Description
Technical field
The present invention relates to flashlight technical field, there are the laser flashlight optics of more optical axises more particularly, to a kind of
System and laser flashlight.
Background technique
Handheld lighting unit is also known as flashlight, since it is with extraordinary portable mobility, at many families
Outer and other extraordinary applications are used widely, such as outdoor mountain-climbing, exploration, police search and rescue, small space illumination scene.
The lighting apparatus of this hand-held is usually made of cylinder and cylinder head again, supplying cell built in cylinder, is set on cylinder head
There is specific luminescent device, applied to the luminescent device of flashlight, the most traditional is low power halogen bulb, this kind of light source
It develops the color, but brightness and efficiency do not have advantage, and it is its fatal disadvantage that the service life is short.Half followed by come into vogue in recent years
Conductor illumination LED, LED is as emerging light source, and luminous efficiency is high, the service life is long, stability is good, takes and generation in each application field
Conventional light source trend.But due to being applied to flashlight art, it is required that the high requirement of portability, either traditional halogen
Plain lamp or LED light source are not ideal point light sources, and it is many difficult that this gives the secondary optics applied to flashlight art to increase
Degree, brings unfavorable factor to the volume of flashlight.
So the development and application of the semiconductor laser technique of modern brings new machine to novel flash light again, due to semiconductor
The fabulous directionality of laser, close to point light source as perfect light source, and laser has the characteristic of high brightness, so answering
The advantage of application field for this directive property illumination of flashlight is especially prominent.The two features based on laser, can be with
It greatly reduces the volume of flashlight and keeps light irradiation distance farther.
But another problem existing for laser is exactly the safety problem of laser, also just because of the high brightness characteristic of laser,
Its energy density is high in the extreme, when using such powerful laser, due to using the eye being easy accidentally to related personnel
Eyeball or skin cause serious injury, or even to cause fire, scald etc. serious with injury, especially not to user's eyes
Reversible injury, so needs are especially careful when using high power laser.
Summary of the invention
The present invention is directed to overcome above-mentioned defect in the prior art, provide that a kind of there are the laser flashlight optics of more optical axises
The characteristics of system, the flashlight including the optical system makes full use of the fabulous directionality of laser and high brightness, realizes that high efficiency is remote
While range blanking, the risk using high power laser technology is greatly reduced, and flashlight is small in size.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: provide that a kind of there are the laser flashlights of more optical axises
Optical system, including incident optical system, Wavelength converter and outgoing optical system；Incident optical system include laser and
One optical reflector, laser for issuing exciting light, an optical reflector be used to carry out exciting light primary event with
Folded light beam forms more optical axises and guides folded exciting light to Wavelength converter；Wavelength converter is Lambertian scattering
