Description

Technical Field

[0001] This invention relates to the field of lighting device components, specifically to a beam splitter structure for an LED lamp concentrator. Background Technology

[0002] The LED light concentrator beam splitter structure is a core optical component combination in LED lighting systems used for "light convergence + light path distribution / optimization". The core consists of a beam splitter, a concentrator and a matching installation and positioning structure, which ultimately achieves the functions of low beam glare reduction, high beam enhancement or light beam splitting, adapting to the needs of different lighting scenarios.

[0003] As the core optical component of LED light concentrators, beam splitters are mostly made of optical-grade materials (high-temperature PC, ultra-thin borosilicate glass) and may have optical coatings (multi-layer dielectric films, anti-reflective coatings) or integrated light-shielding structures (such as glare point light-shielding arrays) on their surface. They are responsible for the transmission, reflection and distribution of light (such as near beam transmission and far beam reflection superposition) or the elimination of glare.

[0004] When LED light passes through a beam splitter, some of it is absorbed by the material itself (such as high-temperature PC or optical glass) (the amount of absorption is positively correlated with the propagation distance). To achieve energy-saving lighting, the thickness of the beam splitter is often reduced. When the beam splitter is thinner, the propagation path of the light within the beam splitter is shortened, and the material absorption loss is reduced (at the same LED power). More light can be converted into effective lighting light. Conversely, to achieve the same lighting brightness, the LED driving power can be reduced (e.g., from 30W to 27W), achieving an energy-saving effect. However, when the thickness of the beam splitter is reduced, its bending and creep resistance decreases. Since the beam splitter is used at a high temperature (e.g., 80-120℃ when LEDs are working), the activity of material molecules increases at high temperatures, making it prone to warping due to its own gravity and thermal stress, leading to light path deviation. Therefore, we propose a beam splitter structure for LED lamp concentrators. Summary of the Invention

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments 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.

[0033] Example 1

[0034] Please see Figures 1-11 The diagram shows a beam splitter structure for an LED lamp concentrator, including a beam splitter body 104 disposed inside the LED lamp concentrator. The LED lamp concentrator includes a housing 101, inside which are arranged an optical unit 102 and a focusing unit 103. The beam splitter body 104 is disposed inside the housing 101.

[0035] It should be noted that after installation, the beam splitter body 104, together with the optical unit 102 and the focusing unit 103, performs beam splitting. During the beam splitting process, because the beam splitter body 104 is relatively thin, the propagation path of light within the beam splitter body 104 is shortened, and the material absorption loss is reduced (under the same LED power). More light can be converted into effective illumination light, achieving the effect of energy saving. The working principle of the relatively thin beam splitter body 104 achieving the effect of energy saving during use is a conventional technology in this application and will not be elaborated on here.

[0036] Furthermore, the component composition, control method, and operating principle of the beam splitter body 104, optical unit 102, and focusing unit 103 are conventional technical means in this application and will not be described in detail here.

[0037] Also includes:

[0038] The mounting component is located inside the housing 101 to assist in the installation and connection of the beam splitter body 104. The mounting component is provided with a positioning component for positioning the beam splitter body 104.

[0039] The support component is set on the mounting component to provide corresponding support to the upper and lower sides of the beam splitter body 104 after the beam splitter body 104 is installed, so as to prevent the beam splitter body 104 from deforming at high temperature.

[0040] And, an adjustment component provided on the mounting component for adjusting the support state of the support component;

[0041] It should be noted that when using the LED light concentrator, the installation components, positioning components, support components, and adjustment components work together to support the corresponding positions on the upper and lower sides of the beam splitter in different ways according to the usage status of the beam splitter. This reduces the probability of warping of the beam splitter body 104 under high temperature and facilitates the stable use of the beam splitter.

[0042] Preferably, the mounting assembly includes two sets of mounting side plates 201 symmetrically fixed inside the housing 101. The two sets of mounting side plates 201 have slots 202 on opposite sides for pushing the beam splitter body 104 into the mounting. The positioning assembly includes two sets of positioning holes 301 symmetrically arranged on the beam splitter body 104. A sliding hole 302 is provided through the mounting side plate 201. A positioning rod 303 for positioning with the positioning hole 301 is slidably connected to the sliding hole 302. A baffle 304 is fixed to the upper end of the positioning rod 303. A first spring 305 is sleeved on the outer side of the positioning rod 303. The two ends of the first spring 305 are respectively connected to the baffle 304 and the mounting side plate 201.

[0043] It should be noted here that during installation, the positioning rod 303 is first pulled upward by the baffle 304 to ensure that the positioning rod 303 does not obstruct the insertion and installation of the beam splitter body 104. During the upward pulling of the positioning rod 303, the first spring 305 deforms under stress, generating elastic force. After the positioning rod 303 is pulled upward, the beam splitter body 104 is pushed between the slots 202 of the two sets of mounting side plates 201 for installation. During the pushing of the beam splitter body 104, the beam splitter body 104... The positioning hole 301 on the 04 communicates with the sliding hole 302 on the mounting side plate 201. After the beam splitter body 104 is pushed in, the upward pull on the positioning rod 303 is released. The positioning rod 303 is reset under the elastic force of the first spring 305. During the reset process, one end of the positioning rod 303 passes through the positioning hole 301 of the beam splitter body 104. Through the interaction between the positioning rod 303 and the positioning hole 301, the beam splitter body 104 after being pushed in and installed is positioned, which facilitates the accurate installation and use of the beam splitter body 104.

