Abstract
The invention discloses a light-emitting diode (LED) straight tube lamp plug. The plug comprises a first drum part and a second drum part, wherein the first drum part is connected with a lamp tube, and the second drum part is connected with a power electrode. A first end of the first drum part is connected with a first end of the second drum part, a protruded structure extends on a drum wall of the first drum part in the first end direction from the second end, and the section of an inner cavity of the drum part axially corresponding to the protruded structure is not round. Relative rotation between the LED straight tube lamp plug and the lamp tube can be avoided, and the contact surface between the plug and the lamp tube does not need to be coated with an adhesion agent.
Description
Technical field
The present invention relates to lighting technical field, more specifically relate to a kind of LED straight lamp plug.
Background technology
LED light fixture has or not mercury, energy consumption is little, luminous efficiency is high advantage, as a kind of energy-saving lamp generally using, day by day replaces traditional tengsten lamp and fluorescent lamp.LED straight lamp is luminous evenly, bright, is easy to install, and is generally applied to office space, the fluorescence straight lamp before replacing.LED straight lamp generally includes fluorescent tube, be arranged on the light source board of the installation LED in fluorescent tube (as pcb board, PWA plate), be arranged on lamp tube ends for connecting the plug of light source board and power supply.
As shown in Figure 1, plug is two integrative-structures that the different cylinder of diameter forms to the structure of common LED straight lamp plug, and one end that diameter is less connects power electrode, and one end connecting tube that diameter is larger is about to fluorescent tube and is inserted into one end that diameter is larger.
Because the cross section of one end of fluorescent tube and plug connecting tube is circle, so easily rotate between fluorescent tube and plug, be difficult to location.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is exactly how to avoid relatively rotating between fluorescent tube and plug.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of LED straight lamp plug, this plug comprises first portion and second portion that is connected power electrode of connecting tube, wherein:
The first end of first portion is connected with the first end of second portion;
The barrel of first portion is extended with a bulge-structure to its first end direction from its second end, thereby the intracavity section of the axial corresponding cylinder portion of this bulge-structure is not circular.
Preferably, this bulge-structure is for radially outward protruding.
Preferably, this bulge-structure is inwardly protruding radially.
Preferably, first portion and second parts that portion is formed in one.
Preferably, first portion and second portion are the parts of two independent moulding linking together.
Preferably, the diameter of first portion is greater than the diameter of second portion.
(3) beneficial effect
LED straight lamp plug of the present invention can be avoided relatively rotating between plug and fluorescent tube, and can not need to contact-making surface coated with adhesive between plug and fluorescent tube.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the front view of traditional LED straight lamp plug;
Fig. 2 is according to the front view of the LED straight lamp plug of a preferred embodiment of the present invention;
Fig. 3 is according to the side view of the LED straight lamp plug of a preferred embodiment of the present invention;
Fig. 4 is according to the top view of the LED straight lamp plug of a preferred embodiment of the present invention;
Fig. 5 is the profile of cutting open along the A-A line of Fig. 4 according to the LED straight lamp plug of a preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples are used for illustrating the present invention, but can not be used for limiting the scope of the invention.
Fig. 2 is according to the front view of the LED straight lamp plug of a preferred embodiment of the present invention; Fig. 3 is the side view of this LED straight lamp plug; Fig. 4 is the top view of this LED straight lamp plug; Fig. 5 is the profile that this LED straight lamp plug is cut open along the A-A line of Fig. 4.Known in figure, LED straight lamp plug of the present invention comprises two cylinders 1 and 2 that diameter is different, cylinder 1 and 2 links together, one end of the cylinder 2 that diameter is less connects power electrode (not shown), one end connecting tube (not shown) of the cylinder 1 that diameter is larger, cylinder 1 forms a bulge-structure 3 for holding a part for the barrel of fluorescent tube, and this bulge-structure 3 extends to the direction near cylinder 2 from the opening part of cylinder 1.
Although shown in figure is that the diameter of cylinder 1 is greater than cylinder 2, both diameters also can equate or the diameter of cylinder 2 is greater than cylinder 1, and this depends on actual needs.Cylinder 1 and 2 is preferably integrated parts, and still also independent moulding links together again respectively.Plug also comprises the electrical structure part of the interior electric wire of connecting tube and external power source electrode, and this all belongs to prior art, does not repeat them here.
Bulge-structure 3 shown in figure is projections radially outward, but also inwardly protruding (not shown) radially, and this bulge-structure 3 axially intracavity section of corresponding cylindrical portions be circle.Accordingly, the fluorescent tube coordinating also should form radially outward projection or a radially inwardly protruded structure, thereby when fluorescent tube is inserted into cylinder 1, contact-making surface is between the two no longer a complete cylinder curved surface, but in a part on cylinder curved surface, forms radially outward projection or a radially inwardly protruded contact-making surface.Like this, as long as fluorescent tube is inserted into cylinder 1, between plug and fluorescent tube, just cannot rotate.Traditional technique often needs coated with adhesive to fix plug and fluorescent tube, and need to wait the adhesive cures mobile fluorescent tube of ability afterwards.From preventing the angle consideration in relative rotation of fluorescent tube and plug, the present invention can not need this procedure of coated with adhesive, has also saved the time of waiting for adhesive cures.As long as the suitable size that sets fluorescent tube and plug and the roughness of both contact-making surfaces, just can reach the object that direct grafting forms axial restraint, in addition, during installation, also can limit location to moving axially of plug, therefore, from the angle that prevents that fluorescent tube and plug from moving to axial, do not need coated with adhesive yet.
Above embodiment is only for the present invention is described, but not limitation of the present invention.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is carried out to various combinations, revises or is equal to replacement, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
