In the LED light 11 of Fig. 1 and Fig. 2, center luminescent wafer 14 is that side length is the rectangular of 1mm, and is had across crystalline substance The optical axis A at the center of pieceO.The Center Wafer 14 is located so that the optical axis A of Center Wafer 14oAcross the focus of optical element 22 24.Light radiates on a series of radiation paths from Center Wafer 14, and radiation path forms the hemisphere of light, this can be referred to as " bright Primary body (lambertian) " radiation mode.The physical size of Center Wafer 14 mean some light be from optical element 22 Optical axis AoThe position transmitting being spaced apart with focus 24.Substantially, optical element is all passed through from all light that Center Wafer 14 emits Refractive surface 26, and received by the translucent material of optical element 22, this material can be by silicone, polycarbonate, propylene The materials such as acid or glass are constituted.Once light will be mobile according to well-known principle, than Nie Er like that into optical element 22 Law.Light is incident in the interior reflective surface 30 of 22 periphery of optical element with being greater than the angle of critical angle, is reflected to basis The direction of light and its in the track of the incidence angle in interior reflective surface 30.In the embodiment disclosed in fig. 1, refracted light incident face 26 and light reflective surface 28 be located at the bottom and top of optical element 22, with the internal reflection table for being located at 22 periphery of optical element Face 30 cooperates, and the radiation path of the light from Center Wafer 14 is changed into the optical axis A substantially with Center Wafer 14oAlignment Launching track (launching track is overlapped with the axis A in Fig. 1).Inner reflection surface 30 can metallize to reduce through the table The leakage of the light in face.
Figure 1A shows the optical transmission mode from Center Wafer 14 and TIR light element 22.The figure shows relative to Emission mode corresponding with about 10 ° of collimation " hot spot " light beams of 0 ° of center line that axis A is overlapped.Or it may also be said that from center The emission mode that chip 14 passes through collimation optics 22 generates light beam, wherein essentially all of light appointing relative to axis A Side anticipate all with 5 ° or the transmitting of smaller angle.It is located in emission mode by the largest beam intensity that Center Wafer 14 generates The heart, when graphically present, similar to relatively sharp, the narrow spike centered on axis A.Figure 1A is also shown Pass through the emission mode of collimation optics 22 from peripheral wafer 16.Peripheral wafer 16 generates the center relative to optical element 22 The light of axis A " off-axis ".The light generated by peripheral wafer 16 will not be collimated by optical element 22, and around by Center Wafer 14 The Mode Launch of the hot spot light beam of generation.It is understood that it is brilliant to change center relative to the power for being transmitted to peripheral wafer 16 The power of piece 14, the emission mode that the axis A divergence generated relative to optical element 22 is changed.When Center Wafer 14 and outside When enclosing chip 16 and being all powered, it is filled with the center from 16 emission mode of peripheral wafer from the light emitting of Center Wafer 14, to mention For the wide-angle floodlight emission mode from lighting module 10.
Pack optical element 22 extremely efficiently handles the light from Center Wafer 14, it means that the light of relatively small amount Flux can generate clearly hot spot light beam.Because light caused by Center Wafer 14 is processed and focuses on zonule It is interior, so hot spot light beam also has high luminous intensity.The efficiency of the processing of optical element 22 light as caused by peripheral wafer 16 It is relatively low, it means that some light are lost in optical element, and some light to expected floodlight emission mode without shadow Emit on loud track.In addition, the light emitting amount to be filled of peripheral wafer 16 is much larger than the light filled by Center Wafer 14 Emission measure.Due to these factors, total luminous power of peripheral wafer 16 is greater than total luminous power of Center Wafer 14.Even if each Peripheral wafer 16 is likely less than Center Wafer 14, but total lumen that peripheral wafer 16 generates is greater than total stream that Center Wafer 14 generates It is bright.In addition, the consumed power when generating larger luminous flux of peripheral wafer 16 is greater than power consumed by Center Wafer 14.
