Abstract
The invention discloses a kind of LED light powered lighting arrangements of the linear CCD using shadowless lamp principle：Installing plate with a rectangular band radian, on installing plate dispersion several lighting devices are installed, the lighting device has cooling fin, and cooling fin is fixedly mounted on installation back, several LED light are equipped on installing plate front.The present invention is mounted on arc substrate, is made of multiple LED light equidistant side by side, and the light path superposition composition linear light sorurce that multiple LED are generated ensure that the consistency of the lighting source of line array CCD, make CCD acquisition signals more accurate；Installation base plate is conducive to heat dissipation, while cooling fin comes into full contact with installation base plate, realizes rapid cooling, effectively extends the service life of LED light；Using light source little power consumption of the LED linear light source that LED combination forms than fluorescent lamp, brightness is high.The generation of shade can be effectively avoided according to the light source that a determining deviation and angle are installed using shadowless lamp principle.
Description
Technical field：
The present invention relates to field of color sorter, the LED light source lighting of more particularly to a kind of linear CCD using shadowless lamp principle fills
It puts.
Background technology：
At present the general lighting source of line array CCD be fluorescent lamp, due to fluorescent light source there are light source consistency it is poor the problem of, cause
Make the need of work that can not meet line array CCD；And in order to solve this problem, simple increase fluorescent lamp quantity, which is still not achieved, to disappear
Except the uniform poor purpose of both ends light source；It on the other hand, will in order to reach the illumination of line array CCD since daylight lamp efficiency is low
It asks, high-power fluorescent lamp can only be selected, high-power fluorescent lamp expends a large amount of electric energy, and fluorescent lamp is put down with fuel factor
Equal service life only has 5000-10000h, and service life is short.
In light source consistency this performance indicator, LED have the characteristics that it is more preferable than fluorescent lamp, meanwhile, LED, which shines, to be produced
Heat amount and energy loss are also smaller than fluorescent lamp more, are handled by substrate and radiating element, heat dissipation problem is properly settled.
In order to generate the consistency light source of high brightness, multiple independent LED light emitting device are pressed parallel fashion permutation and combination by LED light source,
The brightness condition being finally reached required by line array CCD.LED average lives are 50000-100000h simultaneously, and LED is used
Long lifespan reduces use cost.
On certain high-end types, the illumination that single source generates is likely to form shade in certain angles, for material
Identification has a great impact, therefore imagines and set light source according to the principle of Medical shadowless lamp.
Invention content：
The present invention is to solve the above problems, provide that a kind of light source consistency is good, brightness is high, service life is long, little power consumption and does not have
The LED light powered lighting arrangement of the linear CCD using shadowless lamp principle of shade.
The technical solution adopted by the present invention is：
A kind of LED light powered lighting arrangement of linear CCD using shadowless lamp principle：Installing plate with a rectangular band radian, peace
Dispersion is equipped with several lighting devices in loading board, and the lighting device has cooling fin, and cooling fin is fixedly mounted on installation backboard
Face is equipped with several LED light on installing plate front.
The lighting device, LED light N（N≥1）A, N number of LED light is arranged side by side equidistant to be mounted on installation base plate.
The installing plate welds or fixes with fixing device to form close connection with cooling fin, and the material of installing plate is light
Matter height heat dissipation aluminium.
Compared with prior art, the beneficial effects of the present invention are：
The present invention is mounted on arc substrate, is made of multiple LED light equidistant side by side, the light path superposition group that multiple LED are generated
Linear light source ensure that the consistency of the lighting source of line array CCD, make CCD acquisition signals more accurate；Installation base plate is conducive to
Heat dissipation, while cooling fin comes into full contact with installation base plate, realizes rapid cooling, effectively extends the service life of LED light；It uses
The LED linear light source that LED combination forms is than the light source little power consumption of fluorescent lamp, brightness height.Using shadowless lamp principle according between certain
The generation of shade can be effectively avoided away from the light source installed with angle.
Description of the drawings：
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the lighting device schematic diagram of the present invention.
In figure：1st, LED light, 2, installation base plate, 3, cooling fin.
Specific embodiment：
Below in conjunction with the accompanying drawings, the present invention is described in further detail by embodiment：
A kind of LED light powered lighting arrangement of linear CCD using shadowless lamp principle as depicted：With a rectangular band radian
Installing plate 1, on installing plate 1 dispersion several lighting devices are installed, the lighting device has cooling fin 2, and cooling fin 2 fixes peace
Mounted in 1 back side of installing plate, several LED light 3 are installed on 1 front of installing plate.Its LED light of lighting device is N（N≥1）It is a, it is N number of
LED light is arranged side by side equidistant to be mounted on installation base plate.Installing plate welds or fixes with fixing device to be formed closely with cooling fin
Connection, the material of installing plate is lightweight height heat dissipation aluminium.
Embodiment of the present invention is only the description carried out to the preferred embodiment of the present invention, not to the present invention
Conception and scope is defined, and under the premise of design philosophy of the present invention is not departed from, engineers and technicians are to this hair in this field
The all variations and modifications that bright technical solution is made should all fall into protection scope of the present invention, the claimed skill of the present invention
Art content has all been recorded in detail in the claims.
