Description

Technical field

[0001] The present invention relates to a light-emitting device that converts light emitted by a light-emitting element using phosphors and emits it to the outside, and a lighting device using the same. Background technique

[0002] FIG. 18 shows a conventional light-emitting device 211 for housing a light-emitting element 214 such as a light-emitting diode (LED). As shown in FIG. 18, the light-emitting device has a mounting portion 212a on which the light-emitting element 214 is mounted at the center of the upper surface, and is mainly composed of the following devices: a base 212 formed with wiring conductors (not shown) The wiring conductor is composed of lead terminals or metalized wiring that electrically connect the mounting portion 212a and its periphery to the inside and outside of the light-emitting device; and the housing 213, which is adhesively fixed to the base On the upper surface of 212, a through hole for accommodating the light-emitting element 21...
