ABSTRACT:
A multi-purpose lamp (10) for outdoor use provides, as desired, a function of a pagoda lamp or of a projections lamp, or of a combined pagoda-projecting lamp.
It includes a pole (101) for insertion into the ground, a support 102 mounted on the pole (101) in desired angular position, a bulb (107) within the support (102), a lens (104) mounted on the support (102) above the bulb (107), a convex-concave reflector (113) mounted within the support (102) and disposed below the bulb (107), and two shades (105, 106) mounted on the support (102). The shades (105) is a pagoda-type shade which comprises another convex-concave reflector (117), so as, when the pagoda-type shade (105) is mounted on the support (102) to provide a pagoda lamp performance, the reflectors (113, 117) form a pair of spaced-apart convex-concave parabolic reflectors substantially parallel to each other.
The shade (106) is a ring-type shade. When the ring-type shade (106) is mounted on the support (102), the lamp (10) performs as a projecting lamp. When the ring-type shade (106) is mounted on the support (102), and the pagoda-type shade (105) is mounted above the ring-type shade (106), the lamp (10) performs as a combined pagoda-projecting lamp.
At least one surface (120, 121) of at least one reflector (113, 117) may include a plurality of reflecting facets (122), hereby providing different illumination patterns.
