Description
Technical field
The present invention relates to light source and lighting technical fields, more particularly to a kind of large area array LED light for schlieren illumination
Source system.
Background technique
In schlieren trial, light source first passes around amasthenic lens and expands for providing optical path illumination, the light that light source issues, so
It is afterwards collimated light beam by collimation principal reflection mirror collimation, light beam is reflected into imaging point through schlieren principal reflection mirror behind test section
System forms schlieren image after imaged system processing.
Mainly index is paid attention in terms of the illuminance of imaging system, reliability, colour rendering three for the selection of light source.
The light-emitting surface of traditional tungsten halogen lamp is that an approximate area source is coiled by filament, can be clearly visible at projection to slit
Filament picture, and tungsten halogen lamp colour developing is milky, schlieren image is partially yellow.
In addition, a large amount of heat is generated in tungsten halogen lamp luminescence process, and it is poor due to radiating, to substantially reduce the use of light source
Service life.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of large area array LED lights for schlieren illumination
Source system, brightness which solve existing halogen tungsten lamp light sources in carrying out schlieren lighting process is low, poor, the schlieren image of colour developing Huang partially and
The problem of heat dissipation effect difference.
The specific technical solution of the present invention is:
The present invention provides a kind of large area array LED light source systems for schlieren illumination, it is characterised in that: including large area array
LED light, flange shell, power interface, heat-conducting copper pipe and radiator；
Large area array LED is fixed on flange housing center, and is located at the front of radiator；
Power interface is mounted on radiator rear end；
One end of heat-conducting copper pipe and flange cage connection, the other end is through setting in radiator.
Further, above-mentioned large area array LED is the hexagon inscribed circle battle array of 61 LED light composition.
Further, the design parameter of each above-mentioned LED light is: light emitting region be Φ 12mm, luminous power 40W,
Luminous flux is up to 4000lm, luminous efficiency 100lm/W.
Further, the radiator includes cooling fin and at least one wind for being close to the installation of cooling fin heat dissipation region
Fan；
Further, the cooling fin is arranged side by side using multilayered fold fin, whole in rectangular configuration.
Further, the gap in the cooling fin between every layer of fold fin is 10mm.
Further, the power interface is followed by DC power supply
Further, the fan is two.
Beneficial effects of the present invention are as follows:
One, it present invention employs the illumination of large area array LED schlieren, compared to traditional tungsten halogen lamp schlieren light source, can obtain highlighted
It spends, develop the color, the schlieren image of uniform-illumination, and LED schlieren illumination gained schlieren image background is that daylight is white, is more suitable line
Shadow illumination.
Two, the present invention use heat-conducting copper pipe, cooling fin and the integrated heat dissipation design of fan, effectively solve system overheat by
Damage problem improves the service life of light source.
Three, cooling fin is substantially increased heat dissipation area, is improved heat dissipation using the design of multilayered fold fin in the present invention
Efficiency.
Four, the present invention is radiated using two fans, the effect for improving heat dissipation further.
Five, the present invention uses DC power supply for the power supply of large area array LED light, can directly adjust large area array LED illumination brightness, grasp
Make simple.

Fig. 2 is side view of the invention；
Fig. 3 is the structural schematic diagram of large area array LED.
Appended drawing reference is as follows:
1- large area array LED light, 2- flange shell, 3- heat-conducting copper pipe, 4- cooling fin, 5- fan, 6- power interface.
Specific embodiment
For the design feature and concrete form that the present invention will be described in detail, now gives an actual example and attached drawing is cooperated to be illustrated.
As shown in Figure 1, a kind of large area array LED light source system for schlieren illumination, it is characterised in that: including large area array
LED light 1, flange shell 2, power interface 6, heat-conducting copper pipe 3 and radiator；
In the present embodiment, radiator be by include cooling fin 4 and be close to cooling fin heat dissipation region (cooling fin is formed
Upper and lower two planes) installation at least one fan 5 composition (in this example fan use two).Cooling fin 4 uses multilayered fold
Fin is arranged side by side, and cooling fin 4 is whole in rectangular configuration.
6 external direct current power supply of power interface.
Each section connection structure of the light source is as follows:
Large area array LED light 1 is fixed on 2 center of flange shell, is followed by DC power supply to large area array LED using power interface 6
1 power supply, 3 one end of heat-conducting copper pipe are arranged on flange shell, and other end runs through (through direction is from front to back) all heat dissipations
Piece 4, two fans 5 are respectively arranged in 4 two sides of cooling fin.
Radiating principle: heat is transferred to each piece by flange shell, heat-conducting copper pipe during the work time by large area array LED
On cooling fin, then conduct heat in outside air via two fans.
Wherein, large area array LED is the hexagon inscribed circle battle array of 61 LED light composition.The parameter of each LED light is such as
Under:
Light emitting region is Φ 12mm, luminous power 40W, and luminous flux is up to 4000lm, luminous efficiency 100lm/W.
