A LED light is shown as a LED light in Fig. 1, is also possible to 4 or more the LED light equally arranged, this field skill
Art personnel can be arranged according to the actual situation, not affect the implementation of the utility model.
In the present embodiment, radiator 30 is radiator fan, is also possible to other heat dissipation equipments such as water-cooled module, not
Influence the implementation of the utility model.
Whole reflector 40 is in hollow inverted trapezoidal prism-frustum-shaped wide at the top and narrow at the bottom, and bottom connects light supply apparatus 20, top connection
Display device 10 specifically can be such that three closely connects by modes such as screws.Hollow space is passed through for light, inner wall conduct
Reflective surface, the light for issuing luminous 21 edge of lamp group are reflected, to achieve the effect that concentrate light source.
In the present embodiment, the inner wall reflective surface of reflector 40 is made of 8K mirror face stainless steel material.Currently, on the market
Common mirror face stainless steel is divided into tri- kinds of 6K, 8K, 10K.8K is fine grinding, to the light reflection efficiency of 405nm wavelength 90% with
On, it can reach preferable reflecting effect.
To reach optimal reflecting effect, found according to the light source characteristic, the water of reflector 40 side and light supply apparatus 20
When the angle of plane is 60 ° -70 °, reflecting effect is best.Meanwhile reflector 40 is arranged according to the size of light supply apparatus 20
43 size of slot, and slot 43 is smaller, reflecting effect is better, therefore can be set as in the same size with luminous lamp group.With this two
Based on, 44 size of wide opening is determined further according to the size of perspective plane (12 bottom surface light-receiving surface of display screen), and wide opening 44 is smaller, instead
It is better to penetrate effect, therefore can be set as in the same size with perspective plane.Finally by the optimum height that can be calculated reflector 40, into
And the reflector 40 for being optimal reflecting effect is made.In the present embodiment, 40 side of reflector and 20 horizontal plane of light supply apparatus
Angle be set as 66 °.
Again as shown in Figure 2 and Figure 3, the slot 43 of cover hits exactly the luminous lamp group 21 for covering light supply apparatus 20, i.e. slot 43
Central point is Chong Die with the central point of luminous lamp group 21.The display screen 12 of the 44 face display device 10 of wide opening of cover, i.e. wide opening 44
Central point it is Chong Die with the central point of display screen 12, mention the light intensity for being irradiated to 12 bottom surface of display screen and the uniformity
It is high.
In addition, in the present embodiment, reflector 40 is truncated rectangular pyramids shape, it is also designed to round terrace with edge, when perspective plane is circle
When shape, reflector 40 can be accordingly changed to round terrace edge shape, i.e. slot 43 and wide opening 44 is all circle.
Again as shown in Figure 4, Figure 5, specifically, the reflector 40 of the present embodiment includes three folded plates 41 and backboard 42, wherein three
Folded plate 41 includes left and right folding face 412 and middle folding face 411, is inverted trapezoidal wide at the top and narrow at the bottom.The top sides edge of middle folding face 411 is set
There is the first interface 413 for connecting with display device 10.The side of left and right folding face 412 along be respectively provided with for backboard 42
Second interface 414 of connection, bottom edge are respectively provided with the auricle 415 for connecting with light supply apparatus 30.
Backboard 42 is also inverted trapezoidal wide at the top and narrow at the bottom, and height is consistent with three folded plates 41, and 421 top sides of plate body are along equipped with use
In the third interface 422 being connect with display device 10,421 left and right sides edge of the plate body left and right folding face with three folded plates 41 respectively
412 the second interface 414 connection, is additionally provided with notch 423 in 421 bottom edge of plate body, passes through electric wire to light supply apparatus 20
It is powered.
Specifically, the first interface 413, the second interface 414, third interface 422 and auricle 415 can be with respect to cover courts
It is folded outward or towards infolding, does not affect the implementation of the utility model, it is as shown in the figure to be folded outward for court.
In addition, in the present embodiment, the first interface 413, the second interface 414, third interface 422 are all strip
Shape, front and back are designed with location hole, to fixed screw.By three folded plates 41 and 42 Butt Assembling of backboard it is good after, then reflector is installed
40, when installation, first auricle 415 is fixed by screws on the radiating gasket 23 of power supply device 20, then by the first interface 413
It is fixed by screws on the bottom surface of fixed plate 11 of display device 10 with third interface 422.
Further to make three folded plates 41 and backboard 42 fixedly more firm, more closely, location hole is first passed through by front and back
After two parts accurately dock, welding procedure is recycled, the second interface 414 of left and right two and the two sides edge of backboard 42 are welded
On, to complete the processing and fabricating of reflector 40.
Again as shown in Figure 1, light dissipates injection from point light source, is radiated at aobvious after opening power supply to the energization of lamp group 21 that shines
On the bottom surface light-receiving surface of display screen 12, after wherein the light of marginal portion is radiated on the mirror surface of stainless steel mirror reflector 40, quilt
It is reflected into the edge position of light-receiving surface, to enhance the intensity of illumination of edge position, makes light-receiving surface various pieces
Light intensity it is more uniform.
As shown in fig. 6, being the display screen light distribution area schematic of the present embodiment.Display screen 12 is pressed to the light of light-receiving surface
Potent fruit is divided into 5 regions from center to edge, and central area is the maximum region 1 of intensity of illumination, more strong by edge illumination
Degree gradually decreases, minimum to 5 intensity of region.
As shown in fig. 7, curve is more precipitous when not installing reflector 40 additional, light intensity is from center to edge in obvious
Reducing tendency.After installing reflector 40 additional, the light of edge part can be reflected, be irradiated to 12 light-receiving surface of display screen
Edge position, to enhance the intensity of illumination of edge position, therefore, light distribution at this time more uniformly,
The experimental results showed that the reflector 40 can improve 70% or more uniform intensity degree.
In conclusion the utility model compensates the light intensity of edge by inverted trapezoidal prism-frustum-shaped reflector reflection light,
Make illumination of the display screen bottom surface light-receiving surface each section by even intensity, reach model level in print procedure and solidify uniformly,
Same level each section hardness is identical, to improve printing precision and printing effect.
It is above to lift preferred embodiment, the purpose of this utility model, technical solution and advantage have been carried out further specifically
It is bright, it should be understood that the above is only the preferred embodiment of the utility model only, it is practical not new to limit this
Type, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of utility model, the interest field that the utility model is advocated should be to be described in utility model application range
Standard, not just the above examples.
