New description: [New technical field] This creation is about the structure of the lamp head, especially the LED fluorescent lamp rotating head that can adjust the LED fluorescent lamp to the appropriate illumination angle. [Prior Art] At present, the mercury fluorescent lamp on the market is widely used because its luminous efficiency is better than that of the bulb, and the utility model is widely used. The main structure of the mercury fluorescent lamp has a lamp tube, and the lamp tube has two ends. The electrode is filled with a mixed gas of low-pressure argon or argon-helium and mercury vapor, and is coated with a layer of fluorescent substance on the inner wall of the tube. When the power is turned on, current flows through the electrode, and the gas in the tube becomes plasma. The mercury vapor generates energy to excite the ultraviolet light. The fluorescent material in the lamp tube absorbs the ultraviolet light and emits visible light, which in turn causes the lamp to emit light and provide illumination for use. However, if the mercury lamp is accidentally broken, the mercury vapor in the lamp will leak out. If the toxic substance or mercury vapor is sucked into the body, it may remain inside the body and hurt. The nervous system of the human body, and the mercury and fluorescent substances contained in the mercury fluorescent lamp are not environmentally friendly, which may cause pollution problems to the environment. In order to solve the problems of the above-mentioned mercury fluorescent lamps, in recent years, lamps with light emitting diodes (LEDs) as illumination sources have been developed with great advantages, such as high brightness, power saving and long service life. The advantages are widely used in the lighting of lamps, and a UD neon lamp has been developed to replace the mercury fluorescent lamp. Since the LED fluorescent lamp does not require the use of toxic substances, it provides a more environmentally friendly fluorescent lamp.

The bottom surface of the circuit board is provided with a plurality of light-emitting diodes, and electrodes are connected at both ends of the circuit board. The long tubular lamp cover covers the light-emitting diode and the circuit board and is connected to the heat-dissipating substrate, and then the two insulating sleeves are respectively sleeved and fixed from the heat-dissipating plate and the lamp cover, and the electrodes are worn through the insulating sleeve. Since the LED is accompanied by heat generation during the process of illuminating, the accumulation of heat will increase the temperature, and the excessive temperature will cause the luminescence efficiency of the LED to decrease significantly, thereby shortening the service life of the LED. Therefore, the LED is The application must be provided with a heat dissipation structure to provide LEDs that can operate at an appropriate temperature. Therefore, the setting of the heat sink of the LED fluorescent lamp is necessary, but such a setting limits the angle of illumination, and cannot be equivalent to mercury dawn. The lamp provides 360-degree illumination, so the LED fluorescent lamp can not provide illumination in all directions' and it is inconvenient to use, and there is still room for improvement.
