Description

Technical Field

[0001] The utility model relates to the technical field of light bath products, in particular to a portable light bath instrument. Background Art

[0002] Light baths use light emitting diode (LED) devices to generate light of different wavelengths to treat diseases. Red light bath therapy (RLT) refers to a method that uses red light with a wavelength of 640nm to 660nm to treat various diseases and can produce health benefits for different parts of the body. Red light bath therapy is also called low-intensity laser bath therapy (LLLT), low-power laser bath therapy (LPLT) or photobiomodulation (PBM). It is a natural, non-invasive treatment method. Modern medical research has confirmed that red light can produce photochemical and photobiological effects in human tissues, increase cell energy, and has significant effects in enhancing human immunity, promoting blood circulation, eliminating inflammation, improving bone, joint, and muscle pain, accelerating wound healing, improving sleep, alleviating depression, and anti-aging and wrinkle removal. Red, blue and yellow light bath equipment has been widely used in hospital departments such as dermatology, dentistry, gynecology and orthopedics. In recent years, light bath equipment is no longer limited to use in professional medical institutions, and more and more of them have entered families and become people's favorite home health products.

[0003] The light bathing equipment used by professional medical institutions is relatively large and expensive, which is not suitable for home use and is not easy to carry. Existing small light bathing equipment generally uses a plastic shell and back panel, which has poor heat conduction and heat dissipation effects, and has no high temperature protection device or alarm device. When the equipment is used for a long time, a large amount of heat will accumulate inside the light bathing equipment, causing the light board and control board to be in a high temperature state for a long time, which is easy to cause equipment failure and greatly shorten the service life of the product. In addition, the existing small light bathing equipment has a relatively complex structure, many assembly steps, and low production efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a light bathing device that is small in size, easy to carry, has good heat dissipation performance, and has a high temperature protection function, so that the light bathing device can work stably for a long time and has a long service life. To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A portable light bath instrument, characterized in that it includes a rectangular frame, a prism plate, an LED light board and a back plate, wherein the inner side of the rectangular frame is provided with an annular front baffle and a rear baffle which are arranged in parallel and spaced apart and extend inward, the prism plate is located on the inner side of the rectangular frame and the front side of the front baffle, the back plate is located on the inner side of the rectangular frame and the rear side of the rear baffle, the LED light board is arranged between the prism plate and the back plate, and the rectangular frame, the front baffle and the rear baffle are integrally formed.

[0006] Preferably, the rectangular frame, the front baffle and the rear baffle are made of aluminum alloy, the corners of the rectangular frame are arc-shaped, and the front baffle and the rear baffle are disconnected at the corners of the rectangular frame.

[0007] Preferably, the prism plate includes a flat plate portion and a plurality of convex conical prism portions provided on the back side of the flat plate portion, and the tops of the plurality of prism portions are each provided with a concave portion.

[0008] Preferably, the LED light board includes an aluminum substrate and an LED light group, wherein the LED light group is disposed on the aluminum substrate, and a plurality of light-emitting elements of the LED light group are embedded in recessed portions at the tops of the plurality of prism portions.

[0009] Preferably, the flat plate portion protrudes outward from the plane formed by the rectangular frame.

[0010] Preferably, the flat plate portion is set to be opaque or translucent, and the conical prism portion is set to be transparent.

[0011] Preferably, an opaque annular shielding layer is provided on the edge of the back side of the flat plate portion, and the shielding layer comprises at least one of ink, spray paint, plastic film or metal film.

[0012] Preferably, a raised hollow second screw column is provided in the middle of the back side of the prism plate, the aluminum base plate is provided with two through holes, the screw column is passed through the second through holes, the back plate is provided with a third through hole, and the back plate and the second screw column cooperate by passing through the third through hole and the screw column to fix the back plate to the inner side of the rectangular frame.

[0013] Preferably, a control board is also included, which is arranged between the aluminum substrate and the back plate. The control board is provided with a timing module and a temperature control module. The temperature sensing probe of the temperature control module is used to detect the temperature of the LED light board and the control board.

[0014] Preferably, the temperature control module is provided with a first preset temperature and a second preset temperature higher than the first preset temperature. When the temperature control module detects that the temperature of the LED light board and / or the control board reaches the first preset temperature, the temperature control module reduces the power of the LED light group. When the temperature control module detects that the temperature of the LED light board and / or the control board reaches the second preset temperature, the power supply of the LED light group is turned off.

[0015] The beneficial effects of the above technical solution are: the rectangular frame, front baffle, rear baffle and back plate are all made of aluminum alloy with good thermal conductivity, the aluminum substrate of the light board is against the front baffle, and the back plate is against the rear baffle. The heat generated by the LED light group can be quickly dissipated through the aluminum substrate front baffle, rear baffle and the back plate with a larger area, which can effectively reduce the operating temperature of the light bathing equipment and prevent the light bathing equipment from causing equipment failure and damage due to excessive temperature. Secondly, the temperature control module detects the temperature of the LED light board and / or control board in real time when the light bathing equipment is running. When the temperature of the aluminum substrate exceeds the preset temperature, the power is reduced or the light board power supply is disconnected, which can prevent the equipment from being damaged or shortened due to high temperature. Third, the prism plate and the back plate are fixed in the rectangular frame by the screw column and screws in the middle of the prism plate. In this way, in order to reduce the exposure of the screws on the back plate, a smaller label can be used to cover the screw holes, making the product more concise and beautiful. Fourth, an opaque annular shielding layer is set on the edge of the back of the flat plate to completely cover the part of the product that affects the appearance. BRIEF DESCRIPTION OF THE DRAWINGS
