on the side facing the light-emitting element, and the curvature of the fourth arc-shaped contact surface corresponds to the outer diameter of the first enclosure. A second locking block is also provided on the fourth arc-shaped contact surface. A first guide groove and a second guide groove are provided on the lamp plate. The abutment block is detachably fixed to the first guide groove and abuts against the side of the first rotating block away from the light-emitting element. The second abutment block is detachably fixed to the second guide groove and abuts against the side of the second rotating block away from the light-emitting element. When the first enclosure approaches the lamp plate, the first slider and the second slider are squeezed away from each other by the lens. The first rotating block and the second rotating block are respectively obstructed by the first abutment block and the second abutment block and rotate towards the light-emitting element to embrace each other. When the first enclosure is completely abutted against the lamp plate, the first arc-shaped contact surface, the second arc-shaped contact surface, the third arc-shaped contact surface, and the fourth arc-shaped contact surface are all in contact with the outside of the lens. The first locking block and the second locking block are locked onto the lens to limit the movement of the lens away from the lamp plate.

[0020] Furthermore, the first elastic limiting component also includes two first guide rods disposed between the first fixed block and the first slider, one end of the first guide rod being fixed to the first slider, and the other end passing through the first fixed block and slidably connected to the first fixed block; the second elastic limiting component also includes two second guide rods disposed between the second fixed block and the second slider, one end of the second guide rod being fixed to the second slider, and the other end passing through the second fixed block and slidably connected to the second fixed block.

[0021] The light source device of the present invention, by making the lens portion planar on the light-incident side facing the light-emitting element and bead-shaped on the light-emitting side, and in conjunction with the groove formed by the first and second enclosures, can more effectively focus and enhance light, so that even a small LED light source can emit high-brightness light, meeting the high-brightness requirements of the visual industry.

[0040] Please see the appendix Figures 1 to 8This invention provides a light source device, comprising: a lamp plate 1, on which a light-emitting element 11 is disposed; a lens 2, the light-inlet side of the lens 2 covering the light-emitting element 11, the light emitted by the light-emitting element 11 passing through the lens 2 and exiting from the light-emitting side of the lens 2; wherein, the lens 2 includes a lens portion 21, and a first enclosure 22 and a second enclosure 23 extending on both axial sides of the lens portion 21 respectively, the first enclosure 22 being located on the light-inlet side of the lens 2, the first enclosure 22, the lens portion 21, and the lamp plate 1 enclosing to form a light-inlet groove 221 for accommodating the light-emitting element 11; the second enclosure 23 being located on the light-emitting side of the lens 2, the second enclosure 23, and the lens portion 21 enclosing to form a light-emission groove 231, the side of the lens portion 21 facing the light-inlet groove 221 being planar, and the side of the lens portion 21 facing the light-emission groove 231 being beaded. It should be explained that in this embodiment, the light-emitting element 11 and the lens 2 are compatible. The size of the lens 2 is designed to match the size of the light-emitting element 11 to improve its luminous efficiency and achieve optimal lighting effect and lifespan. It can be understood that the side of the lens portion 21 facing the light-entry groove 221 is flat, facilitating the reception of light emitted by the light-emitting element 11, while the side of the lens portion 21 facing the light-exit groove 231 is beaded, which can change the direction of light propagation, making the light more concentrated and directional, thereby improving luminous efficiency. Furthermore, the first enclosure 22 and the second enclosure 23, together with the lens portion 21, form the light-entry groove 221 and the light-exit groove 231, respectively, serving to fix and protect the light-emitting element 11, while also ensuring effective light transmission within the lens 2. In practical applications, the light-emitting element 11 of this embodiment is precisely mounted on the lamp plate 1. The first enclosure 22 of the lens 2 and the lamp plate 1 form an entry light groove 221, completely covering the light-emitting element 11. When the light-emitting element 11 emits light, the light first passes through the planar side of the lens part 21 and enters the interior of the lens 2. Then, it 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. This allows the luminous efficiency to be improved without increasing the number of LEDs or increasing the power of a single LED, thus avoiding an increase in the size of the device.

[0041] Specifically, the light-emitting element 11 is a 7070 LED.

[0042] Furthermore, a flicker controller is included, electrically connected to the lamp board 1, for controlling the strobe effect of the light-emitting element 11. When the flicker controller is working, it controls the light-emitting element 11 to perform a strobe action for one strobe duration at intervals of 15ms and 1ms. When the light-emitting element 11 is in the waiting period, it operates at its rated power; when the light-emitting element 11 is in the strobe duration, its actual power is four times its rated power. It can be understood that this embodiment uses a flicker-based brightness enhancement method to instantaneously increase the power of the light source device at its normal rated power. During this process, the human eye cannot perceive the instant the light source device turns on and off, resulting in a visually continuous illuminated state, thus achieving a high-brightness state. Optionally, the flicker controller is a PM-S-48W200-4T flicker controller.

