Definitions
- the invention relates to a luminaire for emitting an electromagnetic radiation with an LED radiation source (LED: light-emitting diode) for generating a white light.
- LED radiation source LED: light-emitting diode
- Optical brighteners require an electromagnetic radiation from a wavelength range of approximately between 280 nm and 425 nm for their action, ie in particular also includes the UV range. (The transition from the ultraviolet radiation to the visible region is about 380 nm.)
- the usual LED light sources contain virtually no UV component, so that they can hardly excite optical brightener and in this way causes the effect described above.
- FIG. 3 For a more detailed illustration of the underlying relationships, a diagram is shown in FIG. 3, in which the wavelength ⁇ on the abscissa
- the absorption spectrum of a typical brightener is outlined by a curve Kl. This spectrum extends approximately to a wavelength of about 425 nm and has a maximum at about 375 nm. Furthermore, another curve K2 is shown, which is the corresponding
- Emission spectrum of the brightener shows.
- the reason for this shift in the spectrum is fluorescence.
- the emitted spectrum has a maximum at about 437 nm and corresponds predominantly to a violet-blue light. Because of this Emission spectrum is thus the blue portion of the radiation, which emanates from the corresponding irradiated white product increases. This will eventually produce the effect that the whites appear “purer” or less yellowish. "In the following, this effect is also referred to as” excitation "of the optical brightener.
- the invention has for its object to provide a corresponding improved luminaire.
- the light should be particularly well suited for lighting white objects.
- This object is achieved according to the invention with the object mentioned in the independent claim.
- Particular embodiments of the invention are indicated in the dependent claims.
- light is for radiating an electromagnetic
- Radiation which has a first LED radiation source for generating a first portion of the radiation in the form of a white light. Furthermore, the luminaire has a second LED radiation source for generating a second portion of the radiation, wherein the second component only radiation having wavelengths within the wavelength range of about 280 nm to about 425 nm.
- the second component makes it possible, in particular, for optical brighteners, as they occur, for example, in white products, to be able to exert their effect, at least significantly better, so that subsequently the product appears in a "purer" white.
- the lamp is designed such that the electromagnetic radiation to whose emission the lamp is configured, composed only of the first portion and the second portion. In this way, the ratio between the two mentioned shares can be set particularly well.
- the second portion only comprises radiation having wavelengths within the wavelength range from about 280 nm to about 400 nm, more preferably from about 280 nm to about 380 nm.
- the second portion may be between about 370 nm and about 380 nm. Because in this area the absorption maximum optical brightener, can be achieved energetically particularly advantageous in this way excitation of the optical brightener. In addition, it is achieved in this way that the light emitted by the lamp as a whole is practically not affected by the second component in its color appearance. The "color point" of the light emitted by the lamp experiences in this case - viewed on a standard color chart - by the second portion virtually no "color shift". In practice, LEDs are currently preferred, which emit light with a wavelength of about 385 nm. Such LEDs are readily available and accordingly can be used inexpensively for the purposes of the present invention.
- the lamp further comprises a control unit for driving the first LED radiation source and the second LED radiation source, wherein the control unit is designed such that the intensity of the first portion is greater than zero, when the intensity of the second portion is greater than zero ,
- the lamp If the first portion is greater than zero, the lamp emits light; This generally has the consequence that a viewer of the lamp - because of the associated glare - does not look directly into the light output range of the lamp. Therefore, the risk of damage to the eyes of the observer by UV radiation can be reduced if the control unit is designed in such a way that UV radiation is only emitted from the luminaire when it emits light.
- control unit is preferably further configured such that the intensity of the second portion can assume at most a maximum value, which is dependent on the intensity of the first portion, in particular proportional to the latter.
- the intensity of the second portion can assume at most a maximum value, which is dependent on the intensity of the first portion, in particular proportional to the latter.
- the control unit is designed such that the intensity of the second portion is adjustable up to the maximum value, preferably at constant intensity of the first portion. Through this adjustment can be achieved that the light - with a certain light output - can be operated with a more or less intense second portion or UV content. For example, if the LED light is used to illuminate colored objects, it is usually advantageous to control the second part down, that is, to reduce the intensity of the second part.
- the lamp is on the one hand particularly good for the irradiation of white objects, on the other hand, but also for the irradiation of colored objects.
- the lamp is designed so that the intensity of the second portion is continuously adjustable up to the maximum value, for example by means of a
- control unit is further configured such that the intensity of the second portion is adjustable to the value zero or can be turned off.
- the lamp is also particularly well suited for the irradiation of colored surfaces.
- the luminaire further comprises at least one optical element for influencing a radiation emitted by the first LED radiation source and the second LED radiation source, wherein the at least one optical element with respect to the spectrum of the second portion has a transmittance which is at least 60% , preferably at least 70%.
