[0003] The current surface lighting method relies on direct light from LED lamps. In order to achieve the optimal effect of uniform light output, an appropriate distance needs to be maintained between the LED lamp and the mask. This appropriate distance will lead to an increase in the layout space, otherwise the mixed light effect will be unsatisfactory and the dispersion will be serious. Utility Model Content
[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:
[0005] Interior surface light source atmosphere lamp with mixed light structure, including:
[0006] panel;
[0007] a light concentrator; and
[0008] Light strips;
[0009] The light concentrator is located between the panel and the light strip, the light strip is evenly arranged, the light-emitting sides of the light strip correspond to the light concentrator, and the light emitted by the light strip is mixed by the light concentrator and then passes through the panel.

[0017] Beneficial effects of the utility model:
[0018] 1. The light emitted by the light strip first passes through the condenser, and the light is first reflected multiple times in the condenser to increase the mixed light path. Then the light can be mixed more fully, and the light emitted from the panel will not have dispersion and color spots.
[0019] Since the position and space for arranging the panel are determined, the corresponding focusing piece can be designed according to the size data. Since the panel and the light strip are located on both sides of the focusing piece, the distance between the panel and the light strip is mainly determined by the controllable thickness of the focusing piece. Therefore, the arrangement space of the atmosphere light is relatively controllable and has better adaptability.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0025] See also Figure 1 As shown, Figure 1 This is a structural diagram of an existing atmosphere lamp that uses a light guide plate to convert LED light into surface light.
[0026] In the existing structure, the surface luminescence method relies on LED lamps to emit light directly, and the light angle is completely dependent on the light divergence angle of the light strip 3 itself. However, the light angle of the light strip 3 itself is large and is blocked by the panel 1. The utilization rate of the large-angle light is relatively low, or even directly wasted.
[0027] At the same time, in order to achieve the optimal effect of uniform light output, an appropriate distance needs to be maintained between the LED lamp and the mask. This appropriate distance will lead to an increase in the layout space, otherwise the mixed light effect will be unsatisfactory and the dispersion will be serious.
[0028] See also Figure 2 As shown, in order to solve the above technical problems, a technical solution of an interior surface light source atmosphere lamp with a mixed light structure is provided:
[0029] An interior surface light source atmosphere lamp with a mixed light structure comprises: a panel 1, a focusing element 2 and a light strip 3.
[0030] The concentrator 2 is located between the panel 1 and the light strip 3 , the light strip 3 is evenly arranged, the light-emitting sides of the light strip 3 correspond to the concentrator 2 , and the light emitted by the light strip 3 is mixed by the concentrator 2 and then passes through the panel 1 .
[0031] Specifically, in order to make full use of large-angle light and improve the light mixing effect, a focusing piece 2 is added between the panel 1 and the light strip 3. The setting of the focusing piece 2 can better collect large-angle light to the required area on the one hand, and increase the utilization rate of light and the brightness of light on the other hand.
[0032] The light emitted by the light strip 3 first passes through the focusing element 2, and the light is first reflected multiple times in the focusing element 2 to increase the light mixing path, so that the light can be mixed more fully, and the light emitted from the panel 1 will not have dispersion and color spots.
[0033] Since the position and space of the panel 1 are unknown, the corresponding focusing piece 2 can be designed according to the size data. Since the panel 1 and the light strip 3 are respectively located on both sides of the focusing piece 2, the distance between the panel 1 and the light strip 3 is mainly determined by the controllable thickness of the focusing piece 2. Therefore, the layout space of the atmosphere light is relatively controllable and has better adaptability.
[0034] To facilitate understanding of the technical solution of the present application, further description is given to the light concentrator 2. The light concentrator 2 mainly achieves the effect of sufficient light mixing by increasing the light mixing path.
[0035] In one embodiment, the focusing element 2 includes: a single mixing zone 21 and a multi-mixing zone 22 .
[0036] The single mixing zone 21 is used to collect large-angle light and increase the mixing light path, and the single mixing zone 21 corresponds to the light strip 3 one by one, that is, each light strip 3 corresponds to a single mixing zone 21, thereby ensuring that the light emitted by each light strip 3 is collected and the mixing light path is increased.
[0037] The multi-mixing zone 22 is used for final light mixing, and the single mixing zone 21 is connected to the multi-mixing zone 22. That is, the light emitted by all the light strips 3 passes through the single mixing zone 21 to increase the mixing path, is fully mixed in the multi-mixing zone 22, and then is emitted from the panel 1.
[0038] In one embodiment, the single mixing zones 21 are spaced apart to avoid light mixing when collecting large-angle light and increasing the light mixing path, thereby improving the controllability and uniformity of light mixing. The outer walls of adjacent single mixing zones 21 and the outer walls of adjacent multi-mixing zones 22 are mirror reflection walls a, which can prevent light from being refracted and waste light. The mirror reflection walls are mirror polished, and a reflective coating or reflective stickers are used when necessary.
[0039] In one embodiment, a light entrance groove 4 for light to enter is opened on the side surface of the light strip 3 corresponding to the single mixing zone 21 , and the light entrance groove 4 is located in the middle of the side surface corresponding to the single mixing zone 21 .
[0040] The inner wall of the light entrance groove 4 is not a mirror radiating wall to ensure that the light can fully enter the single mixing zone 21. The light entrance groove 4 is set at the middle position of the corresponding side of the single mixing zone 21 to ensure that the large-angle light enters the single mixing zone 21 symmetrically and ensures uniform light mixing.
[0041] The top surface of the multi-mixing zone 22 is a plane or an arc-shaped surface, and is actually designed according to the shape of the panel 1 and is not limited to a specific shape.
[0042] The cross section of the single mixing zone 21 is a trapezoid, and the upper bottom is near the light strip 3. The cross section of the single mixing zone 21 is set to be a trapezoid, so that after the light enters the single mixing zone 21, the reflected light can pass through the multi-mixing zone 22 and then be emitted.
[0043] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
