[0002] The special atmosphere lamp hard light bar is an innovative light source design for in-vehicle or indoor atmosphere lighting, which combines the characteristics of "special shape" (irregular shape) and "hard light bar" (hard light bar material), and is commonly used in automotive interiors, home lighting and other decorative applications. The light bar is a lighting device that uses light guiding principles, usually made of transparent or translucent materials. When the light source enters through one end of the light bar, the light will propagate through total reflection within the bar-shaped body until it is emitted from the other end or side of the bar. An important feature of the light bar is that the light is uniform and soft, which can avoid local over-brightness or over-darkness. The hard light bar is more solid in material than the soft light bar and can withstand higher pressure and external force, making it suitable for long-term use. During the processing of the special atmosphere lamp hard light bar, the light bar needs to be pressed into the atmosphere lamp bracket.
