LED lamp tube-shaped light equalizing device

Abstract

The invention relates to an LED lamp tube-shaped light equalizing device. The LED lamp tube-shaped light equalizing device comprises a lampshade, a lamp holder, a lamp panel, lamp beads, a main control board, a main board support, a PC transparent tube, a pore membrane, a light mixing membrane and a driver board; the lamp panel is fixed at the joint of the cylindrical lampshade and the lamp holder; the lamp beads include white lamp beads and RGB lamp beads, all of which are evenly fixed on the lamp panel; the main control board is mounted on the main board support at the top of the lampshade and connected with the lamp board by use of an FFC wire; the upper part of the PC transparent tube is clamped and fixed with a groove formed in the bottom of the main board support, while the lower part of the PC transparent tube is connected with the lamp panel to support up and down. The LED lamp tube-shaped light equalizing device is in a bottom light emitting form without light spot, and the brightness of the white light is uniform at the top and the bottom of the whole cylindrical lampshade; besides, the number of the used lamp beads is small so that the production cost can be greatly reduced; the LED lamp tube-shaped light equalizing device is low in power, energy-saving and environmental friendly, and meanwhile, capable of achieving optical effects that cannot be achieved in other light emitting manners.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a tube-shaped light equalizing device for LED lamps emitting light from the bottom. Background technique [0002] High-quality LED lighting requires that the mixed light of R, G, and B on the entire cylindrical lampshade must be very uniform, and color spots of different colors are not allowed on the lampshade, and inconsistent brightness from top to bottom is not allowed on the entire cylindrical lampshade. Condition. [0003] At present, there is no LED light equalizing device that can connect the top of the cylindrical lampshade to the bottom of the cylindrical lampshade through wires, and the LED light source is at the bottom of the cylindrical lampshade, so that the R, G, and B colored lights can be evenly mixed in the color gamut. , and at the same time make the brightness of the white light uniform on the top and bottom of the entire tubular lampshade, so that the li...

Problems solved by technology

However, the number of lamp beads used in the prior art is too large, 16 for white light, and 16 for R, G, and B integrated lamp beads. The cost of lamp beads is very high, and because each lamp board needs and drives The board is connected, so 8 pairs of connectors will be used, and the assembly process is also very complicated
