Shown in 3, embodiments providing a kind of line source reflector, for reflecting the light of a LED line light source 20, this line source reflector includes roof 10, spectrum part 11, the first side wall 12 and the second sidewall 13.
Concrete, roof 10 extends longitudinally. It should be noted that LED line light source 20 generally can be formed according to predetermined arragement direction arrangement by plurality of LEDs point source, the plane that the optical axis of each LED point light source is constituted is centre of luminescence face. It is reflective median plane (" L face " in figure) by the plane of roof 10 decile in the horizontal of line source reflector.
Spectrum part 11 is formed at the middle part of described roof 10 transverse direction and extends longitudinally, and described spectrum part 11 is positioned at the inner surface of described roof 10 and has two crossing and symmetrical inclined-planes 111,112. Such as, in Fig. 1 example, the cross section of spectrum part 11 is isosceles triangle, and the face at the waist edge places such as two of isosceles triangle is namely as above-mentioned two inclined-planes 111,112.
The first side wall 12 and the second sidewall 13 are respectively formed in the both sides of described roof 10 transverse direction and extend longitudinally, when described LED line light source 20 is configured to be arranged in parallel with described roof 10, and light direction towards the centre position of described roof 10 transverse direction time, the Part I light that described LED line light source 20 sends is by forming the first reflection light L1 of general parallel orientation after the inner surface reflection of described roof 10.
The Part II light that described LED line light source 20 sends, by 111 primary events in described two inclined-planes, forms the second reflection light L2 of general parallel orientation after the inner surface secondary reflection again through described the first side wall 12.
The Part III light that described LED line light source 20 sends, by another 112 primary event in described two inclined-planes, forms the 3rd reflection light L3 of general parallel orientation after the inner surface secondary reflection again through described second sidewall 13; Described 3rd reflection light L3, the second reflection light L2 and the first reflection light L1 are parallel to each other.
It should be noted that the arragement direction of LED line light source 20 LED point light source that refer to LED line light source 20 on parallel with roof 10 is parallel with the bearing of trend of roof 10. Towards the centre position of described roof 10 transverse direction, the light direction of LED line light source 20 refers to that centre of luminescence face overlaps with reflective median plane.
As preferably, the first side wall 12 and the second sidewall 13 are symmetrical arranged.
That is, line source reflector is a kind of strip structure longitudinally stretching formation, including roof 10 and the first roof 10 and the second roof 10 laying respectively at roof 10 both lateral sides, the centre position of the inner surface transverse direction of roof 10 is formed with spectrum part 11, and this spectrum part 11 also extends longitudinally. Wherein, the light of LED line light source 20 injection, as four echo areas, is had reflection by the inner surface of roof 10, the inner surface of the first roof 10, the inner surface of the second roof 10 and two inclined-planes 111,112 of spectrum part 11.
Concrete, when LED line light source 20 is parallel with the roof 10 of line source reflector, and the light direction of LED line light source 20 towards the centre position of described roof 10 transverse direction time, the light that this LED line light source 20 sends can be divided into three parts, a part is for being positioned at centre of luminescence left side of face and the some light near this centre of luminescence face, this some light is Part II light (light within the scope of A1), another part is be positioned at centre of luminescence right side of face and the some light near this centre of luminescence face, this some light is Part III light (light within the scope of A2), a part is the Part I light (B1 being distributed in Part II light and Part III light periphery again, light within the scope of B2).
Wherein, Part I light is directly projected on the roof of line source reflector, reflexes to LED line light source 20 front by the reflection of the inner surface of roof and forms the first reflection light L1 of general parallel orientation; And Part II light is projected on an inclined-plane 111 of spectrum part 11 of line source reflector, reflex on the first side wall 12 by the reflection on this inclined-plane 111, reflex to LED line light source 20 front again through the reflection of the first side wall 12 and form the second reflection light L2 of general parallel orientation. That is to say, Part II light first passes through inclined-plane 111 primary event of spectrum part 11 to the first side wall 12, forms the second reflection light L2 of general parallel orientation again through the first side wall 12 secondary reflection to LED line light source 20 front. Part III light is projected on another inclined-plane 112 of the spectrum part 11 of line source reflector, reflex on the second sidewall 13 by the reflection on this inclined-plane 112, reflex to LED line light source 20 front again through the reflection of the second sidewall 13 and form the 3rd reflection light L3 of general parallel orientation. That is to say, Part III light first passes through another inclined-plane 112 primary event of spectrum part 11 to the second sidewall 13, forms the 3rd reflection light L3 of general parallel orientation again through the second sidewall 13 secondary reflection to LED line light source 20 front. And, the first reflection light L1, the second reflection light L2 and the 3rd reflection light L3 are parallel to each other.
