Abstract

The utility model discloses an LED (light-emitting diode) ceiling lamp, which comprises a heat radiator, an aluminum substrate, a light source component, a lens, an inner ring, an intermediate ring and an outer ring. The light source component is arranged on the aluminum substrate, the aluminum substrate is connected with the heat radiator, the aluminum substrate, the light source component and the lens are arranged in the inner ring, the inner ring is arranged in the intermediate ring, the intermediate ring is arranged in the outer ring, the outer ring is provided with a spring plate, and the inner ring is butted with the heat radiator; and the heat radiator consists of a plurality of radiating plates, the bottoms of the radiating plates are connected, the upper parts of the radiating plates are arranged independently, and the surfaces of the radiating plates on the two outermost sides are provided with radiating grooves. Since the radiator consists of the radiating plates, the radiating plates gradually become thinner and thinner from bottom to top, and the outer surfaces of the radiating plates on the two outer sides are provided with the radiating grooves, the LED ceiling lamp has higher radiating performance, heat produced by the LED light source can be dissipated more promptly, the protection of the light source and drive components can be facilitated, the cost of maintenance can be reduced, and the service life of the light source and drive components can be prolonged.

Description

A kind of LED Ceiling light

Technical field

The utility model relates to technical field of lighting fixtures, is specifically related to a kind of LED Ceiling light.

Background technology

In the conventional art, Ceiling light generally adopts high reflector as reflector, adopts lamp holder that incandescent lamp bulb or energy-saving bulb are installed, and the lamp holder top is provided with terminal box, and its advantage is to be provided with terminal box, meets the fire-fighting requirement; Shortcoming is that lamp body is too high, and it is big to take up room, and light reflection utilization rate is low, and power consumption is big, bulb life is short etc.In order to reach energy-conservation purpose, now light sources that adopt LED as Ceiling light more, it adopts aluminium base usually, at aluminium base radiator is installed at the back, and its advantage is that energy saving, life-span are long; Shortcoming is that caloric value is big, and heat is difficult in time distributing, and the easy burn-out driven unit is safeguarded inconvenience, increases the operation and maintenance cost of lamp, reduces the service life of lamp, is unfavorable for applying of LED Ceiling light.

The utility model content

The LED Ceiling light that the technical problem that the utility model will solve provides a kind of simple in structure, good heat dissipation effect, be easy to safeguard, the life-span is longer.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LED Ceiling light is characterized in that: comprise radiator, aluminium base, light source assembly, lens, interior ring, middle ring and outer shroud; Light source assembly is installed on the aluminium base, and aluminium base is connected with radiator, and lens are installed in the light source assembly front; In encircling in aluminium base, light source assembly and lens are located at; In the ring, middle ring was located in the outer shroud during interior ring was located at, and outer shroud is provided with shell fragment; Interior ring docks with radiator, and shell fragment, outer shroud, middle ring, interior ring and radiator are fixed together; Said radiator is continuous by some bottoms, the separate fin in top constitutes, and the surface of fin offers the heat radiation groove, and being provided with of groove of heat radiation increased area of dissipation, therefore has stronger heat sinking function.

Preferably, said fin all serve as reasons the bottom toward the top structure of attenuation gradually, this structure more helps heat radiation.

Preferably, be parallel to each other between the said fin.

Preferably, said heat radiation groove is opened on the outer surface of two outermost fin.

Preferably, pass through sleeve pipe and bolt between shell fragment, outer shroud, middle ring and the interior ring.

The utility model is through making radiator the structure of being made up of the multi-disc fin; Every heat radiation attenuation gradually from the bottom up, and be provided with the heat radiation groove near the outer surface of the fin in the both sides outsides, thus make and the utlity model has higher heat dispersion; The heat that more can in time led light source be produced distributes; Help protecting light source and driven unit, reduce the cost of safeguarding, improve its service life.

Description of drawings

Fig. 1 is the utility model decomposition chart;

Fig. 2 is the utility model Facad structure figure.

Among the figure, 1 is radiator, and 2 is aluminium base, and 3 is lens, and 4 is interior ring, and 5 is sleeve pipe, and 6 is middle ring, and 7 is outer shroud, and 8 is shell fragment, and 9 is fin, and 10 are the heat radiation groove.

The specific embodiment

In the present embodiment, see figures.1.and.2 said LED Ceiling light; Comprise radiator 1, aluminium base 2, light source assembly, lens 3, interior ring 4, middle ring 6 and outer shroud 7, light source assembly is installed on the aluminium base 2, and aluminium base 2 is connected with radiator 1; Lens 3 are installed in the light source assembly front, in the ring 4, encircle in 6 during interior ring 4 is located in aluminium base 2, light source assembly and lens 3 are located at; Middle ring 6 is located in the outer shroud 7; Outer shroud 7 is provided with shell fragment 8, and interior ring 4 docks with radiator 1, and shell fragment 8, outer shroud 7, middle ring 6, interior ring 4 and radiator 1 are fixed together; Said radiator 1 is continuous by some bottoms, the separate fin 9 in top constitutes, and the surface of fin 9 offers heat radiation groove 10, and being provided with of groove 10 of heat radiation increased area of dissipation, therefore has stronger heat sinking function.

Fin 9 all serve as reasons the bottom toward the top structure of attenuation gradually, this structure more helps heat radiation.

Be parallel to each other between the fin 9.

Heat radiation groove 10 is opened on the outer surface of the outermost fin 9 in both sides.

Fixing between shell fragment 8, outer shroud 7, middle ring 6 and the interior ring 4 through sleeve pipe 5 and bolt (not shown).

Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
