The plant growth lamp with ultraviolet light of this creation substantially ties up on an ontology and is constructed with plural first photoelectric cell, and at least one second photoelectric cell； Wherein, each first photoelectric cell system generates predetermined band and photochromic plant light source for what energization Hou； Each second photoelectric cell system generates the ultraviolet light of predetermined band for what energization Hou. The growth light source of the illumination conditions such as frequency, amplitude, the period ratio for meeting application demand is provided by the first photoelectric cell, the ultraviolet light for meeting application demand is provided by the second photoelectric cell. The plant growth lamp with ultraviolet light of total demand of plant growth can be met in order to one kind is obtained本創作之具有紫外光的植物生長燈，基本上係在一本體上建構有複數第一光電元件，以及至少一第二光電元件；其中，各第一光電元件係供於通電後產生預定波段及光色的植物光源；各第二光電元件係供於通電後產生預定波段的紫外光。由第一光電元件提供符合應用對象需求之頻率、振幅、週期比率等光照條件的生長光源，由第二光電元件提供符合應用對象需求的紫外光。俾獲致一種可滿足全數植物生長需求之具有紫外光的植物生長燈
