The specific embodiment
For quote and know for the purpose of, the explanation of the technical term that uses in hereinafter and the accompanying drawing, write a Chinese character in simplified form or abridge and sum up as follows:
LED:Light Emitting Diode, light emitting diode.
Wavelength splicer spare is a difference of utilizing optical wavelength, two-beam is combined into the device of a branch of light.
How much splicer spares are the difference of utilizing the locus, two-beam are combined into the device of a branch of light.
In the description of the specific embodiment of the invention, use LED to come to specify for example.This does not limit the use of the Sony ericsson mobile comm ab of other type, and those skilled in the art can adopt the Sony ericsson mobile comm ab of other type that the led light source of being given an example among the present invention is directly replaced, and still can realize beneficial effect of the present invention.Sony ericsson mobile comm ab possibly be light emitting diode, laser diode or the luminescent device that uses at least a excitation fluorescent material generation fluorescence in light emitting diode and the laser diode, and both combinations at least arbitrarily among this three.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Can know by background technology; Though can be in the prior art one through red, green, blue, white light four LEDs being carried out close light how much simply; But because the optical extend of whole light source is the optical extend sum of four LEDs, so can't reach the requirement of high brightness.Though and the light source in the prior art two can be realized the bundle that closes of red, green, blue three-beam through conventional wavelength splicer spare (for example dichroic cross X plane); And optical extend can be controlled at about the optical extend of a LEDs; But existing conventional wavelength splicer spare can't exist big overlapping light beam effectively to close bundle a few bundle normalization spectrum; If for example in order to improve brightness; Need light beam and the red, green, blue three-beam that white light LEDs sends be closed bundle; Because the spectral region broad of the light that sends of white light LEDs, exist on the spectrum bigger overlappingly between the three-beam that itself and red, green, blue LED send, can not effectively close light by direct existing wavelength splicer spare.
After the present invention considers the defective of above-mentioned two kinds of prior aries just, proposed a kind of wavelength that adopts and closed the light source that light and how much closes the mode that light combines.
Hereinafter, use the energy of overlapped spectra in two normalization spectrum recently to describe the overlapping degree of two spectral light less than the less percentage of these two middle energy.The normalization luminescent spectrum 1501 and 1502 of two LED that for example in Figure 15, show, the energy of its overlapping part 1503 is the area in 1503 indicated zones.And normalization spectrum 1501 and 1502 energy separately is the area that it surrounds separately, and the energy of normalization spectrum 1502 is bigger slightly than normalization spectrum 1501.And the energy of overlapping part 1503 account for the less normalization spectrum 1501 of energy in two original spectrums energy 80%, then total energy loss will reach 30%～40% if use wavelength splicer spare that these two spectrum are closed light this moment.This is unacceptable for general optical system, so these two spectral light 1501 and 1502 need to be used and to be closed the light mode how much and close light.
In practical application, it is uncertain often to judge that can two spectrum use wavelength splicer spare to close the standard of light, because the emphasis that different application is paid close attention to is different.For example; Energy for overlapped spectra in two the normalization spectrum reaches 50% situation less than these two less percentages of middle energy; For paying attention to brightness but think little of the application of efficient; Can cause certain loss in efficiency though use wavelength to close light, be helpful to the growth of brightness, so may be used; And for the application of paying attention to efficient, wavelength closes light and then maybe not can be used.
In general, the energy of overlapped spectra more than or equal to 50% o'clock, owing to adopt the efficient of wavelength splicer spare too low, therefore often adopts how much splicer spares to close light less than the less percentage of these two middle energy in two normalization spectrum; And in two normalization spectrum the energy of overlapped spectra less than the less percentage of these two middle energy smaller or equal to 10% o'clock, often adopt wavelength splicer spare to close light; And in two normalization spectrum the energy of overlapped spectra less than the less percentage of these two middle energy less than 50% and greater than 10% o'clock, for example 20%, look concrete application and decide and adopt wavelength splicer spare to close light still to adopt how much splicer spares to close light.
