Description

[0001] The present application relates to the technical field of lighting equipment, and in particular to an LED color temperature adjustment device and a lamp. Background Art

[0002] Currently, most lamps on the market can adjust the color temperature. If users want to achieve different color temperatures according to different atmospheres, they need to adjust the LED to the desired color temperature in a step-by-step order. For example, a lamp has three color temperatures, and the default color temperature is cold light, and there is a color temperature sequence: cold light, neutral light, and warm light. When the user wants warm light, they need to adjust the cold light to neutral light, and then from neutral light to warm light. In other words, the color temperature adjustment of warm light can only be completed in a step-by-step order, which is time-consuming. Secondly, some lamps are installed on the ceiling, and auxiliary tools such as ladders are required for adjustment, which is inconvenient. Thirdly, the color temperature is monotonous, for example, only cold light, neutral light, or warm light can be achieved. Technical issues

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] Please refer to Figure 1, which is a structural block diagram of an LED color temperature adjustment device in an embodiment of the present application. The LED color temperature adjustment device 00 shown in Figure 1 includes: a first control module 20, a second control module 30, a first LED driving module 40 and a first adjustment switch 10, wherein the first adjustment switch 10 includes a plurality of gears, and each gear corresponds to a different color temperature, wherein each gear can correspond to a color temperature (for example, gear 1: 2000k, gear 2: 3000k...), or can correspond to a color temperature combination, and the color temperature combination can include more than two color temperatures (for example, gear 1: 2000k and 5000k, gear 2: 3000k and 6000k...), which is not limited here; wherein, the first adjustment switch includes but is not limited to a push switch, a touch switch and an M-speed dial switch, etc., which can realize a multi-speed adjustment switch, and the first adjustment The adjustment switch can be at least one of a push switch, a touch switch and an M-speed dial switch, wherein when the first adjustment switch is a dial switch, M is the number of gears, which can be 2 to 9, that is, the adjustment range of the first adjustment switch can be freely selected from 2 to 9 gears. The first adjustment switch 10 is a push switch or a touch switch, which can reflect different color temperatures through different pressing methods, touch methods or operating forces, and the color temperature corresponding to each gear is set by default at the factory. Subsequent users can also customize the color temperature values ​​of each gear according to their own different usage habits and needs, giving the color temperature adjustment greater freedom and more personalization. Among them, the first control module 20, the second control module 30, and the first LED driver module 40 can be control chips with control and data processing capabilities such as single-chip microcomputers, MCUs, FPGAs, etc., and this application does not make specific limitations by giving examples here.

[0051] The output end of the first adjustment switch 10 is connected to the input end of the first control module. The first adjustment switch 10 is used to receive a gear closing operation by the user and output a gear position signal corresponding to the gear closing operation to the first control module 20. It can be understood that the gear closing operation is generated by the user operating the switch. If the user closes the switch, it means that the gear closing operation has been performed. At this time, the LED will be illuminated according to the target color temperature corresponding to the target gear position. Conversely, if the user opens the switch, it means that the gear opening operation has been performed. At this time, the LED will be extinguished. When the user closes the switch, it means that the gear opening operation has been performed. When the user closes the switch, it means that the gear closing operation has been performed. For example, if Shift 1 is 2000K, Shift 2 is 3000K, etc., closing Shift 1 will make the LED emit a color temperature of 2000K, and closing Shift 1 and Shift 2 will make the LED emit a color temperature of 2000K and 3000K. Of course, for example, if Shift 1 is 2000K and 5000K, and Shift 2 is 3000K and 6000K, closing Shift 1 will make the LED emit a color temperature of 2000K and 5000K, and closing Shift 1 and Shift 2 will make the LED emit a color temperature of 2000K, 5000K, 3000K, and 6000K. This enriches the color temperature range.

