What is a lighting part? except the light source, it includes all the components used for fixing and protecting the lighting source, as well as the necessary circuit connected to the power supply.
Modern lamps includes household lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, special lighting, etc. From the birth of electricity, incandescent bulbs appeared as the earliest home lighting, later improved to the fluorescent tube, then to energy-saving lamps, halogen lamps, halogen tungsten lamp, special material gas discharge lamp, till LED lighting, the lighting lamps and lanterns, most of them developed under the development of light sources, such as from the light to fluorescent stents to all kinds of craft lighting, etc.
As an Aluminum Die Casting manufacturer, the lamp housing is a important business in our factory.
