Abstract

The invention discloses a bulb-shaped LED lamp, which comprises a lamp cap, a bracket and an aluminous metal radiator. A substrate with an LED and a lamp cover are arranged on the top of the radiator; the radiator comprises an inner core inserted outside the bracket; and a plurality of vertical arc-shaped radiating fins are uniformly distributed outside the inner core along the same direction. The design effectively solves the attenuation problem of the LED and ensures operation of an LED lamp body close to normal temperature so as to ensure the durability of the entire lamp. Simultaneously, the LED lamp has the advantages of attractive appearance and practicability.

Description

A kind of bulb-shaped LED lamp
Technical field
The invention belongs to a kind of LED lamp, relate in particular to a kind of bulb-shaped LED lamp.
Background technology
Traditional lighting all adopts tungsten lamp or mercury fluorescent lamp, its shortcoming is that luminous efficiency is not high, and power consumption is big, service life is short, and not environmental protection, and the LED lamp is compared with conventional incandescent and fluorescent lamp, has advantages such as long, low in energy consumption, energy-conserving and environment-protective of life-span, and the LED lamp has obtained more and more widely use as lighting bulb.
Because LED is a photoelectric device, have only 15%~25% electric energy to convert luminous energy in its course of work, remaining electric energy nearly all converts heat energy to, the temperature of LED is raise, particularly the device core temperature of great power LED can rise rapidly, when temperature surpasses maximum allowable temperature, great power LED can damage because of overheated, therefore in the high-power LED lamp design, topmost design work is exactly a heat dissipation design, but the heat dissipation design of using on the existing product causes poor radiation at present, and the cost height is difficult to meet people's instructions for use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of bulb-shaped LED lamp of good heat dissipation effect.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of bulb-shaped LED lamp, it comprises lamp holder, support, aluminum metal radiator, described radiator top is equipped with substrate and the lampshade of band LED, described radiator comprises the inner core that is inserted into the support outside, and inner core is evenly distributed with several vertical arc fin that is provided with along same direction outward;
As improvement of the technical scheme, described radiator top is provided with the installing hole that is connected with substrate;
As further improvement in the technical proposal, described substrate is provided with 1 or above adopting surface mounted LED lamp body;
Further, described support is provided with the convex tendon that is used to shelve radiator;
Further, described support is provided with the installing hole that is connected with substrate;
Further, described lampshade bottom snaps onto on the substrate.
The invention has the beneficial effects as follows: the radiator in this product adopts the good aluminum metal of thermal conductivity to make and forms, thereby improved radiating efficiency to greatest extent, its top is connected with substrate in addition, the heat that the LED lamp body produces is delivered on the vertical arc fin of radiator naturally by substrate, because fin is along same direction setting, thereby the air-flow that produces a spiral makes air flow to increase radiating effect, this design effectively solves the attenuation problem of LED, guarantee that the LED lamp body is being tending towards carrying out work under the normal temperature, thereby guaranteed the durability of whole light fixture, simultaneously, product also has attractive in appearance, practical effect.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structure broken away view of the present invention;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a radiator vertical view of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of bulb-shaped LED lamp, it comprises lamp holder 1, support 2, aluminum metal radiator 3, radiator 3 is the aluminium section bar extrusion modling, described radiator 3 tops are equipped with substrate 4 and the lampshade 5 of band LED, described radiator 3 comprises the inner core 31 that is inserted into support 2 outsides, the inner core 31 outer vertical arc fin 32 that are evenly distributed with several along same direction setting.
This product is installed for convenience, and described radiator 3 tops are provided with the installing hole 33 that is connected with substrate 4; And described support 2 is provided with the installing hole 22 that is connected with substrate 4, and in addition, described support 2 is provided with the convex tendon 21 that is used to shelve radiator 3, and simultaneously, described lampshade 5 bottoms snap onto on the substrate 4.
In order to strengthen the luminous intensity of bulb, described substrate 4 is provided with 1 or above adopting surface mounted LED lamp body 41.
The radiating principle of this product is: the radiator 3 in this product adopts the good aluminum metal of thermal conductivity to make and forms, thereby improved radiating efficiency to greatest extent, its top is connected with substrate 4 in addition, the heat that LED lamp body 41 produces is delivered on the vertical arc fin 32 of radiator 3 naturally by substrate 4, because fin 32 is along same direction setting, thereby the air-flow that produces a spiral makes air flow to increase radiating effect, this design effectively solves the attenuation problem of LED, guarantee that LED lamp body 41 is being tending towards carrying out work under the normal temperature, thereby guaranteed the durability of whole light fixture, simultaneously, product also has attractive in appearance, practical effect.