[0052] The output end of the first control module 20 is electrically connected to the input end of the second control module 30 and the input end of the first LED driver module 40, respectively. The first control module 20 is used to receive the gear position signal, output the first control signal to the first LED driver module 40, and output the color temperature adjustment signal to the second control module 30. It should be noted that the first control module serves as the main control of the adjustment device. The first control module can be a single-chip microcomputer, which is used to detect the gear position signal and simultaneously output the color temperature adjustment signal and the first control signal, wherein the color temperature adjustment signal is a PWM signal corresponding to the color temperature, and the first control signal is a light control signal. The adjustment device can also have a memory function, which can remember the historical color temperature last adjusted. The first control module will obtain the color temperature adjustment signal more quickly based on this historical color temperature and the target color temperature.

[0053] The output end of the first LED driving module 40 is used to be electrically connected to the first LED 50. The first LED driving module 40 is used to receive the first control signal and output the first driving signal to the first LED 50. The first LED driving module can drive the LED with a constant current, which is not limited here.

[0054] The output end of the second control module 30 is used to be electrically connected to the first LED 50, and the second control module 30 is used to receive the color temperature adjustment signal and output the target color temperature signal to the first LED; it should be noted that the second control module 30 is a color temperature control IC, which adjusts the duty cycle of the input PWM signal to control the LED color temperature.

[0055] The first LED 50 is used to receive the first drive signal and the target color temperature signal, so that the first LED lights up and emits the target color temperature corresponding to the target gear. It should be noted that the types of LEDs include but are not limited to all types of lamps such as LED bulbs and fan lights.

[0056] Exemplarily, the first adjustment switch is a 9-speed dial switch, and gear positions 1 to 9 correspond to color temperatures of 1:2000K,..., color temperature 9:5000K, respectively; the user then turns the paddle corresponding to gear position 1 to close the switch, and the target color temperature is the color temperature 1 corresponding to gear position 1. Then the first LED lights up and emits the color temperature 1:2000K corresponding to gear position 1.

[0057] Furthermore, the first LED may include N LEDs, and the N LEDs may be connected in parallel, in series, or in series-parallel, which is not limited here, and N≥2; then each gear may correspond to a different combination of color temperatures, for example, gear 1 corresponds to 2000k and 5000k.

[0058] At this time, the first LED is also used to receive the first driving signal and the target color temperature signal, so that the N LEDs are lit and combined to emit the target combined color temperature corresponding to the target gear position.

[0059] Exemplarily, the first adjustment switch is a 9-position DIP switch, where N is 2, i.e., two LED combinations, positions 1 to 9, correspond to color temperatures 1: 2000k and 5000k, ..., and 9: 2700k and 5000k, respectively. The user then toggles the paddle corresponding to position 1 to close the switch. At this point, the target color temperature is color temperature 1, corresponding to position 1. The first LED then lights up and emits color temperatures 1: 2000k and 5000k, corresponding to position 1. One LED in the combination emits 2000k, and the other emits 5000k. At this point, the second control module 30 adjusts the luminous ratio of the two LED light sources by adjusting the duty cycle of the input PWM signal, thereby achieving the purpose of color adjustment. The output currents of the two parallel LEDs complement each other, and the total current remains unchanged during the color adjustment process, equal to the current of the constant current source.

[0060] Furthermore, users can also dial multiple gears, such as closing gear 1 and gear 2. If the color temperature of gear 1 is 2000K and the color temperature of gear 2 is 5000K, the target color temperature emitted by the LED can be the color temperature of 2000K and 5000K selected by the user. If the color temperature of gear 1 is 2000K and 5000K, and the color temperature of gear 2 is 2000K and 9000K, the target color temperature emitted by the LED can be the combined color temperature of 2000K and 5000K and 2000K and 9000K. This can further provide users with more color temperature combinations, allowing users to customize the color temperature they want based on their own needs, which is more flexible and personalized.

Furthermore, the color temperature of each gear can be a single color temperature value or a combination of multiple color temperature values. The user's gear closing operation can close a single gear or multiple gears, making the LED color temperature more diverse.

For details, please refer to the contents of the first regulating switch 10, the first control module 20, the second control module 30, the first LED driver module 40 and the first LED 50 shown in Figure 1.

