Abstract

Disclosed is a light-emitting diode (LED) lamp bulb capable of enhancing heat dissipation. The LED lamp bulb capable of enhancing the heat dissipation comprises a lamp head, an insulating shell connected with the front end of the lamp head, and an aluminum heat dissipating frame body connected with the front end of the insulating shell, wherein the front end of the aluminum heat dissipating frame body is connected with an aluminum substrate, the front end of the aluminum heat dissipating frame body is also connected with a lamp shade for covering the aluminum substrate. Besides, the aluminum heat dissipating frame body comprises a hollow body and a cooling fin arranged on the hollow body, wherein a drive power module is installed inside the aluminum heat dissipating frame body. An LED light emitting unit is arranged on the aluminum substrate, the lamp head is in electric connection with the drive power module. The drive power module is in electric connection with the aluminum substrate. A side wall of the hollow body of the aluminum heat dissipating frame body is provided with a hollowed-out part. The LED lamp bulb capable of enhancing the heat dissipation has the advantages that the hollowed-out part is formed on the hollow body of the aluminum heat dissipating frame body by removal of materials, and therefore the heat dissipation effect is improved.

Description

A kind of LED bulb of enhance heat
(1) technical field
The utility model relates to a kind of LED bulb.
(2) background technology
The LED bulb adopts the LED luminescence unit to replace the heating wire in the incandescent light modulation on the traditional sense, thus the effect of the energy saving that has realized.
But the caloric value of LED luminescence unit and driving power module is all very large, and we generally adopt aluminium base and aluminium radiating frame to be used for heat radiation, and the aluminium radiating frame comprises a hollow body and the fin of being located on the hollow body.
(3) summary of the invention
In order to overcome the deficiency of existing LED bulb heat radiation poor-performing, the utility model provides a kind of LED bulb of enhance heat.
The technical scheme in the invention for solving the technical problem is: a kind of LED bulb of enhance heat, comprise a lamp holder, be connected in the insulation shell of lamp base front end, be connected in the aluminium radiating frame of insulation shell front end, described aluminium radiating frame front end is connected with aluminium base, described aluminium radiating frame front end also is connected with lampshade described aluminium base cover, described aluminium radiating frame comprises a hollow body and the fin of being located on the hollow body, be provided with the driving power module in the described aluminium radiating frame, described aluminium base is provided with the LED luminescence unit, described lamp holder is electrically connected the driving power module, described driving power module is electrically connected aluminium base, offers hollow-out parts on the limit wall of the hollow body of described aluminium radiating frame.
Described hollow body is a hollow pipe, and the one end has and expands end.
Also comprise following additional technical feature: one is used for the fixedly excessively thread fixing plate of electric connection line.
Be positioned at the driving power module of hollow body so that thereby extraneous air-flow directly enters directly to cool off in the hollow body by hollow-out parts on the described hollow-out parts, and also increased the throughput on the fin of flowing through, increased radiating efficiency.
The utility model is consistent with the LED bulb of prior art in use, does not repeat them here.
The beneficial effects of the utility model are: remove material at the hollow body of aluminium radiating frame and be formed with hollow-out parts, thereby increased the efficient of dispelling the heat.
(4) description of drawings
Fig. 1 is the schematic diagram of an embodiment of the utility model.
Fig. 2 is the explosive view of another embodiment of the utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
By reference to the accompanying drawings 1 and 2, a kind of LED bulb of enhance heat, comprise a lamp holder 1, be connected in the insulation shell 2 of lamp base front end, be connected in the aluminium radiating frame 3 of insulation shell front end, described aluminium radiating frame front end is connected with aluminium base 4, described aluminium radiating frame front end also is connected with lampshade 5 described aluminium base 4 covers, described aluminium radiating frame 3 comprises a hollow body 3A and the fin 3B that is located on the hollow body 3A, be provided with driving power module 6 in the described aluminium radiating frame, described aluminium base 4 is provided with the LED luminescence unit, described lamp holder 1 is electrically connected driving power module 6, described driving power module 6 is electrically connected aluminium base 4, offers hollow-out parts 3C on the limit wall of the hollow body 3A of described aluminium radiating frame 3.
Described hollow body is a hollow pipe, and the one end has to expand holds 3D.
Also be provided with one between described driving power module 6 and the aluminium base 4 and be used for the fixedly excessively thread fixing plate 7 of electric connection line.
Be positioned at the driving power module 6 of hollow body so that thereby extraneous air-flow directly enters directly to cool off in the hollow body by hollow-out parts on the described hollow-out parts, and also increased the throughput on the fin of flowing through, increased radiating efficiency.
The present embodiment is consistent with the LED bulb of prior art in use, does not repeat them here.
The present embodiment is removed material at the hollow body of aluminium radiating frame and is formed with hollow-out parts 3C, thereby has increased the efficient of heat radiation.
