Portable fluorescent drop-light

   
   

A hand-held fluorescent lamp assembly powered by typical line supply of 120 VAC, 60 Hz via an attached power cord and employing multiple commonly available fluorescent lamps. The assembly includes switches to independently control the multiple fluorescent lamps. The assembly includes lightweight solid state power regulation components. The power regulation circuit employs a self-oscillating circuit that is approximately matched in frequency of oscillation to the natural frequency of the fluorescent lamp load to automatically ignite the fluorescent lamps. The power regulation circuit includes circuit elements to automatically protect the ballast circuit and lamps from overdrawing in the run state and from abnormal load conditions.

Um conjunto hand-held da lâmpada fluorescente powered pela linha típica fonte de 120 VAC, de 60 hertz através de um cabo e de empregar de poder unido lâmpadas fluorescentes geralmente disponíveis do múltiplo. O conjunto inclui interruptores para controlar independentemente as lâmpadas fluorescentes múltiplas. O conjunto inclui componentes de pouco peso do regulamento do poder do estado contínuo. O circuito regulamentar do poder emprega um circuito self-oscilando que seja combinado aproximadamente na freqüência da oscilação à freqüência natural da carga da lâmpada fluorescente para inflamar automaticamente as lâmpadas fluorescentes. O circuito regulamentar do poder inclui elementos do circuito para proteger automaticamente o circuito e as lâmpadas do reator de overdrawing no estado do funcionamento e das condições de carga anormais.
