摘要:
An illumination apparatus includes an elongate chassis, a plurality of light emitting devices, a plurality of lenses, an elongate populated board, an elongate holding member, and a heat radiation member. The chassis includes a supporting portion supporting the opposite, longer-side ends of the populated board and a first engagement portion fitting and securing the holding member to the chassis. The holding member includes a plurality of second engagement portions fitting and securing each lens to the holding member and a resilient biasing portion resiliently biasing the longer-side ends of the populated board toward the supporting portion. The populated board is pinched and secured by the resilient biasing portion and the supporting portion and the heat radiation member is sandwiched and thus secured by the populated board and a bottom wall in contact with the populated board and the bottom wall.

An illumination apparatus includes lenses, a first casing that has a radiation plane provided with annularly arranged windows for attaching the lenses, respectively, independently, and that has an opening at a position opposite to the radiation plane, and a first substrate associated with each of the lenses and accordingly disposed. The first substrate has at least one light emitting device mounted thereon. The first casing includes a holding portion associated with each of the windows. The holding portion each permits the lens to be attached to the first casing from a side thereof having the opening and also restrains the lens from moving through the first casing toward the radiation plane, and when the lens is attached to the first casing, the lens has an optical axis in a direction having a predetermined angle relative to a center axis of the first casing.

An illumination device has a board, a plurality of light emitting elements that are mounted on the board, the plurality of light emitting elements being disposed such that a light irradiation direction of each light emitting element becomes substantially perpendicular to the board, and a plurality of lenses. Each of the plurality of lens is paired with one of the plurality of light emitting elements. A relative positional relationship between the light emitting element and the lens in each pair varies according to a position on the board in which the corresponding light emitting element is disposed.

The invention is a polyester resin mainly comprising a terephthalic acid component and a glycol component, wherein the fluorescence spectrum obtained by irradiating the polyester resin with excited light having a wavelength of 343 nm has a fluorescence intensity at 450 nm (B0) of 20 or lower. The resin makes it possible to efficiently produce a shaped article, especially a heat-resistant blow-molded article, that has excellent transparency and a moderate and stable crystallization rate and excellent heat-resistance dimensional stability, and is prevented from emitting fluorescence when irradiated with UV rays, and which is excellent in long-run continuous workability with no mold contamination, and which provides a wrapping material having excellent flavor retentiveness.
