[0052] Embodiment 1:

[0053] As Figure 1 、 Figure 2 shown, Embodiment 1 of the present application provides a lampshade 100, including:

[0054] A first lens 110, the light incident surface of the first lens 110 is used to receive light, and the light emitting surface of the first lens 110 is used to emit light and reflect light;

[0055] A second lens 120, the light incident surface of the second lens 120 is used to receive light and reflect light, and the light emitting surface of the second lens 120 is used to emit light; the light incident surface of the second lens 120 is disposed opposite to the light emitting surface of the first lens 110.

[0056] By making both the light emitting surface of the first lens 110 and the light incident surface of the second lens 120 available for reflecting light and being disposed opposite to each other, after light is incident from the light incident surface of the first lens 110, it is reflected multiple times between the first lens 110 and the second lens 120 and passes through the second lens 120 multiple times, presenting an effect of thousands of layers of light on the light emitting surface of the second lens 120, increasing the number of layers of the thousand-layer lamp and showing clear hierarchical display.

[0057] The side where the light source is located is the light incident surface, and the side facing the illumination area is the light emitting surface.

[0058] Further, it includes: the light transmittance of the first lens 110 is 60% - 80%.

[0059] Further, it includes: the reflectance of the light emitting surface of the first lens 110 is 20% - 40%.

[0060] Transmittance: It represents the ability of light to pass through a medium, which is the percentage of the luminous flux passing through a transparent or translucent body to its incident luminous flux. The level of transmittance directly affects the transparency and visual effect of an object; Reflectance: It represents the proportion of light reflected on the surface of an object, usually expressed as a decimal or a percentage. Reflectance is equal to the ratio of the reflected light intensity to the incident light intensity, reflecting the light reflection ability of an object. Transmittance and reflectance are complementary to each other. The total amount of light incident on the surface of an object is affected by both, that is, the total light intensity is equal to the reflectance multiplied by the incident light intensity plus the transmittance multiplied by the incident light intensity. Therefore, an increase in reflectance will lead to a decrease in transmittance, and vice versa. The transmittance of the first lens 110 is the ratio of the intensity of the light emitted by the first lens 110 to the intensity of the received light. The reflectance of the light-emitting surface of the first lens 110 is the ratio of the intensity of the reflected light of the first lens 110 to the intensity of the received light.

[0061] The reflectance of the light-emitting surface of the first lens 110 is 20% - 40%, and at this time, the transmittance of the first lens 110 is 60% - 80%. When the transmittance of the first lens 110 is lower than 60%, the transmittance is too low, the display is unclear, and the clarity is poor. When the transmittance of the first lens 110 is higher than 80%, the transmittance is too high, the light source is exposed, and the external lamp beads are overly revealed.

[0062] Furthermore, it includes: The transmittance of the second lens 120 is 5% - 80%. The transmittance of the second lens 120 is the ratio of the intensity of the light emitted by the second lens 120 to the intensity of the received light.

[0063] Furthermore, it includes: The reflectance of the light-incident surface of the second lens 120 is 20% - 50%. The reflectance of the light-incident surface of the second lens 120 is the ratio of the intensity of the reflected light of the second lens 120 to the intensity of the received light.

[0064] The surface of the second lens 120 can be coated through physical vapor deposition technology, so that the transmittance of the second lens 120 is 30% - 70% and the reflectance is 30% - 70%.

[0065] In the specific design process, it is necessary to ensure that the brightness of each layer of light is decreasing and the layer spacing is appropriate and aesthetic. Whether the brightness is decreasing is related to the reflectance of the first lens 110 and the reflectance of the second lens 120.

[0066] The transmittance and reflectance of the first lens 110, and the transmittance and reflectance of the second lens 120 determine the clarity of the boundary sense between layers of the multi-layer lamp, which are important factors affecting the visual effect.

[0067] Tests on the transmittance value ranges of the first lens 110 and the second lens 120 (including the third lens 130) are shown in Table 1 below. Serial numbers 1, 2, and 3 are optimization tests on the transmittance of the first lens 110. At this time, the transmittance of the second lens 120 remains unchanged at 70%, and the transmittances of the first lens 110 are set to 60%, 70%, and 80% respectively. By observing the lighting presentation effect, when the transmittance of the second lens 120 remains unchanged, the visual effect is best when the transmittance of the first lens 110 is 70%.

