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.
Description
technical field [0001] The invention relates to a lamp with the function of adjusting the lighting direction, in particular to a lamp which can arbitrarily adjust the lighting direction or angle according to the actual lighting requirement. Background technique [0002] Generally speaking, current lamps can only provide lighting in a fixed or single direction, but cannot change the direction or angle of the lighting. [0003] see Figure 1A and Figure 1B , an existing lamp 1 mainly includes a transparent tube body 10 , a substrate 20 , a plurality of light sources 30 and a reflector 40 . [0004] The substrate 20 is disposed in the transparent tube body 10 . [0005] A plurality of light sources 30 are disposed on the substrate 20 . [0006] The reflector 40 is connected to the transparent tube body 10 , and the reflector 40 is disposed on the plurality of light sources 30 . [0007] The light emitted by the light source 30 will be reflected by the reflection plate 40 a...
