Detailed Implementation

[0017] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that similar parts or functional components may be designated using the same numbers in the drawings. The drawings are merely intended to illustrate the embodiments of this disclosure and not to limit it. Those skilled in the art can derive alternative technical solutions from the following description without departing from the spirit and scope of this disclosure.

[0018] The embodiments of this disclosure are primarily described using lighting devices as examples. However, it should be understood that this disclosure does not limit the lighting devices to a specific form; for example, it does not limit the installation and fixing method of the lighting devices, nor does it limit the power supply method to rechargeable or plug-in. Those skilled in the art can make various modifications and changes to the embodiments by reading this specification and the accompanying drawings under the teachings of this disclosure. Any device defined within the spirit and scope of the appended claims should be considered a lighting device belonging to this disclosure. The various embodiments of this disclosure are described below in conjunction with the accompanying drawings.

[0019] Figure 1 An exploded perspective view of a lighting device 100 according to an embodiment of the present disclosure is shown. Figure 2 A cross-sectional view of a lighting device 100 according to an embodiment of the present disclosure is shown. Figure 5 A schematic diagram showing the connection and use of a lighting device 100 and a lamp 200 according to an embodiment of the present disclosure is shown.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, according to an embodiment of this disclosure, the lighting device 100 includes a first housing 110 and a second housing 160, which are connected to form a receiving space. In this disclosure, the first housing 110 is hemispherical, the second housing 160 is annular cup-shaped, and the receiving space formed by the connection of the first housing 110 and the second housing 160 is a spherical receiving space. This disclosure is not limited thereto; any housing that can provide a receiving space is included in this disclosure. The first housing 110 and the second housing 160 may also be integrally formed to provide the receiving space.

[0021] The second housing 160 includes a first opening and a second opening, the second opening facing the first housing 110, and the second opening and the first housing 110 are connected to form a receiving space. The second housing 160 also includes a first opening in the opposite direction to the second opening for connecting optical components.

[0022] The lighting device 100 also includes a bracket 120, fixed within the receiving space provided by the first housing 110 and the second housing 160. A light source plate 130 and a corresponding grid plate 170 are disposed on the bracket 120. In this embodiment, the light source plate 130 includes a plurality of LED light sources arranged in an array, i.e., the light source plate 130 includes an LED array; the grid plate 170 includes a plurality of grid units arranged in an array, i.e., the grid plate 170 includes a grid unit array. The plurality of grid units are correspondingly disposed to the plurality of LED light sources, where "correspondingly disposed" means that the plurality of grid units of the grid plate 170 separate the plurality of LED light sources from each other. In this way, the light emitted by the LED light sources towards each other is blocked by the grid units, thereby reducing or eliminating mutual interference between the LED light sources, improving the directivity of the light source, achieving a pixelated lighting effect, and thus facilitating the display of patterned lighting.

[0023] The height of the grille plate 170 is higher than the height of the multiple LED light sources in the light source plate 130, thereby effectively blocking the multiple LED light sources. Preferably, the height of the grille plate 170 in this disclosure is 1 cm to 5 cm.

[0024] In one embodiment, multiple LED light sources and multiple grille units are arranged in a one-to-one correspondence, but this disclosure is not limited thereto. In some embodiments, a single grille unit is provided with one or more LED light sources, thereby providing more sufficient light to each pixel.

[0025] In this embodiment, both the light source plate 130 and the grid plate 170 are connected to the bracket 120. This arrangement simplifies the process and improves production efficiency. Alternatively, the light source plate 130 and the grid plate 170 can be fixed to the first housing 110 or the second housing 160, respectively.

[0026] The lighting device 100 also includes optical components for providing the lighting effects requested by the user. For example... Figure 1 and Figure 2As shown, the optical assembly includes a frame 180 and a light-transmitting plate 190 connected to the frame 180. In this embodiment, the frame 180 of the optical assembly is connected to a first opening of the second housing 160 by screws, thereby closing the receiving space formed by the first housing 110 and the second housing 160. In other embodiments, the optical assembly may also be connected and fixed to the first housing 110 or the bracket 120. The optical assembly closes the receiving space and positions the light-transmitting plate 190 along a direction away from the receiving space. With this arrangement, the light-transmitting plate 190 can face the user and provide the desired ambient lighting according to the user's instructions.

[0027] The light-transmitting panel 190 is a colored light-transmitting panel, formed from materials including plastic, glass, or ceramic. The colored light-transmitting panel 190 is formed by adding a colored colorant. By providing the colored light-transmitting panel 190, the grid panel 170, the light source panel 130, and other components within the housing space of the lighting device 100 are effectively concealed. When the user observes the lighting device 100, only the light-transmitting panel 190, the first housing 110, and the second housing 160 are visible, thus providing a compact and aesthetically pleasing lighting device 100.

