13, then pass through 13 secondary reflection of second sidewall to the third reflection light L3 of 20 front formation general parallel orientation of LED line light source.And
And the first reflection light L1, the second reflection light L2 and third reflection light L3 are parallel to each other.
The light that LED line light source 20 is sent out as a result, is formed parallel rays and is concentrated by the reflex of linear light source reflector
It is projected from linear light source reflector.
The linear light source reflector provided according to embodiments of the present invention, in conjunction with the characteristics of LED light source orientation hair Gaussian beam distribution,
All light of LED line light source 20 can all be gathered in light-emitting angle, there is good spotlight effect, and brightness is equal
Even, there is no the different hot spots of two kinds of light and shades, meanwhile, in the case of same light source power, optically focused brightness can be greatly improved, is filled
The power savings advantages of LED are waved in distribution.
In one embodiment of the invention, the first side wall 12 tilts down from right to left in the horizontal, and described
Two side walls 13 tilt down from left to right in the horizontal.
That is, the first side wall 12 and the opposite formation "eight" shape symmetrical structure of second sidewall 13, when LED line light source 20
The second part light of injection is projected to an inclined-plane 111 of spectrum part 11, and when reflexing on the first side wall 12 through it, and first
Light can just be reflected to form the second parallel reflection light L2 by side wall 12.Similarly, when the third that LED line light source 20 projects
Some light is projected to another inclined-plane 112 of spectrum part 11, and when reflexing in second sidewall 13 through it, and second sidewall 13 is rigid
Light can be reflected to form to well parallel third reflection light L3.In this way, LED line light source 20 project second part light and
Part III light can be reflected to form directional light, play good spotlight effect.
In a preferred embodiment of the invention, the inner surface of roof 10 be cancave cambered surface, the first side wall 12 it is interior
The inner surface of surface and second sidewall 13 is cancave cambered surface or plane.
When the inner surface of the roof 10 is cancave cambered surface, the inner surface of the first side wall 12 and second sidewall 13 is cancave cambered surface or flat
When face, then first part's light in the light that LED line light source 20 is sent out can equably be projected to roof 10, due to roof 10
For cancave cambered surface, so, the light reflected on cancave cambered surface is drawn close to reflective median plane, is ultimately formed parallel with reflective median plane
Parallel rays (i.e. the first reflection light L1).
When the inner surface of the first side wall 12 and the inner surface of second sidewall 13 are cancave cambered surface or plane, LED line light source 20
In 111 primary event of inclined-plane to the first side wall 12 that second part light in the light sent out passes through spectrum part 11
Behind surface, the light of secondary reflection is drawn close to reflective median plane on cancave cambered surface or plane, is ultimately formed flat with reflective median plane
Capable parallel rays (i.e. the second reflection light L2).Similarly, the Part III light in the light that LED line light source 20 is sent out passes through
It is secondary on cancave cambered surface or plane after another 112 primary event of inclined-plane to the inner surface of the second sidewall 13 of spectrum part 11
The light of reflection is drawn close to reflective median plane, ultimately forms the parallel rays parallel with reflective median plane (i.e. third reflection light
L3)。
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 second sidewall 13 is designed as cancave cambered surface or plane, and the light that LED line light source 20 is sent out can be enable complete
Directional light is reflected to form, better spotlight effect is played.
More favorably, in the example of the present invention, the interior surface curvature of roof 10 is more than the first side wall 12
With the interior surface curvature of second sidewall 13.So, it can be ensured that the light that LED line light source 20 is sent out is imitated with better optically focused
Fruit.
Referring to Figure 5, in order to improve spotlight effect, LED line light source 20 is configured as towards on 10 direction of roof
Projected area is less than or equal to the area P of greatest cross-section of the spectrum part 11 on horizontal profile and the LED line light
Whole light in the beam angle in source 20 are projeced into the inner surface of the 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 beam angle of LED line light source 20 is less than or equal to
Two endpoints of both sides are formed by angle (i.e. A1+A2+B1+B2) with the line at 20 center of LED line light source on the roof 10.
It should be noted that the greatest cross-section of spectrum part 11 refers to being carried out spectrum part 11 by a horizontal plane
Cutting is formed by section, which is parallel with LED line light source 20.It is corresponding, when spectrum part 11 is isosceles triangle,
Face where the bottom edge 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, on the one hand, LED
Linear light source 20 cannot pass through light splitting close to some light in the second part light and Part III light in centre of luminescence face
Two inclined-planes 111,112 in portion reflex to the first side wall 12 and second sidewall 13, but are directly reflected by roof 10, after reflection
Directional light cannot be formed, on the other hand, the light of part reflection may be stopped by LED line light source 20 forms dark space, eventually leads to
Spotlight effect is substantially reduced.
If the beam angle of LED line light source 20 is more than on the roof 10 in two endpoints with LED line light source 20 of both sides
The line of the heart is formed by angle (i.e. A1+A2+B1+B2), then some light is direct in the emitting beam of LED line light source 20
It is projected on the first side wall 12 and second sidewall 13 except roof 10, since the first side wall 12 can only be to one of spectrum part 11
Inclined-plane 111 reflect after light carry out secondary reflection formed parallel rays, second sidewall 13 can only to spectrum part 11 another
Light after inclined-plane 112 reflects carries out secondary reflection formation parallel rays.Therefore, for being directly projected to the first side wall 12 and
Light on two side walls 13 cannot form directional light after the first side wall 12 and second sidewall 13 reflect.
In view of this, in the present embodiment, LED line light source 20 is configured as small towards the projected area on 10 direction of roof
In or equal to the spectrum part 11 greatest cross-section area P, then on the one hand, can make LED line light source 20 close to shine
The second part light and Part III light of median plane 11 two, the portion inclined-plane 111,112 that can fully be split reflect respectively
It is parallel eventually by being formed after side the first side wall 12 and 13 secondary reflection of second sidewall to the first side wall 12 and second sidewall 13
Light, on the other hand, the light of reflection will not be stopped by LED line light source.
And whole light in the beam angle of LED line light source 20 be projeced into the roof 10 inner surface and spectrum part two
Inclined-plane 111,112, then whole light in 20 beam angle of LED line light source be divided into three parts；A part (light within the scope of B1, B2
Line) directional light reflected to form by roof 10；Another part (light within the scope of A1) be split portion 11 an inclined-plane 111 reflection
To the first side wall 12, then by forming directional light after 12 secondary reflection of the first side wall；A part of (light within the scope of A2) quilt again
Another inclined-plane 112 of spectrum part 11 reflexes to second sidewall 13, then by forming directional light after 13 secondary reflection of second sidewall.
Whole light of LED line light source 20 are subjected to reflecting condensation, finally formed light beam angle smaller thus, it is possible to realize.
It should be noted that as shown in figure 4, maximum two sides of distance in the luminous zone width direction of LED line light source 20
It is θ that edge point is formed by angle with the binding site line of 10 intersection of the spectrum part 11 and the roof respectively.
When the first reflection light L1, the second reflection light L2, third reflection light L3 and the LED line light source 20
When centre of luminescence face (faces L) is parallel, the light beam angle of the linear light source reflector is less than or equal to θ；When first reflected light
Line L1 and centre of luminescence face angle, the second reflection light L2 and centre of luminescence face angle and the third are anti-
Light L3 and centre of luminescence face angle is penetrated to be respectively less than or when equal to θ/2, the light beam angle of the linear light source reflector in θ and
Between 2 θ.
