DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0035] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0036] See also Figures 1 to 12 As shown, the utility model provides a bathroom heater (not shown), which is provided with a lighting module 100 and a host (not shown). The host is installed on the housing of the bathroom heater, and the lighting module 100 is arranged at the bottom of the host. The host outputs cold and warm air to the lighting module 100.
[0037] The lighting module 100 is applied to bathroom heaters and other electrical appliances, which are not limited here. In addition, the lighting module 100 can also be used alone. The lighting module 100 mainly includes a first light-emitting module 1, a second light-emitting module 2 and a lighting panel 3. The second light-emitting module 2 includes two optical cavities 21 arranged on the lighting panel 3. There is a gap between the two optical cavities 21, and the first lighting module 100 is located in the gap. The first light-emitting module 1 includes a light source component 11, an air guide plate 13 and a light guide component 14. The air guide plate 13 is pivotally connected to the lighting panel 3 and can rotate circumferentially relative to the lighting panel 3. The light guide component 14 is axially arranged on the air guide plate 13 and rotates with the rotation of the air guide plate 13; the light source component 11 is arranged on the axial end face of the light guide component 14, and is configured to emit light to the light guide component 14.
[0038] In this embodiment, during the rotation of the light guide 14, the light guide 14 is always located on the light emitting path of the light source 11, so that the light guide 14 can also obtain the light emitted by the light source 11 when rotating, and the light guide 14 continues to emit light when rotating, providing users with dynamically changing lighting effects, increasing the fun and interactivity of the product. The light guide 14 has a light emitting surface 142, and the light emitted by the light source 11 is emitted through the light emitting surface 142 of the light guide 14. The light can enter the light guide 14 from the side, and after internal reflection and refraction of the light guide 14, a wider range of lighting is achieved, that is, ambient light lighting is achieved through very few LED light sources. This setting enables the product to provide uniform and soft light in a larger space. Finally, uniform light emission is achieved, avoiding uneven light spots and brightness. By setting the light source 11 on the side of the light guide 14, a hidden light source design can be realized, making the product appearance more concise and beautiful. By providing the light source 11 on one side of the light guide 14 , the light of the light source 11 is transmitted to the light guide 14 , and the light guide 14 rotates along with the air guide plate 13 , thereby achieving a better ambient light effect.
[0039] Further, the first light-emitting module 1 also includes a driving assembly 12, and the driving assembly 12 includes a driving member 121 and a first transmission member 1211 connected to the output end of the driving member 121. The air guide plate 13 includes a pivot portion 132 and at least one wing portion 133 connected to the pivot portion 132. A second transmission member 131 is provided at the pivot portion 132, which is transmission-connected to the first transmission member 1211. The second transmission member 131 is specifically a gear. In other embodiments, it can also be replaced with parts with the same effect, which is not limited here. The second transmission member 131 is directly arranged on the air guide plate 13, which can reduce the need for a fixing member, simplify the overall structure and enhance the overall mechanical strength and stability. At the same time, since the second transmission member 131 is directly connected to the air guide plate 13, when the second transmission member 131 rotates, it can quickly and directly drive the air guide plate 13 to rotate, thereby improving the transmission efficiency. This direct drive method reduces the energy loss and friction in the transmission process, making the movement of the air guide plate 13 faster and more accurate. The first transmission member 1211 is meshedly connected with the second transmission member 131 , and the driving member 121 drives the air guide plate 13 to rotate through the first transmission member 1211 and the second transmission member 131 , so that the air guide plate 13 can rotate a certain angle according to actual needs.
[0040] Example 1
[0041] The pivot part 132 is provided with a mounting groove 134, and the light guide 14 is installed in the mounting groove 134. The lighting panel 3 is provided with a light source card groove 31, and the light source part 11 is carded in the light source card groove 31, and emits light toward the light guide 14 to realize the illumination of the middle part of the air guide 13. Alternatively, the light source part 11 is arranged at the pivot part 132 of the air guide 13, emits light to the light guide 14 from the side of the light guide 14, and rotates synchronously with the light guide 14 to realize the illumination of the middle part of the air guide 13. During the rotation of the light guide 14, the light emitted by the light source part 11 can also be transmitted to the light guide 14, so that the light guide 14 continues to emit light when rotating.
