Abstract
The invention relates to a portable illuminance detector with blue light detection. The portable illuminance detector with blue light detection includes an illuminance sensor which collects environmental illumination intensity and an environment detector which collects environmental blue light intensity, and a processor which obtains the environmental illumination intensity and environmental blue light intensity. The processor prestores a blue light health threshold value, generates a current blue light specific value according to the environmental blue light intensity and environmental illumination intensity and compares the current blue light specific value with a blue light threshold value, when the current blue light specific value is within the blue light threshold value, a safety signal is generated, and when the blue light specific value is beyond the blue light threshold value, the processor generates an alarm signal. The blue light intensity is monitored and whether the blue light intensity is within a safe value is judged, when the blue light intensity is not in the safe value range, an alarm is given, and thus the problem that blue light harms the eyes caused by lamp aging is avoided.
