摘要

A light emitting diode cluster unit (10) suitable for use in outdoor display signs. A cluster (14) of LEDs on a circuit board (22) is housed in a first socket (26) open to its front and nested in an outer connector socket (16). Electrical connections (29, 30) are made from the rear of the first socket (26) via the connector socket (16) to a source of electricity. The connector socket (16) provides weather proofing and protects the circuit board (22) from torque. Moreover, the driver circuits of a display board into which the unit is connected may be shielded from ultraviolet rays. A tubular visor (12) may be provided to the front.
