Lighting device and method

A lighting device comprising:

• a first lighting strip;
• a second lighting strip, each of the first and second lighting strips comprising an elongate light emitting region, wherein the lighting emitting regions of the first and second lighting strips at least partially overlap in a region of overlap, and the first and second lighting strips are slidable relative to each other so that the region of overlap is adjustable, thereby to adjust the overall length of the lighting device,
• wherein each lighting strip has a first lighting emitting portion outside the region of overlap and a second light emitting portion in the region of overlap, wherein the combined light intensity per unit length of the second light emitting portions of the first and second lighting strips in the region of overlap corresponds to the light intensity per unit length of the first lighting portions of the first and second lighting strips,
• wherein the first lighting strip is driven off at the region of overlap, and
• wherein each lighting strip comprises an array of current driven lighting elements, wherein the first lighting strip comprises a sliding electrical connection coupled to the second lighting strip, which electrical connection bypasses the lighting elements of the first lighting strip in the region of overlap.
