When the light body is in a power-on state, the control assembly controls the light avoiding system not to work; and when the light body is in a power-off state, the control assembly controls the light avoiding system to implement a light avoiding action to make the stage light to avoid the sunlight.

(9) As shown in FIG. 2, the light body comprises a light head 1, a light base 2, and a driving electric motor 5 that drives the light head 1 to rotate relative to the light base 2, and the light avoiding action is that the control assembly controls the driving electric motor 5 to rotate so that the light head 1 avoids sunlight.

(10) With reference to FIG. 3, the light avoiding system comprises a gravity sensor 3 for detecting a gravity direction of the stage light, and the control assembly comprises a main controller 4 for calculating an included angle α between the direction of the light head 1 of the stage light and the gravity direction. When α is within the range of a first included angle, the main controller 4 controls the driving electric motor 5 to drive the light head 1 to rotate, and adjusts the angle of α to be within the range of a second included angle, wherein the first included angle is an included angle at which sunlight irradiates the interior of the light head 1; and the second included angle is an included angle at which the sunlight cannot irradiate the interior of the light head 1.

(11) The first included angle is greater than or equal to 90°, and the second included angle ranges from 0° to 45°.

(12) As shown in FIG. 4, the light avoiding system comprises a signal detector which is arranged inside the light body and used for detecting if the light body is power-on or not. The light avoiding system further comprises a solar panel 41 arranged on the light body. When the light body is detected in the power-on state, the control assembly controls the solar panel 41 not to work, and when the light body is detected in the power-off state, the control assembly controls the solar panel 41 to generate electricity, and the driving electric motor 5 uses electric energy to drive the light head 1 to rotate so that the light head 1 avoids sunlight.

(13) An accumulator 42 can be further provided inside the light body. When the light body is in the power-off state, the accumulator 42 provides electric energy for the light avoiding system.

(14) The light avoiding system further comprises a sunlight detector 16 for detecting sunlight.

(15) When the sunlight is detected, the signal detector of the light avoiding system will detectif the light body is power-on or not. Thus, when there is sunlight and the light body is in the power-off state, the main controller 4 will detect and calculate the included angle between the direction of the light head and the gravity direction, then adjust the included angle to be within the range of the second included angle so as to achieve light avoiding.

(16) Therefore, the specific light avoiding operations of the stage light described in this embodiment are as follows. When the signal detector detects that the light body is in the power-off state, the accumulator 42 provides power for the sunlight detector 16. Then, when the sunlight detector 16 detects that the light head 1 is at a position that the sunlight irradiates, the main controller controls the solar panel 41 to generate electricity to provide electric energy for the driving electric motor 5. At the same time, the main controller 4 calculates, according to the data of the gravity sensor, the included angle α between the gravity direction and the direction that the light head 1 faces. If a is greater than or equal to 90°, the control assembly controls the driving electric motor 5 to rotate the light head 1 to 0° to 45°, so that the sunlight cannot irradiate the interior of the light head 1, thereby protecting the internal electrical elements of the light head 1. In addition, the accumulator 42 continues to provide electric energy for the light body, and the above-mentioned operation will follow the change of the sunlight direction so as to achieve smart control.

The light avoiding system comprises a gravity sensor 3 for detecting the gravity direction of the stage light, and a main controller 4 for calculating an included angle α between the direction of the light head 1 of the stage light and the gravity direction. When α is within the range of a first included angle, the main controller 4 controls the driving electric motor 5 to drive the light head 1 to rotate, and adjusts the angle of α to be within the range of a second included angle, in which the first included angle is an included angle at which sunlight irradiates the interior of the light head 1; and the second included angle is an included angle at which the sunlight cannot irradiate the interior of the light head 1.

(30) The protection system further comprises a signal detector arranged inside the light body. When the signal detector detects that the light body is in the power-on state, the control assembly controls the solar panel 41 not to work; and when the signal detector detects that the light body is in the power-off state, the control assembly controls the solar panel 41 to generate electricity.

When there is no sunlight, the light shading assembly 13 does not need to work, and therefore no light irradiates the interior of the light head.

(42) In addition, a sunlight detector 16 may be further provided according to this embodiment, when the signal detector detects that the interior of the light body is in the power-off state, the accumulator 42 provides power for the light shading assembly 13 and the control assembly, and when the sunlight detector 16 detects that the light head 1 is at a position that the sunlight irradiates, the control assembly controls the light shading assembly 13 to work, so that the driving system drives the light shading plate to shade the light head 1, thereby achieving smart light avoiding.
