Description

A kind of both-end closing in LED tube light

Technical field

This utility model relates to a kind of illuminator, particularly a kind of both-end closing in LED tube light.

Background technology

At present, LED lamp tube on the market, its end cap generally includes end cover body, the side of end cover body forms the flange for sealing body end, the opposite side of described end cover body forms the protuberance mated with external power receptacle, the inner side of protuberance surrounds one for placing the accommodating area of external power receptacle, and the bottom of accommodating area is provided with the hole, location for fixing plug pin, when contact pin is installed in hole, location, then constitute an attaching plug, fluorescent tube can be directly connected with external power receptacle coupling, without by wire connecting power plug, this end cap is the same with the end cap of existing LED lamp tube, it is generally all flat mouth end face, do not take into full account the impact that fluorescent tube is illuminated by the connected mode of end cap end face and lamp tube end and supporting role thereof, its supporting role on fluorescent tube and the impact on fluorescent tube illumination range are all very big, often result in the supporting role to fluorescent tube to reduce, or cause reducing of fluorescent tube illumination range, block reduction luminous flux.

Additionally, existing LED lamp tube, generally, the lampshade of this fluorescent tube can only make semi-circular groove, semi-circular groove lampshade is fastened on radiation aluminium base, constitute overall fluorescent tube, utilize radiation aluminium base to dispel the heat, so, not only the structure of fluorescent tube is extremely complex, and the manufacture process of fluorescent tube also unusual very complicated, because wanting die casting aluminium base, production cost is also significantly high. Certainly, the power of this fluorescent tube can be made larger, to adapt to powerful radiating requirements, but the structure in the face of low power LED lamp tube, avoid the need for so, because a large amount of wastes of production cost and material cost so can be caused, therefore, have much room for improvement and design a kind of structure for low power LED lamp tube.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is in that to provide that a kind of supporting role for low power LED lamp tube, to fluorescent tube is higher, is more beneficial for increasing the luminous flux of fluorescent tube, both-end closing in LED tube light that illumination range is bigger.

This utility model solves its technical problem and be the technical scheme is that a kind of both-end closing in LED tube light, including glass lamp, the circuit board being arranged in glass lamp and the LED lamp bead be located on circuit board, the two ends of described glass lamp are provided with end cap, the two ends of described glass lamp are provided with the diameter round platform terrace less than glass lamp external diameter, and described end cap tips upside down on described round platform terrace and forms interference fit with round platform terrace.

Improving further, the inner side of described round platform terrace is provided with draw-in groove, and described end cap is provided with the back-off snap ring with draw-in groove interference fit.

Improving further, described round platform terrace is the cone slope that little outside, inner side is big, the inner surface of described end cap be big outside, inner side little and with inclined-plane in the back-off of the slope interference fit of round platform terrace.

Improving further, it is concordant with the periphery of rear end cap and the periphery of glass lamp that described end cap is sheathed on round platform terrace.

Improve further, fixed by binding agent adhesion between the back side and the inner headed face of glass lamp of described circuit board.

Preferably, described binding agent is silicone rubber or epoxy glue.

The beneficial effects of the utility model are: owing to end cap is to be set on described round platform terrace, the supporting role of fluorescent tube is higher, it is more beneficial for increasing the luminous flux of fluorescent tube, illumination range is bigger, additionally, fixed by binding agent adhesion between the back side and the inner headed face of glass lamp of described circuit board so that the structure of both-end closing in LED tube light is simpler, assembles more convenient. It is simultaneously as although glass tubing heat radiation does not have aluminium good, but better relative to plastic material, therefore, can be used for low power LED lamp tube, it is possible to dispel the heat preferably for LED lamp bead, ensure the service life of LED lamp bead, it is ensured that the quality of product, reduce again material cost simultaneously. Meanwhile, radiation aluminium base need not be manufactured, also simplify production technology and reduce material cost.

Accompanying drawing explanation

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

Fig. 1 is the stereochemical structure decomposing schematic representation of the first embodiment of the present utility model.

Fig. 2 is the stereochemical structure decomposing schematic representation of the second embodiment of the present utility model.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, this utility model one both-end closing in LED tube light, including glass lamp 1, it is arranged at the circuit board 2 in glass lamp and the LED lamp bead 3 being located on circuit board, the two ends of described glass lamp are provided with end cap 4, the two ends of described glass lamp are provided with the diameter round platform terrace 5 less than glass lamp external diameter, described end cap tips upside down on described round platform terrace and forms interference fit with round platform terrace, the supporting role of fluorescent tube is higher, it is more beneficial for increasing the luminous flux of fluorescent tube, illumination range is bigger, and, it is socketed by step surface, connect more closely reliable.

Preferred embodiment, as it is shown in figure 1, the inner side of described round platform terrace is provided with draw-in groove 51, described end cap is provided with the back-off snap ring 41 with draw-in groove interference fit, by draw-in groove 51 and back-off snap ring 41 tight fit, it is possible to prevent end cap from getting loose, it is ensured that quality and safety.
