A kind of LED fluorescent lamp tube
The utility model relates to a kind of fluorescent lamp, particularly relates to a kind of LED fluorescent lamp tube.
At present, LED fluorescent lamp tube is as a kind of house lighting for alternative tengsten lamp and fluorescent lamp, due to its have that energy consumption is little, light efficiency is large, without mercury, radiationless pollution and the advantages such as material reproducible utilization, in today of energy growing tension, be more and more subject to the welcome of consumer.
Chinese patent Authorization Notice No. is CN201439878U, authorized announcement date is that the utility model patent of on 04 21st, 2010 discloses a kind of LED fluorescent tube, comprise the lamp plate being provided with multiple LED bulbs, be positioned at the lampshade of described lamp plate face side, be positioned at the heat dissipation base of described lamp plate rear side and be arranged on the attaching plug of described lamp tube ends, wherein, described lampshade and described heat dissipation base mutually group connect, described lamp plate is fixed on heat dissipation base, the outer surface of described heat dissipation base is formed with multiple radiating fin, although this utility model is under identical appearance and size, heat dissipation base has larger area of dissipation, better radiating effect can be obtained, thus the service life of LED fluorescent tube can be extended.But the LED fluorescent tube of this structure is more loaded down with trivial details during fabrication, need with multiple screw, lamp plate to be fixed on foot of radiator, thus need consume the larger time on lamp plate and heat dissipation base, process multiple corresponding fixing hole to manpower, therefore manufacturing cost higher and assemble more loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of easy-to-assemble LED fluorescent lamp tube.
For solving the problems of the technologies described above, the utility model provides a kind of LED fluorescent lamp tube, comprise radiator and lampshade, described lampshade is connected with the face side of described radiator and forms the body of a longitudinal, the face side of described radiator is provided with pcb board, evenly spacedly on described pcb board be provided with plurality of LEDs wafer, plug is respectively arranged with at the two ends of described body, described plug comprises plug body, described plug body has a L shape step, the two ends of described pcb board are pressed on described radiator by L shape step respectively, described plug body is set with bearing, described bearing is set with plug housing, the connection of described plug housing and described body threaded engagement.
The back side of described pcb board is connected by the face side of heat conduction glue-line with described radiator.
The surface uniform interval of described radiator be formed with multiple fin.
The male and fomale(M&F) of the outer surface undulate of described radiator.
The wall of described radiator has multiple through hole.
The outer surface of described lampshade is provided with fluorescence coating.
Compared with prior art, the beneficial effects of the utility model are: because the pcb board in the utility model is fixing on a heat sink by the L shape step on plug body, and without the need to by any screw, therefore the utility model assembling is more convenient.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and embodiments, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, a kind of LED fluorescent lamp tube of the present utility model, comprise radiator 2 and lampshade 4, this lampshade 4 is connected with the face side of radiator 2 and constitutes the body 5 of a longitudinal, the face side of radiator 2 is provided with pcb board 6, evenly spacedly on this pcb board 6 be provided with many LED wafer 7 for luminescence, plug 8 is respectively arranged with at the two ends of body 5, this plug 8 comprises plug body 9, plug body 9 has a L shape step 10, the two ends of pcb board 6 are pressed on radiator 2 by L shape step 10 respectively, plug body 9 is set with bearing 11, bearing 11 is set with plug housing 12, the connection that this plug housing 12 coordinates with the end thread of body 5, it is concrete when plug housing 12 is tightened on body 5 completely, the two ends of pcb board 6 are pressed on radiator 2 by L shape step 10 on plug body 9 just respectively, namely the horizontal plane of L shape step 10 can stop pcb board 6 in the movement of vertical direction, the vertical plane of L shape step 10 can stop the movement of pcb board 6 horizontal direction.The mode of above-mentioned fixing pcb board 6, without the need to by any screw, is therefore assembled more convenient.
In addition, shown in Figure 1, in the utility model, the back side of pcb board 6 is connected with the face side of radiator 2 by heat conduction glue-line (not shown), can ensure, between pcb board 6 and radiator 2, there is larger heat exchange area like this, thus guarantee that the utility model has good radiating effect.Simultaneously, for increasing radiating effect of the present utility model further, be formed with multiple fin the outer surface of radiator 2 is evenly spaced, the existence of the plurality of fin makes the utility model be provided with larger area of dissipation, or the outer surface of radiator 2 is made into corrugated male and fomale(M&F), the utility model so also can be made to be provided with larger area of dissipation, or multiple through hole is set on the wall of radiator 2, inner and the outside exchange heat of radiator 2 further can be accelerated like this by through hole, such the utility model just can have better radiating effect, thus make the utility model have longer service life.The outer surface of lampshade 4 is provided with fluorescence coating (not shown), and due to the existence of this fluorescence coating, after lamp extinguishes, fluorescence coating still has remaining light to be existed, thus person easy to use carries out next step action by remaining light, reaches the object of person easy to use.
