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 program-controlled lamp source, in particular to a program-controlled lamp source and a control method thereof. The invention provides a program-controlled lamp source, which is capable of selecting lamp illuminating angle and is capable of focusing on a particular feature of an object for clear observation, and a control method thereof. The technical proposal of the invention is that the program-controlled lamp source comprises an illuminant, a lamp holder and a control circuit board, wherein, the illuminant is an LED lamp; the lamp holder has a bowl-shaped rubber structure, the exterior of the bowl-shaped structure is provided with a convection hole communicated with the interior; at least one layer of circular circuit board capable of controlling different areas via independent programs is embedded in a given angle in a groove inside the bowl-shaped rubber structure; the LED light and the circuit board are fixed and connected electrically; a USB interface communicating with a PC is connected electrically with the circuit board. The invention is capable of selecting lamp illuminating angle, is capable of focusing on a particular feature of an object for clear observation, and provides clear observation of plastic and metallic objects, and the like, thus enhancing measurement accuracy.

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...
