Description

Blind area lamp

Technical Field

The utility model relates to a blind area lamp.

Background

Automotive rearview mirrors are required to provide some visual information to the driver while not interfering with the driver or passengers or people in other vehicles traveling nearby. Some examples of existing automotive rearview mirrors and optical assemblies for illuminating illuminated features are shown in U.S. patent No. US 8,708,536, which is incorporated herein by reference for all purposes. It is desirable that the optical package used in the rearview mirror be as light and small as possible, and use as few LEDs or light sources as necessary. To reduce the number of light sources used, light from the light sources in the optic package is reflected and directed by one or more reflectors in the optic package to direct light through the aperture to illuminate the illuminated feature or manage the light if desired. The reflectors used in the optical assembly may be angled, flat, stepped, curved, or otherwise shaped to direct and orient the light emitted from the light source. These angles, planes, curves or other shapes that form the reflective surface topography are referred to by the inventors as "facets".

As automobile designers and manufacturers continue to demand smaller and thinner optical assemblies, there is a need for better light reflection control in optical assemblies used with rear view mirrors and other mirror assemblies. Small, thin reflectors are desirable because they provide lighter weight and a smaller form factor, thereby reducing the overall size and weight of the automotive mirror. For thin reflectors with shallow facets (light facets), it becomes more difficult to control the light in the optical assembly, and thus the amount of "stray light", i.e. light emitted in undesired or undesirable directions. Manufacturers also require increasingly efficient methods to manufacture complex and compact optical assemblies to meet the specifications of automotive designers and manufacturers.

By using selective reflection in the optical assembly in an automotive rearview mirror, the light control difficulties inherent in thin reflectors can be reduced. This enables more light control to be built directly into the reflector, so that no additional light control elements (e.g. light control shutters) are required to control stray light. A mask is used in the selective metallization process to cover the portions of the reflector that should not be metallized and to allow the portions of the reflector that should be metallized to be metallized, thereby applying selective reflection to the reflector.

The product designed according to the patent still has the phenomenon of uneven light emission, but the reason is that the product depends on the reflection of peripheral small planes too much, so that the edge brightness of the product is larger, the center brightness is weaker, and even if three LEDs are used, the condition also exists.