Light source provided by the invention comprises at least one original luminescent device group and at least one light filling luminescent device group; The energy of overlapped spectra is less than 50% less LED of these two middle energy in the normalization spectrum each other to comprise at least two in the original luminescent device group, and all LED in the original luminescent device group close light through wavelength splicer spare.Preferably, comprise in the original luminescent device group at least two each other in the normalization spectrum energy of overlapped spectra less than 20% less LED of these two middle energy.Light filling luminescent device group comprises at least one LED, in the normalization spectrum of at least one LED in arbitrary LED of light filling luminescent device group and the original luminescent device group energy of overlapped spectra more than or equal to energy among both less 10%.
The mode that the light beam of the light beam of the final output of original luminescent device group and the final output of light filling luminescent device group closes light for how much through how much splicer spare utilizations is combined into a light beams.
The light source that the embodiment of the invention provides can be incorporated into original luminescent device group in the arbitrary LED spectrum light beam that another bigger LED sends that overlaps.
In the present invention, the light beam of the light beam of the final output of original luminescent device group and the final output of light filling luminescent device group carries out geometry and closes light on the different cross section of how much splicer spares, also can on same cross-sectional, carry out geometry and close light, and perhaps the two combines.
In addition; Needs according to reality; The type of LED in the original luminescent device group and number are to select flexibly according to the needs that show, the requirement that for example shows for three primary colours can comprise red-light LED, blue-ray LED and green light LED in the original luminescent device group.The inside concrete structure of light filling luminescent device group does not have any qualification; As long as in the normalization spectrum of wherein arbitrary LED and at least one LED in the original luminescent device group energy of overlapped spectra more than or equal to energy among both less 10%; Therefore light filling luminescent device group can be a white light LEDs itself, also can be the LED of many primary colours.Preferably, in the normalization spectrum of at least one LED in arbitrary LED of light filling luminescent device group and the original luminescent device group energy of overlapped spectra more than or equal to energy among both less 20%.More preferably, in the normalization spectrum of at least one LED in arbitrary LED of light filling luminescent device group and the original luminescent device group energy of overlapped spectra more than or equal to energy among both less 50%.
In addition; The type of how much splicer spares also can have a variety of, for example, can pass through single lens; Make light beam geometry on the incoming position of lens of original luminescent device group and light filling luminescent device group output splice, just can realize that the geometry of two light beams closes light; Can certainly realize above-mentioned how much splicer spares through two or more devices.
Whether following light beam according to the final output of original luminescent device group and light filling luminescent device group carries out geometry in same cross-sectional and closes light and specify each specific embodiment of the present invention.
Embodiment one
Fig. 3 shows a specific embodiment of the light source among the present invention, and in the present embodiment, the light beam of the final output of original luminescent device group and light filling luminescent device group is on the different cross section of how much splicer spares.For ease of describing, below used " top " " below " to represent the position relation between each components and parts, should be respectively top, below among the figure in " top " " below ".
Referring to Fig. 3; In the present embodiment; Comprise that with original luminescent device group the LED of three primary colours is that example describes especially, particularly, original luminescent device group 1 comprises red-light LED 11 (being designated as R among the figure), green light LED 12 (being designated as G among the figure) and blue-ray LED 13 (being designated as B among the figure).The number that it will be apparent to those skilled in the art that the LED in the optical device group is started in actual Central Plains does not have any qualification, can select flexibly according to the needs of actual displayed.Even if the displayed scene of three primary colours in addition also not necessarily is confined to the mode of the employing red, green, blue LED shown in Fig. 3.
