Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a light-emitting diode lighting fluorescent lamp. Background technique [0002] LED is the abbreviation of English light emitting diode (light emitting diode). LED is a semiconductor that can convert electrical energy into visible light. With many advantages such as long life, high luminous efficiency, no radiation, and low power consumption, LEDs are gradually introduced into lighting fixtures as light sources with the introduction of energy-saving and green lighting concepts. [0003] At present, incandescent bulbs or fluorescent fluorescent lamps are basically used as light sources for daily lighting such as daily bulbs and fluorescent lamps. However, the electro-optical conversion efficiency of incandescent bulbs and fluorescent fluorescent lamps is relatively low, and their heat is high Short, generally only about 3000 hours. [0004] The LED can overcome the ab...

Problems solved by technology

[0010] Among them, LED fluorescent lamps are more widely used than LED bulbs, especially in homes or offices. The power supply of existing LED fluorescent lamps is generally fixed together with the aluminum substrate and placed inside the tube body, making the originally narrow space in the tube body more crowded. , which directly leads to poor heat dissipation of the LED. According to relevant information, the normal operating temperature of the LED is 50°C. If the temperature exceeds 55°C, the life of the LED will be reduced by half, so this structure is very unreasonable.

[0011] In addition, the aluminum substrate of many LED fluorescent lamps is placed in the groove of the inner wall of the radiator. Since the aluminum substrate is the cavity of the radiator, the heat generated by the LED cannot be effectively transmitted to the radiator, and the heat dissipation effect is greatly reduced. If the internal temperature is too high, it will also affect the life of the LED; there are also some fluorescent lamp radiators whose bottom is flat, and then put the aluminum substrate directly on the plane of the radiator. After the device is made solid, the weight is greatly increased. The fluorescent lamp generally needs to be hung on the roof, and the weight requirement is also very important. personal injury
