Description

Improved ultraviolet light source machine

Technical field

The utility model relates to a kind of improved ultraviolet light source machine, especially a kind of light source machine that can produce high intensity ultraviolet linear light (UV) of finger is constructed, wherein light source can be divided into several light beam through the optically focused camera lens and can use respectively, thereby can conveniently install beam device, shorten the overall length of beam device, and the service efficiency that improves the UV light beam.

Background technology

The structure of present known UV light source machine (as shown in Figure 5), it comprises support a, shell b, power supply unit c, control circuit board d, radiator fan e, lamp group f, optically focused camera lens g and a beam device h, this lamp group f is through power supply unit c and control circuit board d power supply and when luminous, the light that it sent will focus on through optically focused camera lens g, penetrate the UV light beam forward for use by beam device h.

This known UV light source machine structure, optically focused camera lens g wherein is single-focusing convex lens (as shown in Figure 6), or separately with reflector (being the speculum of the bulb rear side of lamp group among Fig. 5) as focusing on, be sent to a beam device h who mainly forms behind its light source optically focused by optical fiber with lamp group f ejaculation, optical fiber i in this beam device h is divided into several strands, nationality is reached and is separated the purpose of using the UV light beam by the guiding of each strand optical fiber i.

Yet, above-mentioned known light source machine structure, because the focus of optically focused camera lens g is therein on the axle line, so the optical fiber i in the beam device h must be concentrated into a branch of by light source one end fully, the other end just slowly is divided into several strands of optical fiber and extends use, and promptly this known construction has the shortcoming of the UV beam intensity inequality of each strand optical fiber.And if the quality of its optical fiber i belongs to a kind of hard and crisp characteristic, it must not have the situation of minor-circle turn when share split, because of flexibility easily makes optical fiber fracture when excessive.If it is a kind of than soft characteristic that the quality of optical fiber i belongs to, its turning will be easy to generate light leak and reduce light efficiency.

In addition, above-mentioned optical fiber i is necessary to be concentrated earlier to a branch of several bursts of separately uses again, if wherein some optical fiber damages (fractureing), then need put in order group and change, the increase cost.If will overcome fracture problem with light leak of optical fiber, it is crooked slowly that each strand optical fiber i is done, but so will increase the length of entire light device h, is not easy to make and use.

This case designer has and states being configured in when beam split is used of known light source machine in view of this and have great shortcoming, and thinking real has improved necessity, studies intensively, and develops improved ultraviolet light source machine of the present utility model eventually.

Summary of the invention

Problem to be solved in the utility model is: a kind of improved ultraviolet light source machine is provided, the focus ring that its optically focused camera lens has a plural number is established and is arranged in light and moves towards around the center line, be easy to install each strand optical fiber, it is high and dwindle effect such as beam device length to have simple structure, light-conductive rate.And each strand optical fiber can distinctly be changed when if damage is arranged, and reaches the effect of saving the optical fiber cost.

Technical solution of the present utility model is: a kind of improved ultraviolet light source machine, it includes support, shell, power supply unit, control circuit board, radiator fan, lamp group, optically focused camera lens and beam device, this lamp group is through power supply unit and control circuit board power supply, its light will can penetrate linear light beam by beam device through the gathering of optically focused camera lens; Wherein:

The optically focused camera lens of said apparatus in lamp group the place ahead has the less convex lens of a plurality of volumes, these a plurality of convex lens annular arrangements and one-body molded, and it is a multifocal optically focused camera lens.

The utility model has the advantages that:

1, a kind of improved ultraviolet light source machine that the utility model proposes, its lamp group the place ahead is provided with the optically focused camera lens, and this optically focused camera lens is one-body molded with annular arrangement by the less convex lens of a plurality of volumes, i.e. a multifocal optically focused camera lens.It can make things convenient for and effectively distribute light source to several optical fiber beam devices, can improve the conduction efficiency of light.

2, improved ultraviolet light source machine of the present utility model, its each beam device can distinctly be changed, thereby reduce cost if damage is arranged.And the more known beam device length of this beam device is little, has dwindled the volume of single unit system, is convenient to install and use.
