[0025] Please see attached Figures 1 to 8 The embodiment of the present invention provides a light source device, comprising: a lamp board 1, on which a light-emitting element 11 is arranged; a lens 2, wherein the light-incoming side of the lens 2 is covered 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 sides of the axial direction of the lens portion 21, the first surrounding seat 22 is located on the light-incoming side of the lens 2, and the first surrounding seat 22, the lens portion 21, and the lamp board 1 are combined to 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, and the second surrounding seat 23 and the lens portion 21 are combined to form a light-emitting groove 231, the side of the lens portion 21 facing the light-incoming groove 221 is a plane, and the side of the lens portion 21 facing the light-emitting groove 231 is a beaded surface. It should be explained that the light emitting element 11 and the lens 2 in this embodiment are in an adaptive relationship, and the size of the lens 2 is designed according to the size of the light emitting element 11 to improve the luminous efficiency of the light emitting element 11, so as to achieve the best lighting effect and service life. It can be understood that the side of the lens portion 21 facing the light inlet groove 221 is a plane, which is convenient for receiving the light emitted by the light emitting element 11, and the side of the lens portion 21 facing the light outlet groove 231 is a beaded surface, 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 surrounding seat 22 and the second surrounding seat 23 respectively enclose the light inlet groove 221 and the light outlet groove 231 with the lens portion 21, which play the role of fixing and protecting the light emitting element 11, and also ensure the effective transmission of light in the lens 2. In actual applications, 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 to completely cover 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 to enter the interior of the lens 2, and then is refracted and focused by the bead-shaped light-emitting side, and finally is 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 size of the device.

[0026] Specifically, the light emitting element 11 is a 7070 lamp bead.

[0027] Furthermore, it also includes a strobe controller, which is electrically connected to the light board 1 and is used to control the light-emitting element 11 to flash. When the strobe controller is working, the light-emitting element 11 is controlled to perform a flashing action of a flashing time at intervals of a waiting time, the waiting time is 15ms, and the flashing 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 flashing 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, and 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.

[0028] 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 alternately perform low-power waiting time and high-power flashing time in each cycle, during the waiting time (15ms), the light emitting element 11 works at its rated power, and 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 visual persistence 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 is still maintained at a relatively low level. In addition, the light emitting element 11 works at the 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.

[0029] Furthermore, it also includes a mounting box 3, in which the light 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 outlet groove 231. Through the design of the mounting box 3, this embodiment realizes the effective integration and packaging of components such as the light 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.

[0030] Furthermore, the installation box 3 includes a base 31 and a cover plate 32. The base 31 is provided with a mounting groove 33. The lamp board 1 is provided in the mounting groove 33. The light emitting element 11 and the lens 2 are provided on the side of the lamp board 1 facing the notch of the mounting groove 33. The cover plate 32 is connected to the notch of the mounting groove 33. The air avoidance hole 321 is provided on the cover plate 32. The air avoidance hole 321 is provided with an annular alignment groove outwardly on the side facing the lens 2. The first surrounding seat 22 abuts against the lamp board 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, which are connected together by screws or snaps to form a complete installation box 3 structure, wherein the mounting groove 33 is used to accommodate and fix the lamp board 1, and the annular alignment groove is used to accurately align and fix the lens 2. The first surrounding seat 22 and the second surrounding seat 23 abut against the lamp board 1 and the annular alignment groove, respectively, which further enhances the connection stability and assembly accuracy between the components.

[0031] 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, and the bottom shell 311, the left shell 312 and the right shell 313 are jointly enclosed to form a mounting groove 33 with an opening facing upward, wherein the bottom shell 311 and the left shell 312 and the right shell 313 are connected by screws.

[0032] Furthermore, a conductor ring is provided on one side of the first enclosure 22 close to the lamp board 1, and a light-emitting circuit for powering the light-emitting element 11 is provided on the lamp board 1, and a disconnecting portion is provided in the light-emitting circuit; when the first enclosure 22 abuts against the lamp board 1, the conductor ring is connected to the disconnecting portion to form a passage between the light-emitting circuit and the light-emitting element 11, and 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 board 1, the conductor ring is separated from the disconnecting portion to form a disconnecting circuit between the light-emitting circuit and the light-emitting element 11, and 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.

