[0015] A voltage-regulated light source module and its dimming and color-tuning method, including The color temperature control module and the light intensity control module are connected in parallel in the circuit. A sliding rheostat is connected in series on the color temperature switching module in the color temperature control module; According to the control amount of the power supply voltage, the overall control voltage on the color temperature control module and the light intensity control module is controlled; The power supply voltage acts on the electromagnet on the light intensity control module. According to the control amount of the power supply voltage, the magnetic force of the electromagnet is changed to adjust the light output of the light source module; The power supply voltage acts on the color temperature switching module and the sliding rheostat on the color temperature control module.

[0016] Compared with the prior art, the present invention provides a voltage-regulated light source module and its dimming and color mixing method, having the following beneficial effects: 1. For this voltage-regulated light source module, through the modularized light source module, it can be freely installed in the circuit board to freely change the maximum intensity of the light source. According to the use environment, the light source modules can be freely added or reduced. That is, if high battery life is required, the number of light source modules can be reduced; if high illumination intensity is required, the number of light source modules needs to be increased, providing more choices for users. Moreover, the modularized setting also allows for quick disassembly and assembly, facilitating replacement.
[0017] 2. For this voltage-regulated light source module, after the lamp beads are used for a long time, the phenomenon of temperature rise will occur. When the temperature rises to a certain level, there is a possibility of lamp bead damage. Through the setting of the temperature-sensitive rod, high temperature will cause the shape memory alloy to deform and contract, compress the reset spring, drive the contact rod to disengage from the start switch inside the temperature-sensitive rod, and turn off all the lamp beads on this side until the temperature returns to normal and the contact rod reconnects to the start switch to turn on the lamp beads, thereby protecting the lamp beads from damage due to excessive temperature.
[0018] 3. For this voltage-regulated light source module and its dimming and color mixing method, by applying a variable voltage to the electromagnet, the magnetic force intensity of the electromagnet can be changed to adsorb the magnetic slider for displacement. The number of contact switches contacted by the displacement of the magnetic slider is used to control the number of lamp beads turned on, thereby controlling the intensity of the light source. Therefore, the light source module can dynamically control the light source intensity through the magnitude of the voltage. By changing the voltage, the color temperature switching module drives the gear to rotate, and then drives the contact slider to slide through the switch ring, so that the contact slider contacts the two side secondary sockets inside the light source plug board separately or not at all, thereby adjusting the warm and cold color temperature and on / off of the light source. Cooperating with the light intensity control module, the change of color temperature can be realized. That is, when it is cold color temperature, the intensity of the cold color is controlled by the number of lamp beads turned on to realize the adjustment of color temperature intensity. Through such mechanical displacements, etc., the light intensity and color temperature are adjusted to make the adjustment process more stable. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1
[0022] As Figures 1-9As shown in the figure, it includes a circuit board 10, on which at least one light source module is detachably arranged. A color temperature control module and a light intensity control module are also arranged inside the circuit board 10. At least one light source card slot 101 is opened on one end face of the circuit board 10. A card slot is arranged on the side of the light source card slot 101, and a power connection port is arranged in the card slot. The light source module is movably installed in the light source card slot 101 through the card slot, and the light source module is electrically connected to the power connection port, so that the circuit in the light source module can be connected. A chute 102 and a limiting groove 103 are opened at the bottom of the light source card slot 101. The chute 102 is arranged on both sides of the limiting groove 103. The circuit board 10 is a light source circuit board, which is circular or square. Through the modular light source module, it can be freely installed in the circuit board 10 to freely change the maximum intensity of the light source. The light source module can be freely added or reduced according to the use environment. That is, if high battery life is required, the number of light source modules can be reduced. If high illumination intensity is required, the number of light source modules needs to be increased, providing more choices for users.
