Light guiding lens and vehicle lamp

Abstract

A light guiding lens and a vehicle lamp are shown. Under the conditions that the illumination is not deteriorated and the cost is not increased, the light guiding lens can give off more light. The light guiding lens (2) guides light from a plurality of LEDs (3) and gives off light. The light guiding lens (2) comprises a first extension part (21) and a second extension part (22), which are connected to each other; and a flange part (210) extending from the first extension part (21). The flange part (210) comprises a plurality of light incident parts (211) to introduce the light from the plurality of LEDs (3). The plurality of the light incident parts (211) and the extension direction (E) of the first extension part (21) are intersected and form an acute angle. In the intersection direction (X), the plurality of the light incident parts (211) are arranged in different positions and guides the light from corresponding LEDs in the flange part (210) along the light guiding direction (Y) facing the first extension part (21). The light guiding direction (Y) is perpendicular to the intersection direction (X), faces the second extension part (22), and intersects the extension directions (E) to form an acute angle. The first extension part (21) has a plurality of second reflectors (216), which can make light from the flange part (210) carry out internal reflection in the second extension part (22).

Description

technical field [0001] The present invention relates to a long substantially rod-shaped light guide lens and a vehicle lamp including the same. Background technique [0002] Conventionally, as a vehicle lamp mounted on a vehicle, a vehicle lamp that emits light from a long rod-shaped light guide lens (so-called light guide rod) is known. In such vehicle lamps, light sources such as LEDs (Light Emitting Diodes) are generally opposed to longitudinal end surfaces of the light guide lens, and the light guide lens is made to emit light by light entering the light guide lens from the end surfaces. [0003] However, in such vehicle lamps, the light incident surface of the light guide lens is basically limited to the end surfaces on both sides. Therefore, when simply making the light guide lens emit light brighter, it is necessary to replace it with a high-output LED. Or for this purpose, a heat sink or the like is added, resulting in high cost. [0004] Therefore, in the vehicula...
