Abstract

The invention relates to a light source unit and an illumination device. The light source unit includes a substrate and a reflective body. The substrate includes a plurality of light-emitting elements mounted thereon. The reflective body includes a plurality of incident openings each corresponding to one of the plurality of light-emitting elements, an output opening to which light that has passed through the incident opening is output, and a plurality of reflective surfaces that expand from the incident opening toward the output opening. Reflective surfaces included in the plurality of reflective surfaces and positioned on an outermost side are provided to be adjacent to one another, and an angle is set so as to prevent reflective light of light emitted from the light-emitting elements from traveling toward an outer side in a reflective surface formed on the outer side. The invention also provides the illumination device using the light source unit.

Description

technical field [0001] The present invention relates to a light source unit (unit) using a light emitting element such as a light emitting diode (Light Emitting Diode, LED), and a lighting device using the light source unit. Background technique [0002] In recent years, lighting devices in which a light emitting element such as an LED is mounted on a substrate and the light emitting element is used as a light source have been developed. For example, the lighting device is as Figure 8 Shown is a down light recessed into the ceiling. First, the outline of the downlight 101 will be described. [0003] The downlight 101 includes a thermally conductive cylindrical body 102, a decorative frame 103 mounted on the cylindrical body 102, a substrate 104 also mounted on the cylindrical body 102 and equipped with an LED 110 as a light emitting element, and housed in the cylindrical body 102. A power supply unit 105 , a reflector 106 , and a translucent cover 107 disposed in front of...
