By lightening the impact load to an electronic component and greatly promoting the load range, the adaptability to the electronic components is enhanced and the manned manual operation is eliminated, thereby improving the productivity and realizing unmanned operation. The vacuum-clamping nozzle unit comprises an automatically detachable vacuum-clamping nozzle (2) for vacuum-clamping the electronic component, a positioning section (3) for positioning the vacuum-clamping nozzle (2) in a rotating direction and a vertical direction, a pushing section (4) for urging said vacuum-clamping nozzle (2) downward by using fluid, a fluid pressure switching section for switching the urging force, a timing switching section for switching the timing of the urging force of said vacuum-clamping nozzle, and a pressure control section for controlling the load to a desired load. Switching the timing of the urging force can be made before or at the time of mounting the electronic component on an electronic circuit board.

A light source used for illumination provides favorable heat dissipation properties while suppressing the lowering of the efficiency of light emission. The light source includes a mount substrate, an LED 23 mounted on the mount substrate and a silicon resin mold containing phosphor particles that convert the wavelength of light emitted from the LED 25. The mount substrate includes a metal substrate 23 coated with a ceramic layer 24 containing light-transmissive or highly reflective ceramic particles.

A light source that restricts the heat accumulation in the phosphor. The light source includes: a substrate 5; LED elements D21, D22, D23, D41, D42 that have been implemented on a main surface of the substrate 5; projections 11 that have been formed in areas of the main surface of the substrate 5 in which any of the LED elements D21, D22, D23, D41, D42 have not been implemented; and a translucent sealing member 7 that has been formed on the substrate in a state that the LED elements D21, D22, D23, D41, D42 and the projections 11 are covered and sealed with the sealing member 7. The sealing member 7 includes a phosphor 13 that converts light from the LED elements D21, D22, D23, D41, D42 into light of a predetermined color. The heat conductivity of the projections 11 is higher than the heat conductivity of the sealing member 7.
摘要:
A bulb-type lighting source employs a light-emitting element in a structure that facilitates heat dispersal. The lighting source includes a first heat sink member mounted in a bowl shaped case supporting a power supply circuit. A mounting substrate is positioned in surface contact with a surface of the heat sink member and is capable of supporting a light-emitting unit. A globe covers the light-emitting unit to permit light emission. A second heat sink member has a surface in contact with a perimeter of the mounting substrate and offset from the light-emitting unit to provide a second part in surface contact with the first heat member to facilitate the release of heat.

A light-emitting device (1) includes a substrate (10), a light-emitting element (12) that is mounted on the substrate (10) and includes a luminous region (12b) and a nonluminous region (12a), and a phosphor layer (13) that is formed to cover the light-emitting element (12). The thickness of the phosphor layer (13a) located on the nonluminous region (12a) is smaller than that of the phosphor layer (13b) located on the luminous region (12b). The light-emitting device (1) can suppress nonuniform luminescent color.
