Take public place such as bright etc. into consideration, can will be also easy to produce heat and powered light source is placed on safe and easy-maintaining place, photoelectricity
Separation reduces the difficulty of construction such as electric leakage, explosion-proof, reduces production cost.
The existing collimation coupled system for optical fibre illumination, such as Application No. CN201710079504.0 patent, one
Simple lens collimation coupled system of the kind for optical fibre illumination field, including LED chip, coupled lens, optical fiber, LED chip are sent
Light by coupled lens collimation enter optical fiber, the central axis of LED chip, coupled lens and optical fiber is in same axis, LED core
Piece is located at the front focus of coupled lens；The light-emitting area of LED chip is centrosymmetric and area is 0.36~2.25mm2, and coupling is saturating
It is in nearly hemisphere lens substantially symmetrical about its central axis that mirror, which is, including close to sources face and remote surface of light source, close to sources face are that radius of curvature is more than
15mm sphere is aspherical, and remote surface of light source is sphere or aspherical of the radius between 1~1.35mm；The front focal length of lens from
For 0.1~0.3mm, center thickness is 0.7~1.2mm；Lens use solid material system of the refractive index between 1.6~1.85
Into.Although this invention is simple in construction, production cost is low, and coupling efficiency is higher, because optical fiber and lens distance closely cause excessively
Heat sinking function is very poor, influences the service life of optical fiber because local temperature is too high, while install because the setting for crossing multi-parameter needs
Want the correspondence of focal length so that packaging efficiency is low.
In a word, the collimation coupled system of existing optical fibre illumination because the reason for its structure there is heat sinking function it is poor, make
With short life, the defects of causing packaging efficiency low cumbersome for installation.
Utility model content
The purpose of this utility model, just it is to provide a kind of collimation coupled system installed and be simply to optical fibre illumination, it
Not only there is splendid heat sinking function, and packaging efficiency is very high, while coupling efficiency is improved up to 25%.
The purpose of this utility model realizes that it includes LED light source, collimater, optical fiber by such technical scheme
Seat, optical fiber head, clamping joint, seal, optical fiber fixing nut and optical fiber, LED light source is in collimater, collimater and fiber bench pair
It should coordinate, optical fiber head is fixed in clamping joint, and fiber bench and clamping joint Corresponding matching, seal is in clamping joint, and optical fiber is successively
It is corresponding with LED light source through optical fiber fixing nut, clamping joint, optical fiber head, fiber bench, collimater, optical fiber fixing nut and clamping
Head is fitted close fixed optical fiber, and collimater is coated with aluminium lamination, space is provided between optical fiber and LED light source.
In the utility model, collimater is coated with aluminium lamination, and its surface uses vacuum aluminium plating process, reflecting rate >=93%, reduces
The light loss that LED light source goes out；Space is provided between optical fiber and LED light source, optical fiber head is avoided and is directly contacted with LED light source, is led to
Crossing cross-ventilation reduces the temperature of light source, optical fiber head.
By adopting the above-described technical solution, the utility model has the following advantages：It is easy for installation, not only with splendid
Heat sinking function, and packaging efficiency is very high, while improves coupling efficiency up to 25%.
