A lamp is disclosed with a circuit board that is manufactured from a flexible material. The lamp may find particular use in a surgical or diagnostic environment. The flexible material allows the orientation of lamp elements to allow for a custom light beam. The flexible circuit board allows for interconnection between multiple lamp elements at different angles and rotation without having individual rigid circuit boards. Furthermore, the flexible circuit board may be mounted to a back panel, wherein the back panel is configured to act as a heat sink to dissipate heat generated, in operation, by the lamp element.

A portable indirect lighting apparatus includes first and second support structures. Each support structure includes a respective longitudinal light source having a linear array of light-emitting diodes (LEDs). A respective longitudinal lens is positioned proximate to each linear array of LEDs to receive and redirect the light emitted by the LEDs. A flexible reflector extends between the first and second support structure. The reflector has at least one diffusedly reflective surface. The reflector is configurable to an operational configuration with the diffusedly reflective surface positioned to receive the light redirected by the first and second longitudinal lenses. The reflector is configurable to a transportable configuration with at least a portion of the reflector wrapped around at least one of the first and second support structures.
