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, market demand for lighting fixtures is increasingly diverse, with demand for color-temperature-adjustable lighting products becoming particularly prominent. These products have become a popular choice in the market. Mainstream color-temperature-adjustable lighting solutions typically rely on mixing low-color-temperature LEDs with high-color-temperature LEDs to achieve varying color temperature lighting effects. However, existing light-mixing technology still has limitations, as the color temperature variation depends primarily on the ratio of the two LED sources in the mix. In this case, the arrangement of the dual-color-temperature chips on the substrate mirror directly affects the light-mixing effect.

[0003] Specifically, while a certain degree of color mixing can be achieved by stimulating dual-color temperature chips arranged in different ways, the adjustment range is relatively limited due to the single color temperature category used in color mixing. This limitation makes existing products significantly inadequate in expressing the concept of intelligent manufacturing.

When assembled, the positive spring pin is electrically connected to the positive connection point, and the negative spring pin is electrically connected to the negative connection point; the heat conducting plate is provided on the connector, and the two sides of the heat conducting plate are respectively attached to the connector and the lamp holder.

[0005] The fixture's installation structure relies on replacing different lamp heads to achieve color temperature conversion. However, this process is cumbersome and often requires users to remove and install lamp heads, which reduces ease of use and flexibility. Adjusting the color temperature requires not only preparing multiple lamp heads but also meticulous installation and calibration, which is time-consuming and prone to misoperation, thus affecting the lighting effect. Furthermore, frequent lamp head replacement can increase wear and tear on the fixture, reducing its lifespan. Summary of the Invention

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] 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 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 adjuster 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 adjuster 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 adjuster 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 adjuster 7 is used to adjust the distance between the low color temperature attenuation filter 4 and the low color temperature light source board 2.

[0034] 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.

[0035] If the color temperature of the combined light source needs to be made cooler, the brightness of the high color temperature light source panel 3 is increased, or the brightness of the low color temperature light source panel 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 panel 2 is increased, or the brightness of the high color temperature light source panel 3 is reduced.

[0036] 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 the low color temperature light source board 2 and the high color temperature light source board 3.

[0037] It should be noted that the light attenuation effect of the low and high color temperature attenuation filters 4 and 5 decreases with increasing distance. While their optical properties, such as transmittance, remain unchanged, their influence on the passing light beam decreases with increasing distance, resulting in an increase in the intensity of the light passing through them. Therefore, adjusting the distance between the low and high color temperature attenuation filters 4 and 5 and the light source affects the intensity of the light passing through them, thereby adjusting the actual brightness of the light.

[0038] In this 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 cool light. 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 cooler light source is needed, the brightness of the high color temperature light source board 3 is increased, or it can be achieved by reducing the brightness of the low color temperature light source board 2. Conversely, 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.

[0039] 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 boards. 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 board 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 board 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.

[0040] 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 primary function is to adjust the distance between the filter and the high color temperature light source board 3, thereby controlling the brightness and color temperature of the high color temperature portion. 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, used to adjust the brightness and color temperature of the low color temperature portion.

[0041] 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 annular 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.

[0042] In the design of the present invention, the low color temperature light source panel 2 is disc-shaped and has a wide light-emitting area, while the high color temperature light source panel 3 is annular and is arranged around the outer edge of the low color temperature light source panel 2, and the two are coaxially aligned. The bottom end of the substrate 1 is designed with an internal connecting column 11 and an external connecting column 12. The internal connecting column 11 is located in the center part of the low color temperature light source panel 2, and the bottom end is fixedly connected to the top of the low color temperature light source panel 2 to ensure that the low color temperature light source panel 2 is stably supported on the substrate 1. The external connecting column 12 is located on the outer ring of the high color temperature light source panel 3, and the bottom end is fixedly connected to the top of the high color temperature light source panel 3 to form a stable support structure.

[0043] This structural design not only ensures a secure connection between the two light source panels, but also, through coaxial arrangement, maximizes the synergistic effect of the light source panels. The relative positions of the low color temperature light source panel 2 and the high color temperature light source panel 3 are precisely designed to ensure that their light can interweave at an ideal angle, thereby producing the desired color temperature effect in the combined light source.

[0044] 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. The outer guide pins 611 extend along the radial direction of 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 match therewith. The high color temperature attenuation filter 5 is coaxially arranged in an annular shape at the bottom end of the outer adjusting cylinder 63. The high color temperature attenuation filter 5 is located at the bottom of the high color temperature light-emitting board.

