The light reflecting surface (106) is configured to perform a reflecting operation on the first light and the second light, and the first light and the second light after the reflecting operation are emitted from the light emitting surface (104). Also provided is a cosmetic mirror with a light guiding device (10). The light guiding device (10) and the cosmetic mirror having the light guiding device (10) are respectively provided with illuminants at both ends of a light guiding body (110), so that the light generated by the illuminant is transmitted from opposite ends of the light guiding body (110) to achieve the purpose of improving the uniformity of the emitted light.
B: A backlight module (100), comprising: a light guide plate (1), which includes a light entrance surface (11) and a light exit surface (12) as well as a light propagation guide rail (13), the light entrance surface (11) comprises a first light entrance area (111) and a second light entrance area (112) adjacent to the first light entrance area (111), the light propagation guide rail (13) extends from the first light entrance area (111) to inside of the light guide plate (1), and is used to surround and form a light propagation channel (130), and a notch (131) facing the light exit surface (12) is formed on the light propagation guide rail (13); a light bar (2), which includes a first light source (21) and a second light source (22), the first light source (21) is directed to the first light entrance area (111), so that the light of the first light source (21) enters the light propagation channel (130), and is reflected by the light propagation guide rail (13), and is then sequentially emitted from the notch (131) and the light exit surface (12), the second light source (22) is directed to the second light entrance area (112,) so that the light of the second light source (22) enters the light guide plate (1), and is then emitted from the light exit surface (12); a control circuit (3), which is electrically connected to the first light source (21) and the second light source (22), and used to control the switching state of the first light source (21) and the second light source (22). A liquid crystal display (200) applying the backlight module (100). The backlight module (100) and the liquid crystal display (200) can achieve partition display.
C: A light emitting device (100) and a vehicle lamp (200) using same. The light emitting device (100) comprises two light sources (111, 112), a first light conductor (121) and a second light conductor (122) arranged side by side, and a light guide element (130). The first light conductor (121) comprises a first light incident surface (1211) and a first end surface (1212); the second light conductor (122) comprises a second light incident surface (1221) and a second end surface (1222); the first light incident surface (1211) and the second light incident surface (1221) are arranged on the same side; the first end surface (1212) and the second end surface (1222) are arranged on the same side; the two light sources (111, 112) are respectively disposed on the first light incident surface (1211) and the second light incident surface (1221); and the light guide element (130) is disposed on the first end face (1212) and the second end face (1222), wherein the first light conductor (121) comprises a light exit portion (123), and the light exit portion (123) is provided on the first end face (1212) close to the first light conductor (121). Two light paths are formed by providing the two light conductors (121, 122) arranged side by side and the light guide element (130), so that the light emitted by the two light sources (111, 112) is respectively conducted and converged to the light exit portion (123), thereby improving the luminous flux of the light exit portion (123) and reducing the optical expansion amount of the entire light emitting device (100).
D: Disclosed is a light supplementation device (100), comprising a mounting plate (6) as well as a first lamp bank (1) and a second lamp bank (2) disposed thereon. Light emitted from a first light emitting element (11) of the first lamp bank (1) exits from a first light-exiting surface (122) of a first prism (12), the first prism (12) having a first prism angle. Light emitted from a second light emitting element (21) of the second lamp bank (2) exits from a second light-exiting surface (222) of a second prism (22), the second prism (22) having a second prism angle. The first prism angle is different from the second prism angle such that light from the first lamp bank (1) and light from the second lamp bank (2) exit to different directions so as to supplement light for different ranges (51) of an area subject to light supplementation (5), thereby avoiding nonuniform brightness caused by light supplementation in a single direction. The mounting plate (6) realizes the combination and assembly of lamp banks with different light exiting directions, avoiding the complexity of respectively installing a plurality of lamp banks.
