Abstract
The utility model discloses an adjustable LED (light-emitting diode) fluorescent lamp tube which comprises a PCB (printed circuit board) lamp board (2) which is provided with a plurality of LED light sources (4) at intervals uniformly. The adjustable LED fluorescent lamp tube is characterized by also comprising a light reflection board (6); at least one lateral side of the PCB lamp board (2) is provided with a rotary shaft (8); and the shaft (8) is connected with the light reflection board (6), and can drive the light reflection board (6) to rotate. The adjustable LED fluorescent lamp tube provided by the utility model has the advantages of adjustable illuminating area.
Description
Technical field
The utility model relates to a kind of fluorescent tube, relates in particular to a kind of adjustable LED fluorescent tube.
Background technology
At present, the LED fluorescent tube is as a kind of house lighting for substituting tengsten lamp and fluorescent lamp, because it has that energy consumption is little, light efficiency is large, without advantages such as mercury, radiationless pollution and material reproducible utilizations, in today of energy growing tension, more and more be subject to consumer's welcome.
The Chinese patent Granted publication number is CN201439878U, Granted publication day is that on 04 21st, 2010 utility model patent discloses a kind of LED fluorescent tube, comprise the lamp plate that is provided with a plurality of LED bulbs, be positioned at the lampshade of described lamp plate face side, the attaching plug that is positioned at the heat dissipation base of described lamp plate rear side and is arranged on described lamp tube ends, wherein, described lampshade and the mutual winding of described heat dissipation base, described lamp plate is fixed on the heat dissipation base, the outer surface of described heat dissipation base is formed with a plurality of radiating fins, although this utility model is under identical appearance and size, heat dissipation base has larger area of dissipation, better radiating effect can be obtained, thereby the service life of LED fluorescent tube can be prolonged.Can't regulate but its illuminating area is fixing, therefore have relatively poor defective and the problem of flexibility of using.
Summary of the invention
Technical problem to be solved in the utility model provides the adjustable adjustable LED fluorescent tube of a kind of illuminating area.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of adjustable LED fluorescent tube, comprise the PCB lamp plate, evenly spacedly on the described PCB lamp plate be provided with a plurality of led light sources, also comprise reflector, one axle that can rotate is installed at least one side of described PCB lamp plate, and described axle is connected with described reflector, and can drive described reflector rotation.
The end of described axle is mutually meshing with adjusting gear.
Described reflector be shaped as rectangle.
Compared with prior art, the beneficial effects of the utility model are:
Because adjustable LED fluorescent tube of the present utility model is provided with reflector, this reflector is connected with the side of PCB lamp plate by the axle that can rotate, when needs change the irradiated area of light, change the angle of reflector and PCB lamp plate by rotating shaft, just can increase or dwindle the irradiated area of light, therefore operate more conveniently, illuminating area of the present utility model is adjustable.
Description of drawings
Describe the utility model in detail below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present utility model.
Among the figure: PCB lamp plate 2, led light source 4, reflector 6, axle 8, adjusting gear 10.
The specific embodiment
As shown in Figure 1, adjustable LED fluorescent tube of the present utility model, include: a plurality of led light sources 4 on PCB lamp plate 2, the evenly spaced PCB of the being installed in lamp plate 2 and the reflector 6 of rectangle, one axle that can rotate 8 is installed on the side of PCB lamp plate 2, this axle 8 is fixedly connected with reflector 6 to make between reflector 6 and the PCB lamp plate 2 and forms angle, and can drive reflector 6 rotations, one adjusting gear 10 is arranged, the outside of stretching out lampshade of these adjusting gear 10 parts during assembling for easy to operate end at axle 8 is meshing.
When the user need to change the irradiated area of light, be with moving axis 8 rotations by rotating adjusting gear 10, the reflector 6 that rotarily drives of this axle 8 rotates, thereby changes the angle between reflector 6 and the PCB lamp plate 2, to realize the increase of irradiation area or to dwindle.
In sum, adjustable LED fluorescent tube of the present utility model has the adjustable advantage of illuminating area.
The above only is preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
