Summary of the invention
The object of the present invention is to provide a kind of reciprocating type LED lighting device of novel structure, under the driving of ac voltage power supply, the amount of light approximately constant of this lighting device, scintillation effect is low.
The present invention is realized by the following technical solutions: reciprocating type LED lighting device, include lamp body, LED lamp pearl, AC driven power, LED lamp pearl divides into groups and is connected with AC driven power by circuit, each is organized the chronologically grouping under the driving of AC driven power of LED lamp pearl and opens and close, this LED lighting device also includes drive system and illuminating part, under the support of drive system illuminating part relatively LED lamp pearl do reciprocal translational motion, the grouping distributed architecture of LED lamp pearl and the structure of illuminating part adapt, illuminating part is positioned at the front end of LED lamp pearl, cover part LED lamp pearl, unlatching and the closing timing of the reciprocal translational motion sequential of illuminating part and each group LED lamp pearl adapt.
The further technical scheme of the present invention is: described illuminating part is the single-layer plate-like structure, is intervally distributed with illuminating part and penetrating section on it, and illuminating part is connected on the driving shaft, can back and forth translational motion under the drive of driving shaft.
The further technical scheme of the present invention is: described illuminating part adopts layer structure, consist of by be formed with the long after glow luminous material layer at substrate, some logical holes are engraved out at the interval on illuminating part, described logical hole namely consists of the penetrating section of illuminating part, and the position that is formed with the long after glow luminous material layer on the substrate namely consists of the illuminating part of illuminating part.
The further technical scheme of the present invention is: the evenly spaced parallel array in described logical hole is arranged, described LED lamp pearl is arranged according to the evenly spaced rectangular array of the position corresponding with illuminating part, LED lamp pearl is evenly spaced to be divided into two groups, the LED lamp pearl in the logical hole of corresponding illuminating part is same group simultaneously, LED lamp pearl is on the same group opened simultaneously or closes, and two LED lamp pearls are organized unlatching one by one or close.
The further technical scheme of the present invention is: during lighting device work, the illuminating part of illuminating part covers the LED lamp pearl group of firmly closing all the time.
Adopt the LED lighting device of this structure, form the relative motion structure by the translation of illuminating part between the two on main light source LED lamp pearl and secondary light source illuminating part, under the driving of ac voltage power supply, adopt common one-way conduction LED lamp pearl intermittently starting and close, can reduce generation and the alluvial of caloric value, and the mode by relative motion, but the LED lamp pearl that the illuminating part cover is closed, keep the amount of light approximately constant, scintillation effect is low, and the structure of the reciprocal translational motion of employing illuminating part can arrange the shape and the position that lead to the hole more flexibly, makes things convenient for heat radiation and the luminous intensity distribution design of light fixture.
