Stanley Electric has been granted a patent for a vehicle lamp that includes multiple light source modules with different colored light emitting elements and lens bodies. The modules are arranged in a matrix pattern to create a light emitting area. Each module consists of five light emitting diodes (LEDs) – two red, two green, and one blue – arranged in a cross shape, with the central position occupied by one LED and the others placed in different positions around it. The patent aims to improve the design and functionality of vehicle lamps. GlobalData’s report on Stanley Electric gives a 360-degree view of the company including its patenting strategy.

A vehicle lamp with multiple colored light sources
A recently granted patent (Publication Number: US11686450B2) describes a vehicle lamp with unique features. The lamp consists of multiple light source modules, each containing five light emitting diodes (LEDs) - two red, two green, and one blue. These modules are arranged in a matrix pattern to create a light emitting area. The LEDs in each module are positioned in a cross shape, with one LED at the center and the others placed above, below, left, and right of the center LED. The red LEDs can be located at the center or the side positions, while the green LEDs can be at the center or the side positions. The blue LED is positioned at one of the side positions.
The lens body in front of the light source modules has its optical axis center located between the positions of the red LEDs. This arrangement ensures optimal light distribution. The light source modules are mounted on the same board, and the lens bodies form a lens array.
The vehicle lamp also includes a lighting controller that can control the LEDs in each module. This controller enables the lamp to display various functions, such as a tail lamp emitting red light, a brake lamp emitting red light, a turn lamp emitting orange light, or a back lamp emitting white light. Additionally, the lighting controller can even display images in the light emitting area.
This patented vehicle lamp design offers a unique configuration of light source modules and lens bodies, resulting in efficient light distribution. The ability to control the lighting of individual LEDs allows for versatile functionality, including displaying different types of lamps and even images. This innovation could potentially enhance the safety and aesthetics of vehicle lighting systems.
