一种LED灯具调控系统An LED lamp control system

技术领域technical field

本实用新型涉及一种电源设备，特别是一种信号调控的LED灯具调控系统。The utility model relates to a power supply device, in particular to a signal-controlled LED lamp control system.

背景技术Background technique

随着“人性化照明”的理念深入人心，照明设计应营造良好的室内照明效果，以满足人们生理、心理等各方面的要求。现在越来越多的灯光设计中使用LED灯具，同时LED灯具也开始替代原有的普通灯具，如日光灯、卤素灯，荧光灯等。普通灯具的电源一般只有正负两根电源线，当用LED灯具替换这些普通灯具时，用于给LED灯具提供电力的正负两根电源线可以使用原有的电源线，但是当要调控LED灯具的亮度或色温时，则需要增加另外的信号线，这些信号线也至少需要两根，而对于一些LED灯具的大型使用场合，LED灯具的增多，所需要的不同的亮度或色温的增多，将使得信号线的使用量大增，从而增加了LED灯具的成本与布线的施工量，进而不利于灯具的总体成本的控制。With the concept of "humanized lighting" deeply rooted in the hearts of the people, lighting design should create a good indoor lighting effect to meet people's physiological and psychological requirements. Now more and more LED lamps are used in lighting design, and LED lamps are also beginning to replace the original ordinary lamps, such as fluorescent lamps, halogen lamps, fluorescent lamps, etc. The power supply of ordinary lamps generally only has two positive and negative power cords. When replacing these ordinary lamps with LED lamps, the positive and negative two power cords used to provide power to LED lamps can use the original power cords, but when it is necessary to control the LED When the brightness or color temperature of the lamp is increased, additional signal lines need to be added, and at least two of these signal lines are required. For some large-scale use occasions of LED lamps, the increase of LED lamps requires an increase of different brightness or color temperature. It will greatly increase the usage of signal wires, thereby increasing the cost of LED lamps and the amount of wiring construction, which is not conducive to the control of the overall cost of lamps.

实用新型内容Utility model content

有鉴于此，有必要提供一种可以减少输电及控制线路的LED灯具调控系统，以克服上述不足。In view of this, it is necessary to provide an LED lighting control system that can reduce power transmission and control lines, so as to overcome the above-mentioned shortcomings.

The signal detection control module is used to output a signal for regulating the parameters of the LED lamp according to the output signal of the signal separation module.

与现有技术相比，所述LED灯具调控系统首先将控制信号耦合到LED驱动电源的输出电压中，当该输出电压给LED灯具提供电源之前，再利用信号分离模块与信号检测控制模块对该控制信号进行分离、编译，然后提供给为LED灯具，从而可以使得仅用两根导线便可以实现所述LED灯具的亮度或色温等参数的控制，进而实现了连接导线数量的减小，以及有利于降低成本与排版难度的特点。Compared with the prior art, the LED lamp control system first couples the control signal to the output voltage of the LED drive power supply, and before the output voltage provides power to the LED lamp, the signal separation module and the signal detection control module are used to control the output voltage of the LED lamp. The control signal is separated, compiled, and then provided to the LED lamp, so that the brightness or color temperature of the LED lamp can be controlled with only two wires, thereby reducing the number of connecting wires and effectively It is beneficial to reduce the cost and typesetting difficulty.

Of course, it is conceivable that thesignal generation module 11 may also include a programmable processor, which generates various control signals according to the user's programming and compiling to generate the user's desired effect. In this embodiment, thesignal generating module 11 is a remote controller, and therefore, the signal generatingmodule 11 does not appear in the circuit diagram of the LEDlamp control system 100 shown in FIG. 2 . When the signal generatingmodule 11 is a programmable processor, it can be set in the real object of the LEDdriving power supply 10 .

所述信号接收耦合模块12用于接收来自信号产生模块11的控制信号，并将该控制信号耦合到LED驱动电源10的输出电压中。根据信号产生模块11的结构及工作原理，该信号接收耦合模块12具有相对应的结构及工作原理，如当信号产生模块11包括遥控器时，该信号接收耦合模块12应具有一个遥感接收元器件，而当信号产生模块11为一种可编译的处理单元，该信号接收耦合模块12具有与处理单元相对应的信号接收单元。总之，所述信号接收耦合模块12应具有与信号产生模块11相对应的信号接收单元。耦合是指信号从前一级传输到后一级采用的传输方式，其为一种现有习知技术，完成该耦合的元器件、电路、及模块皆为本领域技术人员所习知的技术，再此不作赘述。为了便于将控制信号耦合到所述LED驱动电源10的输出电压中，所述信号接收耦合模块12设置在该LED驱动电源10的实物中，而未在图2的电路图中标出。The signal receiving andcoupling module 12 is used for receiving the control signal from thesignal generating module 11 and coupling the control signal into the output voltage of the LEDdriving power supply 10 . According to the structure and working principle of thesignal generating module 11, the signal receivingcoupling module 12 has a corresponding structure and working principle, such as when the signal generatingmodule 11 includes a remote controller, the signal receivingcoupling module 12 should have a remote sensing receiving component , and when the signal generatingmodule 11 is a compilable processing unit, the signal receivingcoupling module 12 has a signal receiving unit corresponding to the processing unit.

The circuit shown in FIG. 3 includes a diode D1, a diode D1 connected in series A capacitor C1, and a transistor Q2 connected in series with the capacitor C1. In order to divide the voltage of thesignal separation module 13 and limit the current to avoid damage to components, at least one current limiting resistor R1, R4 is also included.

The transistor Q2 is an NPN type, its base is electrically connected to the capacitor C1 , its collector is electrically connected to the signaldetection control module 14 , and its emitter is grounded. Thesignal separation module 13 formed by this circuit can separate the control signal coupled to the output voltage of the LEDdriving power supply 10 and transmit it to the signaldetection control module 14 . In order to prevent thesignal separation module 13 from being reversely connected to the circuit, thesignal separation module 13 also includes an anti-reverse device. The anti-reverse device is used to prevent the positive and negative poles of thesignal separation module 13 from being electrically connected to the positive and negative poles of the LED driving power supply in reverse. In this embodiment, the anti-reverse device 131 is a diode D2.

The signaldetection control module 14 first needs to detect the signal from thesignal separation module 13, and then the signaldetection control module 14 compiles the signal, and then outputs the processed signal, that is, the DC/DC module 16 can identify Signal. As for the specific processing procedure of the signaldetection control module 14, it should be known to those skilled in the art, and will not be described in detail here. When the signaldetection control module 14 is a single-chip microcomputer, it needs a suitable power supply.

Here, when the switch is turned off, the electric energy is released to the load to provide energy. Its output power or voltage capability is related to the duty cycle (the ratio of the switch conduction time to the entire switch cycle). The DC/DC module 16 can be used for step-up and step-down. In the present invention, the DC/DC module 16 will output a current whose amplitude is constant but whose width is modulated by the signaldetection control module 14 to drive the load LED lamp. When the signaldetection control module 14 adjusts the magnitude of the current, the DC/DC module 16 will control the magnitude of the input current of the LED lamp according to the output control signal of the signaldetection control module 14, thereby controlling the brightness or parameters such as color temperature.
