A light assembly including a light holder is disclosed. The light holder includes a first ring configured for threaded engagement with a second ring to form a body defining an annular cavity to maintain a light element in a fixed position relative to a motorcycle or other vehicle. The light holder includes a spacer preconfigured for the light element that provides cushion and vibration protection between the body and the light element. Alignment markers defined along the body accommodate identification of one or more axial configurations of the first ring relative to the second ring for secure threaded engagement.

An adapter for changing LED light bulbs can have a threaded fitting for attachment to the pole of an existing light-bulb changer. The adapter has a body, preferably formed of a rigid material such as a rigid plastic. The body has multiple teeth to engage the spaces between the cooling fins of the LED light bulb. The light bulb can then be unscrewed from its socket and lowered using the pole and the adapter. A new light bulb can be placed on the teeth, raised, and screwed into the socket.

A method for producing a luminaire housing on an additive manufacturing system includes selecting a luminaire housing base shape from which a data file of a first convex polyhedral model is built, rescaling the first convex polyhedral model into a larger convex polyhedral model, filling the larger convex polyhedral model with multiple versions of the first convex polyhedral model, separating larger convex polyhedral shape model into structural unit shape, and providing the data file containing the structural unit shapes to the additive manufacturing system. In some implementations an interior volume of the larger convex polyhedral shape model can be cleared of portions of first convex polyhedral model. The method includes the additive manufacturing system producing one or more structural units based on the structural unit shapes described in the electronic data file. A non-transitory computer readable medium, and a luminaire housing including a light source are described.

An LED light fixture assembly includes an elongated first support member, an elongated second support member spaced from and substantially parallel to the first support member, and a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member. Each LED lighting fixture includes an elongated structural frame member having a substantially channel shaped support portion, and a mounting portion opposite the support portion. Each LED lighting fixture also includes a plurality of LED light modules secured to and positioned along the mounting portion, and a cover extending along and supported by the mounting portion. The cover is positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

An illumination module is provided that can be inserted into a receptacle that includes a wall and may be mounted on a support surface, such as a heat sink, and the illumination module include a cover and an LED assembly rotateably coupled to the cover. The LED assembly seats within the receptacle which causes terminals of the LED assembly to align with contacts on the receptacle. One of the cover and the receptacle can have a plurality of ramps and the other a plurality of shoulders. The cover can be rotated relative to the receptacle to cause the shoulders to slide relative to the ramps so as to direct the LED assembly into the receptacle. When the LED assembly is attached to the receptacle, the terminals on the LED assembly mate with the contacts on the receptacle.

A method for producing a tube lamp uses at least one leadframe. A leadframe is a flat structure which has two opposing surfaces extending substantially parallel and spaced apart by the sheet thickness. One or more stabilizing sections are applied to the leadframe. The leadframe is fastened with the stabilizing sections in a tubular housing of the tube lamp.

A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.

In one aspect, a luminaire is provided for illumination, in which the luminaire has a normalized spectral power distribution (SPD) curve for promoting human wellness, the normalized SPD curve having the following percentage areas for the following wavelength domains, the normalized SPD curve including spectral energy in a 620 nm to 640 nm region of the SPD curve ranging from 9.5% to 10.5% of a total of an area for a normalized SPD curve; spectral energy in a 640 nm to 660 nm region of the SPD curve ranging from 7.25% to 9.8% of the total of the area of the normalized SPD curve; spectral energy in a 660 nm to 680 nm region of the SPD curve ranging from 4.8% to 7.8% of the total of the area for the normalized SPD curve; spectral energy in a 680 nm to 700 nm region of the SPD curve ranging from 2.75% to 5.5% of the total of the area for the normalized SPD curve; and a remainder of spectral energy of the total normalized SPD curve is in a 400 nm to 620 nm region area of the SPD curve.

An apparatus includes a container, a plurality of lights and a circuit. The container may comprise an outer shell comprising a material configured to protect contents of the apparatus and an inner surface. The outer shell may be configured to open to enable the contents to be placed on the inner surface. A cavity may be formed within the container when the outer shell is closed. The plurality of lights implemented on the inner surface may each be configured to adjust a characteristic of light output in response to a signal. The circuit may be configured to generate the signal in response to an input. The circuit may be implemented between the outer shell and the inner surface. A reactive material of the contents of the container may be configured to change appearance in response to the characteristic of light.

The luminaire according to the invention comprises an inner space that is separated into a first section and a second section by a separating wall. While the first section is free and comprises at least one light source, an operating circuit for the light source and/or other components that form potential ignition sources and/or other components that may not be considered as ignition sources are arranged in the second section. The second section is provided with an open pored fill material. The separating wall comprises at least one opening that allows a flow connection between the two sections. The section of the inner space provided with fill material serves as pressure relief volume for the first section, in which the light source is arranged. The fill material can fill the section completely or partly.
