Abstract

The utility model discloses an LED (Light Emitting Diode) ring lamp. The LED ring lamp comprises an annular chassis, wherein the annular chassis is designed into an annular heat dissipation chassis with the heat dissipation performance, an LED light source is arranged on the annular heat dissipation chassis, the back surface of the LED light source is clung to the annular heat dissipation chassis, and the annular heat dissipation chassis can be used for directly and rapidly leading out heat generated by the LED light source so as to prevent the heat of the LED light source from accumulating, so that the temperature of the LED light source is kept in a working range, and the heat dissipation problem of the LED light source is solved; a plurality of heat dissipation rings arrayed in a concentric circle manner are arranged at the bottom of the annular heat dissipation chassis, and due to the arrangement of the heat dissipation rings, the heat dissipation area can be enlarged, and the heat dissipation speed is increased; heat dissipation grooves are formed among the heat dissipation rings at intervals, and air is allowed to pass the heat dissipation grooves so as to ensure that the heat dissipation rings fully contact with air, and the optimal heat dissipation effect is achieved.

Description

The LED circular lamp

Technical field

The utility model relates to the LED lighting field, particularly a kind of LED circular lamp of good heat dissipation effect.

Background technology

The LED circular lamp is to adopt a kind of light fixture for room lighting of LED light source as illuminator, the LED ring like light fitting has or not that mercury is nontoxic, no electromagnetic pollution, without characteristics such as harm ray and energy-conserving and environment-protective.Existing LED circular lamp generally is comprised of annular chassis and the LED light source be arranged in annular chassis, some LED circular lamp also is provided with diffuser, because LED light source is luminous, can produce heat, if the heat of the luminous generation of LED light source can not leave in time, can make the lamp interior temperature more and more higher, not only can accelerate LED aging, shorten its service life, when serious, can cause LED to burn, therefore need on the LED circular lamp, radiator structure be set, effectively solve the heat dissipation problem of LED circular lamp.

The utility model content

Main purpose of the present utility model is to provide a kind of LED circular lamp of simple in structure, excellent in heat dissipation effect.

The utility model proposes a kind of LED circular lamp, comprise annular chassis and be arranged on the LED light source in described annular chassis, described annular chassis is the circular radiating chassis, in the bottom on described circular radiating chassis, be provided with the donut of some centers of circle of take described circular radiating chassis as the center of circle, described donut is heat dissipating ring, between described heat dissipating ring, be spaced, form radiating groove.

Preferably, also comprise and the diffuser of the annular of described circular radiating chassis adaptation, described printing opacity cover cap is located on described circular radiating chassis.

Preferably, described diffuser is transparent or opaque.

Preferably, be packaged with casting glue in described circular radiating chassis, described casting glue is potted on described LED light source.

Preferably, described circular radiating chassis is that the metal material with heat conductivility is made.

The beneficial effect of LED circular lamp of the present utility model is: annular chassis is set to have the circular radiating chassis of heat dispersion, LED light source is arranged on the circular radiating chassis, and the circular radiating chassis is close at the back side of LED light source, the heat that the circular radiating chassis can directly produce LED light source is fast derived, prevent the heat accumulation of LED light source, make within the temperature of LED light source remains on working range, solve the heat dissipation problem of LED light source.And, in the bottom on circular radiating chassis, being provided with some heat dissipating rings that concentric circles is arranged that are, arranging of heat dissipating ring can increasing heat radiation area, improves radiating rate; In spaced formation radiating groove between heat dissipating ring, radiating groove, allow circulation of air, can guarantee that heat dissipating ring fully contacts with air, make radiating effect reach best.

The specific embodiment

Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Referring to figs. 1 through Fig. 4, one embodiment of the utility model LED circular lamp is proposed, LED circular lamp in this embodiment comprises annular chassis 10 and is arranged on the LED light source 20 in this annular chassis 10, and this LED light source 20 is annular, and annular chassis 10 is close at the back of LED light source 20.This annular chassis 10, for having the circular radiating chassis 10 of thermolysis, adopts the aluminium alloy of high thermal conductivity coefficient to make, and has heat conduction, thermolysis.Because LED light source 20 is arranged on circular radiating chassis 10, and circular radiating chassis 10 is close at the back side of LED light source 20, so, the heat that circular radiating chassis 10 can directly produce LED light source 20 is fast derived, prevent the heat accumulation of LED light source 20, make within the temperature of LED light source 20 remains on working range, solve the heat dissipation problem of LED light source 20.

In the bottom on circular radiating chassis 10, be provided with the some donuts of the 10De center of circle, circular radiating chassis as the center of circle of take, donut is heat dissipating ring 101, one-body molded with circular radiating chassis 10, heat dissipating ring 101 the area of dissipation that can increase circular radiating chassis 10 is set, improve radiating rate.In spaced formation radiating groove between heat dissipating ring 101, radiating groove, for circulation of air, can guarantee that heat dissipating ring 101 fully contacts with air, promote the dissipation of heat ability, make radiating effect reach best.

This LED circular lamp also comprises a diffuser with the annular of circular radiating chassis 10 adaptations, and this diffuser can be set to transparent or opaque.The printing opacity cover cap is located on circular radiating chassis 10, and for the protection of LED light source 20, and the light that LED light source 20 is sent is more even, makes the outward appearance of light fixture more attractive in appearance.

In addition, the mode that also can be used on the interior encapsulation casting glue in circular radiating chassis 10 replaces diffuser, and embedding casting glue on the LED light source 20 on circular radiating chassis 10 carries out packaging protection by LED light source 20.

Certainly, the LED circular lamp also can not arrange diffuser or not carry out the casting glue encapsulation.

These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
