Abstract
The invention relates to a light-emitting diode (LED) lamp which comprises a connector, a heat dissipation ring, an LED chip, an LED driver and a bulb shade. The upper end of the heat dissipation ring is connected with the connector, the lower end of the heat dissipation ring is connected with the bulb shade, a base plate high in heat-conducting performance is installed inside the lower end of the heat dissipation ring, the LED driver is installed inside the heat dissipation ring, and the LED chip is installed on the bottom surface of the base plate. Compared with the prior art, the LED lamp has the advantages that the LED lamp is simple in structure and works stably, generated heat is less, heat is dissipated rapidly, and illumination is enhanced.
Description
Technical field
The present invention relates to lighting field, be specifically related to a kind of LED lamp.
Background technology
LED lamp has each function part conventionally, for example, comprise LED board, heat abstractor, driven unit, the camera lens of LED and circuit board, assembles, and the connection between these assemblies is complicated.LED chip heat radiation in LED lamp is very crucial, and too high temperature can cause LED lamp job insecurity, and the lost of life is only that cooling base dispels the heat in prior art.Therefore, be necessary to design a kind of thermal diffusivity good, LED lamp simple in structure.
Summary of the invention
Object of the present invention provide a kind of simple in structure, heat dispersion significantly promotes and LED lamp that can steady operation.
For addressing the above problem, the present invention adopts a kind of technical scheme: a kind of LED lamp is provided, comprise joint, heat dissipating ring, LED chip, LED driver and bulb shield, the upper end of described heat dissipating ring is connected with described joint, the lower end of described heat dissipating ring is connected with described bulb shield, the inner base plate that high thermal conductivity is installed in lower end of described heat dissipating ring, LED driver is installed in the inside of described heat dissipating ring, and described LED chip is installed on the bottom surface of base plate.
Further again, described a plurality of LED chips are connected successively, and one of them LED chip is connected with described LED driver.
Further again, described bulb shield is filled with heat-conducting gas, and heat-conducting gas is helium.
Further again, described LED chip is HVDC LED.
Further again, the bottom surface of described base plate arranges reflector layer.
Beneficial effect of the present invention: the situation of LED bulb shield heat dispersion deficiency in relative prior art, the present invention is except designing radiating bottom plate for LED chip, also in bulb shield upper end, install heat dissipating ring additional, dissipation of heat in bulb shield is gone out, in bulb shield, installed helium additional, accelerated distributing of chip output heat, by installing HVDC LED additional, compare low-voltage LED, under same power output, the required drive current of HVDC LED is significantly less than low-voltage LED, reduced LED dissipation of heat in the course of the work, this LED modulated structure is simple, good heat dissipation, working stability.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of LED lamp of the present invention.
In accompanying drawing, the list of parts of each label representative is as follows:
1, joint, 2, LED driver, 3, base plate, 4, LED chip, 5, bulb shield, 6, helium, 7, heat dissipating ring.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1: a kind of LED lamp, comprise joint 1, heat dissipating ring 7, LED chip 4, LED driver 2 and bulb shield 5, the upper end of described heat dissipating ring 7 is connected with described joint 1, the lower end of described heat dissipating ring 7 is connected with described bulb shield 5, the inner base plate 3 that high thermal conductivity is installed in lower end of described heat dissipating ring 7, LED driver 2 is installed in the inside of described heat dissipating ring 7, described LED chip 4 is installed on base plate 3, described a plurality of LED chip 4 is connected successively, one of them LED chip 4 is connected with described LED driver 2, described bulb shield 5 is filled with heat-conducting gas, heat-conducting gas is helium 6, described LED chip 4 is HVDC LED, described LED chip 4 is installed on the bottom surface of base plate 3.
LED lamp is when work, AC power in succession, electric current passes into LED driver 2 by circuit, AC power is transformed into the DC current of the steady that is applicable to LED chip 4, HVDC LED is luminous, because voltage height and the electric current of HVDC LED are little, caloric value also relatively existing LED lamp is a lot of less, in described bulb shield 5, be filled with helium 6, can avoid LED chip 4 oxidations, and helium 6 possesses good heat dispersion, can as early as possible heat be spread to surrounding, the heat that the base plate 3 of described high thermal conductivity also can produce LED chip 4 and LED driver 2 conducts out, and by described heat dissipating ring 7, dissipation of heat is gone out, and the reflector layer of base plate 3 can will be irradiated to light reflection on base plate 3 out, strengthened the intensity of illumination of LED lamp, relative prior art, the present invention can effectively reduce LED caloric value, accelerate dispersing of heat, make LED more stable work, life-span is stronger, and can strengthen intensity of illumination.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
