The Z direction in fig. 3 is the height direction and also the up-down direction.

Referring to fig. 1 to 6, the present embodiment provides a light emitting structure, which includes:

A light source 500;

The light collecting member 200, the light collecting member 200 includes a light reflecting portion 210 and a light transmitting portion 220;

The light guide 300, the light guide 300 is used for providing the light to radiate;

the main body 100, the main body 100 is provided with a containing cavity (not marked in the figure), the light source 500 and the light collecting piece 200 are both positioned in the containing cavity, the light source 500 is positioned at the bottom of the light collecting piece 200, and the light guiding piece 300 penetrates through the main body 100;

A part of the light emitted from the light source 500 is reflected by the light reflecting portion 210 to form a first light path 10, and the other part passes through the light transmitting portion 220 to the light guiding member 300 and passes through the light guiding member 300 to form a second light path 20.

In the present embodiment, please refer to fig. 3 and 6, the light reflecting portion 210 can refract a portion of the light emitted by the light source 500, so when the portion of the light source 500 strikes the light reflecting portion 210, the light emitting portion can concentrate the portion and emit the portion out of the main body 100 from bottom to top, and at this time, the light path is the first light path 10. The light-transmitting portion 220 can transmit light, so that another portion of the light may directly pass through the light-transmitting portion 220 after the light-transmitting portion 220 is irradiated, or may pass through the light-transmitting portion 220 after being reflected from the reflecting surface 110, and the portion of the light may be irradiated to the light-guiding member 300. At this time, since the light guide 300 is inserted into the main body 100, one surface of the light guide 300 is located in the accommodating cavity, and the other surface is located outside the main body 100, so that the light is emitted from the light guide 300 after being irradiated to the light guide 300, thereby forming the second optical path 20. Therefore, when the light emitting structure of the present embodiment emits light, it has at least two light effects, wherein one light effect is the first light path 10 and the other light effect is the second light path 20.

In summary, the present embodiment realizes at least dual light effect lighting through the single light source 500, effectively improves atmosphere, reduces aesthetic fatigue possibility of users, and reduces production cost of the lighting structure.

It can be understood that referring to fig. 3 and 6, the light guide 300 may be directly disposed within a linear path range of the light passing through the light transmitting portion 220, or may be disposed outside the linear path range, and when the light guide 300 is disposed outside the linear path range of the light passing through the light transmitting portion 220, the light can be reflected to the light guide 300 by other structures. The light guide 300 may have a plurality of light transmitting portions 220, and the light transmitting portions may be arranged at intervals, so that light having different degrees is divided into a plurality of light beams, and finally, a light emitting effect of multiple light effects is achieved. The light collecting member 200 may include a reflecting cup, a lens, etc. The light reflecting portion 210 may be located below the light transmitting portion 220 or above the light transmitting portion 220.

Further, referring to fig. 3 and 6, a reflective surface 110 is further disposed in the main body 100, the reflective surface 110 is disposed opposite to the light-transmitting portion 220, and the reflective surface 110 is configured to reflect the light emitted from the light-transmitting portion 220 to the light guide 300.

In the present embodiment, the position of the light guide 300 is not necessarily located within the light range emitted from the light transmitting portion 220, so the reflecting surface 110 can adjust the light path of the light emitted from the light transmitting portion 220. It is understood that the reflecting surface 110 may be disposed around the light collecting element 200, so as to correspond to the light guiding element 300 in the up-down direction, so as to ensure that each light guiding element 300 can receive light.

Further, referring to fig. 3 and 6, the light collecting member 200 concentrates the light of the light source 500 in a direction away from the bottom wall of the accommodating cavity, so as to form a first light path 10, and the light guiding member 300 is disposed through the main body 100 along the direction of the first light path 10.

In this embodiment, the direction away from the bottom wall of the accommodating cavity is the height direction, at this time, since the light guide 300 is penetrated in the main body 100 along the direction of the first light path 10, the directions of the first light path 10 and the second light path 20 are the same after exiting the light emitting structure, at this time, the light effects formed by the light emitting structure are adjacent, the light effect at the junction between the two layers of light effects is gradually changed, and the transition is gentle. Therefore, the situation that the user visually feels severe cracking and no gradual change is avoided between the double light effects.

Further, referring to fig. 1, 3,4 and 6, the light emitting structure further includes an anti-dazzle cover 400, the anti-dazzle cover 400 is disposed on a side of the light collecting element 200 away from the bottom wall of the accommodating cavity, and the light guiding element 300 is sleeved on an outer side wall of the anti-dazzle cover 400.

In this embodiment, the antiglare shield 400 may be connected to the upper end of the light collecting member 200, so as to improve the glare effect of the light emitted from the first light path 10, and make the light softer. And the light guide 300 may not be provided with the antiglare shield 400 since it receives only a part of the second optical path 20.

Further, referring to fig. 3 and 7, an arc-shaped groove 310 is disposed on a surface of the light guide 300 in the accommodating cavity, the arc-shaped groove 310 is recessed toward the outer side of the light guide 300, and the reflecting surface 110 is used for refracting the light passing through the light transmitting portion 220 to the arc-shaped groove 310.

