Description

Technical Field

[0001] The invention relates to the technical field of lighting, and in particular to an LED strip light with adaptive light-changing capability. Background Art

[0002] On many off-road vehicles and vehicles that require outdoor lighting, additional lighting is required. These lighting devices are often installed on the front bumper of the vehicle. These lighting devices can project light in front of the vehicle to increase the driver's field of vision, but they can also cause glare to oncoming drivers. At the same time, it has become a trend to integrate signal position lights into lighting devices, so that signal lights will have obvious recognition.

[0003] Conventional additional lighting fixtures include both lighting lamps and signal position lamps integrated inside the lamps. In order to meet different lighting brightness requirements, the lighting light will have two light intensities: strong light (high light intensity) can illuminate a long distance, while weak light (low light intensity) can illuminate a short distance. In order to have two brightness levels of light intensity at the same time, two trigger lines are introduced in the current design. Through drive control, when the strong light connection is connected, the strong light is on; when the weak light connection is connected, the weak light is on. This solution has complicated circuit design and requires different drive controls; an additional connection needs to be introduced; it cannot be adaptively changed according to the scene, but requires manual control. The signal lamp integrated into the lighting fixture can only be used as a signal lamp that is always on when the lamp space is very small. Since there is no space to place the drive element to control the water flow effect, the water flow effect (each LED is lit one by one) cannot be achieved, and there is a lack of highlights in the lighting mode.
