For achieving the above object, this utility model is employed the following technical solutions：

A kind of LED open airs laser projecting lamp, by light cover, heat radiation type lamp body, projection convex lenss and replaceable film group Into the heat radiation type lamp body outer surface is uniformly distributed the radiating scale of some circles, and the heat radiation type lamp body wherein side is with radiating Radiator fan is installed, the heat radiation type lamp body opposite side relative with the heat dissipation box position arranges film window and fix in box and the box Cover and the window is connected with the replaceable film inside lamp body；The heat radiation type lamp body external port carries light cover, the lamp One layer of laser window is set between lid and heat radiation type lamp body port；Heat radiation type lamp body inside fixed installation relay lens frame and Some projection convex lenss of this relay lens frame surface annular spread, fixedly mount in the inner chamber below this relay lens frame and carry The lamp plate of LED lamp bead, the lamp body inner chamber between LED lamp bead therein and relay lens frame fixedly mounts replaceable film；Institute State relay lens frame to be made up of pillar and upper and lower two circular base plates, low bottom-disc therein is connected with lamp plate, upper bottom therein Disk is adjacent with laser window, and pillar two ends therein are separately fixed in the location hole on chassis.

Correspondingly, the laser window outward flange sets up a circle waterproof apron.

It is described projection convex lenss quantity be set to six or more than, less than six.

LED lamp bead inside heat radiation type lamp body constitutes laser projection system with replaceable film.

LED described in the utility model open air laser projecting lamp has the beneficial effect that：

(1) traditional projecting lamp internal structure has been simplified, and easy to use, simple structure, manufacturing cost are relatively low；

(2) it is connected with replaceable film by arranging film window fixation lid, is easy to change film, Neng Gouman at any time Use demand under sufficient different scenes；

(3) the LED lamp bead inside heat radiation type lamp body constitutes laser projection system with replaceable film, changes traditional Laser mode.
