9 Claims

1. An automatic analyzer for measuring a sample, comprising:

a light source for irradiating a reaction vessel storing the sample with light, and

a temperature adjustment mechanism for adjusting the temperature of the light source,

wherein the light source includes a first LED and a second LED,

wherein the light source is configured such that light emitted from the second LED is reflected on a reflective element to change an optical path, thereby the light emitted from the second LED is multiplexed with light emitted from the first LED on a same optical axis as that of light emitted from the first LED, and

wherein the temperature adjustment mechanism is configured by a member that is in contact with the first LED and the second LED respectively,

wherein a light intensity of the second LED is larger than a light intensity of the first LED,

wherein the light source further includes:

a first optical element that allows at least a part of first light emitted from the first LED to pass; and

a second optical element that reflects second light emitted from the second LED,

wherein the first optical element is configured to reflect at least a part of the second light,

wherein the first optical element and the second optical element are arranged such that the first light having passed through the first optical element and the second light reflected by the first optical element are configured to be multiplexed on a same optical axis to become multiplexed light,

wherein the first LED is a white LED that generates white light in a wavelength range of 350 nm to 800 nm, and

wherein the second LED is an ultraviolet LED that generates ultraviolet light having a central wavelength of 350 nm or less.
