[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] It is understandable that, referring to Figures 1 to 3 The ceiling lamp of the present invention includes a shell 100 and a lamp body 200. The shell 100 includes a metal shell 110 and a plastic shell 120. The metal shell 110 is installed in the plastic shell 120. Two mounting portions 130 are provided opposite to the plastic shell 120. The mounting portions 130 are used to be fixedly connected to the ceiling. The metal shell 110 is connected to a heat dissipation component 140 and a ventilation pipe 150. The heat dissipation component 140 includes a connecting plate 141, a baffle 142 and a plurality of heat dissipation fins 143. The connecting plate 141 abuts against the metal shell 110. The plurality of heat dissipation fins 143 are arranged at intervals. On the connecting plate 141, the connecting plate 141 is provided with a vent 144, and the vent 144 is arranged between two adjacent heat sinks 143. One end of the ventilation pipe 150 is connected to the vent 144, and the other end of the ventilation pipe 150 is connected to the outside of the ceiling. The inner diameter of the ventilation pipe 150 gradually decreases in the direction approaching the vent 144. The baffle 142 is connected to the upper end of the heat sink 143, and the baffle 142 is located above the ventilation pipe 150; the lamp body 200 is fixedly connected to the metal shell 110, and the lamp body 200 abuts against the heat sink 143, and the lamp body 200 is used to emit light.

[0027] The housing 100 includes a metal shell 110 and a plastic shell 120. The metal shell 110 is installed in the plastic shell 120. The lamp body 200 is fixedly connected to the metal shell 110. Two mounting parts 130 are arranged opposite to each other on the plastic shell 120. The plastic shell 120 is installed in the ceiling and fixed to the ceiling through the two mounting parts 130, so that the ceiling lamp can be stabilized on the ceiling, so that the lamp body 200 can emit light from the ceiling for illumination.

[0028] The connecting plate 141 is in contact with the metal shell 110, and multiple heat sinks 143 are arranged at intervals on the connecting plate 141. The heat generated by the lamp body 200 can be transferred to the heat sink 143 through the connecting plate 141. The heat sink 143 can accelerate the heat dissipation of the lamp body 200, reduce heat accumulation, and lower the temperature of the lamp body 200. In addition, the connecting plate 141 is provided with a ventilation hole 144, and the ventilation hole 144 is located between two adjacent heat sinks 143. One end of the ventilation pipe 150 is connected to the ventilation hole 144, and the other end is connected to the outside of the ceiling, so that air can enter from the outside of the ceiling to the inside through the ventilation pipe 150, thereby improving the fluidity of the air and allowing the air to flow over the multiple heat sinks 143. In addition, the inner diameter of the ventilation pipe 150 gradually decreases in the direction close to the heat sink 143, which can accelerate the flow speed of the air flow, allowing the air flow to smoothly flow through the wall surface of the heat sink 143, thereby improving the heat dissipation efficiency.

[0029] In addition, the baffle 142 is arranged at the upper end of the heat sink 143, and the baffle 142 is located above the ventilation pipe 150. The baffle 142 can prevent dust from falling on the heat sink 143, avoiding dust accumulation and clogging the ventilation pipe 150, so that the air flow can flow smoothly through the heat sink 143, thereby improving the heat dissipation efficiency and improving the reliability of the ceiling lamp.

[0030] It should be noted that the lamp body 200 includes a lamp bead 210, a lens 220 and a reflective cup 230 arranged in sequence. A through hole 231 is provided on the reflective cup 230. One end of the ventilation pipe 150 is connected to the vent 144, and the other end is connected to the through hole 231, so that air can enter from the through hole 231 and flow out from the vent 144 through the ventilation pipe 150, so that air can enter from the outside of the ceiling to the inside, thereby improving the heat dissipation efficiency of the ceiling lamp.

[0031] It is understandable that, referring to Figure 2 and Figure 3The plastic housing 120 is connected to a buckle 121, which is used to fix the connecting plate 141. The plastic housing 120 is connected to the buckle 121. The connecting plate 141 is placed on the buckle 121 and pressed to push the buckle 121 outward, so that the connecting plate 141 can be squeezed into the buckle 121. The buckle 121 is then reset, so that the buckle 121 can buckle the connecting plate 141 to the metal housing 110 to fix the position of the connecting plate 141, facilitating the installation of the connecting plate 141 without the need for fasteners, thereby improving the convenience of installation.

[0032] It should be noted that the metal shell 110 is installed in the plastic shell 120, the clip 121 is located at the end of the plastic shell 120 and above the metal shell 110, and the connecting plate 141 is arranged between the clip 121 and the metal shell 110. The connecting plate 141 can be fixed to the metal shell 110 through the clip 121, and the number of clips 121 is set to multiple. The cooperation of multiple clips 121 can fix the connecting plate 141 to the metal shell 110, thereby preventing the connecting plate 141 from falling off from the plastic shell 120 and improving the connection stability.

