A curing light device for curing a compound includes a housing and a tip structure configured to be removably coupled with the housing. A light emitting device operable for emitting light in a wavelength range suitable for curing a light curable compound is positioned at the distal end of the tip structure. Electrical components are positioned at the proximal end of the tip structure and coupled with the at least one light emitting device and are configured for engaging complementary electrical components positioned in the housing for providing power to the light emitting device. A portion of the tip structure extends beyond the proximal end of the tip structure and is configured to be received by a feature in the housing for physically aligning the tip structure in the housing and for aligning the electrical components. A power supply circuit is rechargeable and includes an ultracapacitor element.

An angle adjuster is configured by disposing a first driver for driving a horizontal rotation frame (horizontal direction rotator) to rotate in the horizontal direction and a second driver for driving a vertical rotation frame (vertical direction rotator) to rotate in the vertical direction on the horizontal rotation frame. This configuration can reduce the size of the angle adjuster and a lighting apparatus with the angle adjuster.

A tube that is at least partially optically transmissive. An LED mounted on a substrate is positioned in the tube and is operable to emit light through the tube when energized through an electrical path. Pins are in the electrical path. An electrical conductor electrically couples the pins to the electrical path, the electrical conductor is biased into engagement with an electrical contact on the substrate. The substrate may be secured to the tube by an adhesive. The substrate may be secured to the end caps and be suspended in the tube.

A light fixture includes an adjustable bracket, a pivot plate, a lamp bracket, and a lamp. The adjustable bracket is rotatable about a first axis. The pivot plate is connected to the adjustable bracket and rotatable about a second axis different from the first axis. The lamp bracket is removably connected to the pivot plate. The lamp is connected to the lamp bracket.

A light fixture can include a light housing and a light cartridge. The light cartridge can be configured to releasably and/or electrically connect to a portion of the light housing. In some embodiments, the light cartridge includes a collar movably connected to the cartridge and configured to rotate with respect to the cartridge. Rotation of the collar can facilitate attachment and/or release of the cartridge from the light housing. In some cases, the cartridge includes a releasable driver, one or more lenses, one or more beam reflectors, one or more diffusers, and/or other electrical and optical components.

A reading lamp includes a lamp top set having a tubular housing and a support column having a first end and a second end opposite the first end. The support column may include a column wall defining a hollow interior of the support column. A swiveling joint assembly may be positioned between and join the tubular housing and the first end of the support column, such that the swiveling joint assembly enables one or more of polyaxial and rotational movement of the tubular housing relative to the support column or the swiveling joint assembly.
