LED line lamp, namely led wall washing lamp series aluminum profile lamp body, is compact and lightweight. The end cover and mounting bracket are made of aluminum alloy high pressure die casting high temperature resistant silicone rubber sealing ring to ensure the reliability of waterproof. Lamps can be installed in single or multiple combinations. Suitable for all kinds of buildings, indoor and outdoor local or contour lighting.
In the case of rain or snow, and when the lights are turned off for rest, the temperature inside the LED line lamp will drop sharply, and the sharp drop in temperature will lead to instantaneous pressure or even greater vacuum inside the lamp shell. At this time, air or moisture will sneak into the lamp body through the seal gap and condense into water droplets. Once the sealed lamp body produces water droplets, it is not easy to be discharged. The water droplets that cannot be discharged for a long time will corrode the electronic components in the lamp body, which will seriously affect the life of LED line lamp.
If you don’t need to consider the failure of the drive and power supply, a performance of the high-power LED line lamp’s life is “light failure”, which means that the longer it is used, the lower its brightness will be until its life is exhausted.
LED line lamps usually use aluminum as radiator. The larger the contact area between radiator and air is, the better. This is conducive to heat dissipation. The whole lamp works stably with small light attenuation and long service life. Bulb and ceiling spotlights should not have too large air holes, so as to avoid mosquitoes crawling into the lamp, affecting the lighting effect or causing unnecessary damage.
For the problem of pouring glue, the silica gel under the glass surface should be thicker. If it is too thin, it will affect the solidification effect. Secondly, many people ask how to cover the glass. Because of the different strength, the amount of silica gel under the glass is also different. What we need here is to compress it a bit; There is also the problem of waterproof ventilation valve. Some high-grade models will be used. The principle of waterproof and breathable valve is to prevent water from entering and air can enter. In rainy days, when the rain drops rapidly, the waterproof and breathable valve can accelerate the temperature inside and outside the lamp body to make the temperature inside and outside of the lamp body consistent, so that the pressure change will not be too violent, so as to avoid damaging the internal components of the lamp body, which is also conducive to heat dissipation To accelerate air convection. On these points, a good LED line lamp can easily achieve the effect of IP65.
The light color of high-quality LED line lamp must be the same, there will be no yellow light or other light color. If you don’t know how to distinguish, you can teach you a small method. You can get the answer you want only by lighting these lights and observing their light color changes. Due to the high brightness of LED line lamp, it is difficult to judge the brightness of two kinds of lamps of the same type under the same conditions by using the method of direct vision, and it is also easy to damage the eyesight. Generally, we suggest to cover the light source with a piece of white paper, and then compare it after the attenuation of light by white paper. In this way, it is easier to see the difference of light brightness. The higher the brightness, the better.
