A full-color color-changing lamp with variable patterns

Abstract

The invention relates to a pattern-variable full-color color changing lamp. The pattern-variable full-color color changing lamp comprises a swinging lamp base and an outer shell; a substrate is arranged in the lamp base, and is provided with an LED light source set, a thermochromic unit a and a thermochromic unit b; the thermochromic unit a and the thermochromic unit b respectively include multiple thermochromic devices a and thermochromic devices b for respectively accommodating granular thermochromic materials a and thermochromic materials b; the LED light source set includes at least two sets of LED units layered from bottom to top; multiple patterns are arranged on the outer shell; the patterns are respectively manufactured by semitransparent materials with colors corresponding to the color change in the thermochromic devices; and the thermochromic devices show the patterns with corresponding colors on the surfaces thereof through light, irradiated by the LED light source set, penetrating through the outer shell by a color mixing area. The pattern-variable full-color color changing lamp realizes continuous change of colors and intensities of the light in the color mixing area, enhances the lamp appearance change effect, and changes the visual impression of users.

Description

technical field [0001] The invention relates to the technical field of colorful lamps, in particular to a full-color color-changing lamp with variable patterns. 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 time, the a...

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.