Because it is overlapping less on normalization spectrum between two LED in the original luminescent device group 1; Usually in their the normalization spectrum energy of overlapped spectra less than two middle energy less 50%; So the mode through wavelength splicer spare utilizes wavelength to close light is closed light; In Fig. 3, being two with this wavelength splicer spare especially is parallel to each other and tilted-putted dichroscope (being designated as 14 and 15 in the drawings respectively) is an example; Should be understood that, the type and the quantity of wavelength splicer spare are not done concrete qualification here, as long as can utilize mode that wavelength closes light that the light that the LED of original luminescent device group sends is closed bundle.In the present embodiment, how much splicer spares are lens 31, and light filling luminescent device group 2 comprises a white light LEDs 21 (being designated as W among the figure).
Realize that when adopting wavelength closes the light time like two dichroscopes that are parallel to each other among Fig. 3 14,15; The position of red-light LED 11, green light LED 12 and blue-ray LED 13 can be adjusted flexibly; Can be as long as satisfy the light of wherein first LED output from the positive transmission of first dichroscope 14, and in the reflection of the front of second dichroscope 15; And the light of second LED output can be from the backside reflection of first dichroscope 14, and through the front reflection of second dichroscope 15; The light of the 3rd LED output can see through from the back side of second dichroscope 15; Finally from second dichroscope, 15 positive coaxial the getting final product of three light beams of exporting.
After the position of ruddiness LED11, green light LED 12 and blue-ray LED 13 is confirmed; Then need be according to the position of these three LED; The correct type of selecting two dichroscopes; For example; Adopt the position shown in Fig. 3 for red-light LED 11, green light LED 12 and blue-ray LED 13, then lean on first last dichroscope 14 to need the dichroscope of selecting to see through blue light and reflecting other wave-length coverage light, lean on second dichroscope down 15 to need selection and to reflect the dichroscope of other wave-length coverage light through green glow.
With Fig. 3 is example, and the inclination angle of first dichroscope 14 and second dichroscope 15 along continuous straight runs is 135 degree.Blue-ray LED 13 is arranged at the top of first dichroscope 14, and 13 luminous bundles of this blue led see through this first dichroscope 14, reflexes on the lens 31 through second dichroscope 15.Red-light LED 11 is arranged at the rear of first dichroscope 14, after the reflection of 11 luminous Shu Yici of this red-light LED through a dichroscope 14 and second dichroscope 15, is incident on the lens 31.Green light LED 12 is arranged at the rear of second dichroscope 15, and 12 luminous bundles of this green light LED see through second dichroscope 15, are incident on the lens 31.
Also comprise white light LEDs 21 in the present embodiment, in the normalization spectrum of at least one LED in this white light LEDs 21 and the original luminescent device group energy of overlapped spectra more than or equal to energy among both less 10%.For example, the energy of white light LEDs 21 is greater than the energy of the red-light LED 11 in the original luminescent device group, and in the normalization spectrum of white light LEDs 21 and red-light LED 11 energy of overlapped spectra more than or equal to 10% of red-light LED 11 energy.Preferably, the energy of white light LEDs 21 is greater than the energy of arbitrary LED in the original luminescent device group, and in the normalization spectrum of the arbitrary LED in white light LEDs 21 and the original luminescent device group overlapped spectra energy more than or equal to energy among both less 50%.Because the light beam of red-light LED 11, green light LED 12 and blue-ray LED 13 outputs closes bundle through wavelength splicer spare and also forms a kind of white light beam; This just make red-light LED 11, green light LED 12 and blue-ray LED 13 close light output light beam and white light LEDs 21 outputs the overlapped spectra of white light beam in normalization spectrum energy more than or equal to the energy among both less 10%; The mode that can not utilize wavelength to close light is again closed light, and adopts the mode of closing light for how much to close light.
In the present embodiment; The light beam of the final output of original luminescent device group; Be that the light of red-light LED 11, green light LED 12 and blue-ray LED 13 output beam and the output beam of white light LEDs 21 after wavelength closes light incides respectively on upper and lower two cross sections of lens 31, on these two cross sections, carry out geometry and close light.The cross section of lens refers to the lens cross section on the horizontal direction in the drawings among the present invention.
