The invention provides an LED (
light emitting diode) illuminating lamp for a glass
curtain wall. The lamp provided by the invention comprises a
metal bottom shell, an upper shell and a plurality of
light source modules which are installed on the inner bottom of the
metal bottom shell, wherein the upper shell and the
metal bottom shell are buckled into a whole; the upper shell is provided with a plurality of pairs of front light-emitting holes, through holes and left and right light-emitting holes at intervals, and each front light-emitting hole is provided with a lens; each
light source module comprises a shell, a built-in control-driven circuit, a forward
light emitting device above the shell and a rotating seat arranged on one end of the shell, a bidirectional
light emitting device is installed on the end face of the rotating seat, a rotatable inclined light-transmitting device is installed on the rotating seat, and the head of the inclined light-transmitting device is exposed from the through holes of the upper shell; light rays emitted from the bidirectional
light emitting device shoot up from the corresponding left and right lenses to serve as a pixel
point light source, and the light rays emitted by the forward light emitting device
shoot up from the lens to serve as a forward
background light source; and when the bidirectional light emitting device and the forward lightemitting device are in a nonoperating state, the light rays from the inclined light-transmitting device
shoot up in an inclined upward direction along the right sides of the
light source modules to serve as an inclined
background light source.
