Description
技术领域 technical field
本发明涉及一种光固化装置，具体是一种用于固化机光源的安全供电系统，属于固化设备技术领域。 The invention relates to a light curing device, in particular to a safe power supply system for a light source of a curing machine, and belongs to the technical field of curing equipment.
背景技术 Background technique
光固化机(牙科光敏树脂固化机)是牙医帮病人修复牙齿时，用来固化光敏树脂材料的机器。LED光固化机由光源部分和控制电路组成。产品适用范围：对树脂材料进行固化，供中腔科作修复牙齿用。 Light curing machine (dental photosensitive resin curing machine) is a machine used by dentists to cure photosensitive resin materials when helping patients restore teeth. The LED light curing machine is composed of a light source part and a control circuit. Scope of application of the product: curing the resin material, used for tooth restoration in the cavity department.
牙科通过主机上的LED灯发出的光辐射，能够让光固化树脂在短时间内迅速并有效的聚合固化。现有的光固化机工作时的供电方式有两种：一是直接由外部的牙椅或电网电源供电，二是通过在主机上内置高容量的锂离子电池供电。锂离子电池供电的方式相较于牙椅或电网电源供电方法而言，没有电线的限制，移动和使用方便，且一次充满电后的工作时间长(200次以上)，因而在便携式的光固化机中获得了越来越广泛的使用。然而，通过锂电池供电的方式虽然使用方便，一次充满电后的工作时间长(200次以上)，但锂电池每次充电的时间较长，通常需要2-3个小时，且锂电池的使用寿命有限。此外，由于锂电池在满电和无电状态下的输出电压差别是非常大，因而光固化机的LED灯在工作时难以保持一个稳定的光强输出，进而使得光固化树脂出现固化程度不均或固化速度过慢的现象，而极大地影响了光固化树脂的聚合固化效果。 Dentistry uses the light radiation emitted by the LED lamp on the main unit to allow the light-curing resin to polymerize and cure quickly and effectively in a short period of time. There are two power supply modes for existing light curing machines: one is directly powered by an external dental chair or grid power supply, and the other is powered by a built-in high-capacity lithium-ion battery on the host. Compared with dental chairs or grid power supply methods, the lithium-ion battery power supply method has no restrictions on wires, is convenient to move and use, and has a long working time (more than 200 times) after a full charge, so it is popular in portable light curing machine has been used more and more widely. However, although the lithium battery power supply method is convenient to use and has a long working time (more than 200 times) after a full charge, the lithium battery takes a long time to charge each time, usually 2-3 hours, and the use of lithium batteries Life is limited. In addition, since the output voltage of the lithium battery is very different between full charge and no charge, it is difficult for the LED lamp of the light curing machine to maintain a stable light intensity output during operation, which makes the curing degree of the light curing resin uneven. Or the phenomenon that the curing speed is too slow, which greatly affects the polymerization and curing effect of the photocurable resin.
