Abstract: An illumination source disposed in a housing of a tool without the need for fasteners or snaps. The illumination source includes a number illumination elements, such as LEDs, disposed on a circuit board. A lens and the housing cooperatively direct light emitted by the illumination elements away from a user's eyes during use of the tool.

Abstract: A light ring assembly for a smart-home device may include a plurality of light-emitting diodes (LEDs) and a light guide, where the light guide may include a plurality of cutouts that receive the plurality of LEDs, and a plurality of transmissive sections between the plurality of cutouts. The light ring assembly may also include an output surface that receives light emitted from the plurality of LEDs through the plurality of transmissive sections, where the output surface is substantially circular. The light guide may also include a plurality of micro-lenses in the plurality of transmissive sections where a relative density of the micro-lenses increases as the transmissive sections extend away from the plurality of cutouts.

Abstract: An optic can manage light emitted by a light emitting diode. The optic can comprise a backside that faces the light emitting diode and a front side opposite the backside. The front side can be convex. The backside can have a central region that is adjacent the light emitting diode and that is either concave or convex. One or more grooves can extend peripherally about the central region. An injection molding system can produce optics in which the backside comprises the concave central region as well as optics in which the backside comprises the convex central region. The molding system can utilize one molding member shaped according to the front side of the optic. That molding member can be compatible with two other molding members that are shaped according to the different backsides of the optic. Thus, two different optic forms can be produced with three molding members.

Abstract: An omnidirectional lens is disclosed of the type which captures light from virtually all angles of incidence, and also emits light in all directions. Embodiments are specifically disclosed as a two-way lens that receives light beams from all directions of the compass and directs those light beams to a photosensor. The same two-way lens acts in a “beacon mode” to produce light beams from one or more LEDs, and to emit such light beams (again) in all directions of the compass. The emitted light beams can also be used to signal various functions as visible signals to users on a jobsite.

Abstract: A lamp unit which implements a source light source with a small number of light sources using a lens and a vehicle lamp apparatus including the same. The lamp unit includes an optical member, a base plate spaced from the optical member by a predetermined distance, and a spacer between the base plate and the optical member. The spacer supports an edge of the optical member, and a light source is disposed on the base plate. A lens is coupled to the base plate, and the lens covers the light source. The lens includes a connection portion contacting the base plate, and a reinforcement part contacting the spacer.

Abstract: A lamp optic (100) for a lamp includes a proximal end (104), a distal end (106) and a longitudinal axis (L). The proximal end (104) has a proximal inner side wall (112) linearly extending toward the distal end (106) and intersecting a proximal flat portion (114). The distal end (106) has a distal inner side wall (120) linearly extending toward the proximal end (104) and intersecting a distal flat portion (122). The distal flat portion length (LD) is at least 25 percent of the proximal flat portion length (LP). A lateral side (108) extends from the proximal end (104) to the distal end (106). The lateral side (108) has a first skirt region (124) and a second skirt region (126). The first skirt region (124) and the second skirt region (126) extend linearly and successively from the proximal end (104) to the distal end (106).
