Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a high-efficiency heat-dissipating COB light source module with adjustable color temperature. Background Art

[0002] With the rapid development of LED technology, the market demand for lighting applications has gradually diversified, especially the demand for adjustable color temperature lighting products. Such products have become a popular choice in the market. The mainstream color temperature adjustment lighting solution usually relies on mixing low color temperature LED light sources with high color temperature LED light sources to achieve lighting effects with different color temperatures. However, the existing mixing technology still has certain limitations, because the change in color temperature mainly depends on the ratio of the two LED light sources in the mixed light source. In this case, the arrangement of the dual color temperature chips on the substrate mirror directly affects the mixing effect.

[0003] Specifically, although a certain color-mixing light source can be obtained by stimulating dual-color temperature chips in different arrangements, the adjustment range is relatively limited due to the single color temperature category when mixing colors. This limitation makes the existing products obviously insufficient in expressing the concept of intelligent manufacturing.

[0005] The installation structure of the lamp relies on replacing different types of lamp heads to achieve the conversion of color temperature. However, this operation process is relatively cumbersome and often requires users to disassemble and install lamp heads, which reduces the convenience and flexibility of use to a certain extent. When adjusting the color temperature, users not only need to prepare a variety of lamp heads, but also need to carefully install and calibrate them, which is not only time-consuming but also prone to misoperation, thus affecting the lighting effect. In addition, frequent replacement of lamp heads may increase the wear and tear of the lamp and reduce its service life. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the present application provides: a high-efficiency heat dissipation COB light source module with adjustable color temperature, comprising a substrate 1, a low color temperature light source board 2, a high color temperature light source board 3, a low color temperature attenuation filter 4, a high color temperature attenuation filter 5, a high color temperature attenuation regulator 6 and a low color temperature attenuation regulator 7, the low color temperature light source board 2 and the high color temperature light source board 3 are both arranged at the bottom of the substrate 1; the low color temperature light source board 2 has a low color temperature light emitting area away from the substrate 1, and the high color temperature light source board 3 has a high color temperature light emitting area away from the substrate 1; the low color temperature attenuation filter 4 is arranged in the low color temperature light emitting area and can be relatively low color temperature The light source board 2 moves, and the high color temperature attenuation filter 5 is arranged in the high color temperature light emitting area and can move relative to the high color temperature light source board 3; the high color temperature attenuation regulator 6 is arranged between the high color temperature light source board 3 and the substrate 1 and is connected to the high color temperature attenuation filter 5, and the high color temperature attenuation regulator 6 is used to adjust the distance between the high color temperature attenuation filter 5 and the high color temperature light source board 3; the low color temperature attenuation regulator 7 is arranged between the low color temperature light source board 2 and the substrate 1 and is connected to the low color temperature attenuation filter 4, and the low color temperature attenuation regulator 7 is used to adjust the distance between the low color temperature attenuation filter 4 and the low color temperature light source board 2.

[0033] The low color temperature light source board 2 and the high color temperature light source board 3 are powered on at the same time, and the combined light source generated by the low color temperature light source board 2 and the high color temperature light source board 3 jointly affects the environment.

[0034] If the color temperature of the combined light source needs to be made cooler, the brightness of the high color temperature light source board 3 is increased, or the brightness of the low color temperature light source board 2 is reduced; if the color temperature of the combined light source needs to be made warmer, the brightness of the low color temperature light source board 2 is increased, or the brightness of the high color temperature light source board 3 is reduced.

[0035] The present application provides a high-efficiency heat dissipation type adjustable color temperature COB light source module, which aims to achieve color temperature adjustment of ambient lighting by flexibly adjusting the brightness of a low color temperature light source board 2 and a high color temperature light source board 3.

