<p>A light bar (10) may include a light head (12) with chip-on-board (COB) light emitting diode (LED) (14) and an optic component (28) mounted adjacent to the COB LED. The light bar may comprise short (56b) and long center modules (56c). The light bar may include a plurality of housing modules where each housing module includes a light head and a lens cover (58) having a top portion (62) that is substantially impervious to ultraviolet radiation, and a lens portion (64) extending downward from the top portion in generally opposing relationship with the light head. The light bar may include a circuit board (22) including a wire-to-board connector, and a light head including a wire-to-board connector mated with the wire-to-board connector on the circuit board to electrically connect the light head to the circuit board. The light head may include a holographic diffuser.</p> |
