INCREASING THE EFFICIENCY LEVEL IN THE USE OF ELECTRICAL ENERGY BY LIGHTING DEVICES

Abstract

The improvement of the LED lamp, which has an increased level of efficiency in the use of electrical energy by lighting devices by implementing direct adaptive control of the current lighting power in accordance with the needs of each specific lighting area of the object, was considered in the article. The proposed LED lamp was created for the purpose of: increasing the efficiency of the LED lighting device; reduction of electrical energy level consumed by the lighting device; remote control of LED lighting according to user algorithms; increasing the reliability of the LED lighting device. This LED lamp belongs to the type of ceiling lamps with passive cooling. The body of the lamp is made of aluminum, the design and dimensions of which are determined in such a way as to ensure long-term operation in the summer without overheating of the LED elements. Control of work and monitoring of parameters is carried out using a wireless interface “Bluetooth”. The proposed design of the LED lamp has the following advantages: the operation of each matrix is controlled by its own driver, which takes into account its unique operating characteristics to ensure optimal parameters; constant control of temperature parameters and protection against overheating, which significantly extends the life of the matrix; constant control of the matrix power supply current and voltage; the ability to control the power of both the entire lamp and each matrix separately; combination of the controller board and the LED matrix; the ability to combine different types of LEDs within one lamp; support of various interfaces in accordance with user requirements; constant monitoring of parameters and detected errors. The concept of an improved LED lamp with advanced information properties based on the STM32 microcontroller, which has an increased level of efficiency in the use of electrical energy by lighting devices, was developed.
