CN201184551Y - tube light - Google Patents

Abstract

The utility model relates to a tubing lamp. The tube lamp includes a light-transmissive tube and an end cap mounted at each end. Electrical contacts extend from each end cap, and a row of LEDs is attached to each end cap and receives power through the respective contacts. The LEDs are configured to emit light along the tube and onto the interior of the tube. Preferably, the tube is translucent so as to emit light and uniformly radiate the light around. The lamp has a size and shape that can be received in and adapted to a fixture designed for a standard form factor fluorescent tube.

Description

tube light

technical field

The utility model relates to lighting equipment. The present invention relates more precisely, but not exclusively, to tubular lighting with encapsulated LEDs.

Background technique

For many years, fluorescent tubes were used as an energy-efficient alternative to incandescent lighting. Modern high-brightness LEDs are even more energy efficient than fluorescent tubes, however, existing fluorescent fixtures are designed to accommodate fluorescent tubes in a variety of standard form factors. Some manufacturers offer LED replacement lamps in standard fluorescent tube form factors for easy retrofitting. Such replacement tubes are known to comprise an elongated planar circuit board extending longitudinally within a plastic tube and comprising an array of LEDs soldered on the circuit board, all facing towards the direction transverse to the longitudinal length of the tube. same direction.

Since the known luminaires were originally designed for use with fluorescent tubes which radiate light in all radial directions transverse to the longitudinal length of the fluorescent tube, the known structures described above do not produce the desired broad light scatter.

Another problem associated with known fluorescent tubes naturally concerns damage and disposal because of the fluorescent coating and mercury contained in the tube.

Utility model content

An object of the present invention is to overcome or substantially improve at least one of the above-mentioned disadvantages and/or more generally provide an improved LED tube light.

A kind of tube lamp is disclosed here, and it comprises:

Light-transmitting tube;

an end cap fitted to the end of the tube;

electrical contacts extending from the end cap; and

An LED, attached to the end cap, receives power through the contacts and is configured to emit light along the tube and onto the tube interior.

Preferably, the tube is cylindrical and has said end caps mounted on each end of the tube with the LED of each end cap pointing towards the other end cap.

Preferably, each end cap has a pair of said electrical contacts.

Preferably, each end cap comprises a row of LEDs, wherein each LED of the row of LEDs is configured to emit light along the tube to illuminate the tube interior.

Preferably, the light-transmissive tube is substantially transparent.

Optionally, the transparent tube is translucent.

Preferably, the light-transmissive tube is substantially transparent with a translucent coating on its inner and/or outer surface.

Preferably, the tube light is of a size and shape capable of being accommodated and adapted to a luminaire designed for a standard form factor fluorescent tube.

The present invention will advantageously provide an energy saving tube lamp with substantially omnidirectional light emission in standard fluorescent tube form factor.

Description of drawings

Now, with reference to accompanying drawing, describe preferred form of the utility model by way of example, wherein:

FIG. 1 is a schematic perspective view of an LED tube lamp;

Fig. 2 is a schematic side view of the LED tube lamp of Fig. 1; and

FIG. 3 is a schematic exploded side view for describing the LED tube light of FIGS. 1 and 2 .

Detailed ways

In the drawings, a tube light 10 manufactured in a standard fluorescent tube form factor for fitting into a standard light fixture is schematically illustrated. The tube light 10 comprises a light-transmitting tube 11, each end cap 12 having electrical contacts 13 protruding longitudinally therefrom for contacting corresponding contacts in the luminaire itself.

Typically, tube 11 is of plastic material or glass, and may be substantially transparent or translucent. The tube 11 may be a substantially transparent material with a translucent coating on its inner and/or outer surface.

LEDs 14 are mounted to each end cap 12 and face the longitudinal direction of the tube light 10. Typically, the LED 14 is a high brightness device capable of emitting a very bright and hardly divergent light that impinges on the inner surface of the plastic tube 11 causing the tube 11 to glow and thereby emit light in all radial directions.

Because the tube light 10 is intended to be installed in a standard high voltage light fixture, one or more transformers can be accommodated in one or both end caps 12 to supply the LED 14 with a suitable low voltage power supply.

It should be understood that modifications and substitutions that are obvious to those skilled in the art should not be considered as exceeding the scope of the present invention. For example, the inner surface of the tube 11 may be roughened, or provided with surface imperfections or protrusions, in order to better receive the light emitted by the LED 14.
