Abstract: A luminaire (100) has an elongate tubular shell (1) and an elongate internal chassis (2) within the shell dividing space within the shell between a first compartment for electrical components and a second compartment for optical components (7, 6). The luminaire has a sealing cap (3, 4) at each end, and at least one of which supports an auxiliary active component for an application such as emergency lighting or car parking management. The shell (1) has features 1(a) for desired optical properties. The only seals are at the ends, between the end caps and the shell, and these are via sealing rings (17).

Abstract: A control device for use on a working surface includes a bottom housing configured to be placed on the working surface; a top housing coupled with the bottom housing, the top housing including at least one key; an actuator disposed between the bottom housing and the top housing and coupled with the key; a switch disposed between the bottom housing and the top housing, wherein the switch is activated via application of an actuation force to the key; and an adjustment means configured to enable a user to adjust the actuation force required to activate the key.

Abstract: A roller for a control device includes a roller wheel having an outer portion formed of metal and a corrugated surface; a pivot arm configured to pivot in a first direction to contact the corrugated surface and to pivot in a second direction to move away from the corrugated surface; and energy driven means configured to pivot the pivot arm.

Abstract: A system and method of manufacturing directed to an attachment system for use in an optical device. The attachment system mechanically couples a light source to an illumination lens using an attachment device. The attachment device can be an auto-centering device for reducing positional errors in a light beam emitted from the light source.

Abstract: An input device comprises a housing, and a user-movable roller having an exposed portion exposed from the housing. The roller is rotatable in a first rotational direction to generate first rotational signals. A first user-manipulable button is exposed from the housing for contact by a user and configured to simulate rotation of the roller in the first rotational direction and to generate the first rotational signals when pressed and maintained in a pressed position. In some embodiments, the roller is rotatable in a second rotational direction opposite from the first rotational direction to generate second rotational signals. A second user-manipulable button is exposed from the housing for contact by the user and configured to simulate rotation of the roller in the second rotational direction and generate the second rotational signals when pressed and maintained in a pressed position.

Abstract: A control device includes a roller configured to rotate and tilt; a roller support coupled to the roller, wherein the roller is configured to rotate relative to the roller support; the first hinge disposed adjacent to a first end of the roller support; and a second hinge disposed adjacent to a second end of the roller support, wherein the first end and the second end are substantially opposite ends of the roller support, the second hinge is above the first hinge, and the first hinge and the second hinge are configured to provide tilting support for the roller and roller support.
