The invention provides a laser projection device. The laser projection device includes an upper heat radiation device and a lower enclosed optomechanical device, wherein the heat radiation device includes an upper heat radiator and a water cooling row of a laser assembly, the enclosed optomechanical device includes a laser assembly, a control circuit and a lower heat radiation device, the laser assembly includes an internal heat radiation device, the internal heat radiation device is connected with the water cooling row of the laser assembly, and the lower heat radiation device is connected with the upper heat radiation device. The laser projection device is advantaged in that all important components such as the laser assembly and the control circuit are completely sealed in the enclosedoptomechanical device, the sealed cavity is radiated by the external heat radiation device connected with internal heat generating component, so waterproofing, dustproof and heat radiation purposes ofthe laser projection device are achieved, the very good dust and water resistance effect is achieved, for example, the waterproof and dustproof rating can reach IP66, slowing down brightness attenuation of the machine is facilitated, and the service life is prolonged.
Description
technical field [0001] The invention relates to a laser projection device, in particular to a waterproof and dustproof laser projection device capable of good heat dissipation. Background technique [0002] The dust and temperature in the environment where the projection display equipment in the laser projection device is located have a great impact on the life of the laser projection device. At present, most of the laser projectors of various manufacturers on the market use such as figure 1 The open heat dissipation method shown: that is, the optical machine is sealed, and the air inlet is equipped with a filter to prevent heat and dust from the device. This structure is relatively simple and convenient. The air duct is formed inside the air inlet and outlet to heat the device. The cooling effect is better. Therefore, the heat dissipation scheme of ordinary laser projectors is widely used because of its simple design structure, good heat dissipation effect and low price. ...
