Analysis device

Abstract

Provided is an analysis device including a light-emitting diode (LED) light source capable of suppressing changes in an emission spectrum and a light amount and preventing condensation. The analysis device includes an LED light source (an excitation light LED 501, a phosphor 502, and an LED package 503) that generates light with which a sample is irradiated, an LED mounting board 504 on which the LED light source and a temperature sensor 505 are mounted, a lamp house 508 that surrounds a periphery of the LED mounting board 504 and contains the LED mounting board 504, a Peltier element 506 that absorbs heat of the LED mounting board 504 or dissipates heat to the LED mounting board 504, and a control unit that controls an output from the Peltier element 506 so that a temperature measured by the temperature sensor 505 becomes higher than a threshold temperature.

Dependencies are inferred from the claim text.
