DETAILED DESCRIPTION

[0036] The following description will be made in conjunction with the accompanying drawings. Figures 1-7 The application is further described in detail.

[0037] The embodiment of the application discloses a heat dissipation stage lamp.

[0038] Embodiment one

[0039] Referring to Figure 1 With Figure 2 , the heat dissipation stage lamp comprises a lamp body 1, and the lamp body 1 comprises a shell 2, the shell 2 is in a cylindrical structure and is provided with a mounting hole 21 extending along the length direction.

[0040] Referring to Figure 2 With Figure 3 , the lamp body 1 further comprises a light assembly 3 and a heat dissipation assembly 4, and the shell 2 is fixedly connected with a support plate 22, the support plate 22 is opposite to the hole opening of the mounting hole 21 and is used for supporting and fixing the light assembly 3. The light assembly 3 comprises an LED lamp plate and a control substrate for controlling the LED lamp plate, the control substrate is fixed to one side of the support plate 22 close to the hole opening of the mounting hole 21, the LED lamp plate is arranged at the position close to the hole opening of the mounting hole 21, and the LED lamp plate is located at the side of the control substrate away from the support plate 22.

[0041] Referring to Figure 2 With Figure 3The heat dissipation assembly 4 comprises a fan 41, which is arranged in the mounting hole 21 and located at the side hole of the mounting hole 21 away from the LED lamp plate, and the air outlet side of the fan 41 faces the support plate 22. During heat dissipation, the fan 41 is started to draw external air to form an air flow blowing to the support plate 22. The shell 2 is fixedly connected with a filter screen 5 (the filter screen 5 is marked in Figure 1 ), which comprises a plurality of regular hexagonal filter holes and is located at the side hole of the mounting hole 21 away from the LED lamp plate to filter the air drawn to the fan 41.

[0042] Referring to Figure 1 and Figure 3 , the shell 2 is fixedly connected with a flow guide plate 23, which is located at the side of the fan 41 away from the filter screen 5 and surrounds the fan 41 to form a flow guide space 24. The air flow blown by the fan 41 flows to the support plate 22 through the flow guide space 24, which guides the flow direction of the air flow and reduces the possibility of air flow spreading everywhere.

[0043] Referring to Figure 3 and Figure 4 , the flow guide plate 23 is fixedly connected with a plurality of connecting plates 231 on the outer wall and close to the bottom position, and the connecting plates 231 correspond to the outer side of the fan 41 away from the filter screen 5 (the filter screen 5 is marked in Figure 1 ). The connecting plates 231 and the outer side of the fan 41 are respectively provided with one-to-one corresponding and aligned through holes, and the connecting plates 231 and the fan 41 are provided with shock-absorbing nails 28, which are made of rubber material and have a certain elasticity.

[0044] Referring to Figure 4 , the shock-absorbing nail 28 comprises a nail rod 281, a first fixing block 282, a second fixing block 283 and a shock-absorbing ring 285. The first fixing block 282 is fixed to the end of the nail rod 281, the second fixing block 283 is fixed to the outer circumferential side of the nail rod 281 away from the first fixing block 282, the shock-absorbing ring 285 is fixed to the outer circumferential side of the nail rod 281 between the first fixing block 282 and the second fixing block 283, and the second fixing block 283 is inclined to form a guide surface 284. During installation, the shock-absorbing nail 28 is pressed through the through hole from the side of the connecting plate 231 to the side of the fan 41, at which time the guide surface 284 guides the second fixing block 283 to pass through the through hole. When the installation is completed, the first fixing block 282 abuts against the top of the connecting plate 231, the second fixing block 283 abuts against the shell of the fan 41 towards the side of the first fixing block 282, and the shock-absorbing ring 285 is located between the shell of the fan 41 and the connecting plate 231. The fan 41 and the flow guide plate 23 are connected by the shock-absorbing nail 28, and when the fan 41 is started to vibrate, the shock-absorbing ring 285 is used for shock absorption, which reduces the size of the vibration noise generated by resonance when the fan 41 is started.

[0045] Referring to Figure 3 With Figure 4 The outer peripheral side of the flow guide plate 23 and away from the fan 41 is fixedly connected with a sealing plate 232, the outer peripheral side of the sealing plate 232 abuts against the inner wall of the mounting hole 21, and the sealing plate 232 has a spacing with the support plate 22 and forms a heat dissipation space 25, which is communicated with the flow guide space 24. The airflow generated by the fan 41 enters the heat dissipation space 25 from the flow guide space 24 and then dissipates heat to the support plate 22.

[0046] Referring to Figure 2 With Figure 3 The heat dissipation assembly 4 further comprises heat dissipation plates 42, which are arranged in parallel and spaced apart in the horizontal direction in the heat dissipation space 25, and a heat dissipation channel 26 is formed between adjacent two heat dissipation plates 42. In order to increase the number of heat dissipation channels 26, the lengths of the heat dissipation plates 42 close to the middle part of the mounting hole 21 can be the same, and the lengths of the heat dissipation plates 42 away from the middle part of the mounting hole 21 on both sides can be the same, so that the length of the heat dissipation plate 42 is adapted to the width of the mounting hole 21, while reducing the production and installation difficulty of the heat dissipation plate 42. The two sides of the heat dissipation plate 42 respectively abut against the sealing plate 232 and the support plate 22, and the heat on the support plate 22 can be transmitted to the heat dissipation plate 42, which is conducive to increasing the heat dissipation area and improving the heat dissipation effect of the airflow. The housing 2 is provided with a plurality of air outlets 27 communicated with the heat dissipation channels 26, and the airflow flows into the heat dissipation channels 26 directly after flowing into the heat dissipation space 25 from the flow guide space 24. At this time, the airflow flows along the heat dissipation channels 26 to the air outlets 27 on both sides, and carries away the heat on the heat dissipation plates 42 and the support plate 22 during flowing, thereby realizing the heat dissipation effect.

[0047] Referring to Figure 3 The two ends of the heat dissipation plate 42 are respectively fixedly connected with contact plates 421 perpendicular to each other, and the contact plates 421 respectively abut against the support plate 22 and the sealing plate 232.

[0048] Referring to Figure 3 In addition to the contact plate 421 connected to the outermost heat dissipation plate 42, the other contact plates 421 abut against the adjacent heat dissipation plate 42 on the side away from the heat dissipation plate 42, which is conducive to the heat dissipation channel 26 formed by the two adjacent heat dissipation plates 42 being in a relatively uniform state, and reducing the possibility of turbulence caused by uneven airflow entering each heat dissipation channel 26 affecting the heat dissipation effect.

[0049] The implementation principle of the heat dissipation stage lamp according to the embodiment of the present application is as follows:

[0050] When the heat is dissipated, the fan 41 is started, at this time, the air flow outside is extracted by the fan 41 to the supporting plate 22 direction, the air flow flows through the guide space 24 first, then enters the heat dissipation space 25, and then is dispersed to each heat dissipation channel 26 after entering the heat dissipation space 25, at this time, the heat generated by the light assembly 3 is first received by the supporting plate 22, and then is transmitted to the heat dissipation plate 42, and after the air flow enters the heat dissipation channel 26, it flows to the two side air outlets 27, and carries away the heat on the supporting plate 22 and the heat dissipation plate 42 in the flowing process.
