[0061] As shown in FIG. 1, a stage light free from damage of sunlight comprises a light body and a control assembly, and further comprises a light avoiding system. 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.

[0062] As shown in FIG. 2, the light body comprises a light head 1, a light base 2, and a driving electric motor 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 to rotate so that the light head 1 avoids sunlight.

[0063] 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 between the direction of the light head 1 of the stage light and the gravity direction. When is within the range of a first included angle, the main controller 4 controls the driving electric motor to drive the light head 1 to rotate, and adjusts the angle of a 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.

[0064] The first included angle is greater than or equal to 90, and the second included angle ranges from 0 to 45.

[0065] 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 arranged on the light body. When the light body is detected in the power-on state, the control assembly controls the solar panel not to work, and when the light body is detected in the power-off state, the control assembly controls the solar panel to generate electricity, and the driving electric motor uses electric energy to drive the light head 1 to rotate so that the light head 1 avoids sunlight.

[0066] An accumulator can be further provided inside the light body. When the light body is in the power-off state, the accumulator provides electric energy for the light avoiding system.

[0067] The light avoiding system further comprises a sunlight detector for detecting sunlight.

[0068] 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. 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 provides power for the sunlight detector. Then, when the sunlight detector detects that the light head 1 is at a position that the sunlight irradiates, the main controller controls the solar panel to generate electricity to provide electric energy for the driving electric motor. At the same time, the main controller 4 calculates, according to the data of the gravity sensor, the included angle 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 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 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.

Embodiment 2

[0069] In this embodiment, as shown in FIG. 2, a stage light free from damage of sunlight comprises a light head 1, a light base 2, and a driving electric motor. With reference to FIG. 3, the light head 1 and the light base 2 are in rotary connection by means of the driving electric motor. 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 between the direction of the light head 1 of the stage light and the gravity direction. When is within the range of a first included angle, the main controller 4 controls the driving electric motor to drive the light head 1 to rotate, and adjusts the angle of a 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.

[0070] The first included angle is greater than or equal to 90, and the second included angle ranges from 0 to 45.

[0071] As shown in conjunction with FIG. 5, the light base 2 comprises a base 21 and a light arm 22. The light head 1 is rotatably connected to the light arm 22.

[0075] According to the present embodiment, as shown in FIG. 5, the light head 1 comprise a cylindrical optical element portion 11 and a circular truncated cone-shaped lens portion 12. The cylindrical optical element portion 11 and the lens portion 12 are detachably connected through, for example, threadably rotatory connection or snap-fit connection. The lens portion 12 is provided with a lens.

[0076] The light base 2 is further provided with an accumulator. When the stage light stops working, the accumulator provides electric energy for the main controller 4, the driving electric motor and the gravity sensor 3.

[0077] According to the present embodiment, the stage light is also provided with a solar panel. When the stage light stops working, but within sunlight, the solar panel will absorb solar energy to generate electricity and provides electric energy for the main controller 4, the driving electric motor and the gravity sensor.

[0078] The protection apparatus further comprises a sunlight detector for detecting sunlight.

[0079] Therefore, the specific light avoiding operations of the stage light described in this embodiment are as follows. When the light body is in the power-off state, the accumulator provides power for the sunlight detector. Then, when the sunlight detector detects that the light head 1 is at a position that the sunlight irradiates, the main controller 4 calculates, according to the data of the gravity sensor, an included angle 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 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 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.

[0082] 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 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 to generate electricity.

[0083] The solar panel is arranged on one side of the light body.

[0084] The light body comprises a light base 2 and a light head 1 rotatably connected to the light base 2, the control assembly is arranged in the light base 2, the light head 1 comprises a light source and a light emitting lens.

[0085] The driving system comprises a driving electric motor, and the driving electric motor is arranged at the junction between the light base 2 and the light head 1.

[0086] Therefore, the specific light avoiding operations of the stage light in this embodiment are as follows. When the detector detects that the interior of the light body is in the power-off state, the control assembly controls the solar panel to work. When there is sunlight outside, the solar panel provides electric energy for the driving electric motor, so that the driving electric motor drives the light head 1 to rotate, thereby achieving smart light avoiding. When there is no sunlight, the solar panel cannot work, which also proves that there is no sunlight in the current environment, and therefore no light irradiates the interior of the light head 1.

[0088] The light emitting end of the light body is provided with a fixed lens and a magnifying lens, and the light shading assembly is arranged between the fixed lens and the magnifying lens.

[0089] The stage light 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 light shading assembly to open; and when the signal detector detects that the light body is in the power-off state, the control assembly controls the light shading assembly to close so as to shade the light emitting end.

[0092] The light shading plate is made of aluminum alloy, magnesium alloy or plastic.

[0093] Therefore, the specific light avoiding operations of the stage light in this embodiment are as follows. When the signal detector detects that the light body is in the power-off state, the accumulator provides power for the light shading assembly and the control assembly, and the control assembly controls the light shading assembly to work, so that the driving system drives the light shading plate to shade the light head 1, thereby achieving smart light avoiding. When there is no sunlight, the light shading assembly does not need to work, and therefore no light irradiates the interior of the light head.

[0094] In addition, a sunlight detector 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 provides power for the light shading assembly and the control assembly, and when the sunlight detector detects that the light head 1 is at a position that the sunlight irradiates, the control assembly controls the light shading assembly to work, so that the driving system drives the light shading plate to shade the light head 1, thereby achieving smart light avoiding. When there is no sunlight, the light shading assembly does not need to work, and therefore no light irradiates the interior of the light head 1.
