Abstract

The utility model discloses a round LED ceiling lamp, comprising a round lamp body, a light permeation cover, an LED light source module, a heat emission block, an LED drive module, an electric apparatus case and a ceiling piece, wherein a convex ring is on an inner wall of a lower part of the lamp, the heat emission block is of a concaved sturcture, heat emission ribs are arranged on an exine. The LED light source module is mounted in a cavity of the heat emission block, an end face at an open side of which is supported on a convex ring of a lower part of the lamp. The LED light source module comprises LED light source and a lens. The LED may be homogeneous light or polychromatic light, single grain or multi-grain. The light permeation cover is equispaced with a hexagon boss, thereby effectively preventing glare. The LED drive module is mounted in an electric apparatus case, which is connected with a ceiling piece through a positioning spring. The LED drive module is provided with a temperature control circuit and a light change circuit. The light fitting is good in heat emission, long in service life, a luminescent state of the LED is controlled, causing the light fitting to be present with ample colors and a plurality of changing forms, structure is simple, manufacture and assemble are convenient.

Description

The round LED Ceiling lamp

Technical field

The utility model relates to a kind of LED semiconductor lamp, especially relates to a kind of structure of round LED Ceiling lamp.

Background technology

Down lamp is the light fixture that is contained in the roof, and it is widely used in the usefulness as accent light such as market, large supermarket, office space, hospital, school, hotel, high-end residential, but both brightening environment can beautify the environment again, be life increasing colour.

The Down lamp that generally uses adopts metal halide lamp or fluorescent lamp as light source more at present.This Down lamp power consumption is higher, heating is big, lamp tube service life is short, and photochromic soft inadequately, and it is dazzling that the human eye direct-view can be felt, even produce dazzle.

Led light source is because of its luminous efficiency height, and the monochromaticjty of light is good, can directly send coloured visible light, and is photochromic soft, and power consumption is few, long service life, and security reliability is strong, and caloric value is low, thereby obtains application more and more widely.But existing round LED Ceiling lamp is owing to adopt high-power LED as light source, and the low-power LED that its caloric value is more general is big, the long-time use, and the temperature in the light fixture increases, and causes the inner resistance of LED lamp to become big, and shortened its service life.

The utility model content

The technical problems to be solved in the utility model provides a kind of round LED Ceiling lamp of good heat dissipation effect.

For addressing the above problem, round LED Ceiling lamp of the present utility model, comprise circular lamp body, diffuser, the led light source assembly, radiating block, the LED driven unit, electrical equipment box and suction head part, inhale head part and be connected lamp body top, the led light source assembly comprises led light source and lens, lens and diffuser are installed on the led light source successively, the lamp body lower inner wall is provided with protruding circle, radiating block is a concave inward structure, its outer wall is provided with the heat radiation rib, the led light source assembly is installed in the cavity of radiating block, the end face of radiating block open side is supported on the protruding circle of lamp body bottom, the LED driven unit is installed in the electrical equipment box, and the electrical equipment box is connected on the outer wall of radiating block bottom, is connected with the suction head part by retainer spring.

After having adopted above structure, led light source assembly and LED driven unit are isolated mutually, and the heat that the LED driven unit produces can not pass to the led light source assembly, and the heat that the led light source assembly produces can distribute to the external world apace by the heat radiation rib on the radiating block.

The heat radiation rib can be radial, parallel strip or circular.

The LED driven unit can be provided with temperature-control circuit.So that temperature is automatically adjusted, the service life of protection electric elements and prolongation light source.

The LED driven unit can be provided with light adjusting circuit.So that free adjustment is carried out in brightness, satisfy the lighting demand of different occasions.

LED in the led light source assembly can be monochromatic light, polychromatic light combination gradual change or saltus step.

LED number can be for more than single or single in the led light source assembly.

The diffuser surface can be evenly equipped with the hexagon boss.Can make light fixture form the anti-dazzle effect.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
