Benefits of technology

The invention improves the heat dissipation of LED devices, keeping them brighter and performing better for longer periods of time. This makes them less susceptible to brightness attenuation. In the same size of aquarium, the invention makes it necessary to increase the outer diameter or length of the lighting device in order to enhance the brightness. This makes the invention highly competitive.

Problems solved by technology

As lighting devices for underwater applications are to be turned on for a long period of time, they commonly use LED components for giving off light, saving the consumption of power supply.
However, using a LED light device requires quick heat dissipation, avoiding attenuation of LED brightness.
Conventional LED submarine lighting devices may not provide a heat-dissipation device.
Even a LED submarine lighting device is equipped with a heat-dissipation device, the heat dissipation effect is still not optimal.
After a long use of a conventional LED submarine lighting device, the problem of attenuation of LED brightness will occur.

Embodiment Construction

[0016]Referring to FIG. 1, a LED submarine light 100 in accordance with the present invention is shown. The LED submarine light 100 comprises a light-transmissive lamp tube 10, a LED substrate 20, a heat conducting bar 30, a front end cap 40 and a rear end cap 50.

[0017]The light-transmissive lamp tube 10 can be a plastic tube, comprising opposing front-end opening 11 and rear-end opening 12, and two longitudinal locating grooves 13 symmetrically located on the inside wall thereof at two opposite lateral sides. The LED substrate 20 is an aluminum clad circuit board fastened to the longitudinal locating grooves 13 in the light-transmissive lamp tube 10. Further, the LED substrate 20 has a plurality of LED devices 21 installed in the top surface thereof.

[0018]The main feature of the present invention is the arrangement of the heat conducting bar 30 in the light-transmissive lamp tube 10. As shown in FIG. 4, the heat conducting bar 30 is mounted in the light-transmissive lamp tube 10 be...

Abstract

A LED submarine lighting device includes a light-transmissive lamp tube, a LED substrate mounted inside the light-transmissive lamp and carrying a plurality of LED devices in the top surface thereof for giving off light, a heat conducting bar mounted in the light-transmissive lamp tube and stopped between the bottom surface of the LED substrate and the inside wall of the light-transmissive lamp tube for quick dissipation of waste heat from the LED devices to avoid the serious problem in brightness attenuation, and two end caps respectively fastened to opposing front and rear ends of the light-transmissive lamp tube in a water-tight manner.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to LED lighting devices and more particularly, to a LED submarine lighting device for underwater application, for example, for use in an aquarium, which is equipped with a heat conducting bar for quick dissipation of waste heat.[0003]2. Description of the Related Art[0004]For the advantage of energy saving and under the demand for carbon reduction, LED lighting industry has become a new generation of the mainstream market.[0005]In an aquarium or ornamental water eco system, a submarine lighting device may be installed to provide illumination and decoration functions. As lighting devices for underwater applications are to be turned on for a long period of time, they commonly use LED components for giving off light, saving the consumption of power supply. However, using a LED light device requires quick heat dissipation, avoiding attenuation of LED brightness. Conventional LED submarine light...
