If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.
[0035] See also Figures 1 to 4 An embodiment of the present application provides a lighting device 100 , which includes a main body 10 , a light guide assembly 11 , a light-emitting element 12 , and a reflective element 13 .
[0036] The main body 10 includes a bottom plate 101, a side plate 102 and a mounting plate 103. The side plate 102 is arranged around the edge of the bottom plate 101 and extends along one side of the bottom plate 101. The bottom plate 101 and the side plate 102 are jointly arranged to form a receiving cavity 105. The mounting plate 103 is arranged at one end of the side plate 102 away from the bottom plate 101 and extends along one side of the side plate 102 toward the receiving cavity 105. The mounting plate 103 is arranged to form a light outlet 106 connected to the receiving cavity 105.
[0037] The light guide assembly 11 is matched with the mounting plate 103 and seals the light outlet 106. The light emitting element 12 is matched with the surface of the mounting plate 103 facing the mounting cavity. The reflective element 13 is disposed on the surface of the side plate 102 and the bottom plate 101 facing the mounting cavity.
[0038] It is understandable that, in the specific operation process of the lighting device 100, it is necessary to control the light emitting element 12 to emit light toward the accommodating cavity 105, and the light emitted by the light emitting element 12 is irradiated on the reflective element 13 arranged on the inner wall of the accommodating cavity 105, and is continuously refracted on the surface of the reflective element 13, so that the light is evenly transmitted in the accommodating cavity 105, and further guided to the outside through the light guide component 11. In this way, the lighting device 100 provided in the embodiment of the present application can guide and change the propagation direction of the light emitted by the light emitting element 12 in the accommodating cavity 105 through the reflective element 13, and make the light emitted by the light emitting element 12 propagate toward the light guide component 11 as much as possible, and can achieve a better uniform light transmission effect.
[0039] The specific style of the reflective member 13 is not limited. In some embodiments, the reflective member 13 is a film coated on the surface of the side plate 102 and the bottom plate 101 with a reflective material.
[0040] In other embodiments, the reflector 13 is a prefabricated reflective film made of reflective material. It is understandable that the reflector 13 is a prefabricated reflective film made of reflective material, which is conducive to rapid assembly, convenient replacement and maintenance, and saves manufacturing time and cost.
[0041] The specific type of the reflective material is not limited, for example, the reflective material is polycarbonate, acrylic, chlorinated rubber, etc.
[0042] In some embodiments, the reflective material in the reflective element 13 is nano-scale particles. It is understood that the nano-scale particles can be understood as particles with a size of 200 nm.
[0043] In the present application, the reflective film made of reflective material with nano-scale particles has the advantages of dense film layer and good film uniformity, so as to increase the reflectivity of light, thereby effectively reducing the loss of light and improving the brightness of light transmission.
[0044] In some embodiments, see Figure 2 and Figure 3 The light guide assembly 11 includes a light-transmitting plate 111, which is matched with the mounting plate 103 and seals the light outlet 106. It can be understood that the light-transmitting plate 111 can allow the light in the accommodating cavity 105 to pass through, so as to achieve a lighting effect.
[0045] The specific material of the light-transmitting plate 111 is not limited. For example, inorganic glass, organic polymer, and fiber and nano-composite materials. In some embodiments, the light-transmitting plate 111 is inorganic glass. It is understood that inorganic glass has good optical stability and high material transmittance, which can effectively improve the brightness of light transmission, and inorganic glass has wear resistance, which can improve the service life of the product.
[0046] In some embodiments, see Figure 1 and Figure 2 The light guide assembly 11 further includes a light guide 112, which is matched to the side of the light-transmitting plate 111 facing the installation cavity. It can be understood that the light guide 112 can evenly transmit the light in the accommodating cavity 105 to the light-transmitting plate 111 to achieve a uniform light transmission effect.
[0047] The specific material of the light guide 11211 is not limited. Optionally, the light guide 112 can be made of plastic materials such as PC (polycarbonate), PMMA (polymethyl methacrylate), PS (polystyrene), ABS (acrylonitrile butadiene styrene) by injection molding, and of course it can also be made of glass.
[0048] In some embodiments, see Figure 1 and Figure 2 The light guide 112 is made of ABS (Acrylonitrile Butadiene Styrene) material, which has high strength, good toughness, is easy to be thermoformed, and has good light guiding performance.
[0049] In some embodiments, see Figure 2 and Figure 4 The light emitting element 12 is used to emit light radially toward the bottom plate 101. In this way, the light emitted by the light emitting element 12 can illuminate the side plate 102 and the bottom plate 101 as much as possible, so that the reflective element 13 on the side plate 102 and the bottom plate 101 can evenly reflect the light and transmit it to the outside through the light guide assembly, thereby effectively improving the uniform light transmission effect of the lighting device 100.
[0050] In some embodiments, see Figure 1 and Figure 2 The main body 10 further includes a cover plate 104, which is disposed on a side of the light guide assembly 11 away from the mounting cavity and is detachably connected to the mounting plate 103. It is understandable that the user can disassemble and assemble the cover plate 104 according to actual needs.
[0051] Specifically, when the lighting device 100 needs to perform lighting operations, the cover plate 104 needs to be removed so that the light guide assembly 11 is exposed to the outside and can transmit light to the optical fiber to achieve a lighting effect. When the lighting device 100 does not need to perform lighting operations, the cover plate 104 needs to be assembled corresponding to the mounting plate 103 and cover the outside of the light guide assembly 11, thereby protecting the light guide assembly 11 and reducing the probability of damage to the light guide assembly 11.
[0052] In some embodiments, see Figure 1 and Figure 2 The light emitting element 12 includes a circuit board 121 and a light source 122 . The circuit board 121 is connected to the surface of the mounting plate 103 facing the mounting cavity. The light source 122 is connected to the surface of the circuit board 121 facing the mounting cavity and is electrically connected to the circuit board 121 .
[0053] The specific type of the light source 122 is not limited. In some embodiments, see Figure 1 and Figure 2 , the light source 122 is an LED lamp. It is understandable that the LED lamp has a better energy-saving effect, can effectively save the use cost and cost of the product, the LED lamp has a long service life, is not easy to damage, can effectively increase the service life of the flattening, the LED lamp uses a cold light source, has little glare, no radiation, does not produce harmful substances during use, and is conducive to improving the user experience.
[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
