On the other hand, for different lamp structure designs, it is only necessary to install a rotating light shade adjusting member 300 on the light outlet side of the light source module 200 to adjust the light spot size, that is, the adaptability is higher.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the rotating light-wave adjustment member 300 includes a first fixing ring 310, a second fixing ring 320 and a plurality of light-wave plates 330.

Each of the light-wave plates 330 is mounted on the second fixing ring 320. The plurality of light-wave plates 330 together form the light outlet 300a. It can be understood that the plurality of light-wave plates 330 are mounted on the second fixing ring 320. The first fixing ring 310 is connected to the housing 100. When the second fixing ring 320 rotates relative to the first fixing ring 310, the plurality of light-wave plates 330 move together with the second fixing ring 320 to adjust the size of the light outlet 300a, thereby adjusting the size of the light spot.

[0043] like Figure 3 As shown, in one embodiment, each of the light shielding sheets 330 is in an arc shape. In this embodiment, when the second fixing ring 320 rotates relative to the first fixing ring 310, the plurality of arc-shaped light shielding sheets 330 rotate in the same direction, thereby adjusting the size of the light outlet 300a.

In this embodiment, the fixing member 340 is a stop screw or a pin, and one end of the fixing member 340 is fixed to the first fixing ring 310 after passing through the rotation groove 321 and the fixing hole 311, and the other end of the fixing member 340 is located in the rotation groove 321 and is slidably connected with the second fixing ring 320, so that the first fixing ring 310 and the second fixing ring 320 can rotate relative to each other.

[0045] like Figure 3 As shown, in one embodiment, the number of the fixing members 340 is multiple, the number of the fixing holes 311 and the number of the rotation slots 321 are both multiple, and each of the fixing members 340 is correspondingly penetrated through the rotation slots 321 and the fixing holes 311. It can be understood that the multiple fixing members 340 make the fixing effect of the first fixing ring 310 and the second fixing ring 320 better, and at the same time make the relative rotation of the first fixing ring 310 and the second fixing ring 320 more convenient and accurate.

[0046] like Figure 3 As shown, in one embodiment, each of the light-wave plate 330 is provided with a first boss 331 and a second boss (not shown) on both sides, the second fixing ring 320 is provided with a plurality of fixing grooves 322, each of the first bosses 331 is correspondingly embedded in the fixing groove 322, so that the plurality of light-wave plates 330 are all engaged with the first fixing ring 310, the first fixing ring 310 is provided with a plurality of sliding grooves 312, each of the second bosses is located in the corresponding sliding groove 312.

[0047] like Figure 6 As shown, in one embodiment, the housing 100 includes a heat dissipation shell 110, a light source fixing ring 120 and a surface shell 130, the heat dissipation shell 110, the light source fixing ring 120 and the surface shell 130 are connected in sequence, the light source module 200 is installed in the light source fixing ring 120, and the first fixing ring 310 is connected to the light source fixing ring 120. It can be understood that the heat dissipation shell 110, the light source fixing ring 120 and the surface shell 130 are connected in sequence, the light source module 200 is installed in the light source fixing ring 120, and the heat generated by the light source module 200 when working is transferred to the heat dissipation shell 110, so that the temperature in the light source module 200 is kept within a certain range, avoiding the problem of damage to parts due to excessive temperature. Further, the first fixing ring 310 is installed in the light source fixing ring 120, and when the size of the light outlet 300a needs to be adjusted, the second fixing ring 320 is manually inserted into the surface shell 130 to rotate, thereby adjusting the size of the light outlet 300a.

[0048] like Figure 6As shown, in one embodiment, the projection type lighting device 10 further includes an anti-glare cover 400, the anti-glare cover 400 is connected to the face shell 130, and the anti-glare cover 400 is located on the side of the rotating light beam adjustment member 300 away from the light source module 200. It can be understood that the light from the light source module 200 enters the anti-glare cover 400 after passing through the light outlet 300a, so that the glare value of the light after passing through the anti-glare cover 400 is low.

[0049] like Figure 6 As shown, in one embodiment, a clamping column 131 is provided on the outer side of the face shell 130. It can be understood that the clamping column 131 on the outer side of the face shell 130 is used to clamp into the installation groove of the building body so that the projection type lighting device 10 is fixed on the building body.

[0050] It should be noted that the rotating light adjustment member 300 can be detachably installed in the housing 100, that is, the rotating light adjustment member 300 can be used in different types of projection lamps, such as embedded spotlights, track spotlights, ceiling spotlights and other lamps.

Compared with the design of telescopic adjustment, the structure of this application is more compact, and the rotating light shade adjusting member 300 occupies less space. On the other hand, for different lamp structure designs, it is only necessary to install a rotating light shade adjusting member 300 on the light outlet side of the light source module 200 to adjust the light spot size, that is, the adaptability is higher.

[0054] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent.