[0044] Preferably, two sets of support components are symmetrically arranged on the mounting side plate 201. The mounting side plate 201 is provided with a connecting component for connecting the support components and a driving component for driving the support components. The support components include two sets of strip plates 401, which are symmetrically arranged on the upper and lower sides of the mounting side plate 201. The opposite side of the two sets of strip plates 401 is connected to a support rod 402 through an elastic component. One end of the support rod 402 is provided with a rolling component for abutting against the surface of the beam splitter body 104 after installation.

[0045] It should be noted that during the installation of the beam splitter body 104, the push-in end of the beam splitter body 104 abuts against the ball bearing 502 at the front end of the support rod 402 on the support assembly. During this abutment, the ball bearing 502 and the support rod 402 are pushed away from the beam splitter body 104. After the beam splitter body 104 is installed, the second spring 603 on the elastic assembly applies elastic pressure to the support rod 402, causing the ball bearing 502 at the front end of the support rod 402 to abut against the beam splitter body 104. The abutment and pressure between the ball bearing 502 at the front end of the two sets of support rods 402 on the support assembly and the corresponding positions on the upper and lower sides of the beam splitter body 104 provides support and limits the beam splitter body 104 after it has been pushed and positioned.

[0046] Preferably, the rolling assembly includes a spherical groove 501 formed at the end of the support rod 402, and a ball bearing 502 for abutting against the surface of the beam splitter body 104 is rotatably connected inside the spherical groove 501.

[0047] It should be noted here that: through transmission, the ball 502 abuts against the beam splitter body 104. Subsequently, when the support rod 402 moves laterally, because the ball 502 and the beam splitter body 104 remain abutting, the ball 502 is subjected to force and rolls inside the spherical groove 501. Through the rolling action, the resistance generated during the lateral movement of the support rod 402 is reduced.

[0048] Preferably, the elastic component includes a sleeve 601 fixed to one end of the support rod 402 away from the spherical groove 501, a slide rod 602 slidably connected to the sleeve 601, one end of the slide rod 602 being fixed to the strip plate 401, and a second spring 603 being sleeved on the outside of the sleeve 601, with both ends of the second spring 603 abutting against the support rod 402 and the strip plate 401 respectively;

[0049] It should be noted that the sleeve 601 and the slide rod 602 facilitate the telescopic connection between the auxiliary support rod 402 and the strip plate 401, and the second spring 603 facilitates the elastic push of the support rod 402.

[0050] Preferably, the connecting assembly includes a U-shaped plate 701 disposed on one side of the mounting side plate 201, and two sets of connecting rods 702 arranged symmetrically connected to the two sets of strip plates 401, with the connecting rods 702 fixed to the U-shaped plate 701;

[0051] It should be noted here that the U-shaped plate 701 and the connecting rod 702 facilitate the connection of the strip plate 401, and the two sets of connecting rods 702 guide the movement of the strip plate 401 after being subjected to force.

[0052] Preferably, the driving component is a miniature electric cylinder 8, which is installed and fixed on one side of the mounting side plate 201, and the output end of the miniature electric cylinder 8 is fixed to the U-shaped plate 701;

[0053] It should be noted here that the miniature electric cylinder 8 facilitates the movement and driving of the U-shaped plate 701;

[0054] In addition, a temperature sensor and a controller are installed inside the housing 101. The miniature electric cylinder 8, the temperature sensor and the controller are electrically connected. The temperature sensor monitors the temperature inside the housing 101 in real time and controls the miniature electric cylinder 8 according to the monitored temperature. The miniature electric cylinder 8, the temperature sensor and the controller are conventional drive components, temperature recognition components and control components. Their working principle and control method are well known technologies and will not be described in detail here.

[0055] Preferably, the adjustment assembly includes a transmission plate 901 fixed to one side of the mounting side plate 201. The transmission plate 901 has two sets of symmetrically arranged inclined slots 902. Transmission pins 903 are slidably connected to the two sets of inclined slots 902. Fixing brackets 904 are fixed on opposite sides of the two sets of strip plates 401. The two sets of transmission pins 903 are respectively fixed on the two sets of fixing brackets 904.

