Abstract
The utility model discloses a light-emitting diode (LED) fluorescent tube, which comprises a shell part and a groove part for placing a printed circuit board (PCB). Two ends of the shell part are respectively provided with a position-clamping part fixed with a transparent polycarbonate (PC) cover, the groove part is arranged inside a shell body part and connected with the position-clamping part together, and a beveled light-reflecting part is respectively arranged between the groove part and the position-clamping part. After adopting the design, the LED fluorescent tube can fundamentally resolve the problems that like products have insufficient luminous flux, uneven light emitting and obvious shadow on two sides, ensures characteristics that a space is capable of internally accommodating a power supply and the like, and has better technologic effect.
Description
Technical field
The utility model relates to a kind of fluorescent tube, especially refers to the fluorescent tube external member on a kind of LED of being applied to fluorescent lamp, belongs to lighting field.
Background technology
Light-emittingdiode (English: Light-Emitting Diode, be called for short LED) be a kind of semiconductor element.At the beginning indicator lamp, display boards etc. of being used as more; Along with the appearance of white light emitting diode, also be used as illumination.
It is the new type light source of 21 century, has long, conventional light source such as the cracky advantage that can't compare with it not of efficient height, life-span.When adding forward voltage, the light-emitting diodes physical efficiency is sent monochrome, discontinuous light, and this is a kind of of electroluminescent effect.Change the chemical composition of the semi-conducting material that is adopted, can make light-emittingdiode be emitted near ultraviolet ray, visible light or ultrared light.
In general, the most important part of LED lamp is the LED fluorescent tube, and in general, it mainly includes a shell that acrylic/aluminium alloy is made, and the LED lamp is arranged on enclosure and shell and a transparent PC cover and is fixed together.
The LED fluorescent tube of said structure, be we present known a kind of structure.But, because technology is immature, said structure all can have clearly shadow and the phenomenon of light transmittance deficiency, this has also limited promoting the use of of LED fluorescent tube to a certain extent.
The utility model content
The utility model according to multi-faceted consideration and experimental results such as optics and mechanics, provides a kind of new LED fluorescent tube at the deficiency of existing LED fluorescent tube, and this fluorescent tube has the better illumination effect.
The utility model solves the problems of the technologies described above the technical scheme that adopted as following description:
A kind of LED fluorescent tube, comprise housing department and in order to place the concave part of pcb board, the two ends of described housing department are respectively arranged with and the fixing screens portion of transparent PC cover, described concave part is arranged on the inside of outer cover body portion, and portion links together with screens, also is respectively arranged with the light-reflecting portion on inclined-plane between described concave part and the screens portion.
Further, preferred construction is that the inclined-plane of described light-reflecting portion is Eight characters inclined plane shape to the both sides flare and outside being formed with.
Further, preferred construction is, described concave part comprises the vertical portion at planar portions and two ends, and described planar portions is to the recessed extension of shell subordinate.
Further, preferred construction is to be formed with the space between described vertical portion and the shell.
Further, preferred construction is that the height of described vertical portion is 10.5mm.
Further, preferred construction is that described PC cover is the thin structural design in thick middle both sides.
Further, preferred construction is that described housing department, concave part, screens portion and light-reflecting portion all are to take aluminum alloy materials to make.
Further, preferred construction is that described LED fluorescent tube is the fluorescent tube of T8 specification.
The beneficial effect that the utility model has been had after having taked technique scheme such as below description:
The first, because bevelled light-reflecting portion is set, therefore reduced angle of reflection, the minimizing loss of light source, strengthened the brightness of whole light fixture;
The second, be set to recessed owing to place the groove of PCB, PCB can allow the light gamut that light source exhaled be radiated on inclined-plane and the PC cover after pasting and putting, increased the light efficiency utilization rate of light source, increased the brightness of light fixture, and make on the PC cover luminous evenly, reduce shadow;
The 3rd, owing to leave the spatial altitude of 10.5mm, thereby solved the external problem of tube power palpus, the overall appearance and the harmony of fluorescent tube have been increased, and then fundamentally solved this series products luminous flux deficiency on the market, there is obvious shadow non-uniform light, both sides, and bag demonstrate,proved the space can built-in power etc. characteristics.
Description of drawings
By coming that below in conjunction with accompanying drawing the utility model is carried out further detailed description, above-mentioned advantage of the present utility model and technique effect will become more obvious.
Fig. 1 is the structural representation of the utility model LED fluorescent tube;
Fig. 2 is the profile of the utility model LED fluorescent tube.
The specific embodiment
Below in conjunction with accompanying drawing to the utility model be described in detail,
Fig. 1 is the structural representation of the utility model LED fluorescent tube.
As shown in Figure 1, this LED fluorescent tube fluorescent tube that is the T8 specification.
Described LED fluorescent tube includes housing department, concave part, screens portion and light-reflecting portion, described housing department 3 is a convex structure, and be provided with screens portion 4 at the two ends of housing department 3, described screens portion 4 is used for and PC cover link together (it is not shown that PC covers on embodiment).
Wherein, concave part generally is to be used to place pcb board, and light-reflecting portion 101 and 102 is a ramp structure, and is formed with the splayed inclined-plane each other, and above-mentioned inclined-plane plays a reflective effect.
Because above-mentioned design, we can reduce angle of reflection, the minimizing loss of light source well, have strengthened the brightness of whole light fixture.
Fig. 2 is the profile of the utility model LED fluorescent tube.
As shown in the figure, described concave part includes the vertical portion 202 at planar portions 201 and two ends, described planar portions 201 is to the recessed extension in housing department 3 places, adopt after this design, can allow the light gamut that light source exhaled be radiated on inclined-plane and the PC cover (not shown) after pcb board pastes and puts, can increase the light efficiency utilization rate of light source, increase the brightness of light fixture, and make on the PC cover luminous evenly, reduce shadow.
In general, dispel the heat with helping for the mechanical strength that increases light fixture, the housing department of described LED fluorescent tube, concave part, screens portion and light-reflecting portion all are to take aluminum alloy materials made.
And we make and leave certain spatial altitude between concave part and the housing department, and among the embodiment, the height of described vertical portion 202 is 10.5mm, thereby have solved the external problem of tube power palpus, have increased the overall appearance and the harmony of fluorescent tube.
