[0025] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present application. The present application is not limited to the description of the following embodiments.

[0026] like Figure 1 and 2 As shown, a water-cooled UV curing LED lamp with temperature protection includes a lamp holder body 1, a heat dissipation cover plate 2, a light-emitting module 3 and a top lampshade 4. The lamp holder body 1 includes a top surface, a bottom surface opposite to the top surface and a heat dissipation system; the heat dissipation system includes a water flow groove 5, the water flow groove 5 penetrates the bottom surface and extends from the bottom surface to the top surface, and the depth of the water flow groove 5 is less than the distance from the top surface to the bottom surface. The top lampshade 4 is fixedly arranged on the top of the lamp holder body 1. The light-emitting module 3 is located between the top lampshade 4 and the lamp holder body 1, the light-emitting module 3 is fixedly connected to the lamp holder body 1, and the bottom of the light-emitting module 3 is in contact with the top surface of the lamp holder body 1. The heat dissipation cover plate 2 is fixedly arranged on the bottom of the lamp holder body 1, the heat dissipation cover plate 2 closes the notch of the water flow groove 5, and a sealing ring 6 is fixedly arranged between the heat dissipation cover plate 2 and the lamp holder body 1. The heat dissipation cover plate 2 is provided with a water inlet 21, a water outlet 22 and a temperature probe 7 for detecting the water temperature in the water flow trough 5, and the water inlet 21 and the water outlet 22 are respectively connected to the water flow trough 5. When in use, the water inlet 21 and the water outlet 22 are respectively connected to the water circulation device, and the temperature probe 7 is connected to the control module of the water circulation device.

[0027] Refer to the attached Figure 3 As shown, further, the light-emitting module 3 is composed of a bottom plate and LED lamp beads, and the light-emitting module 3 is fastened and installed at the center of the lamp holder body 1 with screws, and is closely connected with the high-transparency quartz plate outside the light box; the top lampshade 4 is composed of a high-transparency quartz plate and a top, and is placed on the lamp holder body 1. The lamp holder body 1 is processed with a water flow groove 5, and the heat dissipation cover plate 2 uses a sealing ring 6 and is installed on the lamp holder body 1 with screws; the temperature probe 7 is installed on the heat dissipation cover plate 2 to monitor the water temperature and timely feedback the working status of the LED.

[0028] During operation, the light emitting module 3 generates heat, which is transferred to the lamp holder body 1 through the bottom plate of the light emitting module 3. The lamp holder body 1 transfers the heat to the cooling water in contact with it. During this process, the temperature probe 7 detects the cooling water temperature in real time and feeds it back to the control module to keep the cooling water flow at a more appropriate flow rate to avoid excessive temperature, which helps to maintain cooling efficiency. Through timely cooling, the luminous efficiency of the UVA LED is improved and the service life of the LED is extended.

[0029] Furthermore, in some embodiments, the lamp holder body 1 is an aluminum lamp holder body. The light-emitting module includes a base plate and LED lamp beads, the light-emitting module 3 is fixedly connected to the lamp holder body 1 by screws, and the heat dissipation cover plate 2 is fixedly connected to the lamp holder body 1 by screws. The principle of water-cooling heat dissipation is to select aluminum with better heat dissipation, directly open a water flow groove in the aluminum body to form an aluminum lamp holder body 1, introduce cold water through the water inlet 21, fully absorb heat, and then take away the heat by the flow of water. At the same time, a temperature probe is added to detect the water temperature, and the equipment is adjusted to the most suitable working conditions through the feedback of the water temperature. The advantages of water-cooling heat dissipation are high heat dissipation efficiency, high specific heat capacity of water, which can fully absorb heat, and quieter and cleaner operation, thereby increasing the luminous efficiency of LED equipment and extending its life.

[0030] See attached Figure 4 As shown, in some embodiments, the water flow trough 5 includes a plurality of branch water troughs 51, and the plurality of branch water troughs 51 are arranged side by side, and the plurality of branch water troughs 51 are connected end to end in sequence, and the water inlet 21 is connected to the head of the water flow trough 5 located at the first position among the plurality of water flow troughs 5, and the water outlet 22 is connected to the tail of the water flow trough 5 located at the last position among the plurality of water flow troughs 5.

[0031] During operation, the cooling water flows through each water distribution groove 51 in sequence, which increases the contact area between the cooling water and the lamp holder body 1 and helps to improve the heat dissipation efficiency.

[0032] See attached Figure 1 and 2 In some embodiments, the light emitting module 3 includes a plurality of LED boards, and the circuits between the LED boards are connected in parallel. A separate power supply can ensure that when a part has a problem, the normal operation of other modules is not affected. The external dimensions of the device can be spliced ​​in multiple ways according to product requirements, and the installation is convenient and quick.

For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
