Abstract: A cabinet light includes a light emitting element, a light housing, conductive terminals, a cabinet body, and conductive rails. The light emitting element and the conductive terminals are fixed on the light housing. The conductive rails are fixed on the cabinet body. One end of the conductive terminal is electrically connected to the light emitting element. At least one positioning element is disposed on the cabinet body corresponding to the light housing. When the light housing is fixed on the cabinet body through the positioning element, the other end of the conductive terminal is elastically and electrically connected to the conductive rail. The cabinet body has advantages of simple wiring and use flexibility.

Abstract: A bulb apparatus includes a driver plate and a bulb head body. The bulb head body is a housing structure with top opening. The sidewall of the bulb head body forms a first electrode terminal. The bottom of the driver plate is placed inside the bulb head body. The bulb apparatus also includes a connection base and a first electrode. The connection base is fixed on the driver plate. The connection base has an embedding trench. The first electrode has a fixing end electrically connected to the driver plate via the embedding trench and a connecting end elastically abutting on the inner sidewall of the first electrode terminal.

Abstract: An LED driver circuit includes a rectifying module, a control unit, and at least two LED light strings. The control unit includes a voltage input detection terminal and a switch assembly. The voltage input detection terminal is configured to detect the waveform of the voltage input. The switch assembly changes the way of connection between the LED light strings according to the waveform of the voltage input.