[0056] It should be noted that during the movement of the strip plate 401, the fixed frame 904 and the transmission pin 903 on the fixed frame 904 move laterally in sync. During the lateral movement of the transmission pin 903, the interaction between the inclined groove 902 on the transmission plate 901 and the transmission pin 903 drives the two sets of strip plates 401 to move longitudinally towards each other while moving laterally. During the mutual approach movement of the two sets of strip plates 401, the ball bearing 502 at the front end of the support rod 402 abuts against the surface of the beam splitter body 104, causing the strip plate 401 to retract relative to the support rod 402. During the relative retraction movement, the sliding rod 602 is pushed to slide on the sleeve 601 and the second spring 603 is further deformed to generate greater elastic force. Through the elastic force of the second spring 603, the ball bearing 502 at the front end of the support rod 402 is pushed to abut against the surface of the beam splitter body 104 with greater force.

[0057] In this solution: an LED lamp concentrator beam splitter structure includes the following steps:

[0058] When using the LED light concentrator, the beam splitter body 104 is pre-installed inside the housing 101. During installation, the positioning rod 303 is first pulled upward by the baffle 304 to ensure that the positioning rod 303 does not obstruct the insertion of the beam splitter body 104. During the upward pulling of the positioning rod 303, the first spring 305 deforms under force, generating elasticity. After the positioning rod 303 is pulled upward, the beam splitter body 104 is pushed between the slots 202 of the two sets of mounting side plates 201 for installation. During the insertion process, the positioning hole 301 on the beam splitter body 104 is connected to the sliding hole 302 on the mounting side plate 201. After the beam splitter body 104 is pushed in, the upward pull on the positioning rod 303 is released, and the positioning rod 303 is reset under the elastic force of the first spring 305. During the reset process, one end of the positioning rod 303 passes through the positioning hole 301 of the beam splitter body 104. Through the interaction between the positioning rod 303 and the positioning hole 301, the beam splitter body 104 is positioned after being pushed in and installed, which facilitates the accurate installation and use of the beam splitter body 104.

[0059] During the installation of the beam splitter body 104, the pushing end of the beam splitter body 104 abuts against the ball bearing 502 at the front end of the support rod 402 on the support assembly. During this abutment, the ball bearing 502 and the support rod 402 are pushed away from the beam splitter body 104. After the beam splitter body 104 is installed, the elastic compression of the support rod 402 by the second spring 603 on the elastic assembly causes the ball bearing 502 at the front end of the support rod 402 to abut against the beam splitter body 104. The abutment and compression between the ball bearings 502 at the front ends of the two sets of support rods 402 on the support assembly and the corresponding positions on the upper and lower sides of the beam splitter body 104 provides support and limits the beam splitter body 104 after it has been pushed and positioned (see [reference]). Figure 10 (in its state), through the support and limiting function, it is easy to use the beam splitter body 104 more stably after installation;

[0060] After installation, the beam splitter body 104, in conjunction with the optical unit 102 and the focusing unit 103, performs beam splitting. During beam splitting, due to the thinness of the beam splitter body 104, the propagation path of light within it is shortened, reducing material absorption loss (under the same LED power). More light can be converted into effective illumination light, achieving energy saving. Furthermore, the thinner beam splitter body 104 causes an increase in internal temperature of the housing 101 during beam splitting. To prevent warping of the beam splitter body 104 under high temperature, a micro-electric cylinder 8 drives two sets of U-shaped plates 701 to move closer to the two sets of mounting side plates 201. During the movement of the U-shaped plates 701, the connecting rod 702 drives the two sets of strip plates 401 on the support assembly to move. During the movement of the strip plates 401, the elastic component connects them... The function is to drive the support rod 402 towards the center of the beam splitter body 104 and maintain its support on the corresponding positions on the upper and lower sides of the beam splitter body 104. Because the center of the beam splitter body 104 lacks support, it is prone to warping at high temperatures. By centering the support position of the support component (sliding a distance, not directly in the center, to avoid interference with the optical path), the probability of warping of the beam splitter body 104 at high temperatures is reduced (during the entire centering movement, the travel path position is not in the optical area, so it does not block the beam splitting). In addition, during the movement of the strip plate 401, it drives the fixing frame 904 and the transmission pin 903 on the fixing frame 904 to move laterally synchronously. During the lateral movement of the transmission pin 903, through the interaction between the inclined groove 902 on the transmission plate 901 and the transmission pin 903, the two sets of strip plates 401 are driven to move longitudinally closer to each other while moving laterally (see...). Figure 11 During the transmission process, as the two sets of strip plates 401 move closer to each other, the ball bearing 502 at the front end of the support rod 402 abuts against the surface of the beam splitter body 104, causing the strip plates 401 to retract relative to the support rod 402. During this retraction, the sliding rod 602 slides on the sleeve 601, causing the second spring 603 to deform further and generate greater elastic force. Through the elastic force of the second spring 603, the ball bearing 502 at the front end of the support rod 402 abuts against the surface of the beam splitter body 104 with greater force, ensuring the anti-warping support effect. Subsequently, when the internal temperature of the housing 101 returns to normal, the U-shaped plate 701 and the strip plates 401 are reset through transmission. During the reset process, the elastic support force on the beam splitter body 104 is reduced through reverse transmission, preventing damage to the corresponding position on the beam splitter body 104 due to long-term high elastic support.
