Abstract

The utility model discloses a finned LED (light-emitting diode) lamp and relates to the technical field of LED lamps. The finned LED lamp comprises a lamp cap and a drive power supply module, wherein an aluminum alloy circular tube is vertically arranged on the upper side of the lamp cap; a plurality of arc heat dissipation fins are uniformly arranged on an outer side wall of the circular tube in a diffused manner; the inner ends of the heat dissipation fins are fixed on the outer side wall of the circular tube; the outer ends of the heat dissipation fins are arc; the lower end faces of the heat dissipation fins are fit with the upper side of the lamp cap; the top ends of the heat dissipation fins and the top end of the circular tube are located in the same plane; every three adjacent heat dissipation fins are in a group and jointly jack up and fix a horn-shaped micro lamp housing with an opening facing outwards by taking the middle heat dissipation fin as a center; the heat dissipation fins on the outer sides are overlapped between the groups; the lamp housings are internally provided with LED lamp beads; and the drive power supply module is fixed in the circular tube. The finned LED lamp has a good heat dissipation effect, the heat dissipation fins can lead heat emitted by the LED lamp beads in the lamp housings out rapidly, the lamp housings emit light simultaneously, so that the brightness is high, and the LED lamp is reasonable in structure.

Description

Fin-type LED lamp

Technical field

The utility model relates to a kind of LED lamp technical field.

Background technology

The advantages such as that LED light fixture has is energy-conservation, long service life, gradually replacing incandescent lamp and fluorescent lamp becomes the main flow trend in market, still, along with the power of LED lamp manufacture increasing, it is bad and affect the lamp problem in service life that part LED lamp also exists heat radiation.

Summary of the invention

For overcome current LED lamp power manufacture increasing, it is bad and affect the lamp problem in service life that part LED lamp also exists heat radiation, the utility model provides a kind of fin-type LED lamp, this fin-type LED lamp good heat dissipation effect, radiating fin can be derived rapidly the heat that in lamp housing, LED lamp distributes, luminosity is high, rational in infrastructure simultaneously for multiple lamp housings.

The technical solution of the utility model is, a kind of fin-type LED lamp, comprise lamp holder, driving power module, the upside of lamp holder is vertically provided with tube and pipe of aluminium alloy, the lateral wall divergence form of pipe is evenly provided with multiple arc radiating fins, the inner of radiating fin is fixed on the lateral wall of pipe, the outer end of radiating fin is arc, the lower surface of radiating fin and the laminating of lamp holder upside, the top of radiating fin and pipe top are at same plane, three adjacent radiating fins are one group, centered by central radiating fin, common picking-up fixed an opening horn-like midget lamp housing outwardly, between each group, there is the radiating fin in an outside overlapped, in each lamp housing, be provided with LED lamp pearl, in pipe, be fixed with driving power module, the power output end of driving power module is by wire and the electrical connection of each LED lamp pearl, the power input electrical connection of lamp holder and driving power module.

The position of the midget lamp housing in described each group of adjacent radiating fin outside is crisscross arranged up and down, and the madial wall of midget lamp housing is coated with reflecting coating.

Described radiating fin is 15, and the upper end of tube and pipe of aluminium alloy is provided with seal closure.

Owing to adopting said structure, this fin-type LED lamp good heat dissipation effect, radiating fin can be derived rapidly the heat that in lamp housing, LED lamp distributes, and luminosity is high, rational in infrastructure simultaneously for multiple lamp housings.
