Detailed Description
The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
the utility model provides a lighting system based on wireless control. As shown in fig. 1, the wireless control based lighting system includes: the LED lamp comprises at least two light emitting modules, a light source module and a light source module, wherein the light emitting modules comprise at least two light emitting circuits with different color temperatures, and each light emitting circuit comprises at least one light emitting component; the input end of the AC-DC constant voltage module is connected with the power output ends L and N, and the output end of the AC-DC constant voltage module is connected with the light-emitting circuit; the input end of the DC-DC voltage reduction circuit is connected with the output end of the AC-DC constant voltage module; the input end of the wireless communication module is connected with the first output end of the DC-DC voltage reduction circuit; the intelligent terminal is in communication connection with the wireless communication module and is used for controlling the wireless communication module to output different control signals; the input end of the switch circuit is connected with the second output end of the DC-DC voltage reduction circuit and the output end of the wireless communication module, and the output end of the switch circuit is connected with one path of light-emitting circuit in each light-emitting module and used for controlling the light-emitting circuit according to different control signals output by the wireless communication module.
In order to realize the adjustment of color temperature and brightness, the light emitting module comprises at least two paths of light emitting circuits with different color temperatures, and each path of light emitting circuit can comprise one light emitting component or a plurality of light emitting components connected in series. In this embodiment, the light emitting assembly employs LED lamps, and the color temperatures of the LED lamps in each path are different. When the color temperature and the brightness of the light emitting module need to be adjusted, the light emitting circuit needs to be controlled to be turned on or off.
Compared with alternating current power supply, the light-emitting assembly is more stable and safer under the condition of direct current power supply. Meanwhile, in order to prevent the light emitting device from operating at an unstable voltage, it is necessary to operate at a stable and safe voltage. In this embodiment, an AC-DC constant voltage module is connected to an output terminal of the power supply. The AC-DC constant voltage module is an LLC topological isolating switch power supply, can convert alternating current output by the power supply into direct current, and can control voltage output within a safe voltage range. The AC-DC constant voltage module outputs voltage to supply power to the light emitting module and the wireless communication module.
Since the operating voltage of the wireless communication module and the switching circuit is lower than that of the light emitting module, it is necessary to step down the voltage output from the AC-DC constant voltage module. In this embodiment, a DC-DC step-down circuit is connected to the output terminal of the AC-DC constant voltage module. The DC-DC voltage reduction circuit is a buck topology non-isolated voltage reduction circuit and converts the voltage output by the AC-DC constant voltage module into a voltage suitable for the wireless communication module and the switch circuit.
the wireless communication module is a module capable of wirelessly and remotely transmitting information data, and may be generally zigbee, bluetooth, or the like. The module can output two or more paths of PWM control signals.
The intelligent terminal can be intelligent equipment such as a smart phone and a computer, can be communicated with the wireless communication module and is used for controlling the wireless communication module to output a corresponding PWM control signal, and therefore remote light modulation and color temperature modulation are finally achieved.
And the switch circuit is used for controlling the connected light-emitting circuit. The light emitting circuit is connected with the light emitting circuit with the same color temperature in each light emitting module, and when the light emitting circuit with the color temperature needs to be turned off, the switch circuit connected with the light emitting circuit needs to be controlled to be turned off, so that the principle of turning on the light emitting circuit with the color temperature is also the same. Therefore, the multi-path light-emitting circuits can be controlled in a centralized manner by only controlling one switching circuit, the on or off of the multi-path light-emitting circuits connected with the switching circuit is synchronously controlled, and the light-adjusting and color-temperature-adjusting consistency is realized.
Specifically, as shown in fig. 2, the switching circuit includes MOS transistors Q1, Q3, a transistor Q2, resistors R2, R3, R5, and R6, a base of the transistor Q2 is connected to the wireless communication module, a collector of the transistor Q2 is connected to one end of the resistor R2, one end of the resistor R5, and a gate of the MOS transistor Q3, an emitter of the transistor Q2 is grounded, the other end of the resistor R2 is connected to the DC-DC step-down circuit, the other end of the resistor R5 is grounded, a drain of the transistor Q3 is connected to one end of the resistor R3, one end of the resistor R6, and a gate of the MOS transistor Q1, a source of the MOS transistor 3 is grounded, the other end of the resistor R3 is connected to the DC-DC step-down circuit, the other end of the resistor R6 is grounded, a source of the MOS transistor Q3 is grounded, and a drain of the transistor Q3.
Since the PWM control signal from the wireless communication module cannot directly drive the main power MOS transistor Q1, the main power MOS transistor Q1 needs to be further driven by adding the small current MOS transistor Q3, and the transistor Q2 has the same phase, i.e., when the transistor Q2 is turned on, the MOS transistor Q1 is also turned on, and when the transistor Q2 is turned off, the MOS transistor Q1 is also turned off.
the specific working principle of the switching circuit is as follows: when the PWM control signal sent by the wireless communication module is at a high level, the transistor Q2 is turned on, the MOS transistor Q3 is turned off, and the MOS transistor Q1 is driven to be turned on by the VCC5V power supply through the voltage division of the resistor R3 and the resistor R6, that is, the switch circuit is turned on. On the contrary, when the PWM control signal sent by the wireless communication module is at a low level, the transistor Q2 is turned off, the MOS transistor Q3 turns on the gate of the MOS transistor and is grounded through Q3, and the MOS transistor Q1 is turned off, that is, the switching circuit is turned off, so that the on or off of the switching circuit is controlled by the PWM control signal.
In order to increase the working stability of the light-emitting circuit, the light-emitting circuit comprises a constant current module which is connected with the light-emitting component in series, and the input end of the constant current module is connected with a corresponding switch circuit. The constant current module is used for controlling the current of the light emitting circuit within a certain range.
Specifically, as shown in fig. 3, the constant current module includes a low dropout regulator U1 and a resistor R1, a first pin of the low dropout regulator U1 is connected to the light emitting device, a second pin of the low dropout regulator U1 is connected to one end of the resistor R1, and the other end of the resistor R1 is connected to a third pin of the low dropout regulator U1 and the switch circuit.
The U1 is a low dropout regulator, and when the voltage across the resistor R1 exceeds the design voltage of the regulator, the regulator operates to reduce the current flowing through the R1, thereby reducing the current flowing through the light-emitting circuit. The voltage drop of the light-emitting circuit is reduced along with the reduction of the current, and the current of the light-emitting circuit is increased along with the reduction of the voltage drop due to the constant-voltage power supply, so that the current is constant in a fixed range.
In actual operation, a single resistor R1 may generate heat seriously due to large power consumption, in this embodiment, the resistor R4 is added, the resistor R4 is connected in parallel with the resistor R1, and the power consumption of the resistor R1 is reduced by adding the resistor R4.
Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
