Abstract
The utility model relates to an annular LED illuminating plate, which is used for an image analyzer. The annular LED illuminating plate is characterized in that the plate is annular and a plurality of LED mounting holes are arranged on the plate. The annular LED illuminating plate is reasonable in structural design, and the LEDs are arranged annularly, so that uniformity of illumination of a light source to the whole view field is improved greatly and light leakage of a non-irradiation area is reduced.
Description
Technical field
The utility model relates to a kind of annular LED illuminatian plate, is used for the graphical analysis instrument.
Background technology
At present, common LED lighting source on the domestic and international market mostly is the online detection that is used for industrial flow-line, the backlight of display device and the special-purpose import light source of professional instrument and meter.And the led light source that the normal image analytical instrument is used, better performances mostly be foreign vendor's product, price is higher, and can't customize according to actual instructions for use.
The graphical analysis instrument of prior art is the uniformity of illumination with another problem that the LED lighting source exists, and all exists phenomenons such as focal point, hot spot, the ring of light are arranged on the direction of illumination usually, influences the graphical analysis and the processing in later stage.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design is provided, is applicable to the annular LED illuminatian plate of graphical analysis instrument.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of annular LED illuminatian plate, comprise plate body, and it is characterized in that: described plate body has a plurality of LED installing holes for annular on plate body.
The center of LED installing hole described in the utility model is on same circle.
LED installing hole described in the utility model is 12.
The utility model has the screw installing hole on described plate body.
The utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, make LED arrange ringwise, improved the uniformity of light source greatly, reduced the light leakage phenomena of non-irradiation area the illumination of whole visual field.
Description of drawings
Fig. 1 is the Facad structure schematic diagram of the utility model embodiment.
Fig. 2 is the structure schematic diagram of the utility model embodiment.
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1～Fig. 3, the utility model embodiment comprises plate body 1, and plate body 1 is an annular, has 12 LED installing holes 2 on plate body 1.The center of 12 LED installing holes 2 is on same circle.LED installing hole 2 is used to install the LED on the pcb board.
On plate body 1, also have 4 screw installing holes 3, be used for present embodiment is fixed on pcb board.
Can on present embodiment, brush two-sided diffuse reflection coating, both improve the efficient of illumination, guarantee the uniformity of illumination again.
During use, present embodiment is fixed on the pcb board, and each LED on the pcb board is positioned on the corresponding LED installing hole 2.LED arranges ringwise, has improved the uniformity of light source to the illumination of whole visual field greatly, has reduced the light leakage phenomena of non-irradiation area.
