The utility model content

The purpose of the utility model is to provide a kind of high-color rendering LED illuminating lamp of novel structure, and its bright dipping includes abundanter color, have better colour rendering, and bright dipping is even, and can adapts to the alternate current operation condition.

The utility model adopts following technical scheme to realize: high-color rendering LED illuminating lamp; Include lamp body, LED lamp pearl, power supply; LED lamp pearl is connected with power supply through circuit; This LED illuminating lamp also includes drive system and photochromic regulating part, and photochromic regulating part can be done the motion of pivoting under the support of drive system, and the grouping distributed architecture of LED lamp pearl and the structure of photochromic regulating part adapt; Photochromic regulating part is positioned at the front end of LED lamp pearl, and unlatching and the closing timing of rotatablely move sequential and each group LED lamp pearl of photochromic regulating part adapt.

The further technical scheme of the utility model is: said photochromic regulating part adopts layer structure; Superimposition has embedded photoluminescent material layer and/or filter layer in blade basic unit, and said embedded photoluminescent material layer and/or filter layer are complementary with the luminescent spectrum of partial L ED lamp pearl at least.

The further technical scheme of the utility model is: said power supply is an AC driven power, and LED lamp pearl divides into groups and is connected with AC driven power through circuit, and each is organized LED lamp pearl and under the driving of AC driven power, divides into groups chronologically to open and close.

The further technical scheme of the utility model is: said photochromic regulating part adopts blade shape, and the blade of some separations evenly links into an integrated entity at interval and through rotating shaft, and under the drive of drive system, photochromic regulating part rotates around the shaft.

The further technical scheme of the utility model is: LED lamp pearl is according to distributing with the coaxial disc type of photochromic regulating part; And it is evenly spaced by the sector grouping; Sector in the middle of every group is opened simultaneously or is closed, and the envelope shape of arbitrary group of LED lamp pearl is identical with the shape of photochromic regulating part.

The further technical scheme of the utility model is: during illuminating lamp work, photochromic regulating part skims over the LED lamp pearl group of work, when LED lamp pearl group is opened and reached high-high brightness, it is revealed fully.

Adopt the high-color rendering LED illuminating lamp of this structure, the embedded photoluminescent material layer that is provided with on the photochromic regulating part can be excited by the bright dipping of monochromatic LED light source, sends the light of required color; Filter layer then can filter the bright dipping of led light source; Change photochromicly, select as required to design after the photochromic regulating part, photochromic adjustment part rotates under the drive of drive system; Thereby make the bright dipping of light fixture reach balance; Simultaneously, this programme adopts LED lamp pearl to cooperate photochromic regulating part and through the LED lamp pearl that photochromic regulating part cover is closed, can adapt to the alternate current operation condition.