[0023] The light source module includes a light source plug board 20. A temperature control switch is also arranged inside the light source plug board 20. A plurality of lamp beads 201 are arranged on one end face of the light source plug board 20. A contact switch 203 corresponding to the lamp beads 201 is arranged at the bottom of the light source plug board 20. A secondary socket 204 is also arranged on its side wall. The lamp beads 201 and the contact switches 203 on the light source plug board 20 are divided into two groups and correspond to each other one by one. The lamp beads 201 are electrically connected to the contact switches 203. Each lamp bead 201 and the contact switch 203 form a complete circuit. The corresponding lamp bead 201 can be started to light up and turned off through the contact switch 203. The temperature control switch is arranged inside the light source plug board 20 and is located between the two groups of lamp beads 201 and contact switches 203. A voltage stabilizing module 205 and a current stabilizing module 206 are also arranged inside the light source plug board 20. The temperature control switch is arranged on both sides of the voltage stabilizing module 205 and the current stabilizing module 206. Raised clamping blocks are arranged on both sides of the light source plug board 20. A support leg 202 is arranged at the end of the light source plug board 20. Part of the raised clamping blocks is arranged on the support leg 202. The temperature control switch includes a temperature sensing rod 30. A contact rod 301 is slidably arranged inside the temperature sensing rod 30. A shape memory metal 302 and a return spring 303 are fixed between the contact rod 301 and the inner wall of the temperature sensing rod 30. The return spring 303 is located on the outer peripheral side of the shape memory metal 302. An opening and closing switch is arranged inside the temperature sensing rod 30. The contact rod 301 contacts the opening and closing switch. After the lamp beads 201 are used for a long time, the temperature will rise. When the temperature rises to a certain level, there is a possibility that the lamp beads 201 will be damaged. Through the arrangement of the temperature sensing rod 30, the high temperature will cause the shape memory metal 302 to deform and contract, compress the return spring 303, and drive the contact rod 301 to disengage from the start switch inside the temperature sensing rod 30, turning off all the lamp beads 201 on this side until the temperature returns to normal and the contact rod 301 contacts the start switch again to turn on the lamp beads 201, so as to protect the lamp beads 201 from being damaged due to excessive temperature. In this embodiment, the normal operating temperature of the lamp beads is generally lower than 60 °C. If it is higher than 60 °C, the lamp beads will work in a high-temperature environment for a long time, greatly reducing their service life. When the temperature rises to 85 °C and above, there will be a risk of damage to the lamp beads 201. The triggering temperature of the shape memory metal 302 in the temperature sensing rod 30 is 60 - 85 °C. When the ambient temperature or the temperature near the lamp beads reaches 60 °C, the shape memory metal 302 begins to deform and contract. When the temperature approaches or exceeds 85 °C, the shape memory metal 302 completely deforms and contracts, driving the return spring 303 and the contact rod 301 to move to cut off the power supply of the lamp beads, realizing over-temperature protection for the lamp beads 201 and preventing them from being damaged due to overheating.
[0024] The light intensity control module includes an electromagnet 11 and a magnetic slider 12. The magnetic slider 12 is in contact with the contact switch 203. The magnetic slider 12 slides within the chute 102. The electromagnet 11 is installed at the inner center of the circuit base plate 10. Two magnetic sliders 12 form a group, and there is at least one group. The magnetic slider 12 slides within the circuit base plate 10. One end of it corresponds to the electromagnet 11, and the other end is installed on the inner wall of the circuit base plate 10 through a tension spring. By applying a variable voltage to the electromagnet 11, the magnetic force intensity of the electromagnet 11 can be changed, thereby changing the pulling force generated by adsorbing the magnetic slider 12. Then, under the combined action of the tension spring, the magnetic slider 12 can slide within the electromagnet 11. Thus, the number of turned-on lamp beads 201 can be controlled by the number of magnetic sliders 12 contacting the contact switch 203, that is, the intensity of the light source can be controlled. Therefore, the light source module can dynamically control the light source intensity by the magnitude of the voltage.
[0025] The color temperature control module includes a switch ring 13, a color temperature switching module 15, and a contact slider 16. The switch ring 13 is connected to the contact slider 16 through a limit pin 131. The contact slider 16 slides within the limit groove 103. A gear 14 is arranged within the color temperature switching module 15. A voltage driving component is arranged within the color temperature switching module 15, which is arranged similar to the internal structure of a voltmeter. The change in its voltage can generate a circular angular trajectory. Since this structure is a prior art, no more details will be described here. Thus, it can drive the gear 14 to rotate. The gear 14 meshes with the inner wall of the switch ring 13. The switch ring 13 is rotatably installed within the circuit base plate 10. There is at least one limit pin 131. A main socket 162 is arranged on the side wall of the contact slider 16. The main socket 162 cooperates with the secondary socket 204. A limit straight slot 161 is formed within the contact slider 16. The limit pin 131 is located within the limit straight slot 161 and slides within the limit straight slot 161. Since the contact slider 16 slides linearly along the tangent direction of the switch ring 13 within the circuit base plate 10, when the switch ring 13 drives the contact slider 16 to move, the limit straight slot 161 can prevent the two from being stuck. The contact slider 16 slides linearly within the circuit base plate 10. By changing the voltage, the color temperature switching module 15 drives the gear 14 to rotate. Thus, the switch ring 13 drives the contact slider 16 to slide within the limit groove 103, so that the contact slider 16 contacts the two secondary sockets 204 on both sides within the light source plug board 20 separately or does not contact them at all, thereby adjusting the warm and cold color temperature and turning on and off of the light source. Cooperating with the above light intensity control module, the change in color temperature can be realized, that is, when it is a cold color temperature, the intensity of the cold color is controlled by the number of turned-on lamp beads 201, and the adjustment of the color temperature intensity is realized.
