Abstract

The invention discloses an LED imaging light source which comprises an upright and a light source plate fixed at the top of the upright. An LED array is arranged on the front of the light source plate and composed of 25 LEDs which are arranged to be a square array in a five-line five-row manner, and the line pitch is equal to the row pitch; a switch array of the LEDs is correspondingly arranged on the back of the light source plate and composed of 25 button switches which are arranged to be a square array in a five-line five-row manner, the line pitch and the row pitch of the switch array are equal to those of the LED array, and powering on and off of each LED is independently controlled by the corresponding button switch on the back of the LED. The LED imaging light source can be used as a light source, can also be used as an article screen and is simple in structure, convenient to use and conductive to experimental studies on lens imaging laws.

Description

A kind of led array imaging source

Technical field

The present invention relates to a kind of Experiments of Optics light source, be specially a kind of led array imaging source.

Background technology

In the experiment of research lens image formation rule, need to provide the object of imaging.At present, the candle of lighting commonly used perhaps shields as the imaging thing with the thing of Down lamp irradiation with hollow " 1 " font as the imaging thing.During as the imaging thing, candle flame itself has instability with the candle of lighting, and with potential safety hazard, the candle drop is fallen and is difficult to cleaning on the experiment equipment, is difficult to judge the left and right sides position relationship of picture and thing in the experiment.When shielding with " 1 " vee V, imaging thing shape is comparatively single, and is improper if put the position of light source and thing screen, also can directly affect imaging effect.Lack at present preferably solution.

Summary of the invention

The purpose of this invention is to provide and not only can be used as light source, but also can serve as a kind of led array imaging source of picture thing.

In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions: a kind of led array imaging source, comprise vertical rod and be fixed on the light source board at vertical rod top, it is characterized in that: described light source board front is provided with led array, described led array is comprised of 25 LED, be arranged in square formation by the five-element's five row, line-spacing equates with the row distance; Described light source board back side correspondence is provided with the switch arrays of LED, described switch arrays are comprised of 25 pushbutton switches, be arranged in square formation by the five-element five row, line-spacing, row apart from the line-spacing of led array, row apart from equating, each LED passes through pushbutton switch corresponding to its back side and independently controls its on/off.

The present invention is owing to adopting above-mentioned design, can realize following beneficial effect: each LED on the light source board can independently control its break-make by corresponding pushbutton switch, thereby can utilize as required LED to be combined into the imaging thing of various shape, the present invention both can be used as light source, available crop is shielded again, it is simple in structure, and is easy to use, is conducive to the experimental study of lens image formation rule.
