- the inner layer may at least partially enclose the driver circuit 5.
- the lower part 4 has an advantageous manner an opening on the bottom, whereby the driver circuit can protrude or through which a conductor can protrude, which establishes an electrical contact with power supply.
- the upper part 6 also has a bulged outward shape, so that there is sufficient space on the inside for the driver circuit. On its outside, preferably in the middle of the bulge, it has a flat area on which the LED module 7 is mounted.
- the upper part 6 may thus have an approximately hemispherical shape, which is flattened on its upper side.

Thus, the driver circuit can be further protected against short circuits. It is conceivable that this insulating layer in the area below the LED module has a recess, so that via the inner, conductive layer, an electrical connection between the driver circuit and the LED module can be made. However, it is also conceivable that the third layer is formed continuously and inner layer and the third layer in the region of the LED module are pierced to make contact with conductors.
- the LED module 7 may have a common circuit board 30 on which at least 2 LED chips 20, 21 are applied.
- the LED chips 20, 21 preferably emit light with different spectra.
- the LED chip 20 can emit white light under phosphor conversion, while the LED chip or chips 21 can emit monochromatic light, for example in the reddish range.
- a particular embodiment relates to the fact that by appropriate individual control of the LED chips 20, 21 with different spectra, the mixing spectrum of the LED lamp, for example, color temperature of white light, is adjustable.
- the invention generally proposes to provide an at least two-shell diffuser element with a primary diffuser element 10 and the upper part 8 acting as a secondary diffuser. If the invention is described in the context of the present description with reference to an example candle-shaped retrofit LED lamp element, it is still apparent that the invention can also be applied generally to LED modules, in particular those in which at least two LED chips with different emission spectrum are arranged at the same level.
- the primary diffuser element 10 can surround the LED chips 20, 21 like a hood.
- This can be a rounded hood (for example with an U-shaped or box-shaped cross-section).
- the hood-shaped primary diffuser element 10 is designed such that the edge region of the hood completely surrounds the LED chips 20, 21 at least laterally.
- the hood-shaped primary diffuser element 10 is pulled down even further, namely onto the heat sink body 6 which in turn is mounted in thermal contact plate 30 of the LED module 7.
- Both the upper part 8 and the primary diffuser element 10 can be made of a plastic material, for example polycarbonate, polystyrene, polyester, polymethyl methacrylate (PMMA) or their copolymers.
- the diffuser elements can be made of a plastic material, for example polycarbonate, polystyrene, polyester, polymethyl methacrylate (PMMA) or their copolymers.
- the diffuser elements can be made of a plastic material, for example polycarbonate, polystyrene, polyester, polymethyl methacrylate (PMMA) or their copolymers.
- PMMA polymethyl methacrylate
- the plastic particles Contain plastic particles, wherein the refractive indices of the particle core and particle shell preferably do not match.
- the plastic particles can be distributed in a polymer matrix.
- the two diffuser elements can also be made of glass or glass-plastic mixtures.
- the secondary diffuser element (upper part) 8 is preferably spaced apart from the primary diffuser element 10 to form an air gap with an average minimum distance of, for example, at least 1 mm, preferably at least 3 mm.
- the primary diffuser element and the secondary diffuser element may be fabricated as an integral double-shelled piece.
- the primary diffuser element 10 is preferably at a homogeneous or inhomogeneous distance of at least 1mm, more preferably at least 2mm, again preferably with the formation of an air gap (a gap filled with gaseous medium), spaced from the respective nearest LED chip 20, 21.
- the wall thickness of the primary diffuser element 10 and / or of the upper part 8 acting as a secondary diffuser can each be homogeneous or inhomogeneous.
- the homogeneous or inhomogeneous wall thickness can be between 0.1 mm and 5 mm, preferably between 1 mm and 3 mm.
- the region 50 of the primary diffuser element 10 located above the LED chips 20, 21 may have a reduced wall thickness compared to the region 60 of the hood-type primary diffuser element 10.
- the primary diffuser element 10 can be mounted on a support, for example on the circuit board 30 of the LED module 7 mechanically (by clips, locking, gluing, etc.).
- the primary diffuser element 11 may also be formed dome-shaped.
- Fig. 3 an embodiment is shown, in which the primary diffuser element 12 is arranged directly on the board 30 of the LED module 7, and the LED chips 20, 21 carries. Light from the LED chips 20, 21 is thus diffused by the primary diffuser element 7, 11, 12. Since the human eye can not look directly at the primary diffuser element 10, 11, 12 when the LED lamps are mounted, but only at the secondary diffuser element in the form of the upper part 8, it is advantageously no longer possible to perceive color separation. Thus, even when looking directly at the edge region 40 of the secondary diffuser element 8, the human eye will see a mixed spectrum of the LED chips 20, 21, but no spatially separated color effects.
- the first and / or second diffuser element can have color conversion means ("remote color conversion") which are present, alternatively or in addition to a color conversion layer, directly, i.e. without an air gap, over one or more of the LED chips.
