    • An illumination device including a light guiding element, a light emitting element, and a reflective element is provided. The light guiding element has a light incident surface, a light emitting surface, a first surface and a second surface. The light incident surface surrounds the light guiding element and is connected between the light emitting surface and the first surface. The first surface is connected between the light incident surface and the second surface so that the second surface is substantially opposite to the light incident surface. The second surface constructs a depression structure having a diameter gradually changed from the first surface towards the light emitting surface. The light emitting element surrounds the light guiding element to emit a light towards the light incident surface. The reflective element is disposed at least on the first surface.
    • 提供了包括导光元件,发光元件和反射元件的照明装置。 导光元件具有光入射表面,发光表面,第一表面和第二表面。 光入射表面围绕导光元件并且连接在发光表面和第一表面之间。 第一表面连接在光入射表面和第二表面之间,使得第二表面基本上与光入射表面相对。 第二表面构成具有从第一表面向发光表面逐渐变化的直径的凹陷结构。 发光元件围绕导光元件朝向光入射表面发射光。 反射元件至少设置在第一表面上。

    • An illumination device includes a light guide bar and light sources. The light guide bar includes a reflective layer, a light-emitting surface opposite to the reflective layer, and a light-incident surface connecting the reflective layer and the light-emitting surface. The light sources are beside the light-incident surface. Each light source includes a light unit and a lens. The lens is between the LED and the light guide bar and includes two opposite planar portions and two opposite arc-surface portions to surround a light-emitting axis. The planar portions are adjacent to each other and form a valley line aligned to the light-emitting axis at a junction of the planar portions. The planar portions respectively face the reflective layer and the light-emitting surface with respect to the valley line; thus, light provided by the LED is partially emitted toward the reflective layer and the light-emitting surface through the planar portions, respectively.
    • 照明装置包括导光杆和光源。 导光杆包括反射层,与反射层相对的发光面以及连接反射层和发光面的光入射面。 光源位于光入射表面旁边。 每个光源包括光单元和透镜。 透镜在LED和导光杆之间,并且包括两个相对的平面部分和两个相对的弧形表面部分以围绕发光轴线。 平面部分彼此相邻并且在平面部分的接合处形成与发光轴对准的谷线线。 平面部相对于谷线分别面对反射层和发光面; 因此,由LED提供的光分别通过平面部分朝向反射层和发光表面部分地发射。

    • A light guiding object for use in a lighting device is provided. The light guiding object includes a cylindrical body, a reflective layer, a transparent resin layer and a light-adjustable film. The cylindrical body has a light-entering surface and a bottom surface. The reflective layer is disposed on the bottom surface of the cylindrical body. The transparent resin layer is disposed on the light-entering surface of the cylindrical body. The light-adjustable film has a flat surface and an optical structure surface, wherein the flat surface is opposite to the optical structure surface and disposed on the transparent resin layer. A central part of the optical structure surface includes a first prism group. The first prism group includes a plurality of first prisms, wherein the apex angles of the first prisms are in a range of 120 to 170 degrees.
