A thermochromic decorative ornament

Abstract

The invention relates to a thermochromic ornament which comprises a shell, an LED light source module and a color changing unit. The bottom and the top of the shell are fixedly connected with a bottom base and an upper base respectively. The bottom base is provided with a base plate. The color changing unit comprises an inner lampshade, and the inner lampshade is in heat connection with the base plate and is of a transparent structure. A confined space is formed between the inner wall and the outer wall of the inner lampshade, and a partition plate for dividing the confined space into a containing cavity a and a containing cavity b in the left-right direction is arranged inside the confined space. When the temperature of the base plate is changed, the colors in the containing cavity a and the containing cavity b are changed. A color mixing area is formed between the outer wall of the inner lampshade and the shell. The shell is provided with a plurality of patterns. The patterns are made from semi-transparent materials with colors corresponding to color changes in the containing cavity a and the containing cavity b. By means of the characteristics of thermochromic materials and the liquidity of the thermochromic materials in the corresponding containing cavity a and the containing cavity b, the multiple patterns on the shell are changed through color changes of the color changing unit.

Description

technical field [0001] The invention relates to a decorative ornament, in particular to a thermochromic decorative ornament. Background technique [0002] As we all know, due to the color-changing characteristics of LED color-changing lights, it has better decorative properties, but compared with LED monochromatic lights, LED color-changing lights have high production costs, and each unit of LED color-changing lights consists of red, green, and blue. Composition of base color, supplemented by auxiliary circuits such as power supply part and color change control part, not only the manufacturing process is complicated, but also the use of complex circuits will increase the failure rate in actual use, and the maintenance cost is high. [0003] Chinese invention patent 201410584494.2 discloses a thermochromic LED lamp, which includes a lamp body, a substrate and a lighting unit. The substrate is arranged on the top surface of the lamp body. The lighting unit includes an LED ligh...

Problems solved by technology

[0004] According to the applicant's reflection, although the thermochromic LED lamp adopts LED light source and utilizes the characteristics of thermochromic materials, the color of the thermochromic device can change as the temperature changes, thereby realizing various lighting modes, but it still There are some problems. Due to the characteristics of light, the light of the same color can only pass through the material of the corresponding color. The lamp body of the above-mentioned thermochromic LED lamp can only be transparent, and the light that changes the color of the thermochromic device can pass through the lamp cap. body, the material of the lamp head body is single; in addition, the thermochromic device is made of thermochromic material, its color change is constant, and the light intensity is constant, so that the light change area value through the lamp body is small, and its decorative effect is poor.
