Description

lamps

technical field

Embodiments of the present disclosure generally relate to a light fixture.

Background technique

At present, the application of colored lamps in residential and commercial lighting is more and more common, which can be used to create different atmospheres. Common colored lamps include the following types, such as colored bulbs, colored ceilings, colored panels, and colored wall washers. For colored light bulbs, although a single light bulb can change color in some cases, it can only produce one color at the same time, and cannot provide illumination of multiple colors at the same time, let alone provide a luminous effect with color gradients. For colored ceilings and colored panels, they usually can only provide lighting of different colors on different parts or different areas, but cannot produce a luminous effect of color gradients on a single part or a single area. As for the wall washer, it can only produce colorful luminous effect on the wall through projection, but the wall washer itself cannot provide the luminous effect of color gradient.

It can be seen that conventional colored lamps do not have the ability to mix colors on the light-emitting surface of the lamp, and cannot produce a luminous effect of color gradients on the light-emitting surface of the lamp.
