摘要： An expandable light bar system includes a plurality of light bar segments each having an elongated hollow body and a lighting unit. Each lighting unit includes a housing with a plurality of light emitting diodes that are electrically connected to either a subsequent lighting unit or a power source. The housing is secured onto a ridge that is located along the top surface of the elongated body. An expansion adaptor is positioned between two light bar segments and allows the overall length of the joined light bar segments to be adjustable. A spacer is positioned at the center of the adaptor and defines a minimum separation distance between the segments. A pair of endcaps are removably secured to one end of each of the light bar segments and are configured to engage an existing fluorescent high output socket within a light box to support placement of the joined segments.
