[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 3 This utility model provides an ambient light, which includes a circuit board 1 and a light guide plate 2. The light guide plate 2 is attached to the circuit board 1 with an adhesive. The circuit board 1 is provided with a plurality of LED beads 3. The light guide plate 2 is provided with a plurality of lamp slots 21 arranged in an array. The LED beads 3 are correspondingly disposed in the corresponding lamp slots 21. The lamp slots 21 are used to limit the position of the LED beads 3, so that the LED beads 3 can emit light to the light guide plate 2 within the lamp slots 21, thereby achieving the display requirements of the ambient light.

[0026] Furthermore, the lamp bead 3 can be an LED device, which is an RGB three-color device. Through the circuit design of the circuit board 1 and the IC chip, the light color of the lamp bead 3 can be controlled, so that the lamp bead 3 can meet the light display requirements of the ambient light, thereby improving the user experience of the ambient light.

[0027] For details, please refer to the appendix. Figure 3 One side wall of the lamp slot 21 is set as a light-incident surface 212, and the light-emitting direction of the lamp beads 3 is towards the light-incident surface 212. The front of the light guide plate 2 is set as a display surface 23, and the light-incident surface 212 is perpendicular to the display surface 23. The ambient light can be a long strip-shaped lamp panel structure, with several lamp beads 3 arranged in a row on the lamp panel structure. The light-incident surface 212 is perpendicular to the display surface 23, so that the light-emitting direction of the lamp beads 3 is perpendicular to the display surface 23 of the light guide plate 2, avoiding the light emitted by the lamp beads 3 from directly illuminating the display surface 23 of the light guide plate 2, thereby avoiding the formation of light spots of the lamp beads 3 on the display surface 23 of the light guide plate 2, and ensuring the light emission effect of the ambient light.

[0028] Furthermore, the shape design of the ambient light can be adjusted according to the actual product application requirements, which will not be elaborated here.

[0029] Specifically, the surface of the circuit board 1 is provided with a reflective layer. The circuit board 1 is covered with a reflective layer at positions other than the LED beads 3, so that the circuit board 1 has a certain reflective effect. When the light guide plate 2 is attached to the circuit board 1, the reflective layer is attached to the bottom surface of the light guide plate 2. When the LED beads 3 emit light to the light guide plate 2, the reflective layer can increase the amount of light entering the light guide plate 2 and reduce the light loss inside the light guide plate 2, thereby improving the brightness of the ambient light.

[0030] Specifically, the light-incident surface 212 of the lamp groove 21 is provided with a sawtooth structure 211. The light-incident surface 212 refers to the plane where the inner wall of the lamp groove 21 is located in the light-emitting direction of the lamp bead 3. The sawtooth structure 211 can be understood as a shape feature added to the surface of the light-incident surface 212, which is used to change the transmission direction of the light emitted by the lamp bead 3 through the light-incident surface 212. When the lamp bead 3 is lit, the light emitted by the lamp bead 3 to the light guide plate 2 can enter the light guide plate 2 after passing through the sawtooth structure 211. Based on the sawtooth structure 211, the light-incident surface 212 of the light guide plate 2 can refract and reflect the incident light, improve the uniformity of the incident light on the light-incident surface 212 of the light guide plate 2, thereby improving the uniformity of the displayed light color of the ambient light.

[0031] Furthermore, the groove depth of the light guide plate 21 is h, and the value of h is in the range of 0.5mm≤h≤1.5mm. The groove length of the light guide plate is L, and the length of the lamp bead is L1. L and L1 satisfy L-L1>0.5mm. The groove width of the light guide plate 21 is W, and the width of the lamp bead 3 is W1. The values ​​of W and W1 satisfy W-W1>0.5mm. This allows the size of the light groove 21 to be adapted to the size and structure of the lamp bead 3, avoiding the overall size of the light groove 21 being too large, which would obstruct the light emitted by the lamp bead 3 and affect the light emission efficiency. At the same time, it can also avoid the overall size of the light groove 21 being too small, which would cause the light emitted by the lamp bead 3 to directly penetrate the light incident surface 212 of the light guide plate 2, failing to effectively change the light emission direction and affecting the light emission effect.

