Abstract: This application relates to the field of lighting, and discloses an LED filament. The LED filament includes an LED chip unit, a light conversion layer, and an electrode. The light conversion layer covers the LED chip unit and part of the electrode, and a color of a light emitted by the LED filament after lighting is different from a color of the light conversion layer. This application has the characteristics of uniform light emission and good heat dissipation effect.

Abstract: The present invention provides a lamp head assembly with positioning structures for combining with a lamp base. The lamp head assembly includes a conducting head and a supporting barrel. The conducting head has an insulating seat, a first conducting plate and a second conducting plate and a conduction piece. The conduction piece is electrically connected with the first conducting plate. A portion of the second conducting plate is protruded out of the insulating seat, and an end of the insulating seat is formed with a inserting plate. The supporting barrel includes a supporting section connected and an assembling section; wherein, the supporting barrel is assembled on the conducting head through a positioning of the inserting plate and the slot.

Abstract: The present invention provides an LED bulb and a lamp head structure hereof. The lamp head structure includes an insulating seat, a first conducting plate, a second conducting plate and a conducting piece. The insulating seat has a first accommodating space and a second accommodating space separately arranged and an opening slot communicating with the second accommodating space. The first conducting plate is accommodated in the first accommodating space. One end of the conducting piece inserted in the first conducting plate is electrically conducted with each other, and the other end is protruded out of the insulating seat. The insulating seats could be provided for different types of LED bulb. Thus the development time will be shortened, and the production cost will be reduced.