[0043] In this embodiment, the strobe controller is electrically connected to the lamp board 1 and can periodically adjust the power of the light-emitting element 11. By controlling the light-emitting element 11 to alternate between low-power waiting time and high-power flashing time in each cycle, during the waiting time (15ms), the light-emitting element 11 operates at its rated power. 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 in the human eye, this rapid power change is visually smoothed into continuous high-brightness illumination. It should be explained that this solution achieves a visually continuous high-brightness effect through strobe-based brightness enhancement, meeting the needs of specific application scenarios. Although the power of the light-emitting element 11 is high during the flashing time, the overall energy consumption remains relatively low due to its extremely short duration. Furthermore, the light-emitting element 11 operates at its rated power most of the time, reducing overheating and losses caused by prolonged high-power operation, thereby extending the service life of the light-emitting element 11.

[0044] Furthermore, the device also includes a mounting box 3, within which the lamp board 1, the light-emitting element 11, and the lens 2 are all housed. The mounting box 3 has clearance holes 321 corresponding to the light-emitting slot 231. This embodiment, through the design of the mounting box 3, achieves effective integration and encapsulation of components such as the lamp board 1, the light-emitting element 11, and the lens 2, improving the integration and compactness of the light source device. Simultaneously, the mounting box 3 provides excellent protection for the light source device, preventing interference and damage from external environments such as dust and moisture, thus extending the lifespan of the light source device. Preferably, the mounting box 3 is equipped with a heat dissipation structure or material, such as a heat sink, a cooling fan, or thermally conductive adhesive, to improve the heat dissipation performance of the light source device and ensure that it does not overheat during high-power operation.

[0045] Furthermore, the mounting box 3 includes a base 31 and a cover plate 32. The base 31 has a mounting groove 33, within which the lamp plate 1 is positioned. The light-emitting element 11 and the lens 2 are positioned on the side of the lamp plate 1 facing the opening of the mounting groove 33. The cover plate 32 is connected to the opening of the mounting groove 33, and a clearance hole 321 is provided on the cover plate 32. The clearance hole 321 has an outwardly extending an annular alignment groove on the side facing the lens 2. A first retaining seat 22 abuts against the lamp plate 1, and a second retaining seat 23 abuts against the annular alignment groove. It can be understood that the base 31 and the cover plate 32, as two independent modules, are connected together by screws or snap-fits to form a complete mounting box 3 structure. The mounting groove 33 is used to accommodate and fix the lamp plate 1, while the annular alignment groove is used for precise alignment and fixing of the lens 2. The first retaining seat 22 and the second retaining seat 23 abut against the lamp plate 1 and the annular alignment groove, respectively, further enhancing the connection stability and assembly accuracy between components.

[0046] Optionally, the base 31 includes a U-shaped bottom shell 311, and a left shell 312 and a right shell 313 connected to the openings on both sides of the bottom shell 311. The bottom shell 311, the left shell 312 and the right shell 313 together form an upward-facing mounting groove 33, wherein the bottom shell 311 and the left shell 312 and the right shell 313 are connected by screws.

[0047] Furthermore, a conductor ring is provided on the side of the first enclosure 22 near the lamp plate 1. The lamp plate 1 is provided with a light-emitting circuit for supplying power to the light-emitting element 11. The light-emitting circuit has a break-circuit part. When the first enclosure 22 abuts against the lamp plate 1, the conductor ring is connected to the break-circuit part, so that a path is formed between the light-emitting circuit and the light-emitting element 11. Current can be transmitted to the light-emitting element 11 through the light-emitting circuit and the conductor ring, so that the light-emitting element 11 can work and emit a light beam. When the first enclosure 22 is separated from the lamp plate 1, the conductor ring is separated from the break-circuit part, so that a break-circuit is formed between the light-emitting circuit and the light-emitting element 11. Current cannot be transmitted to the light-emitting element 11 through the light-emitting circuit, and the light-emitting element 11 cannot light up to emit a light beam.