[0066] Furthermore, the output end of the rectifier module 90 is electrically connected to the power supply end of the first LED driver module 40, the power supply end of the second LED driver module 60, the power supply end of the first control module 20, the power supply end of the second control module 30, and the power supply end of the switch signal detection module 80, respectively. The input end of the rectifier module is connected to the mains power. The rectifier module 90 is used to output a power supply signal to power the first LED driver module, the second LED driver module, the first control module, the second control module, and the switch signal detection module.

[0067] The output end of the switch signal detection module 80 is electrically connected to the input end of the first control module 20. The switch signal detection module is used to output the on-off signal of the main switch to the first control module. The first control module is also used to receive the on-off signal and the gear signal, output the first control signal to the first LED driver module and the second LED driver module, and output the color temperature adjustment signal to the second control module; exemplarily, the first control module 20 serves as the main control microcontroller, which is used to detect the wall control signal and the switch gear signal, and at the same time output the PWM signal corresponding to the color temperature and the main night light control signal. The wall control signal is also the on-off signal. The main switch is a wall-mounted switch, and the first adjustment switch is a switch on the lamp. The on / off signal is used to reflect the on / off status of the main switch. The switch signal detection module serves as the wall-mounted switch signal detection circuit. When the wall-mounted switch is in the closed state, DZ1 outputs a high level, and when the wall-mounted switch is in the open state, DZ1 outputs a low level. The on / off signal can be a high or low level signal to reflect the on / off status of the main switch. When the on / off signal is high, it indicates that the power is on, and the first main control module can adjust the color temperature according to the user's color temperature adjustment operation. Conversely, when the on / off signal is low, it indicates that the power is off, and the first main control module will not respond to the user's adjustment operation, but will adjust the color temperature. Color temperature adjustment is performed in the form of a dual switch. In addition, if after the main switch is closed, if no color temperature adjustment operation is received from the user within the preset time, the LED color temperature can be adjusted directly based on the last color temperature selection, that is, the adjustment device has a memory function. When the main switch is closed and no color temperature adjustment operation is received from the user within the preset time, such as when an unexpected power outage occurs and then restored, or when the user does not make a new color temperature selection after closing the switch, the LED color temperature can be adjusted according to the historical color temperature selection. This saves user operations and makes the adjustment device shown in this application more capable of responding to unexpected situations. The preset time can be 2S, 3S, etc., and is not limited here. Taking the preset time of 2S as an example, when the main switch is closed for more than 2s and no color temperature adjustment operation is detected, the LED color temperature will be adjusted according to the color temperature selection of the last color temperature adjustment operation.

[0068] Among them, in order to facilitate the adjustment of color temperature, a wireless remote control module can also be set. The wireless remote control module is electrically connected to the input end of the first control module and can be optionally used to receive infrared remote control signals, wireless radio frequency signals, WIFI signals, Bluetooth signals, Zigbee signals, etc., so the closing operation can also be issued in the form of remote control to adjust the color temperature.

[0069] The input end of the second LED driver module 60 is electrically connected to the output end of the first control module. The output end of the second LED driver module is used to electrically connect to the second LED. The second LED driver module 60 is used to receive the first control signal and output the second drive signal to the second LED. The second LED is used to receive the second drive signal to light up the second LED. The second LED can be a night light, and the second LED driver module can be a driver IC for the night light, which can be an MCU, FPGA, or single-chip microcomputer or other control devices. That is, the night light can be turned on while the first LED is closed. It should be noted that the second LED can also be an LED with adjustable color temperature. In this way, the color temperature range can be further enriched by matching the second LED. In this way, the second LED can also adjust its own color temperature as needed when used as a night light.

[0070] The output of the power regulation module 100 is electrically connected to the input of the first LED driver module. The power regulation module 100 is configured to receive power adjustment commands from the user and output a power adjustment signal to the first LED driver module. For example, the power regulation module 100 can be used to adjust the LED power by operating another switch to disconnect a fixed resistor to change the drive current (drive signal) of the first driver module.
