Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a ceiling lamp. Background Art

[0002] A ceiling light is a type of lighting fixture. As the name suggests, it's called a ceiling light because its top is flat and attached to the ceiling during installation. Light sources include standard white bulbs, fluorescent lamps, high-intensity discharge lamps, halogen lamps, and LEDs. Ceiling lights are fixtures that are attached to or embedded in the ceiling. Like chandeliers, they serve as the primary lighting fixture in indoor spaces and are frequently used in homes, offices, entertainment venues, and other locations.

[0003] Some ceiling lights are often equipped with sensors, and different sensors can perform different functions. For example, infrared sensors can detect whether people pass under the ceiling light, and light sensors can detect the brightness below the ceiling light, thereby facilitating intelligent control of the ceiling light. Currently, sensors are usually placed on the side of the ceiling light's lampshade, close to the edge of the entire ceiling light. Due to possible obstructions from the lamp housing structure, such as the lampshade, the sensors may not work. If the sensor is placed in the middle of the lamp housing, the middle of the lamp housing will be dark when viewed from an angle, affecting the user's visual experience and making it less aesthetically pleasing.

[0031] See also Figure 1 and Figure 2 One embodiment of the present invention provides a ceiling lamp, including: a lamp housing 10, a light source assembly 20 and a sensor assembly 30.

[0032] See also Figure 1 、 Figure 2 and Figure 3 A boss 11 is provided in the middle of the lamp housing 10, and a reflective portion 12 is provided on the side of the boss 11 and arranged around the boss 11; a light source assembly 20 is provided on the lamp housing 10 and arranged around the boss 11; and a sensing assembly 30 is provided at the bottom end of the boss 11. By arranging the sensing assembly 30 at the bottom end of the boss 11 and being located in the middle of the lamp housing 10, there is less obstruction, which facilitates the sensing assembly 30 to accurately perform its sensing function. The light source assembly 20 is arranged around the boss 11, and the light emitted by the light source assembly 20 is reflected by the reflective portion 12 on the side of the boss 11, making it look like the boss 11 is emitting light, thus preventing the boss 11 from forming a dark portion on the lamp housing 10 that affects the appearance. The boss 11 is equivalent to a luminous structure, thereby preventing users from seeing a darker middle portion of the lamp housing 10 when observing from the side.

[0033] The specific structure of the light source assembly 20 can be appropriately designed according to actual needs. For example, the light source assembly 20 includes an annular substrate arranged around the boss 11 and a plurality of lamp beads arranged on the annular substrate. The plurality of lamp beads are evenly arranged around the boss 11.

[0034] The specific structure of the sensing component 30 can be appropriately designed according to actual needs. For example, the sensing component 30 includes an infrared sensor, which is arranged at the bottom end of the boss 11 located in the middle of the lamp housing 10 to facilitate the infrared sensor to emit and receive infrared rays; of course, the sensing component 30 can also use other types of sensors, such as ultrasonic sensors, light sensors, etc.

[0035] See also Figure 3 and Figure 4In some optional embodiments, in a vertical cross-section, the two sides of the reflective portion 12 gradually approach each other in the direction close to the bottom end of the boss 11. The light emitted by the light source assembly 20 is reflected by the reflective portion 12 and emitted toward the bottom and sides of the boss 11, thereby preventing the light emitted by the light source assembly 20 from being blocked by the boss 11, resulting in a dark area in the middle of the lamp housing 10, and making the light emitted by the ceiling lamp more uniform. As shown in the figure, it can be seen that the boss 11 appears to be glowing due to the reflection of the reflective portion 12, so that the user looking into the interior of the lamp housing 10 will find that there is no dark area inside the lamp housing 10, and the overall light emission is relatively uniform.

[0036] In some optional embodiments, in a horizontal cross-section, the cross-section of the reflective portion 12 is circular, so that the reflective portion 12 can reflect light more evenly and avoid the occurrence of blind spots and dark areas.

[0037] In some optional embodiments, in a vertical cross-section, the angle a between the reflective portion 12 and the horizontal plane is 20°-80°. In this embodiment, the angle a between the reflective portion 12 and the horizontal plane is 70°. Of course, the specific angle a between the reflective portion 12 and the horizontal plane can be adjusted according to the relative position and distance between the light source assembly 20 and the reflective portion 12, so that the reflective portion 12 can reflect light to a suitable angle.