[0033] Specifically, the light-emitting circuit is divided into a first circuit connected to a power source and a second circuit connected to a light-emitting element by a circuit breaker. Whether the first circuit and the second circuit are connected is determined by the matching relationship between the circuit breaker and the conductor ring. If the conductor ring is connected to the circuit breaker, the first circuit and the second circuit are connected. 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 arranged on the lamp board. The groove can be directly opened on the lamp board or opened on a groove body installed on the lamp board. A first conductive contact and a second conductive contact are respectively arranged 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 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 the assembly process, the first enclosure 22 is placed on the lamp board 1, and the conductor ring is aligned with the groove and inserted into the groove. As the lens 2 is assembled, the conductor ring is tightly pressed on the first conductive contact and the second conductive contact. When the conductor ring is in contact with both the first conductive contact and the second conductive contact, the first circuit and the second circuit originally separated by the circuit breaker form a complete circuit path through the conductor ring and the first conductive contact and the second conductive contact. At this time, the current can pass from the power supply through the first circuit, the first conductive contact, the conductor ring, the second conductive contact, and the second circuit, and finally reach the light-emitting element 11, causing it to emit light. When the first enclosure 22 is removed from the lamp board, the pressure between the conductor ring and the first conductive contact and / or the second conductive contact is released and separated, which will disconnect the light-emitting circuit again, and the light-emitting element 11 loses the current supply and stops emitting light.

[0034] In this embodiment, when the first enclosure 22 is in close contact with the lamp board 1, the conductor ring is connected to the disconnection part in the light-emitting circuit to form a complete circuit path, so that the current can 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. On the contrary, when the first enclosure 22 is separated from the lamp board 1, the conductor ring is disconnected from the disconnection part, the circuit is broken, the current cannot be transmitted to the light-emitting element 11, and the light-emitting element 11 is therefore extinguished. In addition, the addition of the switch part allows the user to directly control the on and off of the circuit by operating the switch part, thereby realizing the control of the working state of the light-emitting element 11. Through the cooperation of the conductor ring and the disconnection part, convenient control of the light-emitting element 11 is realized. When the light-emitting element 11 does not need to emit light, the energy consumption is reduced by disconnecting the circuit, thereby improving the energy utilization efficiency.

[0035] Based on this, the light source device is also provided with a self-check trigger control, such as a button, a switch, a knob, a virtual button in a display screen, etc. After the self-check trigger control is triggered, the light source device will control each light emitting element 11 to flash 5 times within 1S for 5S, thereby detecting whether the light emitting element 11 is installed in place. Among them, the number of flashes per second and the duration of the self-check can be selected as needed, and this application does not impose any restrictions.

[0036] Furthermore, the light board 1 is also 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; 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 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 arcuate fitting surface 411. The curvature of the first arcuate fitting surface 411 corresponds to the outer diameter of the first surrounding seat 22. 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 elastic force in the direction of the light-emitting element 11, and a second arc-shaped fitting surface 511 is arranged on the side of the second slider 51 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.

[0037] In this embodiment, when the first surrounding seat 22 is placed on the light board 1, it first contacts the first arc-shaped fitting surface 411 and the second arc-shaped fitting surface 511 on the first slider 41 and the second slider 51. As the first surrounding 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 surrounding 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 fitting surface 411 and the second arc-shaped fitting surface 511 are closely fitted to the outer surface of the first surrounding seat 22, forming a stable clamping. When the light board 1 or the first surrounding 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.

[0038] 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 sliding block 41, and the end of the second rotating block 53 is rotatably connected to the end of the second sliding block 51.

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 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.

[0039] Optionally, a third spring 44 is connected between the first rotating block 43 and the first fixed block 4. Optionally, the third spring 44 always provides elastic force for the first rotating block 43 in the direction of the first fixed block 4, so that when the lens 2 needs to be unlocked, after the abutment force on the first rotating block 43 is released by adjusting the position of the first abutment block 46, the first rotating block 43 can automatically detach from the lens 2 by the pulling force of the third spring 44, thereby releasing the movement limit 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 always provides elastic force for the second rotating block 53 in the direction of the second fixed block 5, so that when the lens 2 needs to be unlocked, after the abutment force on the second rotating block 53 is released by adjusting the position of the second abutment block 56, the second rotating block 53 can automatically detach from the lens 2 by the pulling force of the fourth spring 54, thereby releasing the movement limit of the lens 2 away from the light board 1.

[0040] 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 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 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 arcuate fitting surfaces 411, the second arcuate fitting surface 511, the third arcuate fitting surface 431 and the fourth arcuate 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.

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 offset 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 at a predetermined position, thereby improving the installation accuracy and reliability.

[0042] The light source device of this embodiment makes the lens portion flat on the light incident side facing the light-emitting element and beaded on the light emitting side, and cooperates with the groove formed by the first surrounding seat and the second surrounding seat to more effectively focus and enhance the light, so that a compact LED light source can also emit high-brightness light, thereby meeting the visual industry's demand for high brightness.
