Description

A kind of fluorescent-lamp-type Universal LED fluorescent tube

Technical field:

The utility model belongs to lighting field, and particularly a kind of fluorescent-lamp-type Universal LED fluorescent tube especially is fit to make the small-sized fluorescent tube such as the T5 equal-specification.

Background technology:

Because the LED fluorescent tube is than straight tube fluorescent streetlamp energy-saving 50%, along with the development of LED technology, energy-conservation ratio also will continue to improve, and the fluorescent tube average life is short, contains the reasons such as mercury pollution, and straight tube fluorescent lamp is just progressively replaced by the LED fluorescent tube.At present profile is T8 (25.4 millimeters of diameter), and the LED fluorescent tube of T10 (31.8 millimeters of diameters), its aluminium section bar cooling stand have enough spaces driver module of packing into, therefore alternative existing T8, T10 fluorescent tube.But present T5 (diameter the is 15.875 millimeters) fluorescent tube of occuping market leading position, its space is little, if will replace to the LED fluorescent tube, then need manage the complicated circuit of packing into, and its structure whether reasonable in design directly affects the commercialization of T5.At present, also disclose some this type of patents in patent gazette, such as CN200820091435.1, a kind of LED universal lamp tube by name during its assembling, needs by instrument the assembly technology relative complex.

Summary of the invention:

The purpose of this utility model need not the fluorescent-lamp-type Universal LED fluorescent tube by instrument when being a kind of assembling of design.

Technical solutions of the utility model are achieved in that a kind of fluorescent-lamp-type Universal LED fluorescent tube, comprise lamp holder, T5 fluorescent tube specification aluminium section bar, pcb board, lampshade, be assemblied in LED lamp pearl and power module on the pcb board; Pcb board is fixed on the aluminium section bar, and lamp holder is installed in the aluminium section bar two ends, and is electrically connected with pcb board; It is characterized in that aluminum profile cross section becomes the semi arch moulding, radially form a mounting plane, long limit, mounting plane both sides convexes with respectively locking edge, article two, the one side that locking edge is relative has a reducing, one side mutually far away has a buckling groove that can allow lampshade slip into, the back side disjunctor of described mounting plane has radiating fin, and the radiating fin end consists of the semi arch moulding; Described mounting plane surface is coated with heat conductive silica gel, and pcb board is parallel to be pressed among two locking edges, and by the systolic pressure of the lampshade of outer button, draw-in groove both sides aluminium section bar pushes inwardly, clamp pcb board, therein clamping by the reducing of two locking edges, close adhesion is on described mounting plane; The lamp holder inboard is with the electroconductive elastic sheet that is electrically connected with the lamp holder external electrode, and lamp holder is installed in the aluminium section bar two ends, and the shell fragment that is in place distortion is conflicted on the pcb board conductive contact, forms to be electrically connected, and lamp holder utilizes colloid to cement in the aluminium section bar end.During whole fluorescent tube assembling, need not by instrument, screw, utilize colloid and material to cooperate the location.

Described lamp holder is the outer polygonized structure of inner circle, and the center of inner circle toward aluminium section bar one lateral deviation from; Corresponding lampshade one side of described lamp holder has an extension.The eccentric design of lamp holder both can prevent from rolling when the round lamp tube storage from placing, and also can avoid operator's wrongly installed direction, moreover the outer polygon design of lamp holder, the person of being easy to use is by tool operation, and the extension of corresponding lampshade one side loads and unloads fluorescent tube in the time of can avoiding the fluorescent tube waste heat loose and irons hand.

The mounting plane back side of described aluminium section bar is domes, and its cross section thick middle is gradually toward the both sides attenuation; Described radiating fin is distributed on the described domes surface.Thicken in the middle of the aluminium section bar and be conducive to the heat conduction.

Described lamp holder forms the plug tenon of disjunctor inwardly, is plugged in by this plug tenon in the gap of aluminium section bar radiating fin, forms embedded location structure.

The utility model structure is ingenious, reasonable in design, assemble simple characteristics; Assembling process need not by upgrade kit, does not connect wire bonds, the operation such as also maintains easily.

The specific embodiment:

See figures.1.and.2, take T5 fluorescent tube specification as example, fluorescent-lamp-type Universal LED fluorescent tube comprises the aluminium section bar 1 of T5 fluorescent tube specification, lamp holder 2, pcb board 3, and lampshade 4 is assemblied in LED lamp pearl 5 and power module 6 on the pcb board 3; In this structure, the resolution element 61 of power module 6 is welded on respectively pcb board 3 two, and LED lamp pearl 5 is welded on the centre, avoids resolution element 61 to take intermediate space.Aluminium section bar 1 cross section becomes the semi arch moulding, radially form a mounting plane 11, long limit, mounting plane 11 both sides convexes with respectively locking edge 12, article two, locking edge 12 relative one sides have a reducing, this reducing is formed by the little convex edge 121 of locking edge 12 ends, and one side mutually far away has a buckling groove 122, and the flanging 41 that falls of lampshade 4 both sides can slip into location in this buckling groove 122, otherwise also two locking edges 12 is formed constraint; The back side disjunctor of described mounting plane 11 has radiating fin 13, and radiating fin 13 ends consist of the semi arch moulding; More particularly, the mounting plane back side of aluminium section bar 1 is domes, and its cross section thick middle toward the both sides attenuation, is beneficial to heat conduction gradually, and described radiating fin 13 is distributed on the described domes surface.

The installation of pcb board 3, described mounting plane 11 surfaces are coated with the heat conductive silica gel with high bonding force, pcb board 3 parallel being pressed among two locking edges 12, and by the systolic pressure of the lampshade 4 of outer button, draw-in groove both sides aluminium section bar pushes inwardly, clamps pcb board 3, also namely need not screw and fixes, can be therein clamping by the reducing of two locking edges 12, close adhesion is on described mounting plane 11.The pcb board 3 that this example is mentioned is to adopt the high heat conduction CEM-3PCB of the R1787 of Panasonic plate.

Lamp holder 2 inboards are with the electroconductive elastic sheet 22 that is electrically connected with lamp holder external electrode 21, and lamp holder 2 is installed in aluminium section bar 1 two ends, by the colloid cementation; Moreover lamp holder 2 forms the plug tenon 24 of disjunctor inwardly, can be plugged in the gap of aluminium section bar radiating fin 13 by this plug tenon 24, forms embedded location structure.Lamp holder 2 is in place, and its shell fragment 22 distortion are conflicted on pcb board 3 conductive contacts, forms to be electrically connected, and need not screw locking or welding.In addition, lamp holder 2 is the outer polygonized structure of inner circle, and the center of inner circle toward aluminium section bar 1-lateral deviation from; Described lamp holder 2 corresponding lampshade 4-sides have an extension 23, the need of handing when this extension 23 provides operation, and the loading and unloading fluorescent tube irons hand when avoiding the fluorescent tube waste heat loose; And lamp holder 2 outer surfaces become polygonized structure, such as hexagon or octagonal, both can prevent that fluorescent tube from rolling, when block between lamp holder and the lamp socket too tight the time, also can by tool operation, overcome traditional circular base surface skidding.
