7 Segment LED :: Limiting main circuit of LED driver

It should have its own characteristics of high partial voltage and low power consumption. Otherwise, the higher efficiency LED will greatly reduce the overall system efficiency due to too much power consumption of the driving circuit. As far as possible, resistance or series voltage regulator circuit is not used as the current limiting main circuit of LED driver.

The blue LED substrate is mounted in a bowl-shaped reflecting cavity and covered with a thin layer of resin mixed with YAG, approximately 200-500nm. Part of the blue light emitted by the LED substrate is absorbed by the phosphor, and the other part of the blue light is mixed with the yellow light emitted by the phosphor to obtain white light. For InGaN/YAG white LEDs, by changing the chemical composition of the YAG phosphor and adjusting the thickness of the phosphor layer, the color temperature of 3500-10000K can be obtained.

LED (or single lamp) is generally composed of a single LED wafer, reflective bowl, metal anode, metal cathode, outsourcing with light transmission, concentrating ability of epoxy resin shell. One or more (different color) single lights can be used to form a basic pixel. Due to high brightness, it is often used for outdoor LED display. LED lattice module. The matrix is composed of a number of LED wafers and is enclosed in a plastic shell with epoxy resin. Suitable for row scanning drive, easy to form high density LED display, mostly used for indoor LED display.

From the current technology point of view, each LED sensor has certain limitations, whether it is a radar scheme or a camera scheme, there are shortcomings, therefore, multi-sensor fusion is a current development trend: the advantages and disadvantages of the fusion of the two, foggy days, rainy days can also play a role, but involving two sets of systems, the means of implementation are more complex. Intelligent sensing refers to the self-developed low-latency, high-reliability automotive S0C (ARM+GPU) intelligent processing system.
