  • Patent number: 9944031
    Abstract: Molded optical articles and methods of making them are disclosed herein. Optical articles comprise a photopolymerizable composition disposed on a major surface of a substrate. The photopolymerizable composition comprises: a silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation, and a platinum catalyst providing from about 0.5 to about 30 parts per million of platinum. The major surface imparts a positive or negative lens to the photopolymerizable composition. Optical articles also include those that have been photopolymerized using actinic radiation having a wavelength of 700 nm or less.

  • Patent number: 9755120
    Abstract: A light emitting device comprises an LED die, a dome lens encapsulating the LED die, the dome lens having a first outer curved surface, and a photopolymerizable composition disposed on the dome lens. The photopolymerizable composition forms a meniscus lens defined by a second outer curved surface and an inner curved surface, the inner curved surface being in contact with only a portion of the first outer curved surface. The dome lens and the meniscus lens in combination form an elongated dome lens.

  • Publication number: 20160306408
    Abstract: The present invention provides a power control device, a machine comprising the same and a power control method. The device is used for an integrated machine comprising a thin client and a display and comprises: a current detecting unit for detecting the current flowing through a port in the thin client connecting to the peripheral device; and a control signal generating unit for generating a control signal based on the intensity of the detected current to adjust the power consumption of the display and/or the thin client to maintain no increase in the power consumption of the integrated machine. The power control device, the machine comprising the same and the power control method of the present invention can be used to avoid low efficiency resulting from the power reservations for peripheral devices connected by a USB port.

  • Patent number: 7595515
    Abstract: Disclosed herein is a method of making a light emitting device comprising an LED and a molded silicon-containing encapsulant. The method includes contacting the LED with a photopolymerizable composition containing a silicon-containing resin having silicon-bonded hydrogen and aliphatic unsaturation and two metal-containing catalysts. One catalyst may be activated by actinic radiation, and the second by heat but not the actinic radiation. Polymerization of the photopolymerizable composition to form the encapsulant may be carried out by selectively activating the different catalysts. At some point before polymerization is complete, a mold is used to impart a predetermined shape to the encapsulant.

  • Publication number: 20090065792
    Abstract: A method of making a light emitting device is disclosed herein. The method includes providing an LED die and dispensing a photopolymerizable composition to form a photopolymerizable dome lens, wherein the photopolymerizable composition is optically coupled to the LED die. The photopolymerizable dome lens may be formed by the photopolymerizable composition using a single drop or a plurality of drops. In one embodiment, the photopolymerizable composition comprises a metal-containing catalyst and a silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation. The photopolymerizable dome is polymerized to form a polymerized dome lens. Light emitting devices prepared according to the methods are also described.