[0036] It should be noted that the attenuation effect of the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5 on light weakens as the distance increases. The optical properties of the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5, such as transmittance, remain unchanged, but as the distance increases, the influence of the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5 on the passing light beam will weaken, resulting in an increase in the light intensity of the light source passing through the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5. Therefore, adjusting the distance between the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5 and the light source will affect the light intensity passing through the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5, thereby adjusting the actual light brightness.

[0037] In the light source module, the low color temperature light source board 2 and the high color temperature light source board 3 are both arranged at the bottom of the substrate 1, and the light-emitting areas of the two are away from the substrate 1. On the low color temperature light source board 2, the low color temperature light-emitting area produces warm light, while the high color temperature light source board 3 emits light with a cool tone. When the two work together, a combined light source is generated, which affects the overall color temperature of the environment. When the low color temperature and high color temperature light source boards 3 are powered on at the same time, the required ambient color temperature can be achieved by adjusting their brightness. For example, when a colder light source is needed, the brightness of the high color temperature light source board 3 is increased, or it is achieved by reducing the brightness of the low color temperature light source board 2. On the contrary, when a warmer light source is needed, the color temperature of the combined light source is adjusted by increasing the brightness of the low color temperature light source board 2, or reducing the brightness of the high color temperature light source board 3.

[0038] In order to accurately control the color temperature, the low color temperature attenuation filter 4 and the high color temperature attenuation filter 5 are respectively arranged in the low color temperature and high color temperature light-emitting areas, and can be moved relative to their respective light source panels. The adjustment of these filters can effectively attenuate the brightness of the light source and further adjust the color temperature of the light source. Specifically, the low color temperature attenuation filter 4 is arranged in the low color temperature light-emitting area, and its spacing relative to the low color temperature light source panel 2 is adjusted by the low color temperature attenuation regulator 7. The high color temperature attenuation filter 5 is arranged in the high color temperature light-emitting area, and its spacing relative to the high color temperature light source panel 3 is adjusted by the high color temperature attenuation regulator 6. In this way, the brightness of the low color temperature and high color temperature light sources can be adjusted independently, thereby accurately controlling the color temperature of the combined light source.

[0039] The high color temperature attenuation regulator 6 is located between the high color temperature light source board 3 and the substrate 1, and is connected to the high color temperature attenuation filter 5. Its main function is to adjust the distance between the filter and the high color temperature light source board 3, so as to control the brightness and color temperature of the high color temperature part. Similarly, the low color temperature attenuation regulator 7 is located between the low color temperature light source board 2 and the substrate 1, and is connected to the low color temperature attenuation filter 4, and is used to adjust the brightness and color temperature of the low color temperature part.

[0040] like Figure 4 As shown, the low color temperature light source board 2 is disc-shaped, the high color temperature light source board 3 is ring-shaped and is coaxially arranged with the low color temperature light source board 2, and the bottom end of the substrate 1 is provided with an inner connecting column 11 and an outer connecting column 12 extending downward, the bottom end of the inner connecting column 11 is fixedly connected to the top end of the low color temperature light source board 2, and the bottom end of the outer connecting column 12 is fixedly connected to the top end of the high color temperature light source board 3.

[0041] In the design of the present invention, the low color temperature light source board 2 is disc-shaped and has a wide light-emitting area, while the high color temperature light source board 3 is ring-shaped and arranged around the outer edge of the low color temperature light source board 2, and the two are coaxially aligned. The bottom end of the substrate 1 is designed with an inner connecting column 11 and an outer connecting column 12. The inner connecting column 11 is located in the central part of the low color temperature light source board 2, and the bottom end is fixedly connected to the top of the low color temperature light source board 2 to ensure that the low color temperature light source board 2 is stably supported on the substrate 1. The outer connecting column 12 is located in the outer circle of the high color temperature light source board 3, and the bottom end is fixedly connected to the top of the high color temperature light source board 3 to form a stable supporting structure.

