Microspur light supplement module with flexible circuit boards

Abstract

A microspur light supplement module with flexible circuit boards is used in cooperation with an optical imaging resolution device, the optical imaging resolution device is provided with a light entrance, and the microspur light supplement module is correspondingly arranged at the light entrance. The microspur light supplement module comprises a sleeve barrel, at least one circuit board component, a set of light emitting component and a set of angle adjusting component, wherein the circuit board component comprises at least one flexible circuit board and multiple composite board areas with hard board gaskets respectively, the circuit board component is arranged on the sleeve barrel in a set mode, the light emitting component comprises multiple light emitting elements which are arranged in the composite board areas respectively and provided with light emitting faces respectively, and the angle adjusting component comprises multiple pivotal pieces which drive the composite board areas to rotate relative to the sleeve barrel in a pivot mode respectively and to adjust the light emitting angles of the light emitting elements.

Description

【Technical field】 [0001] The invention relates to a macro-distance supplementary light module, in particular to a macro-distance supplementary light module with a flexible circuit board. 【Background technique】 [0002] Professionally, macro photography refers to photography with a magnification of one time the size of the real object or greater. In simple terms, it is to compare the real object with its image size on the film or CCD, both of which have exactly the same size. However, the shooting distance is usually only 5 to 8 cm. At such a short distance, if you want to get enough depth of field (the clear range of the image in front and behind the focus point), the aperture must be reduced quite small (f / 16, f / 22 ), and compared with the longer exposure time of ordinary cameras, if the shooting skills are not skilled enough, it is easy to take dim and blurred pictures. In order to solve the above problems, an external fill light device is often used to connect to the fro...

Problems solved by technology

[0003] With the expansion of the macro photography market, manufacturers have developed a variety of macro supplementary light modules, usually a group of supplementary light modules that use light-emitting diodes as artificial light sources in front of the lens, such as figure 1 As shown, the light-emitting diode 92 is welded on the hard circuit board 93, but the lead wire 921 that is fine and has a certain length not only must be installed manually by skilled assemblers, but also is easy to be pulled during the installation process, which increases the difficulty of assembly. , it may also cause poor signal and energy conduction due to slight pulling, and reduce the yield; moreover, each hard circuit board 93 must also be manually screwed to the sleeve 91 with the screws 94 one by one , affecting the output efficiency; what’s more, in order to adjust the fill light angle, the hard circuit board 93 must be rotated frequently, not only the possibility of the lead wire 921 being hooked, but also the lead wire 921 may be bent repeatedly, resulting in poor contact or Internal open circuit, reducing service life and increasing maintenance troubles

[0004] In recent years, in addition to the general and customary uses of macro photography, many special uses have been developed, such as banknote anti-counterfeiting, medical cosmetology, skin diagnosis and treatment, criminal identification, etc., especially in some fields involving fluorescence. Therefore, it is also necessary to Provide short-distance supplementary light modules such as ultraviolet light; on the other hand, a microscope is another image analysis device that will be equipped with a supplementary light module. Microscopic section images are faint