[0045] The outer drive cylinder 61 is rotatably disposed between the high color temperature light source panel 3 and the base plate 1, and is coaxial with the high color temperature light source panel 3, ensuring 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. These outer guide pins 611 extend radially along the outer drive cylinder 61, effectively guiding smooth movement during subsequent adjustments.

[0046] The outer adjustment cylinder 63 is coaxial with the high color temperature light source panel 3 and is slidably arranged at the bottom of the substrate 1. Its inner peripheral wall slides with the outer peripheral wall of the high color temperature light source panel 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 outer arc grooves 631 distributed along its circumference, and the outer arc grooves 631 cooperate with the outer guide pins 611. The outer guide pins 611 extend from the outer driving cylinder 61 to the arc grooves of the outer adjustment cylinder 63 and slide with the outer arc grooves 631. Because the outer adjustment cylinder 63 can only move in the longitudinal direction, when the outer driving cylinder 61 drives the outer guide pins 611 to rotate, the outer adjustment cylinder 63 can move smoothly in the longitudinal direction under the action of the outer guide pins 611 and achieve precise adjustment.

[0047] The high color temperature attenuation filter 5 is mounted at the bottom of the outer adjustment tube 63. This ring-shaped filter 5 sits at the bottom of the high color temperature light source board 3, working in conjunction 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 and the outer arcuate groove 631 precisely adjust 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.

[0048] like Figure 5 As shown, the bottom end of the base plate 1 is also provided with an external positioning rod 13 extending downward, the bottom end of the external positioning rod 13 is provided with an external limiting ring 14 coaxial with the external adjustment tube 63, and the top end of the external adjustment tube 63 is provided with an external connecting ear 632 distributed along its circumference, and the external positioning rod 13 slides through the external connecting ear 632.

[0049] The base plate 1 also features a downward-extending outer positioning rod 13 at its bottom end, ensuring the stability and precision of the entire adjustment mechanism. The bottom end of the outer positioning rod 13 is fitted with an outer stop ring 14, coaxial with the outer adjustment cylinder 63. This ring is designed to prevent excessive displacement of the outer adjustment cylinder 63 during adjustment, ensuring smooth movement and precise positioning within the operating range. The coaxial fit of the outer stop ring 14 with the outer adjustment cylinder 63 ensures that the cylinder 63 remains within its designed trajectory, preventing unwanted deviation.

[0050] In addition, the top end of the outer adjustment tube 63 is provided with a plurality of outer connecting ears 632 evenly distributed along its circumference. These connecting ears play a role in strengthening the fixation between the outer adjustment tube 63 and the outer positioning rod 13. The design of the outer connecting ears 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 connecting ears 632, ensuring that the outer adjustment tube 63 can be precisely adjusted without losing balance. Through this design, the cooperation between the outer positioning rod 13 and the outer connecting ears 632 realizes the effective guidance of the movement of the outer adjustment tube 63, avoiding mechanical failure or misoperation caused by excessive displacement.

[0051] like Figure 5 As shown, an outer elastic element 81 is further 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 .

[0052] An external elastic element 81 is also mounted on the outer positioning rod 13 and positioned between the outer retaining ring 14 and the outer connecting lug 632. This element provides a resilient buffering mechanism to reduce the impact or vibration that may occur during the adjustment process of the outer adjustment cylinder 63, ensuring smooth system operation. This element effectively absorbs external forces or load fluctuations, providing both shock absorption and protection, preventing excessive force from being transmitted to delicate adjustment components and extending the service life of the adjustment system.

[0053] 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 engaged 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 to the outer bevel gear 622.

[0054] The outer bevel gear ring 621 is coaxially mounted on the inner circumference of the outer drive cylinder 61, ensuring stable coaxial alignment with the other components during rotation. The precision-engineered inner and outer tooth surfaces of the outer bevel gear ring 621 enable efficient power transmission during rotation while maintaining low friction and high stability, reducing system wear and extending service life.

[0055] The outer bevel gear 622 is rotatably disposed between the high color temperature light source panel 3 and the base plate 1, serving as a key component for transmitting power between the outer bevel gear ring 621 and the high color temperature light source panel 3. The outer bevel gear 622 precisely meshes with the outer bevel gear ring 621, and through gear transmission, the outer drive cylinder 61 is rotated, thereby driving the precise adjustment of the high color temperature light source panel 3.

[0056] The external servo motor 623 is fixedly disposed between the high color temperature light source panel 3 and the base plate 1 and serves as the 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.

