Technical Field

The utility model relates to a car light specifically, relates to a sectional type reflector panel for car light. The utility model discloses still relate to a car light system and a vehicle.

Background

The existing car light is mostly formed by adopting a light blocking way of a light blocking plate, namely, the light blocking plate processed into a specific shape is adopted to block one side of a car light source, and the light of the unblocked part of the light source is converged by a lens and irradiates the road surface to form a specific light shape. Since the light barrier has been previously processed into a specific shape, the light barrier structure can only form a specific light shape.

There is also a vehicle lamp structure in which a light shape is formed by reflecting light emitted from a light source of a vehicle lamp onto a road surface by a reflector, and in the vehicle lamp structure, the shape of the light shape depends on the shape of the reflector. The existing light reflecting plates are all of an integral structure, and the shapes of the light reflecting plates are all of specific shapes which are processed in advance, so that the light shapes formed by reflection of the light reflecting plates are also fixed, and the light shapes cannot be adjusted.

In recent years, with the advent of adaptive high beam illumination modes, more diverse requirements are being placed on the light shapes of vehicle lamps. Matrix type LED headlamp technology has also emerged accordingly. This matrix type LED headlight divides into a plurality of different blocks with the illumination space of whole head-light, and every block is responsible for the illumination by an LED, and the LED through different blocks is lighted and is extinguished and produce different light types. Wherein each particular block of LEDs may provide a minimum of about 1 deg. illumination area. Thus, by specifically controlling one or more LEDs of the matrix LED headlight, the resulting light distribution can be finely varied, resulting in a multiplicity of illumination light patterns. And can be used to implement a localized high beam function or a marker beam function.

The existing matrix type LED headlamp has the following defects:

1. a plurality of LED chips are arranged, and light shape change is realized by combining on and off of a light source. The more the number of light sources, the more the state of light shape change. However, the excessive number of light sources leads to electronic control and complicated circuit, which fundamentally leads to waste of light sources and increase of cost.

2. Because the LED chip necessarily occupies a certain light-emitting area, the LED chip is generally not less than 0.5mm²In addition, the light source distribution area is large due to the distance between the light emitting chips, which makes the design of the imaging system difficult, so in the prior art, the light of the multi-light emitting chip is modulated once through the primary light distribution unit, and then is projected to the road surface through the secondary light distribution unit (or called as projection optical device), which is generally a collimating lens, to form the expected light shape. However, the number of LED chips is large, and the structure of the primary and secondary light distribution units is complicated, which results in a large volume and heavy weight of the matrix LED headlamp.
