Background technology

LED (light emitting diode) compares than incandescent lamp, electricity-saving lamp, has advantages such as energy-conservation, durable, pollution-free, is regarded as lighting system of future generation the most likely, has caused widely to pay attention to.The basic principle of luminosity of light emitting diode is: in the semiconductor in the carrier recombination process; The excess energy of emitting causes photo emissions, and versicolor light waves such as outgoing is red, indigo plant belong to the cold light source that electric energy directly arrives luminous energy; On principle of luminosity, has outstanding advance; LED these exclusive principle and characteristics, the superiority of not only having brought LED to use as light source has proposed a series of brand-new requirements also for simultaneously the LED illumination application; Such as LED photochromic single, rising angle is little, caloric value is big, unidirectional conducting or the like, all need in concrete illumination scheme, adapt to.Because light emitting diode has unidirectional conduction, in order to remain on the stabilized illumination in the illumination application, present way is to adopt direct current to drive; No matter yet be family, industry and commerce or public electricity-using at present, the mode with alternating current provides mostly, must in light fixture, attach rectifier transformer for this reason and carry out the ac/dc conversion; This mode can be brought extra power consumption, and can reduce the product bulk life time, answer this; Chinese patent document CN101208813B discloses a kind of " light-emitting device that is used for AC power operation ", and this device comprises LED wafer, and this LED wafer has the luminescence unit that is connected in series of array; And the switching blocks that is connected respectively to the node between these luminescence units, wherein when this array is connected to ac voltage power supply and is driven by this ac voltage power supply, open and close these luminescence units successively by these switching blocks; This light-emitting device can in turn be opened these arrays under AC power; Then according to these arrays of opposite orderly close-down, thereby scintillation effect can be lowered, and fluorescent lifetime can be increased; But this scenario-frame is complicated, high to the requirement of manufacturing process.

The utility model content

The purpose of the utility model is to provide a kind of LED illuminating lamp of novel structure, under the driving of ac voltage power supply, and the amount of light approximately constant of this illuminating lamp, scintillation effect is low.

The utility model adopts following technical scheme to realize: a kind of LED illuminating lamp; Include lamp body, LED lamp pearl, AC driven power; LED lamp pearl divides into groups and is connected with AC driven power through circuit; Each is organized LED lamp pearl and under the driving of AC driven power, divides into groups chronologically to open and close; This LED illuminating lamp 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 be positioned at LED lamp pearl front end, cover partial L ED 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 utility model is: said illuminating part is the single-layer plate-like structure, is intervally distributed with illuminating part and penetrating portion on it, and illuminating part is connected on the driving shaft, can reciprocal translational motion under the drive of driving shaft.

The further technical scheme of the utility model is: said illuminating part adopts layer structure; Constitute through on substrate, being formed with the long after glow luminous material layer; On illuminating part, engrave out some logical holes at interval; Said logical hole promptly constitutes the penetrating portion of illuminating part, and the position that is formed with the long after glow luminous material layer on the substrate promptly constitutes the illuminating part of illuminating part.

The further technical scheme of the utility model is: the evenly spaced parallel array in said logical hole is arranged; Said 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, and 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 utility model is: during illuminating lamp work, the illuminating part of illuminating part covers the LED lamp pearl group of firmly closing all the time.

Adopt the LED illuminating lamp of this structure, form the relative motion structure through 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; The LED lamp pearl intermittently starting that adopts common unidirectional conducting with close, can reduce the generation and the alluvial of caloric value, and the mode through 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 adopts the structure of the reciprocal translational motion of illuminating part; The shape and the position in logical hole can be set more flexibly, make things convenient for the heat radiation and the luminous intensity distribution design of light fixture.