[0042] In this embodiment, the light source component 11 specifically includes an LED lamp bead and a substrate. The LED lamp bead is directly opposite to the light guide 14. The light emitted by the LED lamp bead can directly and effectively irradiate the light guide 14, reducing the loss and waste of light. The light guide 14 uses a light pipe, and the second transmission member 131 uses a gear. One end of the light guide 14 passes through the circular hole in the second transmission member 131 to further limit the light guide 14; in other embodiments, equivalent parts can also be selected, which is not limited here. If the distance between the light source component 11 and the light guide 14 is too far, the light guiding effect is not good, and part of the light will be wasted. If the distance is too close, the lamp bead on the surface of the light source component 11 will have temperature, and the end face of the light guide 14 will be baked yellow due to excessive temperature for a long time, reducing the light guiding performance. As a preferred embodiment, the distance between the light source component 11 and the light guide 14 is 0.2-0.5mm, which ensures that the light emitted by the light source component 11 can be efficiently coupled to the light guide 14, reducing the loss and waste of light. The design of this distance range takes into account the balance of thermal management and provides appropriate heat dissipation space, which helps to control the operating temperature of the LED lamp beads. At the same time, it avoids overheating of the end face of the light guide 14 due to too close a distance, thereby preventing the risk of the end face of the light guide 14 being baked yellow and extending the service life of the product.
[0043] Furthermore, the light source color of the light source 11 can be set accordingly according to different temperatures or states. The light source 11 uses RGB lamp beads or single-color lamp beads, and the light guide 14 can display any RGB mixed color. The light source 11 emits light of different colors according to the temperature and transmits it to the light guide 14. For example, when the host outputs warm air to the air guide plate 13, the light guide 14 is red or orange, and the color can be changed in other different modes.
[0044] Furthermore, the light guide 14 also includes a reflective surface 143, on which a microstructure 141 is provided, and the microstructure 141 is configured to reflect the light emitted by the light source 11 so that the light is emitted through the light emitting surface 142. Specifically, the microstructure 141 is a plurality of sawtooth structures 1411 protruding outward from the light guide 14, and the plurality of sawtooth structures 1411 are arranged along the radial direction of the light guide 14, and the cross-sectional area of any sawtooth structure 1411 is positively correlated with the distance from the sawtooth structure 1411 to the light source 11, thereby enhancing the overall uniformity of the light. The light is stronger at the first end 1412 close to the light source 11, and even if the cross-sectional area of the sawtooth structure 1411 used for reflection is small and the depth of the sawtooth structure 1411 is shallow, sufficient reflected light can be achieved. The light at the second end 1413 far from the light source 11 is weaker and requires a higher reflectivity; therefore, the sawtooth structure 1411 has a larger cross-sectional area and a deeper depth, which captures more light and reflects it, thereby increasing the reflectivity of the light. The sawtooth structure 1411 is distributed on the light guide 14 at different depths, compensating for the natural tendency of the light source intensity of the light source 11 to weaken as the distance increases, thereby achieving a uniform light effect.
[0045] The microstructure 141 includes a first end 1412 close to the light source 11 and a second end 1413 far from the light source 11, and the density of the sawtooth structure 1411 at the first end 1412 is less than the density of the sawtooth structure 1411 at the second end 1413. That is, the density of the sawtooth structure 1411 gradually increases from the first end 1412 to the second end 1413; the light reflection and scattering effect at the second end 1413 far from the light source is stronger, which helps to compensate for the attenuation of light intensity caused by the increase in distance. Therefore, even in an area far from the light source, sufficient light intensity can be maintained, thereby improving the overall utilization efficiency of light energy. It ensures that the light emitted from the light source 11 can be more evenly distributed when passing through the light guide 14, reducing brightness differences and the appearance of light spots. Preferably, there is at least one light source 11 between the first end 1412 and the second end 1413; when the length of the light guide 14 is shorter, a light source 11 is provided at one end of the light guide 14 to ensure the lighting brightness; when the length of the light guide 14 is longer, light sources 11 are provided at both ends of the light guide 14 to ensure the lighting brightness, and at this time the second end 1413 is located in the middle of the light guide 14.

Therefore, only the differences in structure are described here, and the same parts are not repeated.
[0048] In order to realize the illumination of both sides of the air guide plate 13, wings 133 are respectively provided on both sides of the air guide plate 13 adjacent to the pivot portion 132, and a mounting groove 134 is provided on the side of the wing 133 away from the pivot portion 132, and the light guide 14 is installed in the mounting groove 134. Specifically, the light source 11 is provided on the wing 133 of the air guide plate 13, emits light from the side of the light guide 14 to the light guide 14, and rotates synchronously with the light guide 14. During the rotation of the light guide 14, the light emitted by the light source 11 can also be transmitted to the light guide 14, so that the light guide 14 continues to emit light when rotating.
