  • Publication number: 20130076364
    Abstract: A battery detection method detecting if a voltage to be tested falls within a voltage range between a highest voltage of a rechargeable battery and a highest detection voltage. If the voltage to be tested is less than the highest detection voltage, further determine if the voltage to be tested reaches a target voltage within a test time period. If the voltage to be tested reaches the target voltage after the test time period expires, determine that the voltage to be tested is from a rechargeable battery. If the voltage to be tested reaches the target voltage within the test time period, determine that the voltage to be tested is from a non-rechargeable battery. Accordingly, the battery detection method can easily detect if a voltage to be tested is from a rechargeable battery.

  • Publication number: 20090127096
    Abstract: A method for forming a corrugation multilayer is provided. A periodic substrate is obtained, and then a corrugated reshaping layer is formed on the periodic substrate. The corrugated reshaping layer may be formed by an ion beam sputtering system and a bias etching system. Afterward, the following steps a and b are performed repeatedly. In step a, a first capping layer is formed on the periodic substrate by the ion beam sputtering system. In step b, a second capping layer with a corrugation appearance is formed on the first capping layer by simultaneously depositing by the ion beam sputtering system and trimming by the bias etching system. The autocloning corrugation multilayer can be carried out according to this method.

  • Patent number: 7495375
    Abstract: A polarized light emitting device including a first reflector, an LED chip, a fluorescent layer, a second reflector and a polarizer with corrugation structure is provided. In the polarized light emitting device, the LED chip emits a first light (e.g. ultraviolet light) confined within a resonant chamber configured by the first reflector and the second reflector, therefore the fluorescent layer can be adequately illuminated by the first light, thus emitting more second light (visible light) and improving the electro-optical transforming efficiency. The second reflector is adapted for reflecting the first light, and allows most of the second light to pass through. The polarizer with corrugation structure disposed outside the resonant chamber is adapted for efficiently polarizing the second light.

    Abstract: A light emitting diode with a quasi-omnidirectional reflector comprises a luminescent gel which is coated surrounding a UV light LED chip and a quasi-omnidirectional reflector which is disposed above the luminescent gel. The quasi-omnidirectional reflector is a wild angle cut-off filter which is made by a cooperation of a method for an optical film coating and a property of a total reflection. According to the property of the optical film coating, a light with an incident angle smaller than a critical angle can be reflected, such that a light form the LED chip is confined in the luminescent gel, which makes the luminescent material is excited as much as possible for improving the conversion efficiency of the light. When this LED chip co-works with different colors of the luminescent gels, different colors of lights are excited and produced.
