摘要： A light generator comprises a light conversion device and a light source arranged to apply a light beam to the light conversion element. The light conversion device includes an optoceramic or other solid phosphor element comprising one or more phosphors embedded in a ceramic, glass, or other host, a metal heat sink, and a solder bond attaching the optoceramic phosphor element to the metal heat sink. The optoceramic phosphor element does not undergo cracking in response to the light source applying a light beam of beam energy effective to heat the optoceramic phosphor element to the phosphor quenching point.

摘要： Disclosed are an electronic device and a control method thereof. The control method of an electronic device according to the disclosure includes: projecting, by the electronic device, a first test projection image including at least one marker of a first color while an external device projects a second test projection image including at least one marker of a second color; obtaining a captured image by capturing an image of projection regions on which the first test projection image and the second test projection image are projected while the projection region on which at least one of the first test projection image or the second test projection image is projected is changed; identifying the marker of the first color, the marker of the second color, and a marker of a third color in the captured image, the marker of the third color being displayed based on the marker of the first color and the marker of the second color overlapping each other; and identifying an overlapping region between the first test projection image and the second test projection image based on a result of the identification.

摘要： A projection device includes a heat source module, a heat storage module, and a heat dissipation connecting element. The heat source module is configured to generate a light beam. The heat storage module includes a storage tank and a heat storage material, and the heat storage material is filled into the storage tank. The heat dissipation connecting element connects the heat source module and the heat storage module. Heat generated by the heat source module is transferred to the heat storage module through the heat dissipation connecting element.

摘要： A projection apparatus and a control method thereof are provided. The projection apparatus includes a light source, an optical engine, a first sensor, and a processor. The light source provides a light beam to the optical engine. The optical engine converts the light beam into an image beam and projects the same out of the projection apparatus. The first sensor senses an ambient temperature. The processor is coupled to the optical engine, the light source, and the first sensor, records a projection time of the optical engine, selects a selected temperature range in which the ambient temperature is included from multiple temperature ranges according to the ambient temperature, and selects a selected driving program from multiple driving programs corresponding to the temperature ranges according to the selected temperature range to control the light source. A brightness of light beam is negatively related to the projection time.
