Abstract

The embodiment of the utility model discloses an LED fluorescent lamp end cap, which is characterized by comprising a metal pipe with two opening ends. A plastic cement body is fixed to the position of one opening of the metal pipe, and a metal pin for connecting a power supply is arranged on the plastic cement body. The LED fluorescent lamp end cap has the advantages of beautiful structure, lower cost and fine heat dissipation.

Description

A kind of LED fluorescent lamp end cap

Technical field

The utility model relates to electronic applications, relates in particular to a kind of LED fluorescent lamp end cap.

Background technology

Existing fluorescent lamp end cap generally adopts following three kinds of modes.End cap shown in Figure 1 comprises that metal stamping stretches cover 10, be used to connect the metal needle 11 of power line and be used for that described metal needle 11 is fixed to described metal stamping stretching and covers insulation spacer 12 on 10.In the end cap of Fig. 1 metal stamping stretch cover 10 stretching limited by mould can not be too high.End cap shown in Figure 2 comprises vinyl cover 20 that forms by the injection moulding mode and the metal needle of fixing on it 11.End cap among Fig. 2 coats fluorescent tube by vinyl cover 20, and thermal diffusivity is bad.The end cap of Fig. 3 comprises the plastic cement pipe 30 that the injection moulding mode forms and is enclosed within the circuit connecting body that comprises all structures of end cap shown in Figure 1 on the described plastic cement pipe 30, complex structure, poor radiation.

The utility model content

The utility model embodiment technical problem to be solved is, a kind of LED fluorescent lamp end cap is provided, and structure is attractive in appearance, cost is lower, thermal diffusivity is good.

A kind of LED fluorescent lamp end cap that the utility model provides comprises:

A kind of LED fluorescent lamp end cap is characterized in that, comprising: an opening part of the metal tube of a both ends open, described metal tube is fixed with a plastic body, and described plastic body is provided with the metal needle that is used to connect power supply.

Preferable, the opening of described fixedly plastic body narrows with respect to the body of described metal tube.

Preferable, described metal tube is tubular.

LED fluorescent lamp end cap provided by the utility model cooperates plastic body to form the fluorescent lamp end cap by the metal tube of both ends open, appearance looks elegant, and cost is low, and the length of metal tube can cut as required and be any length, and thermal diffusivity is good, the structural strength height.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.

LED fluorescent lamp end cap provided by the utility model cooperates plastic body to form the fluorescent lamp end cap by the metal tube of both ends open, appearance looks elegant, and cost is low, and the length of metal tube can cut as required and be any length, and thermal diffusivity is good.

Fig. 4 is an example structure schematic diagram of LED fluorescent lamp end cap of the present utility model.

As shown in Figure 4, the LED fluorescent lamp end cap of present embodiment comprises metal tube 40, plastic body 41 and metal needle 42.Wherein, described metal tube 40 both ends opens, described plastic body 41 are fixed on an end opening 401 places of metal tube 40, and described metal needle is installed on the described plastic body 41.In the specific implementation, described metal tube 40 is fixed on the outside of fluorescent-lamp tube, can help fluorescent tube to dispel the heat, and therefore, its length can cut according to radiating requirements and be random length.Described plastic body 41, described metal needle 42 are fixed on the described metal tube 40 by injection molding way.Further, the shape of described metal tube 40 can be tubular or square or cross section is shapes such as hexagon, octagon.Further, Fig. 5 shows the cutaway view in the cross section of metal tube in the present embodiment.

Among other embodiment of LED fluorescent lamp end cap of the present utility model, as shown in Figure 6, the end opening 401 of metal tube 40 narrows with respect to the body of metal tube 40.In the specific implementation, described opening 401 does not limit with respect to size, the angle that the body of metal tube 40 narrows.As shown in Figure 7, plastic body 41, metal needle 42 are fixed on opening 401 places of metal tube 40 by injection molding way.

The LED fluorescent lamp end cap that the utility model embodiment provides cooperates plastic body to constitute by the metal tube of both ends open, appearance looks elegant, and cost is low, and the length of metal tube can cut as required and be any length, and thermal diffusivity is good, and this end cover structure intensity height.

Above disclosed only is the utility model preferred embodiment, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.

Claims

1. a LED fluorescent lamp end cap is characterized in that, comprising: an opening part of the metal tube of a both ends open, described metal tube is fixed with a plastic body, and described plastic body is provided with the metal needle that is used to connect power supply.

2. LED fluorescent lamp end cap as claimed in claim 1 is characterized in that the opening of described fixedly plastic body narrows with respect to the body of described metal tube.
