LEDs combine design flexibility with rugged, practical circuitry that enables automotive designers to design eye-catching and long-life and high-performance headlights. Automotive designers are increasingly using LEDs in lighting systems because LEDs can be used to create unique, eye-catching designs that can help distinguish between new and older models, or differentiate between high-end and economical models. There is no doubt that the era of automotive LED lighting has arrived, but it has not yet reached its full potential. Future models will use more LED lights, LED lights will have new shapes and colors, and control of individual LEDs will be enhanced. A simple LED string will be placed in the LED matrix, and each LED in the matrix can be individually dimmed by computer control, enabling unlimited vivid illumination patterns in real time. This future is close at hand: Linear Technology's LT3965 LED matrix driver makes it easy to move forward with automotive lighting design. Control 8 power switches with I2C with a single IC The basic LED headlamp design uses a consistent LED current, so the brightness is also consistent. But this approach leaves a large part of the LED's potential on paper. Matrix headlamps take advantage of the inherent advantages of LEDs by controlling the brightness of individual LEDs in the LED string. In theory, it is not difficult to use a computer-controlled power switch to control a single LED in an LED matrix, allowing a single LED to be turned on or off, or PWM dimming a single LED to create unique illumination patterns and functions. . Each LED (or a segment of the LED string) requires its own converter or its own parallel power switch. A matrix driver can be built with a traditional driver/converter IC with serial communication, but once the LED matrix requires two or more switches, designing a solution consisting of discrete components becomes challenging Sex, because you need to use a component matrix that is larger than the LED matrix. The LT3965 I2C 8 switch matrix LED dimmer makes it easy to control large or small LED matrices (up to 512 LEDs). Figure 1 shows the LT3965 running on the Linear Technology demo board DC2218. Figure 1: The LT3965 LED Matrix Dimmer Demo Board DC2218 is used as a shield for the LinduinoTM (DC2026). This demo board drives headlights, turn signals, taillights, and decorative lights that can be connected to the Linear Technology graphical user interface via a USB cable for evaluation. 3.5mm ribbon connectors are used to connect ribbon cables to audio and video devices such as headphones, speakers, microphones, and cameras.
