Embodiment Construction

[0038] Figure 1A and 1B A cross-section of an exemplary embodiment of an LED lighting unit 1 according to the invention is shown. The figure indicates one of a series of LEDs 10 mounted on a flexible lead frame 13 at the base of a container 12 or mixing box 12 . The translucent filler 14 covers the LED 10 and the lead frame 13 and acts to diffuse light to achieve a uniform appearance at the light exit opening 11 . Light is reflected from the inner surface 120 of the container 12 . in such as Figure 1A During the illuminated state of the lighting unit 1 shown, the LED 10 emits light L of a certain color (eg red, blue, green). 10 . This light exits directly through the light exit opening of the lighting unit 1 or after reflection at the side walls and / or scattering in the filling 14 . The light L leaving the lighting unit 10 will have the color of the light emitted by LED 10 . in such as Figure 1B During the unlit state of the lighting unit 1 shown, daylight L W Enter...

Abstract

The invention describes an LED lighting unit (1) comprising a container (12) with a number of partially reflective side walls (120); a light exit opening (11) defined by the side walls (120); and a number of light-emitting diodes (10) arranged in the container (12) to emit light (L10) of a first colour (CLED) through the light exit opening (11) during an on-state of the lighting unit (1). The LEDlighting unit is characterized in that the material properties of the partially reflective container side walls (120) are chosen to impart a second non-white colour (CPG, CPY, CPB) to the container side walls (120), and to absorb light in at least one specific region (S40, S41, S60, S70) of the visible spectrum such that light (L120) of the non-white second colour (CPG, CPY, CPB) exits the lighting unit (1) through the light exit opening (11) during an off-state of the lighting unit (1). The invention further describes a method of manufacturing such an LED lighting unit (1).

Description

technical field [0001] The present invention describes LED lighting units and methods of manufacturing LED lighting units. Background technique [0002] For many different types of lighting applications, it may be appropriate to use an LED lighting unit having one or more LEDs arranged at the base of a container or "mixing box". The emitting surface of the LED faces the light exit opening of the container and the side walls of the container or mixing box are usually highly reflective across the visible spectrum so that as much light as possible can exit the container through the light exit opening of the container. The LEDs can be mounted on a lead frame or carrier, which can even be flexible, allowing many possible shapes and forms of the lighting unit. For example, dozens of red emitting LEDs can be arranged on a length of flexible carrier and then formed to follow a curved shape at the rear of a car, so that a curved LED lighting unit can be used as a rear lighting unit ...
