Abstract: A mixed reality rendering system includes a display device and a server, wherein the display device is at a user end, and the server is at a remote end. A native object is built in the server, wherein the native object has a virtual coordinate. The remote server converts a physical coordinate of the display device into a virtual coordinate. The server generates a virtual straight line based on the virtual coordinate of the display device and the virtual coordinate of the native object. A virtual streaming camera is generated on the virtual straight line based on a predetermined distance. The server renders a rendered object based on the virtual streaming camera.

Abstract: A blue light leakage-suppressing LED structure for emitting white light includes at least one LED chip, an encapsulation element, a light output lens, and an optical fuse coating formed of a thermosensitive material; or includes at least one LED chip and an encapsulation element formed of a mixture of an encapsulation material and a thermosensitive material; or includes at least one blue LED chip, a fluorescent powder layer, an isolation region, an optical fuse layer, and a light output lens. Thanks to the hue changing property of the thermosensitive material, the LED structure can reduce the intensity of its short-wavelength light component and its overall brightness significantly before reaching the L70 threshold, after passing which the LED structure will emit excessive blue light. Thus, the user is protected from overexposure to blue light and will be reminded to replace the LED structure when the LED structure is about to malfunction.

Abstract: A high-contrast miniature headlamp includes at least one light-emitting element, a first reflective surface, and a second reflective surface. The high-contrast miniature headlamp forms a virtual equivalent light source of the light-emitting element via the first reflective surface to increase the equivalent distance between the light source and the second reflective surface, thereby enhancing the contrast of the cutoff line of the beam pattern produced by the headlamp. The headlamp is so configured that, under the condition of maintaining its miniature design and reducing cost without compromising optical efficiency, a beam pattern with a high-contrast cutoff line (i.e., a high-contrast beam pattern) can be generated to significantly improve the safety provided by automobile lighting.
