What are the factors that affect the service life of LED line lamps? Many customers often worry that the service life of LED line lamps is not long. In the face of the sun and rain, the brightness of LED line lamps will be weaker than when they first bought them. In order to answer some of the above questions, let's discuss it with them below.
As for the waterproof vent valve, some high-end models will be used. The principle of the waterproof vent valve is to prevent water from entering and air can enter. In rainy days, when the LED line lamp cools rapidly in the rain, the waterproof vent valve can accelerate the consistency of the temperature inside and outside the lamp body, so that the pressure change will not be too violent, so as to avoid damaging the internal components of the lamp body. It is also conducive to heat dissipation and accelerate air convection at ordinary times. On these points, a well made LED line lamp can easily achieve the effect of above IP65.
In the use of outdoor environment, the daily sun, wind and rain are the inevitable factors causing the brightness decline of LED line lamps. In addition to these unavoidable conditions, there are also human factors. Generally, the service life of LED is about 50000 hours, which is understood by ordinary people's thinking. The total service life of 50000 hours is 50000 hours. If the light is turned on at 6 p.m. until 12 a.m., the light is only turned on for 6 hours a day, 365 days a year and 2190 hours a year, it can't be used for 23 years.
With the accumulation of service time and the erosion of sun and rain, the LED line lamp will not be as bright as before after a certain period of time. There is a professional word in the lighting industry - light decay. The physical phenomenon of light decay is an unavoidable problem for LED lamps. Just like life, life and death, lamps also have service life.
Generally speaking, the surface cover of LED line lamp can be replaced according to the structure. Take a 30 * 45 glass inserted LED line lamp for example. Since it can be inserted with glass, it can also be replaced with a milky white acrylic surface cover with similar thickness. Can all LED line lamps be replaced in this way? No, it needs to be judged according to its structure.
In case of rain or snow and when the light is turned off for rest, the temperature in the LED line lamp will drop sharply, which will lead to instantaneous pressure or even greater vacuum in the lamp shell. At this time, air or moisture will sneak into the lamp body through the sealing gap and condense into water droplets. Once water droplets are generated in the sealed lamp body, it is not easy to be discharged. Water droplets that cannot be discharged for a long time will corrode electronic components in the lamp body and seriously affect the service life of LED line lamp.
