LED street light shell production process
LED lamp manufacturers: What is the production process of LED street lamp shells? The basic steps of the production process of our LED street lamp shell are as follows: 1. Mold manufacturing 2. Rough pressing 3. Finishing and surface treatment 4. Surface phosphating treatment 5. Powder coating 6. High temperature curing.
LED street light shell production process
LED street light housings are designed by manufacturers and generally have relevant patents. Other manufacturers are not allowed to produce the same or similar housings without permission. The street lamp manufacturer asks the mold factory to make the lamp shell mold, and then it is integrally die-casted with aluminum alloy to produce the blank. Why use aluminum alloy? Aluminum alloy is the most widely used non-ferrous metal material in the industry. Aluminum alloy has low density, high strength and good plasticity. It can be processed into various profiles and has good electrical conductivity, thermal conductivity and corrosion resistance. After the aluminum alloy is integrally die-casted, finishing and surface treatment, phosphating, powder spraying, and finally high-temperature curing are required. Why Surface Treatment? The aluminum alloy of the untreated street lamp housing has limited corrosion resistance and needs to be phosphating and powder spraying.
LED street light shell production process
Why use LED street light housings? The street light source is small, and its heat dissipation capacity is limited. After installing the LED street light lamp housing, the contact area with the air is enlarged, the heat dissipation effect is effectively improved, and the life of the whole lamp is improved, and the photoaging time of the LED light source is effectively slowed down. The quality of the LED street lamp shell is good, which can effectively improve the service life of the whole LED street lamp.
