Description

Technical Field

[0001] This utility model relates to the field of DOB light source control technology, specifically an energy-saving multi-color temperature DOB light source control device. Background Technology

[0002] In the current lighting technology field, DOB light sources, with their advantages of high integration of driving circuits and light source chips, compact structure, small footprint, and low production cost, have been widely used in various scenarios such as home lighting, commercial lighting, and industrial lighting, becoming an important part of LED lighting products. As people's demands for lighting quality continue to rise, single-color-temperature lighting products can no longer meet the needs of diverse scenarios. For example, in home environments, users need warm color temperatures to create a cozy atmosphere when relaxing, while cool color temperatures are needed to ensure visual clarity when working or studying. Commercial venues such as clothing stores and supermarkets also need to adjust the color temperature to highlight the texture of goods and enhance the shopping experience.

[0003] However, traditional DOB light sources are mostly designed with a single color temperature, which cannot adapt to the lighting needs of different scenarios. For example, in home spaces, bright cool white light is needed for daily activities to ensure clear vision, while soft warm white light is needed to create a cozy atmosphere when relaxing. A single color temperature light source cannot meet the diverse needs. Some DOB light sources that attempt to achieve multi-color temperature adjustment have complex control circuit designs and require additional redundant components, resulting in a significant increase in energy consumption and low energy utilization. This does not meet the current development trend of energy conservation and environmental protection and the "dual carbon" target requirements. Therefore, we propose an energy-saving multi-color temperature DOB light source control device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an energy-saving multi-color-temperature DOB light source control device. This device offers energy-saving advantages and solves the problem that traditional DOB light sources are mostly designed with a single color temperature, making them unsuitable for different lighting needs in various scenarios. For example, in home spaces, bright cool white light is needed for daily activities to ensure clear vision, while soft warm white light is needed for relaxation to create a cozy atmosphere. Single-color-temperature light sources cannot meet these diverse needs. Furthermore, some DOB light sources that attempt to achieve multi-color-temperature adjustment suffer from complex control circuit designs, requiring additional redundant components, leading to significantly increased energy consumption and low energy utilization, which does not conform to the current trend of energy conservation and environmental protection and the "dual-carbon" target requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving multi-color temperature (DOB) light source control device, comprising a lampshade, a partition fixedly connected to the inner wall of the lampshade, a first DOB light source module and a second DOB light source module fixedly connected to the bottom of the partition, an infrared sensor and a light intensity sensor fixedly connected to the left and right sides of the bottom of the lampshade respectively, a DOB light source controller disposed on the top of the partition, a power supply module, a color temperature adjustment module and a current detection module fixedly connected sequentially from left to right on the rear side of the bottom of the inner cavity of the DOB light source controller, and an EMC filter, a processor and an overcurrent protection unit fixedly connected sequentially from left to right at the middle of the bottom of the inner cavity of the DOB light source controller.

[0006] Preferably, a frame is fixedly connected to the rear side of the top of the partition, and springs are fixedly connected to both sides of the inner cavity of the frame. An adjusting rod is fixedly connected to one side of the spring, and a pin is inserted into the inner cavity of the adjusting rod. One side of the pin is fixedly connected to the DOB light source controller, and one side of the adjusting rod contacts a baffle. A movable door is fixedly connected to the top of the baffle. One side of the movable door is movably connected to the lampshade via a hinge, and a lock body is provided on the other side of the movable door.

[0007] Preferably, the DOB light source controller has an insertion hole on the front, the lampshade has a movable groove on the bottom, and a light guide plate is fixedly connected to the inner cavity of the movable groove.

[0008] Preferably, a support frame is fixedly connected to the bottom of the outer surface of the lampshade, and a movable groove is provided on the front of the frame.

[0009] Preferably, the inner cavity of the adjusting rod is slidably connected to a prism, and both sides of the prism are fixedly connected to the frame.

[0010] Preferably, a frame is inserted into the bottom of the surface of the DOB light source controller, and the bottom of the frame is fixedly connected to the partition.

