Fluorescent wheel fixing structure and laser projection device

Abstract

The invention discloses a fluorescent wheel fixing structure and a laser projection device, relates to the technical field of display, and can reduce the size of a fluorescent wheel, reduce the cost,reduce the noise and improve the user experience on the premise of ensuring the normal heat dissipation of the fluorescent wheel. The structure comprises a housing, an inner cavity of the housing is used for containing a fluorescent wheel, the fluorescent wheel comprises a wheel piece and a motor, the output end of the motor is fixed to the wheel piece, a motor heat dissipation plate is closely fixed to the side, away from the output end, of an outer shell of the motor, and the motor heat dissipation plate and the inner wall of the inner cavity are fixed in an attached mode so that the fluorescent wheel and the shell can be fixed. The structure is used for manufacturing the laser projection device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a fluorescent wheel fixing structure and a laser projection device. Background technique [0002] A laser projection device is a device that uses laser projection imaging, such as a laser projector, laser projection smart glasses, laser TV, etc. Laser TV is composed of a laser light source projector and a projection screen using reflective ultra-short-focus projection technology, and can display a good picture even in a high-brightness environment. Compared with LCD TVs, laser TVs have more vivid colors and higher brightness. Moreover, it also has inherent advantages in the manufacture of super large screens. Compared with LCD TVs of the same size, the laser light source has a longer service life and lower power consumption, which meets the needs of society for energy conservation and environmental protection. The fluorescent wheel is one of the essential components of the la...

Problems solved by technology

However, in the solution of the prior art, the structure of the side wall of the light source housing 04 and the adapter bracket 03 will hinder the airflow generated by the rotation of the fluorescent wheel 01, which is not conducive to the heat dissipation of the fluorescent wheel 01 through the airflow of its own rotation. Moreover, the motor 012 generates The heat needs to be transferred to the adapter bracket 03 through the heat dissipation aluminum plate 013, and then transferred to the light source housing 04 by the adapter bracket 03 to dissipate heat. The heat propagation path is long and the heat dissipation effect is not good.

Therefore, the fluorescent wheel 01 needs to be set to a relatively large size (generally more than 65 mm in diameter) to meet the heat dissipation requirements, thereby making the light source module and the whole machine bulky and costly

In addition, since the fluorescent wheel 01 of the prior art is fixed to the light source housing 04 through the adapter bracket 03, during the rotation of the fluorescent wheel 01, on the one hand, the fixing accuracy of the adapter bracket 03 and the light source housing 04 is low, and the adapter bracket 03 will vibrate, which will generate noise; on the other hand, the structure of the adapter bracket 03 will hinder the airflow generated by the rotation of the fluorescent wheel 01, and will also generate noise, which will affect the user experience
