Description

[0002] LED lighting has the advantages of long life, energy saving, power saving, low working voltage, good safety performance, etc. Using it to replace existing incandescent lamps and energy-saving lamps for high-brightness lighting is the goal pursued by industry insiders. Existing LED lighting devices use a combination of several LED lamps and use reflective devices such as reflectors to increase the height of the LED lamp. However, high-power and high-brightness LED chips will generate a lot of heat when working. The greater the chip power, the more heat it generates. If the heat is not dissipated in time, it will cause serious LED light decay or even failure. Therefore, in actual use, LED lighting usually uses a reduced power supply current due to heat dissipation limitations, and cannot use a switching power supply for power supply. In this way, the power supply power is insufficient, so that the LED lighting cannot reach the desired brightness. Therefore, the heat dissipation problem is a key factor affecting high-power LED high-brightness lighting. Summary of the invention

When the mounting plate 111 drives the heat exchange plate 110 to rotate to the side of the lamp board 106, the heat exchange plate 110 presses against the heat conductive block 117 to push the heat conductive block 117 to move, and the heat on the lamp board 106 is transferred to the heat exchange plate 110 through the heat conductive block 117 to dissipate the heat of the lamp board 106; the setting of the heat exchange block is utilized to ensure the contact effect between the heat exchange plate 110 and the lamp board 106, thereby improving the heat exchange effect between the heat exchange plate 110 and the lamp board 106, so that the heat on the lamp board 106 is quickly discharged.

[0050] A second through slot 1011 is provided on the top of the shell 101, a third through slot 1061 communicating with the heat dissipation cavity is provided on the lamp board 106, and the third through slot 1061 is located on one side of the second fan 108.

Under the guidance of the airflow in the heat dissipation cavity, the airflow outside the shell 101 enters the shell 101 through the second through groove 1011, and then flows into the heat dissipation cavity from the third through groove 1061, and the hot air in front of the lamp board 106 is discharged, thereby improving the temperature of the front of the lamp board 106 and enhancing the heat dissipation effect of the lamp board 106.

[0051] A convex rod 131 is provided on the side wall of the shell 101, and a mounting rod 104 is connected to the convex rod 131. A mounting cavity is provided on the mounting rod 104, and a second transmission shaft 118, a plurality of third transmission shafts 120 and a transmission belt 122 are provided in the mounting cavity. A plurality of second blades 119 are provided on the second transmission shaft 118, and a plurality of third blades 121 are provided on the third transmission shaft 120. The transmission belt 122 is wound around the second transmission shaft 118 and the third transmission shaft 120 so that the second transmission shaft 118 and the third transmission shaft 120 form a transmission match, the second blade 119 is located on one side of the wind guide cover 123, and the third blade 121 is located on one side of the protective plate 102. The side wall of the mounting cavity is made of a porous plate, a slider 1041 is provided on the mounting rod 104, and the convex rod 13 1 is provided with a slide groove 1311, and the mounting rod 104 is connected to the protruding rod 131 through the cooperation of the slider 1041 and the slide groove 1311; when the first fan 107 and the second fan 108 are working, the airflow enters the housing 101 from the first through hole 109 and the wind guide cover 123, and a directional airflow is formed at the entrance of the wind guide cover 123. When the airflow flows through the second fan blade 119, it drives the second transmission shaft 118 to rotate, and the second transmission shaft 118 drives the third transmission shaft 120 to rotate. The third fan blade 121 rotates to form an airflow parallel to the protection plate 102 on one side of the protection plate 102, thereby reducing the dust adhesion on the protection plate 102 and driving away the flying insects near the protection plate 102, so as to avoid a large number of flying insects approaching the lighting lamp when it is used at night.

[0052] When the lighting lamp is in use, the first fan 107 and the second fan 108 start working, and the first fan 107 and the second fan 108 introduce airflow into the heat dissipation cavity and discharge it, so that the heat in the shell 101 is quickly dissipated; when the lighting lamp is used, a heat exchange plate 110 is against the heat conductive block 117, and the heat exchange plate 110 absorbs the heat on the lamp board 106. At this time, the phase change material in the heat exchange plate 110 is in a solid phase in the upper cavity, and the partition 112 and the flap 113 are parallel. When the heat exchange plate 110 absorbs heat and transfers it to the phase change material, the phase change material absorbs heat and liquefies and falls into the lower cavity from the second through hole 1131. The phase change material is placed on the support plate 115 to squeeze the support plate 115. After receiving the phase change material, the support plate 115 moves toward the movable block 128, and the second push block 1151 is against the movable block 128 to push the movable block 128 to move, and the first push block 130 pushes the transmission ring 126 to move, and one of the transmission rings 126 moves. The ring 126 moves toward the side of the ring groove so that the transmission ring 126 contacts the second transmission wheel 127 to form a transmission match. When the second transmission wheel 127 rotates with the first transmission shaft 1071, it drives the transmission ring 126 to move. The mounting plate 111 rotates so that the heat exchange plate 110 after absorbing heat is turned away from the side of the lamp board 106. The new heat exchange plate 110 rotates to the side of the lamp board 106 and contacts the heat conductive block 117 to continue to absorb the heat of the lamp board 106. After the fitting, the second transmission wheel 127 just breaks away from the last section of the transmission ring 126, the mounting plate 111 stops rotating, and the first fan and the second fan dissipate heat for the replaced heat exchange plate 110, so that the phase change material in the heat exchange plate 110 turns back into a solid phase; when the heat exchange plate 110 rotates to a position where the upper cavity faces downward and the lower cavity faces upward, the flap 113 turns over into the upper cavity, and the phase change material in the lower cavity falls into the upper cavity through the first through groove, completing the reset of the phase change material.

[0053] The heat exchange plate 110 is automatically replaced through the state change of the phase change material after absorbing heat, so that the heat on the lamp board 106 can be quickly dissipated, extending the service life of the lamp board 106 and avoiding the situation where the heat exchange plate 110 transfers the heat to the lamp board 106 after absorbing heat, thereby greatly improving the heat dissipation effect of the lamp board 106.