[0011] Compared with the prior art, this utility model provides an energy-saving multi-color temperature (DB) light source control device, which has the following beneficial effects: 1. After the device is started, external AC power is first connected to the power module. After rectification, filtering, and voltage regulation within the power module, it is converted into DC power. Simultaneously, the EMC filter is activated to filter electromagnetic interference signals from the power grid, avoiding interference with the operational stability of core components such as the processor and color temperature adjustment module. This provides a clean and stable power supply environment for the entire device, reducing energy consumption and signal interference risks at the source. The device is equipped with an infrared sensor and a light intensity sensor to collect environmental data in real time: the infrared sensor can detect whether there is human activity in the space; if there is no human signal for a long time, a low-power mode is triggered; the light intensity sensor monitors the ambient natural light intensity, converts the light intensity data into an electrical signal, and transmits it to the processor. In addition, the current detection module continuously collects data from the first DOB light source module and the second DOB light source module. The operating current signal of the source module provides real-time feedback on the operating status of the light source, providing data support for subsequent adjustment and protection. If the user issues a command through an external controller, the processor sends a control command to the color temperature adjustment module. The color temperature adjustment module outputs PWM signals with different duty cycles according to the command, controlling the brightness of the first DOB light source module and the second DOB light source module respectively. By changing the brightness ratio of the two light sources, continuous and smooth switching of color temperature is achieved to meet the lighting needs of different scenarios. Energy-saving control logic: When the infrared sensor detects that no one is in the space for more than a preset time, or the light intensity sensor detects that the ambient light intensity is higher than a preset threshold, the processor automatically reduces the power output to reduce ineffective energy consumption. If human activity is detected or the ambient light intensity is insufficient, normal lighting power is quickly restored, taking into account both energy saving and ease of use.

[0012] 2. When the DOB light source controller needs to be repaired, the lock of the movable door is opened, the movable door rotates around the hinge and drives the baffle to move. After the baffle is disengaged from the adjusting rod, the adjusting rod is moved to both sides to separate the adjusting rod from the pin, so that the DOB light source controller can be easily taken out for maintenance. After maintenance is completed, the operation is reversed to make the pin re-engage, ensuring that the DOB light source controller is fixed and stable, and does not affect the signal transmission and power supply continuity of the internal modules.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an energy-saving multi-color temperature DOB light source control device, including a lampshade 1. A partition 2 is fixedly connected to the inner wall of the lampshade 1.

A DOB light source controller 7 is provided on the top of the partition 2. A power module 10, a color temperature adjustment module 11, and a current detection module 12 are fixedly connected from left to right to the rear side of the bottom of the inner cavity of the DOB light source controller 7. An EMC filter 13, a processor 9, and an overcurrent protection unit 14 are fixedly connected from left to right to the middle of the bottom of the inner cavity of the DOB light source controller 7. A socket 8 is provided on the front of the DOB light source controller 7. A movable groove is provided on the bottom of the lampshade 1, and a light guide plate is fixedly connected to the inner cavity of the movable groove.

[0018] The specific functions of this technical solution are as follows: After the device is started, external AC power is first connected to the power module 10. After rectification, filtering, and voltage regulation within the power module 10, it is converted into DC power. Simultaneously, the EMC filter 13 is activated to filter electromagnetic interference signals in the power grid, avoiding interference with the operational stability of core components such as the processor 9 and color temperature adjustment module 11. This provides a clean and stable power supply environment for the entire device, reducing energy consumption and signal interference risks at the source. The infrared sensor 5 and light intensity sensor 6 on the device collect environmental data in real time: the infrared sensor 5 can detect whether there is human activity in the space. If there is no human signal for a long time, a low-power mode is triggered; the light intensity sensor 6 monitors the ambient natural light intensity and converts the light intensity data into an electrical signal for transmission to the processor 9. In addition, the current detection module 12 continuously collects data from the first DOB light source module 3. The operating current signal of the second DOB light source module 4 provides real-time feedback on the operating status of the light source, providing data support for subsequent adjustment and protection. If the user issues a command through an external controller, the processor 9 sends a control command to the color temperature adjustment module 11. The color temperature adjustment module 11 outputs PWM signals with different duty cycles according to the command, controlling the brightness of the first DOB light source module 3 and the second DOB light source module 4 respectively. By changing the brightness ratio of the two light sources, the color temperature can be continuously and smoothly switched to meet the lighting needs of different scenarios. Energy-saving control logic: When the infrared sensor 5 detects that no one is in the space for more than a preset time, or the light intensity sensor 6 detects that the ambient light intensity is higher than a preset threshold, the processor 9 automatically reduces the power output to reduce ineffective energy consumption. If human activity or insufficient ambient light intensity is detected, the normal lighting power is quickly restored, taking into account both energy saving and ease of use. Example 2:

