In the actual application of the present application, this is not limited thereto.
[0044] This embodiment provides a corn lamp, which includes a lamp - head base 100, a radiator 110, a side lamp board 120, a top lamp board 160, a side lamp cover 130, a top lamp cover 170, and a light source 190. The lamp - head base 100 is used to connect to a power source. One end of the radiator 110 is installed on the lamp - head base 100. The side lamp board 120 is installed on the outer side surface of the radiator 110, and the top lamp board 160 is installed on the other end of the radiator 110. During use, the side lamp board 120 and the top lamp board 160 generate heat while emitting light. The radiator 110 can timely absorb and dissipate the heat to prevent the side lamp board 120 and the top lamp board 160 from being burned out. The side lamp cover 130 covers the side lamp board 120, and the top lamp cover 170 covers the top lamp board 160. The side lamp cover 130 and the top lamp cover 170 play a role in protection and dust prevention. The light source 190 is a surface light source and is respectively installed on the outer side surfaces of the side lamp board 120 and the top lamp board 160. The use of the surface light source for the light source 190 enables the light emitted by the light source 190 to be more uniform, improves the lighting performance of the corn lamp, and solves the problem of uneven light emission when a point light source is used for illumination.
[0045] In this embodiment, the radiator 110 is composed of a plurality of heat - dissipation plates 111 evenly distributed around the axis of the lamp - head base 100. The number of the side lamp boards 120 is the same as the number of the heat - dissipation plates 111. Further, the number of the heat - dissipation plates 111 is greater than or equal to three. During use, in order to achieve 360 - degree illumination, the number of the side lamp boards 120 needs to be greater than or equal to 3 to achieve full - range illumination, and the number of the heat - dissipation plates 111 cooperating with it is also greater than or equal to three.
[0046] In this embodiment, the radiator 110 is cylindrical. The radiator 110 is installed on the lamp - head base 100 and is set to be cylindrical, so that the radiator 110 occupies a small space, and the cylindrical shape can make the illumination range wide.
[0047] In this embodiment, the outer diameter of one end of the radiator 110 located at the lamp base 100 is larger than the outer diameter of the other end of the radiator 110. That is, when heat is generated during the light-emitting operation of the side light board 120 and the top light board 160 through the surface light source, the outer diameter of the radiator 110 located at one end of the lamp base 100 is larger than the outer diameter of the other end of the radiator 110. The larger outer diameter of the radiator 110 of the lamp base 100 can provide a larger heat dissipation space. Since hot air rises after being heated, it is easier for the generated heat to dissipate through the intervals and gaps on the radiator 110.
[0048] In this embodiment, the angle between the heat dissipation plate 111 and the axis of the connecting ring 140 is greater than or equal to 15 degrees and does not exceed 60 degrees. When the angle is 15 degrees, it reaches a minimum angle for easy heat dissipation. As the angle gradually increases, the heat dissipation effect will also increase. However, when the angle gradually increases, the heat dissipation plate 111 will gradually approach the lamp base 100, and the generated heat will also cause the temperature of the lamp base 100 to rise. To ensure that the temperature of the lamp base 100 is maintained without damaging the electrical components, the angle between the heat dissipation plate 111 and the axis of the connecting ring 140 should be ensured to be within 60 degrees.
[0049] In this embodiment, both ends of the plurality of heat dissipation plates 111 are fixed through the connecting ring 140, and the two connecting rings 140 are respectively located inside the heat dissipation plates 111. The connecting ring 140 fixes the upper and lower ends of the plurality of heat dissipation plates 111. And the two connecting rings 140 being respectively located inside the heat dissipation plates 111 can form a cavity inside the radiator 110, and the connecting ring 140 is annular. When gas exchange is required, heat can more easily enter from the inside of the lower connecting ring 140 to ensure heat dissipation. At the same time, the connecting ring 140 being located inside the heat dissipation plates 111 can also ensure that both sides of the heat dissipation plates 111 are not blocked, further ensuring heat dissipation.
[0050] There is an interval between two adjacent heat dissipation plates 111, and the radiator 110 between the two connecting rings 140 is of a hollow structure. Through the spaced arrangement of the heat dissipation plates 111 and the hollow structure of the radiator 110, the heat generated by the side light board 120 and the top light board 160 can be more easily dissipated.
