Abstract

There is provided a light-emitting module which makes it difficult to sense glare and which suppresses the temperature rise of light-emitting diode chips and has a cost advantage. The light-emitting module is provided with a base body (11) formed with a non-metallic member having a thermal conductivity of 1 W / mk or less. In the base body, a plurality of LED chips (12) are spaced 10 to 30 mm apart from each other, and their junction temperature when they are normally lit is preferably set at 90 DEG C or less. A translucent sealing member (13) covering an area between the adjacent light-emitting diode chips (12) is provided.

Description

technical field [0001] The invention relates to a light-emitting diode (Light-emitting diode) as a light source (light module) and a lighting device. Background technique [0002] In recent years, light-emitting diodes have been used as light sources of large lighting devices used in offices, general lighting, etc. due to their improved luminous efficiency, and have been gradually commercialized. In this lighting device, a chip on board (COB) module capable of densely arranging a plurality of light emitting diodes is often used. [0003] For example, there is a ceiling direct-mounted lighting device or a suspended lighting device in which a plurality of light-emitting diodes are arranged in a matrix on a substantially planar substrate to form a light-emitting module (COB). module), and use the light emitting module as a light source (for example, refer to Japanese Patent Laid-Open No. 2004-95655). In addition, there is a lighting device in which a plurality of light-emitti...
