DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a new technical solution: a floodlight, comprising a floodlight body 1, a light module protection shell 8 is fixedly installed on the rear surface of the floodlight body 1, a light module 2 is arranged in the light module protection shell 8, and slide grooves 3 are respectively opened on both sides of the floodlight body 1;

[0025] A heat dissipation mechanism, which is arranged on the rear surface of the light emitting module protective shell 8, and is used for heat dissipation of the light emitting module 2. The heat dissipation mechanism includes heat dissipation fins 9, and the heat dissipation fins 9 are respectively fixedly mounted on both sides of the light emitting module protective shell 8;

[0026] The supporting mechanism is arranged on the floodlight body 1 and is used to support the floodlight body 1 . The supporting mechanism comprises two first fixing rods 4 , and the two first fixing rods 4 are slidably sleeved in the inner walls of the two sliding grooves 3 .

[0027] Furthermore, the heat dissipation mechanism also includes a semiconductor cooling sheet 11 , and the semiconductor cooling sheet 11 is arranged in the inner wall of the heat dissipation back plate 10 .

[0028] Furthermore, the heat dissipation mechanism further includes a cooling fin 12 and a cooling fan 13 . The cooling fin 12 is fixedly mounted on the front surface of the semiconductor cooling fin 11 , and the cooling fan 13 is fixedly mounted on the front surface of the cooling fin 12 .

[0029] Furthermore, the heat dissipation mechanism also includes a heat dissipation fan 14 , which is fixedly mounted on the rear surface of the semiconductor cooling plate 11 .

[0030] Furthermore, the supporting mechanism also includes two supporting rods 5 , which are rotatably sleeved on the outer surface of the first fixed rod 4 .

[0031] Furthermore, the supporting mechanism also includes two second fixed rods 6 and an n-shaped handle 7. The two second fixed rods 6 are rotatably sleeved on the inner surfaces of the two support rods 5. The handle 7 is fixedly installed at the opposite ends of the two second fixed rods 6, and the n-shaped handle 7 is rotatably connected to the outer surface of the floodlight body 1. When the floodlight is in use, the light-emitting module 2 on the floodlight body 1 will generate heat when used for a long time, and the heat will fill the entire light-emitting module protective shell 8. At this time, the heat dissipation fins 9 fixedly installed on both sides of the light-emitting module protective shell 8 will absorb the heat in the light-emitting module protective shell 8 and exchange heat with the air for cooling. The semiconductor refrigeration sheet 11 can be connected to an external power supply. At this time, the semiconductor refrigeration sheet 11 starts to operate for cooling. The cold air produced by the semiconductor refrigeration sheet 11 is transmitted through the cooling sheet 12, and the cold air is transferred to the light-emitting module protective shell 8 through the cooling fan 13, so that the light-emitting module 2 inside is cooled. When the semiconductor refrigeration sheet 11 is in operation, the heat generated by itself will be discharged through the cooling fan 14, making it difficult for it to heat up. The cooling is interfered by rotating the n-shaped handle 7, which drives the two second fixed rods 6 fixedly installed on the inner wall to move downward. While the two second fixed rods 6 move downward, a downward pulling force is applied to the two support rods 5 which are rotated on the outer surface, so that they are gradually tilted. At the same time, the two support rods 5 pull the first fixed rod 4 rotating on the inner surface to slide downward in the inner wall of the slide groove 3 until the two support rods 5 are tilted to effectively support the floodlight body 1. The floodlight can accelerate the adsorption of heat from the light-emitting module protective shell 8 through the heat dissipation fins 9, and the air contact area is increased to better perform heat exchange and cooling treatment, while the semiconductor refrigeration sheet 11 can actively cool the light-emitting module 2, and by transmitting the produced cold air, it can quickly cool the light-emitting module 2 to increase its service life. When placing the floodlight, the n-shaped handle 7 can be rotated, and the n-shaped handle 7 drives the two support rods 5 to be tilted. At this time, the floodlight body 1 is supported by the two support rods 5, so that it can be placed stably for lighting, which is more convenient.

[0032] Working principle: When the floodlight is used, the light-emitting module 2 on the floodlight body 1 will generate heat after long-term use, and the heat will fill the entire light-emitting module protective shell 8. At this time, the heat dissipation fins 9 fixedly installed on both sides of the light-emitting module protective shell 8 will absorb the heat in the light-emitting module protective shell 8 and exchange heat with the air to cool it down. The semiconductor refrigeration sheet 11 can be connected to an external power supply. At this time, the semiconductor refrigeration sheet 11 starts to operate for cooling. The cold air produced by the semiconductor refrigeration sheet 11 is transmitted through the cooling sheet 12, and the cold air is transferred to the light-emitting module protective shell 8 through the cooling fan 13, thereby cooling the interior of the light-emitting module. The light emitting module 2 is cooled, and the heat generated by the semiconductor refrigeration sheet 11 during operation will be discharged through the cooling fan 14, making it difficult for the semiconductor refrigeration sheet 11 to generate heat and interfere with the cooling. By rotating the n-shaped handle 7, the n-shaped handle 7 drives the two second fixed rods 6 fixedly installed on the inner wall to move downward. While the two second fixed rods 6 move downward, a downward pulling force is applied to the two support rods 5 rotating on the outer surface, so that they are gradually inclined. At the same time, the two support rods 5 pull the first fixed rod 4 rotating on the inner surface to slide downward in the inner wall of the slide groove 3 until the two support rods 5 are inclined to effectively support the floodlight body 1.