[0042] This structural design not only ensures a stable connection between the two light source boards, but also maximizes the light source effect and collaboration between the light source boards through coaxial arrangement. The relative positions of the low color temperature light source board 2 and the high color temperature light source board 3 are precisely designed to ensure that their light can be intertwined at an ideal angle, thereby producing the desired color temperature effect in the combined light source.

[0043] like Figure 5 , Figure 7 and Figure 8 As shown, the high color temperature attenuation regulator 6 includes an outer driving cylinder 61, an outer rotating driving member 62 and an outer adjusting cylinder 63. The outer driving cylinder 61 is rotatably arranged between the high color temperature light source board 3 and the substrate 1. The outer driving cylinder 61 is coaxial with the high color temperature light source board 3. The outer peripheral wall of the outer driving cylinder 61 is provided with outer guide pins 611 distributed along its circumference, and the outer guide pins 611 extend radially along the outer driving cylinder 61; the outer adjusting cylinder 63 is coaxial with the high color temperature light source board 3 and is slidably arranged at the bottom of the substrate 1, the inner peripheral wall of the outer adjusting cylinder 63 is slidably matched with the outer peripheral wall of the high color temperature light source board 3, the inner peripheral wall of the outer adjusting cylinder 63 is provided with outer arc grooves 631 distributed along its circumference, the outer guide pins 611 extend into the outer arc grooves 631 and slidably cooperate with them, the high color temperature attenuation filter 5 is coaxially arranged in an annular shape at the bottom end of the outer adjusting cylinder 63, and the high color temperature attenuation filter 5 is located at the bottom of the high color temperature light-emitting board.

[0044] The outer drive cylinder 61 is rotatably disposed between the high color temperature light source board 3 and the substrate 1, and is coaxial with the high color temperature light source board 3 to ensure a stable mechanical connection. The outer peripheral wall of the outer drive cylinder 61 is provided with outer guide pins 611 distributed along its circumference, and these outer guide pins 611 extend along the radial direction of the outer drive cylinder 61, which can effectively guide the smooth movement in the subsequent adjustment process.

[0045] The outer adjustment cylinder 63 is coaxial with the high color temperature light source board 3 and is slidably arranged at the bottom of the substrate 1. Its inner peripheral wall is slidably matched with the outer peripheral wall of the high color temperature light source board 3 to ensure that the outer adjustment cylinder 63 can accurately move axially during the adjustment process. The inner peripheral wall of the outer adjustment cylinder 63 is designed with an outer arc groove 631 distributed along its circumference, and the outer arc groove 631 cooperates with the outer guide pin 611. The outer guide pin 611 extends from the outer driving cylinder 61 to the arc groove of the outer adjustment cylinder 63, and slides with the outer arc groove 631. Because the outer adjustment cylinder 63 can only move in the longitudinal direction, when the outer driving cylinder 61 drives the outer guide pin 611 to rotate, the outer adjustment cylinder 63 can move smoothly in the longitudinal direction under the action of the outer guide pin 611, and achieves precise adjustment.

[0046] The high color temperature attenuation filter 5 is arranged at the bottom end of the outer adjustment tube 63. The high color temperature attenuation filter 5 is designed in an annular shape and is located at the bottom of the high color temperature light source board 3, and works together with it to attenuate the high color temperature light emitted by the light source. By adjusting the position of the outer adjustment tube 63, the outer guide pin 611 cooperates with the outer arc groove 631 to achieve the precise change of the distance between the attenuation filter and the high color temperature light source board 3, thereby controlling the brightness and color temperature of the light source.

[0047] like Figure 5 As shown, the bottom end of the base plate 1 is also provided with an outer positioning rod 13 extending downward, the bottom end of the outer positioning rod 13 is provided with an outer limiting ring 14 coaxial with the outer adjustment tube 63, the top end of the outer adjustment tube 63 is provided with an outer connecting ear 632 distributed along its circumference, and the outer positioning rod 13 slides through the outer connecting ear 632.

