Description
Technical Field
The invention belongs to the technical field of lighting lamps, and particularly relates to a lamp capable of changing color temperature and color based on an optical fiber light mixer.
Background
In the driving process of the vehicle, different color temperature matching modes are required for different weather, different road environments and different time points due to different external environments. For example, in rainy and foggy weather, the color temperature of the car lamp needs to be reduced so as to improve the light penetration effect of the car lamp and ensure the driving safety. In different driving environments, the LED lighting lamp needs to be matched with an external lighting object, so that the lighting effect is improved, and the driving safety is guaranteed. In cities, warm color and warm light are adopted to ensure the lighting and color development effects and ensure the driving safety; in the environment such as the expressway, cold color temperature illumination is adopted, so that the illumination brightness is improved, and the illumination distance is increased. Because the light source of the traditional LED vehicle lamp is usually a monochromatic light source, the traditional LED vehicle lamp only has a fixed color temperature and cannot realize the change of the color temperature. Meanwhile, the structural design of vehicle lamps with different color temperatures can not be realized by vehicle lamps such as xenon headlights, laser headlights and the like which are increasingly widely applied at present.
The existing color temperature variable car lamp solution usually adopts LED lamp holders composed of different color temperatures as light sources, and the biggest problem is that no corresponding light mixing structure design exists, so that the irradiation area of the car lamp has obvious illumination area distribution of different color temperatures, a part of the area is a high color temperature area, and a part of the area is a low color temperature area, thereby greatly influencing the illumination effect. Meanwhile, due to the fact that illumination areas with different color temperatures exist, judgment of a driver on the environment can be even seriously interfered, driving safety is greatly influenced, and great potential safety hazards exist.
Disclosure of Invention
The invention aims to provide a color temperature and color variable lamp based on an optical fiber light mixer, and aims to solve the problems of poor lighting effect and even potential safety hazard caused by no light mixing structure in the prior art.
In order to achieve the purpose, the technical scheme of the invention is as follows: a lamp with variable color temperature and color based on an optical fiber light mixer comprises an array type LED light source, the optical fiber light mixer, a reflector and a focalizer, wherein the array type LED light source comprises a plurality of LED lamps with different color temperatures, the LED lamps are divided into high color temperature LED lamps and low color temperature LED lamps, and the high color temperature LED lamps and the low color temperature LED lamps are alternately distributed in a matrix form; the optical fiber light mixer is positioned right above the array LED light sources and can intensively mix the light sources of the high-color-temperature LED lamps and the low-color-temperature LED lamps in the array LED light sources at the light outlet of the optical fiber light mixer; the reflector reflects the light mixed by the optical fiber light mixer, and the focalizer focuses the reflected light to enable the light to irradiate the area to be illuminated.
The working principle of the technical scheme is as follows: the light sources of the LED lamps with different color temperatures are concentrated at the light outlet of the optical fiber light mixer through the optical fiber light mixer. The light collected by the optical fiber light mixer is reflected by the reflector and transmitted to the focalizer. The focalizer has a focusing effect on the light, so that the light finally irradiates to an area to be illuminated.
The beneficial effects of this technical scheme lie in: by using the optical fiber light mixer, the LED lamps with different color temperatures can be uniformly mixed, so that the illumination area is ensured to form a bright area with uniform color temperature and adjustable color. And the high color temperature LED lamp and the low color temperature LED lamp are distributed alternately in a matrix form, so that the light source mixing effect of the LED lamps with different color temperatures is better, and the mixing is more uniform. Therefore, the problems that in the prior art, illumination areas with different color temperatures exist, judgment of a driver on the environment is seriously interfered, driving safety is greatly influenced, and great potential safety hazards exist are solved.
Furthermore, the optical fiber light mixer at least comprises two optical fibers, each optical fiber corresponds to one LED lamp, one ends of all the optical fibers are coupled, the whole structure of the optical fiber light mixer is of a claw-shaped structure, and the coupled optical fibers are used as light outlets of the optical fiber light mixer. The claw-shaped optical fiber light mixer can realize the collection of the light emitting wires positioned on different coordinate light sources.
Further, the reflector is a reflector cup.
Further, the focuser is a lens.
The LED lamp control system further comprises a control system for controlling the array type LED light sources to be turned on and turned off, and the control system can achieve independent turning on and turning off of each LED lamp.
