[0035] like Figures 1 to 6 As shown, the utility model provides an LED polarized lamp, including a base 1, a light source assembly 2 and a mounting portion connected to the base 1, the base 1 includes a seat including a bottom plate, and a first vertical plate 11 and a second vertical plate 12 which are relatively arranged on opposite sides of the bottom plate and extend in the same manner, the first vertical plate 11, the second vertical plate 12 and the bottom plate form a mounting cavity 13, the light source assembly 2 is arranged in the mounting cavity 13, the first vertical plate 11 and the second vertical plate 12 have a height difference, and a light outlet 14 is formed at one end of the first vertical plate 11 and the second vertical plate 12 away from the bottom plate, so that the light source assembly 2 is installed in the mounting cavity 13 and irradiates light along the direction of the light outlet 14.

[0036] The utility model forms a single-sided oblique light outlet 14 through the height difference between the first vertical plate 11 and the second vertical plate 12, so that the light source assembly 2 installed in the installation cavity 13 irradiates light along the oblique light outlet 14; the direct-down light-emitting lamp in the prior art has a large light-emitting angle. When a person enters the light-emitting angle range of the lamp, the light will directly enter the human eye and produce glare; compared with the prior art, the single-sided oblique light outlet 14 in the present solution can make the light-emitting surface of the light source assembly 2 be installed in the direction relative to the person approaching, and the light-emitting angle is polarized to one side. The light emitted by the light source assembly 2 will not directly enter the human eye, but enter the human eye through diffuse reflection from the surface of the irradiated object, thereby solving the problem of glare caused by light directly entering the human eye.

[0037] The installation cavity 13 has openings on both sides, and the light source assembly 2 can be installed into the installation cavity 13 from both sides, and the light-emitting part of the light source assembly 2 is installed toward the light outlet 14 so that the light is radiated along the light outlet 14 .

[0038] Specifically, in the present embodiment, the light source assembly 2 includes a lamp board 21 and a plurality of LED lamps 22 arranged on the lamp board 21, each LED lamp 22 is covered with a polarizing lens 23, and by covering the LED lamp 22 with the polarizing lens 23, the light emitted by the LED lamp 22 is biased and irradiated along the light outlet 14, wherein each polarizing lens 23 is provided with three column feet 231, and each LED lamp 22 on the lamp board 21 is provided with three column foot mounting holes corresponding thereto, and the polarizing lens 23 is detachably connected to the lamp board 21 through the column feet 231 and the column foot mounting holes.

[0039] Of course, in one of the embodiments, only one large-volume LED lamp 22 may be provided on the lamp board 21 , and correspondingly, only one polarized lens 23 matching the large-volume LED lamp 22 needs to be provided on the lamp board 21 .

[0040] Alternatively, in another embodiment, a plurality of LED lamps 22 are disposed on the lamp board 21 , but only one large polarized lens 23 is disposed on the lamp board 21 to cover all the LED lamps 22 so as to change the light direction of the LED lamps 22 .

[0041] In order to facilitate the installation and replacement of the light board 21, the first vertical plate 11 and the second vertical plate 12 are respectively provided with a card slot on the side facing the installation cavity 3, and the two card slots cooperate to form a light board card slot 131 in the installation cavity 13, and the light board card slot 131 is arranged parallel to the light outlet 14. The light board card slot 131 is arranged in the installation cavity 13, so that the whole light board 21 can be conveniently fixed and installed in the installation cavity 13. In addition, the light board card slot 131 is arranged parallel to the light outlet 14, which can ensure that the whole light board 21 is installed to the installation cavity 13. When installed in the cavity 13, it is parallel to the light outlet 14 to ensure that the LED lamp 22 on the lamp board 21 is irradiated in the direction of the light outlet 14. At the same time, the lamp board slot 131 is opened along the two sides of the installation cavity 13 from left to right. The user can slide the lamp board 21 into the lamp board slot 131 from the left or right side, so that the entire lamp board 21 is installed in the installation cavity 13. The LED lamp 22 irradiates light along the light outlet 14 set obliquely on one side in the installation cavity 13, which is very convenient whether to install or replace the lamp board 21.

[0042] Among them, in order to prevent the light board 21 from falling out of the light board slot 131 during use or after installation, the openings on the left and right sides of the installation cavity 13 are equipped with limit baffles 15. The limit baffles 15 can block the entire opening and the notch of the light board slot 131 to prevent the light board 21 from falling out of the light board slot 131.

[0043] Specifically, the limit baffle 15 includes a locking piece 151, and the limit baffle 15 is detachably connected to the base 1 through the locking piece 151 so as to block the left and right openings of the installation cavity 13, wherein the locking piece 151 is a screw, and a threaded hole is provided on the base 1, and the two limit baffles 15 are fixedly connected to the base 1 through the cooperation of the screw and the threaded hole. When the user needs to replace or repair the lamp board 21, the connection between the limit baffle 15 and the base 1 can be cancelled by removing the screw, so that the lamp board 21 is not limited by the limit baffle 15, and the user can easily pull the lamp board 21 out of the lamp board 21 slot 131 to replace the new lamp board 21 or repair the old lamp board 21.

[0044] Specifically, the installation part includes a mounting rail 3, and a slide groove 16 is provided at the bottom of the base. The slide groove 16 is slidably connected to the mounting rail 3. The user first installs the mounting rail 3 to the position where the LED polarized light source assembly 2 needs to be installed, and slides the base 1 along the mounting rail 3 to the required position. The user can easily complete the assembly of the base 1 and the mounting rail 3, which is convenient for the later maintenance and replacement of the base 1; in this solution, in order to prevent the base 1 from falling off the mounting rail 3, a through hole is provided at a designated position of the mounting rail 3, and a matching through hole is also provided on the slide groove 16 of the base 1. When the base 1 slides to the designated position, the user can fix the base 1 at the designated position by screws to prevent the base 1 from sliding left and right or completely falling off the mounting rail 3.

[0045] Specifically, the base 1 also includes a light-transmitting cover 17, which is arranged at the light outlet 14 and connects the first vertical plate 11 and the second vertical plate 12. In the present embodiment, slots 18 are provided at both ends of the front sides of the first vertical plate 11 and the second vertical plate 12. The light-transmitting cover 17 can prevent debris or dust from entering the installation cavity 13 from the light outlet 14 and causing damage to the light source assembly 2. The two long sides of the light-transmitting cover 17 can be inserted into the slots 18 along the grooves of the two slots 18 to facilitate the installation of the light-transmitting cover 17. At the same time, the limiting baffle 15 can also limit the light-transmitting cover 17 to prevent the light-transmitting cover 17 from falling out of the slots 18.

[0046] In another embodiment, the light cover 17 is connected to the first vertical plate 11 and the second vertical plate 12 by means of screws and threaded holes. The light cover 17 is fixed to the first vertical plate 11 and the second vertical plate 12 by the cooperation of the screws and the threaded holes to protect the light source assembly 2 in the installation cavity 13.
