The system of lamps of LEDs of 4,0w connected directly to the mains A.C.

摘要

The system of lamps of LEDs 4.0W connected directly with the AC network the present invention patent concerns is characterized by function as semiconductor connected direct current mains voltage alterNothing, or AC, avoiding the use of electrical source, being formed by a plate composed of 88 transponders distributed in 04 cells (2) with 22 microchips / each, operating with 2,5v in each microchip.And, each LED lamp (3) is composed of a heat sink (4), a ring (5) in aluminum naval and cables (6) of coatings siliconizados,Each cell (2) is composed of 22 transponders operating with 2,5v and amperage of 40mA when 110V / AC and 20mA when 220V / AC.In the case of the network be 110V / AC, each LED (3) 4,0w / AC x110v, which is composed by 4 cells (2) of 22 microchips, these cells (2) are connected in parallel, two in two trunks,And in each trunk are connected to two cells (2) in series.Therefore, the amperage of 40mA is subdivided into each trunk at 20mA for each one; in the case of the network be 220V / AC, each LED (3) 4,0w / AC x 220V, which is composed by 4 cells (2) of 22 transponders,As these cells connected in series by applying the Voltage 220VAC and amperage of 20,0ma.Where and as example, the sum of the voltage of each microchip will add up to the total 220VAC, and the same amperage controlled 20,0ma.Finally, each lamp (3) 4,0w / AC is formed by: a heat sink (4) made of extruded aluminum with 37,20 mm diameter x 40 mm,The length and an area of 160 cm square); a ring (5) in aluminium shipbuilding of 40 mm x 2.00 mm.Receiving the plate led 4,0wac,Which is fixed on the heat sink (4) by means of two screws self broaching; cables (6) of coatings siliconizados with electrical isolation of 750 volts and resistant to a temperature of 200 degrees centigrade, and the LED (3) 4,0w / AC itself, which is mounted in the plate with other electronic components to correct parameters of the power supply.
