Embodiment Construction

[0044] figure 1 The sectional view in side view shows an LED lighting device 11 in the form of an incandescent retrofit lamp. The LED lighting device 11 has a heat sink 12 , for example made of aluminum, on its rear side an electrical connection 13 , such as an Edison lamp socket or a two-pin lamp socket (eg type Typ GU), is present. The heat sink 12 has a driver cavity 14 in which a driver 15 is located. The driver 15 is electrically connected to the electrical connection 13 and feeds a plurality of light-emitting diodes 16 , 17 , 18 . The light-emitting diodes 16 to 18 are mounted on a common ceramic substrate 19 which is attached to the front side of the heat sink 12 . Furthermore, the front side of the heat sink 12 carries an opaque bulb 20 , which protrudes over the light-emitting diodes 16 to 18 .

[0045] as in figure 2 As shown in the sectional view A-A through the piston 20 perpendicular to the longitudinal axis L, the ceramic substrate 19 is annular and the ligh...

Abstract

The LED lighting device (11) has at least one mint-coloured light-emitting diode (16), at least one amber-coloured light-emitting diode (17) and at least one yellow light-emitting diode (18) and / or blue light-emitting diode.

Description

technical field [0001] The invention relates to an LED lighting device, which has at least one mint-colored light-emitting diode and at least one amber-colored light-emitting diode (Brilliant Mix color and light perfect match). The invention can be advantageously used in particular in retrofit lamps, in particular incandescent retrofit lamps, especially for decorative purposes. Background technique [0002] Many LED modules are known in which InGaN chips and InGaAlP chips are combined. An application example is the combination of phosphor-converted, mint-emitting InGaN chips (blue LED chips with (yellow) green phosphors) together with amber-emitting InGaAlP chips for color rendering High warm white mixed light. Such LED modules are also known as "Brilliant Mix", for example in the company publication "Billiant Mix—Professional White for General Lighting" by the company Osram Opto Semiconductors, January 2011. Such a "Brilliant Mix" is also described, for example, in DE 10...
