Be provided with trumpet-shaped reflector in the described container cavity.

Described reflector adopts nanometer reflective energy-saving sheet.

Described radiating seat is provided with fixed support.

The top of described radiating seat is provided with light-passing board.

Described radiating fin is the shaped form structure.

Described radiating fin is camber line shape, spiral yarn shaped or involute shape structure.

The height that described radiating fin stretches to the top along the radiating seat bottom increases progressively.

Evenly form plurality of grooves on the described light source board end face, led light source is embedded in the groove.

The utility model beneficial effect is:

The LED energy-conserving barrel lamp that the utility model provides, it comprises lamp holder, light source board, radiating seat, power-supply controller of electric, the bottom of lamp holder is installed in the power-supply controller of electric, lamp holder is fixed on the bottom of radiating seat, radiating seat is horn-like structure, the lateral surface of radiating seat forms a plurality of radiating fins, the radiation shape that a plurality of radiating fins are rounded, the top of radiating seat offers container cavity, light source board closely is arranged in the container cavity, be embedded with a plurality of led light sources on the light source board, the utility model be on light source board fixedly encapsulated LED light source as lighting source, and be equipped with special radiating seat and improve radiating effect, the radiating fin of circle out shape increases the area of dissipation of radiating seat, when the led light source operating illumination, the heat that led light source produced is through behind the light source board, reach radiating seat, in time promptly distribute by radiating fin again, thereby improve the radiating effect of LED energy-conserving barrel lamp, avoid shorten the light decay of the led light source that slows down the service life of led light source, compare with traditional lighting source, the utility model can be saved a large amount of power supplys, and is easy to recycle, and belongs to green, environment-friendly products.
