Technical Field

The invention relates to the technical field of electronics, in particular to a color-changeable lampshade made of an electrochromic sheet.

Background

At present, the interior decoration styles are various, and the interior decoration of industrial wind is very popular. 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

Aiming at the defects in the prior art, the invention provides the lampshade with variable colors. 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 purpose of the invention is realized by the following technical scheme:

the present invention is composed of an electrochromic sheet 1, a driving electrode included in the electrochromic sheet, and a power control device 3 to which the driving 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 of the invention, the lampshade can be cut according to the size of the light emergent surface of the lamp, so that the requirements of various lamps in interior decoration are met.

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

As a further improvement of the invention, the lamp housing comprises a power control device mounted in connection with the power supply line, said power control device being adapted to individually power said electrochromic cells.

As a further improvement of the invention, the power supply and the control circuit contained in the power supply control device are connected through a power line and a control line, and the switch of the lampshade can be controlled independently through the control device.

As a further improvement of the invention, the power supply control device adjusts the output voltage pulse width through the control circuit to change the light transmittance of the lampshade, thereby meeting the requirement on the brightness degree.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the advantages that: the invention installs the common electrochromic film on the outer layer of the lamp, which has the effect of black when not being lighted, under the state of not turning on the lamp, the whole lamp is completely integrated in the dark background, the light transmittance is less lost under the state of turning on the lamp, the normal lighting requirement can be met, and the shape, the size and the pattern of the electrochromic film can be customized according to the requirement of a customer, so that the electrochromic film can be applied to lamps of various styles to meet the requirements of different lighting effects. The invention has independent power supply, can directly replace the diffusion cover of the prior lamp, and can meet the decoration requirement without purchasing the lamp again.
