However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0027] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0028] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0029] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0030] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0031] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. 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.
[0032] See also Figures 1 to 3 An embodiment of the present application provides a light-emitting device 100 , which includes a housing 10 and a light-emitting component 11 .
[0033] The housing 10 includes a mounting cavity 101 and a first opening 102 communicating with the mounting cavity 101 . The light emitting component 11 is mounted in the mounting cavity 101 .
[0034] It is understandable that the housing 10 covers the outside of the light emitting component 11, and can protect the light emitting component 11, so as to reduce the probability of damage caused by contact and collision between the light emitting component 11 and the outside, thereby effectively improving the service life of the product.
[0035] The light emitting assembly 11 includes a main body 111 , a light emitting member 112 and a light transmissive member 113 . A penetrating light emitting channel 1113 is formed in the main body 111 , and the inner wall of the light emitting channel 1113 extends in a zigzag manner.
[0036] It is understandable that the tortuous extension of the inner wall of the light-emitting channel 1113 can prevent the openings at both ends of the light-emitting channel 1113 from being directly connected in a single direction. In this way, during the specific operation of the light-emitting device 100, the inner wall of the light-emitting channel 1113 can block the propagation of the light emitted by the light-emitting component 112, and prevent the light emitted by the light-emitting component 112 from being directly transmitted to the light-transmitting component 113 according to the emission path, and then transmitted to the outside through the light-transmitting component 113, resulting in uneven light transmission. Specifically, during the specific operation of the light-emitting device 100, it is necessary to control the light-emitting component 112 to emit light toward the accommodating cavity, and the light emitted by the light-emitting component 112 is irradiated on the inner wall of the light-emitting channel 1113, and is continuously refracted on the inner wall surface of the light-emitting channel 1113, so that the light is evenly transmitted in the light-emitting channel 1113, and further guided out of the outside through the light-transmitting component 113. In this way, the light-emitting 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 component 112 in the light-emitting channel 1113 through the inner wall of the light-emitting channel 1113, and enable the light emitted by the light-emitting component 112 to propagate toward the light-transmitting component 113 as much as possible, and can achieve a better uniform light transmission effect.
[0037] The light-transmitting member 113 is connected to one end opening of the light-emitting channel 1113, and the light-emitting member 112 is connected to the other end opening of the light-emitting channel 1113 and is used to emit light of several different light waves into the light-emitting channel 1113. The end surface of the light-emitting component 11 connected with the light-transmitting member 113 coincides with the plane of the first opening 102.
[0038] It is understandable that the user can control the light emitting element 112 to emit light of a specific light wave into the light emitting channel 1113 according to actual needs to meet specific needs. For example, the user controls the light emitting element 112 to emit TL84 light into the light emitting channel 1113 so that the light emitted by the light emitting device 100 has a higher color rendering index and can provide better color reproduction, thereby meeting the needs of color matching work.
[0039] It is understandable that the type of light waves that can be emitted by the light emitting element 112 is not limited. Exemplarily, the user can also control the light emitting element 112 to emit sunlight into the light emitting channel 1113. The sunlight includes a full spectrum, and the full spectrum refers to a spectrum curve that includes ultraviolet light, visible light, and infrared light, and the ratio of red, green, and blue in the visible light part is similar to that of sunlight. The user controls the light emitting element 112 to emit sunlight into the light emitting channel 1113, which can be used to illuminate plants and promote plant growth.
[0040] In some embodiments, the light emitting assembly 11 further includes a reflector, which covers the inner wall of the light emitting channel 1113. It is understandable that the reflector can increase the reflectivity of light, thereby effectively reducing the loss of light and improving the brightness of light transmission.
[0041] The specific style of the reflective member is not limited. In some embodiments, the reflective member is a film coated on the inner wall surface of the light emitting channel 1113 with a reflective material.
[0042] In other embodiments, the reflective element is a prefabricated reflective film made of reflective material. It is understandable that the reflective element 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.
[0043] The specific type of the reflective material is not limited, for example, the reflective material is polycarbonate, acrylic, chlorinated rubber, etc.
[0044] The specific style of the main body 111 is not limited. In some embodiments, see Figure 2 and Figure 3 The main body 111 includes a first section 1111 and a second section 1112. The first section 1111 and the second section 1112 are each formed with a penetrating sub-channel. The first section 1111 and the second section 1112 are cross-arranged and interconnected to form a light-emitting channel 1113.