[0048] The bottom end of the base plate 1 is also provided with an outer positioning rod 13 extending downward to ensure the stability and accuracy of the entire adjustment structure. The bottom end of the outer positioning rod 13 is equipped with an outer limit ring 14 coaxial with the outer adjustment cylinder 63. The outer limit ring 14 is designed to prevent the outer adjustment cylinder 63 from excessive displacement during the adjustment process, thereby ensuring its smooth movement and positioning accuracy within the working range. The coaxial cooperation between the outer limit ring 14 and the outer adjustment cylinder 63 ensures that the movement of the outer adjustment cylinder 63 always remains within the designed track to avoid unnecessary deviation.

[0049] In addition, the top of the outer adjustment tube 63 is provided with a plurality of outer connection ears 632 evenly distributed along its circumference, and these connection ears play a role in strengthening the fixing between the outer adjustment tube 63 and the outer positioning rod 13. The design of the outer connection ear 632 not only improves the firmness of the regulator structure, but also provides a stable sliding channel for the outer positioning rod 13. The outer positioning rod 13 slides through the outer connection ear 632 to ensure that the outer adjustment tube 63 can be accurately adjusted without losing balance. Through this design, the cooperation between the outer positioning rod 13 and the outer connection ear 632 realizes the effective guidance of the movement of the outer adjustment tube 63, avoiding mechanical failure or misoperation caused by excessive displacement.

[0050] like Figure 5 As shown, an outer elastic element 81 is also sleeved on the outer positioning rod 13 , and the outer elastic element 81 is located between the outer limiting ring 14 and the outer connecting ear 632 .

[0051] An outer elastic element 81 is also sleeved on the outer positioning rod 13, and the outer elastic element 81 is located between the outer limiting ring 14 and the outer connecting ear 632. The main function of the outer elastic element 81 is to provide an elastic buffer mechanism to reduce the impact or vibration that may be generated by the outer adjustment cylinder 63 during the adjustment process, ensuring that the system can operate smoothly. The outer elastic element 81 can effectively absorb external forces or load fluctuations, play a role in shock absorption and protection, prevent excessive force from being transmitted to the precise adjustment components, and extend the service life of the adjustment system.

[0052] like Figure 5 As shown, the external rotating driving member 62 includes an outer bevel gear ring 621, an outer bevel gear 622 and an outer servo motor 623. The outer bevel gear ring 621 is coaxially arranged on the inner circumferential wall of the outer driving cylinder 61; the outer bevel gear 622 is rotatably arranged between the high color temperature light source board 3 and the substrate 1, and the outer bevel gear 622 is meshed with the outer bevel gear ring 621; the external servo motor 623 is fixedly arranged between the high color temperature light source board 3 and the substrate 1, and the output shaft of the external servo motor 623 is coaxially fixedly connected with the outer bevel gear 622.

[0053] The outer cone gear ring 621 is coaxially arranged on the inner circumferential wall of the outer drive cylinder 61 to ensure that it can maintain stable coaxial alignment with other components during rotation. The inner and outer tooth surfaces of the outer cone gear ring 621 are precisely designed to achieve efficient power transmission during rotation while maintaining low friction and high stability, reducing system wear and increasing service life.

[0054] The outer bevel gear 622 is rotatably disposed between the high color temperature light source board 3 and the substrate 1, and serves as a key component for power transmission between the outer bevel gear ring 621 and the high color temperature light source board 3. The outer bevel gear 622 is precisely meshed with the outer bevel gear ring 621, and the rotation of the outer drive cylinder 61 is realized through gear transmission, thereby driving the high color temperature light source board 3 for precise adjustment.

[0055] The external servo motor 623 is fixedly arranged between the high color temperature light source panel 3 and the substrate 1, and serves as a power source for the external rotary drive member 62. The external servo motor 623 provides precise speed control and torque output, and drives the external bevel gear 622 through the coaxial connection between its output shaft and the external bevel gear 622.

