The LED flame lamp on the market is a popular name, it is also called LED torch lamp. It is the most popular type of lighting used as an atmosphere in overseas, and is widely used in weddings, churches, villas, coffee shops and other places. The flame lamp development program launched by the MCU Solution Network, the main control chip adopts the MCU EN8F883, the flame is realistic and beautiful, and there are multiple flashing modes.
1. Principle of flame lamp development plan
The flame light is a group of multiple LED lights. The driving circuit is controlled by the PWM signal of the LED torch light IC to make the LED lamp beads show the flickering effect of flame. The lamp beads generally use a color temperature of 3000K, and the lamp board of the LED flame lamp generally uses a flexible PCB board, which is bent into a cylindrical shape and then welded together.
2. Introduction of flame lamp development plan
The flame lamp development program provided by the MCU program network has two power supply modes: 220V and 3.7V. There are three flashing modes: flame, breathing, and constant light.

The main control chip EN8F883 microcontroller is a low-cost, high-performance, 8-bit, fully static flash CMOS microcontroller. With RISC architecture, there are only 37 single-word/single-cycle instructions. The whole MCU is a dual-clock system with internal high-speed 16M and internal low-speed 32K clocks. The instruction cycle can be set to 4 times or 2 times the clock cycle through OPTION. The performance of EN8F883 devices is much higher than similar products at the same price. The easy-to-use and easy-to-remember instruction set greatly reduces development time.
