Description

車輛警示燈vehicle warning light

本發明係有關於一種車輛警示燈。 The invention relates to a vehicle warning light.

按，隨著科技的進步，近年來在造車工藝上亦跟著不斷進化，而車輛用的燈具也持續地在推陳出新，如車用大燈為了提升聚光性及亮度，無論是鹵素燈或是LED燈都採用了魚眼結構。其中車輛用的警示燈(如煞車燈，方向燈、後照鏡燈等)為了增加視覺上的圖案辨識度，會在燈罩上設有不導光之部位及導光部位，以使警示燈發光時呈現出圖案。然而，如此會因光線照射到不導光之部位而浪費掉，且導光部位之亮度會過大而造成用路人刺眼，存在亟待改善之缺弊。 Press, with the advancement of technology, the car manufacturing process has also continued to evolve in recent years, and vehicle lamps have also continued to be introduced. For example, in order to improve the focus and brightness of car headlights, whether they are halogen lamps or LED lights all adopt a fisheye structure. Among them, warning lights for vehicles (such as brake lights, direction lights, rear mirror lights, etc.), in order to increase visual pattern recognition, will be equipped with non-light-guiding parts and light-guiding parts on the lampshade to make the warning lights shine. Patterns appear. However, in this way, the light will be wasted when it shines on the parts that do not guide the light, and the brightness of the light guide part will be too high, causing dazzling to passers-by. There are shortcomings that need to be improved urgently.

因此，有必要提供一種新穎且具有進步性之車輛警示燈，以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive vehicle warning light to solve the above problems.
