Definitions
- the invention relates to a lamp and lamp corresponding thereto, comprising at least one LED which emits light within the visual spectrum from 380 nm to 780 nm wavelength (VIS range).
- lamps with light emitting diodes are used.
- the luminous efficacy of light-emitting diodes is very high and at the time of this application, the available luminous flux of light-emitting diodes is so high that they are in competition with incandescent lamps of comparable size and comparable production costs and also in an electrical consumption consideration.
- Light-emitting diodes generally have comparatively narrow spectral ranges in which they emit light.
- the desired color is white light - this is based on combinations of different colored light emitting diodes.
- white light one also resorts to various types of light-emitting diodes, which are arranged closely on a substrate.
- LED lamps Since it is primarily the goal of LED lamps to increase the luminous efficacy, the range of LED lamps within the visual range is usually optimized. Infrared components and also ultraviolet components are usually avoided because ultraviolet light or infrared light is imperceptible to the human eye.
- Lamps for use in quality control require a special spectral composition of their light color. This light color is not achievable with a light composition consisting exclusively of wavelengths in the visual range (VIS). Depending on the application, it is necessary, for example for the optical quality control of paints and surfaces, that ultraviolet light is mixed into the light spectrum. Known LED lamps are therefore not applicable in quality control.
- lamps in the medical field require - depending on the application - a special spectral composition, which can not be achieved with a light composition that exclusively consists of wavelengths in the visual range (VIS).
- VIS visual range
- lamps that have certain ultraviolet levels to stimulate melatonin synthesis in the human body The synthesis of melatonin causes a higher ability to concentrate and has an antidepressant effect.
- the light therapy of depressive patients can be helped with a special light composition, the patient to be cured of depression.
- Known LED lamps are therefore also in medicine or in the so-called medical field can not be used.
- Lamps for use in aquaristics and terraristics require a special composition of the emitted light.
- Aquaristics lamps require not only the visual spectrum (VIS) but also light components in the UV spectrum.
- Terraristic lamps require not only the visual spectrum but also IR spectrum.
- lamps for raising animals and also plants need special spectral composition of the light.
- These include breeding lamps for chickens and lamps for lighting plants.
- Chickens also have ultraviolet vision over human eyesight. Providing these lights to chickens for breeding means giving them a better orientation.
- Plants that are offered ultraviolet spectral components have - depending on the type of plant - a greater vitality, which affects the leaf color, leaf size and volume of green plant components.
- Known LED lamps are therefore not applicable in chicken farming.
- optical brighteners that are added, for example, to the surface coating of generic paper or white wardrobe are not effective in the purely visual range of light, because optical brighteners in the ultraviolet light fluoresce white or bluish and therefore shine brighter in the visual field than they seem to be illuminated.
- the object of the invention is therefore to provide an LED-based lamp having spectral components outside the visual range in the generated light.
- the lamp additionally emits radiation outside the light spectrum in the VIS range, in particular in the near-infrared range from 780 nm to 1.4 ⁇ m wavelength (IR-A range), in the middle Infrared range of 1.4 ⁇ m to 3.0 ⁇ m wavelength (IR-B range), in the near-ultraviolet range from 380 nm to 315 nm wavelength (UV-A range), in the middle ultraviolet range of 315 nm -280 nm wavelength (UV range). B range).
- a lamp according to the invention with at least one LED can therefore have, in addition to light-emitting diodes, which shine in the visual spectral range and with their combination to the human eye, or - depending on the type of mixture actually - white light, another light source, which in IR-A Range, in the IR-B range, in the UV-A range and / or also in the UV-B range.
- the LED lamps according to the invention have a lower light yield with respect to the visual luminous efficacy than known light-emitting diodes.
- the lamp is a combination of at least one visual LED, which can light red, green, blue but also white, another radiation source is attached.
- This radiation source can be an LED which radiates in the IR-A range, in the IR-B range, in the UV-A range and / or in the UV-B range.
- the portions of the light spectrum with respect to the radiated light energy which are outside the visual range, in this case have a proportion of 0.1% to 8%, preferably from 1% to 5%, particularly preferably 4%.
- the proportions of the light spectrum in the IR-A range, in the IR-B range, in the UV-A range and / or in the UV-BV range may together range from 0.1% to 8% or separate from one another range from 0.1% to 8%.
- Sources of ultraviolet light may be: an ultraviolet emitting LED, an ultraviolet or blue emitting LED with a coating of light salts or phosphor phosphors and / or gas discharge lamps whose light fraction in the total spectrum within the limits of 0.1% to 8%, preferably in the Limits of 1% to 5%, more preferably about 4%.
- Infrared light sources can also be LEDs that emit light in the IR-A range, LEDs that emit light in the IR-B range, but also conventional IR emitters.
- the future development in the industry read the lamp as a light source, as they are known today as a light bulb, fluorescent tube or LED lamp, merge with the entire lamp.
- the invention therefore relates not only to the lamp, but also to a lamp.
- FIG. 1 a spectrum set A, B, C, D of various LED lamps is shown, the VIS spectral component 1 is hidden here for clarity.
- the abscissa represents the wavelength ⁇ , while the ordinate indicates the intensity at a given wavelength ⁇ .
- Known LED lamps of the prior art with only one LED, an LED with light salts or phosphor phosphors, with a combination of different LEDs have in this VIS area 1 of the spectrum more than 99% of the light intensity, wherein in the spectral ranges within the VIS range 1 near the IR-A region 2 and the UV-A region 4 by known LED lamps hardly any radiation intensity is present.
- a of an LED lamp has a secondary maximum of the radiation energy in the UV-A region 4. Lamps with a clear peak in the UV-A range are suitable for stimulating melatonin production in the human body.
- Spectrum B of another LED lamp has less light intensity in this spectral range 4. These lamps are suitable for raising chickens or for illuminating samples in the optical quality control of paints and surfaces or for the promotional presentation of meat products.
- Another LED lamp has the spectrum C, yet another LED lamp has the spectrum D, which have a secondary maximum in the IR-A range and in the IR-B range.
- Such lamps are suitable, for example, for the presentation of baked goods.