Thus, the light that LED line light source 20 the sends reflection by line source reflector, form parallel rays and concentrate from the injection of line source reflector.
The line source reflector provided according to embodiments of the present invention, the feature of Gaussian beam distribution is sent out in conjunction with LED light source orientation, all light of LED line light source 20 all can be gathered in rising angle, there is good spotlight effect, and brightness uniformity, it is absent from two kinds of different hot spots of light and shade, simultaneously, when equal light source power, optically focused brightness can be greatly improved, give full play to the power savings advantages of LED.
In one embodiment of the invention, described the first side wall 12 is downward-sloping from right to left in the horizontal, and described second sidewall 13 is downward-sloping from left to right in the horizontal.
That is, the first side wall 12 formation relative to the second sidewall 13 "eight" shape symmetrical structure, when the Part II light of LED line light source 20 injection is projected to an inclined-plane 111 of spectrum part 11, and when it reflexes on the first side wall 12, light just can be reflected to form the second parallel reflection light L2 by the first side wall 12. In like manner, when the Part III light of LED line light source 20 injection is projected to another inclined-plane 112 of spectrum part 11, and when it reflexes on the second sidewall 13, light just can be reflected to form the 3rd parallel reflection light L3 by the second sidewall 13. So, Part II light and the Part III light of LED line light source 20 injection can be reflected to form directional light, play good spotlight effect.
In a preferred embodiment of the invention, the inner surface of roof 10 is cancave cambered surface, and the inner surface of described the first side wall 12 and the inner surface of the second sidewall 13 are cancave cambered surface or plane.
When the inner surface of this roof 10 is cancave cambered surface, when the inner surface of the first side wall 12 and the second sidewall 13 is cancave cambered surface or plane, Part I light in the light that then LED line light source 20 sends can be projected to roof 10 equably, owing to roof 10 is cancave cambered surface, so, on cancave cambered surface, the reflective median plane of light alignment of reflection is drawn close, and ultimately forms the parallel rays (i.e. first reflection light L1) parallel with reflective median plane.
When the inner surface of the first side wall 12 and the inner surface of the second sidewall 13 are cancave cambered surface or plane, Part II light in the light that LED line light source 20 sends passes through inclined-plane 111 primary event of spectrum part 11 to the inner surface of this first side wall 12, on cancave cambered surface or plane, the reflective median plane of light alignment of secondary reflection is drawn close, and ultimately forms the parallel rays (i.e. second reflection light L2) parallel with reflective median plane. In like manner, Part III light in the light that LED line light source 20 sends passes through another inclined-plane 112 primary event of spectrum part 11 to the inner surface of this second sidewall 13, on cancave cambered surface or plane, the reflective median plane of light alignment of secondary reflection is drawn close, and ultimately forms the parallel rays (i.e. threeth reflection light L3) parallel with reflective median plane.
That is, in the present embodiment, the inner surface of roof 10 is designed as cancave cambered surface, the inner surface of the first side wall 12 and the inner surface of the second sidewall 13 are designed as cancave cambered surface or plane, so that the light that LED line light source 20 sends can be completely reflected formation directional light, better spotlight effect can be played.
More favorably, in an example of the present invention, the interior surface curvature of roof 10 is more than the interior surface curvature of described the first side wall 12 and the second sidewall 13. So, it can be ensured that the light that LED line light source 20 sends has better spotlight effect.
