摘要： To improve the illumination efficiency of hand-held illumination devices, this invention proposes a new illumination device having the "rolling" function, which is capable of illuminating the target area on which a user is currently focusing and rolling the illuminated area as the user is reading forward or backward. The illumination device comprises two pluralities of lighting elements, an illuminating body and a controller. The controller can control one plurality of lighting elements to emit light to illuminate a part of the illuminating body, which can further deflect the light to a part of the surface of the target.

摘要： The invention discloses a light guide apparatus which comprises a light guide (1). The light guide (1) comprises a plurality of diffraction gratings (2) on a first surface of the light guide (1), wherein each diffraction grating (2) has a pre-set pitch and is configured to diffract a portion of light emitted from a corresponding light source to one side of the light guide (1). As the plurality of diffraction gratings (2) is placed on the first surface of the light guide (1) facing the light sources, the light guide apparatus is more robust to damage and fingerprints.

摘要： An X-ray detector (1) includes a light detection arrangement (3) such as a CMOS photodetector, a scintillator layer (5) such as a CsI:Tl layer, a reflector layer (9) and a light emission layer (7) interposed between the scintillator layer (5) and the reflector layer (9). The light emission layer (7) may include an OLED and may have a thickness of less than 50 μm. Thereby, a sensitivity and resolution of the X-ray detector may be improved.

摘要： The present invention aims to provide a light guide apparatus based on diffraction gratings. The apparatus comprises a light guide plate (11) comprising a first diffraction grating (13) located on a first surface of or inside the light guide plate (11); a first light source (12), coupled to a first side of the light guide plate (11); wherein the first diffraction grating (11) is configured to extract the light generated by the first light source (12) from the first surface of the light guide plate (11). Since the first diffraction grating (13) is invisibly small, users hardly notice any change of the light guide (11). When the light guide apparatus of the present invention is used as a book reader, the dark area produced when lifting the book reader in a direction away from the objects to be read is smaller than that of existing light guide apparatus based on microstructures, since the light exit angle is relatively small when using a diffraction grating.

摘要： The invention relates to a Luminescent Solar Concentrator system (400) and a method for collecting and concentrating external light, particularly sunlight (λ
1 , λ
2 ). The external light is collected by a luminescent converter component (410) having a thickness D and a ratio R = a
x /a
c between the absorption coefficient ax for sunlight and the reabsorption coefficient ac for luminescence light. Due to the luminescent material comprised by said converter component (410), at least a part of the external light is converted into luminescence light. Moreover, light propagating within the converter component (410) is extracted from it at light extraction sites (EX) having distances W ≤ 0.1⋅R⋅D from each other. Light extraction components may for example comprise slanted mirroring surfaces (414) and/or optical elements in contact to the converter component.
