  • Patent number: 10334840
    Abstract: A bird anti-collision film prevents birds from flying into windows by disrupting visible habitat reflections that might appear on the outside of the windows. The anti-collision film blocks and/or absorbs light that may normally be reflected by a window and also actively scatters, and fluoresces light creating an active light disturbance. The disrupted light includes a light range highly visible by many birds but only partially visible by humans. A textured surface in combination with a fluorescent dye in the anti-collision film increases the intensity and range of the light disturbance. The anti-collision film may be attached to the inside of a window providing the unique advantages of easy inside window installation and insulation from external weather conditions.

    Abstract: A photonic device is manufactured by: (i) providing (e.g. by inkjet printing) an aliquot of a liquid crystal (LC) material; and (ii) depositing the aliquot onto the surface of a flowable material layer to form a liquid crystal deposit, the flowable material and the LC material being substantially immiscible. The liquid crystal deposit adopts a deformed shape relative to the shape of the aliquot due to interaction with the flowable material layer. This promotes alignment of the LC material. Incorporation of a laser dye allows the photonic device to function as a laser, which can be operated above or below threshold depending on the circumstances. The photonic device can also be used as a passive device based on the photonic bandgap of the aligned LC material.

  • Patent number: 9012945
    Abstract: LED dies, emitting blue light, are provided on a first support substrate to form a light emitting layer. A mixture of a transparent binder, yellow phosphor powder, magenta-colored glass beads, and cyan-colored glass beads is printed over the light emitting surface. The mixture forms a wavelength conversion layer when cured. The beads are sized so that the tops of the beads protrude completely through the conversion layer. When the LED dies are on, the combination of the yellow phosphor light and the blue LED light creates white light. When the LEDs are off, white ambient light, such as sunlight, causes the conversion layer to appear to be a mixture of yellow light, magenta light, and cyan light. The percentage of the magenta and cyan beads in the mixture is selected to create a desired off-state color, such as a neutral color, of the conversion layer for aesthetic purposes.

    Abstract: A method for fabricating an LED/phosphor structure is described where an array of blue light emitting diode (LED) dies are mounted on a submount wafer. A phosphor powder is mixed with an organic polymer binder, such as an acrylate or nitrocellulose. The liquid or paste mixture is then deposited over the LED dies or other substrate as a substantially uniform layer. The organic binder is then removed by being burned away in air, or being subject to an O2 plasma process, or dissolved, leaving a porous layer of phosphor grains sintered together. The porous phosphor layer is impregnated with a sol-gel (e.g., a sol-gel of TEOS or MTMS) or liquid glass (e.g., sodium silicate or potassium silicate), also known as water glass, which saturates the porous structure. The structure is then heated to cure the inorganic glass binder, leaving a robust glass binder that resists yellowing, among other desirable properties.

  • Patent number: 8821772
    Abstract: A method comprising injection molding a plastic part from a polymer formulation comprising an injection moldable thermoplastic and a fluorescent compound, wherein the fluorescent compound has a decomposition temperature that establishes a maximum processing temperature for the polymer formulation. The fluorescent compound will thermally decompose to generate gaseous products causing visible bubble formation in the surface of the plastic part in response to exposure to a processing temperature that exceeds the decomposition temperature of the fluorescent compound. If the plastic part was processed without exposure to a processing temperature that exceeds the decomposition temperature of the fluorescent compound, then any fluorescent compound within the plastic part will cause the plastic part to fluoresce in response to exposure to black light. A suitable fluorescent compound may be, for example, selected from oxalates, carbamic acids, carbonic acids, diazocarbonyl compounds, and combinations thereof.
