  • Patent number: 9696011
    Abstract: A light source is provided with extended persistence and reduced flicker characteristics by using a light capacitive filter. In general, a light source can include an illumination source which converts electrical energy into emitted light. The illumination source, however, is generally powered by an AC waveform, and the periodic variations inherent in the AC waveform may cause flicker in the emitted light. To reduce the flicker, a light capacitive filter is included in the light source to filter the light emitted by the illumination source and produce a light output with reduced flicker. In some examples, the light capacitive filter includes a medium persistence phosphor having a decay constant (or half-life) of between 1 milliseconds and 2 seconds.

    Abstract: The present invention relates generally to an illumination device used in dermoscopy. More particularly, the invention comprises an improved apparatus for enhanced imaging and illumination of the skin for medical examination and treatment. An array of LEDs encircle a magnifying lens assembly. One set of surrounding LEDs provides cross-polarized white light to aid in canceling the reflected light from the skin and creating less glare. Another set of surrounding LEDs provides non-polarized white light for traditional immersion fluid dermoscopy or for non-polarized viewing of the skin. A third set of surrounding LEDs provides polarized colored light, wherein the wavelength color is selected at a color wavelength that maximizes the viewing of skin pigment regions which is important for early detection of skin cancers and other skin diseases. In an embodiment of the invention the colored LEDs comprise orange light at a wavelength of 588 nm.

    Abstract: An illumination module includes a plurality of Light Emitting Diodes (LEDs) and a light conversion sub-assembly mounted near but physically separated from the LEDs. The light conversion sub-assembly includes at least a portion that is a polytetrafluoroethylene (PTFE) material that also includes a wavelength converting material. Despite being less reflective than other materials that may be used in the light conversion sub-assembly, the PTFE material unexpectedly produces an increase in luminous output, compared to other more reflective materials, when the PTFE material includes a wavelength converting material.

The base (110) has a light reflective surface (112) which faces towards the light exit window (104). The light reflective surface (112) has a base reflection coefficient Rbase which is defined by a ratio between the amount of light that is reflected by the light reflective surface and the amount of light that impinges on the light reflective surface. The solid state light emitter (154, 158) emits light of a first color range (114), comprises a top surface (152, 158) and has a solid state light emitter reflection coefficient R_SSL which is defined by a ratio between the amount of light that is reflected by the solid state emitter (154,156) and the amount of light that impinges on the top surface (152, 158) of the solid state light emitter (1154, 156).

    Abstract: A light emitting apparatus includes LED chips and a light condenser condensing the light emitted from the LED chips. The light condenser has a first opening functioning as an incident part through which the light emitted from the LED chips enters, a side surface function as a reflector that reflects the light having entered through the first opening, and a second opening functioning as an emission part that emits the light reflected by the side surface. A phosphor layer, which converts the wavelength of the light emitted from the LED chips and emits the wavelength-converted light, is formed in the first opening. The light condenser is arranged such that the phosphor layer is located on the light emission surfaces of the LED chips.

    Abstract: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., greater than 1,000 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate having conductors is then laminated over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. The light sheets may be formed to emit light from opposite surfaces of the light sheet, enabling it to be used in a hanging fixture to illuminate the ceiling as well as the floor.
