LIGHT-EMITTING DEVICE, ILLUMINATING APPARATUS, AND DISPLAY APPARATUS

摘要

The invention provides a light-emitting device which is capable of applying light to a display panel with uniformity in brightness and can be made lower in profile. A light-emitting device (11) includes an LED chip (111a), a base support (111b) which supports the LED chip (111a), and a lens (112) disposed in contact with the LED chip (111a) so as to cover the LED chip (111a) and the base support (111b). The lens (112) has first curved sections (1122) which reflect light that has reached a top surface (112a) so that the reflected light is emitted from a side surface (112b), and second curved sections (1123) which refract light that has reached the top surface (112a) to outside so that the refracted light is emitted from the top surface (112a).

主权项

1. A light-emitting device for applying light to an illumination object, comprising:
a light-emitting element that emits light; a base support that supports the light-emitting element; and a columnar optical member disposed on a light-emitting surface side of the light-emitting element, reflecting or refracting light emitted from the light-emitting element in a plurality of directions, the columnar optical member having a top surface which faces the illumination object and is shaped so as to have a recess at a center thereof, the top surface of the columnar optical member including a first region which reflects light emitted from the light-emitting element and travels in an interior of the columnar optical member so that the light exits from a side surface of the columnar optical member to outside of the columnar optical member, and a second region which refracts light emitted from the light-emitting element and travels in the interior of the columnar optical member so that the light exits from the top surface.
