Description

TECHNICAL FIELD

[0001] The utility model relates to lighting equipment technical field especially relates to a lamp through multistage optical control realizes environmental light effect and the function coordination of wiping top. BACKGROUND

[0002] The prior art without main lamp adopts distributed point light source layout, although the oppression of single main light source can be avoided, but the following defects exist:

[0003] 1. Light effect is split: the obvious bright-dark boundary is caused by the dispersed light source, and the visual claustrophobia is easily formed;

[0004] 2. Single function: the traditional auxiliary light effect (such as lamp strip) can only realize local weak atmosphere illumination, and cannot form a large range of dynamic light and shadow;

[0005] 3. Poor interactivity: the light effect mode is fixed, and the light field form cannot be dynamically adjusted according to the scene requirement.

[0006] Part of the improvement scheme tries to integrate the projection structure in the lamp, but it uses fixed optical elements to realize static pattern projection, which has the following limitations:

[0007] ● Backlight module: outline light is formed through the lamp strip, but it is limited to static monochrome light effect;

[0008] ● Projection structure: pattern sheet is used to project patterns, which has the problems of difficult switching and being easily disturbed by the main light source.

[0009] ● Definition and energy consumption problem: the projection pattern has low definition, the area that can be illuminated is limited, and the phenomenon of projecting more and clearer patterns with fewer light sources cannot be realized, and increasing the power of the lamp can improve the definition but consume more energy.

[0010] The following core problems are not solved:

[0011] 1. Conflict of light path between basic illumination and atmosphere projection: when the high-brightness main light source and the low-brightness atmosphere light source share the diffusion cover, the light effects interfere with each other, resulting in blurred projection or decreased illumination uniformity;

[0012] 2. Discreteness of control system: the main light source and the atmosphere light source are independently controlled, lack of cooperative regulation mechanism, and cannot realize scene linkage (such as automatically switching mode according to environment light);

[0013] 3. Limited expandability: the optical elements (such as pattern sheet) are fixed as the lamp structure, and the user cannot replace or upgrade the projection effect as needed 4. Energy consumption problem: increasing the power of the lamp causes more energy consumption, and clearer patterns cannot be projected with fewer light sources. INVENTION CONTENT
