Become the degree can being integrally incorporated in the multiple polaroids 132 formed a line.
Lens 116 can be cross section be circular (with reference to Fig. 4 and Fig. 5) and the rod lens (rod formed in long way
lens).Rod lens can configure along the length direction of LED module 120, and as shown in Figure 4, makes to be equivalent to spread light
The linear LED line light 122 becoming directional light form of LED light.
Certainly, the lens 116 that the present embodiment relates to are possible not only to be rod lens, as long as can make from LED element 112 defeated
The LED light line optically focused that goes out or be formed as directional light, it is possible to be any kind.
With reference to Fig. 5, LED line light 122 shape can be made by the interval a between regulation LED element 112 and rod lens
Become diffusion light or directional light.I.e., it is possible to as shown in Figure 4, reduce the interval between LED element 112 and rod lens, thus
Make all to be incident in rod lens 116 to form the LED line light of directional light form from the LED light line of LED element 112 output
122.Additionally, as it is shown in figure 5, the interval a between LED element 112 and rod lens 116 can be made slightly larger, so that from LED unit
A part (such as, 20%) in the LED light line of part 112 output is not incident in rod lens 116 but as diffusion light output,
Remaining LED light line (such as, 80%) is incident in rod lens 116 to form the LED line light 122 of directional light form.
Certainly, light source portion 110 can be formed for spreading the LED line light 122 of light form not use lens 116.Additionally, i.e.
The LED element 112 being arranged in same LED module 120, it is also possible to the mixed LED element 112 possessing lens 116 with
And do not possess the LED element 112 of lens 116.
Fig. 6 is that the LED line light 122 exemplifying the diffusion light form from LED element 112 output arrives alignment film 162
The schematic diagram of state.
With reference to Fig. 6, the LED line light 122 of diffusion light form can arrive alignment film 162.Irradiation overall width c can be formed
For the LED line light 122 of the diffusion light form below the twice of 126 width a in the middle part of irradiation collection, described irradiation overall width c is to shine
Penetrate intensity reach meansigma methods 5% till as the width in effective region.Thus, it irradiates with irradiating to remove in overall width c
Following relation is set up between the width b of remainder after 126 width a in the middle part of collection:
A+2b=c
2a≥c
Fig. 7 is the schematic diagram of the state exemplifying LED line light 122 by intersecting after polaroid 132.
When the LED line light 122 of directional light form is irradiated in 110, light source portion, although the directional performance of light improves, but
Accumulated light reduces, so that production declines.In order to solve these problems, as illustrated in Fig. 7, can make from multiple LED
The LED line light 122 of the diffusion light form of module 120 output intersects by after polaroid 132, thus increases shadow surface
Long-pending, particularly increase and be formed at the size of 126 in the middle part of the irradiation collection of central authorities.
Fig. 8 is to exemplify to form inclination angle in LED module 120 so that the signal of state that intersects of LED line light 122
Figure.
With reference to Fig. 8, it is characterised in that in order to concentrate diffusion light form from three LED modules 120 outputs further
LED line light 122, by the most inclined for the LED module 120 of both sides.Thereby, it is possible to increase irradiate collection in the middle part of 126
Area and concentrate light quantity.
Below, referring to figs. 1 through Fig. 2 and Fig. 9 to Figure 10, the polarization portion of the light alignment apparatus 100 that the present embodiment is related to
130 illustrate.
Fig. 9 is the top view in the polarization portion 130 exemplifying the light alignment apparatus 100 illustrated in Fig. 1, and Figure 10 is Fig. 9 institute example
The front view in the polarization portion 130 shown.

Straight bottom.
From the LED line light 122 transmission-polarizing sheet 132 tailing edge specific direction polarization of light source portion 110 output.Polaroid 132
Brewster polaroid or wire grid polarizers can be used.
Brewster polaroid is the polaroid being made up of multilayer dielectric film, utilizes Brewster's angle to be divided into p wave polarization
Component and s wave polarization component, it is possible to set high extinction ratio (polarization ratio).Wire grid polarizers can be by configuring therein
The gap of metal wire (grid) arbitrarily change wave band.Wire grid polarizers can be manufactured by the simple process that pattern shifts.
Multiple polaroids 132 form a line, and form the gap 138 of regulation each other.By shape between polaroid 132
Become gap 138, it is possible to rotate each polaroid 132 to regulate polarization direction.Two ends of polaroid 132 are provided with supporting member
134。
At the bottom configuration light obstructing member 140 in the gap 138 being not provided with polaroid 132, to prevent unpolarized LED straight line
Light 122 arrives alignment film.Light obstructing member 140 is formed by materials such as lighttight metals, and its width is more than the width in gap 138,
And it is more longer than polaroid 132.In view of LED line light 122 transmission, the width of light obstructing member 140 can be less than or equal to
4.5mm。
Light obstructing member 140 is positioned at the bottom of polaroid 132 and across predetermined distance, and this is to prevent polaroid 132
Impaired because of light obstructing member 140.
The bottom in polarization portion 130 is provided with protective glass plate 150.Protective glass plate 150 is used for preventing owing to irradiating alignment film
162 and the steam (vapor) that produces be attached on polaroid 132.Protective glass plate 150 can be by making LED line light 12 saturating
The materials such as the glass penetrated are formed.Protective glass plate 150 can be provided with one or more.
Figure 11 is the top view exemplifying the state before the polaroid 132 in polarization portion 130 is conditioned, and Figure 12 is to exemplify
Polaroid 132 in Figure 11 be conditioned after the top view of state.
With reference to Figure 11 and Figure 12, each polaroid 132 can rotate predetermined angular centered by center of rotation 136.In rotation
The heart 136 can be formed on the supporting member 134 for supporting polaroid 132 both ends rather than be formed at polaroid 132
Center.As shown in figure 11, when polaroid 132 arranges not along desired direction, can revolve centered by center of rotation 136
Turn each polaroid 132, thus polaroid 132 is adjusted to as shown in figure 12.
The center of rotation 136 of adjacent polaroid 132 is arranged on the end of opposition side.This is to prevent because of polaroid
Gap 138 between 132 is little and causes polaroid 132 to bump against.
