An illumination device includes a housing, a first light-emitting element, a second light-emitting element, a substrate, and a reflector. The housing has a first light-outlet portion and a second light-outlet portion separated from each other. The first light-emitting element is disposed in the housing and suitable for emitting a first beam. The second light-emitting element is disposed in the housing and suitable for emitting a second beam emitted from the second light-outlet portion. The substrate is disposed in the housing and electrically connected to the first light-emitting element and the second light-emitting element. The reflector is disposed in the housing and located on a transmission path of the first beam. The reflector is suitable for reflecting the first beam to the first light-outlet portion.

Illumination device

A light source module includes a light source and a reflective element. The light source has a light emitting surface. The reflective element is disposed on a transmission path of an illumination light beam emitted from the light source. The illumination light beam reflected by the reflective element is irradiated on a target plane. The reflective element includes a first reflective surface and a second reflective surface. The first reflective surface is disposed towards the light emitting surface of the light source, and is a plane. The second reflective surface bendably extends from the first reflective surface.

Light source module

An anti-peep display device includes a display module and an anti-peep module disposed on the display module. The anti-peep module includes the following features. The first light incident surface faces the display surface, the second and third light incident surfaces are located on opposite sides of the first light incident surface, the first condensing portion is disposed corresponding to the second light incident surface and the first light source, the second condensing portion is disposed corresponding to the third light incident surface and the second light source, the first and second condensing portions convert beams of the first and second light sources into anti-peep beams with a beam angle less than 10 degrees, and the optical microstructures reflect the anti-peep beams and exit the anti-peep beams from the light guide plate. The present invention also provides an anti-peep method applicable to the anti-peep display device.
