Abstract

A clamping lamp for clamping a monitor comprises a first light source and a clamping body including a second light source, a first clamping component including a first clamping portion and a lamp connection portion, and a second clamping component including a second clamping portion. The lamp connection portion connects with the first clamping portion and the first light source. The first clamping portion leans against a front surface of the monitor and the second clamping portion leans against a back surface of the monitor when the clamping lamp clamps the monitor so the first light source is located above a top surface of the monitor. The first light source emits light toward a first zone that the front surface faces toward. The second light source emits light toward a second zone that the back surface faces toward.

First claim

What is claimed is:

1. A clamping lamp for clamping a monitor, wherein the monitor has a front surface, a back surface, and a top surface connecting with the front surface and the back surface, and the clamping lamp comprises:
a first light source; and
a clamping body comprising:
a second light source;
a first clamping component including a first clamping portion and a lamp connection portion connecting with the first clamping portion, wherein the lamp connection portion connects with the first light source; and
a second clamping component including a second clamping portion;

wherein the first clamping portion is configured to lean against the front surface and the second clamping portion is configured to lean against the back surface when the clamping lamp clamps the monitor, such that the first light source is located above the top surface and the second light source is located below the top surface;
wherein the first light source is configured to emit light toward a first zone that the front surface faces toward when the first light source is turned on, and the second light source is configured to emit light toward a second zone that the back surface faces toward when the second light source is turned on;
wherein the second light source includes a first light-emitting array, a second light-emitting array and a third light-emitting array; the third light-emitting array is disposed between the first light-emitting array and the second light-emitting array; the third light-emitting array is not parallel with the first light-emitting array and the second light-emitting array.

2. The clamping lamp according to claim 1 , wherein the monitor has a top side, a first lateral side and a second lateral side, the third light-emitting array is closer to the top side than the first light-emitting array and the second light-emitting array.

3. The clamping lamp according to claim 2 ,
wherein a first end of the third light-emitting array is connected with the first light-emitting array, and a second end of the third light-emitting array is connected with the second light-emitting array.

4. The clamping lamp according to claim 3 ,
wherein the third light-emitting array is parallel with the top side, the first light-emitting array and the second light-emitting array are parallel with the first lateral side.

5. The clamping lamp according to claim 2 , wherein the first light-emitting array is parallel with the first lateral side and a light-emitting direction of the first light-emitting array has an acute angle with the back surface of the monitor; the second light-emitting array is parallel to the second lateral side and a light-emitting direction of the second light-emitting array has an acute angle with the back surface of the monitor.

6. The clamping lamp according to claim 1 , further comprising:
an light sensor configured to sense an illuminance value of the first zone; and
a processing module connecting with the light sensor and configured to control the luminous intensity of the second light source according to the illuminance value of the first zone so as to make an illuminance value of the second zone lower than the illuminance value of the first zone.

7. The clamping lamp according to claim 6 , further comprising:
a distance sensor disposed on the second clamping portion, wherein the distance sensor is configured to sense a distance between the back surface and a reference object that the back surface faces toward when the clamping lamp clamps the monitor, and the processing module is configured to control the luminous intensity of the second light source according to the distance to make the luminous intensity of the second light source have a positive correlation with the distance.

8. The clamping lamp according to claim 6 , wherein the clamping lamp is adapted to connect with an interface of the monitor to obtain a display brightness value of the monitor, and the processing module is configured to control the luminous intensity of the second light source according to the display brightness value.

9. The clamping lamp according to claim 1 , wherein the third light-emitting array is perpendicular to the first light-emitting array and the second light-emitting array to form a U-shaped arrangement, the opening of the U-shaped is downward.

10. The clamping lamp according to claim 1 , wherein the first light-emitting array is arranged in parallel with the second light-emitting array; one end of the third light-emitting array is connected with the first light-emitting array; and the other end of the third light-emitting array is connected with the second light-emitting array.

11. The clamping lamp according to claim 10 , wherein the clamping lamp further includes a weight component; the first light-emitting array and the second light-emitting array are respectively arranged on two sides of the weight component, the third light-emitting array is arranged on a top side of the weight component; a light-emitting direction(s) of the first light-emitting array, the second light-emitting array and/or the third light-emitting array has an angle with an adjacent side surface of the weight component; and the angle is acute, the light-emitting directions of the first light-emitting array and the second light-emitting array are different.

12. The clamping lamp according to claim 1 , wherein light-emitting directions of the first light-emitting array and the second light-emitting array are different.

13. A clamping lamp for clamping a monitor, wherein the monitor has a front surface, a back surface, and a top surface connecting with the front surface and the back surface, and the clamping lamp comprises:
a first light source;
a clamping body comprising:
a second light source;
a first clamping component including a first clamping portion and a lamp connection portion connecting with the first clamping portion, wherein the lamp connection portion connects with the first light source; and
a second clamping component including a second clamping portion;

a lamp interface configured to connect with an interface of the monitor to receive a setting value; and
a processing module configured to control the luminous intensity and a color value of the second light source according to the setting value, wherein the setting value is relevant to a real-time display screen of the monitor;
wherein the first clamping portion is configured to lean against the front surface and the second clamping portion is configured to lean against the back surface when the clamping lamp clamps the monitor, such that the first light source is located above the top surface and the second light source is located below the top surface;
wherein the first light source is configured to emit light toward a first zone that the front surface faces toward when the first light source is turned on, and the second light source is configured to emit light toward a second zone that the back surface faces toward when the second light source is turned on;
