Abstract

The lighted chair base comprises a base plate, a base case, a power source, a controller and at least one light emitter. The base case is coupled to the base plate, and comprises an accommodation space. The power source is disposed on the base plate and located within the accommodation space. The controller is located within the accommodation space and electrically coupled to the power source. The at least one light emitter is located within the accommodation space and electrically coupled to the controller. The lighted chair back is also disclosed, comprising a main body, a power source, a controller and at least one light emitter. The power source is coupled to the main body. The controller is electrically coupled to the power source. The at least one light emitter is disposed on the main body and electrically coupled to the controller.

Claims

1. A lighted chair base, comprising:

a base plate penetrated with at least one slot, and the at least one slot has a top opening and a bottom opening opposite to the top opening;

a base case, coupled to the base plate, comprising an accommodation space;

a power source disposed on the base plate and located within the accommodation space;

a controller located within the accommodation space and electrically coupled to the power source;

at least one light emitter located within the accommodation space and electrically coupled to the controller; and

at least one light guider, disposed on the base plate, shielding the top opening of the at least one slot, wherein the at least one light guider is capable of guiding light emitted from the at least one light emitter to illuminate an outside area through the top opening and the bottom opening of the at least one slot.

2. The lighted chair base as claimed in claim 1, wherein the base plate comprises a central and a plurality of peripheral base plates.

3. The lighted chair base as claimed in claim 2, wherein the plurality of peripheral base plates comprises five peripheral base plates.

4. The lighted chair base as claimed in claim 3, wherein the lighted chair base comprises five light guiders disposed on the five peripheral base cases correspondingly.

5. The lighted chair base as claimed in claim 2, wherein the base case comprises a central base case and a plurality of peripheral base cases.

6. The lighted chair base as claimed in claim 5, wherein the plurality of peripheral base cases comprises five peripheral base cases.

7. The lighted chair base as claimed in claim 6, wherein the central base plate and the plurality of peripheral base plates are orthographic projections of the central base case and the plurality of peripheral base cases correspondingly.

8. The lighted chair base as claimed in claim 1, wherein the light emitter comprises a light emitting surface, the light guider comprises a front surface, a rear surface, a right side surface, a left side surface, a top surface and a bottom surface facing the base plate, wherein the light emitting surface faces the bottom surface of the light guider.

9. The lighted chair base as claimed in claim 1, wherein the light emitter comprises a light emitting surface, the light guider comprises a front surface, a rear surface, a right side surface, a left side surface, a top surface and a bottom surface facing the base plate, wherein the light emitting surface faces the front surface of the light guider.

10. The lighted chair base as claimed in claim 1, wherein the light emitter is a light emitting diode.

11. A lighted chair back, comprising:

a main body comprising a first light guider, a front side, and a rear side;

a power source coupled to the main body;

a controller electrically coupled to the power source;

first light emitters disposed at the front side of the main body and electrically coupled to the controller;

second light emitters disposed at the rear side of the main body, electrically coupled to the controller, and coupled with the first light guider;

at least one front frame disposed between the front side of the main body and the first light emitters; and

at least one second light guider disposed between the at least one front frame and the first light emitters, and the first light guider and the at least one second light guider guide light emitted from the first light emitters and the second light emitters toward the front side and the rear side of the main body.

12. The lighted chair back as claimed in claim 11, further comprising a rear frame disposed between the rear side of the main body and the at least one light emitter.

13. The lighted chair back as claimed in claim 11, wherein each of the first light emitter and the second light emitter is a light emitting diode.

14. The lighted chair back as claimed in claim 11, wherein the power source is a rechargeable battery.