[0057] like Figure 6 、 Figure 9 and Figure 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 slides 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 slides 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 slides with it. 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.

[0058] The inner drive cylinder 71 is rotatably positioned between the low color temperature light source panel 2 and the base plate 1, coaxially docking with the panel 2 to ensure consistent rotation during adjustment. Multiple inner guide pins 711 are evenly distributed along the outer circumference of the inner drive cylinder 71. These inner guide pins 711 engage with guide structures within the inner adjustment cylinder 73, ensuring stable and smooth rotation of the inner drive cylinder 71 and preventing operational instability caused by eccentric or asymmetric loads.

[0059] 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 between it and 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 uniformly 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 without deviation during movement. The inner drive cylinder 71 drives the inner guide pin 711 to rotate, so that the inner adjustment cylinder 73 can be raised and lowered in the longitudinal direction.

[0060] The disc-shaped low color temperature attenuating filter 4 is coaxially positioned at the bottom end of the inner adjustment tube 73 and located at the base of the low color temperature light-emitting panel. Through the precise control of the inner adjustment tube 73, the low color temperature attenuating filter 4 can adjust the intensity and color temperature of the attenuated light source as needed, ensuring stable and precise regulation of the low color temperature light source's output. The disc-shaped design of the low color temperature attenuating filter 4, in close coordination with the inner adjustment tube 73, ensures efficient and reliable attenuation.

[0061] 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.

[0062] 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, forming a stable connection structure. This design ensures that the relative position between the high color temperature light source board 3 and the base plate 1 remains unchanged during the adjustment process, thus preventing position shifting due to vibration or external interference, and ensuring the stability and accuracy of system operation.

[0063] The top of the inner adjustment cylinder 73 is equipped with multiple inner connecting lugs 732 evenly distributed along its circumference. These lugs 732 provide a stable connection point, allowing the inner positioning rod 15 to precisely mate with the top of the inner adjustment cylinder 73. The circumferential distribution of the lugs 732 allows the adjuster to be adjusted in different positions without directional restrictions, thereby improving the flexibility and adaptability of the adjustment process.

[0064] The inner positioning rod 15 slides through the inner connecting ear 732, ensuring smooth movement of the inner adjustment cylinder 73 during adjustment. This design provides sufficient freedom for the sliding fit between the inner positioning rod 15 and the inner connecting ear 732, allowing the inner adjustment cylinder 73 to slide smoothly on the substrate 1 and complete the adjustment task, while preventing jamming or deviation caused by asymmetric forces or improper operation.

[0065] 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 .

[0066] An internal elastic element 82 is also sleeved onto the inner positioning rod 15, further enhancing the adjustment performance and stability of the low color temperature attenuation adjuster 7. Typically made of an elastic material such as a spring, the internal elastic element 82 is located between the high color temperature light source panel 3 and the inner connecting lug 732, providing cushioning, elastic support, and displacement restriction. This not only effectively absorbs impact forces during adjustment but also ensures a constant preload between the inner positioning rod 15 and the inner connecting lug 732, preventing positional drift or inaccurate adjustment due to external disturbances or vibration.

[0067] like Figure 6 and Figure 10As shown, the inner rotating drive 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 engaged 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.

[0068] The inner bevel gear ring 721 is coaxially mounted on the inner circumference of the inner drive cylinder 71, providing a stable support and power transmission platform. The precise positioning of the inner bevel gear ring 721 enables the entire drive system to maintain excellent rotational stability and reliability under high load conditions.

[0069] The inner bevel gear 722 is rotatably disposed between the low color temperature light source panel 2 and the base plate 1. The inner bevel gear 722 transmits power by meshing with the inner bevel gear ring 721, ensuring that the inner adjustment cylinder 73 can achieve smooth and accurate rotation during the adjustment process.

[0070] The internal servo motor 723 is fixedly mounted between the low color temperature light source panel 2 and the base plate 1, serving as the power source for the entire drive system. The internal servo motor 723 possesses high-precision control capabilities, enabling precise adjustment of speed and direction as needed, ensuring that the regulator maintains a constant power output throughout the entire adjustment process. The output shaft of the internal servo motor 723 is coaxially and fixedly connected to the internal bevel gear 722, allowing the motor's rotational power to be directly transmitted to the internal bevel gear 722, thereby driving the internal bevel gear ring 721 and the internal adjustment cylinder 73 to complete the required adjustment task.

[0071] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
