Led filament bulb is a new type of energy-saving lamp, which can replace the traditional incandescent lamp. Traditional light bulbs have high energy consumption and short life. The appearance of the LED filament bulb produced by the outdoor string lights manufacturer adopts the traditional lamp shape, and the internal light source adopts LED lamp beads. It has the advantages of energy-saving, environmental protection, long life, no flash, environmental protection, and other advantages. In view of the scarcity of global resources and the increased awareness of environmental protection, the use of LED lights is increasing.
LED filament bulbs for ordinary incandescent lamps used for lighting, need to be filled with about 0.1 MPa of argon nitrogen mixed gas. In order to better suppress the evaporation of the tungsten wire and reduce the heat loss of the gas, k gas and xenon gas are more effective. However, these two inert gases are much more expensive than argon. Therefore, people strive to develop small bulbs with low gas consumption. Incandescent lamps use tempered glass or quartz glass to make the bulb, which reduces the size of the bulb and can make the air pressure higher. Due to the high air pressure, the effect of suppressing the evaporation of the filament is better, so the working temperature of the filament can be increased, and the luminous efficiency of the lamp can be increased accordingly (about 30% to 40%), and the service life is 3-4 times the original.
The energy consumption of led lamps is only one-tenth of incandescent lamps and one-quarter of energy-saving lamps. The life span of led lights can exceed 100,000 hours. The led lamp is also environmentally friendly, does not contain mercury and other harmful substances, and will not cause damage to the environment. The led lamp does not contain infrared and ultraviolet rays during use, so it will not attract insects.
There is a certain inclination between the interface of the high-quality LED lamp and the spiral connector, which is very practical for installation and can prevent the installer from getting an electric shock. Our company provides patio suspended string light.
Requirements for bubble shell
Look at the bubble shell of the bulb. The so-called bubble shell refers to the front transparent glass shell. In incandescent lamps, they are all made of glass. However, in LED bulbs, although glass can also be used as a bulb, this is rarely done. Because LED bulbs are five times heavier than incandescent bulbs, if they are made of glass, they will fall to the ground and are likely to break. Therefore, more LED bulbs use plastic as the bulb to prevent damage.
Generally, the requirements for the bubble shell are as follows: 1. High light transmission, high diffusion, no glare, no light shadow; 2. The concealment of the light source is better (LED lamp beads can not be seen as much as possible); 3. The light transmittance is as high as 90% Above; 4. High flame resistance; 5. High impact strength.
