A lighting system (100) including a plurality of LED-based light sources (102), where each of the light sources includes an optic holder (210) with an upper edge region (260). The arrangement of the optic holders within the lighting system results in gaps (220) between neighboring optic holders. The system includes a plurality of interstitial spacers (310) manufactured on or attached to the upper edge region of the optic holders, such that the interstitial spacers are arranged to substantially fill the one or more gaps.

A display device manufacturing method includes: preparing a substrate on which a plurality of light emitting elements are mounted; preparing a light shielding mask that is provided with a plurality of windows respectively transmitting light from the plurality of light emitting elements and that is warped so as to protrude towards an incident side of light from the plurality of light emitting elements; preparing a case in which a substrate is disposed; and screwing the light shielding mask to the case so that the light shielding mask is parallel or approximately parallel with respect to the substrate.

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.

An illumination device (e.g., an electric candle, etc.) generally includes a shell, a housing coupled to the shell, a first light source, and a pendulum supporting the first light source generally above the housing, wherein the pendulum is pivotally coupled to the housing and configured to move the first light source relative to the housing. The device also includes a flame-shaped head, where the first light source is disposed within the flame-shaped head, and a second light source arranged inside the shell and configured to illuminate the shell from the inside out. A printed circuit board assembly is arranged inside the shell for controlling operation of the first light source and the second light source.

A tool for installing and/or removing covers for light bulbs within a fixture is described. The tool may have a tube-shaped body with an installation end, a removal end, and a central axis along the tube-shaped body. A platform may be located within the tube-shaped body near the installation end. One or more frictional elements on an interior surface of the removal end may engage the cover. A handle attachment may be selectably and rotatably coupled to an exterior of the tube-shaped body between the installation end and the removal end.

According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, a light emitting diode (LED) mounted to the circuit board and configured to emit light, a lens disposed over the LED having a bottom surface facing the circuit board, a top surface opposite the bottom surface, and a lateral surface between the top and bottom surfaces, and an elastomer encapsulating at least part of the circuit board. The elastomer may not be in contact with at least part of the lateral surface of the lens so as to form a gap between the elastomer and the lateral surface of the lens.
