An automated luminaire integrated heat dissipation system

Abstract

This utility model discloses an automated integrated heat dissipation system for lighting fixtures. The beneficial effects are as follows: When the lighting fixture is continuously operating, the thermochromic contact in the temperature-sensitive sealing component expands upon heating, causing the sealing block to open. Once open, the heat accumulated inside the sealed enclosure is expelled through a one-way exhaust valve and exhaust pipe. Meanwhile, cooler air from the external environment enters the sealed enclosure through the intake pipe and one-way intake valve, allowing airflow outside the lighting fixture and achieving automatic heat dissipation. When the temperature inside the sealed enclosure decreases, the thermochromic contact returns to its original position, causing the sealing block to seal the interface between the sealed enclosure and the intake and exhaust pipes, stopping the airflow. When the external ambient temperature is low, the heat emitted by the lighting fixture inside the sealed enclosure is conducted into the room through the vents, thus fully utilizing the heat generated by the lighting fixture.

Description

Technical Field

[0001] This utility model relates to the field of lighting heat dissipation technology, specifically to an automated integrated lighting heat dissipation system. Background Technology

[0002] In order to ensure that indoor lighting fixtures can provide continuous illumination during long-term operation, it is necessary to dissipate the heat generated during operation in a timely manner.

[0003] Currently, the main method for heat dissipation of indoor lighting fixtures is to use the heat dissipation fins of the lighting fixture itself in conjunction with an active ventilation system. While this method can achieve heat dissipation, the active ventilation system consumes a lot of energy and requires manual control of the ventilation system, resulting in delays in continuous lighting. It also leads to poor environmental performance. Furthermore, the heat emitted by the lighting fixtures in cold environments is directly discharged into the external environment, making it impossible to effectively utilize the heat generated by the lighting fixtures. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide an automated integrated heat dissipation system for lighting fixtures that can automatically dissipate heat from lighting fixtures by utilizing the chimney principle and fully utilize the heat generated by lighting fixtures when the external ambient temperature is low.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes an automated integrated heat dissipation system for lighting fixtures, including a ceiling, on which lighting fixtures are installed. A sealing cover is installed on the ceiling outside the lighting fixtures. An air inlet pipe connected to the external environment is installed in the middle of one side wall of the sealing cover. A normally open one-way air inlet valve is installed at the air outlet of the air inlet pipe. An exhaust pipe is installed on the side wall of the sealing cover opposite to the air inlet pipe. A one-way exhaust valve is installed at the air inlet of the exhaust pipe. A temperature-sensing sealing assembly is installed in the sealing cover at the connection points with the air inlet pipe and the exhaust pipe, respectively. The temperature-sensing sealing assembly includes a linkage rod, a sealing block, a temperature-changing contact plate, a supporting side plate, and a connecting column. Ventilation holes are opened on the ceiling outside the lighting fixtures.

[0008] Furthermore, the sealing cover is bolted to the ceiling, and both the air intake pipe and the exhaust pipe are welded to the sealing cover.

[0009] Furthermore, the housing of the one-way intake valve is bolted to the one-way intake pipe, and the housing of the one-way exhaust valve is bolted to the exhaust pipe.

[0010] Furthermore, the ventilation holes extend through the ceiling, and the lighting fixtures also extend through the ceiling.

[0011] Furthermore, there are two supporting side plates, and two arc-shaped temperature-sensitive contact pieces are installed between the two supporting side plates in a symmetrical manner.

[0012] Furthermore, each of the temperature-sensitive contact pieces is connected to a linkage rod on one side, and the end of the linkage rod facing away from the temperature-sensitive contact piece is connected to the sealing block.

