Abstract

A ring-shaped LED lamp comprises a ring-shaped lamp body made of transparent material; a plurality of mounting sleeves uniformly distributed at the periphery of the lamp body and communicated with the interior of the lamp body are formed through extending along the outer side surface of the lamp body to the tangential direction of the lamp body; an LED light bead and a convex lens arranged on the inner side of the light bead and used for converting the light emitted by the LED light bead into parallel light are arranged in each mounting sleeve; the LED light beads are connected to form a whole through connecting by conducting wires outside the lamp body; the lamp body comprises a reflective layer arranged on one side of the lamp body and a photic zone arranged on the side opposite to the reflective layer; and the light emitted by the LED light bead and converted by the convex lens is projected to the reflective layer and reflected to the photic zone by the reflective layer. The utility model has the advantages of simple structure, uniform lighting and energy conservation.

Description

The LED annular lamp

Technical field

The utility model relates to a kind of illuminating lamp; Especially a kind of LED annular lamp.

Background technology

Traditional sight lamp comprises that described bulb is fixed on the lamp socket in order to the bulb of illumination with in order to the lamp socket of power delivery to bulb, though this fluorescent lamp is simple in structure, in use, waste electric energy and illuminating effect are not good, so, the LED area source has just appearred.

Existing LED area source generally includes framework and the circuit board that is arranged on the framework, is fixed with a plurality of LED lamp pearls on described circuit board; Though the fluorescent lamp of the relative transmission of this kind structure LED area source has been saved electric energy, illuminating effect is significantly improved, but because the set LED lamp pearl of LED area source is more, and the space that it can energy savings is limited, and in long-term use, the easy light and shade inequality of LED area source overall light; Therefore, at the existing defective of existing LED area source, be necessary to design a kind of novel electricity-saving lamp.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of LED annular lamp, the luminous even and energy savings of this LED annular lamp.

For solving the problems of the technologies described above, the utility model adopts following technical proposals: the lamp body that this LED annular lamp comprises in the form of a ring and made by transparent material, extend to form a plurality of mounting sleeves that are distributed on described lamp body periphery and are connected to the lamp body tangential direction along described lamp body outer surface with described lamp body inside, be provided with LED lamp pearl and be arranged on LED lamp pearl inboard in order to LED lamp pearl emitted light is converted into the convex lens of directional light in each described mounting sleeve, described each LED lamp pearl is connected as one by the lead that is positioned at the described lamp body outside; Described lamp body comprises reflecting layer that is arranged on lamp body one side and the photic zone that is positioned at a relative side with described reflecting layer, the ray cast that the LED lamp pearl that transforms through described convex lens is sent to the reflecting layer and through described reflective layer reflects to photic zone.

According to design concept of the present utility model, described reflecting layer is formed by the reflection oil or the fluorescent material that are sprayed on the inner side of described lamp body.

According to design concept of the present utility model, described each LED lamp pearl is that serial or parallel connection connects.

Compared with prior art, LED annular lamp of the present utility model has following beneficial effect: because LED annular lamp of the present utility model evenly is provided with LED lamp pearl in the lamp body outside, this LED lamp pearl emitted light is converted into directional light through described convex lens, total reflection partly takes place in this directional light, wherein part light transfers to the lamp body outside through photic zone, and part light continues to propagate forward, and is luminous very even, and can realize the remote propagation of light; , can realize realizing illumination purposes with a spot of LED lamp pearl, further saved the energy.

The specific embodiment

Referring to Fig. 1, LED annular lamp of the present utility model comprises lamp body 1, this lamp body 1 in the form of a ring and made by transparent material, hollow form or entity shape can be made in its inside; The preferred PMMA material of its material.

Lateral surface at described lamp body 1 is provided with a plurality of mounting sleeves 11, and these a plurality of mounting sleeves 11 are to be provided with clockwise or counterclockwise, is the schematic diagram that six mounting sleeves 11 are provided with counterclockwise shown in the figure; Wherein, each mounting sleeve 11 is connected with described lamp body 1 inside respectively; Mounting sleeve 11 is distributed on the periphery of lamp body 1 and extends to lamp body 1 tangential direction along described lamp body 1 outer surface,

Referring to Fig. 2 and Fig. 3, in the utility model, in each described mounting sleeve 11, be provided with LED lamp pearl 12 and convex lens 13, wherein, each LED lamp pearl 12 by the lead 2 that is positioned at described lamp body 1 outside by polyphone or and the mode that connects connect as one; Convex lens 13 are in order to be converted into directional light to LED lamp pearl 12 emitted lights, and it is arranged on LED lamp pearl 12 inboards.

Described lamp body 1 comprises reflecting layer 14 that is arranged on lamp body one side and the photic zone 15 that is positioned at a relative side with described reflecting layer; Wherein, described reflecting layer 14 is formed by the reflection oil or the fluorescent material that are arranged on described lamp body 1 an inner side.This LED annular lamp is when work, the LED lamp pearl 12 that is positioned at described mounting sleeve 11 is luminous, this light transforms directional light through described convex lens 12, this directional light is incident upon on the reflecting layer 14, and after reflecting layer 14 reaches the external world to the part light emission to photic zone 14 through photic zone 14, and another part light is propagated forward lamp body 1 inner the continuation.

In sum, after 12 isolychns of LED lamp pearl act on through described convex lens, reflecting layer etc., part light is propagated through photic zone 14, part light continues at lamp body 1 internal communication, the comparatively dispersion that light becomes in communication process, all even soft, and because the utility model uses LED lamp pearl less relatively, therefore, it is simple in structure, has further saved the energy.
