The lamp product needs to meet the decoration style with dark background, and usually adopts a mode of adding dark materials in a diffusion cover and spraying the dark materials in the lamp, and the mode greatly sacrifices light transmittance which is usually only 20-30% or even lower.

Disclosure of Invention

The utility model provides a but the lamp shade of colour change to the defect that exists among the prior art. The problems to be solved are as follows: a lampshade is made of common electrochromic pieces and is arranged on the outermost layer of a common lamp. The LED lamp can be fused in a dark background under the state of not turning on the lamp, the light transmittance is less lost under the state of turning on the lamp, and the normal illumination requirement can be met.

The utility model aims at realizing through the following technical scheme: the utility model discloses constitute by the drive electrode that electrochromic piece 1, electrochromic piece contained and the power control device 3 that the drive electrode is connected. The electrochromic sheet 1 is arranged on the outermost layer of the light-emitting surface of the lamp and on the diffusion plate 4 of the lamp. The driving electrodes included in the electrochromic film 1 are connected to a power control device 3 through a power line 2. The power control device 3 comprises a power supply, a power line, a control circuit and a control device (the control device in the embodiment has two control modes of wireless control and wired control). Under the condition of no electricity, the electrochromic film is in a dark color and is fused with a dark color background. Under the condition of electrifying, the electrochromic sheet is transparent and light-transmitting, and meets the normal illumination requirement.

As a further improvement, the lampshade can be cut according to the size of the light emitting surface of the lamp, and the requirements of various lamps in the interior decoration are met.

As a further improvement of the utility model, the lampshade can achieve the effect of displaying various patterns and characters by customizing the electrochromic sheet or printing the characters and patterns on the diffusion plate.

As a further improvement of the utility model, the lamp shade is including installing the power control device who is connected with the power cord, power control device is used for giving alone the electrochromic piece supplies power.

As a further improvement of the utility model, the power supply that power control device contained passes through the power cord with control circuit and is connected, can the switch of independent control lamp shade through controlling means.

As a further improvement, the power control device adjusts the voltage pulse width of output through the control circuit to change the light transmittance of the lampshade, and meets the requirement on the light and shade degree.

Since the technical scheme is used, compared with the prior art, the utility model, the advantage and the effect that have are: the utility model discloses install ordinary electrochromic piece in the outer layer of lamps and lanterns, it is black effect to play not to light, under the state of not turning on the light, make a whole set of lamps and lanterns fuse completely in the middle of the dark background, lose the luminousness again less under the state of turning on the light, can satisfy normal illumination needs, but also can be according to the shape, size and the pattern of customer's demand customization electrochromic piece, make it can use in the middle of the lamps and lanterns of various styles, satisfy different illuminating effect's needs. Because of the utility model discloses possess independent power supply by oneself, can directly replace the diffusion cover of current lamps and lanterns, need not purchase lamps and lanterns again, just can satisfy the decoration needs.
