  • Patent number: 9933605
    Abstract: A high-radiance broadband incoherent light source is provided by pumping a body formed from a doped material, such as a Ce:YAG crystal with one or more laser diodes. The laser diodes emit at a stimulus wavelength, which may be an absorption wavelength of the body, and the body fluoresces to emit broadband light in a wide emission band. The body is either disposed in, or forms a light-concentrating cavity, e.g., reflective surfaces, which may be dichroic surfaces, can be formed on or attached to the sides of the body to concentrate the emitted light. The light is captured by a light collector that is coupled to an output face of the body to produce a broadband illumination beam. One or more of the reflective surfaces forming the light-concentrating cavity may form a heat sink.

    Abstract: A lamp structure capable of switching light-emitting mode includes a carrying base (1), a light-guiding pillar (2), at least one LED (3), a fluorescent lamp (4) and a control module (5). The light-guiding pillar (2) is mounted on the carrying base (1). The LED (3) is correspondingly arranged to the light-guiding pillar (2). The fluorescent lamp (4) is fixed to the carrying base (1) and surrounds an external periphery of the light-guiding pillar (2). The control module (5) is used to switch power-on or power-off of the LED (3) and the fluorescent lamp (4). Accordingly, the fluorescent lamp (4) and the LED (3) are prevented from limiting light-emitting performance with each other, such that overall light-emitting efficiency and light-emitting performance of the lamp is enhanced.

  • Patent number: 8328363
    Abstract: An optical system includes a light source array, a dichroic mirror set, a light converting device and a light guide pipe. The light source array is used for emitting a first homogeneous light. The dichroic mirror set is disposed in a light path of the first homogeneous light and used for reflecting a part of the first homogeneous light to the light guide pipe, transmitting the remaining part of the first homogeneous light to the converting device. The light converting device is disposed in the transmitting light path of the dichroic mirror and used for transferring the first homogeneous light into a second, third homogeneous light. The dichroic mirror is further used for reflecting the second, third homogeneous light to the light guide pipe. The light guide pipe is used for mixing the first, second and third homogeneous light to obtain a white light.

  • Patent number: 8277078
    Abstract: A light emitting device includes: a light source unit which has a first and a second LED which are connected in parallel and emit lights of different colors, respectively. The lights of the first and the second LED are mixed to provide an emission light of the light source unit when an operating voltage is applied. The light source unit further has a resistor which is connected in series to the first LED to make forward current changing characteristics of the first and the second LED depending on change in the operating voltage to be different from each other, so that a required luminous flux-color temperature property, in which change in a color temperature of the emission light is made to depend on change in a luminous flux of the emission light, is obtained while the first and the second LED are turned on by applying the operating voltage.

  • Publication number: 20120116373
    Abstract: The invention relates to a light application apparatus (1) for applying light to an object (3). A light source (4) generates processing light (2) and sensing light (5), which are coupled into the object (3). A light detector (8) detects the sensing light (5) after having left the object (3), and a control unit (9) controls the light source (4) such that processing light (2) in a processing time interval and sensing light (5) in a sensing time interval are alternately generated. Since processing light and sensing light are generated alternately, the generation of the processing light and of the sensing light is decoupled, i.e. the processing light can be optimized for processing purposes and the sensing light can be optimized for sensing purposes. This allows improving the quality of sensing the object and, thus, the quality of controlling the application of light depending on properties of the object.

  • Patent number: 8132951
    Abstract: An endoscope system comprises first and second emitters, a fiber, and a controller. The first emitter emits illumination light to a photographic subject. The second emitter emits infrared light. Emission intensity of the second emitter is stronger than that of the first emitter. The fiber has a tip which moves in a spiral when viewed from the photographic subject during scan periods. The controller controls emission timing of the first and second emitters. Light emitted by the first and second emitters is cast from the tip of the fiber onto the photographic subject. The second emitter emits in a predetermined period of one of the scan periods, based on control of the emission timing, so as to shine infrared light with the second emitter to at least one part of the photographic subject, in order to perform marking.

  • Patent number: 8070323
    Abstract: A light fixture allows individual light bulbs to be arranged in compact fashion to maximize the number of bulbs per given area in the fixture. To facilitate replacement or exchange of the bulbs, the bulbs are mounted in alternating succession on a pair of separately movable supports, reorientation of which serves to remove the bulbs from the tight packed arrangement, to one in which the bulbs are sufficiently separated from one another to allow hand access for removal and installation of the bulbs. A distinct aspect of the aforementioned feature of the invention independent of the movable supports resides in the ability to utilize two of more of the fixtures to multiply the light produced. Advantageously, the fixtures can be arranged in direct physical series, side by side, or to form an array extending in orthogonal directions.
