Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lighting equipment, and in particular to a high-power matrix lighting fixture. Background Art
[0002] With the rapid development of LED technology, high-power LED lighting fixtures have been widely used in industrial, commercial and public lighting. However, these lamps generally face the problem of low heat dissipation efficiency during use. The traditional heat dissipation method mainly relies on the natural convection of the heat sink, that is, the heat is transferred to the air through the metal heat sink, and then the heat is taken away by the natural flow of air. However, high-power LED chips generate a lot of heat when working, and natural convection alone cannot meet its heat dissipation needs.
[0003] Inefficient heat dissipation will cause the temperature of the LED chip to rise, exceeding its optimal operating temperature range. This will not only reduce the luminous efficiency of the LED and weaken the light output, but also accelerate light aging and shorten the service life of the LED. Excessive temperature may even cause permanent damage to the LED chip, affecting the reliability and safety of the lamp.
[0004] In addition, in terms of air flow, traditional designs often ignore the principles of aerodynamics. The arrangement and shape of the heat sink do not fully consider the path and speed of air flow, resulting in air stagnation areas around the heat sink. Hot air cannot be taken away in time, and fresh cold air is difficult to replenish in time, resulting in heat accumulation. This poor air flow further reduces the heat dissipation efficiency and makes the lamp prone to overheating risks. Summary of the invention

[0030] A hoisting table 126 is arranged above the top guide cover plate 119, and an adaptation chamber 130 is fixed on the hoisting table 126. A drive motor 128 is fixed on the adaptation chamber 130, and the output shaft of the drive motor 128 extends to the interior of the adaptation chamber 130. An active blade 132 is fixed to the end of the output shaft of the drive motor 128, and a passive blade 131 is arranged at a coaxial position on the side of the active blade 132.

Both ends of the inner wall of the adaptation cylinder 121 are provided with bumps for limiting the moving distance of the adaptation piston 116, so as to prevent the adaptation piston 116 from sliding out of the adaptation cylinder 121. The outer surface of the adaptation chamber 130 is sleeved with a cooling secondary fin heat sink 127. A cooling secondary fin 129 is provided in contact with the cooling secondary fin heat sink 127 and the opposite surface of the adaptation chamber 130, wherein the cooling secondary fin heat sink 127 at one end away from the adaptation chamber 130 extends to the gap between the hoisting table 126 and the top guide cover plate 119, and the cooling secondary fin heat sink 127 and the top guide cover plate 119 are not provided in contact with each other. The hoisting table 126 is suspended and fixed on the top mounting flange 124 through a plurality of hoisting rods 135 , and a sealing ring 110 is also fixed at the edge between the driving pool sealing cover 109 and the opposite surface of the top heat dissipation reflux pool 115 .
[0031] The working principle of a high-power matrix lighting fixture disclosed in the present invention is as follows: the device is installed as a whole at a desired position through the top mounting flange 124 (normally it needs to be installed vertically, and the top mounting flange 124 is installed in close contact with the ceiling). A brush is provided at the rotation connection between the intermediate transmission shaft 125 and the hanging table 126, which is used to supply power to the light-emitting matrix diode 101, so that the light-emitting matrix diode 101 emits light. The light-emitting matrix diode 101 generates a large amount of heat during operation, and the heat is transferred to the inside of the driving pool 103 through the heat-conducting copper plate 102, and then the coolant inside the driving pool 103 is heated. Therefore, when the heat generated by the light-emitting matrix diode 101 is too large (it can also be turned on all the time), the driving motor 128 is started, and the output shaft of the driving motor 128 drives the active paddle 132 to rotate, and the active paddle 132 drives the liquid inside the adaptation chamber 130 to flow, and then the flowing liquid drives the passive paddle 131 to rotate, and the passive paddle 131 drives the intermediate transmission shaft 125 to rotate, and the intermediate transmission shaft 125 drives the top thermal conductive sealing disk 108 to rotate, thereby driving the driving pool 103 and the driving centrifugal paddle 107 to rotate (the top thermal conductive sealing disk 108, the top heat dissipation reflux pool 115, the driving pool sealing cover 109, and the driving pool 103 are fixed, and the driving centrifugal paddle 107 is fixed inside the driving pool 103, so The centrifugal paddle 107 is driven to rotate as well), wherein the rotation of the centrifugal paddle 107 drives the internal coolant to rotate, so that the coolant flows toward the inner wall of the driving pool 103 under the action of centrifugal force, and then flows into the extended heat dissipation pipe 106. Since the extended heat dissipation pipe 106 rotates synchronously with the driving pool 103 (the two are fixed), the coolant inside the extended heat dissipation pipe 106 will also