Currently, there are many kinds of photoconductive tube lighting engineering as the foregoing description.But these technologies exist it is some not Foot.For example, for wedge-shaped light guide, if its length is too long, end may attenuate as a featheredge, and the featheredge will be difficult To manufacture or fix, and it is possible to fracture or rupture in use.On the other hand, by forming fine protrusions structure come real The photoconductive tube of existing light-guiding function then proposes high requirement to the precision of production and processing, so as to cause on the production cost of photoconductive tube It rises.

Accordingly, it is desirable to provide a kind of photoconductive tube, structure is relatively simple, easy to produce and process, and is easily installed solid It is fixed.

On the one hand, present disclose provides a kind of photoconductive tube, which includes: light input end;Light guide tube body, the light guide Tube body has substantially invariable thickness and width in its longitudinal direction;Light directing face;And light gasing surface;The light input end For one of two ends on the length direction of light guide tube body, light input end is provided with light source;Light directing face is light One interarea of catheter body, and light gasing surface is another interarea of light guide tube body, and opposite with light directing face;Wherein light Guide surface be it is smooth, multiple hollow three-dimensional light extraction structure settings close on light gasing surface in light guide tube body.Generally Ground, when the photoconductive tube of the disclosure is normally placed, light directing face and light gasing surface are its two face opposing upper and lower.

On the whole, the strip that the photoconductive tube of the disclosure can be linear can also be in curved strip.However, this Two kinds of shapes are only two unrestricted examples.Those of ordinary skill in the art will be understood that, not depart from the spirit of the disclosure And range, the cast body with essentially identical regular geometric shapes vertical section can be used as the disclosure in its longitudinal direction Photoconductive tube.Herein, " vertical section " of photoconductive tube refers to is somebody's turn to do with the perpendicular interception of the length direction perpendicular to photoconductive tube The resulting section of photoconductive tube.For example, as a non-limiting example, the vertical section of the photoconductive tube of the disclosure have rectangle, Positive direction, circle, ellipse, mushroom-shaped or the geometries such as trapezoidal.

In the disclosure, the thickness of photoconductive tube refers to, when intercepting the light guide with the perpendicular perpendicular to its length direction Guan Shi occupy the maximum vertical distance between the two o'clock of resulting vertical section or more two sides respectively;The width of photoconductive tube refers to, The maximum horizontal range between the two o'clock at left and right sides of theaforesaid vertical section is occupy respectively.When photoconductive tube is in curved strip When, to avoid the corner light leakage in the photoconductive tube excessive, the bending radius (i.e. its radius of curvature) of the photoconductive tube and its The ratio between thickness should be greater than 10: 1.

The photoconductive tube can be by many kinds transparent or semitransparent, optical property suitable material is made.These material packets Include polycarbonate (PC), polyacrylate (such as polymetylmethacrylate), polystyrene (PPE), glass and other Plastics with a high refractive index.

To avoid unnecessary optical scattering, the entire outer surface of the photoconductive tube of the disclosure need to pass through optical polish.Due to Those of ordinary skill in the art generally know the detail of optical polish, and details are not described herein for the disclosure.

In the disclosure, the light directing face of photoconductive tube is " smooth ", refers to that the roughness in the light directing face meets to light The requirement for being totally reflected and being oriented to.Since those of ordinary skill in the art generally know the specific thin of such light directing face Section, details are not described herein for the disclosure.

In addition to the above, another important aspect of the photoconductive tube of the disclosure be it includes light extraction knot Structure.In the disclosure, multiple light extraction structures included by photoconductive tube are located at photoconductive tube body interior.These light extraction structures tool Have hollow or for hollow three-dimensional structure, i.e., in these light extraction structures, the propagation medium of light is air.

In the disclosure, each hollow three-dimensional light extraction structures are different from its light directing face and light output in photoconductive tube Two side upper openings in face, but not in its light directing face and/or light gasing surface upper opening.This actually means that, in light guide On the length direction of pipe, there is only the hollow three-dimensional light extraction structures of a column.In other words, in photoconductive tube perpendicular to its length side To each vertical section on, at most there are the sections of a light extraction structures.Moreover, these hollow three-dimensional light extraction structures In the intrinsic depth of photoconductive tube, i.e., the face nearest away from light gasing surface of these light extraction structures between light gasing surface at a distance from, Less than the 20% of the vertical size (i.e. the thickness of photoconductive tube) perpendicular to its length direction of photoconductive tube.However, on the other hand, it should Depth is generally higher than 1mm.This is because the light extraction structures of photoconductive tube and its inside will become easy when the depth is less than 1mm It is destroyed in by external force.Preferably, which is 1mm to 2mm.

Preferably, the multiple hollow three-dimensional light extraction structures for including in the photoconductive tube of the disclosure have well-regulated geometric form Shape.For example, as a non-limiting example, these hollow three-dimensional light extraction structures can using common hollow cube, The geometries such as hollow cuboid, hollow cylinder, hollow class trapezoid block.In other words, when with the length side for being parallel to photoconductive tube To perpendicular intercepted when, the section of these hollow three-dimensional light extraction structures is square, rectangle, right angle ladder Shape or circle;When being intercepted with the perpendicular of the length direction perpendicular to photoconductive tube, these hollow three-dimensional light extractions The section of structure is square, rectangle, circle, ellipse or quadrangle.
