Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as figure 1 As shown, a LED emitting tube testing method, a plurality of standard LED receiving tubes are arranged in the same plane to form a plane of the LED receiving tube, and the LED emitting tube to be tested is arranged outside the plane of the LED receiving tube.

[0028] The number of standard LED receiving tubes set here can be adjusted according to actual needs, and the size of the LED receiving tube plane can also be adjusted according to actual needs. In addition, the setting density of standard LED receiving tubes can be adjusted according to the requirements of test accuracy, which is ea...

Abstract

The invention provides an LED (light-emitting diode) emitting tube and LED receiving tube testing method, which utilizes a standard LED receiving tube for processing and calculating to obtain the maximum emitting light intensity and the lighting angle of a to-be-detected LED emitting tube, and utilizes a standard LED emitting tube for processing and calculating to obtain the maximum receiving light intensity and the receiving light angle of a to-be-detected LED receiving tube. In the whole testing process, expensive testing equipment is unnecessary, and only the standard LED receiving / emitting tubes are necessary to be utilized, so that testing for the to-be-detected LED emitting / receiving tube can be realized. Therefore, the LED emitting tube and LED receiving tube testing method has the advantages of being low in implementation cost, simple in testing process and capable of accurately testing a to-be-detected LED lamp tube.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a testing method for an LED emitting tube and an LED receiving tube. Background technique [0002] The infrared tube touch screen is a touch screen that installs an infrared emitting tube and an infrared receiving tube on two sets of opposite sides of the screen frame, and obtains the coordinate position of the touch point by switching the optical path of the infrared pairing tubes on the two sets of opposite sides. [0003] LED infrared lamps are divided into two types: emission and reception, which are distinguished by light color and dark color, and can also be divided into two types: 850nm and 940nm, which are distinguished by wavelength. This technology can calculate the light intensity and luminous angle of the LED lamp by obtaining the signal value of the LED lamp, so as to distinguish whether it meets the design requirements of 850nm and 940nm. The voltage and current of th...
