LIGHT-EMITTING APPARATUS

摘要

A circuit board (11) on which an LED element (14) is mounted is partitioned with a protection cover (30) (cover) arranged at the back face side of the circuit board (11) and with a transparent resin plate (80) (partitioning section) so that a narrow space (P) in which heat generated by the circuit board (11) is circulated by convection is formed, preventing thermal diffusion and facilitating the transfer of the heat circulated by convection to the protection cover (30) so as to raise the temperature of the protection cover (30). Thus, under conditions wherein snow or ice is deposited, snow or ice deposited on the protection cover (30) of a light-emitting apparatus is melted with the heat.
