Description
Technical field
The present invention relates to the technical fields of illuminating device, more particularly, to a kind of LD laser light source mould group for keeping off blue light.
Background technique
The full name in English of LD is Laser diode, and Chinese is laser semiconductor, also referred to as laser diode.Swash
Light be it is a kind of by induction release the device of light amplification.Existing laser semiconductor be generally used for fiber optic communication, CD,
The fields such as laser printer, laser scanner, laser designator (laser pen), and in lighting area, light source module group is generally all
It is using LED as luminescence medium, LED is commonly called as semiconductor light-emitting-diode；And use LD laser light source mould group as light source
Illuminating product is more rare.
On the other hand, at work, the light of sending is blue light to LD semiconductor laser diode, meanwhile, as shown in figure 4, often
The wide smaller range value X that a LD semiconductor laser diode issues be it is determining, from center to surrounding shine, be a loudspeaker
Shape is the same.The available blue light range value Y of light source module group is variable and controllable numerical value, but Y is centainly less than
Or it is equal to X (that is: Y≤X), the blue light light of qualification needed for product could be obtained.Extra blue light or scattered blue light, it is right
It for entire light source module group, does not utilize, influences light-out effect instead.For example, being white when entire light source module group goes out light
Light time just has veiling glare if these blue lights do not block, then will have blue light influence in light-emitting window, leads to light-out effect not
It is ideal.
Summary of the invention
The present invention is directed to overcome at least one defect of the above-mentioned prior art, the LD laser light source light of a kind of grade of blue light is provided
Film, for solving going out for Technical comparing scarcity and LD light source module group of the current flashlight industry using LD light source as luminescence medium
Optical port has blue light influence, the undesirable technical problem of light-out effect.
The technical solution adopted by the present invention is that a kind of LD laser light source mould group for keeping off blue light, including LD light source, LD light source hair
Light out is blue light, and the optical channel that goes out of LD light source is equipped with laser connecting plate, and laser connecting plate is equipped with light through-hole, wherein
The size of light through-hole is less than the diameter of emerging beam of the LD light source on laser connecting plate out, and the light through-hole out is for limiting LD
Light source goes out the beam diameter range of light on laser connecting plate.
In the technical program, LD light source is blue light in horn-like light out, the light of sending, wherein the center from emerging beam
Remoter light belongs to scattered or extra blue light, and without utility value, therefore, the technical program is led to by the light that goes out in LD light source
Light through-hole is provided on road, light through-hole passes through for limiting scattered or extra blue light out, so that LD light source goes out light efficiency
Fruit is more preferable, and light is more concentrated.
In the technical program, the shape of the light through-hole out can according to need setting.Wherein, the size of light through-hole out
Less than the diameter of original LD light source emerging beam in the same plane, the shape of light through-hole can be set to rectangle, pros out
Shape, circle, ellipse, diamond shape, star, curve form or irregular shape etc..
The light source module group of the technical program is using LD laser diode as light source, the luminous power of LD laser diode
Height, the brightness of a LD light source are the summations of several hundred a LED luminances, therefore, the LD light source of equivalent amount and the LED of equivalent amount
Light source compares, and LD light source has higher colour brightness, farther irradiation distance and higher clarity；And LD light source issues
Light there is better wavelength characteristic, direction collimation property and phase characteristic and other effects, substantially increase out distance, the brightness of light
And clarity.
On the other hand, the LD laser light source mould group being made of the LD laser diode technical solution new as one kind, due to
Only with one chip LD laser diode as luminescence medium, therefore LD laser light source mould group obtained is meeting brightness
It is required that while, the volume of product is smaller, carries more convenient.
Further, the side wall that the LD light source goes out optical channel is sealed around, so that the emerging beam of LD light source can only be from
Optical channel projects out.
The side wall that LD light source goes out optical channel is sealed around, and then can effectively avoid the light guide of LD light source saturating from side wall
Light influences light-out effect.Therefore, LD light source goes out that optical channel side wall is sealed around can emerging beam more be concentrated.
Further, the optical channel that goes out of the LD light source is equipped with reflection subassembly and powder piece, and it is glimmering that powder on piece is coated with yellow
Light powder, the light beam reflection that the reflection subassembly is used to issue LD light source is in powder on piece, the yellow fluorescent powder and LD light of powder on piece
The light beam that source issues, which combines, becomes white light, then white light reflection is gone out through powder piece；Wherein, the reflection subassembly and powder piece are set to
After light through-hole.
Powder piece, which belongs to non-transparent eyeglass, will become white light after the yellow fluorescent powder of powder on piece coating is in conjunction with blue light, into
And the emerging beam of LD light source is made to be white light beam.Since powder piece belongs to non-transparent eyeglass, the technical program passes through
Reflection subassembly, which reflects the emerging beam of LD light source, goes out white light reflection in powder on piece, then by powder piece.
It is more than light if being not provided with out the range of the emerging beam of light through-hole limitation LD light beam in the technical program
A certain range of light beam be difficult reflection in powder on piece, i.e. the segment beam not in conjunction with the yellow fluorescent powder of powder on piece, thus
Cause the blue light beyond the emerging beam range to be directly projeced into the external world, causes scattered light beam more, light-out effect is poor.This skill
Art scheme on laser connecting plate due to being provided with light through-hole, and light through-hole limits the diameter range of emerging beam out, thus