[0013] Furthermore, the supporting side plate is made of stainless steel, one end of the connecting column is welded to the supporting side plate, and the other end of the connecting column is welded to the sealing cover.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention utilizes the expansion of the temperature-sensitive sealing contact in the temperature-sensitive sealing component when the lighting fixture is continuously operating to open the sealing block. After the sealing block opens, the heat accumulated inside the sealed cover is discharged through the one-way exhaust valve and exhaust pipe. Meanwhile, the cooler air from the external environment enters the sealed cover through the air inlet pipe and one-way air inlet valve, allowing airflow outside the lighting fixture and achieving automatic heat dissipation. When the temperature inside the sealed cover drops, the temperature-sensitive contact will return to its original shape and deform, thereby causing the sealing block to seal the interface between the sealed cover and the air inlet and exhaust pipes, stopping the airflow. When the external ambient temperature is low, the heat emitted by the lighting fixture inside the sealed cover is conducted into the room through the vent, thus making full use of the heat generated by the lighting fixture.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3 As shown in the illustration, an automated integrated heat dissipation system for lighting fixtures in this embodiment includes a ceiling 2, on which a lighting fixture 3 is installed. A sealing cover 5 is installed on the ceiling 2 outside the lighting fixture 3. An air inlet pipe 1 connected to the external environment is installed in the middle of one side wall of the sealing cover 5. A normally open one-way air inlet valve 6 is installed at the air outlet of the air inlet pipe 1. An exhaust pipe 4 is installed on the side wall of the sealing cover 5 opposite to the air inlet pipe 1. A one-way exhaust valve 8 is installed at the air inlet of the exhaust pipe 4. A temperature-sensing sealing assembly 9 is installed in the sealing cover 5 at the connection points with the air inlet pipe 1 and the exhaust pipe 4, respectively. The temperature-sensing sealing assembly 9 includes a linkage rod 901, a sealing block 902, a temperature-sensitive contact 903, a supporting side plate 904, and a connecting column 905. A vent 7 is opened on the ceiling 2 outside the lighting fixture 3. When the lighting fixture 3 is continuously working, the vent 7 is used to vent the lighting fixture 3. The expansion of the thermosensitive contact 903 in the temperature-sensitive sealing component 9 upon heating causes the sealing block 902 to open. After the sealing block 902 opens, the heat of the lighting fixture 3 accumulated inside the sealing cover 5 is discharged through the one-way exhaust valve 8 and the exhaust pipe 4. Meanwhile, the cooler air in the external environment enters the sealing cover 5 through the air inlet pipe 1 and the one-way air inlet valve 6, allowing the air outside the lighting fixture 3 to flow and achieve automatic heat dissipation for the lighting fixture 3. When the temperature inside the sealing cover 5 drops, the thermosensitive contact 903 will reset and deform, thereby causing the sealing block 902 to seal the interface between the sealing cover 5 and the air inlet pipe 1 and the exhaust pipe 4, thus stopping the airflow process. When the external ambient temperature is low, the heat emitted by the lighting fixture 3 inside the sealing cover 5 will be conducted into the room through the vent 7, thereby making full use of the heat generated by the lighting fixture 3.

[0024] like Figures 1-3As shown in the figure, in this embodiment, the sealing cover 5 is bolted to the ceiling 2, and the air inlet pipe 1 and the exhaust pipe 4 are both welded to the sealing cover 5. The ceiling 2 mainly provides the installation base for the lighting fixture 3. The sealing cover 5 allows the heat emitted by the lighting fixture 3 to be concentrated in one space. The housing of the one-way air inlet valve 6 is bolted to the one-way air inlet pipe 1, and the housing of the one-way exhaust valve 8 is bolted to the exhaust pipe 4. The one-way air inlet valve 6 can ensure that external gas enters the sealing cover 5 in one direction, and the one-way exhaust valve 8 can ensure that the hot air inside the sealing cover 5 is discharged to the outside in one direction. The vent 7 penetrates the ceiling 2, and the lighting fixture 3 penetrates the ceiling 2. The vent 7 can allow the heat inside the sealing cover 5 to dissipate into the room when the ambient temperature is low, so as to make full use of the heat generated by the lighting fixture 3.

[0025] like Figures 1-3 As shown, in this embodiment, there are two supporting side plates 904. Two arc-shaped thermochromic contact pieces 903 are symmetrically installed between the two supporting side plates 904. The thermochromic contact pieces 903 expand and deform upon heating, changing from an inwardly concave state to an outwardly convex state. Simultaneously with this deformation, the thermochromic contact pieces 903 move the sealing block 902 via a linkage rod 901. Each thermochromic contact piece 903 is connected to a linkage rod 901 on one side. A sealing block 902 is connected to one end of rod 901 facing away from the thermocouple 903. The sealing block 902 is mainly used to seal the openings at the connection between the sealing cover 5 and the air inlet pipe 1 and the exhaust pipe 4 as needed. The support side plate 904 is made of stainless steel. One end of the connecting column 905 is welded to the support side plate 904, and the other end of the connecting column 905 is welded to the sealing cover 5. The support side plate 904 provides the thermocouple 903 with an installation base, while the connecting column 905 ensures that the support side plate 904 is stably installed inside the sealing cover 5.

[0026] The specific implementation process of this embodiment is as follows: First, the device is installed at the corresponding position on the indoor ceiling, and both the air inlet pipe 1 and the exhaust pipe 4 are connected to the external environment. Then, the lamp's heat dissipation system can be put into use. During use, when the lighting fixture 3 is continuously working, the expansion of the temperature-sensitive sealing component 903 after heating causes the sealing block 902 to open. After the sealing block 902 opens, the heat accumulated in the sealing cover 5 of the lighting fixture 3 is discharged through the one-way exhaust valve 8 and the exhaust pipe 4, while the lower temperature air in the external environment... The air body enters the sealed cover 5 through the air intake pipe 1 and the one-way air intake valve 6, allowing the air outside the lighting fixture 3 to flow and achieve automatic heat dissipation for the lighting fixture 3. When the temperature inside the sealed cover 5 drops, the temperature-sensitive contact 903 will reset and deform, thereby driving the sealing block 902 to seal the interface between the sealed cover 5 and the air intake pipe 1 and the exhaust pipe 4, so as to stop the air flow process. When the external ambient temperature is low, the heat emitted by the lighting fixture 3 inside the sealed cover 5 will be conducted into the room through the vent 7, thereby making full use of the heat generated by the lighting fixture 3.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
