A lighting device includes a light emitting element; a first lens that receives light emitted from the light emitting element and emits first emission light; and a second lens that receives the first emission light and emits second emission light. The first lens has a first emission surface emitting the first emission light, the first emission surface having a convex shape protruding in a Z direction.

Lighting device

An illumination apparatus includes a light-emitting element, a first lens, and a second lens. A first incident surface of the first lens faces the light-emitting element, and guides a light beam from the light-emitting element to a radiation port. A second incident surface of the first lens guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens. A first reflection surface of the first lens reflects a light beam from the second incident surface to guide the light beam to the radiation port.

Illumination apparatus

An illumination device has plural LED light sources, a reflection plate that has plural openings facing the respective LED light sources, and plural lenses that faces the respective openings and that guides light emitted from the plural openings in a direction vertical to the openings. The reflection plate is placed between the plural LED light sources and the plural lenses, and converges the light emitted from the plural LED light sources.

Illumination device

A light guide plate includes: an annular part formed in an annular shape along an element array of multiple light emitting elements; and an annular inner part formed on an annular inside of the annular part continuously with the annular part. The annular part includes: an element array-facing part which is a part facing the element array and which has an incident surface to allow light emitted from the light emitting elements to enter; and a first reflecting part which is a part located closer to the annular inner part than the element array-facing part, and which has a reflecting surface for reflecting the light entering from the incident surface toward the annular inner part. The first reflecting part includes a first light scattering region having a light scattering treatment applied thereto.

Illuminator

A synthetic resin globe for a light-emitting device is produced by molding an intermediate product with an injection molding die, softening the intermediate product in a heating apparatus, expanding it with compressed air in a die to form a globe shape, transferring a concavo-convex shape formed in a core of the injection molding die to form a concavo-convex shape on an inner wall of the intermediate product, so that the concavo-convex shape can be easily formed into a desired shape in a lower part of an inner wall of the globe.
