Abstract

An LED tubular lighting device and control device includes LEDs planted in a transparent tube and controllable via a controller to obtain multifarious light sources. The tubular lighting device includes LEDs soldered onto a circuit board in an equi-distant arrangement. The circuit board with the LEDs is secured in a boat-shaped receiving, heat-dissipating trough, which are disposed in a transparent tube having heat-dissipating holes in the bottom wall thereof and through holes in both ends thereof. The LED tubular lighting devices can be connected in series and controllable to produce changes in colors and luminosity.

Claims

1. An LED tubular light device and control device, comprising an LED tubular lighting device and a programmable control device, wherein said LED tubular light device includes:

a strip-shaped circuit board having a plurality of LED light bulbs equi-distantly disposed thereon, two ends of said circuit board being respectively provided with input and output terminals;

a plastic transparent tube having a bottom wall provided with heat-dissipating holes, and two ends pre-formed with through holes, closed by two end stoppers; and

,

a heat-dissipating trough being a semi-circular aluminum-extruded receiving, light-converging, heat-dissipating trough located in said plastic transparent tube, an upper side thereof having a groove receiving said circuit board holding said LED light bulbs, said groove being centrally provided with a longitudinal recess, a lower side of said heat-dissipating trough provided with heat-dissipating fins that follow a curvature of an inner surface of said plastic transparent tube, two ends of said groove provided with trough holes accommodating said input and output terminals to facilitate connection with a power source end, said circuit board together with said LED light bulbs being secured in position after being disposed in said trough.

2. The LED tubular lighting device and control device of claim 1, wherein a plurality of said LED tubular lighting devices are connected in series by connecting wires with connecting terminals.

3. The LED tubular lighting device and control device of claim 1, wherein said control device comprises a control device controlling serially connected LED tubular lighting devices via predetermined programs.
