Description

  The present invention relates to a guide light driving method and a guide light driving device for a guide light that can improve visibility.

For example, senile cataract is one of the visual impairments of the elderly. In the state where senile cataract has progressed, the crystalline lens of the eyeball becomes clouded, and a yellow or yellow-orange pigment remains inside, and the light arrival rate to the retina is deteriorated.
Visual impairment due to aging is an aging phenomenon in a sense and is an unavoidable phenomenon for elderly people, but even visually impaired people who have such visual impairments including cataracts even if they are not elderly people. Existing.
In order to ensure safety in driving automobiles and motorcycles by visually impaired persons, including those with visual impairment due to aging, and in evacuation guidance in buildings, guide lights and other lights that correspond to the visual characteristics unique to these visually impaired persons It is considered necessary to install an indicator.

As a guide light with improved visibility for such visually impaired persons, a guide light that is embedded in a road surface to guide traffic or call attention, a housing having a light transmitting portion on the upper surface, and a housing A first light emitting element that is provided on the lower side of the light transmissive portion in the body and that emits surface light from the light transmissive portion of the housing, and is provided on the lower side of the light transmissive portion in the housing and obliquely upward from the light transmissive portion of the housing There is a guide lamp composed of a second light emitting element that projects directional light and a control circuit that emits light from the first and second light emitting elements in response to ambient darkness (see Patent Document 1). ).

Based on the attribute of light that characterizes the visibility of each age group stored in the storage means, the light source of a plurality of primary color lights of the guide light is controlled, and a wide range of age groups including each age group And a light source control means for generating light with improved visibility against,
The attributes of the light that characterizes the visibility of each age group are the hue that characterizes the visibility of each age group that matches the visual characteristics unique to each age group, and the repetition period at which the light of that hue is emitted. Including
The light source control means performs control for adjusting the intensity of each primary color light emitted from the light source and the timing of light emission to the light sources of the plurality of primary colors, and has visual characteristics specific to each age group Light with a hue that matches the age and characterizes the visibility of each age group is generated at a different timing and the repetition cycle for each age group, and the light with improved visibility for a wide range of age groups including each age group Generating ,
