LED lighting is not a mechanical part. LED lighting is an electronic product that uses the luminous properties of semiconductor materials to generate light, with the advantages of high efficiency and energy saving, long life and environmental protection. It is composed of LED chip, conductive plate, radiator, shell, etc., of which LED chip is the core component. Although the LED lighting contains a certain amount of metal and plastic materials, it mainly relies on electricity to drive the LED chip light, does not involve mechanical transmission and moving parts, so it cannot be classified as mechanical parts.
