Description
Technical Field
The utility model belongs to the technical field of lighting source remote control, in particular to long-range components of a whole that can function independently controlling means of LED illumination.
Background
The remote control technology of the current LED illuminating lamp has been developed for many years, and mainly aims to solve the problems of remote LED illumination on, off, brightness adjustment, remote acquisition of current, voltage and other electrical parameter applications, so as to meet the application purposes of remote energy-saving control and illumination state detection of an illumination single lamp. At present, the lighting control modes are mainly as follows:
mode 1: an AC single lamp controller and LED dimming power supply approach is shown in fig. 3. The working principle is as follows: the AC single lamp controller is installed at the front end of the LED dimming power supply, the commercial power firstly passes through the single lamp controller and then passes through the LED dimming power supply, and the DC output end of the LED dimming power supply directly drives the LED light source module. The single lamp controller outputs dimming signals to the LED dimming power supply through the dimming lines, and the LED dimming power supply linearly transforms the LED driving current value according to the dimming signals, so that the purpose of controlling the illumination brightness is achieved.
This approach is not adequate: the AC single lamp controller needs to be installed at the forefront end of mains supply input, needs to be additionally provided with circuit modules such as an AC conversion DC power supply and mains supply surge protection, and is repeated with the LED dimming power supply part module, so that the cost of single lamp control of the illumination lamp is increased integrally. In addition, the method collects the Alternating Current (AC) current value and the voltage value of the power output end of the single lamp controller, but cannot collect the Direct Current (DC) current value and the voltage value output by the LED dimming power load, and when the LED light source is not bright or flickers due to the output fault of the LED dimming power, the fault misjudgment of the lighting lamp is often caused according to the sampling values of the AC voltage and the current.
Mode 2: digital communicator and LED digital power mode as shown in fig. 4. The working principle is as follows: the commercial power is supplied through the input end of the LED digital power supply, and the DC output end of the LED digital power supply directly drives the LED light source. The digital communicator is powered by an independent DC auxiliary source of the LED digital power supply and is connected with a serial port of the MCU singlechip of the LED digital power supply through the serial port of the MCU singlechip, so that bidirectional serial communication is realized.
Compared with the mode 1, the digital communicator is smaller than an AC single lamp controller, but the LED digital power supply is more complex to manufacture and poorer in temperature tolerance than an LED dimming power supply, and the system cost is equivalent.
The defects are as follows: if the LED digital power supply is applied to an LED lamp with a large power, the temperature in the work of the LED digital power supply is often higher than 90 ℃, the general temperature tolerance of the MCU singlechip arranged in the LED digital power supply is lower (generally highest 85 ℃), the MCU singlechip works in a high-temperature environment for a long time, the working stability is greatly reduced, and in order to ensure the stability, a more complex heat dissipation design is often required to be added, so that the manufacturing difficulty of the LED digital power supply is increased, and the manufacturing cost is also increased.