[0056] like Figure 6 , Fig. 9 and Fig.10As shown, the low color temperature attenuation regulator 7 includes an inner driving cylinder 71, an inner rotating driving member and an inner adjusting cylinder 73. The inner driving cylinder 71 is rotatably arranged between the low color temperature light source board 2 and the substrate 1. The inner driving cylinder 71 is coaxial with the low color temperature light source board 2. The outer peripheral wall of the inner driving cylinder 71 is provided with inner guide pins 711 distributed along its circumference. The inner guide pins 711 extend along the radial direction of the inner driving cylinder 71. The inner adjusting cylinder 73 is coaxial with the high color temperature light source board 3 and is slidably arranged at the bottom of the substrate 1. The inner circumferential wall of the inner adjustment cylinder 73 is slidably matched with the outer circumferential wall of the low color temperature light source panel 2, and the outer circumferential wall of the inner adjustment cylinder 73 is slidably matched with the inner circumferential wall of the low color temperature light source panel 2. The inner circumferential wall of the inner adjustment cylinder 73 is provided with an inner arc groove 731 distributed along its circumference, and the inner guide pin 711 extends into the inner arc groove 731 and slidably matches therewith. The low color temperature attenuation filter 4 is coaxially arranged in a disc shape at the bottom end of the inner adjustment cylinder 73, and the low color temperature attenuation filter 4 is located at the bottom of the low color temperature light-emitting panel.

[0057] The inner drive cylinder 71 is rotatably disposed between the low color temperature light source board 2 and the substrate 1, and is coaxially docked with the low color temperature light source board 2 to ensure consistent rotation during the adjustment process. A plurality of inner guide pins 711 are evenly distributed along the circumference of the outer peripheral wall of the inner drive cylinder 71, and the inner guide pins 711 cooperate with the guide structure in the inner adjustment cylinder 73 to ensure that the inner drive cylinder 71 can rotate stably and smoothly, avoiding unstable operation caused by eccentric or asymmetric loads.

[0058] The inner adjustment cylinder 73 is coaxial with the high color temperature light source panel 3 and is slidably arranged at the bottom of the substrate 1, and its inner peripheral wall forms a precise sliding fit with the outer peripheral wall of the low color temperature light source panel 2 and the inner peripheral wall forms a precise sliding fit with the inner peripheral wall of the low color temperature light source panel 2. This precision design ensures that the inner adjustment cylinder 73 can maintain a smooth movement trajectory during the adjustment process and achieves effective distance adjustment with the low color temperature light source panel 2. The inner peripheral wall of the inner adjustment cylinder 73 is provided with inner arc grooves 731 evenly distributed along its circumference. The inner arc grooves 731 play a guiding and positioning role during the adjustment process, and can effectively guide the inner guide pin 711 and ensure that it is stable and non-deflected during movement. The inner driving cylinder 71 drives the inner guide pin 711 to rotate, so that the inner adjustment cylinder 73 can be lifted and lowered in the longitudinal direction.

[0059] The low color temperature attenuation filter 4 is coaxially arranged at the bottom end of the inner adjustment tube 73 in a disc shape and is located at the bottom of the low color temperature light-emitting panel. The low color temperature attenuation filter 4 can adjust the intensity and color temperature of the attenuated light source as needed through the precise control of the inner adjustment tube 73, ensuring that the output of the low color temperature light source can be stably and accurately adjusted. The disc-shaped design of the low color temperature attenuation filter 4 and the close fit of the inner adjustment tube 73 ensure the high efficiency and reliability of the attenuation function.

[0060] like Figure 6As shown, the bottom end of the substrate 1 is also provided with an inner positioning rod 15 extending downward, the bottom end of the inner positioning rod 15 is fixedly connected to the top end of the high color temperature light source panel 3, and the top end of the inner adjustment cylinder 73 is provided with an inner connecting ear 732 distributed along its circumference, and the inner positioning rod 15 slides through the inner connecting ear 732.

