Referring now still to Fig. 3, in certain embodiments, photoluminescent layers 92 can apply to second electrode 84 to form luminous setting Standby 70 backlight type configuration.In certain embodiments, photoluminescent layers 92 can optionally or additionally configure and configure in front smooth formula In.Photoluminescent layers 92 can be applied to second electrode 84 as coating, layer, thin film and/or luminescence generated by light substrate or luminous set Standby 70 are configured to launch any surface of output transmitting 90 such as internal emission 40 or external emission 46, output transmitting 90 pass through this surface emitting.Output transmitting 90 figure 4 illustrates.Photoluminescent layers 92 can be by silk screen printing, flexographic plate print Brush and/or the alternate manner application being fixed to second electrode 84.
In various embodiments, LED emitter 78 may be configured to launch excitation-emission, excitation-emission comprise corresponding to The first wave length of blue light.LED emitter 78 may be configured to excitation-emission is transmitted in photoluminescent layers 92, so that light Electroluminescent material is excited.Excitation-emission is changed from first wave long shot by embedded photoluminescent material in response to receiving excitation-emission Output for comprising at least one second wave length launches 90, and second wave length is longer than first wave length.Additionally, one or more coatings 94 or sealant may apply to the outer surface of luminaire 70 to protect the other each of photoluminescent layers 92 and luminaire 70 Individual part from damage and is worn and torn.
Referring now to Fig. 4, show the detailed view of the photoluminescent layers 92 of luminaire 70 in backlight type configuration.Luminous Equipment 70 is configured similarly to the luminaire 70 shown in Fig. 3, have same reference numerals element have same or similar Function and structure.Although not shown in Fig. 4, LED emitter 78 is electrically connected with busbar 76,88 and power supply by controller, So that controller can optionally activate the excitation-emission 96 from LED emitter 78.
In the exemplary embodiment, excitation-emission 96 can comprise corresponding to blue light, purple light and/or ultraviolet spectra Color gamut.Blue color spectrum color gamut comprises the wave-length coverage that aggregate performance is blue light (~440-500 nanometer).At some In embodiment, first wave length can comprise positioned at ultraviolet and near ultraviolet color gamut (~100-450 nanometer) wavelength.In example In property embodiment, first wave length can approximate 470 nanometers.Although specific wavelength and wave-length coverage are carried out with reference to first wave length Illustrate, but first wave length totally may be configured to excite any embedded photoluminescent material.
In operation, excitation-emission 96 is transferred to the material of at least part of printing opacity of photoluminescent layers 92.Excitation-emission Can launch from LED emitter 78 and be configurable to make first wave length correspond to one or more embedded photoluminescent material to A few absorbing wavelength, this embedded photoluminescent material is arranged in photoluminescent layers 92.For example, photoluminescent layers 92 can comprise energy Amount conversion layer 98, energy conversion layer 98 is configured to for the excitation-emission 96 of first wave length to be converted to the output with second wave length Transmitting 90, second wave length is different from first wave length.Output transmitting 90 can comprise one or more wavelength, and one of which wavelength can With longer than first wave length.Excitation-emission 96 is made to be referred to as Stokes to the conversion of output transmitting 90 using energy conversion layer 98 Displacement (Stokes shift).
In certain embodiments, output transmitting 90 can correspond to multiple wavelength.Each of multiple wavelength can be right Should inconspicuous different spectral color scope.For example, the output transmitting 90 of at least second wave length can correspond to multiple wavelength (examples As second, third etc.).In some embodiments, multiple wavelength can combine to show as substantially in output transmitting 90 White light.Multiple wavelength can by the emitting red light embedded photoluminescent material of the wavelength with about 620-750 nanometer, there is about 526- The green emitting embedded photoluminescent material of 606 nanometers of wavelength, there is longer than first wave length and about 430-525 nanometer wavelength Blueness or aeruginouss light emitting photo-luminescent material produced.In some embodiments, blue or blue-green wavelengths can be right Should be in excitation-emission, excitation-emission is combined with output transmitting 90.As described herein, the concentration of embedded photoluminescent material is configurable to Allow that at least a portion excitation-emission is launched together with output transmitting 90, with to output transmitting 90 increase blue color.Multiple ripples Length can be used to the light of the multiple color from each luminescence generated by light part after first wave length conversion.Although here Refer to redness, green and blue particular color, but various embedded photoluminescent material can be used to multiple color and group Close to control the outward appearance of output transmitting 90.
Embedded photoluminescent material corresponding to photoluminescent layers 92 or energy conversion layer 98 can comprise organic or inorganic fluorescent Dyestuff, this fluorescent dye is configured to for excitation-emission 96 to be converted to output transmitting 90.For example, photoluminescent layers 92 can comprise The embedding benzene of naphthalene (rylene), ton (xanthene), porphyrin (porphyrin), phthalocyanine dye (phthalocyanine) or be suitable to The luminescence generated by light structure of the other materials of the specific Stokes shift being limited by absorption region and transmitting fluorescence.Real at some Apply in example, photoluminescent layers 92 can be at least one phosphor of the group selected from phosphor.Phosphor can With garnet group adulterated more particularly from cerium (Ce), such as YAG (yttrium-aluminium-garnet):Ce.So, each luminescence generated by light Partly optionally can be excited by being received from the various wavelength of excitation-emission 96, excitation-emission 96 is configured to excite One or more embedded photoluminescent material, thus transmitting has the output transmitting of required color.
Referring now still to Fig. 4, luminaire 70 may further include the coating 94 as at least one stabilized zone 100, stable Layer 100 is configured to protect the embedded photoluminescent material being included in energy conversion layer 98 not by photodissociation and/or thermal degradation.Stabilized zone 100 are configurable to be optically coupled to and adhere to the single layer of energy conversion layer 98.Stabilized zone 100 can also be turned with energy Change layer 98 to integrate.Photoluminescent layers 92 can also alternatively include optical coupled and adhere to stabilized zone 100 protective layer 102 or Photoluminescent layers 92 are protected not to be subject to any layer or the coating of physics caused by environmental exposure and chemical damage.