In this embodiment, the light incident into the light guide 300 is generally concentrated in its light path, and in order to make the irradiation range of the light emitted from the light guide 300 wider, the light is softer, and the light incident into the light guide 300 needs to be dispersed. The arc-shaped groove 310 can shift the light path of the light after the light is incident on the light guide 300, thereby enlarging the irradiation range and softness of the light finally exiting the light guide 300.

Further, referring to fig. 6 and 8, an arc-shaped protrusion 320 is disposed on a surface of the light guide 300 located in the accommodating cavity, the arc-shaped protrusion 320 protrudes toward the outer side of the light guide 300, and the reflecting surface 110 is used for refracting the light passing through the light transmitting portion 220 to the arc-shaped protrusion 320.

In this embodiment, similar to the arc-shaped groove 310, the light incident into the light guide 300 can be dispersed or concentrated to make the irradiation range of the light guide 300 wider or narrower, and the light is softer or stronger. The arc-shaped protrusions 320 can deflect the light path after the light is incident to the light guide 300, so that the light path is concentrated and then enlarged, and finally the irradiation range and softness of the light emitted out of the light guide 300 are adjusted.

Further, referring to fig. 2, 7, 4 and 8, a plurality of microstructures 330 are disposed on a surface of the light guide 300 located outside the main body 100.

In this embodiment, since the light guide 300 is provided with the plurality of microstructures 330 on the outer side of the main body 100, the microstructures 330 may be a plurality of fine convex lines or a plurality of fine concave gaps. By virtue of the microstructure 330, when light is emitted from the surface of the light guide 300 located outside the main body 100, a single beam of light is dispersed into multiple beams, so as to achieve the light diffusion effect.

Further, referring to fig. 1 and 4, a heat sink 600 is disposed at a side of the bottom of the main body 100 opposite to the receiving cavity.

In the present embodiment, the heat sink 600 is provided at the bottom of the main body 100, so that the heat dissipation efficiency of the light emitting structure can be improved.

Further, referring to fig. 3 and fig. 6, the light emitting structure further includes a transparent bracket (not labeled in the drawings), the transparent bracket is located in the accommodating cavity, and the light collecting member 200 is connected to the light source 500 and is located in the transparent bracket;

the transparent support includes a parallel portion, which is disposed around the light-transmitting portion 220 and parallel to the light-transmitting portion 220.

In this embodiment, the transparent support is generally used to support the light collecting member 200, thereby improving the structural strength of the light emitting structure. Because the transparent support includes the parallel portion, and the parallel portion surrounds the light-transmitting portion 220, so the angle of the light emitted from the light-transmitting portion 220 is hardly changed, so that the light emitted from the light-transmitting portion 220 can be emitted to a preset position, and the light intensity of the second light path 20 is reduced due to the fact that part of the light cannot enter the light guide 300 after changing the angle is avoided.

Further, referring to fig. 3, the light source 500 is a lambertian illuminant;

The ratio of the luminous flux A of the light transmitting part 220 to the total luminous flux B emitted by the light emitting structure is 10-20%, and the included angle between the top of the light transmitting part 220 and the center of the light source 500 is 64-70 degrees.

In the present embodiment, since the light flux a of the light transmitting portion 220 is the light flux of the light of the second optical path 20, the total light flux B is the sum of the light fluxes of the first optical path 10 and the second optical path 20.

When the ratio of the luminous flux A to the luminous flux B is 10-20%, the lighting effect of the light-emitting structure can be ensured, and the atmosphere sense of double light effects is obvious.

According to the sphere integral formula of lightIn this formula, the number of the cells in the cell,For the light flux of the light source,The angle from the light emitted from the light source 500 to the bottom of the light-transmitting portion 220,The angle from the light emitted from the light source 500 to the top of the light-transmitting portion 220.In the actual production, which involves a process, it can be considered as 0 °. Since the light source 500 is a lambertian light source, referring to fig. 9,（）=cosWhereinIs thatWhen=0°, the luminous intensity (maximum value) of the lambertian illuminant is known to followIs of angle change, cos（) The value of (2) also changes gradually, and thus the specific luminous flux is not required in the present embodimentAny number may be substituted.

Similarly, since the specific size of the luminous flux does not need to be calculated in the embodiment, when the ratio of the luminous flux A to the total luminous flux B is calculated to be 10% -20%,Is of a size of (a) and (b). So in order to calculateThe method comprises the following steps:

first, the total luminous flux B is estimated, and substituted into the above sphere integral formula =0°，=90°, The total luminous flux B can be determined;

then, the value of the total luminous flux is adjusted to any value between 10% and 20%, for example, to 0.2b=luminous flux a;

substituting 0.2B again into the sphere integral formula, where the unknowns are only Therefore, it can be calculated=70°。

Similarly, can be foundWhen the light flux A is positioned between 64 degrees and 70 degrees, the value of the light flux A is 10 to 20 percent of the total light flux B.

In summary, the angle between the tip of the light-transmitting portion 220 and the center of the light source 500 can be confirmedIs in the range of 64 deg. to 70 deg..
