Investigation of efficiency and quality of functioning of led lighting elements of electrical systems at the maximum permissible ambient temperature

Based on the results of the study of the elements of the electrical system, the operability and quality of their functioning are determined by the example of the use of LED filament lamps for lighting during their continuous operation at the maximum permissible ambient temperature equal to 50 °С.

THE PURPOSE. The relevance of this work is determined by the lack of information about the operability and quality of functioning of filament LED lamps during their continuous operation in conditions of elevated ambient temperature, taking place in boiler-turbine shops of thermal power plants, foundries of factories, bakeries of bakeries, in the tunnels of coal mines and divisions of other enterprises. It is established that the working life of the Gauss LED filament lamps with a power of 10 W, containing 4 filaments, is 70-75 days, and with 8 filaments only 22-24 days. Degradation of filament lamps with 8 filaments at the maximum permissible ambient temperature of 50 °С. occurs at a rate of 0.45-0.50 % per day. It is shown that a filament LED lamp with 4 filaments, if it is operated for 4.5 hours a day in conditions of elevated ambient temperature, can work for almost more than one year.

METHODS. The resource of filament and typical LED lamps of different power is considered in comparative terms when they are operated at a relatively high ambient temperature.

RESULTS. It is established that a 10 W filament LED lamp with 4 filaments has an energy resource, as well as a high-quality standard LED lamp. At the same time, the temperature of its body is no more than 40 °С, which is almost 2 times less. By increasing the distance between the filaments due to the use of a smaller number of filaments, it is possible to increase the power supply by 2 times and the corresponding luminous flux by 1.5 times.

CONCLUSION. In preliminary experiments with a filament lamp of the new design of the Diall model, it was found that the use of longer filaments (45 mm) in it, instead of the previously used ones (30 mm), allows to increase the quality of their functioning by about 4 times when they are operated under the same ambient temperature conditions.
