Description

A kind of LED Down lamp

Technical field

The utility model relates to a kind of LED lamp, particularly a kind of LED Down lamp.

Background technology

Along with advantages such as development and the LED light fixture of LED technology have energy saving, the life-span is long and radiation is low, the application of LED lamp is more and more extensive.Although the LED light fixture has many good qualities, also there are a lot of weak points.

Existing LED Down lamp holder structure is more complicated, usually is made from multiple components, and between each parts, is screwed, and causes the production procedure of LED lamp many, and production cost is high, installs and the maintenance inconvenience, and the problems such as screw dropout repeatedly easily occur after the maintenance.

In addition, the existing LED lamp ubiquity bad problem of dispelling the heat, can affect the service life of LED lamp if can not effectively dispel the heat.

The utility model content

The purpose of this utility model is, a kind of LED Down lamp is provided, and it has simple in structure, low cost of manufacture and installation and maintenance advantage easily, but also has good heat dispersion.

The technical solution of the utility model: a kind of LED Down lamp, comprise lamp socket, diffuser, LED circuit plate and the LED lamp pearl of integrated molding, diffuser is located on lamp socket, is provided with integrated inner casing in lamp socket, the LED circuit plate is located at the center of inner casing, and LED lamp pearl is located on the LED circuit plate; Between LED circuit plate, inner casing and lamp socket, by the swollen nail of core, be fixedly connected with.

In aforesaid this LED Down lamp, the side wall surface flare of described inner casing.

In aforesaid this LED Down lamp, the inwall of described inner casing is provided with reflective membrane.

In aforesaid this LED Down lamp, described inner casing adopts the sheet metal compacting to form.

In aforesaid this LED Down lamp, described sheet metal is iron plate, aluminium sheet or steel plate.

Compared with prior art, the utility model adopts integrated lamp socket and inner casing, has reduced production procedure, and the structure of LED lamp is simplified, and has solved more than traditional LED lamp part and the problem of production procedure complexity, effectively reduces production cost.Owing to being fixedly connected with by the swollen nail of core between LED circuit plate of the present utility model, inner casing and lamp socket, not only can effectively solve the screw dropout problem of traditional LED lamp, also have advantages of easy to installation and maintenance.

Inner casing of the present utility model adopts the sheet metal compacting to form in addition, not fragile on the one hand, can play the function of heat radiation on the other hand, can be effectively by being arranged on thermal release that LED circuit plate above it and LED lamp pearl produce in air, guarantee the service life of LED lamp.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Being labeled as in accompanying drawing: 1-lamp socket, 2-diffuser, 3-LED circuit board, 4-inner casing, 5-LED lamp pearl, the swollen nail of 6-core, 7-reflective membrane.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

Embodiment 1 of the present utility model: as shown in Figure 1, a kind of LED Down lamp, the lamp socket 1, diffuser 2, LED circuit plate 3 and the LED lamp pearl 5 that comprise integrated molding, diffuser 2 is located on lamp socket 1, be provided with integrated inner casing 4 in lamp socket 1, LED circuit plate 3 is located at the center of inner casing 4, and LED lamp pearl 5 is located on LED circuit plate 3; Between LED circuit plate 3, inner casing 4 and lamp socket 1, by the swollen nail 6 of core, be fixedly connected with.

The side wall surface flare of inner casing 4.The inwall of inner casing 4 is provided with reflective membrane 7.Inner casing 4 adopts the iron plate compacting to form.

Embodiment 2 of the present utility model: as shown in Figure 1, a kind of LED Down lamp, the lamp socket 1, diffuser 2, LED circuit plate 3 and the LED lamp pearl 5 that comprise integrated molding, diffuser 2 is located on lamp socket 1, be provided with integrated inner casing 4 in lamp socket 1, LED circuit plate 3 is located at the center of inner casing 4, and LED lamp pearl 5 is located on LED circuit plate 3; Between LED circuit plate 3, inner casing 4 and lamp socket 1, by the swollen nail 6 of core, be fixedly connected with.

The side wall surface flare of inner casing 4.The inwall of inner casing 4 is provided with reflective membrane 7.Inner casing 4 adopts the aluminium sheet compacting to form.

Embodiment 3 of the present utility model: as shown in Figure 1, a kind of LED Down lamp, the lamp socket 1, diffuser 2, LED circuit plate 3 and the LED lamp pearl 5 that comprise integrated molding, diffuser 2 is located on lamp socket 1, be provided with integrated inner casing 4 in lamp socket 1, LED circuit plate 3 is located at the center of inner casing 4, and LED lamp pearl 5 is located on LED circuit plate 3; Between LED circuit plate 3, inner casing 4 and lamp socket 1, by the swollen nail 6 of core, be fixedly connected with.

The side wall surface flare of inner casing 4.The inwall of inner casing 4 is provided with reflective membrane 7.Inner casing 4 adopts the steel plate compacting to form.

Operation principle of the present utility model: after energising, LED circuit plate 3 is 5 power supplies of LED lamp pearl, LED lamp pearl 5 is luminous, LED circuit plate 3 and LED lamp pearl 5 can produce a large amount of heats in work, because LED circuit plate 3 is arranged on inner casing 4, and inner casing 4 adopts metal materials to make, so the heat that inner casing 4 can produce LED circuit plate 3 and LED lamp pearl 5 effectively propagate in air, plays the function into LED circuit plate 3 and 5 heat radiations of LED lamp pearl.