[0026] Working principle: When in use, the components inside the circuit board 10 are electrically connected to a variable voltage power supply. When a cold color temperature is required, the voltage on the color temperature switching module 15 is adjusted to rotate the gear 14, which can drive the switch ring 13 to rotate. The contact slider 16 is driven to slide through the limit pin 131, so that the main socket 162 on the contact slider 16 is connected to the secondary socket 204, thereby connecting the cold color temperature circuit, starting the cold color temperature light source. Then, by adjusting the variable voltage power supply to change the voltage intensity on the electromagnet 11, the magnetism and adsorption force on the electromagnet 11 are changed, so that the magnetic slider 12 can be adsorbed to move against the elastic force of the tension spring, and it contacts different numbers of contact switches 203 to turn on different numbers of cold color temperature lamp beads 201.
[0027] When a warm color temperature is required, the voltage on the color temperature switching module 15 is adjusted to rotate it to the other side, so that the main socket 162 on the other side of the contact slider 16 contacts the secondary socket 204 on the other side, thereby connecting the warm color temperature circuit. Similarly, by adjusting the variable voltage power supply to change the voltage intensity on the electromagnet 11, the intensity of the warm color temperature is adjusted.
[0028] When the maximum light intensity of the light source is insufficient at this time, to increase the light intensity, the spare light source plug board 20 can be inserted into the light source card slot 101 to increase the overall number of lamp beads 201, thereby increasing the maximum light intensity of the light source. When long battery life is required, the redundant light source plug board 20 can be pulled out to reduce the overall number of lamp beads 201, reduce energy consumption, and increase its battery life. Embodiment 2
[0029] Such as Figure 10 and 11 shown, a dimming and color mixing method for a voltage-regulated light source module includes S1: The color temperature control module and the light intensity control module are connected in parallel in the circuit. A sliding rheostat is also connected in series on the color temperature switching module in the color temperature control module. The color temperature control module and the light intensity control module are connected in parallel in the circuit, so that the power supply voltages received by both are the same. The voltage of the color temperature control module remains unchanged, and the color temperature switching module and the sliding rheostat jointly use the voltage on the color temperature control module.
[0030] Each lamp bead 201 is connected in parallel in the circuit of the light source module. The contact switch 203 can be used as the on-off switch for controlling the lamp bead 201. The on-off switch inside the contact rod 301 and the temperature sensing rod 30 is connected in series with the circuit of the light source module on the same side, and can control the on-off of all the lamp beads 20 on one side.
[0031] S2: According to the control amount of the power supply voltage, the overall control voltage on the color temperature control module and the light intensity control module is controlled. The voltage is a variable voltage, and its voltage range varies from 12V to 24V. The light intensity control module is controlled by the power supply voltage, and the color temperature control module is controlled by a sliding rheostat.
[0032] S3: The power supply voltage acts on the electromagnet of the light intensity control module. According to the control amount of the power supply voltage, the magnetic force of the electromagnet is changed to adjust the light output of the light source module. The control amount of the power supply voltage acts on the electromagnet to control the magnetic force of the electromagnet, so that it adsorbs the magnet to generate displacement. The magnet can activate the corresponding number of lamp beads of the light source module, and the light output is controlled according to the number of lamp beads.
[0033] The change of the power supply voltage can directly control the magnetic property of the electromagnet 11. When it is 12V, the magnetic property of the electromagnet 11 is the smallest, and the magnetic force generated by its magnetism is much smaller than the pulling force of the stretching spring. Therefore, the magnetic slider 12 contacts the least number of on-off switches of the lamp beads 201, so the brightness is the lowest at this time, and vice versa. When the power supply voltage reaches 24V, the largest number of lamp beads 201 are started, so the brightness is the highest.
[0034] S4: The power supply voltage acts on the color temperature switching module and the sliding rheostat of the color temperature control module. By changing the resistance value on the sliding rheostat, the voltage on the color temperature switching module is adjusted to switch the color temperature.
