Title:
LIGHT-EMITTING MODULE
Document Type and Number:
Japanese Patent JP2023032709
Kind Code:
A
Abstract:
To provide a light-emitting module capable of achieving an energy saving by using a heat generation from a light-emitting device with a simple structure.SOLUTION: A light-emitting module (1) includes: a substrate (10) of a thermal conductivity; a first light-emitting device (41) mounted onto the substrate; first terminal pairs (21 and 22) for supplying an electric power supplied from an external power source while being arranged on the substrate to the first light-emitting device; a second light-emitting device (42) mounted onto the substrate; a thermoelectricity power module (50) connected to the substrate; and wirings (27 and 28) that are electrically insulated from the first terminal pair, are arranged on the substrate, and supply the electric power generated by the thermoelectricity power module by a heat generated by the first light-emitting device to the second light-emitting device.SELECTED DRAWING: Figure 2
