Description

Technical Field

[0001] This invention provides an experimental device for LED ultraviolet light degradation, belonging to the field of LED lighting technology. Background Technology

[0002] Existing LED ultraviolet lamp technology is mostly used in disinfection, sterilization, curing, and fluorescence detection, with a smaller portion applied to the degradation and transformation of toxic substances in scientific research experiments. Current LED ultraviolet lamps have the following problems:

[0003] 1. Low light utilization rate: During the emission process of existing LED ultraviolet lamps, some light cannot effectively illuminate the target area due to scattering, reflection and other reasons, resulting in low light utilization rate and serious energy waste.

[0004] 2. Limited effectiveness in degrading toxic substances: In the scientific research field, ultraviolet lamps are used to degrade toxic substances in water, but the existing technology still needs to be improved in terms of processing speed and effectiveness, which limits its application in the field of environmental governance.

[0005] 3. The light source cannot pass through the liquid and cannot be recycled: In laboratory settings, LED UV lamps need to irradiate the liquid inside test tubes, but existing LED UV lamps cannot achieve effective light transmission. Furthermore, excess light cannot be recycled, further reducing luminous efficiency.

[0006] 4. Inadequate optical design: The optical design of existing LED ultraviolet lamps fails to fully consider the loss during light propagation, resulting in low light utilization.

[0007] 5. The radiation effect of ultraviolet lamps is not ideal: In terms of degrading toxic substances, the radiation effect of existing ultraviolet lamps is not good, which makes it difficult to meet the needs of researchers in terms of processing speed and effectiveness. Utility Model Content

[0008] To address the above problems, this utility model aims to provide a novel LED ultraviolet lamp technology. By optimizing optical design, improving the ultraviolet lamp radiation effect, and realizing light source transmission and recycling, it effectively enhances the utilization rate of LED ultraviolet lamps and provides researchers with new solutions in fields such as the degradation of toxic substances.

[0009] The specific technical solution is as follows:

[0010] An experimental device for LED ultraviolet degradation includes an acrylic box with a lid on top. Both the lid and the inner wall of the acrylic box are inlaid with total reflection mirrors, and a cooling fan is provided on the bottom plate.

[0011] The acrylic box contains multiple sets of quartz test tubes, which are embedded in the surface of the heat-insulating light-concentrating sheet. The surface of the quartz test tubes is equipped with a temperature control device.

[0012] The temperature control device is a copper wire wrapped around the surface of a quartz test tube. The wire of the copper wire is connected to a thermistor and an external power supply that controls the heating power of the copper wire.

[0013] Alternatively, the temperature control device may be a double-layer quartz test tube water bath temperature control device or a heated air temperature control device.

[0014] Below the heat-insulating light-concentrating sheet is an acrylic panel, in which multiple LED ultraviolet lamp beads are embedded; the lamp beads operate in parallel.

[0015] A support base is also provided below the base plate.

[0016] The beneficial effects of the technical solution of this utility model

[0017] 1. It can increase the utilization rate of LED UV lamps by more than 20%;

[0018] 2. This provides researchers with a new approach to studying how ultraviolet lamps can degrade toxic substances faster and better within the same time frame;

[0019] 3. The light emitted by LEDs can not only pass through the liquid inside the test tube, but also allow excess light to be reused. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0021] The specific technical solution of this utility model is described in conjunction with the accompanying drawings, such as... Figure 1 As shown, an LED ultraviolet light degradation experimental device includes an acrylic box 2, a lid 1 on the top, total reflection mirrors embedded in the lid 1 and the inner wall of the acrylic box 2, and a cooling fan 6 on the bottom plate.

[0022] The acrylic box 2 contains multiple sets of quartz test tubes 3, which are embedded on the surface of the heat-insulating light-concentrating sheet 4. The surface of the quartz test tube 3 is surrounded by copper wires for heating and temperature control. The wires of the copper wires are connected to thermistors and external power supplies to control the heating power of the copper wires.

[0023] Below the heat-insulating light-concentrating sheet 4 is an acrylic plate, in which multiple LED ultraviolet lamp beads 5 are embedded; the lamp beads operate in parallel.

[0024] A support base 7 is also provided below the base plate.

[0025] Preferably, in this utility model:

[0026] The lid 1 measures 34*34cm, with an acrylic sheet surface and a total reflection mirror embedded on the inside. The lid serves as the sampling inlet.

[0027] The inner surface of the acrylic box 2 is inlaid with four total reflection mirrors, which, together with the total reflection mirror in the lid 1, reflect the excess light emitted by the bottom LED ultraviolet lamp beads 5, making full use of the light source of the bottom LED lamp;

[0028] There are 16 sets of quartz test tubes 3. The dimensions of quartz test tube 3 are 20cm high and 4cm in diameter. They are embedded on the surface of the heat-insulating light-concentrating sheet 4. The surface of quartz test tube 3 is surrounded by copper wires for heating and temperature control. The wires are connected to thermistors and external power supplies to control the heating power of the copper wires.

[0029] The heat-insulating light-concentrating sheet 4 is 30*30cm in size. It isolates the temperature from the upper and lower interfaces and concentrates the light emitted by the LED ultraviolet lamp beads 5 below so that it can fully pass through the quartz test tube 3.

[0030] There are 16 LED ultraviolet lamp beads 5, which are embedded in an acrylic plate of a certain thickness and operate in parallel.

[0031] There are 4 cooling fans 6, each cooling fan dissipates heat for 4 LED ultraviolet lamp beads to ensure the lamp beads operate normally;

[0032] Four support bases 7 keep the four cooling fans 6 a distance from the desktop to allow for better heat dissipation.

[0033] This invention enables the LED light source to be first concentrated and then fully passed through the sample liquid in a temperature-controlled quartz test tube, thereby achieving the purpose of better utilizing the LED ultraviolet lamp to degrade toxic substances in the test tube; the wavelength of the LED ultraviolet lamp beads is not limited, and other types of light sources can be used to achieve similar effects.
