This utility model relates to the technical field of drainage devices for steel structure factory buildings, and particularly to a roof drainage system with a self-cleaning function, comprising: a gutter; a first filter plate installed in the gutter for intercepting debris; wherein the first filter plate divides the gutter vertically along the direction of gravity into: a receiving trough above the first filter plate and an external discharge chamber below the first filter plate; several filter holes opened on the first filter plate, one end connected to the receiving trough and the other end connected to the external discharge chamber; a first drain pipe, one end connected to the external discharge chamber and the other end extending towards the ground; a self-cleaning component for conveying debris in the receiving trough along the length of the gutter; a receiving box installed on the wall at one end of the gutter and connected to the receiving trough for receiving debris; by setting the first filter plate, debris and rainwater can be separated, preventing debris from clogging the first drain pipe, and debris on the first filter plate can be periodically removed to ensure the normal filtering operation of the first filter plate.

This utility model relates to the field of LED linear light technology, and more particularly to an LED linear light that solves the problems of glare and shadow formation in existing LED linear lights, resulting in poor performance. An LED linear light includes a light board with several bulbs electrically connected to its bottom. The surface of the light board has a housing, inside which two U-shaped clamping plates are fixedly connected. The light board is slidably connected between the two clamping plates. Inside the housing, several vertically distributed anti-drop blocks are fixedly connected. Two support plates are slidably connected between the tops of two anti-drop blocks at the same height. Several diffuser blocks are fixedly connected between the two support plates. This utility model prevents glare and shadows, ensuring performance. Heat is conducted to the housing and heat sink via a thermal pad for heat dissipation, ensuring stable operation of the light board.

This invention provides a pixel array that can be illuminated by backlighting from a backlight source. The backlight source may include a two-dimensional array of light-emitting diodes (LEDs), with each LED placed in a corresponding cell. Different LEDs may have unique brightness levels based on the content of a given display frame. A driver integrated circuit (IC) can control one or more associated LEDs to have a desired brightness level. The driver IC may be formed in the active region of the backlight source. The driver IC may be arranged together in a daisy-chain group. Digital signals (including information such as addressing information) can be propagated through this group of driver ICs. To manage the thermal performance of the backlight source, the backlight source may include a thermally conductive layer and / or a heat sink structure. To improve the efficiency of the backlight source, the backlight source may include one or more reflective layers.
