High Quality Street Light Housing Factory Introduces The Quality Related Knowledge Of Street Lamp Housing
There are more and more manufacturers of LED street lamp housings, and the quality of their products has become uneven. So, how to distinguish the quality of LED street lamp housings? Let’s learn about it with High Quality Street Light Housing Factory.
1. Carefully check whether there are cracks, peeling, corrosion and bubbles on the surface of the LED street lamp housing. If these phenomena appear, it means that it is unqualified. The surface of a good LED street lamp housing is smooth and clean.
2. The LED street lamp shell is anodized, but during the anodizing process, the surface of the LED street lamp shell has many small holes. The existence of small holes will affect the oxidation resistance and corrosion of the oxide film, so it is necessary to treat such small holes Seal the hole. The commonly used methods for quality inspection of sealing include acid leaching, admittance and phosphobutyric acid. The acid leaching method is generally used in the on-site inspection. That is, the surface of the LED street lamp housing is wiped clean with acetone to remove oil and dust, and 50% nitric acid by volume is dropped on the surface and gently scrubbed. After 1 minute, the nitric acid is washed off with water, and then wiped dry. Drop a drop of medical purple medicine onto the surface. After 1 minute, wipe off the purple medicine and clean the surface thoroughly, carefully observe the traces left. The poorly sealed LED street lamp housing will leave obvious marks, and the heavier the marks, the worse the sealing quality.
3. An important factor affecting the service life of LED street lamp housing is corrosion resistance. Corrosion resistance inspection includes copper accelerated acetic acid salt spray test and alkali drip test. Here is an introduction to the drop alkali test: the corrosion resistance of the LED street lamp housing is to drop about 10mg, 100g/L NaOH solution on the surface of the LED street lamp housing at 35℃±1℃, and visually observe the droplet until corrosion bubbling occurs. Calculate the penetration time of the oxide film.
4. Check whether the LED street lamp housing and its packaging are marked with the product standard code and production license number, etc.: There is an oxide film on the surface of the LED street lamp housing, which is formed by anodic oxidation, which has strong anti-oxidation and Corrosive, can effectively guarantee the service life of the LED street lamp housing.
The above is the introduction of Platinum Lamps to distinguish the quality of LED street lamp housings. LEDs are known as the green lighting source with prospects for development in the 21st century due to the advantages of high brightness, low heat, short-lived, non-toxic, recyclable and reusable.
Through the above introduction, Led Street Light Housing Manufacturers hopes that you can simply refer to the content of this article in future use.
