Method for enabling automobile interior lamp to form mixed color streamer effect and automobile interior lamp

Abstract

The invention discloses a method for enabling an automobile interior lamp to form a mixed color streamer effect and the automobile inteior lamp, wherein a first light source and a second light sourceare arranged at the left end and the right end of a light guide element of the automobile interior lamp respectively, and each of the first light source and the second light source comprises a light-emitting element capable of emitting red primary color light, green primary color light and blue primary color light. The first light source and the second light source are electrically connected withthe controller, the controller is used for controlling the light-emitting elements of the three primary colors to emit light simultaneously or randomly according to a specific time sequence, and lightemitted by the first light source and the second light source is projected into the light guide elements from the two ends of the light guide elements to be conducted. Therefore, the light guide element generates a mixed color and a visual effect of light flowing. As long as a small number of LED light sources are used, the light rays can be mixed in the light guide element to change the light emitting color by controlling the LEDs to emit light simultaneously or randomly according to a specific time sequence, so that the light guide element has the visual effects of mixing the light rays andenabling the light rays to flow.

Description

technical field [0001] The present invention relates to a method for controlling lighting and decorative lamps installed in automobiles and the automobile interior lamps formed by using the method, especially a method for making the automobile interior lamps form a mixed-color streamer effect and the automobile interior lamps . Background technique [0002] Based on the reasons of long service life and power saving, it has become a general trend to use light emitting diodes (LEDs) as light sources for lighting, warning or decoration purposes. Taking the decorative lamps in automobiles as an example, LEDs are mostly used as light sources at present. However, due to the limited light intensity that a single LED can emit, it usually takes several LEDs to form a group of lamps, and because a group of lamps The higher number of LEDs used makes the cost higher, and the light emitted directly by the LEDs is also less soft. [0003] Taiwan Patent No. M310297 provides a luminous ro...
