When it rains or snows, and when the light is turned off for rest, the temperature inside the led line lamp will drop sharply, which will cause pressure or even greater vacuum in the lamp housing. 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, they will not be easily discharged. The water drops that cannot be drained for a long time will corrode the electronic components in the lamp body, which seriously affects the life of the led linear light .
If it is not necessary to consider the failure of the drive and power supply, one manifestation of the life span of the high-power LED line lamp is "light failure", which means that the longer it is used, the lower its brightness will be, until the life is exhausted and the lamp is off.
LED line lamps usually use aluminum as the radiator. The larger the contact area between the radiator and the air, the better. This is conducive to heat dissipation. The whole lamp works stably, and the light attenuation is small and the life is long; The bulb and ceiling spotlights should not have too large air holes to prevent mosquitoes from creeping in during use, affecting the lighting effect or causing unnecessary damage.
Glue filling problem: the silica gel under the glass surface should be thicker. If it is too thin, the solidification effect will be affected; Secondly, many people ask how to cover the glass. Because of the different strength, the amount of silica gel pressed under the glass is also different. Here, we need to compress a little; There is also a problem with waterproof vent valve. Some styles can be used. The principle of waterproof vent valve is to prevent water from entering while air can enter. This is in rainy days, when the led line lamp is rapidly cooled by rain, the waterproof vent valve can speed up the consistency of 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 air convection at ordinary times. On these points, a well done LED line lamp can easily achieve the effect of IP65 or above.
