摘要:
A dynamic optic includes at least one optic having a reservoir that is at least partially filled with a liquid and at least one light source disposed adjacent to the at least one optic. The upper surface of the liquid creates a total internal reflection surface that totally internally reflects light emitted by the at least one light source.

Transparent displays enable many useful applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light. Exemplary transparent scattering displays can be simple, inexpensive, scalable to large sizes, viewable over wide angular ranges, energy efficient, and transparent simultaneously.

Nanoparticles (NPs) may be used to transform the energy of harmful or less useful wavelengths into beneficial and more useful wavelengths of light for a multitude of purposes including, for example, promotion of photosynthesis, enhancing germination timing, enhancing bloom timing. In one embodiment, a greenhouse structure may include nanoparticles embedded in a glass or plastic panel, or may include nanoparticles disposed on a surface of such a panel, to alter the wavelength of available light to a desired wavelength in order to alter an event associated with plant life contained within the greenhouse structure. In another embodiment, nanoparticles may be applied directly to a part of a plant structure (e.g., leaves, stems, etc.) to alter a characteristic of light before receipt of the light by the plant.

A lava lamp display device comprising: a frame having a permeable vision window at a front surface thereof, and a lamp base and a projection light at a bottom of inner side thereof; a film-coated glass mounted on the vision window; a support bracket having at least one positioning hole thereon; a transparent bottle arranged in the positioning holes; and two reflection mirrors having a center serving as a reference to define the two symmetrical reflection mirrors, and both sides thereof inclined forward to form an angle θ being not parallel with the film-coated glass with 180° angle. After the filler of the transparent bottle is reflected repeatedly by the two reflection mirrors, the vision window shows shapes in an inward serial arrangement in the middle and unlimited extension on both sides, having effects of an illumination lamp device, an art decoration, and special visual in one unit.

摘要:
A radiation apparatus comprising a radiation source and a filter arranged in an optical path, said filter comprising two transparent filter discs which are arranged substantially in plane-parallel fashion relative to each other and which are held with their surrounding edges in a frame made of a material of good heat conduction, the filter discs and the frame defining a closed cavity which has provided therein a medium for selectively influencing the radiation spectrum. The frame is divided substantially in a direction transverse to the filter axis into first and second frame halves in such a manner that the one filter disc is arranged on the first frame half at the side facing the cavity and the other filter disc is arranged on the second frame half at the side facing the cavity.

A decorative light is disclosed. It includes a hollow base seat having a bulb seat on bottom portion for a bulb to fit in. The bulb is surrounded by a thermally insulated sheet which is spaced from the base seat and the bulb by a certain distance. A top end of the base seat is formed with a through hole in which a container is fitted. The container contains a liquid inside, which is dyed into a predetermined color and mixed with a plurality of polished plates. In use, the bulb radiates light and heat to the container to stir up the liquid, so that the polished plates are rolled to reflect the light and create a dynamic flickering effect.
摘要:
A liquid crystal (LC) display monitor has a high luminosity light source to provide good visibility in brightly lit areas. To prevent overheating of the LC screen and other components of the monitor, a two-phase cooler is provided. The cooler consists of two translucent, flexible bag-like containers, each conforming to a different side of the light source. A low-boiling point coolant within the containers absorbs heat from the light source and is partially vaporized. The coolant vapor travels from the containers into a condenser which is external to the monitor cabinet. The condenser draws thermal energy out of the coolant vapor, causing it to condense and return to the containers. The containers provide shock absorption to protect the light source, and the containers or the coolant may have light-scattering properties to provide diffusion of the light. Other alternatives include locating the light source within the containers or placing the container in contact with the LC screen rather than with the light source.
摘要:
A color changeable photo-decorative pencil torch which can be used not only for lighting but also as a toy. The pencil torch having liquid suspended light scattering members which when illuminated serve to scatter light in all directions. A movable multicolored filter is used to randomly vary the color of the light reflected by the light scattering members.
