[0004] Wherein, when the laser projection device is started, the rotation speed value of the fan of the laser projection device is usually determined according to the external environment temperature, and the fan is started at this rotation speed value to dissipate heat inside the laser projection device. , the filter set at the air inlet and outlet of the laser projection equipment will accumulate dust, which will affect the ventilation effect of the laser projection equipment. Therefore, when the laser projection equipment is started, the fan speed value is only determined according to the external ambient temperature. The air volume provided by the rotation speed value cannot reach the air volume required for the laser projection equipment to dissipate heat at the external ambient temperature, and thus cannot meet the heat dissipation requirements of the laser projection equipment used for a long time

Embodiments of the present invention provide a heat dissipation control method and device for a laser projection device. The heat dissipation control method of the laser projection device of the present invention includes: obtaining the compensation value of the ambient temperature and the rotation speed of the fan when the laser projection device is started this time; determining the fan of the laser projection device according to the ambient temperature and the first preset rotation speed information The first rotational speed value of the fan of the laser projection device; the initial rotational speed value of the fan at this startup is determined according to the first rotational speed value of the fan of the laser projection device and the compensation value, and the initial rotational speed value is used as the current rotational speed value, and the The current rotational speed value controls the operation of the fan to dissipate heat from the laser projection device. The embodiments of the present invention can quickly meet the heat dissipation requirements of the laser projection device when it is started.
Description
technical field [0001] Embodiments of the present invention relate to electronic technology, and in particular to a method and device for controlling heat dissipation of a laser projection device. Background technique [0002] Laser projection equipment is a device that uses laser beams to transmit images, and is widely used in home theaters, business meetings, educational meetings and other fields. [0003] Since the laser projection equipment will generate heat during operation, at the same time, the temperature of the laser equipment will also be affected by the ambient temperature. If the external environment temperature is high, coupled with the heat generated by the operation of the laser projection equipment itself, it will cause the laser projection equipment to If the temperature of the laser projection device is too high, it will affect the operation ability of the laser projection device. Therefore, the laser projection device needs to actively dissipate heat. In...