[0033] Specifically, refer to Figure 2 and Figure 3 The metal shell 110 is provided with a protruding positioning block 111, and the connecting plate 141 is provided with a positioning groove 145, in which the positioning block 111 is located. The metal shell 110 is provided with a protruding positioning block 111, and the connecting plate 141 is provided with a positioning groove 145. By setting the positioning block 111 to be located in the positioning groove 145, the positioning block 111 and the positioning groove 145 cooperate to locate the position of the connecting plate 141, preventing the connecting plate 141 from rotating, and allowing the vent 144 to remain connected to the vent pipe 150, thereby facilitating airflow and improving heat dissipation.

[0034] It should be noted that by aligning the positioning block 111 with the positioning slot 145 and then fastening the connecting plate 141 to the metal housing 110 via the buckle 121, the connecting plate 141 is prevented from rotating on the metal housing 110, thus preventing the vent 144 from misaligning with the ventilation tube 150. This allows airflow to be output from the vent 144 through the ventilation tube 150, thereby improving the heat dissipation efficiency of the ceiling lamp. Furthermore, the reflector cup 230 is fastened to the plastic housing 120 via the buckle 121, facilitating the positioning of the reflector cup 230 so that the through hole 231 can mate with the ventilation tube 150, facilitating airflow.

[0035] Specifically, refer to Figure 2 and Figure 4The metal housing 110 is fixedly connected to a magnetic block 112, which is used to attract the connecting plate 141. The magnetic block 112 is fixedly connected to the metal housing 110 and can attract the connecting plate 141, so that the connecting plate 141 can be stabilized on the metal housing 110, reducing the position of the connecting plate 141. The position of the connecting plate 141 can be shaken, so that the ventilation pipe 150 can be stably connected to the ventilation port 144, improving the flow stability of the gas and improving the reliability of the ceiling lamp.

[0036] It should be noted that the connecting plate 141 can be made of metal iron or nickel so that the magnetic block 112 can be attracted to the connecting plate 141. The number of magnetic blocks 112 can be set to multiple. The multiple magnetic blocks 112 can increase the attraction force on the connecting plate 141, making the connecting plate 141 stable on the metal housing 110 and improving the position stability of the connecting plate 141.

[0037] It is understandable that, referring to Figure 2 Thermal grease 146 is provided between the connecting plate 141 and the lamp body 200. The thermal grease 146 is provided between the connecting plate 141 and the lamp body 200. The thermal grease 146 can increase the contact area between the lamp body 200 and the connecting plate 141, and can accelerate the heat transfer of the lamp body 200, so that the heat can be smoothly transferred from the lamp body 200 to the connecting plate 141, facilitating the dissipation of the heat of the lamp body 200 through the heat sink 143, reducing the operating temperature of the lamp body 200, extending the service life, and improving the reliability of the ceiling lamp.

[0038] It is understandable that, referring to Figure 2 The plastic housing 120 includes a connecting tube 122 and a rib 123. The rib 123 is connected to the end of the connecting tube 122. The metal housing 110 is installed in the connecting tube 122. Two mounting portions 130 are arranged opposite each other on the connecting tube 122. The metal housing 110 is installed in the connecting tube 122. When the connecting tube 122 is installed in the ceiling, the two mounting portions 130 can drive the rib 123 to abut against the end surface of the ceiling, making the plastic housing 120 stable on the ceiling and improving the convenience of installation.

[0039] The outer contour of the retaining edge 123 is larger than that of the connecting tube 122 , and the connecting tube 122 can be installed in the ceiling so that the retaining edge 123 can abut against the end surface of the ceiling, thereby improving the connection stability.

[0040] Specifically, a retaining ring 124 is protruding from the inner wall of the connecting tube 122, and the metal shell 110 can abut against the retaining ring 124. The retaining ring 124 is provided on the inner wall of the connecting tube 122, and the metal shell 110 can abut against the retaining ring 124 to position the metal shell 110, so that the metal shell 110 can be stably positioned in the connecting tube 122, thereby improving the reliability of the ceiling lamp.

[0041] It should be noted that one end of the metal shell 110 abuts against the retaining ring 124, and the other end abuts against the buckle 121, so that the metal shell 110 can be positioned in the connecting tube 122, thereby preventing the metal shell 110 from shaking in the connecting tube 122 and improving the installation stability.

[0042] Specifically, refer to Figure 1 and Figure 2 The mounting portion 130 includes a support plate 131 and a torsion spring 132. The support plate 131 is rotatably connected to the connecting tube 122. The two ends of the torsion spring 132 respectively abut against the connecting tube 122 and the support plate 131, thereby driving the support plate 131 to rotate toward the sidewall 123. The support plate 131 is rotatably connected to the connecting tube 122. One end of the torsion spring 132 abuts against the connecting tube 122, while the other end abuts against the support plate 131. The torsion spring 132 can drive the support plate 131 to rotate toward the sidewall 123, so that the support plate 131 can drive the baffle 142 to abut against the end surface of the ceiling, allowing the ceiling lamp to be conveniently fixed to the ceiling without the need for fasteners, reducing damage to the ceiling and improving installation convenience.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
