摘要: An assembly structure comprises a first component, a second component, and at least one assembling module. The assembling module is mounted at the second component and comprises an elastic element and at least one engaging element, which is moveable along an abutting direction. The elastic element pushes the engaging element along the abutting direction, such that the engaging element extends out from the second component and abuts against at least one matching portion of the first component along the abutting direction to detachably assemble the second component to the first component along an assembling direction, which is nonparallel to the abutting direction. A lighting device comprises the assembly structure, at least one light guide plate mounted at the first component, and at least one light-emitting unit, which is mounted at one of the second component and the engaging element of the assembling module and faces the light guide plate.

摘要: A light module includes a first light emitter, a second light emitter, a third light emitter, and a controller. The first light emitter is configured to emit a first light having a first peak wavelength in a visible range, the second light emitter is configured to emit a second light having a waveform having a second peak wavelength higher than the first peak wavelength, and the third light emitter is configured to emit a third light having a third peak wavelength that is shorter than the first peak wavelength. The controller is configured to control the first light emitter, the second light emitter, and the third light emitter to generate a first light pattern and a second light pattern. The first light pattern comprises a first light spectrum and the second light pattern comprises a second light spectrum including at least one more peak wavelength than the first light spectrum.

摘要: The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 μm to 50 μm), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.

摘要: An ultrasonic touch sensor includes a housing having a package cavity; an ultrasonic transmitter arranged within the package cavity, and configured to transmit an ultrasonic transmit wave; an ultrasonic receiver arranged within the package cavity, and configured to receive an ultrasonic reflected wave produced by a reflection of the ultrasonic transmit wave and generate a measurement signal representative of the ultrasonic reflected wave; a measurement circuit arranged within the package cavity and coupled to the ultrasonic receiver, and configured to detect a touch or a non-touch based on the measurement signal; a light source configured to produce an activating light; and a coupling medium that fills or at least partially fills the package cavity. The coupling medium includes a luminescent material that is configured to be activated by the activating light to produce a backlight that is emitted from the package cavity.

摘要: An LED retrofit lamp for a projection headlight system comprises a heat dissipating body portion and a substantially rectangular substrate. A first LED group is mounted on a first surface of the substrate and a second LED group is mounted on a second surface. A support bracket is configured to engage longitudinal sides of the substrate to mechanically support the substrate in alignment with a central optical axis of the headlight system so that light emitted by the first and second LED groups parallel to the first and second surfaces illuminates corresponding top and bottom segments of a cooperating reflector with sufficient intensity for projection headlight system to form a beam having substantially homogenous light intensity.

摘要: A light module for a lighting device of a vehicle is disclosed having at least one illuminant and a light-guiding body which is suitable and destined for guiding radiation emanating from the illuminant and coupled into the light-guiding body to a light exit surface of the light-guiding body, and having at least one rear wall apparatus which is arranged at least in certain areas in the beam path of ambient radiation incident from externally through the light exit surface of the light-guiding body into the light-guiding body. The rear wall apparatus has at least one first rear wall region and at least one second rear wall region, wherein the at least one first rear wall region and the at least one second rear wall region differ from one another in terms of reflection and/or absorption properties, for example with regard to the ambient radiation.
