In the present invention, since the heat dissipation plate is installed between the lower casing and the upper casing, the heat dissipation hole is disposed on the heat dissipation plate, and the air outlet of the ventilation groove is directly opposite to the heat dissipation hole. When the LED thread is used for the heat dissipation system of the spotlight, the LED light source is operated. Most of the heat generated is transmitted to the heat sink. Under the action of the fan, the outside wind enters the cavity, and heat is exchanged in the heat sink. The hot air is dissipated from the heat dissipation hole, and the generated wind flow is formed in the casing. On the side, the light is emitted from the lamp housing, and the two do not affect each other. Therefore, the airflow generated during heat dissipation does not affect the quality of the spot. In addition, since the windshield is provided, regardless of how the LED light source changes position, under the action of the light blocking plate, the LED light source can be prevented from seeing through the heat dissipation hole, thereby improving the utilization of light.
本发明的散热方法是: LED螺紋聚光灯散热系统工作时, LED光源 7 产生热量, 并将热量传递到散热器 8中, 同时风扇 9工作, 在腔体内形成 负压, 外界的冷风经散热板 11位于风扇后方的散热孔、 间隙进入到散热器 8 内, 冷风在散热器 8 中进行热交换变成热风; 在风扇的作用下, 热风经 间隙、 散热板位于风扇前方的散热孔散出。 当需要调节光斑时, 通过马达 带动 LED光源 7发生位移, 此时, 由于挡光板的作用, 那么, 不管 LED 光源 7在哪一位置, LED光源 7的光都不会从散热孔中透出, 从而提高了 光的利用率。  The heat dissipation method of the present invention is: when the LED threaded spotlight heat dissipation system is working, the LED light source 7 generates heat, and transfers the heat to the heat sink 8, while the fan 9 operates to form a negative pressure in the cavity, and the outside cold air passes through the heat dissipation plate 11 The vents and gaps at the rear of the fan enter the heat sink 8. The cold air exchanges heat in the heat sink 8 to become hot air. Under the action of the fan, the hot air passes through the gap, and the heat sink is scattered in the heat vent hole in front of the fan. When the spot needs to be adjusted, the LED light source 7 is displaced by the motor. At this time, due to the action of the light blocking plate, no matter which position the LED light source 7 is, the light of the LED light source 7 does not pass through the heat dissipation hole. Thereby increasing the utilization of light.
在本发明中, "前"是指灯头壳体一端, "后"是指端盖一端, "上"指 图 3中的上方。  In the present invention, "front" refers to one end of the cap housing, "rear" refers to one end of the end cap, and "upper" refers to the upper side in FIG.