[0045] It is understandable that, during the specific operation of the light-emitting device 100, it is necessary to control the light-emitting component 112 to emit light toward the accommodating cavity, and the light emitted by the light-emitting component 112 will sequentially pass through the sub-channel of the first section 1111 and the sub-channel of the second section 1112 until it is guided out to the outside through the light-transmitting component 113. Among them, when the light emitted by the light-emitting component 112 is transmitted in the sub-channel of the first section 1111, it will irradiate the inner wall surface of the first section 1111 and continuously refract until it enters the sub-channel of the second section 1112; when the light is transmitted in the sub-channel of the second section 1112, it will irradiate the inner wall surface of the second section 1112 and continuously refract, and finally be guided out to the outside through the light-transmitting component 113. In this way, the light emitted by the light-emitting component 112 can be refracted multiple times in the light-emitting channel 1113, thereby achieving a better uniform light transmission effect.
[0046] In some embodiments, see Figure 1 and Figure 2 A side wall surface at the intersection of the first section 1111 and the second section 1112 is bent toward the light emitting element 112 to form a reflective surface 1114 .
[0047] It can be understood that the reflective surface 1114 is arranged opposite to the light emitting element 112, so that part of the light emitted by the light emitting element 112 can directly irradiate the reflective surface 1114, and the reflective surface 1114 can reflect the light irradiated thereon into the sub-channel of the first section 1111, so that the light irradiated thereon is again guided out of the outside through the sub-channel of the first section 1111, the sub-channel of the second section 1112 and the light-transmitting element 113. In this way, the refraction path of the light in the light-emitting channel 1113 can be further increased, so that the light is evenly transmitted in the light-emitting channel 1113, thereby achieving a better uniform light transmission effect.
[0048] In some embodiments, see Figure 2 and Figure 3 The light-emitting component 112 includes a circuit board and a plurality of light sources. The circuit board is connected to an opening at one end of the light-emitting channel 1113. All the light sources are connected to the surface of the circuit board facing the light-emitting channel 1113 and are electrically connected to the circuit board. Each light source is used to emit light of a preset light wave into the light-emitting channel 1113, and the preset light waves emitted by each light source are different.
[0049] It is understandable that the user can control different numbers or types of light sources to emit light according to actual needs, thereby combining light of different light waves so that the light-emitting device 100 can emit different types of light to meet different needs.
[0050] The specific type of light source is not limited. In some embodiments, see Figure 2 and Figure 3 All light sources are LED lamps. It is understandable that LED lamps have better energy-saving effects, which can effectively save the use cost and cost of products. LED lamps have a long service life and are not easy to damage. They can effectively increase the service life of the shovel. LED lamps use cold light sources, with little glare and no radiation. They do not produce harmful substances during use, which is conducive to improving user experience.
[0051] In some embodiments, see Figure 2 and Figure 3 The light emitting element 112 is used to emit light radially into the light emitting channel 1113. In this way, the light emitted by the light emitting element 112 can illuminate the side panels and the bottom panel as much as possible, so that the reflective elements on the side panels and the bottom panel 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 light emitting device 100.
[0052] The specific material of the light-transmitting plate is not limited, for example: inorganic glass, organic polymer, fiber and nano-composite materials, etc. In some embodiments, see Figure 1 and Figure 2, the light-transmitting member 113 is made of glass. It is understandable that glass has good optical stability and high material transmittance, which can effectively improve the brightness of light transmission, and glass has wear resistance, which can increase the service life of the product.
[0053] In some embodiments, see Figure 2 and Figure 3 The housing 10 further includes an air passage cavity 103, a second opening 104 and a third opening 105. The air passage cavity 103 is connected to a side of the mounting cavity 101 where a light-emitting component 112 is provided. The second opening 104 and the third opening 105 are connected to the air passage cavity 103 to form an air passage, and the light-emitting component 112 is located in the air passage.
[0054] It is understandable that one of the second opening 104 and the third opening 105 is used for air intake, and the other is used for air discharge. In this way, the airflow can flow through the air cavity 103 through the second opening 104 and the third opening 105, thereby taking away the heat generated by the light-emitting element 112 during operation, so as to cool the light-emitting element 112, which is beneficial to reduce the probability of damage of the light-emitting element 112 due to overheating, and can improve the service life and safety of the product.
[0055] In some embodiments, see Figure 1 and Figure 2 The light emitting device 100 further includes a cooling member 12, which is disposed in the air passage and is coupled to the light emitting member 112. It is understood that the cooling member 12 can further reduce the heat generated by the light emitting member 112 during operation, thereby reducing the probability of damage to the light emitting member 112 due to overheating, and can improve the service life and safety of the product.
[0056] In some embodiments, see Figure 2 and Figure 3 The housing 10 further includes a cable cavity 106, which is connected to the mounting cavity 101. The light emitting device 100 further includes a cable, which is fitted in the cable cavity 106, and one end of the cable is used to be electrically connected to the light emitting element 112, and the other end is used to be connected to a power source.
[0057] 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.
[0058] 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.
