发明名称 Illuminated pole-suspended flag and method of illuminating
摘要 To enable legal twenty-four hour national flag display, to permit night display of vehicle-mounted school and team flags, and to do either with minimal increase in night sky light pollution, I mount a light source immediately adjacent a flag and direct the light essentially directly toward the flag, rather than upwardly into the sky. Preferably, the light source is provided within a transparent portion of the flag-mounting pole, and is ideally focused directly toward the flag by a reflector which is adapted to shift positions with changes in flag positions due to directional changes of air flow across the flag.
