Lighting module
A lighting module ( 10 ), for example of the LED type, for mounting on a rail comprises a circuit board ( 12 ) for carrying one or more light radiation sources (L), and a support structure ( 14 ) with a first side ( 14 A) facing the rail and carrying the aforementioned circuit board ( 12 ) and a second side ( 14 b ) situated on the opposite side to the rail and carrying one or more lenses ( 16 ) for the light radiation sources (L). The support structure ( 14 ) carries one or more flexible electrical contacts ( 18 ) having a first end ( 18 a ) protruding from the first side ( 14 a ) of the support structure ( 14 ) for making contact with an electrical line (T) provided on the rail (R) and a second end ( 18 b ) which extends towards the circuit board ( 12 ) so as to provide electrical contact for the light radiation source or sources (L).
1. A lighting module for mounting on a rail having at least one electrical line extending therealong, the module comprising:
a circuit board for carrying at least one light radiation source; and
a support structure with a first side facing the rail and carrying said circuit board and a second side situated on the opposite side to the rail and carrying at least one lens for said at least one light radiation source;
wherein said support structure carries at least one flexible electrical contact having a first end protruding from said first side of said support structure for making contact with said at least one electrical line and a second end which extends towards said circuit board so as to provide electrical contact for said at least one light radiation source.
2. The lighting module of claim 1 , wherein said support structure comprises complementary arm portions protruding from said first side and capable of engaging with said rail.
3. The lighting module of claim 2 , wherein said arm portions protrude from said first side beyond said circuit board so as to define a heat dissipation space.
4. The lighting module of claim 3 , further comprising an auxiliary heat sink having a body portion inserted in said heat dissipation space and at least one finned portion extending from said body portion away from said support structure.
5. The lighting module of 4 , wherein said auxiliary heat sink has a U-shaped cross section with two finned portions extending on opposite sides of said body portion astride said support structure.
6. The lighting module of claim 2 , wherein said complementary arm portions are capable of engaging with said rail by means of snap-engagement.
7. The lighting module of claim 1 , wherein said support structure has a channel shape with a central wall carrying said at least one lens on said second side and side walls extending from said central wall so as to carry said circuit board on said first side.
8. The lighting module of claim 1 , wherein said at least one flexible electrical contact comprises a single piece with a loop portion anchored to said support structure and a first arm and a second arm extending from said loop portion with the distal portions of said first arm and said second arm forming said first end and said second end, respectively.
9. The lighting module of claim 8 , wherein said first arm is longer than said second arm.
10. The lighting module of claim 1 , wherein said first end has a slider-like shape.
11. The lighting module of claim 1 , comprising said at least one light radiation source in the form of an LED light radiation source.
12. The lighting module of claim 1 , wherein said first end and said second end have a slider-like shape.
