    摘要： A light emitting device (1) includes: three or more light emitting units (10, 20, 30) that individually include blue light emitting element, a wavelength range of the blue light emitting element accommodated in respective packages being different from each other. The light emitting device mixes output lights from the light emitting units (10, 20, 30) to output white light of a predetermined chromaticity. In an xy chromaticity diagram, the chromaticity of the output light from each of light emitting units (10, 20, 30) is located at a distance from the predetermined chromaticity. The difference between the chromaticity of the output light from each of the light emitting units (10, 20, 30) and the predetermined chromaticity is not greater than 0.04.

    摘要： A light emitting load driving apparatus includes a first switching element, a second switching element, and a gate driver, to drive first and second light emitting loads connected in series. The first switching element, when in an ON state, bypasses a current to be passed to the first light emitting load. The second switching element, when in an ON state, bypasses a current to be passed to the second light emitting load. The gate driver reduces at least one of an overshoot current caused when the first and second switching elements are simultaneously turned on and an undershoot current caused when the first and second switching elements are simultaneously turned off.

    摘要： A semiconductor substrate (21) of an IGFET (20) has drain regions (34) and (35), a p-type first body region (36), a p - -type second body region (37), an n-type first source region (38), and an n + -type second source region (39), and additionally has multiple pairs of trenches (31) that constitute an IGFET cell. A gate insulating film (25) and a gate electrode (24) are provided inside the trenches (31). A source electrode 23 is in Schottky contact with the second body region (37). A pn junction (43) between the second drain region (35) and the first body region (36) is exposed to one of the main surfaces of the semiconductor substrate. The first body region (36), the second body region (37), and the first source region (38) are also provided outside the trenches (31), and an n-type protective semiconductor region (40) is provided. The trenches (31) contribute to miniaturization of the IGFET and to lowering of the on-resistance. The reverse breakdown voltage of the IGFET can be improved by the reduction in contact area between the second body region (37) and the source electrode (23) to the outside from the trenches (31).
