Using LED digital clock to make timing switch circuit 2

The "Plan for Private Placement of A-Shares" disclosed by Leman Optoelectronics (300162.SZ) on the evening of April 24 shows that the company plans to privately place no more than 104,853,009 shares, with a total amount of funds raised not exceeding 380 million yuan, of which 270 million yuan will be invested in the "

　　The English name of LED wall washer lamp is Ledwashwalllamp, also known as linear LED floodlight, etc. Because of its long strip shape, most of them are wall washer lamps with aluminum shell, also known as LED aluminum strip lamp and LED linear lamp. It is mainly used for architectural decorative lighting, and is al

In recent years, coal mine production safety accidents have occurred frequently, resulting in the serious phenomenon of "major accidents are frequent and minor accidents are continuous", which not only seriously threatens the lives of miners, but also seriously restricts economic development. Underground coal mine

The application of LED (light-emitting diode) can be said to be everywhere. As a semiconductor luminescent material, compared with other luminescent materials, LED has the advantages of being green, efficient, reliable and durable, which makes other luminescent materials pale in comparison. With t

LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power supply structure of choice for most LED drivers because these devices can achieve isolation between the LED and the AC lin

One of the fastest growing areas of LED applications is effect lighting, also known as architectural lighting. Effect lighting can use RGB LEDs, which use three chips, each responsible for generating a color of light (red, green, and blue). Another way to generate different colors of light is to use red, green, and

In the header file of the myled bare metal program of mini2440, the option.ini header file defines the relevant configuration of the chip (Configuration of memory-related register values. The configuration of registers here will eventually be called by init.s to initialize the CPU) ;===================================

As a new force in light sources, LEDs emit light in a completely different way from traditional light sources. They emit light by using the recombination of electrons and holes in the semiconductor PN junction. The difference in the way they emit light determines the essential difference between LEDs and tradition