[0068] Furthermore, serial numbers 4 and 5 are optimization tests on the transmittance of the second lens 120. The transmittance of the first lens 110 adopts the optimized result of tests 1-3, with a transmittance of 70%; then the transmittances of the second lens 120 are set to 49% and 81% respectively. The transmittance of the second lens 120 is 5% - 80%. At this time, the reflectance of the second lens 120 is 20% - 50%. Comparing synchronously with test 2, by observing the lighting presentation effect, when the transmittance of the first lens 110 is optimal, when the transmittance of the second lens 120 is less than 50%, although the number of displayed layers increases, the clarity of the boundary decreases and the visual effect becomes worse. When the transmittance of the first lens 110 is optimal, when the transmittance of the second lens 120 is greater than 80%, the number of displayed layers of the mille-feuille display decreases, the user experience becomes worse, and the visual effect of the dynamic display is reduced.

[0069] Table 1

[0070] Light transmittance First lens 110 Second lens 120 Visual effect 1 59％ 70％ The light transmittance is too low and it is not clear 2 70％ 70％ Optimal 3 81％ 70％ High-transmission lamp beads 4 70％ 49％ As the number of layers increases, the clarity of the boundary decreases 5 70％ 81％ The number of layers decreases

[0071] Furthermore, the first lens 110 includes a light-transmitting part and a light-shielding part. The transmittance of the light-transmitting part is greater than that of the light-shielding part, thereby ensuring that most of the light passes through the light-transmitting part, so that a pattern matching the shape of the light-transmitting part appears on the outer surface of the lampshade 100.

[0072] The light-transmitting part on the first lens 110 is a laser-engraved area, and the shape of the decorative part 140, such as a specific LOGO, can be laser-engraved. The light-transmitting part can transmit the light emitted by the light source.

[0073] The light-transmitting part and the light-shielding part can be separate or integral. When the light-transmitting part and the light-shielding part are separate, they can be connected by detachable means such as snap connection. In this way, mechanical connection between materials with different transmittances can be achieved, expanding the range of material selection and reducing the manufacturing difficulty. When the light-transmitting part and the light-shielding part are integral, the first lens 110 can be obtained by integral molding or fixed connection. At this time, there are requirements for the matching of materials and fixed connection methods, and there are also requirements for the integral molding process. The process is difficult, but the obtained first lens 110 has high strength and the final mille-feuille effect is clearer. Preferably, the light-transmitting part can use a laser method to outline the required pattern, and the surface of the light-shielding part can be aluminized to reduce its refractive index.

[0074] Further, it further includes a third lens 130, which is disposed on a surface of the second lens 120 away from the first lens 110.

[0075] The lamp shade uses the third lens 130 as the outer shell, which plays the roles of dust prevention and aesthetics. In addition, by setting the light transmittance of the third lens 130, the third lens 130 can further block the light emitted from the light-emitting surface of the second lens 120 to avoid the exposure of the internal structure. The light transmittance of the third lens 130 is 10% - 20%. If the light transmittance of the third lens 130 is lower than 10%, the luminous intensity outside the lamp shade 100 is small, affecting the effect; if the light transmittance of the third lens 130 is higher than 20%, the internal structure of the lamp shade 100 is exposed, reducing the viewing effect.

[0076] Further, it further includes a seal, which is disposed circumferentially on the third lens 130 to seal the lamp shade and the component to be installed. At the same time, the seal can also achieve buffering between the lamp shade 100 and other components at the lamp shade installation position. An example of the seal is a sealing strip.

[0077] Further, the difference between the first distance and the second distance is less than the difference threshold. The first distance is the distance between the third lens and the second lens, and the second distance is the distance between the first lens and the second lens.

[0078] The smaller the difference between the first distance and the second distance, the less obvious the sense of disconnection between the component to be decorated 140 and the light-emitting layer, making the multi-layer effect more delicate. Therefore, when the first distance is equal to the second distance, the multi-layer effect is the most realistic and delicate.

