Abstract

The utility model discloses an LED lamp with an excellent radiating effect. The LED lamp comprises a connector and a lamp body, wherein a plurality of LED components are installed on the lamp body; a light-transmission shade is sleeved on the lamp body outside an LED light source; the lamp body comprises radiating seat made of the mixture of graphite and plastics; the rear end of the radiating seat is connected with the connector; a plurality of radiating baseplates made of the mixture of the graphite and the plastics are extended from the front end of the radiating seat, are arranged in a ring and opened outwards; each LED component is installed on the outer side of each radiating baseplate, so as to allow the rays of the LED light source to be emitted out around the lamp body; and whereas the heat source parts of the LED components are connected with radiating baseplates, the light-emitting parts point outside the radiating baseplates. When the LED lamp is in use, the heat is firstly transferred to the radiating baseplates which are connected with the radiating seat where heat conducting and radiating are further carried out; and moreover, as the radiating effect of the graphite is better than that of aluminium alloy, the radiating effect is better with accelerated radiating.

Description

A kind of LED lamp with great heat radiation effect

Technical field

The utility model relates to the electricity-saving lamp field, refers in particular to a kind of LED lamp with great heat radiation effect.

Background technology

The LED lamp is the light fixture of new generation with many characteristics such as energy-saving and environmental protection, compares with present energy-saving daylight lamp, and under equal-wattage (W), brightness has increased several times, and its heat also increases a lot relatively.The heat of LED lamp must in time shed, and could guarantee its long-term normal use, and especially for high-power LED lamp, as it is untimely to dispel the heat, and with the light decay of accelerating the LED lamp, reduces service life.LED light fixture heat radiation commonly used at present is normal adopts aluminium alloy heat radiator, but its radiating effect is all not ideal enough, has influenced low-power LED lamp and has developed to miniaturization, then can influence the service life of high-powered LED lamp on the other hand.

In addition, in the more compact LED lamp of some structures is used, need on the peripheral side of a lamp body, be furnished with a plurality of LED; Its service life is shorter, and reason is: such as the LED candle lamp, because candle lamp is in a columned tiny scope, to need to arrange a plurality of led light sources; Be to be provided with back-to-back basically between the led light source individuality, its heat is difficult to leave more, therefore; The LED of this type uses not extensive, receives constraint to a certain degree.

Therefore in order to address the above problem, needing badly provides a kind of LED lamp with great heat radiation effect.

The utility model content

The utility model provides a kind of great heat radiation effect that has, rapid heat dissipation, the LED lamp of long service life.

The technical scheme of the utility model is:

A kind of LED lamp with great heat radiation effect comprises joint and lamp body, and a plurality of LED assemblies are installed on the lamp body; Be electrically connected between LED assembly and the joint; Be arranged with diffuser on the lamp body outside the led light source, said lamp body includes graphite plastic mixture radiating seat, the rear end jointing of graphite plastic mixture radiating seat; Front end is extended with multi-disc graphite plastic mixture heat-radiating substrate; Arrange circlewise between the graphite plastic mixture heat-radiating substrate and opening outside, the lateral surface of every graphite plastic hybrid heat-radiating substrate is separately installed with the LED assembly, and the light of led light source is penetrated around lamp body; The thermal source portion of LED assembly closely is connected with graphite plastic mixture heat-radiating substrate, and light direction points to diffuser.

Further, the lateral surface of said every graphite plastic hybrid heat-radiating substrate has the arc cavity respectively, and the LED assembly is installed in the arc cavity, makes the irradiate light better effects if.

In the said every graphite plastic hybrid heat-radiating substrate reflecting piece is arranged, reflecting piece is positioned at LED assembly rear, and irradiate light is good.

Further, have many longitudinal openings on the described diffuser, and corresponding with the gap between the adjacent graphite plastic mixture heat-radiating substrate, increase circulation of air, accelerate heat radiation.

Further, be formed with vertical heat radiation inner chamber between the graphite plastic mixture heat-radiating substrate, avoid gathering of heat.

In addition, preferably, described diffuser is translucent cover or diffusion shell, decides according to the needs that use.

In addition, the arc inner chamber of each said graphite plastic mixture heat-radiating substrate is to be made up of a flank dull and stereotyped and that be located at said dull and stereotyped both sides, and said LED substrate is fixed on the flat board between two flanks.

Wherein, the graphite plastic radiator that is formed in one of graphite plastic mixture radiating seat and graphite plastic mixture heat-radiating substrate.

Said graphite plastic mixture heat-radiating substrate and LED assembly have corresponding four or more than, evenly distribute, circumferentially be provided with.

A kind of LED lamp that the utility model provides with great heat radiation effect; When the LED lamp dispels the heat, its heat will at first be delivered on the graphite plastic mixture heat-radiating substrate, because graphite plastic mixture heat-radiating substrate is connected with graphite plastic mixture radiating seat; Can further carry out heat conduction and heat radiation; And the thermal diffusivity of graphite is with respect to the radiating effect of aluminium alloy, so its radiating rate is faster, better heat-radiation effect; Graphite plastic mixture lamp socket also can be accelerated heat radiation simultaneously, guarantees better heat radiating effect.
