Abstract

The utility model discloses an LED lamp which comprises a lampshade, a lamp cover, at least one LED lamp component that is arranged in the lampshade, and a bracket that is used for fixing the lamp, wherein, the outer side face of the lampshade is provided with a cooling rib, an installation base plate is arranged in the lampshade, the circumference of each LED lamp component on the installation base plate is provided with cooling fins and a plurality of ventilation holes are arranged on the lamp cover, the lampshade and the installation base plate. The LED lamp has the advantages that: the cooling fins are additionally arranged on the installation base plate and a smooth cooling channel is formed by the ventilation holes, the cooling capability of the LED lamps is largely strengthened, thereby ensuring the luminous efficiency of the LED lamps effectively, prolonging the service life of the LED lamps and leading the LED lamps to replace traditional incandescent lamps, halogen lamps and energy-saving lamps without the limit of the power.

Description

The LED light fixture

Technical field

The utility model relates to lighting, more particularly, relates to a kind of LED light fixture, and it can replace traditional incandescent lamp, Halogen lamp LED, electricity-saving lamp, and power is not limit.

Background technology

The LED light fixture appears at the sixties in last century, from that time, people just look forward to having one day LED light fixture can replace conventional bulb, but realize this dream, must solve two problems, be high power output and life problems, and the solution of these two problems all depend on the solution of LED node heat dissipation problem.

But in the middle of prior art, as shown in Figure 1, though the lampshade 1` of AR and PAR light fixture outside is provided with radiating ribs, but only be provided with a big installation base plate 11` in the lampshade, on installation base plate 11`, do not have other fin, so that radiating effect is bad, even it is also few to leave the space of driver for.

The utility model content

The purpose of this utility model is to overcome defective of the prior art, provides a kind of and not only be provided with radiating ribs outside lampshade, and also be provided with the LED light fixture of radiator structure on the installation base plate in the lampshade.

For achieving the above object, the technical scheme that the utility model provides is as follows: construct a kind of LED light fixture, comprise lampshade, light cover is installed at least one LED lamp assembly in the lampshade, and the fixing support of light fixture, the lateral surface of lampshade is provided with radiating ribs, in lampshade, be provided with installation base plate, on installation base plate, be provided with fin around each LED lamp assembly, on described light cover, lampshade and installation base plate, respectively be provided with some air-vents.

Described LED lamp assembly has 3 at least, and described fin comprises around the muscle between the ring-type fin of each LED lamp assembly and the two adjacent LEDs lamp assembly and becomes many muscle fin.

Each ring-type fin is provided with two ventilating openings, and it is on the circumference in the center of circle that the inner that a described ventilating opening and a muscle become many muscle fin is distributed in the light fixture center.

Described at least one LED lamp assembly in lampshade along annular arrangement, the center is provided with cylindric radiator structure in lampshade, cylindric radiator structure is concordant with the height of fin, its outer face is provided with some air-vents, and fin is extended respectively in its side between each adjacent LED lamp assembly.

Be provided with ring-type fin between described lampshade and the installation base plate, locating respectively to be provided with at least one breach over against each between the adjacent LED lamp assembly on the ring-type fin around described at least one LED lamp assembly.

The beneficial effects of the utility model are: owing on installation base plate, set up fin, and form unobstructed heat dissipation channel, strengthen LED light fixture heat-sinking capability greatly, thereby effectively guaranteed the luminous efficiency of LED lamp, prolonged the life-span of LED lamp.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model LED light fixture is described in further detail:

With reference to Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of LED light fixture is provided, comprise lampshade 1, light cover 2, be installed in 5 LED lamp assemblies 3 in the lampshade 1, and in order to the fixing lamp holder 4 of light fixture, lamp holder 4 comprises support 40 and AR bean container lamp head 41, can be connected to AR bean container lamp head 41 on the lamp body by support 40 like this, keep the profile of traditional AR.

The lateral surface of lampshade 1 is provided with radiating ribs 10, in lampshade 1, be provided with installation base plate 11, respectively be provided with fin 12 on installation base plate 11 around each LED lamp assembly 3, fin 12 comprises around the muscle between the ring-type fin 120 of each LED lamp assembly 3 and the two adjacent LEDs lamp assembly 3 and becomes many muscle fin 121.Each ring-type fin 120 is provided with two ventilating openings 122, and the inner that a ventilating opening 122 and a muscle become many muscle fin 121 is distributed in the light fixture center to be on the circumference in the center of circle, to be beneficial to dispersing of heat.On the light cover 2, on the sidewall of lampshade 1 and respectively be provided with some air-vents 13 on the installation base plate 11.Like this by a muscle become many muscle fin 121, ring-type fin 120 has increased area of dissipation, simultaneously by on the light cover 2, on the sidewall of lampshade 1 and installation base plate 11 be provided with some air-vents 13 and form heat dissipation channels, improved radiating efficiency greatly.

5 LED lamp assemblies 3 in lampshade 1 along annular arrangement, the center is provided with cylindric radiator structure 14 in lampshade 1, cylindric radiator structure 14 is concordant with the height of fin 12, its outer face is provided with some air-vents 140, fin 141 is extended respectively in its side between each adjacent LED lamp assembly 3, form accommodation space in the cylindric radiator structure 14, can installation of driver or performance heat sinking function.Be provided with ring-type fin 15 between lampshade 1 and the installation base plate 11, locating respectively to be provided with two breach 150, the further like this area of dissipation that strengthened over against each between the adjacent LED lamp assembly 3 on the ring-type fin 15 around 5 LED lamp assemblies 3.

According to test, use fitting structure of the present utility model, can replace 75-100 watt traditional AR bulb with 15-25 watt high-powered LED lamp and reach same illuminating effect, can reach 50,000 hours service life.
