Led lighting apparatus with flexible light modules

A lighting instrument, comprising:

• a street light housing;
• and
• a plurality of lighting modules disposed within the street light housing, each lighting module being individually detachable from the street light housing, wherein each of the lighting modules includes:
• a thermally conductive substrate;
• a plurality of light-emitting diode (LED) devices located on the substrate;
• a metal cover disposed over the substrate, wherein the metal cover includes a plurality of openings that are each aligned with a respective one of the LED devices;
• and
• a thermal dissipation structure coupled to the substrate.

A street light, comprising:

• a base;
• a lamp post coupled to the base;
• a lamp head coupled to the lamp post, wherein the lamp head includes:
• a housing;
• and
• a power module;
• and
• a plurality of light modules disposed within, and each individually detachably coupled to, the housing, wherein each lighting module includes a plurality of light-emitting diodes (LEDs), a heat sink thermally coupled to the LEDs, and a thermally conductive cover having a plurality of openings each aligned with a respective one of the LEDs.
