Embodiment 1

[0041] Such as figure 2 As shown, a HID electronic ballast online tester mainly detects the constant power control part in the DC-AC conversion circuit, including the main body of the tester and the test circuit 1 arranged on the main body of the tester. The test circuit 1 mainly includes an oscilloscope 10. Programmable controller 12, amplification / comparison circuit 11, dummy load 13 four parts.

[0042] Oscilloscope 10 is used to detect the output Ga and the waveform of Gb of the circuit on the constant power control board 2 under test; overlap or true.

[0043] The programmable controller 12 controls the entire detection process by the program of the programmable controller. The input end of the programmable controller 12 is provided with a program start button 121, and is also provided with a positive error out-of-tolerance signal I01 and a negative error out-of-tolerance signal I02; The output end of the programmable controller 12 is provided with an output execution ...

Abstract

The invention relates to electronic ballast production on-line testing equipment, in particular to an HID (high intensity discharge) electronic ballast on-line tester which mainly tests constant power control portion in an electronic ballast DC-AC (direct current-alternating current) conversion circuit. The specific technical scheme includes that the HID electronic ballast on-line tester comprises a tester body and a test circuit arranged on the tester body and is characterized in that the test circuit comprises an oscilloscope, a programmable controller, an amplifying / comparison circuit and a dummy load, the oscilloscope is used for testing waveforms of output Ga and Gb of a circuit on a tested constant power control panel, the programmable controller comprises a program starting button, a positive error out-of-tolerance signal I01, a negative error out-of-tolerance signal I02 and an output executing relay J which are positioned at an input end, the amplifying / comparison circuit comprises a current amplifying portion and a comparator COMP, the dummy load is formed by connecting a capacitor with a resistor and used for substituting for a bulb portion on the tested constant power control panel.

Description

technical field [0001] The invention relates to production and testing equipment for electronic ballasts, in particular to a HID electronic ballast online tester, which mainly detects the constant power control part in the DC-AC conversion circuit of the electronic ballast. Background technique [0002] HID electronic ballasts have been widely used. However, in the process of mass production, the quality control mainly depends on the final inspection. The pass rate of the final inspection depends on: 1. Strict control of the incoming inspection of components, and the consistency control of technical parameters must also be achieved; 2. There is no error in the installation of components; 3. There is no false welding in welding; 4. The production process If there is an abnormality in the final inspection, it will increase the difficulty of fault inspection during repair, affect the efficiency, and even damage multiple components. The repair work must be done by professional...