- the lamp is designed in the form of a spotlight, it is particularly suitable for lighting products in shops and the like.
- FIG. 1 is a perspective sketch of an LED lamp according to the invention
- Fig. 2 is a schematic sketch of a circuit board of the lamp with the first LED radiation source and second LED radiation source arranged thereon and
- Fig. 3 is a diagram of the absorption and emission behavior of a
- Fig. 1 shows - partially cut - schematically an LED lamp according to the invention in the form of an LED spotlight.
- the LED lamp - hereinafter also referred to as luminaire for short - is designed for the emission of electromagnetic radiation.
- the luminaire preferably comprises at least one circuit board 3, as again shown very schematically in FIG. 2 in separated form.
- the luminaire has a first LED radiation source 1 for generating a first portion L of the electromagnetic radiation, to the radiation of which the luminaire is designed.
- the first component L is a white light.
- the first LED radiation source 1 can comprise a plurality of individual LEDs or consist of the latter. These LEDs of the first LED radiation source 1 may be white light LEDs known per se, for example LEDs that generate blue light, which is subsequently partially converted into yellow light by a color conversion material, so that white light appears overall is dispensed and / or RGB LEDs.
- the lamp has a second LED radiation source 2 for generating a second portion UV of the radiation to the radiation of the lamp is designed.
- the second component t / F comprises exclusively radiation having wavelengths within the wavelength range from about 280 nm to about 425 nm.
- the second component UV may consist in particular of radiation which is only in the ultraviolet
- Range of radiation is, in particular in the wavelength interval of about 280 nm to about 380 nm.
- the reference UV for the second portion is chosen to remember this relationship.
- “about” is meant in connection with a wavelength specification, a small wavelength range, the
- ⁇ 20 nm or ⁇ 30 nm may mean.
- the LED light illuminates a white object that has an optical brightener, the latter emits blue light, making the object appear particularly pure white.
- the lamp is designed such that the electromagnetic radiation to whose emission the lamp is configured, composed only of the first portion L and the second portion UV.
- the second portion UV only comprises radiation having wavelengths within the wavelength range from about 280 nm to about 400 nm, more preferably from about 280 nm to about 380 nm.
- the second portion may be between about 370 nm and about 380 nm.
- the second LED radiation source 2 may be designed such that the second portion UV has a maximum at a wavelength which is in the range from 280 nm to 380 nm, particularly preferably in the range from 370 nm to 380 nm second LED radiation source 2 is designed so that it emits radiation having a wavelength spectrum having a maximum at about 375 nm, for example at 375 nm ⁇ 15 nm, then can - due to the absorption spectrum described above of a typical brightener, as in Fig. 3 is outlined - with comparatively lower
- the lamp can be designed overall with particularly good efficiency.
- the wavelength maximum of the second component UV is below 400 nm, particularly preferably below 380 nm, because in this case the color location of the light emitted by the lamp is changed very little by the second component UV.
- LEDs are currently primarily available which emit light with a wavelength of about 385 nm, these LEDs are currently being used for reasons of cost, even if the light of these LEDs is just outside the particularly preferred range in terms of its wavelength.
- the first LED radiation source 1 and the second LED radiation source 2 are arranged on the at least one circuit board 4.
- the second LED radiation source 2 may comprise only one LED, as shown by way of example in FIG. 2, but in general it may also consist of a plurality of LEDs.
- the second LED radiation source 2 consists of fewer LEDs than the first LED radiation source 1, because it usually suffices to excite the optical brightener when the second component UV is lower in comparison to the first component L.
- the lamp further comprises a control unit for controlling the first LED radiation source 1 and the second LED radiation source 2, wherein the control unit is designed so that the intensity of the first portion L is greater than zero, when the intensity of the second component UV is greater than zero.
- the control unit is designed so that the intensity of the first portion L is greater than zero, when the intensity of the second component UV is greater than zero.

- the at least one optical element 4 is designed such that it is at least 60%, particularly preferably at least 70% permeable with respect to the spectrum of the second portion UV. This is energetically advantageous with respect to the effect of interest here.
- the lens 41 may have a transmittance for the second portion UV, which is greater than 60%>, preferably greater than 70%>.
- the lens 41 is designed as a primary optic element and the reflector 42 as a secondary optical element.
- the reflector 42 is formed in the first approximation cone-shaped section and through the thus formed larger opening the light emitting surface of the lamp is fixed.
- the luminaire is preferably configured such that the first component L generated by the first LED radiation source 1 and that of the second LED Radiation source 2 generated second portion UV only the at least one optical element 4 penetrated before they leave the lamp to the outside. This makes it possible to avoid a further weakening of the second UV component.

- the lamp is on the one hand for the irradiation or illumination of white objects, on the other hand, but also for the irradiation of colored objects.
- the design is furthermore preferably such that the intensity of the second component UV can be set to zero.
