摘要： This invention provides an aimer assembly for a vision system that is coaxial (on-axis) with the camera optical axis, thus providing an aligned aim point at a wide range of working distances. The aimer includes a projecting light element located aside the camera optical axis. The beam and received light from the imaged (illuminated) scene are selectively reflected or transmitted through a dichoric mirror assembly in a manner that permits the beam to be aligned with the optical axis and projected to the scene while only light from the scene is received by the sensor. The aimer beam and illuminator employ differing light wavelengths. In a further embodiment, an internal illuminator includes a plurality of light sources below the camera optical axis. Some of the light sources are covered by a prismatic structure for close distance, and other light sources are collimated, projecting over a longer distance.

摘要： A light-emitting module includes a light-emitting plate including a light-irradiating surface including a plurality of striped-pattern light-emitting units, and a reflecting member including a reflecting surface to reflect light emitted from the light-irradiating surface of the light-emitting plate toward a target surface of an object. Light at a peak luminous intensity in a light distribution in a first region of the light-irradiating surface is sent to a first region of the target surface via a first region of the reflecting surface. Light at a peak luminous intensity in a light distribution in a second region of the light-irradiating surface is sent to a second region of the target surface via a second region of the reflecting surface.

The main substrate includes a central part and a peripheral part that surrounds the central part. The plurality of light sources are each disposed on the central part of the main substrate. The plurality of lenses are disposed to correspond to the plurality of light sources respectively. The plurality of lenses apply optical effects to beams of light from the plurality of light sources respectively. One or more light reflection members are each disposed on the peripheral part.

摘要： Disclosed is a luminaire such as an LED downlight which is suitable for mounting in ceiling cavities of commercial environments. An example luminaire (200) comprises a light source (202) including an integral primary optic which is configured to transmit light toward a second optic (214). The second optic (214) is a lens configured to receive light from the light source (202) via the primary optic and transmit at least part of the received light toward a circular reflector (201). The circular reflector (201) is configured to direct light received from the second optic (214) away from the luminaire (204). A shape of the second optic (214) is interdependent with a shape of the circular reflector (201), and the shape of the second optic (214) and circular reflector (201) act in combination to transmit light away from the luminaire with a non-circular illuminance distribution (206).

摘要： An underwater diving light with efficient waterproof performance includes a top cover, a bottom cover, a light-emitting assembly and a special-shaped light-transmitting seal. A first installation groove is formed in the top cover. A second installation groove is formed in the bottom cover. The special-shaped light-transmitting seal includes a light-transmitting waterproof part, a first installation part and a second installation part. The first installation part, the light-transmitting waterproof part and the second installation part are all annular and connected in sequence. The top cover and the bottom cover are movably connected to form a light housing. The light-emitting assembly is arranged in the light housing. The underwater diving light has the advantages of strong waterproof and moisture-proof performance, diversified luminous forms and a dazzling effect.
