An LED lighting fixture including a side access door and a compartment for housing electrical components required for operation of the LED fixture. The side access door secured to the compartment by a hinge structure, such that the side door is retained when in an open position.

A light management device comprising a protective light cap or cover is disclosed that provides for the blockage or allowance of designated wavelengths from being inadvertently being viewed by persons or being projected onto an external surface. The protective light cap or cover is pivotable connected to a lighting source to allow the cap to be positioned over the light source and moved away from the light source. The protective light cap is retained in an open position that allows the light source to be viewed, by one of a magnetic catch or a physical catch.

An LED lamp with an adjustable illuminating range is provided, including a lamp body. The lamp body includes a base, a lamp housing arranged on the base, and a light source assembly arranged inside the lamp housing. At least one side of the lamp housing includes an open structure allowing light from the light source assembly to emit. An adjusting mechanism is configured inside the lamp housing to adjust the illuminating range of the light emitted from the light source assembly. An emergence angle of the light source assembly or a size of the opening structure can be adjusted by the adjusting mechanism, thereby adjusting the illuminating range or an illuminating area of emitted light and meeting different user demands.

The vehicle lamp according to the present invention includes: a light source; a movable shade rotating in a front-back direction and switchable to a second position where some of light from the light source is blocked; a power section having a moving shaft moving in a horizontal direction; and a power-transmitting section transmitting a moving force of the moving shaft, as a rotary force of the movable shade. The moving shaft has an engagement groove with which the power-transmitting section is engaged. The power-transmitting section includes a second arm having an engagement section slidably engaged with the engagement groove. The engagement section includes a first engagement section engaged with the engagement groove and extending in the front-back direction, and a second engagement section that has a substantially linear shape, is engaged with the engagement groove and is connected to and bent with respect to the first engagement section.

A housing assembly for an illumination source such as a UV light where there is an enclosure formed by first and second releasably mateable housing shells and a bracket having a web, and first and second laterally extending flanges, the bracket being releasably connectable to said enclosure via the flanges, the enclosure having limited rotation relative to said bracket.

An LED lighting fixture (205) provided with a self-retaining side access door (220) to a wiring and driver compartment (245) of said LED fixture (205), and means for retaining said side access door (220) attached to said wiring and driver compartment (245) in an open configuration.

The present invention provides a sculpture bound within the volume of a polyhedron that when, rotated about an axis of rotation and positioned in the path of a directed light source, cast shadows of a predetermined and desired form onto a surface.

An optical structure for controlling distribution of light generated by a light source is described. The optical structure includes a primary optics disposed relative to the light source and configured to reflect light generated by the light source towards a target region. The optical structure also includes a secondary optics disposed and aligned relative to the primary optics. The secondary optics is configured to at least partially block light generated by the light source from illuminating a region outside the target region.
