Embodiment
Embodiment 1
Refering to shown in Fig. 1 to Fig. 4, a kind of area source light-guiding shade of the invention, including body 1, the body 1 is by ring
The connecting portion 2 of shape and the light guide section 3 of flare structure form, and connecting portion 2 is set in outside area source periphery；The light guide section
Angle α between 3 inwalls and vertical plane is 10 °~45 °, and the height h of the light guide section 3 is 20~100mm.In the present embodiment
In, the inner surface of light guide section 3 is provided with reflective electrodeposited coating 4, light is reflected and is opened from light guide section 3 by reflective electrodeposited coating
Oral area projects.
Meanwhile the safeguard structure 6 that covering opening portion is used for water proof and dust proof is provided with the opening portion of light guide section 3.The protection knot
Structure 6 is open 9 groups of the first sealing ring 7, transparent prevention plate 8 and the hold-down ring of end surface by being sequentially arranged light guide section 3 from the inside to the outside
Into；The first positioning strip 7a is provided with the first sealing ring 7 end face relative with light guide section 3, is led corresponding to the first positioning strip 7a
Light portion 3 is provided with the mounting groove 3a being adapted with the first positioning strip 7a；The hold-down ring 9 is fixed by screw and light guide section 3 to be connected
Connect.Transparent prevention plate can preferably use safety glass or transparent acrylic.
The second sealing ring 10 is folded between the end face of connecting portion 2 and outside mounting surface, in the second sealing ring 10 with being connected
The relative end face in portion 2 is provided with the second positioning strip 10a, is being provided with and second on the end face of connecting portion 2 corresponding to the second positioning strip 10a
Locating slot 2a adaptable positioning strip 10a.In order to facilitate the connection between area source and external drive, in the side of connecting portion 2
Wall is provided with cable-through hole 2b, and WATERPROOF PACKING GLAND is connected with cable-through hole.
Further, install for convenience, installation counterbore 3b is provided with light guide section 3, light guide section 3 passes through peace by screw
Dress counterbore 3b is connected with external substrate.
In use, the light-guiding shade of the present invention is arranged on by area source periphery by connecting portion, according to irradiation distance need
Will, it can select to install light source diffusion plate additional inside light-guiding shade.
Embodiment 2
As shown in fig.5, a kind of combined light source disperser of the present invention, its structure is substantially the same manner as Example 1, no
