Please refer to Fig. 3, it is the schematic perspective view of the multidimensional lighting device 30 according to one embodiment of the invention.
The multidimensional lighting device 30 of the present embodiment is electrically connected to a standardization electric power system 3 equally.Multidimensional lighting device 30 comprises many wire 30a, two electrode 30b, carrier 32,1 first photoelectric cell 34 and four the second photoelectric cells 36.Separately do not repeat at this with the same or analogous element of previous embodiment.
In detail, first photoelectric cell 34 of the present embodiment adopts blue light-emitting diode array 34a to excite the first wave length conversion body 34b of tool red fluorescence powder, second photoelectric cell 36 adopts the green light LED array by many green light LED tube cores, implements also only to use single green light LED tube core in aspect at other.
Standardization electric power system 3 is electrically connected with multidimensional lighting device 30, for providing standardization voltage and/or electric current.First photoelectric cell 34 and the second photoelectric cell 36 produce one first light and one second light respectively, and the first light and the second light are mixed into a mixed light and project.Blue light, ruddiness and green glow can be comprised in this mixed light.The ratio of this three look of suitable adjustment can be arranged in pairs or groups out various coloured light, such as, can obtain bulb coloured light (warm white), cold white light or other coloured light that mixing three primary colors can be utilized to obtain.In addition, if great majority or whole blue lights are consumed in generation ruddiness, then in mixed light, the ratio of blue light close to 0 or will be less than 5% or be less than 1.
