LED ceiling lights are connected to a 220 V network. Any options for the electrical circuit of connecting LEDs are possible (Figs. 38-40). The LEDs 5 are mounted on the circuit board 9 (Fig. 38), on which the insulating layer 31, conductive paths 32 are made. The power supply circuit of the LEDs 5 (Fig. 39) contains wiring 33, may include a transformer 34, to which a rectifier 36 is connected by low-voltage wires 35 and further, the internal wiring 37 are connected in series by the LEDs 5 (Fig. 39). A possible electric circuit using a resistor 38 (Fig.40) ..

The Assembly of the lamp is as follows (11 ... 12).

First, the side walls 1 are assembled in the form of a rectangular or square frame. Then the back wall 3 is assembled, for this, panels 9 with LEDs are mounted on it 5. Then the back wall 3 is installed in the grooves 15 and the translucent window 2 in the grooves 18. If necessary, an external decorative casing is installed 6. this decorative casing is not necessarily included in the delivery .

During operation, they turn on the power switch and the electrical energy for wiring goes to the LEDs 5. (The switch, wiring and electrical power supply circuit of the LEDs 5 are not shown in FIGS. 1 ... 34). The LEDs 5 emit light that passes through the translucent window 2, which has the largest possible size and maximum light transmission. Silicate glass, polystyrene, polycarbonate, polymethyl methacrylate can be used as a material for a translucent window. All body parts are painted with powder dye or enamel in bright colors.

As a translucent coating 8 (Fig.6) can be used a material having a transmittance of from 90 to 95%. The translucent coating 8 can be performed on the lower side of the translucent window 2 or on the upper side. In the latter embodiment, during transportation, the translucent coating 8 is not broken.
