An assembly light bar structure includes: a substrate, having at least one recess; a first conductive elastic element and a second conductive elastic element, disposed on the substrate and respectively located at two parallel sides of the recess; and at least one light-emitting element. The performance of the semiconductor device can be improved by controlling the stress separately for the active region and element isolation region. The organic Rankine cycle system is configured to receive heated fluid from the gasification system and to deliver cooled fluid to the gasification system. Each of the measured distribution values are divided by the reference intensity distribution, to cancel out influences due to fluctuations in the intensity distribution of the light beam. The tabs of the wire-cap are respectively arranged at an angle in first and second openings which are formed by the mesh of the wire-cap, and in which the tabs can disappear when mounting the cap on the neck.
