LIGHT EMITTING DEVICE
A light emitting device includes a light emitting element, a frame, a first light-transmissive member, and a second light-transmissive member. The light emitting element includes an element upper surface from which a light is configured to be emitted, an element bottom surface opposite to the element upper surface, and an element lateral surface connecting the element upper surface and the element bottom surface. The frame is provided to surround the light emitting element to be opposite to the element lateral surface. The first light-transmissive member is provided on the element upper surface and the element lateral surface to contact the frame. The first light-transmissive member covers the element upper surface and the element lateral surface. The second light-transmissive member is provided on the first light-transmissive member.
CIRCUIT BOARD AND IMAGE FORMING APPARATUS
The circuit board has a surface mount LED with a lens on the circuit board. A conductive portion and remaining space in the periphery of the LED are covered with solid copper foil so that reflectance of light and a heat dissipation effect are enhanced. In addition, layer structures between the circuit board and an assembled component are the same between contact portions with the assembled component so that tilt in mounting the board is suppressed. As a result, the circuit board having mounted thereon the surface mount LED having high directivity can be accurately mounted on the assembled component, tilt of an optical axis can be suppressed, the reflectance of light from the LED can be increased, and the heat dissipation effect can be enhanced.
