A lighting device (10) includes:
- a channel-shaped elongate profiled body having a central or web portion (12) and two side portions (120) sidewise of the web portion (12), a profiled body (12, 120) having mutually opposed undercuts (122) opening inwardly of the channel shape of profiled body (12, 120), and
- a light radiation source assembly (16) including an elongate support board (16a) carrying one or more light radiation sources, e.g. LED sources (16b), the support board (16a) having longitudinal sides extending into the said undercuts (122), wherein the light radiation source assembly (16) is retained by the channel-shaped profiled body (12, 120). Some embodiments may include:
- a first sealing mass (14) located between the web portion (12) of the profiled body (12, 120) and the light radiation source assembly (16),
- a second sealing mass (18) on the face of the support board (16a) opposed to the web portion (12) between one and the other said side portions (120). |