[0035] A structure similar to a voltmeter is arranged inside the color temperature switching module 15 and is connected in parallel with the color temperature switching module 15 to measure the voltage of the resistance on the color temperature switching module 15. This voltage range is 5 - 10V, and the voltage adjustment range of the sliding rheostat is 2 - 16V. When the power supply voltage decreases, the sliding rheostat adjusts the resistance value so that the voltage on it decreases synchronously. At this time, the voltage on the color temperature switching module 15 can be kept unchanged to ensure that the color temperature remains unchanged. Or the resistance value on the sliding rheostat can be directly adjusted to adjust the voltage on the color temperature switching module 15, so that the voltmeter structure generates a mechanical rotation action, which can drive the gear 14 to rotate and switch the color temperature. The color temperature switching module and the sliding rheostat are connected in series, and the voltage on them is controlled according to the resistance size. By changing the resistance on the sliding rheostat, the voltage on it can be changed. By moving the sliding rheostat, the voltage on the color temperature switching module can be changed, so that it generates a mechanical displacement, thereby realizing the on-off of the light source and the switching of the color temperature of the light source.
[0036] Therefore, through this dimming and color mixing method combined with the above-mentioned light source circuit hardware, the light intensity and color temperature can be adjusted simultaneously under the same voltage power supply.
[0037] The above dimming and color temperature adjustment method realizes the synchronous adjustment of light intensity and color temperature by connecting the color temperature control module and the light intensity control module in parallel in the circuit. Specifically, a sliding rheostat is connected in series on the color temperature switching module in the color temperature control module. Users can control the color temperature and light intensity respectively by adjusting the power supply voltage and the resistance value of the sliding rheostat. Preferably, the power supply voltage range is 12V to 24V, which is applicable to common LED lighting modules. The working voltage of the electromagnet in the light intensity control module is recommended to be 5V to 24V. By adjusting the voltage magnitude, the number of magnetic sliders attracted is controlled, and then the number of lamp beads turned on is controlled to achieve multi-level brightness adjustment such as 20%, 50%, 100%, etc. The color temperature control module can realize the color temperature switching between 2700K and 6500K, and also supports stepped or continuous adjustment. Through the above structural and parameter settings, users can flexibly increase or decrease the number of light source modules according to actual needs, which can not only improve the lighting intensity but also extend the battery life, greatly enhancing the applicability and economy of the product.
[0038] The present invention also provides a temperature control switch inside the light source plug board for over-temperature protection. The temperature control switch includes components such as a temperature sensing rod, a shape memory alloy, and a reset spring. When the lamp beads work for a long time and the temperature rises to 85°C, the shape memory alloy deforms and contracts, driving the contact rod to disengage from the start switch, automatically turning off all the lamp beads on that side, and automatically restoring when the temperature drops below 70°C, preventing the lamp beads from being damaged due to overheating. This method effectively solves the technical problems of the existing light source module, such as a fixed number of lamp beads, a complex control system, and being easily damaged by temperature. Through the dimming and color temperature adjustment method combining mechanics and electricity, an efficient, stable, safe, and energy-saving lighting control effect is achieved, improving the reliability and service life of the system, reducing the maintenance cost, and having significant technological progress and application value.
[0039] In summary, for the voltage-regulated light source module and its dimming and color-tuning method, through the modularly arranged light source modules, they can be freely installed in the circuit board 10 to freely change the maximum intensity of the light source. The number of light source modules can be freely added or reduced according to the usage environment. That is, if high battery life is required, the number of light source modules can be reduced; if high illumination intensity is required, the number of light source modules needs to be increased, providing more choices for users. After the lamp beads 201 are used for a long time, the phenomenon of temperature rise will occur. When the temperature rises to a certain level, there is a possibility of damage to the lamp beads 201. Through the setting of the temperature-sensing rod 30, high temperature will cause the shape memory alloy 302 to deform and contract, compress the return spring 303, and drive the contact rod 301 to disengage from the start switch inside the temperature-sensing rod 30, turning off all the lamp beads 201 on this side until the temperature returns to normal and the contact rod 301 recontacts the start switch to turn on the lamp beads 201, thereby protecting the lamp beads 201 from being damaged due to excessive temperature. By applying a variable voltage to the electromagnet 11, the magnetic force intensity of the electromagnet 11 can be changed to attract the magnetic slider 12 to move. The number of contact switches 203 contacted by the displacement of the magnetic slider 12 is used to control the number of lamp beads 201 turned on, thereby controlling the intensity of the light source. Therefore, the light source module can dynamically control the light source intensity by the magnitude of the voltage. By changing the voltage, the color temperature switching module 15 drives the gear 14 to rotate, and then drives the contact slider 16 to slide through the switch ring 13, so that the contact slider 16 contacts or does not contact the two side secondary sockets 204 in the light source plug board 20 separately, thereby adjusting the cold and warm color temperatures and turning on and off of the light source. Cooperating with the light intensity control module, the change of color temperature can be realized. That is, when it is a cold color temperature, the intensity of the cold color is controlled by the number of lamp beads 201 turned on, realizing the adjustment of the color temperature intensity. Through such mechanical displacements, etc., the light intensity and color temperature are adjusted to make the adjustment process more stable.