[0061] The bottom end of the inner positioning rod 15 is firmly connected to the top end of the high color temperature light source board 3 to form a stable connection structure. This design ensures that the relative position between the high color temperature light source board 3 and the substrate 1 remains unchanged during the adjustment process, thereby avoiding position deviation caused by vibration or external interference, and ensuring the stability and accuracy of the system operation.

[0062] The top of the inner adjustment cylinder 73 is provided with a plurality of inner connection ears 732 evenly distributed along its circumference. The function of these inner connection ears 732 is to provide a stable connection point so that the inner positioning rod 15 can be accurately docked with the top of the inner adjustment cylinder 73. The circumferential distribution design of the inner connection ears 732 enables the adjuster to be adjusted at different positions without being restricted by directionality, thereby improving the flexibility and adaptability of the adjustment process.

[0063] The inner positioning rod 15 slides through the inner connecting ear 732 to ensure the smooth movement of the inner adjustment tube 73 during the adjustment process. Through this design, the sliding fit between the inner positioning rod 15 and the inner connecting ear 732 provides sufficient freedom, so that the inner adjustment tube 73 can slide smoothly on the substrate 1 and complete the adjustment task, while preventing the jamming or deviation caused by asymmetric force or improper operation.

[0064] like Figure 6 As shown, an inner elastic element 82 is sleeved on the inner positioning rod 15 , and the inner elastic element 82 is located between the high color temperature light source panel 3 and the inner connecting ear 732 .

[0065] The inner positioning rod 15 is also provided with an inner elastic element 82, which further enhances the adjustment performance and stability of the low color temperature attenuation regulator 7. The inner elastic element 82 is usually made of elastic materials such as springs, and is located between the high color temperature light source panel 3 and the inner connecting ear 732, playing the role of buffering, elastic support and displacement limitation. It can not only effectively absorb the impact force during the adjustment process, but also ensure that a certain pre-pressure is always maintained between the inner positioning rod 15 and the inner connecting ear 732, to prevent position deviation or inaccurate adjustment due to external disturbance or vibration.

[0066] like Figure 6 and Fig.10As shown, the inner rotating driving member includes an inner bevel gear ring 721, an inner bevel gear 722 and an inner servo motor 723. The inner bevel gear ring 721 is coaxially arranged on the inner circumferential wall of the inner driving cylinder 71; the inner bevel gear 722 is rotatably arranged between the low color temperature light source board 2 and the substrate 1, and the inner bevel gear 722 is meshed with the inner bevel gear ring 721; the inner servo motor 723 is fixedly arranged between the low color temperature light source board 2 and the substrate 1, and the output shaft of the inner servo motor 723 is coaxially fixedly connected with the inner bevel gear 722.

[0067] The inner cone gear ring 721 is coaxially arranged on the inner circumferential wall of the inner driving cylinder 71, and is designed to provide a stable support and power transmission platform. The precise positioning of the inner cone gear ring 721 enables the entire drive system to maintain good rotation stability and reliability under high load conditions.

[0068] The inner bevel gear 722 is rotatably disposed between the low color temperature light source board 2 and the substrate 1. The inner bevel gear 722 transmits power through meshing with the inner bevel gear ring 721, ensuring that the inner adjustment cylinder 73 can achieve smooth and accurate rotational motion during the adjustment process.

[0069] The inner servo motor 723 is fixedly arranged between the low color temperature light source board 2 and the substrate 1, and serves as the power source of the entire drive system. The inner servo motor 723 has high-precision control capability, and can accurately adjust the speed and direction as needed to ensure that the regulator maintains a constant power output during the entire adjustment process. The output shaft of the inner servo motor 723 is coaxially fixedly connected to the inner bevel gear 722, so that the rotational power output by the motor can be directly transmitted to the inner bevel gear 722, thereby driving the inner bevel gear ring 721 and the inner adjustment cylinder 73 to complete the required adjustment task.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
