Problems solved by technology

[0007] In other words, conventional dimmers cannot be used in large buildings, government agencies, apartments, parking lots, factories and other places that require central control. They are only used individually for LED lights, which is very inconvenient and cannot be effectively managed.
[0008] In addition, since central control cannot be performed at all, there is a problem that appropriate measures cannot be taken when problems occur due to large current radiation or leakage of LED lamps.

Embodiment 1

[0070] Such as figure 1 As shown, the remote control high-power dimming system 100 for LED lamps according to an embodiment of the present invention may include a server 110, a gateway 120, a motion sensor 130, a local controller 140, a high-power automatic dimmer 150, and LED lamps 160 interconnected and communicate with each other.

[0071] The server 110 in the high-power dimming system 100 can remotely control the dimming system of multiple LED lamps 160, and can self-perceive data such as ambient temperature, ambient illuminance, overcurrent, etc., and perform dimming control or cut off the current. The advantage is that one high-power automatic dimmer 150 can control multiple LED lamps 160 without installing dimmers in the LED lamps, or installing additional equipment or additional construction on the original LED lamps. In addition, the server 110 can be notified in time by detecting faults caused by overcurrent, so that the LED lights 160 of large buildings, governmen...

Embodiment 2

[0080] On the basis of the above examples, if figure 2 As shown, the high-power automatic dimmer 150 includes a wireless module 151 , a temperature sensor 152 , an illumination sensor 153 , a current sensor 154 , a CPU 155 , a MOSFET module 156 and a filter 157 interconnected and communicated with each other. The specific configuration will be described below.

[0081] The wireless module 151 is used for wirelessly receiving dimming control signals from the local controller 140 . The wireless module 151 is composed of wireless methods such as zigbee, bluetooth, and Wi-Fi.

[0082] The temperature sensor 152 is used to sense the ambient temperature. It is also used for LED dimming control according to the ambient temperature. Moreover, when the temperature peak is exceeded, it can be used to prevent malfunction or error by taking measures such as cutting off power in real time. A temperature peak value is preset in the temperature sensor 152 .

[0083] The illuminance sen...

[0095] image 3 The circuit shown in FIG. 1 is an example of the circuit of the high-power automatic dimmer 150, and various configurations can be made differently from it. Figure 4 It is a flowchart of a remote control high-power dimming method for LED lamps according to an embodiment of the present invention.

[0096] On the basis of the above examples, if Figure 3-Figure 4 As shown, step S101: the server 110 generates and sends a dimming control signal.

[0097] Step S102: the gateway 120 receives the dimming control signal from the server 110, and sends it by means of RS485 communication.

[0098] Step S103 : the local controller 140 receives the dimming control signal from the gateway 120 .

[0099] Step S104: The motion sensor 130 senses the peripheral motion, and sends the motion signal to the local controller 140 through zigbee or bluetooth communication.

[0100] Step S105: When the local controller 140 receives the motion signal from the motion sensor 130, it w...

Abstract

The invention discloses a remote control high-power dimming system and method for LED lamps. The remote control high-power dimming system and method for the LED lamps comprises a server, a gateway, a motion sensor, a local controller, a high-power automatic dimmer and a plurality of LED lamps, wherein the server is used for generating and sending a dimming control signal, the gateway is used for receiving the dimming control signal from the server and sending the dimming control signal, the motion sensor is used for sensing surrounding motion and sending a motion signal, the local controller is used for receiving the dimming control signal from the gateway and sending the dimming control signal, the high-power automatic dimmer is used for receiving the dimming control signal in a wireless mode from the local controller and conducting dimming control, and the plurality of LED lamps are used for conducting display according the dimming control of the high-power automatic dimmer. Due to the adoption of the technical scheme, the high-power LED lamps can be controlled in a remote mode, the dimming control or current cutting off can be conducted according to data, such as temperature data, illumination data and excess current data, sensed by the LED lamps, and therefore an effect of conveniently and smoothly starting and managing the plurality of LED lamps is achieved in a remote mode.

Description

technical field [0001] The present invention relates to an LED high-power dimming system and method, and more specifically, to a high-power dimming system and method for remotely controlling a plurality of LED lamps. Background technique [0002] The original dimmer is used to precisely control the illuminance of lighting such as fluorescent lamps or LED lamps, which not only wastes power, but also cannot prevent safety accidents before they happen. [0003] However, as far as the original LED lamp is concerned, since the dimmer is connected to the ballast output end of each LED lamp to control the dimming, it is necessary to install another dimmer on each LED lamp. At this time, one dimmer can only dim and control one LED lamp. That is, there is a problem that a plurality of LED lamps cannot be controlled by one dimmer. [0004] On the other hand, conventional LED lamps use ballasts with built-in SMPS (switching mode power supply, switching mode power supply), which has t...
