1. A light irradiation device comprising:
an injection unit configured to inject a sample; and
a light source configured to apply light to the sample to identify an abnormal cell in the sample, the light source including:
a substrate; and
a light emitter disposed on the substrate and comprising a light emitting diode,
wherein the light emitted from the light emitter is configured to cut a genetic material in the sample into sections of different sizes depending on a normal sample or an abnormal sample, and to deform the genetic material to different degrees, such that a determination of an abnormality of the sample is based on the degree of deformation of the genetic material, and
wherein an irradiation amount or an irradiation intensity of the light emitted from the light emitter is configured to be provided at an intensity in which a cytotoxicity value of the sample is greater than or equal to a predetermined value, and in which a ratio of a degree of deformation of the genetic material of the normal sample to a degree of deformation of the genetic material of the abnormal sample is set to be a minimum value outside an error range.
