LED street and park lighting lamp based on super-powerful 20W LED matrices -DX4, KH-SL60/3 .
The main advantage of this lamp is the use of a new type of LEDs, with a power of 20 W each for the SL60/3 series. This has allowed us to significantly reduce the energy consumption of the lamp, while improving the light output and beam opening characteristics.
Previous experience in creating LED street lamps has shown that the main problem with the introduction of LED street lamps is their high initial cost. The payback of the product usually occurs no earlier than the 4th year of operation, even in the conditions of rapidly rising electricity prices. Therefore, the main task in developing this product was to minimize the initial and operating cost of the product in order to reduce the payback period to one year. To reduce the cost of the product, in this development we abandoned expensive individual cases, using a standard case and a high-quality needle radiator made of AD0 alloy (GOST 4784-97), which has an extremely high level of heat transfer. Thanks to this, it was possible to reduce the operating temperature of the matrix crystals to a level below the permissible limits, which in turn has a positive effect on the service life of the light sources.
The essence of the calculations performed is shown in the figure below.

Notes
1 Categories of city streets and roads according to their functional purpose are adopted in accordance with the classification of Chapter SNiP 2.07.01.
2 Road surfaces are classified as improved, transitional or lower types according to the classification.
The average brightness of the pavement surfaces adjacent to the roadway of streets, roads and squares must be no less than half the average brightness of the roadway surface of these streets, roads and squares, given in Table 11.
The ratio of the minimum brightness of the coatings to the average value must be no less than 0.35 for average brightness standards of more than 0.6 cd/m2 and no less than 0.25 for average brightness standards of 0.6 cd/m2 and below.
The ratio of the minimum brightness of the surface to the maximum along a traffic lane must be no less than 0.6 with an average brightness standard of more than 0.6 cd/m2 and no less than 0.4 with an average brightness standard of 0.6 cd/m2 and below.
