Example embodiments relate to compact luminaire heads. One example luminaire head includes a thermally conductive metal body that includes a plate-like portion, a tube portion, and at least one cooling fin. The plate-like portion extends in a longitudinal direction of the metal body and having a flat first surface and a second surface opposite the first surface. The tube portion extends in the longitudinal direction at the second surface. The at least one cooling fin extends away from the second surface adjacent to the tube portion. The luminaire head also includes at least one support substrate with a plurality of light emitting elements. The at least one support substrate is arranged against the first surface. The tube portion is shaped to receive in a first open end thereof a rigid cylindrical end portion of a mounting base, such as a pole for the luminaire head.

A heat-sink assembly is configured with two parts to grip a light-emitting element and produce a transverse force urging a surface of the light-emitting element toward a surface of the heat-sink assembly, which conducts heat away from the light-emitting element. Fastening mechanisms and a fulcrum inter-connect the heat-sink parts and produce the force that grips the light-emitting element. A configuration of the heat-sink parts creates a semi-enclosed space accessible through a gap. A configuration of elastomeric gaskets within the semi-enclosed space protects a portion of the space from intrusion of liquids or other environmental influences. Configuration of the heat-sink parts to form a recess in the heat-sink assembly provides protection of the light-emitting element from mechanical damage, and the recess may contain transparent materials that further protect the light-emitting element from detrimental environmental influences.

An LED strip includes a plurality of LED components and a wire set, the LED component comprising: an insulated main body, conductive terminals fixed on the insulated main body and connected to the wire set, and lighting an LED chip and a control unit configured on the insulated main body. The insulated main body has recessed notches. The wire set at least includes a first wire running through the notch, and the first wire is formed with a cut portion. When producing the LED strip in series connection, the LED components and the corresponding continuous wire can be soldered together directly by the means of SMT technique. Then, using a cutter and the preset notch, the wire can be cut at the position of the notch. In this way, the operation of SMT soldering for the LED strip can be completed quickly.