Fig. 2 is the top view of the LED light 11 of Fig. 1, the ceramic substrate 12 for luminescent wafer is shown, according to the disclosure Various aspects, LED light 11 include Center Wafer 14 and a large amount of lesser peripheral luminescent wafers 16.Although showing in relatively large Heart chip 14 and lesser peripheral wafer, but the relative size of chip 14,16 is without being limited thereto.In disclosed LED light 11, Center Wafer 14 and peripheral wafer 16 link together, so that Center Wafer 14 can separate energization with peripheral wafer 16.Outside Enclosing chip 16 can connect together as one group of energization, or as the subset that can be individually powered.Peripheral wafer 16 is in The optical axis A of heart chipoLateral separation, and also with 24 lateral separation of focus of optical element 22.This means that from peripheral wafer The light of 16 radiation will emit not as collimated light beam from optical element 22, but as the light more dissipated as shown in Figure 1A Beam transmitting.When graphically present, there is lower intensity along axis A by the light beam that peripheral wafer 16 is formed, wherein The most of light emitted within the scope of certain angle is diffused to relative to axis A to about 45 °.From the transmitting mould of peripheral wafer 16 Formula can be described as a kind of " floodlight " optical transmission mode, but especially lack intensity along axis A.In the illumination mould of Fig. 1 and Fig. 2 In block 10, the peak strength of the emission mode from peripheral wafer 16 deviates about 20 ° from axis A, as shown in Figure 1A, it means that The peak strength and axis A of light from peripheral wafer 16 dissipate about 20 degree.
The LED illumination module 10 of Fig. 1 is configured so that Center Wafer 14 and peripheral wafer 16 can together or individually It is powered.Furthermore, it is possible to the light emitting intensity from Center Wafer 14 and peripheral wafer 16 be modulated, to generate from focus point to wide-angle The optical transmission mode of floodlight.It is powered in reduced level for example, Center Wafer 14 can according to need, with filling by peripheral brilliant The center for the floodlight emission mode that piece 16 generates.In general, hot spot optical transmission mode is the object for illuminating distant place, or it is used for Generate the visible warning optical signal at a distance such as in beacon.Floodlight emission mode can be used for illuminating construction operation area, hand over The scene etc. of interpreter's event.The LED illumination module 10 of Fig. 1 can provide hot spot, floodlight from single optical element 22 or mix this The various emission modes of the two, the optical element 22 can have single focus 24 and without using moving parts.
The arrangement of peripheral wafer is not limited to shape identical with Center Wafer.For example, the peripheral wafer 16 in Fig. 2 is around side Shape Center Wafer 14 arranges squarely.Three chips can be removed from the corner that peripheral wafer 16 is arranged, " x " table is used in Fig. 2 Show these chips.Removing three peripheral wafers 16 in the corner of bracket will lead to the more round light emitting from optical element 22 Mode.The arrangement of peripheral wafer 16 is the example according to " ring " of the peripheral wafer 16 of the disclosure in Fig. 2.
Fig. 3 is the top view of ceramics bracket 12, shows a kind of alternating pattern of luminescent wafer, wherein "center" shines Chip 32 is made of 9 lesser chips 34.In this embodiment, it is configured to make close to 34 groups of 9 chips of the center of bracket Centered on group 32 be powered together, wherein be configured to be powered together around the peripheral wafer 36 of the central set or lead in subset 38 Electricity.As shown in figure 3, the group of 9 peripheral wafers 36 is connected in subset 38 by cross spider, subset 38 connects into be powered together.Son Collection may include the chip of equal amount as shown in Figure 3 or the chip of unequal quantity.Bracket 12 and luminescent wafer 34,36 It will work as described in the embodiment above for Fig. 1 and Fig. 2, and only with respect to centered in group 32 The grouping of the construction and peripheral wafer 36 of heart chip is different.
Fig. 4 A shows the selectable grouping of luminescent wafer, wherein 8 peripheral wafers 16 surround Center Wafer 14.TIR Optical element 22 is shown schematically in front of chip 14,16.Center Wafer 14 and peripheral wafer 16 are configured to individually be powered.
