Abstract

A retrofit LED lighting system with a combination of a directional downlight component and an indirect uplight component is provided. The system comprises light emitting diodes arranged so as to replicate the function of a legacy light source in a transparent or translucent fixture housing. The LED lamp includes upwards facing LEDs emitting light upwards, and a translucent stem covering the uplight LEDs to allow the light from the LEDs to pass through it. Advantageously, the LED lamp with uplight component and a transparent/translucent stem allows the light to be directed upwards and hence, avoids having a sharp cut-off of light appearing in the middle of the reflector fixture and also avoids a lack of uplight shone on the ceiling.

Claims (10)

1. A LED retrofit lamp, comprising:

a lamp housing having a first array of light emitting diodes, said first array comprising at least one downlight LED, and a second array of light emitting diodes, said second array comprising at least one uplight LED;

a diffuser coupled to a distal end of the lamp housing to allow light emitted by said at least one downlight LED to pass through; and

a stem coupled to a proximal end of the lamp housing to allow light from said at least one uplight LEDs to pass through it.

2. The LED retrofit lamp of claim 1 wherein the lamp housing is made of a transparent or a translucent material.

3. The LED retrofit lamp of claim 1 , wherein the stem is made of a transparent material or a translucent material.

4. The LED retrofit lamp of claim 3 , wherein the stem is made of glass or acrylic.

5. The LED retrofit lamp of claim 1 , wherein the lamp housing is circular, semi-circular, cylindrical, rectangular, parabolical or square shaped.

6. The LED retrofit lamp of claim 1 , wherein the LED retrofit lamp is configured to operable on a magnetic ballast, a fluorescent ballast or a direct AC source.

7. The LED retrofit lamp of claim 6 , wherein the LED retrofit lamp is configured to operable on a magnetic ballast.
