Detailed description of the invention
Advantage of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
Consult Fig. 2 and Fig. 4, in wide-angle luminous intensity distribution illumination module of the present invention, include two LED lamp tube 100, wherein each LED lamp tube 100 includes the body 110 forming LED lamp tube 100 profile, a LED light source plate 120 is provided with in body 110, light source board 120 is provided with LED light source, and it is horizontally placed in body 110, and arranges along the axis of body 110.At this body 110 inwall, the part of body 110 inwall is made into micro-structural 111 form, and by the LED light source on LED light source plate 120 towards this micro-structural 111, thus the bright dipping directive micro-structural 111 of LED light source, utilize the characteristic of micro-structural 111, outgoing after the bright dipping of light source being assembled, then single LED lamp tube 100 times, can produce light distribution effect as shown in Figure 3, be similar to a flank body of a batswing tab, converging light can along the direction outgoing needed.In order to produce the effect being similar to both sides batswing tab luminous intensity distribution, parallel and the coplanar setting of two LED lamp tube 100, two LED lamp tube 100 are in same level and parallel to each other, namely both are symmetrical mutually with a perpendicular, consult Fig. 4, the light-emitting window 112 with micro-structural 111 of each LED lamp tube 100 is established dorsad, makes bright dipping respectively via the outgoing of micro-structural 111 meeting coalescence, thus produces batswing tab luminous intensity distribution as shown in Figure 5.Known, when the angle α of the LED light source plate 120 of two fluorescent tubes is larger, the illumination of batswing tab luminous intensity distribution more launches; On the contrary, when the LED light source plate 120 of two fluorescent tubes angle α more hour, the illumination of batswing tab luminous intensity distribution is more gathered.This angle α can meet in different application:
0°＜α＜180°。
And the size of this angle α is regulated according to different lighting condition.
The angle α of indication in above-described embodiment, is generally the angle between two surfaces that two LED light source plates 120 are provided with LED light source.If LED light source plate 120 is as flat board, then the angle between two LED light source plates 120 is this angle α.
Because the method for generation batswing tab luminous intensity distribution conventional at present increases by lens, to assemble bright dipping at the light-emitting window 112 of lighting.And in the present invention, utilize the characteristic of micro-structural 111, assemble bright dipping, and by tilting mutually for multiple LED lamp tube 100 producing same light-out effect, after crossing, reach the batswing tab luminous intensity distribution of effect same.In which, compared to the bright dipping of LED paster or the bright dipping of other lightings of routine, bright dark fringe effect can not be produced in lamp affixed to the ceiling, brightness uniformity in each polishing plane, and the fluorescent tube replaced in existing lamp affixed to the ceiling can be directly used in.
Can be preferably, angle α is between 60 ° to 100 °, namely the LED light source plate 120 in each LED lamp tube 100 and the angle of horizontal plane are between 40 ° to 60 °, under this angular range, the illumination even width of batswing tab luminous intensity distribution on transverse axis and y direction, is applicable to the occasion of more application batswing tab luminous intensity distribution as situations such as street lighting, desktop lamps.
In one embodiment, the body 110 of LED lamp tube 100 is cylindrical, identical with the shape of existing conventional fluorescent tube, then directly can apply replacement, the through setting of LED light source plate 120 axial directions along cylindrical tube 110, the length of whole LED lamp tube 100 is the bright dipping length of LED light source plate 120.And the micro-structural 111 of body 110 inwall, the then same axial direction along cylindrical tube 110 and establishing, and with the diameter of a radial direction for boundary, be arranged in the semicircle of this diameter side in body 110, towards light-emitting window 112, LED light source on LED light source plate 120 then just to micro-structural 111, bright dipping through micro-structural 111 assemble after outgoing.
Meanwhile, in order to even bright dipping, and reach the effect of total reflection, micro-structural 111 indentation, and its width and/or height are between 1mm to 2mm, are generally no more than the thickness of body 110.
Consult Fig. 6, in the present invention, light fixture also includes a lamp holder 200, two LED lamp tube 100 and can insert lamp holder 200 and be fixed in lamp holder 200.Lamp holder 200 is provided with two plug receptacles, and the opening direction of plug receptacle is consistent, thus makes two LED lamp tube 100 inserted can reach the setting of parallel co-planar.Contact the guide card be communicated with in lamp holder 200 with LED lamp tube 100 and in arbitrarily angled, then along the axial-rotation of LED lamp tube 100, just can change the angle [alpha] between LED light source plate 120 in two LED lamp tube 100.Also be knownly, if desired outside the bright dipping comparatively of batswing tab luminous intensity distribution side, side comparatively in, an equally also rotatable LED lamp tube 100, to reach the light-out effect of needs, two LED lamp tube 100 are only preferred embodiment with a perpendicular axial symmetry, and the non-limiting light fixture producing batswing tab luminous intensity distribution of the present invention.
Have embodiment illustrated in fig. 6 in light fixture after, can produce light distribution effect as shown in Figure 7, in this light distribution effect, there is not the defect of bright dark fringe in the bright dipping in the middle part of the LED lamp tube 100, the brightness uniformity in all directions, obtains splendid light-out effect.Consult Fig. 8 simultaneously, in the alternative lamp affixed to the ceiling 300 of wide-angle luminous intensity distribution illumination module 310 in the present invention, original fluorescent tube is directly placed, and be electrically connected with the power supply module in lamp affixed to the ceiling 300, mounting means is still identical with traditional approach, but light distribution effect is splendid as shown in Figure 7.In this embodiment, lamp affixed to the ceiling 300 also has a lampshade 320, is arranged on the light-emitting window of illumination module 310, to outgoing after the even light of the light of its outgoing.Be understandable that can have many group wide-angle luminous intensity distribution illumination module 310 in a lamp affixed to the ceiling 300, configure according to structure of ceiling-mounted lamp.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
