The invention belongs to the technical field of light emitting, and particularly relates to a side-in type backlight module which comprises a circuit substrate, lamp panels, a light emitting chip, a light uniformizing piece and a light uniformizing unit, the lamp panels are arranged on one side of the circuit substrate and are perpendicular to the circuit substrate, a plurality of grids are defined by the multiple lamp panels on the surface of the circuit substrate, and the light emitting chip is arranged on the light uniformizing piece. One surface of the circuit substrate close to the lamp panel is coated with a reflecting layer; the light-emitting chips are arranged on the surface of the lamp panel, at least one light-emitting chip is arranged in each grid, and the circuit substrate and the light-emitting chips are electrically connected through the lamp panel; the grids are wrapped and clamped by the dodging sheet and the circuit substrate, a plurality of dodging units are arranged on the side, close to the circuit substrate, of the dodging sheet, the dodging units and the grids are embedded into the grids in a one-to-one correspondence mode, and the dodging sheet is positioned. The backlight module has the effect that positioning between the dodging sheet and the backlight source is more stable and accurate.

The application discloses a light-emitting substrate, a backlight module and a display device, and belongs to the technical field of display. The light-emitting substrate provided by the application comprises a back plate, a driving circuit layer and a plurality of light-emitting units. The light-emitting unit comprises a reflecting layer, a paving layer and a light-emitting chip. Since the light-emitting surface of the light-emitting chip faces the reflecting layer, the light emitted by the light-emitting chip is first transmitted to one side of the back plate, and then is reflected by the reflecting layer arranged on the inner wall of the counterbore on the back plate, so that the path of the light emitted by the light-emitting chip is prolonged. In this way, after the light-emitting substrate is integrated in the backlight module, the distance between the light-emitting substrate and the diffusion plate in the backlight module does not need to be increased, the backlight module can have a better light mixing effect, and the overall thickness of the backlight module is relatively low.

This utility model relates to the technical field of polarized wall washer lenses, and discloses a light-mixing polarized wall washer lens, including a lens body. The lens body includes a freeform surface, a polarizing region, a reflective surface, a first polarizing surface, a second polarizing surface, and a refractive surface. The reflective surface is used to reflect light to the polarizing region, and the refractive surface is used to refract light to the polarizing region or the freeform surface. The first and second polarizing surfaces are respectively used to refract light to the freeform surface, and the refraction angles of the first and second polarizing surfaces are not aligned. The polarizing region and the freeform surface are respectively used to converge light and project it outward to form a light spot. With the combined effect of the polarizing region and the freeform surface, it has a greater light output effect and helps to increase the light output distance, meeting the needs of wall washer lights. Furthermore, under the action of the first and second polarizing surfaces, the light mixing effect is enhanced, thereby improving the presentation effect of the light spot.
