Description

 Technical field

 Background technique

 As we all know, because of the need for stage effects, the stage light installation angle is 360. Any angle within the degree. Due to this indeterminate installation, the general stage lights are designed such that their cooling requirements do not depend on the installation position of the stage lights. This can lead to the situation where more unnecessary cooling energy is used for the cooling device, resulting in too low cooling efficiency and even reduced lifetime of the light source.

 Due to the rapid development of electronic integration technology, there are already integrated chips for position detectors on the market, which can be determined based on gravity relative to 3 The actual position of the orthogonal axes. These integrated chips currently have a wide range of applications, such as the LCD display orientation on the smartphone will automatically turn according to the user's situation.

In the existing stage lights, due to the large power of the light source, relatively large heat is usually generated. If the heat is not discharged in time, the internal flow field of the lamp will be uneven, and the internal stress of the light source will be too large, resulting in the foaming of the light source. Whitening and other consequences; therefore, the corresponding thermal system is generally equipped to heat and cool the light source.

When the stage light is used, such as a moving head light, the position of the lamp head and the light source changes in real time, and the working state and control of the existing thermal system are not adjusted according to the position of the stage light, so it is easy Excessive cooling energy or too little cooling energy will be generated, resulting in low cooling efficiency, which cannot effectively meet the heat dissipation requirements and affect the service life of the lamps.

 The application number is 201120574326.7 The Chinese invention patent discloses the 'mounting angle adjustment adaptive heat sink projector'. The patent adopts the following technical solution: 'The optical system is equipped with a gravity sensor chip and a CPU. Central controller and fan control chip, gravity sensor chip connected to CPU central controller, CPU A fan control chip is connected to the fan in the central controller, and the fan speed is controlled by the fan control chip; the gravity sensing chip transmits the installation angle signal to the CPU central controller, the CPU The central controller calculates the amount of heat required after the projector is installed, CPU A fan control chip is connected to the fan in the central controller, and the fan control chip is used to control the rotation speed of the fan, thereby completing heat dissipation processing at different installation angles. This technology can only adjust the heat dissipation during startup, and can not realize real-time monitoring and adjustment. Therefore, there are defects such as inability to adaptively adjust and heat control effect is not ideal. .
