Abstract

The utility model discloses a novel LED fluorescent lamp tube which comprises a lamp tube, end caps on two ends and a printed circuit board, and is characterized in that the lamp tube comprises an aluminum extruded section bar and extrusion molding plastic rubber or an extrusion molding glass light transmission cover, wherein a clamping groove position is arranged in the lamp tube, the printed circuit board is placed in the lamp tube clamping groove position through a push type, and the end caps on two ends are formed by an aluminum alloy end cap and a plastic rubber connecting piece. The aluminum alloy end cap is mutually buckled with a column position in one end of a plastic rubber connecting piece through a hole site, and can not be rotated. The other end of the plastic rubber connecting piece is mutually mechanically buckled with a clamp position on the lamp tube through a clamp groove portion, and the lamp tube and the two end caps can not rotate. The LED fluorescent lamp has reasonable design, simple structure, strong structure reliability and high production assembly efficiency, is beneficial for LED to radiate heat, and has convenient use.

Description

A kind of LED fluorescent lamp tool

Technical field

The utility model belongs to lighting field, relates to a kind of LED fluorescent lamp tool.

Background technology

LED be called as the 4th generation lighting source, it compares conventional light source, and is particularly incandescent, halogen tungsten lamp, have significantly energy-conservation, environmental protection, long-life, volume is little, and light emission direction is strong, but the various indications of extensive use, show, decorate backlight, fields such as indoor and outdoor general illumination and urban landscape brightening illumination thereof.Particularly along with the developing rapidly of led chip technology and encapsulation technology, the LED light efficiency is increased substantially, light efficiency has surpassed 100LM/W at present.Just because of the raising of LED light efficiency, reach the requirement of indoor and outdoor versatility lighting field, and superpower energy-conservation, therefore environmental protection more and more receives the favor in general illumination market.Present general illumination field, using maximum is the fluorescence fluorescent tube, and the LED fluorescent tube relies on its significant performance, becomes to substitute a kind of novel daylight light fixture that has the fluorescence fluorescent lamp now.And at present on the market, also there are problems in the LED fluorescent lamp, adopts overall plastic such as fluorescent tube, fails effectively to solve the LED heat radiation, causes the LED temperature rise, and light decay is serious, and structural reliability is poor, and it is low inferior to produce efficiency of assembling.

Summary of the invention

The utility model based on above many deficiencies of existing market LED fluorescent tube, provides a kind of reasonable in design, simple in structure, and structural reliability is strong, is beneficial to the LED heat radiation, produces the efficiency of assembling height, LED daylight light fixture easy to use.

The technical scheme that its technical problem that solves the utility model adopts is as follows:

A kind of Novel LED fluorescent lamp pipe, form by fluorescent tube, two end cap and printed circuit board (PCB), it is characterized in that: fluorescent tube is made of Al squeezing material and crowded shape glue or crowded type glass diffuser, and there is the draw-in groove position fluorescent tube inside, and printed circuit board (PCB) places in the fluorescent tube draw-in groove position by push-in type; Two end cap is made of Aluminum Alloy Cover and plastic cement connector.

Described fluorescent tube is made of aluminium alloy extrusion section bar material and crowded type plastic parts or crowded type glass diffuser, and the band draw-in groove just can place printed circuit board (PCB) in the fluorescent tube by push-in type in the fluorescent tube, and printed circuit board (PCB) is made of full glass plate or aluminium base material.

Described two end cap is made of aluminium alloy and plastic cement connector, wherein respective post position, plastic cement connector rear end and Aluminum Alloy Cover corresponding hole site are fastened each other, and be unlikely to rotate, fluorescent tube inside is inserted in the corresponding screens of plastic cement connector front end, is unlikely to end cap and fluorescent tube rotates mutually.

The advantage of this structural design is as follows:

1, its lamp tube structure adopts aluminium extruded type material and crowded shape glue diffuser or crowded type glass diffuser to constitute, because the thermal conductivity of aluminium is fabulous, the heat that the LED lamp is produced, utilize the good heat dispersion of aluminium, make heat pass to the aluminium outer cover body earlier, by the aluminium surface heat is effectively distributed then, efficiently solve the problem of the temperature rise of LED, skin temperature at room temperature is controlled at below 50 degree, and internal temperature is controlled at below 60 degree.The printed circuit board (PCB) that the is welded with LED inner draw-in groove of the fluorescent tube position of need only push-in type just it can being packed into.

2, its diffuser adopts optical grade to squeeze type PC material or the crowded type glass diffuser of optical grade, and the light output of LED fluorescent tube is reached more than 90%. effectively improved the whole light efficiency of LED fluorescent tube.

3, two end cap that matches with fluorescent tube, it is made of Aluminum Alloy Cover and plastic cement connector, corresponding hole site and post position by design, Aluminum Alloy Cover and the effective mechanicalness of plastic cement connector one end are snapped together, and be unlikely to rotate, and the fastening of the inner screens machinery of the respective card slot position of the plastic cement connector other end and fluorescent tube, being unlikely to end cap integral body rotates with fluorescent tube, this kind structure has effectively been strengthened reliability of structure between fluorescent tube and the end cap, be unlikely to have between fluorescent tube and the end cap possibility of rotation, and this structure has improved the production efficiency of assembling greatly, and be beneficial to very much maintenance, saved the waste of material greatly and reduced maintenance cost.And the cage ring on the plastic cement connector is kept apart Aluminum Alloy Cover and fluorescent tube, plays certain reinforced insulation effect.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and instantiation.

Fig. 1 is a kind of schematic three dimensional views of structure of LED fluorescent tube.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and instantiation, but be not limited to this example.

Provide a representational instantiation below:

A kind of novel energy-conserving LED fluorescent tube is made up of fluorescent tube, two end cap and the printed circuit board (PCB) that is welded with LED.

Fluorescent tube is made of Al squeezing material 2 and crowded shape glue or crowded type glass diffuser 1.

There is draw-in groove position 22 fluorescent tube inside, is welded with LED printed circuit board (PCB) 3 and can places in the fluorescent tube draw-in groove position 22 by push-in type.

Two end cap is made of Aluminum Alloy Cover 5 and plastic cement connector 4.

Aluminum Alloy Cover 5 fastens each other by the post position 44 that position, hole 51 and plastic cement connect in part one end 43, is unlikely to rotate.

The plastic cement connector other end 41 is by the fastening of machinery each other of the screens 21 on its draw-in groove position 42 and the fluorescent tube, is unlikely to fluorescent tube and two end cap rotates.

The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
