Embodiment three
Referring to Fig. 4, Fig. 4 is the structural representation of another embodiment of light-emitting device in this utility model embodiment.As
Shown in Fig. 4, light-emitting device 300 includes luminous source the 310, first lens 320, focussing mechanism (not shown), reflection unit
340, the first laser instrument 350 and the second lens 360.
The present embodiment includes in place of the difference of embodiment two:
(1) light-emitting device 300 also includes the reflecting mirror 370 being positioned on the emitting light path of the first lens 320, and this reflecting mirror exists
Projected area in first plane is less than the 1/4 of the first lens projected area on the first plane, and the first plane is for being perpendicular to
The plane of the first lens axis.
(2) being provided with light hole on reflecting wall 340, this light hole is used for the laser of transmission the first laser instrument 350 outgoing extremely
Reflecting mirror 370, this reflecting mirror is used for the laser-bounce from the first laser instrument to the first lens 320, and this laser is saturating through first
Mirror incident wavelength conversion equipment 310.Herein it should be noted that reflecting mirror herein is for the laser from the first laser instrument
It is reflection, is not offered as any light is all reflected.Wavelength converter 310 is that reflective (this is known technology, does not makees
Repeat), its emergent light outgoing is collected to the first lens 320 by the first lens 320.The Wavelength converter that first lens are collected
In the emergent light of 310, less than or equal to the direct outgoing of the light of the first angle to the second lens 360 or reflecting mirror 370, and more than first
The light of angle is reflected device 340 and reflexes to the second lens.
(3) reflecting wall 340 is conical surface, and the slope of this curved surface is along from the first lens to the direction of the second lens gradually
Increase, so that the light of reflecting wall reflection leans on antermarginal position within all reflexing to the second rims of the lens.In other embodiments
In, reflecting wall can also be the free form surface of Precise spraying.
Usually, making light source is conventional technology from lens focus out of focus, but has the best effect in the present embodiment
Really.Such as, when the first lens are close to Wavelength converter, laser just has out of focus for the first time when being incident in material for transformation of wave length
Effect, i.e. hot spot on material for transformation of wave length becomes big, then the first lens collect this become big after hot spot time be also
The collection of out of focus, so the angle of divergence of light-emitting device emergent light just becomes much larger.It is to say, is produced from the position of mobile first lens
Having given birth to the effect of twice out of focus, the angle of divergence of such emergent light is more sensitive for the displacement of the first lens so that luminous
The angle of divergence of device emergent light is easier regulation.Such as, in order to make the angle of divergence of light-emitting device emergent light be become 40 from 1 degree
Degree, needs the first lens are moved tens millimeters originally, and it is the most much of that the present embodiment has only to several millimeters of movement.
Therefore, the present embodiment regulates the distance from the first lens to Wavelength converter by arranging focussing mechanism, makes
The angle of divergence obtaining light-emitting device emergent light is adjustable.Further, the present embodiment utilizes the etendue amount of incident laser to be much smaller than
The feature of the etendue amount of the emergent light of Wavelength converter, less anti-of setting area on the emitting light path of the first lens
Penetrate mirror and carry out guided laser to Wavelength converter so that the position of mobile first lens can produce the effect of twice out of focus, thus
The angle of divergence making light-emitting device emergent light is easier regulation, therefore, it is possible to effectively meet the demand of different range of exposures.
In the present embodiment, owing to light path is reversible, the fraction emergent light of Wavelength converter 310, including Stimulated Light with not
The laser changed, can be through the first lens 320 outgoing to reflecting mirror 370, if reflecting mirror also reflects Stimulated Light, then Stimulated Light meeting
It is reflected by a reflector and escapes.This part light energy ratio owing to escaping is smaller, so being permissible in some occasion
Accept, such as hypermetropia occasion.In order to reduce light loss, reflecting mirror is preferably the laser and transmission reflected from the first laser instrument
From the optical filter of the Stimulated Light of Wavelength converter, such as reflection blue exciting light transmission yellow Stimulated Light.But, no matter why
Sample, the laser do not changed of Wavelength converter outgoing all can be reflected by a reflector and escape, the therefore area of reflecting mirror
The smaller the better, it is sufficient to receive the whole laser from the first laser instrument.
Additionally, in other embodiments, Wavelength converter can use LED as substrate, and material for transformation of wave length is (as glimmering
Light powder) it is arranged in the light-emitting area of LED in modes such as coating or pad pastings.Such as, when using blue led as Wavelength converter
Substrate time, the one side of material for transformation of wave length is by the exciting of laser from the first lens, and another side is swashed by this blue led
Sending out, i.e. material for transformation of wave length is two-sided is excited simultaneously, thus can improve the emergent light brightness of light-emitting device.For another example, use is worked as
When red LED is as the substrate of Wavelength converter, although material for transformation of wave length will not be excited by this red LED, but red
Outgoing together with the Stimulated Light that the HONGGUANG of LED outgoing can produce with material for transformation of wave length, thus increase HONGGUANG light for light-emitting device
The energy of spectrum, compensate for the defect that the red energy of Stimulated Light is not enough；Now reflecting mirror is preferably reflected excitation light and transmission is subject to
Laser and the light splitting optical filter of HONGGUANG.
Complicated, therefore to make up the redness energy of Stimulated Light owing to arranging the technics comparing of material for transformation of wave length on LED
The defect that amount is not enough, light-emitting device can also include that second laser, the laser of the first laser emitting go out with second laser
The laser penetrated is combined into beam of laser and is incident to reflecting mirror 370；Second laser is preferably red laser or green laser,
Make outside Wavelength converter outgoing exciting light and Stimulated Light, red laser that also outgoing has been scattered by material for transformation of wave length or
Green laser, thus increase red-light spectrum or the energy of green spectrum for light-emitting device.Second laser can also be infrared sharp
Light device, can be so the energy of light-emitting device increase infrared spectrum, in order to user can pass through infrared light detecting at night
Device finds this light-emitting device.
In other embodiments, reflecting mirror 370 can also replace with big light splitting optical filter, and the reflection of this light splitting optical filter swashs
Light and transmission Stimulated Light, in the emergent light of the Wavelength converter 310 that the first lens are collected, go out less than or equal to the light of the first angle
It is incident upon this light splitting optical filter, and is reflected device 340 more than the light of the first angle and reflexes to the second lens.
