Abstract

The utility model relates to a novel flat shell LED lighting lamp, which comprises a flat plate transparent cover, at least a high power LED, a circuit board, a heat dissipation plate, and a metal shell. The flat plate transparent cover is adopted in the lamp cover to replace the traditional round lamp cover, thus the structure and the process are simpler, and the light is more fully dissipated. A voltage transforming and rectifying device is arranged on the circuit board. By replacing the light source such as an incandescent lamp, a fluorescent lamp, etc. with a high power LED lamp, the utility model has the advantages of being durable, long life, being more environmental protection, etc. The heat dissipation plate compactly contacts with the metal shell, thus a heat dissipation system with better heat dissipation effect is formed, the heat dissipation is more fully, and the high power LED can be ensured normally working in a suitable temperature.

Description

A kind of novel flat shell LED illuminating lamp

Technical field

The utility model relates to a kind of lighting, the flat shell LED of particularly a kind of flat pattern illuminating lamp.

Background technology

Since the practical electric light of Edison in 1879, these great innovation and creation have been brought the mankind into and have been full of the bright and unlimited possible new century, the appearance of artificial light sources is known as the initial milestone of modern civilization society by International Technology circle, from having only the carbon filament electric light in 8 hour life-span the earliest, to incandescent tengsten lamp, the fluorescent lamp that excites to high-pressure fluorescence again, be to have experienced the very long road of seeking, up to the present, existing illuminating lamp mostly is incandescent lamp and fluorescent lamp, and most illuminating lamp is luminous high heat source body, and its heating efficiency is far longer than luminous efficiency, the 80%th, and the heat energy consumption, for lighting, its heat energy is useless often, wasted, caused great energy waste, also had the defective of not environmental protection; And, make lighting source be in work under the high hot state for a long time because its heat radiation is not smooth, and aging fast, life-span weak point,, cause a large amount of wastes of resource.The power consumption of China's illumination in a year at present surpasses 2,000 hundred million watt-hours, account for 12% of national power consumption, the utilization of resources also is much higher than other developed country, especially under the background that the worry of current global energy, shortage of resources raises once again, energy savings, resource are the important topics that we will face future, in this way, a kind of luminous efficiency height, good heat dissipation effect, long service life, the illuminating lamp of environmental protection is that people ask always again.

The utility model content

The technical problems to be solved in the utility model provides a kind of luminous efficiency height, the LED environmental protection illuminating lamp of good heat dissipation effect.

The utility model solves above-mentioned technical problem by following technical proposals:

A kind of novel flat shell LED illuminating lamp, comprising: one is applicable to the joint of general lighting lamp; It is some that one circuit board, circuit board are provided with potential device, fairing and lead, and circuit board is arranged in the cavity of joint; One metal shell, metal shell is fixedly connected to be installed on the joint; One heat sink, heat sink are located in the metal shell, and heat sink edge week closely contacts with the metal shell inwall; At least one light emitting source, the tight card of light emitting source is on heat sink, and described light emitting source is meant great power LED; One translucent cover, translucent cover are located on the metal shell, and described translucent cover exiting surface is the plane.

As the further improvement of a kind of novel flat shell LED illuminating lamp of the utility model, described heat sink is defined as heat conduction offset plate or aluminium base, in the hope of reaching better radiating effect.

For the illumination effect that makes a kind of novel flat shell LED illuminating lamp of the utility model better, more even, the well-regulated array of described some great power LEDs is on heat sink.

In order to make a kind of novel flat shell LED illuminating lamp of the utility model, not only have the inaccessible illuminating effect of general lighting lamp, and have higher ornamentally simultaneously, described heat sink is circular, ellipse or regular polygon.

The beneficial effects of the utility model are: owing to adopted LED to replace common incandescent lamp and fluorescent lamp as light emitting source, so compare common white heat and fluorescent lamp, has the luminous efficiency height, heating is few, advantages such as long service life, and heat sink of the present utility model in addition and metal shell two technical characterictics are formed the splendid cooling system of a radiating effect, can reach good heat-radiation effect, the LED light emitting source is worked under better environment, and aging speed is slower, so service life is better.

Description of drawings

Fig. 1 is stereoscopic figure of the present utility model;

Fig. 2 is the utility model cutaway view;

Fig. 3 is the utility model STRUCTURE DECOMPOSITION figure;

The specific embodiment

The present invention will be further described below in conjunction with drawings and Examples:

Referring to Fig. 1, stereo appearance figure of the present utility model, the parts that show from the outside have joint 6, and metal shell 3 is fixedly mounted on the joint 6, is a translucent cover 1 on the metal shell 3.

Cooperate and consult Fig. 2 and Fig. 3, cutaway view of the present utility model and exploded view, a kind of flat shell LED illuminating lamp of the utility model, form by joint 6, metal shell 3, translucent cover 1, LED light emitting source 2, heat sink 8 and circuit board 9, circuit board is provided with devices such as transformation 10, rectification 11, circuit board 9 is arranged in joint 6 cavitys, and joint 6 is as good as with the general lighting light fitting; The fixedly connected metal shell 3 that is equipped with on the top of joint 6, in metal shell 3, be provided with a heat sink 8, the edge week and the metal shell 3 inwall close contact of heat sink 8, make up the cooling system that radiating effect is splendid, the heat that is beneficial to that light emitting source is produced conducts in metal shell 3 by heat sink 8 heat and scatters and disappears, on heat sink 8, be provided with at least one LED light emitting source 2, LED light emitting source 2 is directly closely obedient on heat sink 8, compact conformation so not only, and be beneficial to heat radiation, reach best radiating effect; Heat sink 8 also can be arranged to difformity as required, as analogous shapes such as circle, ellipse, regular polygons, because the edge of heat sink 8 week closely contacts with the inwall of metal shell 3, so metal shell 3 can also need change with the change of shape of heat sink 8 by environment, form different face shapings, thereby reach commercialization, diversified elasticity selection effect; The exiting surface of translucent cover 1 is made as the plane, and lampshade is used the plate transparent glass cover instead and replaced traditional circular lampshade, makes structure, technology more simple, divergence of beam is more abundant, can be installed in the ceiling, light-emitting area and ceiling are in the same plane, reach better decorative effect.

Protection domain of the present utility model is not limited to claims, the specification described content, and other similar techniques scheme all belongs to the protection domain of the utility model.
