Abstract:
본 발명은 PMMA(Poly Methyl Methacrylate) 또는 PC(Poly Carbonat)로 제작된 것이고, 밑면 중 광 조사영역의 직하 지점에 위치하는 광원과의 사이 부분에 광원과 정해진 거리의 에어갭(Air-gap)을 형성하는 제1 요부가 형성되어 있고, 상기 제1 요부를 중심으로 좌우 양방향으로 멀어질수록 높이가 비례적으로 높아지는 적어도 1개 이상의 제2 요부가 형성되어 있는 것을 특징으로 하는 직하 방식 백라이트유닛용 도광판에 관한 것이다.
Abstract:
Waveguide elements, fabrication techniques, and arrangements thereof, are disclosed. The waveguide comprises in some embodiments an elongated hollow element having an elongated internal cavity and one or more electrically conducting layers plating at least internal walls of the elongated cavity. The elongated hollow element is implemented by a continuous unitary element made from a fibrous material impregnated with a resin material, thereby providing a lightweight unitary waveguide structure that substantially minimize, or preclude, leakage of electromagnetic energy along the waveguide length.
Abstract:
A light guide apparatus that can redirect light impinging on the apparatus over a wide range of incident angles and can concentrate light without using a tracking system and methods for fabrication. This apparatus uses conditions of total internal reflection and refraction near the critical angle for total internal reflection (near TIR) in order to trap light within the apparatus.
Abstract:
Foldable and folded light guide articles are described. Foldable light guide articles include a backing, a light guide disposed upon the backing and a prism disposed upon the backing adjacent to the light guide such that when the backing is folded about an axis between the prism and the light guide, a side of the prism is positioned adjacent to and aligned with an end of the light guide. Folded light guide articles include a light guide, a first prism and a second prism. The first prism is disposed adjacent to and aligned with an end of the light guide. The second prism is disposed adjacent to and aligned with the first prism with a low-index material separating the first prism and the second prism.
Abstract:
A general method is provided for electronically reconfiguring the internal structure of a solid to allow precision control of the propagation of wave energy. The method allows digital or analog control of wave energy, such as but not limited to 5 visible light, while maintaining low losses, a multi-octave bandwidth, polarization independence, large area and a large dynamic range in power handling. Embodiments of the technique are provided for large-angle beam steering, lenses and other devices to control wave energy.
Abstract:
A solution for fabricating a structure including a light guiding structure is provided. The light guiding structure can be formed of a fluoropolymer-based material and include one or more regions, each of which is filled with a fluid transparent to radiation having a target wavelength, such as ultraviolet radiation. The region(s) can be created using a filler material, which is at least substantially enclosed by the fluoropolymer-based material and subsequently removed from each region. The structure can further include at least one optical element integrated into the light guiding structure.
Abstract:
Fluorinated siloxane compositions, and methods of making and using the fluorinated siloxanes are disclosed. The polymers described herein may exhibit self-healing properties, a low dielectric constant, and a low refractive index. In some embodiments, a method of making a siloxane compound may involve contacting a silicon metal with a fluorinated compound to form a dichlorosilane compound, hydrolyzing the dichlorosilane compound to form a fluorinated tetrasiloxane compound, and contacting the fluorinated tetrasiloxane compound with a metal catalyst to form a fluorinated cyclic siloxane (D4) compound.
