Abstract

A slim OLED lamp is provided, which may include a lamp holder, a support, and a base. The support connects the base to the lamp holder. When the lamp holder, support, and base are folded to be in the same plane, the lamp holder, the support, and the base can be close to and adjacent to one another. A light-emitting unit manufactured by the organic light-emitting technology can be plugged into the lamp holder, so the light-emitting unit can be conveniently replaced. There is at least one rotation direction between the support and lamp holder, so the freedom degree of the illumination range of the light-emitting unit can be increased. The base includes a control unit applicable to various light-emitting units with different rating currents so as to adjust the brightness thereof.

Claims

1. A slim OLED lamp, comprising:

a support;

a base connected to one end of the support and provided with a control unit capable of providing different levels of current; and

a lamp holder connected to the other end of the support and provided with a slot adapted to receive a light-emitting unit manufactured by an organic light-emitting device technology;

wherein both the base and the lamp holder are pivotally rotated about the support such that the lamp holder, the support and the base are compact in a plane.

2. The slim OLED lamp of claim 1, wherein a bi-directional hinge having a pivot axis is configured between the support and the base, whereby the support and the base are able to rotate about the pivot axis, respectively;

and a multi-directional hinge having a plurality of rotation axes is configured between the support and the lamp holder such that the support and the lamp holder are able to rotate about one of the plurality of rotation axes, respectively.

3. The slim OLED lamp of claim 2, wherein the lamp holder comprises:

an upper cover; and

a lower cover assembled with the upper cover to form the slot therebetween and to partially house the multi-directional hinge.

4. The slim OLED lamp of claim 3, wherein the lamp holder further comprises:

a mirror unit provided on a top surface of the upper cover; and

a transparent unit provided at the bottom of the lower cover;

wherein light emitted by the light-emitting unit is transmitted through the transparent unit.

5. The slim OLED lamp of claim 3, wherein shapes of two sides of the slot are different from each other and match shapes of two sides of the light-emitting unit, respectively.

6. The slim OLED lamp of claim 3, further comprising an electrode portion provided at the bottom of the upper cover, wherein the electrode portion is connected to a circuit module of the light-emitting unit and further coupled to the control unit via a signal wire.

7. The slim OLED lamp of claim 2, wherein the base further comprises:

an upper base cover;

a lower base cover integrally combined with the upper base cover to form an accommodating space;

a weight balancing unit, mounted at a center position of the lower base cover in the accommodating space;

a power supply unit disposed around the weight balancing unit in the accommodating space; and

a touch control unit disposed around the weight balancing unit in the accommodating space;

wherein the power supply unit is powered by an external power source to further power the control unit, and the control unit powers the light-emitting unit and the touch control unit according to a control requirement thereof, and takes a control action according to a touch status of the touch control unit.

8. The slim OLED lamp of claim 1, wherein the lamp holder, the support and the base form a rectangle, circular, elliptical or polygonal shape in the plane.
