Abstract
An LED fluorescent lamp comprises LED light sources, a light source PCB, an aluminum radiating section bar, a PC cover, a lamp holder and a driving power source. The LED light sources are arranged in a single row mode, are divided into a plurality of sets of string lights and are welded on the light source PCB. The aluminum radiating section bar and a clamping foot of the PC cover are connected together in a clamping mode through a clamping groove, and the light source PCB is firmly fixed on the aluminum radiating section bar. The lamp holder comprises a short plastic cement lamp holder and a long plastic cement lamp holder. The driving power source is placed inside the long plastic cement lamp holder, and a wire at the output end of the driving power source penetrates through a thread hole of the long plastic cement lamp holder and is connected with the input end of the light source PCB. According to the LED fluorescent lamp, the driving power source is placed inside the long plastic cement lamp holder, thus the working temperature of the driving power source and the working temperature of the LED light source can both be lowered, and the service life of the entire LED lamp is prolonged obviously. Meanwhile, the plastic cement lamp holders are of a slope shape and are used for an embedded grille lamp disc, the light outlet part of an LED lamp tube can completely fall into a light outlet space of the lamp disc, and the light flux utilization rate is higher. The LED fluorescent lamp is attractive in appearance and reasonable in structure.
Description
Technical field
The utility model relates to a kind of fluorescent lamp, especially a kind of T8 type LED fluorescent lamp.
Background technology
The LED fluorescent lamp has plurality of advantages such as life-span length, luminous efficiency height, has been widely applied to every field such as commerce, office, household now.The LED fluorescent tube of built-in driving power on the present market, driving power is placed in the cavity of aluminium heat sink section bar mostly, causes the lamp pearl temperature at the driving power back side than the height in other place, makes the LED lamp life-span shorten greatly, can not embody LED lamp superiority.
The utility model content
The utility model technical issues that need to address provide a kind ofly can take into account light-emitting area and lamp pearl temperature, and utilance height, lamp pearl operating temperature are low, the LED fluorescent lamp of long service life.
For addressing the above problem, technical solution adopted in the utility model is: a kind of LED fluorescent lamp, comprise led light source, the light source pcb board, the aluminium heat sink section bar, the PC cover, lamp holder, driving power, wherein the led light source single file is arranged, being divided into many group lamp series weldings is connected on the light source pcb board, the aluminium heat sink section bar is connected together by the card base of draw-in groove and PC cover, the light source pcb board is fixed on the aluminium heat sink section bar firmly, lamp holder comprises short plastic cement lamp holder and long plastic cement lamp holder, driving power is placed in the long plastic cement lamp holder, and the through wires hole that the lead of the output of driving power passes long plastic cement lamp holder links to each other with the input of light source pcb board.
Design has a groove in the middle of the two ends semicircle top surface plane of described aluminium heat sink section bar, will lack the plastic cement lamp holder by tapping screw and be fixed on the aluminium heat sink section bar with long plastic cement lamp holder.
Described short plastic cement lamp holder and long plastic cement lamp holder constitute by plastic cement lamp holder and Cap casing two parts, and its plastic cement lamp holder front end is the inclined-plane, and Cap casing is fixed by tapping screw and short plastic cement lamp holder or long plastic cement lamp holder.
The beneficial effect that adopts technique scheme to produce is: the utility model is placed on driving power in the long plastic cement lamp holder, and the operating ambient temperature of driving power and led light source all can reduce like this, makes obviously prolong the service life of the whole lamp of LED; Simultaneously, plastic cement lamp holder of the present utility model is the inclined-plane, is used for embedded grid lamp disc, and the bright dipping part of LED fluorescent tube is all dropped in the bright dipping space of lamp panel, is not stopped that by the lamp panel lamp body utilance is higher; The utility model LED fluorescent tube good looking appearance, rational in infrastructure.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, lack the plastic cement lamp holder, 2, the aluminium heat sink section bar, 3, the light source pcb board, 4, led light source, 5, the PC cover, 6, long plastic cement lamp holder, 7, driving power.
The specific embodiment
Below in conjunction with accompanying drawing utility model is done and to be described in further detail: as shown in Figure 1, a kind of LED fluorescent lamp comprises that aluminium heat sink section bar 2, PC cover 5, surface post the light source pcb board 3 of lamp pearl (led light source), long plastic cement lamp holder 6, lack plastic cement lamp holder 1, driving power 7.Wherein driving power 7 is placed in the long plastic cement lamp holder 6, and the heat of generation can not influence the temperature of lamp pearl on the light source pcb board, can also keep enough light-emitting areas.
Led light source 4 single files are arranged, being divided into many group lamp series weldings is connected on the light source pcb board 3, the two sides of aluminium heat sink section bar 2 are provided with the fixedly draw-in groove of PC cover 5, two side straight flanges of PC cover 5 are provided with two interior card bases, be complementary with the draw-in groove of aluminium heat sink section bar 2, PC cover 5 is connected together with aluminium heat sink section bar 2 identically, thereby light source pcb board 3 is fixed on the aluminium heat sink section bar 2 firmly.The through wires hole that the lead of the output of driving power 7 passes long plastic cement lamp holder 6 links to each other with the input of light source pcb board 3, design has a groove in the middle of the semicircle top surface plane of aluminium heat sink section bar 2, by tapping screw can with short plastic cement lamp holder 1 or long plastic cement lamp holder 6 be fixed in aluminium heat sink section bar 2 and PC covers on 5, the Cap casing that will lack plastic cement lamp holder 1 or long plastic cement lamp holder 6 with tapping screw is fixed at last; Described short plastic cement lamp holder and long plastic cement lamp holder constitute by plastic cement lamp holder and Cap casing two parts, and its plastic cement lamp holder front end is the inclined-plane, and Cap casing is fixed by tapping screw and short plastic cement lamp holder or long plastic cement lamp holder.
The utility model is owing to adopted the holder structure that one is long and the other is short, thereby solved the problem that bright dipping was blocked when existing LED fluorescent tube heat structure is unreasonable to be used with the grid light fixture is interior preferably, the life-span of LED fluorescent tube is obviously prolonged, in the grid light fixture, use utilance higher.
