Abstract

The utility model discloses a DLP (Digital Light Processing) module and a DLP projection headlight, the DLP module comprises a control panel, a light source module and a light source module, the heat dissipation assembly comprises at least two heat dissipation parts and is mounted on the back of the control panel; and the lens assembly is arranged at the front part of the control panel and is connected with the control panel through an adjusting structure so as to realize the adjustable distance between the lens assembly and the control panel. The adjusting structure comprises a sliding groove formed in the lens base and a mounting hole formed in the lens support, a fastener penetrates through the mounting hole to move in the sliding groove, and the fastener is limited after being locked. The sliding groove is in a partial spiral shape so that the lens assembly can rotationally adjust the distance between the lens assembly and the control panel. Compared with the prior art, the LED lamp has the advantages that the LED lamp is simple in structure and high in heat dissipation effect, adjustment is achieved through the dimming screw, and personalized setting is achieved.
