Description

Liquid circulation lamp assembly and cooling and circulation system of the lamp assembly having the same {Lamp assembly and lamp cooling and circulation system with the same}

The present invention relates to a liquid circulation lamp assembly and a cooling and circulation system for the lamp assembly including the same, and more specifically, to prevent water leakage in a near-infrared emitting lamp in a simple manner even without performing bonding work as before. It relates to a liquid circulation lamp assembly and a cooling and circulation system for the lamp assembly equipped with the same, which can perform maintenance work easily.

Far-infrared and near-infrared rays are infrared rays that are close to the sun's radiant heat and are short-wavelength rays harmful to the human body that do not heat the air but only heat objects through which heat is transmitted. The wavelengths are longer than visible rays, their energy is lower, and they cannot be absorbed by objects. In this case, it has the property of being converted into heat.

When these infrared rays are projected into the human body, they are widely used in infrared treatment devices that can treat affected areas such as muscles or wounds using near-infrared rays irradiated from an infrared lamp, using the property of penetrating deeply into the human body and being converted into heat.

However, conventional near-infrared therapy devices mainly use asbestos around the heating element to block the high heat generated during heating, so when used for a long time, asbestos powder is released, which is not only harmful to the human body but also pollutes the environment.

For example, in Korean Patent Publication No. 10-2010-0039317, there is provided a thermotherapy device that irradiates far-infrared rays, comprising: a housing having an opening formed on one side; an infrared lamp seated inside the opening of the housing and emitting infrared rays; a TDP plate that radiates specific radio waves from the inside of the infrared lamp to the opening; An infrared TDP thermal therapy device has been published, which is seated inside the opening and consists of a radiation plate formed with a curved surface so that infrared rays emitted from the infrared lamp inside the TDP diffuse into the opening.

However, the above-mentioned infrared TDP thermal therapy device is configured to cool only through the cooling cover located on the rear of the housing, so the cooling efficiency is significantly reduced, and it is difficult to control the temperature of the lamp and check the lamp life time. There is a problem.

Accordingly, in order to solve this problem, the present applicant has applied for and received registration at the Korean Intellectual Property Office under Application No. 10-2019-0060608 for ‘liquid circulation lamp assembly cooling and circulation system.’

According to the technology in the above document, the brightness ratio of the liquid circulation lamp assembly is adjusted, supply and circulation are performed according to the level of the coolant to control the high temperature heat emitted from the lamp at a constant level, and at the same time, the liquid circulation lamp assembly is supplied and circulated. It can be controlled to adjust the temperature according to the installation location of the lamp assembly.

Meanwhile, as mentioned above, in order to properly provide the effect of near-infrared rays in a treatment device, etc., a liquid circulating lamp assembly that performs the corresponding function, that is, the function of emitting near-infrared rays, is required.

The liquid circulating lamp assembly includes a near-infrared emitting lamp that performs a near-infrared emitting function. Near-infrared emitting lamps have a structure in which water circulates internally for cooling, and since water should not leak, the end cap must be bonded.

However, if bonding work is performed to prevent leakage of near-infrared ray-emitting lamps, the work is not easy, which not only lowers work efficiency but also makes maintenance work difficult, raising the need to develop technology to supplement this.

In the past, water heated by cooling the liquid circulation lamp assembly 120, for example, water above 50°C, was discarded and refilled with new water, so chemical components, such as iron, in the newly supplied water, that is, tap water, were oxidized. There was a problem of deteriorating performance by damaging or adsorbing various parts such as pipes that make up the system.

In addition, the existing system required continuous supply of tap water, which was not only cost-effective and environmentally friendly, but also difficult to install in existing offices.
