at least one light emitting source; and at least one connector adapted to connect in series two adjacent lamps, wherein the at least one connector is placed at the lower wall and a longitudinal axis of the connector, or a direction for plugging or unplugging the connector so as to connect the two adjacent lamps, is oriented orthogonally with respect to the longitudinal axis of the lamp and to the lower wall, and wherein the lamp is formed by two channel-shaped shells, one of the two channel-shaped shells being an upper shell having an open side facing a lower shell, and the other one of the channel-shaped shaped shells being the lower shell having an open side facing the upper shell, the upper shell having divergent lateral walls, a distance of the lateral walls at an open side being larger than a distance of the lateral walls of the lower shell, the upper shell overlapping the lower shell for a length of the lateral walls of the lower shell in a direction transverse to a longitudinal axis of the said upper and lower shells. ### Claim 2 (depends on 1) The lamp according to claim 1, wherein a transversal section of said lamp has an elliptical or polygonal shape which is inscribable in an ellipsoid, the elliptical or the polygonal shape being oriented with a major axis thereof perpendicular to the ground. ### Claim 3 (depends on 2) The lamp according to claim 2, wherein at least one of the upper wall of the lamp or of a minor axis of the elliptical or polygonal shapes has a dimension, in a direction transversal to the longitudinal axis of the lamp, which is greater than a corresponding dimension of the lower wall and/or of the at least one connector. ### Claim 4 (depends on 1) The lamp according to claim 1, wherein said at least one light emitting source emits a light cone oriented with an angle between 30° to 45° towards the ground. ### Claim 5 (depends on 1) The lamp according to claim 1, wherein said at least one light emitting source emits a light cone oriented with an angle between 0° to 60° towards the ground. ### Claim 6 (depends on 1) The lamp according to claim 1, wherein the upper and lower shells are provided respectively with an inner hook-shaped rim and with a groove open towards an outside for engaging the hook-shaped rim, the hook-shaped rim and the groove having downward inclined surfaces oriented from an inside to the outside of the lamp and forming water discharging surfaces projecting outwards from the lateral walls of the lower shell. ### Claim 7 (depends on 1) The lamp according to claim 1, further comprising: a metal frame; a couple of gaskets; and a couple of printed circuit boards (PCB), wherein the at least one light emitting source comprises a plurality of LEDs mounted at a regular distance. ### Claim 8 (depends on 7) The lamp according to claim 7, wherein said metal frame comprises a couple of wings, which keep said PCB, on which said plurality of the LEDs are mounted, at a desired inclination. ### Claim 9 (depends on 7) The lamp according to claim 7, wherein inside said metal frame there is provided a power supply, and wherein heat emitted by said power supply and said lamp is used to heat said greenhouse. ### Claim 10 (depends on 7) The lamp according to claim 7, further comprising providing each of the at least two lamps with a transparent cover protecting the light emitting source of each lamp. ### Claim 11 (depends on 1) The lamp according to claim 1, wherein electrical supply is performed via a feed-through wiring, so that a first lamp of a series of lamps is connectable only to mains. ### Claim 12 (depends on 1) The lamp according to claim 1, wherein said at least one light emitting source emits light having a wavelength in a range of 630-670 nm. ### Claim 13 (depends on 1) A method of lighting plants grown in a greenhouse, comprising the following steps: providing at least two lamps according to claim 1; hanging said at least two lamps; and connecting said at least two lamps in series; and placing ends of said at least two lamps in contact with each other. ### Claim 14 (depends on 13) The method according to claim 13, wherein connecting said at least two lamps comprises connecting with a feed-through wiring. ### Claim 15 (depends on 13) The method according to claim 13, further comprising generating heat with the at least two lamps that does not exceed 55° C. ### Claim 16 (depends on 1) The lamp according to claim 1, wherein said at least one light emitting source emits light having a wavelength is in a range of 400-500 nm. ### Claim 17 (depends on 1) The lamp according to claim 1, wherein said at least one light emitting source emits a light cone oriented with a 30° angle towards the ground.
