Problems solved by technology

At present, the line light sources used by line array image sensors at home and abroad include monochromatic line light sources, which can achieve illumination lights at different incident angles through installation and adjustment, but the disadvantage is that they cannot provide adjustable illumination lights of different wavelengths; in addition, there are The disadvantage of multi-color circular and rectangular surface light sources with fixed incident angles is that they cannot provide adjustable illumination light with different incident angles.

Embodiment

[0034] The structure diagram of LED multi-color line light source of the present invention is as follows figure 1 As shown, there are LEDs of several colors, and the LEDs of the same color are divided into several columns and arranged at equal intervals on the semi-cylindrical surface of the bracket (1). The extension line passes through the center of the semi-cylindrical surface of the support (1) and overlaps with the radial direction of the semi-cylindrical surface of the support (1).

[0035] The above-mentioned LEDs include three colors. The LEDs of the same color are divided into two rows and arranged at equal intervals on the semi-cylindrical surface of the bracket (1). The LEDs of the three colors are arranged in six rows, and the two rows of LEDs of the same color are staggered by half spacing. In this embodiment, the above-mentioned LEDs include three colors: a blue LED row (2), a green LED row (3), and a red LED row (4).

Abstract

The invention is linear multicolour lighting source required by obtaining image signal and providing scan image for linear array image sensor and prodn. technology. It consists of LEDs with different colour, they are divided to several rows with equally space according to colour and are arranged on cylinder surface of frame, two rows of LED with same colour are staggered in one-seconds space, extending line of optic axis of LED is coincided with radial direction of cylinder surface of frame through the centre of a circle of it. By the invention, the LED multicolour light source not only has suitable and uniform light intensity in scanning line, but also can provides adjustable lighting source with different wave length and incidence angle.

Description

1. Technical field: [0001] The invention relates to a linear multi-color illumination light source and a manufacturing process thereof required for providing scanning images and acquiring image signals for a linear array image sensor. The invention relates to an innovative technology of a line light source used in a line array image sensor and a manufacturing process thereof. 2. Background technology: [0002] At present, image sensors are divided into two categories according to their structures, namely area array image sensors and line array image sensors. Line array image sensors have many advantages over area array image sensors in the detection of high precision, high resolution, large format and moving images, so they are widely used. Due to the high-speed and high-precision image acquisition, the surface materials of different measured objects have different reflection coefficients for different wavelengths of illumination light, and different measured objects have d...
