A high intensity LED based lighting array for use in an obstruction light with efficient uniform light output is disclosed. The high intensity LED based lighting array has a first concentric ring having a plurality of reflectors and light emitting diodes. The concentric ring has a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes. At least some of the first plurality of reflectors are adjustable relative to the position of the respective light emitting diode to produce a precise beam pattern from the light emitting diode.

A dental handpiece having a distal end including an attachment for assembly of a removable workpiece and a handpiece body intermediate a proximal end and the distal end. The handpiece extends in a substantially axial direction. A coupler is included having a cylinder portion and a supply-end portion, the cylinder portion being assembled into the handpiece extending in the axial direction toward the distal end. The cylinder portion includes at least one seal that interfaces with an interior of the body so as to isolate a portion of the body interior into at least one distinct chamber. The supply-end portion of the coupler extends from the proximal end of the handpiece body at an angle from the axis. The supply-end portion also includes a plurality of outlets, the at least one distinct chamber in fluid communication with one of the outlets of the plurality of outlets.

A coupler for coupling a light source to a fiber optic, comprising an adapter having a cavity for receiving the fiber optic, said adapter including pins extending in a direction perpendicular to the fiber optic's axis; a coupler body having an aperture for receiving the adapter, said aperture including a pair of through slots for receiving the pins, said body including interior pin sockets radially offset from the slots; a plate mounted within the coupler body; and biasing means urging said plate towards the aperture in the coupling body wherein when the adapter is inserted into the aperture of the coupler body, the adapter initially urges the plate in a direction away from the aperture, whereupon the adapter is rotated until the pins become aligned with and captured within the pin sockets allowing the plate to be urged in a direction back towards the aperture locking the coupler in place.

Improvements in material-to-material connections are provided. For example, metal-to-metal connections are improved, such as the interface connection between a dental handpiece bur tube () and a component such as a bearing (). At least one marking, such as a laser marking () is provided such that an amount of excavate material () is excavated from the marking (). When a component such as a bearing () is positioned upon the bur tube (), a portion of the excavate material () is physically impinged between the two components () filling any spaces or gaps therebetween.
