Embodiment 1）

[0049] See figure 1 and Figure 6 , The floodlight of the present invention includes a lamp body 100 , a connecting assembly 5 , a bracket 6 , a laser emitter 7 and a connecting frame 8 .

[0050] See figure 1 and Figure 6 , the lamp body 100 includes a lampshade 1 , a lamp housing 2 , a wiring cap 4 , an LED lamp board 9 , a lens assembly 10 and a power cord 11 .

[0051] See figure 2 , Figure 5 and Figure 6 , The lampshade 1 includes a stainless steel flange 1-1 and a glass 1-2 made of stainless steel. The stainless steel flange 1-1 of this embodiment adopts 316 stainless steel. The glass 1-2 is airtight and fixedly arranged in the stainless steel flange 1-1. When making, first process the glass into the shape and size corresponding to the stainless steel flange, then put it into the stainless steel flange, and place it in the corresponding graphite mold together, and then enter the electric furnace oven for heating, using nitrogen gas Protection, at a temperatu...

Embodiment 2）

[0063] See Figure 9 and Figure 10 , the rest of this embodiment is the same as that of Embodiment 1, except that the connection assembly 5 includes a first connection ring 5-1 and an adjustment plate 5-4.

[0064] The stainless steel sealing plate 4-1 of the wiring cap 4 is provided with a circular through hole 4-1-1. The glue filling part 4-2 is a cylindrical shell-shaped part with an opening facing to the right made of stainless steel, and its shape corresponds to the circular through hole 4-1-1. The left side of the glue filling part 4-2 is provided with a wire hole 4-2-1 running through it. The glue potting part 4-2 is laser welded from left to right, sealed and fixedly connected to the circular through hole 4-1-1 of the stainless steel sealing plate 4-1.

[0065] The first connecting ring 5-1 is an integral piece made of steel, and the upper part of the outer circumference of the first connecting ring 5-1 is provided with a radially outward protruding part, and the p...

Embodiment 3）

[0068] This embodiment is the same as Embodiment 1, and the difference is that the lamp housing 2 of this embodiment is one piece, without the front lamp housing 2-1, and the left and right length of the original rear lamp housing 2-2 is extended It is the sum of the left and right lengths of the original front lamp housing 2-1 and the rear lamp housing 2-2.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a floodlight. Background technique [0002] Flood lights make the illuminance on the designated illuminated surface higher than that of the surrounding environment. Generally, it can aim in the required direction and requires a structure that is not affected by climatic conditions. It is mainly used for large-area operation sites, mines, building outlines, stadiums, overpasses, parks and flower beds, etc. Therefore, almost all outdoor use Large-area lighting fixtures can be regarded as floodlights. The output beam angle of the floodlight is wide or narrow, and the range of variation is between 5° and 110°. At present, more and more cities have begun to install corresponding floodlights for night lighting in blocks with relatively concentrated high-rise buildings, bustling commercial districts, or urban landmark buildings, which play a role in lighting and beautifying the city ...
