Abstract

The invention relates to a thermally-induced cyclic color variation LED lamp which comprises an LED light source module, a lampholder, a lamp outer cover, a lamp inner cover, a base plate and a temperature adjusting device. Part of the lamp inner cover is coated with a thermally-induced color variation material a, and the other part of the lamp inner cover is coated with a thermally-induced color variation material b; a pattern a, a pattern b and a pattern c are arranged on the lamp outer cover; the other part, except the pattern a, the pattern b and the pattern c, of the lamp outer cover is made from an opaque material; and the temperature adjusting device is arranged on the portion, on the outer side of the lamp inner cover, of the base plate. By adoption of the color variation LED lamp, the problems that different color lamp bodies need to be combined and matched with auxiliary circuits of all parts, the number of structures is large, the manufacturing process is complicated, and the cost is high are solved.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a thermally induced cyclic discoloration LED lamp. Background technique [0002] Usually, complex circuits are required to realize the color change of LED lights. For example, each unit of LED color-changing lights is composed of three primary colors of red, green, and blue. Not only the manufacturing process is complicated, but also the use of complex circuits will increase the probability of problems in actual use, and the maintenance cost is also high. At the same time, the above-mentioned LED color-changing lamp also greatly increases the production cost of the product compared with the LED monochromatic lamp, and brings a great economic burden to users.
