Embodiment 1

[0028] The light intensity of the tricolor LED light source is adjustable from 5mcd to 20mcd. A stroboscopic pulse generator 6 is connected to the electrical circuit of the light source, and the speed range of the stroboscopic light is 2 times / second. The material of the light diffusion sheet 14 is PMMA. The light diffusion sheet 14 is a dual-core cohesive micro-pearl light diffusion sheet, and the microbeads of each light diffusion sheet have two refractive indices to enhance the light mixing effect.

Embodiment 2

[0030] The light intensity of the three-primary-color LED light source is 20mcd-40mcd, which is continuously adjustable. A stroboscopic pulse generator 6 is connected to the electrical circuit of the light source, and the speed range of the stroboscopic light is adjustable: 2 times / second-4 times / second. The material of the light diffusion sheet 14 is PMMA. The light diffusion sheet 14 is a multi-core cohesive micro-pearl diffusion sheet, and the microbeads of each light diffusion sheet have multiple refractive indices to enhance light transmittance and light mixing effect.

Embodiment 3

[0032] The light intensity of the three-primary-color LED light source is 30mcd-60mcd, which is continuously adjustable. A stroboscopic pulse generator 6 is connected to the light dimmer circuit 5 of the light source electrical circuit, and the speed range of the light stroboscopic: 3 times / second. The material of the light diffusion sheet 14 is PMMA. The light diffusion sheet 14 is a dual-core cohesive micro-pearl diffusion sheet, and some of the micro-beads of the light diffusion sheet have two refractive indices to enhance light transmittance and light mixing effect.

Abstract

The invention provides a light-source device for an image-identifying system, which comprises a light-source electrical-apparatus line and a light-source head, wherein R, G and B tricolor LED (Light-Emitting Diode) light sources are generated by the light-source electrical-apparatus line, and in addition, a COM (Component Object Model) is used as a tricolor LED public positive electrode. The light-source head comprises a lamp shell, a positioning part, a pressure cover, a tail cover and sealing glue. A dimmer circuit is connected to the inner part of the light-source electrical-apparatus line, and on one hand, the light intensity of the tricolor LED light sources is changed by changing the current of the dimmer circuit; and on the other hand, after the light intensity of the tricolor LED light sources is respectively changed, different light-emitting intensities in R, G and B colors is obtained to further obtain different synthetic-light colors. A light stroboscopic technology is alsoadopted in the light-source electrical-apparatus line, so that the gray scale of images is improved. The light-emitting end surface of the light-source head is also connected with a light-diffusing piece, so that the light-emitting uniformity is improved. The illuminating-light intensity, the color and the stroboscopic frequency of the light-source device are continuously adjustable, the identifying capability and the identifying effect of an identifying system are improved, compared with a traditional tungsten-filament bulb, the service life can be prolonged by more than 100 times.

Description

technical field [0001] The invention relates to a light source device of an image recognition system in microelectronic production and testing equipment. Background technique [0002] The image recognition system is a commonly used device in automatic production equipment at present. There is a light source in the image recognition system to provide lighting for the camera. Different cameras have different sensitivities to different light intensities and different colors of light, and the reflective effects of the identified objects to different light intensities and different colors of light are also different. Moreover, the recognition effect of constant light lighting is not as good as that of strobe lighting. Therefore, the light intensity, light color, and whether stroboscopic (intermittent light emission) of the light source of the recognition system have a great influence on the image recognition system. [0003] An "image reading device, image reading system, and i...