[0048] Specifically, the light-emitting circuit is divided into a first circuit connected to the power supply and a second circuit connected to the light-emitting element by a circuit breaker. Whether the first and second circuits are connected is determined by the fit between the circuit breaker and the conductor ring. If the conductor ring is connected to the circuit breaker, the first and second circuits are connected; if the conductor ring is disconnected from the circuit breaker, the first and second circuits are disconnected. The circuit breaker is a groove on the lamp plate. This groove can be directly formed on the lamp plate or formed in a slot mounted on the lamp plate. A first conductive contact and a second conductive contact are respectively provided at the bottom of the groove near the first circuit and near the second circuit. 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 base 22 and protrudes towards the lamp plate 1. Its shape is designed to match the groove on the lamp plate 1 to ensure tight contact during assembly. During assembly, the first retainer 22 is placed on the lamp plate 1, and the conductor ring is aligned with and inserted into the groove. As the lens 2 is assembled, the conductor ring is pressed tightly against the first and second conductive contacts. When the conductor ring is in contact with both the first and second conductive contacts, the first and second circuits, which were originally separated by a circuit breaker, form a complete circuit path through the conductor ring, the first conductive contact, and the second conductive contact. At this time, 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 and causing it to emit light. When the first retainer 22 is removed from the lamp plate, the pressure between the conductor ring and the first and / or second conductive contacts is released, causing the light-emitting circuit to disconnect again. The light-emitting element 11 loses its current supply and stops emitting light.

[0049] In this embodiment, when the first enclosure 22 is in close contact with the lamp board 1, the conductor ring connects with the break in the light-emitting circuit, forming a complete circuit path. This allows current to flow through the light-emitting circuit and be transmitted to the light-emitting element 11, thereby exciting the light-emitting element 11 to emit light. Conversely, when the first enclosure 22 is separated from the lamp board 1, the conductor ring disconnects from the break, the circuit is broken, and current cannot be transmitted to the light-emitting element 11, thus extinguishing the light-emitting element 11. Furthermore, the addition of a switch allows the user to directly control the circuit's on / off state by operating the switch, thereby controlling the operating state of the light-emitting element 11. Through the cooperation of the conductor ring and the break, convenient control of the light-emitting element 11 is achieved. When the light-emitting element 11 does not need to emit light, the circuit is disconnected to reduce energy consumption and improve energy efficiency.

[0050] Based on this, the light source device is also equipped with a self-test trigger control, such as a button, switch, knob, or virtual button on the display screen. After the self-test trigger control is triggered, the light source device will control each light-emitting element 11 to flash 5 times within 1 second for 5 seconds, thereby detecting whether the light-emitting element 11 is installed in place. The number of flashes per second and the self-test duration can be selected as needed, and this application does not impose any restrictions.

[0051] Furthermore, the lamp panel 1 is also provided with a first elastic limiting component and a second elastic limiting component, which are symmetrically arranged on both sides of the light-emitting element 11.

[0052] The first elastic limiting component includes a first fixing block 4 and a first slider 41. The first fixing block 4 is fixed to the lamp plate 1. The first slider 41 is disposed on the side of the first fixing block 4 facing the light-emitting element 11. The first fixing block 4 and the first slider 41 are connected by a plurality of first springs 42. The first springs 42 always provide elastic force to the first slider 41 in the direction of 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 contact surface 411. The arc of the first arc-shaped contact surface 411 corresponds to the outer diameter of the first enclosure 22.

[0053] The second elastic limiting component includes a second fixing block 5 and a second slider 51. The second fixing block 5 is fixed to the lamp plate 1, and the second slider 51 is disposed on the side of the second fixing block 5 facing the light-emitting element 11. The second fixing block 5 and the second slider 51 are connected by a number of second springs 52. The second springs 52 always provide elastic force to the second slider 51 in the direction of the light-emitting element 11. The side of the second slider 51 facing the light-emitting element 11 is provided with a second arc-shaped contact surface 511. The arc of the second arc-shaped contact surface 511 corresponds to the outer diameter of the first enclosure 22. A clamping and guiding space is formed between the first arc-shaped contact surface 411 and the second arc-shaped contact surface 511. The center of the clamping and guiding space coincides with the center of the light-emitting element 11.

[0054] In this embodiment, when the first retaining seat 22 is placed on the lamp plate 1, it first contacts the first arc-shaped contact surface 411 and the second arc-shaped contact surface 511 on the first slider 41 and the second slider 51. As the first retaining seat 22 is further placed, the first slider 41 and the second slider 51 are subjected to pressure and move towards 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 retaining 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 arc-shaped contact surface 411 and the second arc-shaped contact surface 511 are tightly attached to the outer surface of the first retaining seat 22, forming a stable clamping. When the lamp plate 1 or the first retaining seat 22 is subjected to vibration or impact, the elasticity of the first spring 42 and the second spring 52 can absorb energy and reduce potential damage to the light-emitting element 11.