rotate and be subjected to centrifugal force, and then enter the top heat dissipation reflux pool 115 through the drain port 114. Since the space between the top heat dissipation reflux pool 115 and the top thermal conductive sealing disk 108 does not block the coolant, the coolant will not be driven to rotate. At this time, the coolant inside the top heat dissipation reflux pool 115 and the top thermal conductive sealing disk 108 will not be subjected to centrifugal force, and therefore will enter the driving pool 103 through the driving pool sealing cover 109 under the action of the pressure difference, and then rotate again under the action of the centrifugal paddle 107.At the same time, the shading basin 104 at the bottom of the driving pool 103 will also rotate, and the bottom blades 105 fixed on the shading basin 104 and the bottom auxiliary short blades 112 fixed on the bottom blades 105 will also rotate. The rotation of the bottom blades 105 will drive the air below to blow to the plugged heat sink 111 between the two extended heat dissipation pipes 106, thereby dissipating the extended heat dissipation pipes 106 and the plugged heat sink 111 (the temperature on the extended heat dissipation pipes 106 comes from the heat absorbed by the coolant, and then the extended heat dissipation pipes 106 transfer the temperature to the plugged heat sink 111). This part of the gas heated by the plugged heat sink 111 will flow upward, and then contact the top heat dissipation reflux pool 115 at the top (blocked by the sealing ring 110, with only one flow path). At this time, the air will flow radially outward along the top heat dissipation reflux pool 115, such as. Fig. 9 As shown, the heated air will move to the right side, and then move to the right side of the reinforcement ring 123. At this time, since the length of the bottom auxiliary short blade 112 and the bottom blade 105 exceeds the diameter of the reinforcement ring 123, during the rotation of the bottom auxiliary short blade 112 and the bottom blade 105, part of the air will be driven to flow upward from the space between the edge guide cover 117 and the reinforcement ring 123. This process will cause the air pressure between the two to decrease, and the air that is more conducive to being heated by the plugged heat sink 111 will flow from left to right (as shown in FIG. Fig. 9 as shown).
[0032] During the rotation of the top thermal conductive sealing disk 108, the top centrifugal paddle 120 and the top auxiliary short centrifugal paddle 118 fixed on the top thermal conductive sealing disk 108 will also rotate along with it. At this time, the air in the middle of the top centrifugal paddle 120 will be driven to rotate, thereby flowing outward under the action of centrifugal force. This process will cause the pressure in the middle of the top centrifugal paddle 120 to decrease, allowing the external air to enter the middle of the top centrifugal paddle 120 through the space between the top guide cover plate 119 and the lifting table 126 (air flow will be generated, allowing the air to pass through the cooling secondary plate heat sink 127). At this time, flowing air will be generated, thereby dissipating the heat of the top centrifugal paddle 120. The heat on the top centrifugal paddle 120 comes from the heat on the top thermal conductive sealing disk 108, and the top thermal conductive sealing disk 108 comes from the heat of the coolant inside the top heat dissipation reflux pool 115. At the same time, the air flowing upward from between the reinforcement ring 123 and the edge guide cover 117 will enter the top centrifugal paddle 120 and the top auxiliary short centrifugal paddle 118 and then be thrown out, thereby discharging the air with heat.
[0033] In addition, according to the use environment, it is selected whether to install the adaptation chamber 130 and its internal components. If not, the output shaft of the drive motor 128 can be directly fixed to the intermediate transmission shaft 125. For example, when the head of a person is close to the ceiling or the device in the use environment, the rotation of the device may cause the hair to be entangled, thereby causing damage to the hair. At this time, a non-rigid connection is used between the drive motor 128 and the intermediate transmission shaft 125. When the intermediate transmission shaft 125 is unable to rotate due to resistance, the drive motor 128 can drive the active paddle 132 to idle, and can also control the temperature inside the adaptation chamber 130 by energizing the secondary cooling plate 129, change the density of the liquid inside the adaptation chamber 130, and thus change the active paddle 132 to the passive The power transmission efficiency of the blade 131 controls the refrigeration secondary plate 129 to reduce the temperature of the liquid inside the adaptation chamber 130 and increase its density, so that the efficiency of the active blade 132 in pushing the passive blade 131 to rotate through the liquid is increased, thereby increasing the torque from the drive motor 128 to the intermediate transmission shaft 125, wherein the heating surface of the refrigeration secondary plate 129 is in contact with the refrigeration secondary plate heat sink 127, and the heat is dissipated when the refrigeration secondary plate 129 is working, and the external air flows through the refrigeration secondary plate heat sink 127, thereby dissipating the heat of the refrigeration secondary plate heat sink 127.
