Abstract

The utility model relates to a plug structure of an LED fluorescent lamp tube. The plug structure of the LED fluorescent lamp tube is characterized in that the plug comprises a plug front end and a plug rear end, wherein a plastic partition board is arranged at the bottom of the plug rear end, the plug front end and the plug rear end are assembled through movable buckles, the plug rear end is locked on an aluminum profile through a screw, and a power component is independently placed in a partitioned space formed in the way of buckling the plug front end and the plug rear end. The detachable plug front end and the detachable plug rear end are arranged, and the power component is separated from a PCB board of the LED and the aluminum profile through the plastic partition board at the plug rear end and placed in the plug, so that the structural design of the aluminum profile is not limited, the PCB board can be placed in the proper position so as to achieve the optimal optical effect, the lighting effect of the LED fluorescent lamp tube is more uniform, and bright and dim spots are eliminated; and in addition, two radiating ribs can be additionally arranged at the bottom of the aluminum profile, so that the thermal design is more reasonable, and the heat dissipation effect is better.

Description

LED fluorescent tube plug structure

[technical field]

The utility model relates to the LED lighting apparatus, relates in particular to the assembly structure of long strip type LED fluorescent lamp.

[background technology]

LED is as a kind of novel energy-conserving light source, develop very fast, progressively will replace traditional fluorescent lamp, has very big market potential, the cross section of LED fluorescent lamp is rounded on the market now, basically combine by the aluminium section bar of a semicircle and the PC diffuser of a semicircle, on the heat radiation lamp plate, arrange some light emitting LED lamp pearls, the light that LED lamp pearl produces sees through upper semi-circle PC diffuser and launches, at present the LED daylight lamp power source is built-in two kinds of structures basically, first kind of structure power supply is placed on the bottom of LED lamp plate, the LED pcb board is provided with than higher position in this structure, place power supply to the below and reserve enough big space, power making just can not be subjected to the constraint in space, and is more satisfactory from security.Meanwhile because the raising of LED pcb board, cause the position of LED to be raised, the spacing of LED distance P C diffuser peak reduces, the lighting angle of LED is limited, can only reach 120 °, and the LED of this structure is according to optical principle, the dark space can appear in the edge of obviously finding out the PC cover, What is more, because LED luminous point distance P C diffuser is too near, the mixed light of LED is inhomogeneous and the situation of bright spot occurs.Second kind of structure, power supply are placed on LED lamp bar two ends, and this design is too little in order to solve led light source distance P C cover distance, the problem of dark space or bright spot occurs, structure two light efficiencies are better, and lighting angle is bigger, the side reaches consistent substantially with front face brightness, and the mixed light effect also relatively evenly.But because power unit is placed on LED PCB both sides, PCB contacts with aluminium section bar and causes very big potential safety hazard like this.

[summary of the invention]

The utility model provides the LED fluorescent tube plug structure that a kind of lighting effects that can make the LED fluorescent lamp are better, the lampshade side does not have obvious dark space, heat radiation is more effective, security is higher, assembles on the structure simpler, practical.

The technical solution of the utility model is: the LED fluorescent tube plug structure that the utility model is related, it is characterized in that, plug is divided into plug front end and plug rear end, bottom, described plug rear end is provided with the plastic cement division board, described plug front-end and back-end are by the activity snap assembled, the plug rear end is locked to it on aluminium section bar with screw, and power supply module independently is placed on by plug front end and plug rear end and fastens in the insulating space that forms.

Be provided with the open-work that several supply lines connect on described plastic cement division board, the lead of power supply module is electrically connected with the PCB of LED by open-work.

Described plug front end has and stretches into inside, plug rear end, has the elongation end of protruding screens, and the bayonet socket of depression is arranged corresponding to the position of protruding screens in inside, plug rear end, finishes the activity snap assembled by bayonet socket and screens.

The beneficial effects of the utility model are: by detachable plug front end and plug rear end, the plastic cement division board of plug rear end is kept apart the pcb board of power supply module and LED and aluminium section bar, power supply module places in the plug, make the structural design of aluminium section bar unrestricted, thereby pcb board can be placed into a rational position reaches best optical effect, the illumination effect of LED fluorescent lamp more evenly, eliminate bright spot and dim spot.Can increase by two radiating ribs in the bottom of aluminium section bar in addition, heat dissipation design is more reasonable, and radiating effect is better.

[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.

Embodiment 1: the LED fluorescent tube plug structure that the utility model is related, it is characterized in that, plug is divided into plug front end 1 and plug

rear end

3,3 bottoms, described plug rear end are provided with plastic cement division board 6, described plug front end 1 and plug rear end 3 are by the activity snap assembled, described plug rear end 3 usefulness screws are locked to it on aluminium section bar 5, whole plug structure and aluminium section bar and PC diffuser 4 connect into complete fluorescent lamp, and power supply module 2 independently is placed on by plug front end 1 and plug rear end 3 and fastens in the insulating space that forms.

Be provided with several open-works 7 for the lead connection on described plastic cement division board, the lead of power supply module 2 is electrically connected with the PCB of LED by open-work 7.

Described plug front end 1 has the elongation end that has protruding screens 9 that stretches into 3 inside, plug rear end, and the bayonet socket 8.2 of depression is arranged corresponding to the position of protruding screens in 3 inside, plug rear end, finishes the activity snap assembled by bayonet socket 8.2 and card projection position 8.1.The movable connection method of plug front end and plug rear end is not limited to that this is a kind of, also can adopt the knob formula to connect, and tapping thread all in plug front end and plug rear end is used to connect both.