[0079] The ideal multi-layer effect is that the light brightness decreases and the layer spacing is appropriate. The decrease in light brightness can be obtained from a concentrated light source; as Figure 3 shown, the layer spacing is the distance in the first direction, including a first distance l1 and a second distance l2. Among them, the first distance l1 is the distance between the component to be decorated and the first light-emitting layer; the second distance l2 is the distance between adjacent layers after the first light-emitting layer. The first distance l1 is related to α and h3, and α is determined by L and h3. L is the distance between the light source and the boundary of the component to be decorated 140, which is related to the size of the component to be decorated 140 in the first direction. If the difference between the first distance l1 and the second distance l2 is too large, there will be a large difference in the distance between the first light-emitting layer and the subsequent light-emitting layers, thereby generating a sense of disconnection and affecting the viewing effect.

[0080] Further, it further includes a component to be decorated 140, which is disposed on a side of the second lens 120 away from the first lens 110.

[0081] The shape and material of the decorative part 140 should avoid internal refraction as much as possible, so as not to affect the light direction on the light-emitting side of the third lens 130 and prevent the occurrence of a halo phenomenon. The decorative part 140 can be planar or three-dimensional. When the decorative part 140 is three-dimensional, it is preferred to be arranged on the light-emitting surface of the third lens 130.

[0082] Furthermore, the decorative part 140 is connected to the second lens 120.

[0083] The lamp shade can also use the light-emitting surface of the second lens 120 as the outermost part to play a role in dust prevention and aesthetics. In addition, by setting the light transmittance of the second lens 120, the second lens 120 can further block the light of the light source 210 to avoid the exposure of the light source 210 and affect the aesthetics. At this time, the light transmittance of the second lens 120 is 5% - 50%. If the light transmittance of the second lens 120 is lower than 5%, the luminous intensity outside the lamp shade 100 is small, affecting the effect; if the light transmittance of the second lens 120 is higher than 50%, the internal structure of the lamp shade 100 is revealed, reducing the viewing effect.

[0084] The decorative part 140 is arranged on the light-emitting surface of the second lens 120, or the decorative part 140 and the second lens 120 are integrally designed (detachable connection, fixed connection, or integrated manufacturing is acceptable). The light transmittance of the decorative part 140 is less than that of the second lens 120 to ensure that the light-emitting surface of the second lens 120 at the non-decoration part 140 installation position can receive the light emitted inside the lamp shade 100, and then the multi-layer effect can be seen.

[0085] The arrangement of the decorative part 140 is based on the principle of not changing the light propagation form of the second lens 120. The light propagation form of the second lens 120 includes light transmission and reflection, that is, the reflectivity of the decorative part 140 on the side facing the light source 210 is as small as possible to reduce the influence on light and make the display between layers clearer.

[0086] Furthermore, it also includes a third lens 130, and the decorative part 140 is connected to the second lens 120 and / or the third lens 130.

[0087] The lamp shade uses the third lens 130 as the outer shell, which plays a role in dust prevention, aesthetics, and preventing the exposure of the internal structure. At the same time, the decorative part 140 can be connected to the second lens 120, connected to the third lens 130, or arranged between the second lens 120 and the third lens 130.

[0088] When the decorative part 140 is connected to the third lens 130, or arranged between the second lens 120 and the third lens 130 and connected to the third lens 130, the decorative part 140 can be arranged on the light-incident surface, inside, and / or light-emitting surface of the third lens 130.

[0089] The light transmittance of the to-be-decorated part 140 is less than that of the third lens 130, so as to ensure that the light-emitting surface passing through the third lens 130 at the non-installation position of the to-be-decorated part 140 can receive the light emitted inside the lamp cover 100, and then the multi-layer effect can be seen. Preferably, the light transmittance of the to-be-decorated part 140 is 80% - 90%.

[0090] The setting method of the to-be-decorated part 140 is based on the principle of not changing the light propagation form of the third lens 130. The light propagation form of the third lens 130 includes light transmission and reflection, that is, the reflectivity of the side of the to-be-decorated part 140 facing the second lens 120 is minimized to reduce the influence on light, so that the display between layers is clearer.

[0091] Further, as Figure 3 shown, the first lens 110 includes a light-transmitting part, and the shape of the light-transmitting part matches the shape of the to-be-decorated part 140.