[0055] Furthermore, the first elastic limiting component also includes a first rotating block 43 and a first abutting block 46, and the second elastic limiting component 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 has a third arc-shaped contact surface 431 on the side facing the light-emitting element 11, and the curvature of the third arc-shaped contact surface 431 corresponds to the outer diameter of the first enclosure 22. A first locking block 432 is also provided on the third arc-shaped contact surface 431. The second rotating block 53 has a fourth arc-shaped contact surface 531 on the side facing the light-emitting element 11, and the curvature of the fourth arc-shaped contact surface 531 corresponds to the outer diameter of the first enclosure 22. A second locking block 532 is also provided on the fourth arc-shaped contact surface 531. A first guide groove 12 and a second guide groove 12 are provided on the lamp plate 1. The groove 13, the first abutting block 46 is detachably fixed to the first guide groove 12 and abuts against the side of the first rotating block 43 away from the light-emitting element 11, the second abutting block 56 is detachably fixed to the second guide groove 13 and abuts against the side of the second rotating block 53 away from the light-emitting element 11; when the first enclosure 22 approaches the lamp plate 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 obstructed by the first abutting block 46 and the second abutting block 56 and rotate towards the light-emitting element 11 to embrace each other; when the first enclosure 22 completely abuts against the lamp plate 1, the first arc-shaped contact surface 411, the second arc-shaped contact surface 511, the third arc-shaped contact surface 431 and the fourth arc-shaped contact surface 531 are all in contact with the outside of the lens 2, and the first locking block 432 and the second locking block 532 are locked onto the lens 2 to limit the movement of the lens 2 away from the lamp plate 1. Understandably, the user can change the position of the first abutting block 46 in the first guide groove 12 and the position of the second abutting block 56 in the second guide groove 13, so that the first abutting block 46 and the second abutting block 56 abut against the first rotating block 43 and the second rotating block 53 respectively, so that the first rotating block 43 and the second rotating block 53 can automatically engage during the installation of the lens 2. Alternatively, the user can also release the first abutting block 46 and the second abutting block 56 from the first rotating block 43 and the second rotating block 53 respectively, so as to facilitate the disassembly or position adjustment of the lens 2.

[0056] Optionally, a third spring 44 connects the first rotating block 43 and the first fixed block 4. Optionally, the third spring 44 always provides a spring force to the first rotating block 43 toward the first fixed block 4, so that when it is necessary to release the locking of the lens 2, after adjusting the position of the first abutment block 46 to release the abutment force on the first rotating block 43, the first rotating block 43 can automatically disengage from the lens 2 by the tension of the third spring 44, thereby releasing the movement restriction of the lens 2 away from the lamp panel 1. Optionally, a fourth spring 54 connects the second rotating block 53 and the second fixed block 5. Optionally, the fourth spring 54 always provides a spring force to the second rotating block 53 toward the second fixed block 5, so that when it is necessary to release the locking of the lens 2, after adjusting the position of the second abutment block 56 to release the abutment force on the second rotating block 53, the second rotating block 53 can automatically disengage from the lens 2 by the tension of the fourth spring 54, thereby releasing the movement restriction of the lens 2 away from the lamp panel 1.

[0057] In this embodiment, when the first enclosure 22 begins to approach the lamp panel 1, it first contacts the first slider 41 and the second slider 51 and pushes them away from each other. As the lens 2 advances further, 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 abutting block 46 and the second abutting block 56, the first rotating block 43 and the second rotating block 53 can only hug each other in the direction of the light-emitting element 11. When the first mounting base 22 is fully abutted against the lamp plate 1, the first arc-shaped contact surface 411, the second arc-shaped contact surface 511, the third arc-shaped contact surface 431, and the fourth arc-shaped contact surface 531 are all tightly attached to the outer surface of the lens 2. At the same time, the first locking block 432 and the second locking block 532 are respectively locked into the corresponding positions of the lens 2, thereby limiting the movement of the lens 2 away from the lamp plate 1. Through the tight contact of the multiple first arc-shaped contact surfaces 411, the second arc-shaped contact surface 511, the third arc-shaped contact surface 431, and the fourth arc-shaped contact surface 531, as well as the locking action of the first locking block 432 and the second locking block 532, the lens 2 is stably fixed on the lamp plate 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 is installed and approaches the lamp panel 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 constraint 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 deviation or rotation. The first guide rod 45 and the second guide rod 55 provide precise movement paths and positioning for the first slider 41 and the second slider 51, respectively, enabling the lens 2 to be installed more accurately in the predetermined position, thus improving the installation accuracy and reliability.