[0038] In some optional embodiments, the light source assembly 20 and the sensor assembly 30 are detachably mounted on the lamp housing 10 , thereby facilitating disassembly, replacement, and maintenance.

[0039] In some optional embodiments, a light guide cavity 13 and an installation cavity 14 are formed on the lamp housing 10, the light source assembly 20 is installed in the light guide cavity 13, and the sensing assembly 30 is installed in the installation cavity 14, separating the light source assembly 20 and the sensing assembly 30 into two separate spaces for installation, thereby facilitating separate disassembly, assembly and maintenance of the light source assembly 20 and the sensing assembly 30, and avoiding the situation where the light source assembly 20 and the sensing assembly 30 are installed in the same space and connected to each other, resulting in the need to disassemble and install both the light source assembly 20 and the sensing assembly 30 at the same time when one of the light source assembly 20 and the sensing assembly 30 needs to be disassembled and repaired.

[0040] See also Figure 2 、 Figure 3 and Figure 5The specific formation method of the light guide cavity 13 can be selected according to actual needs. In some optional embodiments, the lamp housing 10 includes a base 15, a lampshade 16 and a boss 11. The boss 11 is arranged in the middle of the base 15. The lampshade 16 is detachably mounted on the base 15 and arranged around the boss 11. The light guide cavity 13 is formed between the base 15, the boss 11 and the lampshade 16. The light source assembly 20 is arranged on the base 15. Due to the reflection of the reflecting part 12 of the boss 11, there will be no dark area when the user observes the lampshade 16. The light emitted by the lampshade 16 is uniform and the lighting effect is good. The light source assembly 20 can be inspected and replaced by simply removing the lampshade 16 from the base 15.

[0041] The lampshade 16 can be assembled and disassembled with the base 15 through a snap-fit ​​structure or a threaded structure. For example, a snap-fit ​​piece is provided on the lampshade 16 , and a snap-fit ​​groove that snaps with the snap-fit ​​piece is provided on the base 15 .

[0042] The light source assembly 20 can be assembled and disassembled with the base 15 through a snap-fit ​​structure or a threaded structure. For example, the light source assembly 20 is provided with a plurality of screws that are threadably matched with the base 15 .

[0043] The sensing component 30 can be assembled and disassembled with the base 15 through a snap-fit ​​structure or a threaded structure. For example, the sensing component 30 is provided with a plurality of screws that engage with the inner wall threads of the installation cavity 14 .

[0044] In some optional embodiments, the mounting cavity 14 is formed in the boss 11, and other components such as the circuit board are placed in the mounting cavity 14, which is beneficial to utilizing the space inside the boss 11 and avoiding increasing the thickness of the base 15 in order to install other components such as the circuit board.

[0045] In some optional embodiments, the lampshade 16 has a bottom light-emitting surface 161 and a side light-emitting surface 162. The side light-emitting surface 162 is arranged around the boss 11, and the light source is located between the side light-emitting surface 162 and the reflective portion 12. The side light-emitting surface 162 facilitates expanding the range of light emitted by the lampshade 16. Moreover, when the mounting cavity 14 is formed in the boss 11, the base 15 can be designed to be thinner and the area of ​​the side light-emitting surface 162 can be designed to be larger. Therefore, when the user looks at the side of the lamp housing 10, the base 15 observed by the user accounts for a smaller proportion of the overall lamp housing 10, which makes the light-emitting portion of the lamp housing 10 appear larger and more beautiful.

[0046] In some optional embodiments, the mounting cavity 14 has an opening 141 located at the top of the boss 11. A cover 142 is detachably provided at the opening 141. The cover 142 seals the opening 141. By removing the cover 142, the sensing assembly 30 can be replaced or repaired through the opening 141. The cover 142 can be detachably connected to the base 15 or the boss 11 via a snap-fit ​​structure or a threaded structure.

[0047] In this embodiment, in order to facilitate the installation of the lamp housing 10, a mounting plate 40 is also provided on the top of the lamp housing 10. The mounting plate 40 can be fixed to a suitable location such as the ceiling. The lamp housing 10 and the mounting plate 40 are detachably connected through a snap-fit ​​structure or a threaded structure, which facilitates the disassembly, assembly and maintenance of the lamp housing 10.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
