摘要: A flashlight for security personnel has a gravity actuated switch application of electrical power to multiple lamps enable the projection light in downward directions illuminate multicolored working surfaces and inhibit horizontal other where hostile persons may be watching. The projected intensity is variable by polarizing optical means coordinated with user's control so that initial at turn-on occurs lowest intensity. lamp array, contained removable cartridge, emitters selected color characteristics, fast time decay response on turn-off, reduced red infrared energy emissions. Reversal battery polarity effects dramatic changes or light. manual overrides automatic unrestricted while tactile generator warns user high risk direction. Modular contruction cartridge permits selection optional lighting arrays accessories.
