Talking about several components of LED street lamp design

Shell: The shell is aluminum alloy. The biggest feature of aluminum alloy is that it will not rust. This is the only necessary requirement for LED street lights installed in the open air. The manufacturing of the shell mainly considers the appearance and heat dissipation. The heat dissipation is designed first, and then the shape is designed.

Aluminum substrate: Aluminum substrate is the key to the entire heat dissipation technology. Now many manufacturers have formed an integrated LED street lamp head, and some of the materials used in the housing can also dissipate heat in one step. The aluminum substrate should also consider not to accumulate water and dust, and should make a pit to let it flow down. There are many designs, mainly based on personal creativity.

Lamp beads: LED street lamps generally use high-power LED street lamps. High-power LED street lamps refer to a single lamp bead above 1W. Nowadays, the more popular ones are mainly in the following forms, distributed, modular and integrated.

Power supply: With the maturity of LED technology, the development of power supply has also rapidly improved. Many newly opened manufacturers have at least a 5-year warranty, and some have a 3-year warranty. The power supply is generally electronic components, which play the role of the engine in the LED street lamp. For example, the constant current power supply will reduce the strobe, easy to start, save electricity and ensure the life of the LED lamp.
