Development of Light Projection Unit and Direction Switching Device for Solar Concentrating Canine Guidance Suit

Abstract

Research on canine guidance using spotlight stimulation is vital for the working canine mission. However, it is challenging to generate a spotlight with brighter illuminance using the presently available LED for easy detection of the spotlight by a canine. The limitation is due to the weight and size constraint for spotlight mounting on a canine, which is increased by an increase in heat generation and power consumption if brighten the illuminance. Therefore, by generating spotlight using sunlight, improving the illuminance while maintaining the weight and size constraint is possible. This paper proposes a device that can switch the sunlight induction direction in about 0.2 seconds for large-capacity sunlight and reduce the entire device's transmission loss for solar.
