[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0021] See also Figure 1-2 The present embodiment relates to a UV-LED curing lamp for printing, including a lampshade 100 and a curing lamp body composed of a lamp group 1 arranged therein, a focusing plate 2 for concentrating the light source is arranged on the outside of the lampshade 100, the focusing plate 2 is placed at the position of the lamp group 1 in the lampshade 100 and is arranged on the lampshade 100 around the periphery of the lamp group 1, and the side wall surface 21 of the focusing plate 2 accumulates inwardly along the periphery of the lamp group 1 and forms a certain angle.

[0022] Specifically in the present embodiment, this type of UV curing lamp for printing can be installed above or on the printing head in the printing equipment according to specific usage requirements. During the printing process, the UV light source emitted by this type of curing lamp can be accumulated under the action of the focusing plate 2 surrounding the outer periphery of the lamp group 1 below the lamp group 1 on the lampshade 100. The UV light source irradiates and accumulates downward along the side wall surface 21 formed by the focusing plate 2 at a certain angle, thereby concentrating the light source within a certain range. Through the design of the focusing plate 2, this type of UV curing lamp for printing can irradiate the UV light source more concentratedly on the printing material within a certain printing range, so that the UV light can fully penetrate and quickly cure the ink or coating, ensuring the uniformity of light received in the printing area and having a better curing effect. It can also avoid unnecessary influence on printing materials and printing effects due to local excessive or insufficient curing as much as possible, improve the quality of printed products while further improving the curing speed and efficiency, and because the concentration of the light source is enhanced, unnecessary UV light scattering can be reduced, further improving the utilization rate of the UV light source and reducing unnecessary light source waste and energy loss, and through effective light source concentration and irradiation, the workload of the lamp group 1 can also be reduced, saving certain production and use costs. In addition, during use, this type of curing lamp can be used according to the specific use environment and use requirements. The side wall surface 21 of the focusing plate 2 on the lampshade 100 can be selected at different inclination angles, so as to irradiate the UV light source within the adaptation range, and has high adaptability and practicality.

[0025] A heat dissipation component 3 for dissipating heat from the lamp group 1 is arranged above the lamp group 1 in the lampshade 100. The heat dissipation component 3 can play a certain heat dissipation role for the heat generated by the lamp group 1 during use, effectively dissipate the heat generated by the lamp group 1, and reduce the temperature of the lamp group 1, thereby avoiding unnecessary influence on the curing effect due to the excessive temperature of the lamp group 1 and extending the service life of the lamp group 1. In addition, the integrated structural setting of the heat dissipation component 3 in the lampshade 100 can facilitate the installation and use of this curing lamp, is suitable for different use environments, and further improves the applicability of this curing lamp.

[0026] See also Figure 4 The heat dissipation component 3 includes a fan 31 and a heat sink 32. The heat sink 32 is placed above the lamp group 1 and covers the lamp group 1 and is laid in the lampshade 100. A number of ventilation slots 102 are provided at corresponding positions of the lampshade 100 on both sides of the heat sink 32. The fan 31 is placed above the heat sink 32 and installed on the top of the lampshade 100 to be adapted and arranged in multiple groups. Specifically, during use, the fan 31 works to dissipate the heat generated by the lamp group 1 during long-term use through the heat sink 32 below, and continuously circulates and circulates air through a number of ventilation slots 102 provided at corresponding positions of the lampshade 100 on both sides of the heat sink 32 to ensure stable heat dissipation. The overall structure of this heat dissipation component 3 is simple, and with the arrangement of multiple groups of fans 31, it has good heat dissipation effect and is also convenient for inspection and maintenance.

[0027] The lampshade 100 is provided in a split structure, and the lamp assembly 1 and the heat dissipation assembly 3 are both installed in the lampshade 100 through a detachable structure.
