Byla j\u00edm z\u00e1\u0159ivka LightPark. Ta fungovala na pon\u011bkud jin\u00e9m principu. Zat\u00edmco \u017e\u00e1rovka funguje tak, \u017ee se roz\u017ehav\u00ed na vysokou teplotu dr\u00e1tek um\u00edst\u011bn\u00fd ve sklen\u011bn\u00e9 ba\u0148ce, ve kter\u00e9 je vakuum aby se p\u0159ede\u0161lo vzniku ohn\u011b, z\u00e1\u0159ivky funguj\u00ed trochu jinak.\tJedn\u00e1 se o sklen\u011bnou trubici, napln\u011bnou plynem \u010di sm\u011bs\u00ed plyn\u016f, kter\u00e9 p\u0159i vy\u0161\u0161\u00ed teplot\u011b vyd\u00e1vaj\u00ed sv\u011btlo. Na onu po\u017eadovanou teplotu jsou potom dost\u00e1v\u00e1ny pomoc\u00ed elektrick\u00fdch v\u00fdboj\u016f. Nev\u00fdhodou je, \u017ee v z\u00e1vislosti na objemu plynu a tedy velikosti sklen\u011bn\u00e9 n\u00e1doby mohlo chv\u00edli trvat, ne\u017e se dos\u00e1hlo po\u017eadovan\u00e9 teploty a tedy i pln\u00e9ho jasu. Obvykl\u00e1 doba byla kolem deseti minut.\tV\u00fdhodou v\u0161ak byla \u00faspornost. Jakmile se toti\u017e dos\u00e1hlo dan\u00e9 teploty, na jej\u00ed udr\u017eov\u00e1n\u00ed bylo nutn\u00e9 u\u017e jen minimum energie, a to d\u00edky reakc\u00edm, kter\u00e9 v plynu prob\u00edhaj\u00ed a kter\u00e9 samy o sob\u011b generuj\u00ed teplo. Zd\u00e1lo by se tedy, \u017ee je to dobr\u00fd zp\u016fsob, jak u\u0161et\u0159it pen\u00edze.\tP\u0159esto se v dom\u00e1cnostech p\u0159\u00edli\u0161 neuchytila, a to p\u0159edev\u0161\u00edm pr\u00e1v\u011b kv\u016fli dlouh\u00e9 dob\u011b, kter\u00e1 byla pot\u0159eba k pln\u00e9mu na\u017ehaven\u00ed. Uplatn\u011bn\u00ed v\u0161ak na\u0161la tam, kde je nutno sv\u00edtit prakticky neust\u00e1le, jako jsou obchody, chodby nemocnic a podobn\u011b.\tAv\u0161ak v\u00fdvoj se nezastavil, a to plat\u00ed i pro z\u00e1\u0159ivky. Byla objevena sm\u011bs plyn\u016f, kter\u00e1 vyd\u00e1v\u00e1 je\u0161t\u011b v\u00edce sv\u011btla.
