Illuminating device with light guiding frame

A light emitting device, comprising:

• a light guiding frame having a recess, wherein the recess has a light-emitting opening, and the light guiding frame comprises:
• a first light guiding structure;
• a second light guiding structure connected to the first light guiding structure;
• and
• a light source disposed on a bottom of the recess and having a light-emitting surface;
• wherein the first light guiding structure is extended from the light source along a direction away from the light-emitting surface and the light-emitting opening, and the second light guiding structure is extended from the first light guiding structure along a direction away from the light-emitting surface but close to the light-emitting opening;
• and
• wherein the first light guiding structure comprises a plurality of light guiding sections, the n+1th light guiding section is farther away from the light-emitting surface of the light source than the nth light guiding section, the angle between the n+1th light guiding section and the light-emitting surface is smaller than the angle between the nth light guiding section and the light-emitting surface, and n is a positive integer.
