Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 solution adopted in the present invention is: the present invention includes 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 invention has the beneficial effects as follows: because heat dissipation plate of the present invention 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 present invention is simple in structure, excellent in heat dissipation effect;
Because the top of reflection shield of the present invention 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 light-emitting area of the present invention is big, light is soft;
Because the present invention is connected to heat dissipating ring in described heavy neck outer cover, described heat dissipating ring more can increase radiating effect, so radiating effect of the present invention is better;
Owing to be connected with the installation card on the reflection shield of the present invention, so the present invention is easy for installation.

The specific embodiment
Embodiment one:
As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes 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 produces when LED6 of the present invention is 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 of the present invention is not limited to described in the embodiment, can change according to the difference of power requirement.
The present invention can be widely used in the LED lighting field.
