The utility model discloses an LED lamp, aiming to provide an LED lamp with simple structure and good heat radiation effect. The utility model comprises a reflector cover (1), a circuit board (4), a rear cover (5) and a plurality of LEDs (6) uniformly distributed on the top of the reflector cover (1), wherein, the circuit board (4) is positioned in the cavity of the rear cover (5). The LED lamp also includes a heat radiation disk (2), an insulation bottom plate (3) and an LED circuit board (8), wherein, the heat radiation disk (2) is fixedly connected with the reflector cover (1); the LEDs (6) have heat radiation housings and contact the reflector cover (1) through the heat radiation housings; and the LED circuit board (8), the insulation bottom plate (3) and the circuit board (4) are sequentially placed on the heat radiation disk (2), which is sealed by the rear cover (5). The utility model can be widely used for LED illumination field.

Description

A kind of LED light fixture
Technical field
The utility model relates to a kind of LED light fixture.
Background technology
LED has long advantage of luminous efficiency height, power saving and life-span, and it is used more and more widely.LED is applied to normal lighting, generally a plurality of power-type LEDs to be concentrated on the light fixture and use, therefore the heat radiation of LED becomes a key factor that influences LED light fixture user mode and life-span, but the general radiator structure complexity of existing LED light fixture, and radiating effect is not good.
So existing technology has the following disadvantages: complex structure, radiating effect are not good.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of LED light fixture of simple in structure, excellent in heat dissipation effect is provided.
The technical scheme that the utility model adopted is: the utility model comprises reflection shield, circuit board, bonnet, several LED, several described LED are distributed in the top of described reflection shield, described circuit board is positioned at the chamber of described bonnet, described LED light fixture also comprises heat dissipation plate, insulating base, the led circuit plate, described heat dissipation plate and described reflection shield are fixedly connected, described LED has heat-dissipating casing and contacts with described reflection shield by described heat-dissipating casing, places described led circuit plate on the described heat dissipation plate successively, described insulating base, described circuit board also passes through described bonnet sealing.
The top of described reflection shield is heavy neck, and described LED all is positioned at described heavy neck.
Be connected to heat dissipating ring in described heavy neck outer cover.
Be connected with the installation card on the described reflection shield.
The beneficial effects of the utility model are: because heat dissipation plate described in the utility model and described reflection shield are fixedly connected, described LED has heat-dissipating casing and contacts with described reflection shield by described heat-dissipating casing, the heat that produces when described LED is luminous is transmitted to described reflection shield and described heat dissipation plate by heat-dissipating casing, large-area described reflection shield and described heat dissipation plate can distribute heat rapidly, not only do not need complicated radiator structure but also good heat dissipation effect, can avoid LED high temperature, effectively increase the service life, so the utility model is simple in structure, excellent in heat dissipation effect;
Because the top of reflection shield described in the utility model is heavy neck, described LED all is positioned at described heavy neck, the light that described LED sends reflexes to described reflection shield again via described reflection shield ejaculation through the inwall of described heavy neck, the light that described LED sends is through reflection for several times, make light redistribution and evenly penetrate from the bigger described reflection shield of area, therefore light-emitting area is big, light is soft, can avoid causing various hot spots, so the utility model light-emitting area is big, light is soft;
Because the utility model is connected to heat dissipating ring in described heavy neck outer cover, described heat dissipating ring more can increase radiating effect, so the utility model radiating effect is better;
Owing to be connected with the installation card on the reflection shield described in the utility model, so the utility model is easy for installation.

The specific embodiment
Embodiment one:
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises reflection shield 1, heat dissipation plate 2, insulating base 3, circuit board 4, bonnet 5, several LED 6, led circuit plate 8, several described LED 6 are distributed in the top of described reflection shield 1, described circuit board 4 is positioned at the chamber of described bonnet 5, described heat dissipation plate 2 is fixedly connected by screw and described reflection shield 1, described LED 6 has heat-dissipating casing and contacts with described reflection shield 1 by described heat-dissipating casing, place described led circuit plate 8 on the described heat dissipation plate 2 successively, described insulating base 3, described circuit board 4 also passes through described bonnet 5 sealings, the top of described reflection shield 1 is heavy neck 10, described LED 6 all is positioned at described heavy neck 10, is connected with on the described reflection shield 1 card 7 to be installed so that install.
The heat that LED described in the utility model 6 produces when luminous is transmitted to described reflection shield 1 and described heat dissipation plate 2 by described heat-dissipating casing, large-area described reflection shield 1 and described heat dissipation plate 2 can distribute heat rapidly, not only do not need complicated radiator structure but also good heat dissipation effect, can avoid LED high temperature, effectively increase the service life, simple in structure, excellent in heat dissipation effect, and light-emitting area is big, light is soft.
Embodiment two:
As shown in Figure 4, the difference of present embodiment and embodiment one is: be connected to heat dissipating ring 9 in described heavy neck 10 outer cover, be beneficial to better heat radiation, present embodiment is applicable under the LED power condition with higher.
The number of LED 6 described in the utility model is not limited to described in the embodiment, can change according to the difference of power requirement.
The utility model can be widely used in the LED lighting field.
