Decorative lamp with pattern changeable

Abstract

The invention relates to a decorative lamp with pattern changeable. The decorative lamp with pattern changeable includes a lamp holder capable of swinging and an outer shell, wherein the tail of the outer shell is in sealing connection with the lamp holder. A base plate is arranged within the lamp holder, and a LED light source group is arranged on the lamp holder. An annular thermochromism unit a and an annular thermochromism unit b are arranged on the inner wall of the outer shell from bottom to top, wherein the annular thermochromism unit a and the annular thermochromism unit b are intersected at equal interval. The annular thermochromism unit a is filled with granular thermochromic materials a, and the annular thermochromism unit b is filled with granular thermochromic materials b. The LED light source group includes at least two groups of LED units which are arranged in a layered mode from bottom to top; the outer shell is provided with a plurality of patterns; when the temperature of the base plate changes, after passing through the thermochromism unit a and the thermochromism unit b, the light emitted by the LED light source group passes through a color mixing region and then the outer shell, so that the surface of the outer shell shows a pattern with corresponding color. According to the decorative lamp with pattern changeable, the color mixing effect of the light is good, the color and intensity of the light in the color mixing region can change continuously, the appearance pattern of the lamp is changeable and the color change effect of the lamp are enhanced.

Description

technical field

[0001] The invention relates to the technical field of lamps, in particular to a decorative lamp with various 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 above-mentioned LED color-...