[0092] The light-transmitting part of the first lens 110 has the same shape and size as the to-be-decorated part 140, and the light reaches the position of the second lens 120 after passing through the light-transmitting part. As Figure 3 shown, the primary light (represented by a straight line) passes through the second lens 120 and reaches the third lens 130, and then enters the human eye; the secondary light (represented by a dotted line) after being reflected by the second lens 120 reaches the first lens 110, and then is reflected by the first lens 110 to reach the second lens 120 and the third lens 130; the tertiary light (represented by a dash-dotted line) after being reflected by the second lens 120 reaches the first lens 110, and then is reflected by the first lens 110 to the second lens 120 and the third lens 130. So on and so forth, the light passes through and is reflected multiple times between the first lens 110 and the second lens 120, so that the light-emitting surface of the third lens 130 shows a pattern of layers overlapping with the same shape as the light-transmitting part.

[0093] Further, the to-be-decorated part 140 is a logo, which can play a role in emphasizing the logo with a clear identification, enhancing the brand communication power and influence, and enhancing the commercial value.

[0094] Embodiment 2:

[0095] As Figure 3 、 Figure 4 shown, Embodiment 2 of the present application provides a lamp 200, including the lamp cover 100 described above. The lamp 200 realizes the multi-layer light effect by adopting the lamp cover 100, and improves the recognition and high-class sense of the lamp 200.

[0096] Further, it further includes: a light source 210, which is connected to the lamp shade 100. The light source 210 is used to emit light towards the lamp shade 100, providing a light source for the lamp shade 100, so that the lamp 200 can emit light and present a thousand-layer light effect.

[0097] Further, the light source 210 includes a circuit board 211, and the circuit board 211 is used to connect to an external power supply 320.

[0098] Further, the circuit board 211 includes a light source 212, and the light source 212 is arranged on the circuit board 211. The light source 212 is used to emit light towards the lamp shade 100.

[0099] The circuit board 211 is provided with a light source 212, and the light source 212 includes at least one light-emitting point. When there are more light-emitting points, more dynamic displays can be achieved. For example, by adjusting some or all of the multiple light-emitting points to be turned on, the brightness can be adjusted; or by setting multiple light-emitting points to different colors and controlling the turning on or off of the light-emitting points of different colors according to requirements, different color changes can be achieved. The light-emitting point is any light source that can emit light, such as a commonly used LED lamp.

[0100] Multiple light-emitting points can also be respectively placed on multiple light-emitting plates for easy control. For example, 10 LED lamps are placed on 1 LED lamp board, and then the entire light source 212 is composed of 5 LED lamp boards. An LED lamp board means that LEDs are arranged and distributed on a panel to form a surface light source, and different patterns can be presented by controlling the turning on and off of different LEDs.

[0101] Further, the light source 210 further includes a lamp chamber 213, and the lamp chamber 213 is connected to the circuit board 211.

[0102] The circuit board 211 is arranged inside the lamp chamber 213, and the circuit board 211 is fixed to the lamp chamber 213 by snaps and screws, which plays a role in heat dissipation.

[0103] The lamp chamber 213 is connected to the third lens 130, and the connection method includes but is not limited to being connected by hot melt adhesive and / or structural parts. The structural part connection can be snaps, screw connections, welding, U-shaped nails, etc.

[0104] Embodiment 3:

[0105] As Figure 6 shown, Embodiment 3 of the present application provides a vehicle lamp control system 300, which includes a vehicle lamp controller 310 and the lamp 200 described above. The vehicle lamp controller 310 is connected to the lamp 200. The vehicle lamp controller 310 can enable the lamp 200 to achieve intelligent control and control the lamp 200 to have more functions.

[0106] Further, the vehicle lamp controller 310 is configured to: in response to a target requirement, control the display state of the lamp 200 so that the lamp 200 can be adjusted according to the target requirement, achieving intelligence.

[0107] Further, the display state of the lamp 200 includes: static display and dynamic display.

[0108] Static display means that the display screen of the lamp 200 remains unchanged within a certain period of time; dynamic display means that the display screen of the lamp 200 has at least two screens within a certain period of time.

[0109] Further, the dynamic display includes one or more of brightness change, color change, and change speed change.

[0110] Showing the effect of a breathing lamp through brightness change increases the fun and improves the user experience.
