LIGHT EMITTING DEVICE AND LIGHTING APPARATUS HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a light emitting device capable of suppressing breakage of a ceramic module substrate, while securing a heat radiation from the substrate to a module supporting member and ensuring predetermined electrical insulation.

SOLUTION: A wiring pattern 26 and a plurality of semiconductor light emitting elements electrically connected to the pattern are provided on a ceramic module substrate 22 to form a light emitting module 21 for a light emitting device. The light emitting module 21 received in a recess part 12 of a supporting member 11 is held so as to be pressed to a bottom surface 12a of the recess part by a holding member 70 fixed on the supporting member 11. The wiring pattern 26 being proximate to a peripheral surface 22c of a substrate is provided at a predetermined creeping distance E from the peripheral surface. Sizes of the module substrate and the recess part are determined so that a predetermined insulating distance F between a contact part and the wiring pattern 26 can be ensured in a state where the light emitting module is moved to the maximum so that the wiring pattern 26 closes to the contact part that the module substrate comes into contact with the holding member.
