Technical field

The utility model relates to a kind of lamps and lanterns, refer specifically to a kind of disc lamp that side is luminous.

Background technique

Existing disc lamp includes shell, LED light bar, diffuser plate, light guide plate, reflector and cover board, wherein shell It is designed to that hollow disc-shaped structure, the substrate of LED light bar are sticked on the medial surface of shell and structure annular in shape, LED light bar On LED chip towards enclosure interior, diffuser plate is placed on the interior gear of the lower port of shell along upper, and light guide plate is placed on diffuser plate On, and height is corresponding with LED light, reflector is located on light guide plate, and cover board is covered on the top of shell, by the upper port of shell Masking.Since disc lamp is side light emitting structure, it has the characteristics that illumination that is ultra-thin, and being widely used in cabinet etc..

But current disc lamp is because of mismachining tolerance, often after assembling reflector and cover board, in reflector and inner walls Between, have gap between cover board and shell, and LED light is adjacent to the gap, thus the surrounding at the disc lamp back side always have it is micro- Weak light appear and influence illumination and decorative effect, simultaneously because the presence of mismachining tolerance, it is also difficult to make reflector and its under Light guide plate, diffuser plate make well positioning,

Utility model content

For the current state of the art, the technical problem to be solved by the utility model is to provide one kind convenient for assembling and energy Prevent the disc lamp of back light transmission.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of disc lamp, include shell, LED light bar, diffuser plate, light guide plate, reflector and cover board, wherein housing design is at hollow disc-shaped structure, the base of LED light bar Plate is sticked on the medial surface of shell and annular in shape, the circumferentially spaced medial surface for being arranged in substrate of LED chip in LED light bar On, the diffuser plate is placed on the interior gear of the lower port of shell along upper, and the light guide plate is placed on above-mentioned diffuser plate, and height Corresponding with LED chip, the reflector is located on light guide plate, and the cover board is covered on the top of shell and the upper end by shell Mouth masking, it is characterised in that: the light blocking ring along reflector surrounding arrangement is additionally provided on the reflector, which breaks Face body design ovalisation, and lean against between shell upper port inner wall and reflector upper surface, have on the light blocking ring The upper plane to offset with cover board lower surface and the lower plane being placed on reflector upper surface, and the middle part setting of the cover board The recessed portion that oriented lower process and the surface between the upper plane and lower plane of the light blocking ring offset.

In order to further avoid the shaking that occurs after assembly, be additionally provided on the lower surface of the recessed portion can with it is anti- The elastomer block that tabula rasa offsets.The elastomer block is preferably several, is evenly distributed respectively, so as to uniform force application.

In the above embodiments, uprightly there are two interconnecting pieces being symmetrically set upwards in the upper port of the shell, It is provided with the inverted T-shape groove for folding up and setting for spring on each interconnecting piece, is then provided on the cover board corresponding with each interconnecting piece Notch, so that compact overall structure, and easily disc lamp can be installed on roof.

In the above embodiments, circumferentially spaced on the outer side surface of the shell to be equipped with multiple vertically extending radiating ribs Item is so more advantageous to the heat dissipation of lamps and lanterns to increase heat dissipation area.

Compared with prior art, since the utility model is additionally arranged the light blocking ring leant against on reflector, the gear is utilized Aperture can cover the gap between cover and housing inner wall, between reflector and inner walls, so as to effectively prevent Light is appeared from gap, while also by means of the cooperation between the light blocking ring and cover board, so that the cover board after assembling passes through gear Reflector, light guide plate and diffuser plate are fastened in shell by aperture, avoid the shaking phenomenon for being possible to occur after mounting.