[0028] The colored colorant added to the light-transmitting plate 190 can be an organic colorant, including compounds such as azo compounds and anthraquinone compounds, or an inorganic colorant, including metal oxides such as iron oxide and manganese oxide. Preferably, the light-transmitting plate 190 in this embodiment is a brown-colored light-transmitting plate. When the lighting equipment 100 is in a power-off state, the light-transmitting plate 190 appears brown, which can effectively block the components inside the storage space.

[0029] In one embodiment, the light transmittance of the light-transmitting plate 190 is 10%-30%, and the haze is 45%-75%. By setting the light transmittance and haze of the light-transmitting plate 190, the lighting device 100 can provide clear patterned lighting with high pattern contrast and sharp edges. Simultaneously, the low light transmittance and certain haze ensure that the light-transmitting plate 190 effectively conceals the components inside the storage space when the lighting device 100 is powered off. In this embodiment, the haze of the light-transmitting plate 190 can be achieved by adding known haze modifiers such as silica and titanium dioxide, which are inorganic materials.

[0030] In this embodiment, the surface roughness of the light-transmitting plate 190 is not less than 0.1 micrometers and not more than 1.5 micrometers, preferably not less than 0.8 micrometers and not more than 1.5 micrometers, and can be achieved through processes such as electrical discharge machining, chemical etching, or mechanical processing. By treating the surface roughness of the light-transmitting plate 190, the specular reflection on the surface of the light-transmitting plate 190 can be further eliminated, making the surface of the light-transmitting plate 190 more uniform in the off state, and providing better shielding effect for internal components.

[0031] The lighting device 100 also includes a driver board 112, which is disposed within the receiving space. The driver board 112 is electrically connected to the light source board 130 to supply power to the light source board 130.

[0032] In one embodiment, the lighting device 100 further includes a sensing layer 140 for detecting user contact or tapping of the lighting device 100, and further controlling the lighting effects or pattern effects of the lighting device 100 based on the user's actions. Figure 1 As shown, the sensing layer 140 is a sensing copper foil, attached to the inner surface of the second housing 160. The sensing copper foil detects the user's touch or tapping action by sensing changes in capacitance, thereby controlling the lighting device 100.

[0033] Figure 3 The diagram shown is a rear perspective view of a lighting device 100 according to an embodiment of the present disclosure. Figure 4 and Figure 5 This is a schematic diagram illustrating the usage state of a lighting device 100 connected to a lamp 200 according to an embodiment of this disclosure. Figure 3 and Figure 4 As shown, the lighting device 100 also includes a charging interface 111. Preferably, the charging interface 111 is located on the side of the first housing 110 away from the receiving space. In one embodiment, the charging interface 111 is hidden within the first housing 110, i.e., the charging interface 111 does not protrude from the first housing 110. The charging interface 111 is used to connect the charging plug 220 and the connecting cable 210, thereby providing power to the lighting device 100. The other end of the connecting cable 210 is connected to the lamp 200, thereby powering the lighting device 100 through the lamp 200. This disclosure is not limited thereto; the connecting cable 210 can be directly connected to mains power or other drivers to power the lighting device 100.

[0034] Figure 6 The diagram shown is a schematic diagram of a charging interface 111 according to an embodiment of the present disclosure. Figure 7 The diagram shown is a schematic representation of a charging plug 220 according to an embodiment of the present disclosure. Figure 6 and Figure 7 As shown, the charging interface 111 includes a socket 1111 and protrusions 1112 on both sides of the socket 1111. Correspondingly, the charging plug 220 includes a connecting end 2201 and recesses 2202 on both sides of the connecting end 2201. The socket 1111 and the recesses 2202 are substantially the same in shape and size, thus allowing them to connect to each other. By providing the protrusions 1112 and the recesses 2202, the charging interface 111 and the charging plug 220 can be matched, preventing users from mistakenly connecting other charging plugs to the charging interface 111 and causing damage to the lighting equipment 100.

[0035] In one embodiment, a pair of protrusions 1112 are provided on both sides of the charging interface 111. This disclosure is not limited thereto. Providing a protrusion 1112 on one side of the charging interface 111 can also achieve the purpose of preventing misconnection in this disclosure, and is also included in this disclosure.

[0036] In this embodiment, protrusions 1112 are provided on both sides of the charging interface 111 to match the grooves 2202 of the charging plug 220. This disclosure is not limited thereto; a groove may also be provided on the charging interface 111 side and a corresponding protrusion may be provided on the charging plug 220 side to connect the charging interface 111 and the charging plug 220 and prevent the user from connecting an incompatible charging plug to the lighting device 100 and causing damage to the device.
