Problems solved by technology

[0004] Traditional LED lamps use brightness control for all LEDs. They cannot choose to control the angle of light irradiation, and cannot focus on observing a certain feature of an object, so that the observation of objects such as plastics and hardware is not clear, resulting in error in measurement accuracy

Abstract

The invention relates to a regulation and control method of a program control lamp source and provides a program control lamp source regulation method capable of selecting the angle of light irradiation and clearly and intensively observing a certain characteristic of an object. The invention adopts the technical scheme that the program control lamp source comprises a luminous body, a lamp holder and a control circuit board, wherein the luminous body is an LED lamp; the lamp holder is of a colloid bowl-shaped structure; the outside of the bowl-shaped structure is provided with a small convection hole communicated with the interior, and an inner groove of the colloid bowl-shaped structure is embedded with at least one layer of annular circuit board capable of controlling different areas according to an independent program along a set angle; the LED lamp is fixed to and electrically connected with the circuit boards; and a USB (Universal Serial Bus) interface communicated with a PC (Personable Computer) is electrically connected with the circuit boards. The invention can be used for selectively controlling the angle of light irradiation, observing intensively a certain characteristic of an object and clearly observing objects of plastic, hardware, and the like so as to improve the measurement precision.

Description

technical field [0001] The invention relates to a program-controlled light source, in particular to a program-controlled light source and an adjustment control method thereof. It is mainly used in the field of precision inspection based on machine vision. It can make corresponding choices for different materials such as reflectivity, contour curvature radius, and detection target features, which greatly enhances the accuracy of the machine and the accurate recognition of objects. Background technique [0002] LED is a light-emitting diode, which has the characteristics of small size, low power consumption, long service life, high brightness, low heat, environmental protection, and durability, so it is widely used. Most of the traditional dimming methods of LED lamps adopt analog adjustment mode, and the purpose of adjusting the brightness of LED lamps is achieved by controlling the magnitude of the current flowing through the LED. Due to this control method, the LED lamp is...
