摘要： An industrial lighting device includes a driving module, a main light-emitting module and a top light-emitting module. The driving module has a top surface and a protrusion portion. The main light-emitting module is fixed at the protrusion portion. The top light-emitting module is disposed on the top surface, and includes a heat dissipation base, a top light source board and a top cover. The heat dissipation base is provided with a base body, an outer wall and a central fixation portion. The central fixation portion is disposed at the center of one side of the base body. The outer wall is disposed on the base body and surrounds the central fixation portion, such that an accommodating space is formed between them. The top light source board is disposed in the accommodating space and the top cover is disposed on the outer wall in order to cover the accommodating space.

摘要： A lighting device driving circuit with high operating efficiency is provided, which includes a rectifying module, a constant-voltage module, an input signal collecting module, a constant-voltage signal collecting module and a constant-voltage control module. The rectifying module receives a power signal from a power source input terminal to generate a rectified voltage signal. The constant-voltage module receives the rectified voltage signal to generate a constant-voltage signal. The input signal collecting module receives the power signal or the rectified voltage signal to generate a first feedback signal. The constant-voltage signal collecting module receives the first feedback signal and the constant-voltage signal to generate a second feedback signal. The constant-voltage control module generates a control signal according to the second feedback signal so as to control the constant-voltage module to adjust the constant-voltage signal and drive a load.

摘要： A dimmable light tube with anti-electric shock protection function includes two conductive pin assemblies, a bridge rectifier, an anti-electric shock detection control circuit, and a buck-boost constant current module. The bridge rectifier is connected to the conductive pin assemblies. The anti-electric shock detection control circuit is connected to the bridge rectifier, and the anti-electric shock detection control circuit has an output end and a resistor. The input end of the buck-boost constant current module is connected to the output end and the driving module is connected to the resistor so as to perform the leakage control function. The current conduction angle of the current generated by the transmission of the anti-electric shock detection control circuit can be changed by the buck-boost constant current module, so that the dimming function can be provided.

摘要： A polarity correction circuit for dimmer includes a control circuit, an adjustment circuit, and a detection circuit. The adjustment circuit is connected to the control circuit, a working voltage input end, and a dimmer, and the adjustment circuit includes several switches. The adjustment circuit receives a dimming signal of the dimmer. The detection circuit is connected to the dimmer and the control circuit, the detection circuit detects the dimming signal to generate a reference voltage, and the detection circuit transmits the reference voltage to the control circuit. The control circuit maintains the switch states of the switches of the adjustment circuit unchanged or adjust the switch states of the switches of the adjustment circuit according to the reference voltage.
