The invention discloses a projection lamp, which comprises a lamp body, a connecting
assembly and a support, wherein the lamp body is fixedly arranged on the support through the connecting
assembly. The projection lamp is characterized by also comprising a
laser transmitter and a connecting rack. The
laser transmitter is detachably fixed on the lamp body and the connecting
assembly through the connecting rack; and an
optical axis of the
laser transmitter is mutually parallel to an
optical axis of the projection lamp. The lamp body comprises a lamp cover, a lamp housing, a connection cap, an LED (Light-emitting
Diode) lamp panel, a lens assembly and a power line. The lamp cover comprises a stainless steel
flange and glass. The connection cap, the lamp housing and the stainless steel
flange of the lamp cover are sequentially sealed, fixed and connected into a whole in a
laser bonding way. The
LED lamp panel and the lens assembly are sequentially fixed in the lamp housing from left to right. One end of the power line is electrically connected with a corresponding
electrode of the
LED lamp panel, and the other end of the power line is located outside the connection cap. Pouring
sealant is filled in the connection cap, sealing and
waterproofing processing is carried out, and the part of the power line located in the connection cap is wrapped by the pouring
sealant in a sealing and
waterproofing way.
