The LED ceiling lamp is compact in structure, good in heat dissipation effect, long in service life, high in luminescent efficiency, even and gentle in luminescence.

Description

LED lamp affixed to the ceiling

Technical field

The present invention relates to a kind of LED lamp affixed to the ceiling, relate in particular to a kind of radiator structure of LED lamp affixed to the ceiling.

Background technology

LED lamp affixed to the ceiling of the prior art adopts LED luminescence component as light source, and light source and power supply are all arranged in the space that lampshade and base enclose, so the heat that causes light source and power supply to send is difficult to the lamp affixed to the ceiling that sheds, and fluorescent tube is easily burnt out.In addition, because power supply is arranged in lampshade, make light portion that light source sends by power supply stop, cause luminous efficiency not high, although light source is arranged between power supply and lampshade, can solve the problem that light is blocked, can cause lamp affixed to the ceiling thickness to increase.

Summary of the invention

The present invention is intended to solve above-mentioned mentioned technical problem, and a kind of compact conformation, good heat dissipation effect, long service life, high, the luminous uniform LED lamp affixed to the ceiling of luminous efficiency are provided.

The present invention realizes by following technical scheme:

LED lamp affixed to the ceiling, comprise base and be fixedly arranged on LED light source and power supply on base, on described base, be arranged with lampshade, described base is made of metal and has a circular profile, on described base, be provided with around the annular groove at base center, the cross section of described annular groove is inverted trapezoidal shape, described LED light source is close to the inside bottom of annular groove luminous towards the opening direction of annular groove, described power supply is close to the exterior bottom at base center, the edge of described base is provided with the flanging of lampshade dorsad, described flanging encloses the cavity that comprises power supply and annular groove, described LED light source is comprised of some LED luminescence components, between described LED luminescence component and base, be coated with heat dissipating silicone grease, on described lampshade, be coated with refraction film.

Further, the inner side of described base is coated with the insulating barrier with reverberation effect.

Further, described LED light source also comprises the low-light assembly being arranged on base, and low-light assembly is controlled its switching by optical switch.

Further, described flanging also offers some air vents.

Further, on described base, be also provided with installing hole.

The invention has the beneficial effects as follows: by annular groove is set on base, to increase the area of dissipation of base, power supply is arranged to the outside of base simultaneously, make radiating effect better, and avoided power supply to absorb the light that LED light source sends, thereby improve the luminous efficiency of LED light source, and by the refraction action of refraction film, the light that LED light source is sent is even, soft, natural.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, wherein:

Fig. 1 is LED lamp affixed to the ceiling cutaway view of the present invention;

Fig. 2 is the top view of the base in Fig. 1.

The specific embodiment

LED lamp affixed to the ceiling 1 as shown in Figure 1 and Figure 2, comprises base 2, LED light source, power supply 5, lampshade 3.LED light source, power supply 5, lampshade 3 are all fixedly arranged on base 2.

For ease of describing, base 2 is defined as to the inner side of base 2 towards a side of lampshade 3, a side of lampshade 3 is defined as the outside of base 2 dorsad.

Being made by metal material of base 2, its profile is rounded.On base 2, be provided with around the annular groove 20 at base 2 centers, LED light source is arranged at the inside bottom of annular groove 20 luminous towards the opening direction of annular groove 20, the cross section of annular groove 20 is inverted trapezoidal shape, on the inner side of base 2, be coated with the insulating barrier with reverberation effect, thereby wall 4 glazed threads that make LED light source be mapped to annular groove 20 can reflect outside annular groove 20 and the light that reflexes to base 2 medial surfaces can be reflected towards the direction of lampshade 3.

Lampshade 3 is threaded connection or mode and the base 2 of the routine such as buckle are connected and fixed, and is coated with refraction film on lampshade 3, and the direct light that LED light source sends is mixed, and makes that light is soft, nature.

Power supply 5 is arranged on the exterior bottom at base 2 centers, thereby has avoided in prior art, power supply 5 being arranged at the interior illumination effect that affects LED light source of lampshade 3.For the power supply 5 that is arranged on base 2 outsides is enclosed, make the area of dissipation that LED lamp affixed to the ceiling 1 integral body is more attractive in appearance and increase base 2, the flanging 23 of lampshade 3 is dorsad set at the edge of base 2, and flanging 23 encloses the cavity 24 that comprises power supply 5 and annular groove 20.For further increasing the radiating effect of LED luminescence component 6 and power supply 5, some air vents 21 are set on flanging 23, in the present embodiment, be provided with 4 symmetrically arranged air vents 21, air vent 21 can certainly gather on flanging 23.For base 2 is fixed on ceiling, on base 2, be provided with installing hole 22, the mode being connected by screw is fixedly connected with base 2 with ceiling.

LED light source is comprised of some LED luminescence components 6, in the present embodiment, adopt 3 annular LED luminescence components 6 of circular arc to be composed in series by wire 61, the same wire 61 that passes through of LED luminescence component 6 after series connection is electrically connected to the power supply 5 in base 2 outsides, and on corresponding position, offer and hold the wire guide that wire 61 passes on base 2, LED luminescence component 6 is fixedly arranged on base 2 by heat dissipating silicone grease, so the heat that sends of LED luminescence component 6 can be delivered on base 2 and dispels the heat.

For increasing the use function of LED lamp affixed to the ceiling 1, LED light source can also increase low-light assembly 7, low-light assembly 7 is arranged on the inner side of base 2 luminous towards lampshade 3, low-light assembly 7 is controlled its switching by optical switch, while not needing at night to use LED luminescence component 6 to throw light on, can enable low-light assembly and throw light on, as mini light night, use.

Above embodiment is only not limited in order to technical scheme of the present invention to be described, does not allly depart from any modification of spirit and scope of the invention or is equal to replacement, and it all should be encompassed in the scope of technical solution of the present invention.
