Abstract

The utility model discloses a tube lamp comprising a lamp holder (1), a luminescent circuit board (2) which is arranged in the lamp holder (1), and an LED (3) which is arranged in the luminescent circuit board (2), and a lampshade (5) which is arranged under the luminescent circuit board (2), and an outer casing (6) which is sleeved outside the lamp holder (1) and fixes the lampshade (5) under the lamp holder (1), wherein, the upper part of the external side wall of the lamp holder is opened with a gap (11); the inner wall top of the outer casing (6) is correspondently provided with a convex buckle (61), and a ring liner (4) is further arranged between the lampshade (5) and the edge of the luminescent circuit board (2), and the thickness of the ring liner suits the distance between the edge of the luminescent circuit board (2) and the edge of the lampshade (5) edge. Compared with the prior art, the utility model connects the lamp holder and the outer casing fixedly by arranging the buckle of the outer casing in the external side gap of the lamp holder, and the buckle connecting mode is simple which lead to the practical assembly more easy and labor-saving, and is further easy to examine and repair interior.

Description

A kind of Down lamp

Technical field

The utility model relates to a kind of light fixture, especially refers to a kind of Down lamp.

Background technology

Raising along with people's living standard, the interior design development is swift and violent, the light fixture that only is used for room lighting, on market, emerge in an endless stream at present, various kinds such as Down lamp, shot-light, wall lamp, lamp affixed to the ceiling, pendent lamp, many, and style is a feast for the eyes, wherein, in the upholster in modern times, the use amount that count Down lamp is maximum.It is light emitting source that traditional Down lamp adopts based on halogen bulb, and its caloric value is bigger, the power consumption height, security performance is also relatively poor, generally using LED (light emitting diode) at present instead is light emitting source, and has advantages such as energy-conserving and environment-protective, illuminating effect is good, service life is long, therefore is subjected to consumer's favor.This Down lamp mainly includes lamp socket, be arranged in the lamp socket circuit board with and on LED, be arranged on the lampshade on the circuit board and be set in overcoat outside the lamp socket, wherein, the edge of lampshade just in time is positioned on the outer of lamp socket, put outward and be provided with internal thread, and be provided with external screw thread on the lamp socket accordingly, the edge of lampshade is fastened between overcoat and the lamp socket with being threaded of lamp socket by overcoat, thereby lampshade is fixed on the lamp socket.This mode that is threaded, when the actual installation Down lamp, just relatively require great effort, especially need maintenance when luminous the going wrong of LED, when perhaps changing circuit board and LED, at this moment, Down lamp has been installed on the indoor ceiling, power line connects with circuit board, and Down lamp just is difficult for wholely taking off from ceiling, so again the rotating jacket very effort that just seems.

Summary of the invention

Thereby technical problem to be solved in the utility model is to provide a kind of overcoat and lamp socket connected mode more simply to make easy more laborsaving, the Down lamp of being convenient to internal overhaul of practical set at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this Down lamp, include lamp socket, be arranged in the lamp socket circuit board with and on LED, be arranged on the lampshade under the circuit board and be set in outside the lamp socket and lampshade is fixed on overcoat under the lamp socket, it is characterized in that: the top of described lamp socket lateral wall offers breach, and the inwall top of described overcoat is provided with the buckle of protrusion accordingly.

Described circuit board can directly be fixed on lamp socket inside, but for ease of maintenance or replacing circuit board, this circuit board is to be movably arranged in the lamp socket to good, for making structure simpler, be easy to produce assembling, can be provided with a ring-type liner plate between the edge of described circuit board and the lampshade, the spacing at the thickness of this ring-type liner plate and circuit board and lampshade edge adapts, like this when assembling, adjust the position of circuit board in lamp socket earlier, again the ring-type liner plate is enclosed within outside the LED of circuit board, lampshade is covered under the ring-type liner plate then, and after overcoat was fixing with lampshade, ring-type liner plate and circuit board be being fixed within the lamp socket of nature just.

For further facilitating fixedly ring-type liner plate and circuit board, the lateral wall of described ring-type liner plate can be provided with the buckle of projection, and offer groove on the madial wall of described lamp socket accordingly, the card that is buckled in the lamp socket groove by the ring-type liner plate is established, and easily the ring-type liner plate is fixed on the lamp socket.

Compared with prior art, the utility model is established by the card that is buckled in the breach of the lamp socket outside that puts outward, makes firm the connecting of lamp socket and overcoat, and the connected mode of this buckle is simple, and practical set is easy more laborsaving, and is convenient to internal overhaul; In addition, the setting up of ring-type liner plate between circuit board and the lampshade makes circuit board fixedly become laborsaving in lamp socket, and be simple; The utility model is simple in structure, be easy to produce assembling, and light fixture is moulded succinct, attractive in appearance.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 3, this Down lamp, include lamp socket 1, be arranged in the lamp socket 1 circuit board 2 with and on LED3, be arranged on lampshade 5 under the circuit board 2, be set in outside the lamp socket 1 and lampshade 5 be fixed on overcoat 6 under the lamp socket 1;

The top of described lamp socket 1 lateral wall offers breach 11, and the inwall top of described overcoat 6 is provided with the buckle 61 of protrusion accordingly, establishes by the card of the buckle on the overcoat 6 61 in lamp socket 1 outside breach 11, makes lamp socket 1 and overcoat 6 firm connecting;

Also be provided with a ring-type liner plate 4 between the edge of described circuit board 2 and the lampshade 5, the spacing at the edge of the thickness of this ring-type liner plate 4 and circuit board 2 and lampshade 5 edges adapts, and, be provided with the buckle 41 of projection at the lateral wall of ring-type liner plate 4, and offer groove 12 on the madial wall of lamp socket 1 accordingly, establish by the card of this buckle 41 in lamp socket 1 groove 12, and easily ring-type liner plate 4 is fixed on the lamp socket 1.
