Abstract
The invention provides an LED lamp of a double-layer radiating plate. The LED lamp comprises a bowl-shaped shell (1), a lamp base (8), a radiating basal plate (4), a plurality of LEDs (7), an upper-layer radiating plate (2) and a plurality of heat conducting blocks, wherein the lamp base is fixed on the top part of shell; the radiating basal plate has a shape of a circular plate; the LEDs are uniformly fixed on the lower surface of the radiating basal plate; the shell is provided with a plurality of radiating holes (9); the upper-layer radiating plate has a shape of a circular plate, and the edge of the upper-layer radiating plate is fixed on a protruding block (11) on the inner wall of the shell; and the heat conducting blocks are fixed below the upper-layer radiating plate, and the upper-layer radiating plate is fixed below the heat conducting blocks. Because the LED lamp of the invention has the double-layer radiating plate structure formed by the radiating basal plate and the upper-layer radiating plate, partial heat generated by the LEDs is transferred to the upper-layer radiating plate from the radiating basal plate by the heat conducting blocks, and then dissipated by the cooperation of the radiating basal plate and the upper-layer radiating plate, so that the radiating area is enlarged and the radiating capability of the LED lamp is greatly improved.
Description
Technical field
The present invention relates to a kind of structure of LED lamp, a kind of LED lamp that double-deck heat sink is arranged.
Background technology
The LED lamp adopts a plurality of high brightness LEDs to make light source, has that luminous efficiency height, power consumption are few, the advantage of long service life, is widely used in the apparatus of places such as market, factory, office, school, hospital as illumination.The heat dispersion of LED lamp is the key factor that influences its luminous efficiency and life-span.People all do effort on the heat dispersion that improves the LED lamp.For example, Chinese patent application 200710164533.3 discloses a kind of structure of high-powered LED lamp, is provided with the heat sink with its disjunctor around the lamp body, utilizes heat sink to increase heat-sinking capability.
Summary of the invention
The present invention is intended to propose a kind of new construction of LED lamp, and a kind of LED lamp that double-deck heat sink is arranged can obtain better radiating effect.
This LED lamp that double-deck heat sink arranged comprises shell, lamp holder, heat-radiating substrate and several light emitting diodes of bowl-type.Lamp holder is fixed on the top of shell, and heat-radiating substrate is a circular plate type, and light emitting diode is fixed on the lower surface of heat-radiating substrate equably, and several louvres are arranged on the shell.This have the LED lamp of double-deck heat sink also to comprise upper strata heat sink and several piece heat-conducting block.The upper strata heat sink is a circular plate type, and the edge of upper strata heat sink is fixed on the projection of outer casing inner wall, and heat-conducting block is fixed on the below of upper strata heat sink, and heat-radiating substrate is fixed on the below of heat-conducting block.
This have the LED lamp of double-deck heat sink owing to adopted heat-radiating substrate and this double-deck cooling plate structure of upper strata heat sink, some is sent to the heat that light emitting diode produces on the heat sink of upper strata from heat-radiating substrate by heat-conducting block, dispel the heat by heat-radiating substrate and upper strata heat sink cooperation, increased area of dissipation, the heat-sinking capability of LED lamp is strengthened.

The specific embodiment
As shown in Figure 1, this LED lamp that double-deck heat sink arranged comprises shell 1, lamp holder 8, heat-radiating substrate 4, several light emitting diodes 7, upper strata heat sink 2 and the several piece heat-conducting block 3 of bowl-type.Heat-radiating substrate is a circular plate type, and the upper strata heat sink also is a circular plate type, and lamp holder is fixed on the top of shell, and light emitting diode is fixed on the lower surface of heat-radiating substrate equably.As shown in figures 1 and 3, several louvres 9 are arranged on the shell 1.The edge of upper strata heat sink 2 is fixed on the projection 11 of inwall of shell 1, and heat-conducting block 3 is fixed on the below of upper strata heat sink, and heat-radiating substrate 4 is fixed on the below of heat-conducting block.Electronic drive is placed in the cavity of the top of upper strata heat sink 2 in the shell 1.
The heat part that light emitting diode 7 produces is dispersed in the ambient air by heat-radiating substrate 4, and another part is sent on the upper strata heat sink 2 by heat-conducting block 3, is distributed by the upper strata heat sink again.Louvre 9 on the shell 1 can make the air and extraneous exchange in the shell, increases radiating effect.Also reduced simultaneously the operating temperature of electronic drive.
This shell that the LED lamp employing bowl-type of double-deck heat sink is arranged, the shape of lamp is easy to match with various light fixtures, is attached on the conventional spirality lamp socket, and it is comparatively convenient to use.
As Fig. 1, Fig. 4 and shown in Figure 5, the middle part of the upper strata heat sink 2 in this LED lamp that double-deck heat sink arranged can also have several to discharge orifice 6, and the air that can increase lamp inside flows, and improves radiating effect.
Shown in Figure 2 as Fig. 1, a plurality of breeder tubes 10 that can also distribute on the heat-radiating substrate 4 in this LED lamp that double-deck heat sink arranged, and, as shown in Figure 5, the gap 12 of a circle ventilation is arranged between the outer rim of heat-radiating substrate 4 and the shell 1.Such structure, light emitting diode 7 and heat-radiating substrate ambient air can be by the breeder tube on the heat-radiating substrate 10, heat-radiating substrate outer rim and the gap between the gap between the shell 12, heat-radiating substrate 4 and the upper strata heat sink 2, upper strata heat sink on the louvre on discharge orifice 6 and the shell 9 is flowed, make the inside and outside air of lamp realize convection current, increased the radiating effect of LED lamp greatly.
Heat-radiating substrate 4, upper strata heat sink 2 and heat-conducting block 3 in this LED lamp that double-deck heat sink arranged generally can be made of the good metal of thermal conductivity, for example, make of copper or aluminium, can obtain better heat radiating effect.