With reference to shown in Fig. 5, in order to improve spotlight effect, LED line light source 20 is configured to towards the area P less than or equal to the greatest cross-section of described spectrum part 11 of the projected area on roof 10 direction, and the whole light in the beam angle of described LED line light source 20 are projeced into the inner surface of described roof 10 and two inclined-planes 111,112 of spectrum part 11. That is, the size of LED line light source 20 is less than the size of spectrum part 11, the angle (i.e. A1+A2+B1+B2) that the beam angle of LED line light source 20 is formed less than or equal to two end points of both sides on described roof 10 and the line at LED line light source 20 center.
It should be noted that the greatest cross-section of spectrum part 11 refers to by a horizontal plane, spectrum part 11 is carried out the section that cutting is formed, this section is parallel with LED line light source 20. Corresponding, when spectrum part 11 is isosceles triangle, the face at the place, base of greatest cross-section i.e. isosceles triangle.
If the projected area of LED line light source 20 is more than the area P of the greatest cross-section of spectrum part 11, then on the one hand, LED line light source 20 some light in the Part II light and Part III light in centre of luminescence face can not pass through two inclined-planes 111,112 of spectrum part and reflex to the first side wall 12 and the second sidewall 13, but reflect either directly through roof 10, directional light can not be formed after reflection, on the other hand, partially reflective light is likely to be stopped formation dark space by LED line light source 20, ultimately results in spotlight effect and substantially reduces.
If the angle (i.e. A1+A2+B1+B2) that the beam angle of LED line light source 20 is formed more than two end points of both sides on described roof 10 and the line at LED line light source 20 center, then in the emitting beam of LED line light source 20, some light is directly projected to the first side wall 12 outside roof 10 and on the second sidewall 13, light after spectrum part 11 a inclined-plane 111 can only being reflected due to the first side wall 12 carries out secondary reflection and forms parallel rays, light after another inclined-plane 112 reflection of spectrum part 11 can only be carried out secondary reflection and form parallel rays by the second sidewall 13. therefore, the light for being directly projected on the first side wall 12 and the second sidewall 13 can not form directional light after the first side wall 12 and the second sidewall 13 reflect.
In view of this, in the present embodiment, LED line light source 20 is configured to towards the area P less than or equal to the greatest cross-section of described spectrum part 11 of the projected area on roof 10 direction, then on the one hand, the first side wall 12 and the second sidewall 13 can be reflexed to respectively in inclined-plane, 11 two, portion 111,112 so that the LED line light source 20 Part II light near centre of luminescence face and Part III light can be split fully, eventually through forming directional light after side the first side wall 12 and the second sidewall 13 secondary reflection, on the other hand, the light of reflection will not be stopped by LED line light source.
And the whole light in the beam angle of LED line light source 20 are projeced into the inner surface of described roof 10 and two inclined-planes 111,112 of spectrum part, then the whole light in LED line light source 20 beam angle are divided into three parts; A part (B1, B2 range of light) is reflected to form directional light by roof 10; The be split inclined-plane 111 in portion 11 of another part (light within the scope of A1) reflexes to the first side wall 12, again through forming directional light after the first side wall 12 secondary reflection; Another inclined-plane 112 in a part of (light within the scope of A2) portion 11 that is split reflexes to the second sidewall 13 again, again through forming directional light after the second sidewall 13 secondary reflection. Thus, it is possible to realize whole light of LED line light source 20 are carried out reflecting condensation, the light beam angle ultimately formed is less.
It should be noted that as shown in Figure 4, the angle that two marginal points that on the luminous zone width of LED line light source 20, distance is maximum are formed with the binding site line of described spectrum part 11 and described roof 10 intersection respectively is ��.
When described first reflect light L1, second reflection light L2, the 3rd reflection light L3 parallel with the centre of luminescence face of described LED line light source 20 (L face) time, the light beam angle of this line source reflector is less than or equal to ��; When described first reflects light L1 and described centre of luminescence face angle, described second reflection light L2 and described centre of luminescence face angle, and described 3rd reflection light L3 and described centre of luminescence face angle is respectively less than or during equal to ��/2, the light beam angle of this line source reflector is between �� and 2 ��.
