A light-emitting device includes: a substrate; a first light-emitting element row disposed on the substrate; a first wire disposed on the substrate and passing between two light-emitting elements adjacent in the first light-emitting element row; and a first bonding wire which has one end connected to one of the two light-emitting elements and another end connected to the other of the two light-emitting elements, and crosses over the first wire.

Light-emitting device and illuminating apparatus

A light-emitting device includes: a substrate; a first light emitter and a second light emitter which are disposed on the substrate; and a reflector which is disposed on the substrate and reflects light emitted by the first light emitter. The first light emitter, the reflector, and the second light emitter are aligned in stated order in a direction from a center toward a periphery of the substrate in a plan view. The first light emitter, the reflector, and the second light emitter decrease in height in stated order, the height being measured from the substrate.

Light-emitting device and illumination apparatus

A light emitting module includes a first light emitter that emits light having a first color temperature and a second light emitter that emits light having a second color temperature higher than the first color temperature. The first light emitter includes a first light emitting element and a first sealant. The first sealant seals the first light emitting element and includes a first wavelength converter that converts a wavelength of light emitted by the first light emitting element. The second light emitter includes a second light emitting element and a second sealant. The second sealant seals the second light emitting element and includes a second wavelength converter that converts a wavelength of light emitted by the second light emitting element. In a plan view, the first light emitting element has a surface area greater than a surface area of the second light emitting element.

Light emitting module and lighting apparatus

A light emitting device is provided. The light emitting device includes a substrate and a plurality of light emitting elements disposed on a major surface of the substrate. The substrate includes a reflector recessed in the major surface and surrounding at least a portion of the plurality of light emitting elements.

Light emitting device and lighting apparatus

A light-emitting apparatus includes: a ceramic substrate; a light-emitting element mounted on the ceramic substrate; a sealing member sealing the light-emitting element; a buffer layer formed on the ceramic substrate and surrounding the light-emitting element; and a dam member, at least a portion of which is on a top surface of the buffer layer and which is for blocking the sealing member. The dam member is formed in such a way that one end of the dam member which faces the sealing member and is closer to the light-emitting element than the opposite end of the dam member is in contact with the ceramic substrate while the opposite end is out of contact with the ceramic substrate.

Light-emitting apparatus, illumination apparatus, and method of manufacturing light-emitting apparatus

A light-emitting device includes a substrate, first LEDs and second LEDs mounted on the substrate, multiple wirings separately formed on the substrate, and a conductive member for connecting adjacent two wirings in multiple wirings for establishing series connection, parallel connection, or a combination of series and parallel connections of the first LEDs and the second LEDs. This achieves the light-emitting device that can support multiple different specifications, using a single type of substrate.

Light-emitting device and lighting apparatus using the same

A lighting device is provided in accordance with the present invention having reduced luminance and color unevenness. A plurality of solid-state light emitting elements are mounted on a base substrate. An optical member is further mounted on the substrate and arranged so as to cover light emitting surfaces of the light emitting elements, the optical member having a semicircular or semielliptical cross-sectional surface, and gutter-shaped in a longitudinal direction with respect to the substrate. A wavelength converting member covers the semicircular or semielliptical cross-sectional surface of the optical member, and is excitable by light from the solid-state light emitting elements to thereby emit wavelength-converted light. In various embodiments light diffusion members may be further distributed among the light emitting elements.

Lighting device topology for reducing unevenness in LED luminance and color

A light emitting device includes a plurality of solid-state light emitting elements; a board on which the solid-state light emitting elements are arranged in the form of an array; and a light distribution adjusting member for adjusting a distribution of lights outputted from the solid-state light emitting elements. The light distribution adjusting member is provided to commonly cover at least two of the solid-state light emitting elements, and includes an accommodating portion which accommodates the solid-state light emitting elements; a concave curved surface portion provided above light output surfaces of the solid-state light emitting elements and immediately above the solid-state light emitting elements; and a pair of convex curved surface portions which are provided in opposite sides of the concave curved surface portion, each of the convex curved surface portions being smoothly connected to the concave curved surface portion.