[0051] According to Figure 2-4 As shown, in this embodiment, the heat dissipation plate 111 is a straight strip plate. When a plurality of heat dissipation plates 111 are fixed together to form the radiator 110, since the heat dissipation plate 111 is a straight strip plate and the outer diameter of one end of the radiator 110 located at the lamp base 100 is larger than the outer diameter of the other end of the radiator 110, the interval between two adjacent heat dissipation plates 111 at the end of the radiator 110 located at the lamp base 100 will be larger; at the same time, it also makes the internal space above larger. Without affecting the lighting area, when heat flows, it is easier to dissipate.
[0052] According toFigure 5 As shown, in this embodiment, the heat dissipation plate 111 is an arc-shaped plate with its center facing the axis of the lamp socket 100. When multiple arc-shaped plates form a radiator 110, the shape of the radiator 110 is semi-ellipsoidal or hemispherical. While maintaining that the outer diameter of one end of the radiator 110 located at the outer edge of the lamp socket 100 is greater than the outer diameter of the other end of the radiator 110 to facilitate heat dissipation, when the side lamp plate 120 is fixed on the arc-shaped plate, the bending of the side lamp plate 120 makes the light transition effect better when the light is irradiated, and at the same time, the curved shape is more aesthetically pleasing.
[0053] According to Figure 3 、 8 As shown, a tapered block 150 is installed on the lamp socket 100. The tip of the tapered block 150 faces the top lamp plate 160. When the lamp socket 100 is installed and fixed to the radiator 110, there is a gap between the tapered block 150 and the radiator 110. Adding the tapered block 150 can increase the thickness of the lower end of the lamp socket 100, making it difficult for heat to transfer into the lamp socket 100; and because the tip of the tapered block 150 faces the top lamp plate 160, when the heat generated by the radiator 110 flows upward, the generated heat gas will be diverted outward by the tapered block 150, so that heat will not accumulate at the connection position between the lamp socket 100 and the radiator 110, improving the heat dissipation effect.
[0054] Please refer to Figure 1-3 As shown, the lamp socket 100 includes a lamp base 101 and a connecting plate 102, and the connecting plate 102 is installed with the connecting ring 140.
[0055] An annular plate 180 is installed on the outer edge of the connecting plate 102, and there is a gap between the annular plate 180 and the upper side of the radiator 110. That is, there is an annular plate 180 outside the connecting ring 140 where the radiator 110 is located. The annular plate 180 is provided to prevent dust from falling into the radiator 110 through the gaps after long-term use, and the annular plate 180 blocks the dust from falling. The cross-section of the annular plate 180 is a cone facing outward, and during the heat dissipation process, the annular plate 180 does not block the heat from dissipating outward.
[0056] Please refer to Figure 3 As shown, the lamp base 101 includes a metal screw head 10a, a lamp cover 10b, a circuit board 10c, and a connecting cover plate 10d. The lamp base 101 is installed with the power supply through the metal screw head 10a, the circuit board 10c is installed in the lamp cover 10b, the connecting cover plate 10d covers the circuit board 10c, and the connecting plate 102 is installed on the side of the lamp cover 10b close to the connecting cover plate 10d.
[0057] Please refer to Figure 3As shown, the ceiling lamp board 160 and the ceiling lamp cover 170 are annular. The ceiling lamp board 160 and the ceiling lamp cover 170 are both installed on the connecting ring 140 at the end far from the lamp socket 100. The middle of the connecting ring 140 is breathable, and gas flows in from the middle of the connecting ring 140.
[0058] According to Figure 2-5 As shown, the inner cross-section of the heat dissipation plate 111 is tree-shaped, which can increase the contact area with air. At the same time, it can also make heat more easily absorbed and dissipated, achieving a good heat dissipation effect.
[0059] The side lamp cover 130 and the ceiling lamp cover 170 can transmit light.
[0060] The utility model provides a corn lamp. By using surface light sources on the side lamp board and the ceiling lamp board, the emitted light can be made more natural, achieving the effect of uniform illumination and ensuring the performance of the LED corn lamp.
[0061] After multiple heat dissipation plates are fixed together to form a radiator, the outer diameter of the radiator at the end of the lamp socket is larger than the outer diameter of the other end of the radiator. The distance between two adjacent heat dissipation plates at the end of the lamp socket will become larger, and at the same time, the internal space here is larger. When heat flows upward, it is easier to dissipate. At the same time, by using the internal tapered block, when the heat generated by the radiator flows upward, the generated heat gas will be diverted outward by the tapered block, so that the heat will not accumulate in the middle of the upper end of the radiator, further improving the heat dissipation effect.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
