Study on Material Selection of Bicycle Headlight Lamp Housing

With the rapid advancement of energy-saving light emitting diode (LED) lamps, LEDs have replaced traditional light sources with filaments known for their high energy consumption. LEDs also allow the persistent issue of providing a continuous and stable power supply for bicycles to be resolved. We delved into the characteristics of six commonly used materials for crafting car lamp housings and explored the advantages and disadvantages of the use of the materials in the production of car lamp housings. To circumvent the expenses associated with the distribution design and manufacturing of light sources, we employed low-cost general-purpose household LED lamps as the light source in designing the headlight of the bicycle. We conducted a series of experiments to assess the lamps' impact resistance, weather resistance, heat resistance, chemical resistance, and overall durability. Additionally, we measured the specific gravity of the six materials and tested their respective heat distortion temperatures. Finally, market research was performed to ascertain prevailing prices and formulate production recommendations that take into account cost considerations.
