Abstract
The present invention relates to a lamp system including a digital micro-mirror device (DMD) module, and more particularly, to a system and method for improving life characteristics of a DMD module. A DMD lamp and a method of controlling a DMD lamp of the present invention may improve a life of a DMD module by measuring a temperature of the DMD module in real time and controlling operations of the DMD module and a light source when the temperature of the DMD module rises above a certain temperature, and improve the life of the DMD module by adjusting a ratio of an ON mode/OFF mode of the DMD module to the same ratio and automatically compensating for the insufficient amount of light to reduce the consumption of an angle adjusting unit of a mirror to a minimum while maintaining the output amount of light.
