Abstract: An LED display device includes an installing pillar, a first fixing plate, an enclosure module, an LED display screen module and a first connection member, the enclosure module includes a front surface for display and a rear surface opposite to the front surface, the installing pillar is positioned on the rear surface of the enclosure module, the first fixing plate closely contacts the installing pillar, the first fixing plate defines a first fixing hole, the first connection member extends through the first fixing hole from the rear surface of the enclosure module and connects with the enclosure module, thereby clamping and securing the installing pillar between the first fixing plate and the enclosure module, and the enclosure module is fixed to the installing pillar via the first fixing plate and the first connection member, the LED display screen module is assembled to the front surface of the enclosure module.

Abstract: An LED ceiling lamp includes a base, a lampshade, an LED component, and a power supply assembly. The base includes a main body and a receiving box having an opening, the main body defines a through hole, an opening end of the receiving box disposes on an edge of the through hole on the main body. The lampshade is shielded on the base, the receiving box is received in a cavity enclosed by the lampshade and the base. The LED component is disposed on the base and received in the cavity. The power supply assembly is received in the receiving box and located outside the cavity, the receiving box defines a wire hole, the power supply assembly has a wire, the wire extends through the wire hole, the power supply assembly is electrically connected to the LED component through the wire.

Abstract: A small-spacing LED screen is provided, comprising a bottom case, an HUB board arranged on one side of the bottom case, and a small module arranged on the other side and electrically connected with the HUB board. The small module includes a module main body and a drive control unit which is electrically connected with the module main body to drive and control the module main body. An adaptor plate is also arranged between the small module and the HUB board. The HUB board is electrically connected with the adaptor plate. The drive control unit is arranged on the adaptor plate. The LED screen has the smallest spacing, and the reject ratio of the small module is greatly reduced.

Abstract: Disclosed is an LED ceiling lamp, comprising a base, a lampshade, an LED assembly and a protective cover, wherein the lampshade is permanently connected with the base to form an enclosed space where the LED assembly and the protective cover are accommodated; the LED assembly includes a lamp panel and several LED lamp beads arranged on the lamp panel, and the side of the lamp panel away from the LED lamp beads is fixed on the base; the protective cover includes a cover body, arranged on the lamp panel and connected with the base, and several lenses arranged in the cover body with one lens shade on each LED lamp bead. For the LED ceiling lamp above, refraction of the light from the LED lamp beads by the lens shades provides better light distribution and uniform luminance, making the light more uniform and softer and producing fewer dark regions.

Abstract: An LED display mask and an LED display are provided. The LED display includes at least two first frame strips and at least two second frame strips which are orthogonal to each other and form a rectangular mesh body. The rectangular mesh body is fixed to a bottom case of an LED module and has at least two unclosed sides. The tail ends of the frame strips orthogonal to the unclosed sides exceed the outside frame strips parallel to the unclosed sides. The LED display mask and the LED display solve the problem that the existing adjacent masks on the LED display bulge at the junctions because of unmatched dimensions or thermal expansion, resulting in black shadows and dark areas on the display. With the present invention the excessive parts can be easily cut when adjacent masks extend mutually to form bulges without affecting the characteristics of the display.

Abstract: An LED display screen case includes a module, a HUB plate, a case frame, a power supply and a receiving card. One side of the HUB plate is connected with the module by a plug A and an interface A in a plugging mode. The other side of the HUB plate is connected with the receiving card by a plug B and an interface B in the plugging mode. A through hole is formed at a position corresponding to the plug B on the case frame. The plug B passes through the through hole. The receiving card and the HUB plate are connected by the plug B and the interface B in the plugging mode and fixed to the two sides of the case frame. This kind of connection type reduces the space inside the case for accommodating devices, and also ensures the good radiating effect of the case.

Abstract: A locking connection device, an LED box and an LED display screen are provided. The device includes a locking module and an inserting module. The locking module includes a hook and a bump matching with each other. The inserting module includes a fixing pin and a fixing hole matching with each other. The fixing pin and hook are fixed on a first base, and the bump and the fixing hole are fixed on a second base. The locking connection device further includes a driving module that propels the hook and the fixing pin to move synchronously. When the driving module finishes a travel, the hook and the bump are securely connected, and the fixing pin and the fixing hole are securely connected. Since the locking module according to the present invention locks the movement of the first base and the second base along the axial direction of the fixing pin and meanwhile the inserting module locks a circumferential movement of the fixing pin, the first base and the second base are securely fixed.
