Description

vehicle warning light

The invention relates to a vehicle warning light.

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.

Therefore, it is necessary to provide a novel and progressive vehicle warning light to solve the above problems.

The main purpose of the present invention is to provide a vehicle warning light that can effectively present a pattern effect and avoid light waste. In addition, it can prevent the light from being too dazzling to improve practicality.

In order to achieve the above object, the present invention provides a vehicle warning light, which includes a lamp holder, a light-emitting module and a light guide lamp cover. The lamp holder is provided with a receiving groove, and the receiving groove is opened along an axial direction. The light-emitting module is arranged in the container, and the light-emitting module is provided with at least one light-emitting element. The light guide lampshade includes an opposite first side and a second side. The first side faces away from the light-emitting module, and the second side faces the light-emitting module. A ridge is protruding from the second side. The mirror is between the at least one light-emitting element and the first side. The light emitted by the at least one light-emitting element is refracted by the lens and then emitted to the first side. The first side is provided with a first soft light portion. The projection area of the first soft light portion along the axial direction covers the light-emitting module. The second side is provided with at least one inclined portion and at least one planar portion. The at least one planar portion is perpendicular to the axial direction. Each inclined portion A second soft light part is provided. Viewed along the axial direction, each second soft light part is located outside the projection surface of the first soft light part along the axial direction; wherein, when the light-emitting module emits light, The light will be emitted to the first soft light part, part of the light is refracted by the first soft light part and emitted from the first side, and the other part of the light is reflected from the first soft light part to the third of the at least one inclined surface. The two soft light parts are then reflected and refracted toward the first side. Therefore, when viewed from the first side, the first soft light part located on the first side and the first soft light part located on the second side can be observed at the same time. The shapes of at least one inclined portion and the second soft light portion together form a special pattern.
