A light bulb holder structure includes a bulb cap and a connector. By integral molding, the connector made of insulating material is molded with one end of the bulb cap to form an integration. The protrusion on the connector can increase the creepage distance of the light bulb, so as to improve waterproof performance of the light bulb and suppress erosion caused by ingress of water. In addition, the bulb cap may further be provided with connection parts to secure the combination of the connector and the bulb cap. Further, the end portion of the connector close to bulb cap may be provided with a threaded segment, and the threaded segment is an optional structure which can not only greatly improve the creepage distance, but also fix the relative position of the connector and the bulb cap when the light bulb is screwed into the socket.

A modular LED lamp system allows for stacking multiple LED carriers to provide the desired amount of light. Each LED carrier preferably includes its own transformer to convert line voltage to power useable by the LEDs on the carrier. Line voltage is conducted through each module to a subsequent module and is provided to the transformer.

An assembly includes a contact interface device, a lamp base and a circuit board. This device is connected to the circuit board and is used to bias the circuit board within the center of a cavity of a light bulb. This device contains two or more biasing portions that are connected to one another through a bridge portion. The biasing portions engage an interior threaded portion of the lamp base in order to lock into place and not allow the circuit board to move. The bridge portion allows the biasing portions to counteract one another and suspend the circuit board in the middle of the cavity of the light bulb.

A high-insulation integrated plastic lamp holder that does not require traditional American and European-standard copper lamp holders, comprising a high-insulation plastic body formed by injection molding. The top of the high-insulation plastic body is provided with a barrier, a first conductive component slot, and a second conductive component slot, and the barrier is located between the first conductive component slot and the second conductive component slot. The first conductive component slot and the second conductive component slot are inserted into positive and negative conductive sheets correspondingly, and the assembly of the lamp holder is simpler, which facilitates automatic production, thereby greatly improving the daily production capacity and insulation, and lowering the cost of production.