[0019] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3 As shown, a frame 17 is fixedly connected to the rear side of the top of the partition 2. Springs 18 are fixedly connected to both sides of the inner cavity of the frame 17. An adjusting rod 19 is fixedly connected to one side of the spring 18. A pin 16 is inserted into the inner cavity of the adjusting rod 19. One side of the pin 16 is fixedly connected to the DOB light source controller 7. One side of the adjusting rod 19 contacts a baffle 20. A movable door 21 is fixedly connected to the top of the baffle 20. One side of the movable door 21 is movably connected to the lampshade 1 via a hinge. A lock body 22 is provided on the other side of the movable door 21. A support frame 23 is fixedly connected to the bottom of the outer surface of the lampshade 1. A movable groove is opened on the front of the frame 17. A prism is slidably connected to the inner cavity of the adjusting rod 19, and both sides of the prism are fixedly connected to the frame 17. A frame 15 is inserted into the bottom of the surface of the DOB light source controller 7. The bottom of the frame 15 is fixedly connected to the partition 2.

[0020] The specific function of this technical solution is as follows: When the DOB light source controller 7 needs to be repaired, the lock body 22 of the movable door 21 is opened. The movable door 21 rotates around the hinge and drives the baffle 20 to move. After the baffle 20 disengages from the adjusting rod 19, the adjusting rod 19 is moved to both sides to separate the adjusting rod 19 from the pin 16, so that the DOB light source controller 7 can be easily taken out for maintenance. After maintenance is completed, the operation is reversed to make the pin 16 re-engage, ensuring that the DOB light source controller 7 is fixed and stable, and does not affect the signal transmission and power supply continuity of the internal modules.

[0021] Working Principle: After the device starts, external AC power is first connected to the power module 10. After rectification, filtering, and voltage regulation within the power module 10, it is converted into DC power. Simultaneously, the EMC filter 13 starts to filter electromagnetic interference signals in the power grid, avoiding interference with the operation stability of core components such as the processor 9 and color temperature adjustment module 11. This provides a clean and stable power supply environment for the entire device, reducing energy consumption and signal interference risks from the source. The infrared sensor 5 and light intensity sensor 6 on the device collect environmental data in real time: the infrared sensor 5 can detect whether there is human activity in the space. If there is no human signal for a long time, a low-power mode is triggered; the light intensity sensor 6 monitors the ambient natural light intensity, converts the light intensity data into an electrical signal, and transmits it to the processor 9. In addition, the current detection module 12 continuously collects data from the first DOB light source module 3 and the second DOB light source module 11. The operating current signal of the OB light source module 4 provides real-time feedback on the operating status of the light source, providing data support for subsequent adjustment and protection. If the user issues a command through an external controller, the processor 9 sends a control command to the color temperature adjustment module 11. The color temperature adjustment module 11 outputs PWM signals with different duty cycles according to the command, controlling the brightness of the first DOB light source module 3 and the second DOB light source module 4 respectively. By changing the brightness ratio of the two light sources, the color temperature can be continuously and smoothly switched to meet the lighting needs of different scenarios. Energy-saving control logic: When the infrared sensor 5 detects that no one is in the space for more than a preset time, or the light intensity sensor 6 detects that the ambient light intensity is higher than a preset threshold, the processor 9 automatically reduces the power output to reduce ineffective energy consumption. If human activity or insufficient ambient light intensity is detected, the normal lighting power is quickly restored, taking into account both energy saving and ease of use. When the DOB light source controller 7 needs to be repaired, open the lock body 22 of the movable door 21. The movable door 21 rotates around the hinge and drives the baffle 20 to move. After the baffle 20 disengages from the adjusting rod 19, move the adjusting rod 19 to both sides to separate the adjusting rod 19 from the pin 16. The DOB light source controller 7 can then be easily removed for maintenance. After maintenance, reverse the operation to make the pin 16 re-engage, ensuring that the DOB light source controller 7 is fixed and stable, and does not affect the signal transmission and power supply continuity of the internal modules.
