A self-adjustable multi-color color-changing lamp

Abstract

The invention relates to an automatically adjusted multi-colored color-changing lamp. The automatically adjusted multi-colored color-changing lamp comprises a swingable lampholder and an outer housing, wherein a thermochromic unit is arranged in the outer housing. The thermochromic unit comprises an inner cover of the lamp and an LED light source set; a partition plate which divides the inner cover of the lamp into an accommodating cavity a and an accommodating cavity b which are independent to each other and in which a slurry-like thermochromic material a and a slurry-like thermochromic material b flow respectively, a color mixing region is formed between the inner cover of the lamp and the outer housing, and the LED light source set comprises at least two LED units which are layered from bottom to top; and a plurality of patterns which are made from a semitransparent material which has the color corresponding to color change in the inner cover of the lamp are arranged on the outer housing. According to the lamp provided by the invention, the LED light source set is arranged in a stair-step array, so that the different temperature regions are formed in the inner cover of the lamp from top to bottom; by combining the flowability of the thermochromic material, color and intensity of light penetrating through the thermochromic unit change continuously, so that diversity of appearance patterns of the lamp is achieved.

Description

technical field [0001] The invention relates to the technical field of multi-color lamps, in particular to an automatically adjustable multi-color and color-changing lamp. Background technique [0002] Recently, due to the advantages of long life, energy saving, high brightness, and small size, LED lights are more and more widely used, but usually need to use complex circuits to realize the color change of LED lights and produce different colors of light to meet people's needs. Diversity requirements for lighting quality. For example, each unit of an LED color-changing lamp is composed of three primary colors of red, green, and blue. In addition, it is supplemented by auxiliary circuits such as a power supply part and a color-changing control part. The above-mentioned circuits are not only complicated in manufacturing process, but also use complex circuits in actual use It will also increase the probability of problems, and the maintenance cost will be higher. At the same ...

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.
