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.

摘要： A working light includes a frame and a plurality of LED modules located in the frame. Two supporting plates at two ends of the frame are respectively combined with two ratchets. Two ends of the LED modules are combined with ratchet plates. The ratchets are respectively assembled to the ratchet plates to control a rotation angle of the LED modules. The working lights can be stacked with each other in one or more directions. The ratchets are at the side portions of the LED module. Therefore, after the LED module is assembled in the frame of the working light, the ratchets allow the LED module to be rotatable within 180 degrees. Hence, the LED module can be rotated, so that the illumination angle of the LED module is adjustable.

摘要： A protection system for a lamp is provided. One or more control circuit boards and one or more thermal devices are disposed in the lamp. The control circuit board has an electrical circuit. The thermal device is disposed on the control circuit board and connected to the electrical circuit. The thermal device is attached to one or more thermal fuses with a binding member. Accordingly, the safety of the driving power supply can be increased. Moreover, the thermal fuse not only provides protection for the inputs of the driving power supply, but also provides protection for other main or branch circuits.
