Abstract
An underwater safety lighting device for lighting water beneath a surface (4) of the water in a swimming pool is provided. A water-tight light housing (1) is disposable beneath the surface (4) of the water in the pool and has a lens (5) removably attached to a front side (6) of the light housing (1), a light-emitting source (12) is secured within the light housing and a concaved light reflector (9) is secured within the light housing. The light-emitting source (12) is disposed above a conjugate axis (21) of the concave light reflector (9). An aperture (20) is disposed entirely in an upper one-half (21) of the light reflector (9) for receiving the light-emitting source (12). A control housing (2) is disposable out of the water of the pool and has a control device (26). An elongated connector (3) having a lower connector end (28) connects with a light housing connection portion (22) and an upper connector end (29) connects with a support of the pool. A passageway (30) therein passes electrical wires (31) from the power supply housing (2) to the light housing (1).
