由于和传统光源相比， LED具有寿命长、启动快、环保节能等显著优点， 所以 LED作为光源的照明装置目前被广泛应用于室内照明、室外照明、便携 式照明等照明领域， 显示出深远的发展前景。但是， 由于 LED灯是个光电器 件， 在其光电转换过程中只有 15〜25%的电能转换成光能， 其余的电能几乎都 转换成热能， 使 LED灯具的温度升高。 为了解决 LED照明灯具的散热问题， 现有技术中多采用在灯具壳体上增设裸露的散热鳍片， 这种方法有效增加 LED照明灯具的散热面积， 但同时也增加了 LED照明灯具的体积和重量， 过 小的散热鳍片间距在冷热空气交换过程中成为藏污纳垢的场所， 沉积的灰尘 导致散热能力降低并且带来触电隐患。  Compared with traditional light sources, LEDs have significant advantages such as long life, fast start-up, environmental protection and energy saving. Therefore, LEDs as light sources are widely used in indoor lighting, outdoor lighting, portable lighting and other lighting fields, showing far-reaching development. prospect. However, since the LED lamp is a photoelectric device, only 15 to 25% of the electric energy is converted into light energy during the photoelectric conversion process, and the remaining electric energy is almost converted into thermal energy, so that the temperature of the LED lamp is raised.

This method effectively increases the heat dissipation area of the LED lighting fixture, but also increases the volume of the LED lighting fixture and The weight, too small heat sink fin spacing becomes a place for dirt and dirt during the hot and cold air exchange process, and the deposited dust causes the heat dissipation capability to be lowered and the electric shock hazard.

The vertical positioning slot 12 on the 13 is fixed. Since the arc diameter of the arc-shaped limiting bracket 13 at the lower open end of the socket 7 is smaller than the diameter of the lower opening of the socket 7, a gap is formed between the respective tabs 3 on the connecting member 3. The lower air duct 11 and the fixing function of the vertical positioning slot 12 and the vertical positioning strip 13 effectively stop the connection caused by the rotation of the connecting member 3 or close the lower air duct 11; when the lamp is working, the heat inside and outside the lamp The air can freely circulate from the upper air duct and the lower air duct, effectively reducing the operating temperature of the LED chip 16 and improving the service life.
连接件 3与翅片散热器 8间形成空腔 5， 驱动电路组件 4设置在空腔 5 内。 连接件 3下开口与灯头 1扣接， 通过与螺紋式灯头、 插接式灯头等灯头 的配合， 可使这种 LED灯具适用于不同的使用环境。  A cavity 5 is formed between the connector 3 and the finned heat sink 8, and the drive circuit assembly 4 is disposed in the cavity 5. The lower opening of the connecting member 3 is fastened to the lamp cap 1, and the LED lamp can be adapted to different environments by the cooperation with the lamp cap, the plug-in lamp cap and the like.
所述灯罩外壁设有若干外凸式蜂窝状透镜， 通过透镜的折射， 消除一般 LED照明灯具灯头部位的照明盲区， 实现 360° 照明效果。 这种 LED照明灯具， 由于采用模块化的连接方式， 当出现故障时只需更 换故障部件而不必废弃整个灯具， 极大的降低了制造成本和使用成本， 同时 由于采用免螺丝的扣接方式， 方便了安装和维修工作。  The outer wall of the lampshade is provided with a plurality of convex honeycomb lenses. Through the refraction of the lens, the illumination blind zone of the lamp head portion of the general LED lighting fixture is eliminated, and the 360° illumination effect is realized. Due to the modular connection method, the LED lighting fixture only needs to replace the faulty component in the event of a failure without having to discard the entire luminaire, which greatly reduces the manufacturing cost and the use cost, and at the same time, due to the screw-free fastening method, Convenient for installation and maintenance work.
