Abstract
A lamp with functions of adjusting an illumination direction is disclosed. A substrate is disposed on a base and includes a through groove. At least one light source is disposed on the substrate. An electronic control unit is disposed in the base. A telescopic member is disposed in the base and is connected to the electronic control unit. The electronic control unit drives the telescopic member to elongate and shorten. A flexible light guiding sheet is connected to the telescopic member. When the electronic control unit drives the telescopic member to elongate, the flexible light guiding sheet protrudes onto the substrate via the through groove of the substrate and deflects toward a specific direction, changing the illumination direction of the light source.

A lamp with functions of adjusting an illumination direction, comprising:
- a base;
- a substrate disposed on the base and comprising a through groove;
- at least one light source disposed on the substrate;
- an electronic control unit disposed in the base;
- a telescopic member disposed in the base and connected to the electronic control unit, wherein the electronic control unit drives the telescopic member to elongate and shorten;
- and
- a flexible light guiding sheet connected to the telescopic member, wherein, when the electronic control unit drives the telescopic member to elongate, the flexible light guiding sheet protrudes onto the substrate via the through groove of the substrate and deflects toward a specific direction, changing the illumination direction of the light source.
A lamp with functions of adjusting illumination directions, comprising:
- a base;
- a substrate disposed on the base and comprising a through groove;
- a first light source disposed on the substrate;
- a second light source disposed on the substrate;
- an electronic control unit disposed in the base;
- a telescopic member disposed in the base and connected to the electronic control unit, wherein the electronic control unit drives the telescopic member to elongate and shorten;
- a first flexible light guiding sheet connected to the telescopic member;
- and
- a second flexible light guiding sheet connected to the telescopic member, wherein, when the electronic control unit drives the telescopic member to elongate, the first and second flexible light guiding sheets protrude onto the substrate via the through groove of the substrate and respectively deflect toward a first direction and a second direction, changing the illumination directions of the first and second light sources.
