Abstract

Disclosed is a tube which is provided with a luminous diode, which comprises a tube body, a luminous unit which is arranged in one pipe of the tube body, two conductive units which are connected with the luminous unit and are arranged on the tube body. The tube body has a pipe wall which has an identification and two limit conductive bars which are projected from the pipe wall to the pipe interior. The luminous unit comprises a circuit board which is limited and arranged between the limit conductive bars. A plurality of luminous diodes are connected and arranged on the circuit board. The luminous unit can be rightly arranged in the pipe of the tube body by locating the assembly position of the circuit board through the limit conductive bar, which simultaneously avoids the tube body and the luminous unit from rotating relatively after assembling, further ensuring the quality of the assembled tube.

Fluorescent tube with light emitting diode

Technical field

The utility model relates to a kind of with the fluorescent tube with light emitting diode of light emitting diode as light emitting source.

Background technology

The traditional fluorescent lamp pipe mainly is to utilize gas discharge to produce light source in design, but along with the light emitting diode of the power saving universalness of (Light Emitting Diode is called for short LED), has many lighting devices little by little to be replaced by light emitting diode at present.And the existing fluorescent tube 1 shown in Fig. 1,2 be exactly a kind of be the lighting apparatus of light emitting source with the light emitting diode, this fluorescent tube 1 is installed in 10 of the electrically conductive sockets at two intervals, each electrically conductive socket 10 all has the conductive jack 101 at two intervals.

And existing fluorescent tube 1 comprises: the tube body 11 that the cross section is a hollow round tubular, this tube body 11 have a tube wall 112 that centers on a central axis setting and define a pipeline 111, and this pipeline 111 has two spaced apertures ends 113.And this fluorescent tube 1 also comprises: plastic end cover on two openends 112 that are installed in tube body 11 respectively 12, two be inlaid in respectively on the end cap 12 and toward the outstanding conductive electrode of end opposite 13, one be positioned at pipeline 111 and and the circuit board 14 of conductive electrode 13 electrical connections, and the light emitting diode 15 on a plurality of ground connection mounting circuit boards 14 that is electrically connected.

This end cap 12 has a basal wall 121 that is resisted against tube wall 112 outer faces of tube body 11, and one ring stretch in the pipeline 111 and and the prominent ring wall 122 of tube wall 112 applyings, between the inner ring surface of the outer ring surface of above-mentioned prominent ring wall 122 and tube wall 112 with viscose combination regularly.And the two ends of this circuit board 14 borrow viscose to cohere regularly on the inner ring surface of two pleurapophysis ring walls 122.Described conductive electrode 13 all has two conduction inserted links 131 in the conductive jack that can be plugged in electrically conductive socket 10 101.

The fluorescent tube that tradition produces light source with gas discharge in use, because light source is toward penetrating from all directions, restriction on so when assembling is directionless, but existing fluorescent tube 1 with light emitting diode 15 in use, must allow light emitting diode 15 towards predetermined direction, just can reach the effect of illumination.For fluorescent tube 1 light emitting diode 15 after setting up can correctly be shone towards predetermined direction, should have fluorescent tube 1 now in assembling, must make the line of 131 of the conduction inserted links of conductive electrode 13 be parallel to the circuit board 14 that sets up for light emitting diode 15, when the angle of installing has deviation, will have influence on the angle after light emitting diode 15 is installed between the two.

And existing fluorescent tube 1 with light emitting diode 15 in design, 11 of this end cap 12 and tube bodies are the circles that can rotate mutually, and end cap 12,

tube body

11 and 14 also not location designs of circuit board, just fix to each other with viscose, therefore, accurately the line of parallel electrically conductive inserted link 131 is very difficult the time will to allow circuit board 14 in assembling.In addition, even if each element is accurately corresponding when assembling, but when fluorescent tube 1 preparation is erected at 10 of electrically conductive sockets, the assembler need rotate this fluorescent tube 1 usually, in the process of rotating assembling, and sometimes can't be firm in the mode that viscose is done to cohere, cause interelement relative rotation easily, when tube body 11,

end cap

12 and 14 of circuit boards produced rotation relatively, this conduction inserted link 131 just can't be accurately corresponding with circuit board 14, causes light emitting diode 15 correctly to shine towards predetermined direction.

The utility model content

The purpose of this utility model is to provide a kind of element the time to locate easily in assembling, and element can not rotate after assembling mutually, to guarantee the fluorescent tube with light emitting diode of preferable assembling quality.

Fluorescent tube of the present utility model comprises: tube body, one are installed in luminescence unit in the pipeline of tube body and two and luminescence unit and are electrically connected and are erected at conductive unit on the tube body, this tube body has a tube wall that defines this pipeline, and this luminescence unit comprises a circuit board, and a plurality of ground connection that is electrically connected is installed in the light emitting diode on the circuit board.

Of the present utility model being characterised in that: also have on this tube body two outstanding and be used for locating the spacing sliver of this circuit board in the pipeline from tube wall.

Beneficial functional of the present utility model is: by the spacing sliver of power circuit board location is set at tube body, can allow luminescence unit correctly be installed in the pipeline of tube body, avoid tube body and luminescence unit after assembling, to produce rotation relatively simultaneously, reach the purpose of guaranteeing assembling quality whereby.
