Described circuit board is made of substrate, conducting wire and insulating protective layer etc.; the conducting wire is made up of three series arms; three series arms connect R, G, B three primary colors LED light source respectively, because common each series arm of the otherness of resistance also need be connected a resistance so that reach the electrical quantity and the optical parametric of design in the led light source.

Described led light source is that LED package forms, and comprises R, G, B three primary colours.

Described reflector is provided with some in order to get via hole through the LED light-emitting area, for improving illumination effect at photophore reflective surface plating reflector layer by aluminium alloy or plastic mould pressing moulding on it.

Described transparent shroud is made by high light transmittance ratio glass or resinous material, and its size just is assemblied in the lamp shell opening part of being made up of radiator and left and right sides end cap.

Good effect of the present utility model: the utility model curtain wall lamp outer setting has radiating fin, traditional LED curtain wall lamp of comparing increases area of dissipation with other LED Landscape Lamps, improve radiating condition, guarantee light efficiency and life-span under the lower junction temperature thereby LED is operated in; Simultaneously, regulate each branch current by controller and can realize multiple photochromic variation, some curtain wall lamp forming arrays like this are arranged and can be realized Presentation Function, are specially adapted to large-scale square and building brightening and show.
