Embodiment Construction

[0063] The detailed description and technical content of the present invention are described as follows in conjunction with the drawings:

[0064] In order to enable your review committee members to better understand the technical content of the present invention, the preferred specific embodiments are described as follows.

[0065] Please refer to the following figure 1 It is a schematic diagram of the structure of the light source switching system of the present invention. It should be noted that although the following description uses the terms "first", "second" and so on to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first light emitting element could be termed a second light emitting element, and, similarly, a second light emitting element could be termed a first light emitting element without departing from the scope of the various described embodiments...

Abstract

The present invention provides a light source switching system and method. The system comprises a signal input terminal; first, second and third input circuits; a dimming control unit; a DC conversionunit; first and second switch circuits; and first, second and third light emitting elements. The second and third input circuits respectively include first and second detection units and first and second switch driving units. The DC conversion unit is connected to the first, second, and third input circuits and the dimming control unit. The first and second switch circuits are respectively connected to the DC conversion unit and the first and second switch driving units. The first light emitting device is connected to the DC conversion unit. The second and third light emitting devices are respectively connected to the first and second switch circuits, wherein the first, second and third light emitting devices are connected in parallel with each other.

Description

technical field [0001] The present invention relates to a light source switching system and a method for controlling the light emission of the light source, in particular to a light source switching system applicable to multiple light emitting diodes at the same time. Background technique [0002] The lighting system of today's cars includes lights with various functions, such as: daytime running lights, near lights, far lights, turn signals, fog lights, and position lights. Due to energy saving and styling requirements, all kinds of lamps have been gradually changed from halogen lamps to LED lamps. However, in the prior art, LED lamps with different functions use their own power supplies to drive the LEDs. This method will result in disadvantages such as large volume of LED power supplies, high cost, more electronic materials, and waste of resources. [0003] Therefore, it is necessary to invent a new light source switching system and a method for controlling the light emi...
