Abstract
The utility model discloses an LED (light-emitting diode) lampshade which comprises a light uniformizing panel (1). The lampshade is characterized by also comprising a driving shaft (2) and light emitting elements (3), wherein the light emitting elements (3) can make a reciprocating translational motion under the support of the driving shaft (2); and the light emitting elements (2) are arranged at the back part of the light uniformizing panel (1) in parallel. The LED lampshade can be used as an auxiliary light source for lowering the flickering degree of the lamp; the reciprocating motion structure can conveniently control the motion speed variations of the light emitting elements, can better adapt to the working characteristics of LED lamp beads to carry out flickering stabilization, can further adjust the light direction and light color by using the light uniformizing panel, and has better light distribution performance.
Description
Technical field
The utility model relates to field of illuminating device, relates in particular to a kind of LED lampshade.
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; Caused widely and paid attention 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, yet no matter 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; 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 lampshade, uses on the LED lighting device, and the flicker to LED lamp pearl that can be meticulousr is stabilized, and can easily adjust by the photochromic of illumination apparatus.
The utility model adopts following technical scheme to realize: a kind of LED lampshade, comprise even tabula rasa, driving shaft and illuminating part, and illuminating part can reciprocal translational motion under the support of driving shaft, and illuminating part is set in parallel in even tabula rasa rear portion.
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.
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 illuminating part of said illuminating part also includes embedded photoluminescent material layer and/or filter layer.
The further technical scheme of the utility model is: said even tabula rasa is provided with embedded photoluminescent material layer and/or filter layer.
Adopt the LED lampshade of this structure; Can be used as the secondary light source of lighting device, be used to reduce the flicker level of light fixture, adopt shuttle motion structure; Can easily control the variation of the movement velocity of illuminating part; The operating characteristic that can better adapt to LED lamp pearl is glimmered and is stabilized, and can further adjust direction of light and photochromic through even tabula rasa, and luminous intensity distribution property is better.
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection domain of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.
Description of drawings
Fig. 1 is the perspective view of a specific embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
As shown in Figure 1; This LED lampshade is assembled by even tabula rasa 1, driving shaft 2, illuminating part 3, and illuminating part 3 is set in parallel in even tabula rasa 1 rear portion, can reciprocal translational motion under the drive of driving shaft 2; Illuminating part 3 is the single-layer plate-like structure; Be intervally distributed with illuminating part and penetrating portion on it, form through superimposition long after glow luminous material layer on substrate, used long-afterglow material and selecting for use of LED lamp pearl adapt; Can receiving at least, the bright dipping of partial L ED lamp pearl excites; The logical hole 4 that the some evenly spaced parallel arrays in hollow out place are arranged on the substrate, said logical hole 4 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; In order to improve the colour rendering of lighting device, be provided with the embedded photoluminescent material layer of multiple color on the even tabula rasa 1 of present embodiment according to evenly spaced spot form.
