A method and apparatus for collecting and projecting light into a specified target illuminance. A lens may be mounted or otherwise paired to a carrier to form a lens/carrier combination, which may then be mounted to a printed circuit board containing a light emitting diode (LED). The lens/carrier combination may establish an optimum optical relationship between the LED and the lens, such that a predetermined photometric distribution of the LED is collected by the lens, while the remaining photometric distribution of the LED is rejected by the carrier. The photometric distribution of neighboring LEDs, if any, may also be rejected by the carrier so that interference light may not be allowed into any lens. A diffuser may then spread the specified target illuminance into a beam pattern that may be compliant with specific standards (e.g., Department of Transportation or Economic Commission for Europe standards).

The embodiment of present invention discloses a press fixture, including: a carrier board; a power unit and a pressing unit attached on the carrier board and arranged at a certain distance with each other; a retractable unit and a pushing block, one end of the retractable unit being fixedly connected to the power unit and the other end of the retractable unit being fixedly connected to the pushing block. The power unit drives the retractable unit to retract, so that the retractable unit brings the pushing block to move between the power unit and the pressing unit, for pressing the first piece to be pressed and the second piece to be pressed located between the pushing block and the pressing unit. The press fixture according to the embodiment of present invention reduces the work force and the work intensity of the operators.

According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, an LED mounted to the circuit board that is configured to emit light with an angular CCT deviation, a lens assembly mounted to the circuit board over the LED and configured to receive the light emitted from the LED and reduce the angular CCT deviation of the light received from the LED to make a color temperature of the light received from the LED more uniform, and an elastomer encapsulating at least part of the circuit board that is separate and distinct from the lens assembly.

A lighting device assembly includes a light source attached to a heat sink member, a first optic device and a mounting housing configured to be secured in or to a ceiling, wall or other object, and to hold the heat sink member. A second optic device including a second optic member is configured to receive light emitted in a first direction from the light emitting surface of the first optic device and to emit light in a second direction that is transverse to the first direction. A connection mechanism selectively connects the second optic device to the mounting housing, for selective disconnection from the mounting housing.

A lighting system can comprise an edgelit panel, for example a lightguide that may have a panel or slab shape with an edge that receives light from an array of light emitting diodes extending along the edge. The lightguide can guide the received light towards an opposing edge of the lightguide and gradually release light to provide illumination. An optic can manage light that reaches the opposing edge of the lightguide, for example via softening, spreading, concentrating, or diffusing the light. The optic can be mounted to or integrated in the opposing edge of the lightguide.
