Известные решения, направленные на обеспечение данного требования, усложняют конструкцию узла отвода тепла, что приводит к увеличению габаритов и массы изделия, увеличению его материалоемкости. In modern lighting devices made on powerful light emitting diodes, it is very important to ensure the correct thermal regime during their operation. Known solutions aimed at ensuring this requirement complicate the design of the heat removal unit, which leads to an increase in dimensions and mass of the product, an increase in its material consumption.
Другой особенностью осветительных устройств со светодиодными источниками света является излучение светового потока в разных направлениях с различной интенсивностью, что оценивается по световому ощущению глаза человека.

The described device cannot be used in subway tunnels, because with the minimum dimensions of the product it is difficult to form a light curve, the shape of which would ensure the avoidance of blindness of electric train drivers.
Кроме того, к недостаткам ближайшего аналога относятся: - перегрев светодиодов при длительной эксплуатации и, как следствие, выход устройства из строя; In addition, the disadvantages of the closest analogue include: - overheating of the LEDs during long-term operation and, as a result, the failure of the device;
- отсутствие эффективного теплоотвода; - lack of effective heat sink;