[0032] Furthermore, the distance between any two adjacent lamp slots 21 in the light guide plate 2 is D, and the value of D is in the range of 10mm≤D≤20mm. This ensures that the arrangement density of the lamp beads 3 can meet the light output display requirements of the ambient light and reduces the formation of dark areas due to insufficient distribution density of lamp beads 3 or the formation of light spots due to excessive distribution density of lamp beads 3, thereby ensuring that the ambient light has a good display effect.

[0033] Specifically, the side of the light guide plate 2 that is in contact with the circuit board 1 is provided with a plurality of recessed dot structures 22. The plurality of dot structures 22 extend from the bottom of the light guide plate 2 toward the interior of the light guide plate 2 and are arranged in an array. The dot structures 22 are used to improve the light refraction efficiency and reflection efficiency inside the light guide plate 2, so that the light output effect inside the light guide plate 2 is uniform, thereby improving the uniformity of the light output display of the ambient light and improving the display effect of the ambient light.

[0034] Furthermore, the dot structure 22 can be one of a cylinder, a hemisphere, or a cone. The shape design of the dot structure 22 inside the light guide plate 2 can be adjusted according to actual processing requirements to meet the display uniformity requirements of the ambient light.

[0035] Furthermore, when the dot structure 22 is a cylinder, the cylinder diameter of the dot structure 22 is d0, and the value range of d0 is 0.3mm≤d0≤1.0mm; the cylinder height of the dot structure 22 is h0, and the value range of h0 is 0.2mm≤h0≤0.6mm. This allows the dot structure 22 to meet the homogenization requirements of the light entering the interior of the light guide plate 2, thereby improving the uniformity and consistency of the light output efficiency of the light guide plate 2.

[0036] Specifically, the spacing between any two adjacent dot structures 22 is d, and the value of d ranges from 0.5mm to 2.0mm. The spacing d between two adjacent dot structures 22 can be one of 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, and 2.0mm. The distribution density of several dot structures 22 can be adjusted according to the size design of a single dot structure 22, so that the distribution of the dot structures 22 can meet the requirement of uniform light emission display.

[0037] Furthermore, the size design of a single dot structure 22 can adjust the light control performance of a single dot structure 22. When the distribution density of several dot structures 22 is low, a large dot structure 22 can be adapted to enhance the light output of a single dot and avoid uneven brightness in the ambient light. When the distribution density of several dot structures 22 is high, a small dot structure 22 can be adapted to prevent the ambient light from being locally too bright.

[0038] Specifically, the array of the dot structure 22 forms several blank areas, and one of the several light slots 21 is set in one of the blank areas. Through the arrangement design of the dot structure 22, the area on the light guide plate 2 other than the light slots 21 can reflect and refract light through the dot structure 22, thereby achieving the effect of brightening and improving the uniformity of light output.

[0039] Furthermore, by setting the blank area, the light concentration at the position of the light trough 21 can be reduced, thereby reducing the risk of light spots appearing at the position of the ambient light trough 21 and effectively improving the display effect of the ambient light.

[0040] Furthermore, the display surface 23 of the light guide plate 2 is provided with a textured structure, so that the display surface 23 of the ambient light achieves a uniform light emission effect, thereby improving the light emission efficiency of the ambient light.

[0041] Specifically, this utility model embodiment also proposes a home appliance, which includes a main body and an ambient light installed on the main body. The home appliance can be an air conditioner, refrigerator, washing machine, air purifier, or other household appliances. In this embodiment, an air conditioner is used as a specific example. The air conditioner includes a body and one or more air outlets installed on the body. The ambient light is installed at the air outlet position of the air conditioner. The structural outline of the ambient light can be adapted to the shape and contour of the air outlet of the air conditioner, so that the ambient light can meet the lighting display requirements of the air outlet position of the air conditioner, thereby improving the appearance display effect of the air outlet position of the air conditioner.

[0042] This utility model embodiment provides an ambient light. By setting a plurality of lamp slots 21 on the light guide plate 2, each lamp bead 3 on the circuit board 1 is correspondingly accommodated in the lamp slot 21. The use of side-emitting lamp beads 3 in conjunction with the light guide plate 2 with microstructure can improve the uniformity of light output of the ambient light. Moreover, the side-emitting lamp bead 3 structure can reduce the overall thickness design requirements of the light guide plate 2, effectively reduce the overall size and thickness of the ambient light, hide the light spot of the lamp bead 3, and improve the light output efficiency of the ambient light.

[0043] Furthermore, the above description provides a detailed overview of the ambient light and home appliance provided by the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
