Abstract

A light-emitting module (1) is provided with: a substrate (110); an LED chip (120) arranged on the principal surface side of the substrate (110); a sealing material (140) which is arranged on the principal surface side of the substrate (110) so as to cover the LED chip (120) and converts the wavelength of the light emitted from the LED chip (120); and a heat transfer member (160) which thermally couples the side surface of the LED chip (120) with the principal surface of the substrate (110) and dissipates the heat generated by the LED chip (120) to the substrate (110). The heat transfer member (160) is constituted by a silicone resin, and nano particles made from ZrO2 and micro particles (161) made from MgO which are dispersed in the silicone resin and have higher heat transfer rate than the silicone resin.

Description

technical field

[0001] The present invention relates to a light-emitting module using a semiconductor light-emitting element, and particularly relates to a technique for improving heat dissipation. Background technique

[0002] In recent years, semiconductor light-emitting elements such as LED (Light Emitting Diode) chips, incandescent bulbs or halogen bulbs have higher efficiency and longer life than incandescent bulbs, so they are expected to be new light sources for lamps. The LED chip is such that when its temperature rises, the light output decreases. Therefore, in a lamp using the LED chip, it is important to suppress the temperature rise of the LED chip.

[0003] Therefore, conventionally, lamps in which the temperature rise of the LED chip is suppressed have been proposed (see Patent Documents 1 and 2).

[0004] The lamps described in Patent Documents 1 and 2 include: a light-emitting module composed of a substrate and a plurality of LED chips mounted on the substr...
