Description

Technical Field

[0001] The utility model relates to an exposure machine, in particular to a UV curing lamp. Background Art

[0002] In the process of planar UV curing, edge effect refers to some special phenomena that occur in the edge area of ​​the cured coating, such as uneven thickness and difference in curing speed. Generally, it is because the internal structure of various materials involved in the curing process (such as coatings, substrates, etc.) may be uneven, such as tiny particles, bubbles, crystallized areas, etc., which will cause ultraviolet rays to scatter when passing through. Scattering may cause uneven distribution of ultraviolet energy, resulting in uneven thickness and hardness of the cured coating. Therefore, the intensity (power) of the UV light source can be increased. A higher light source intensity can ensure that there is enough energy to promote the rapid curing of the resin and reduce incomplete curing or curing speed differences caused by insufficient energy. In this way, the degree of curing at the edge can be as close as possible to that of the center area, thereby improving problems such as uneven thickness and difference in curing speed. However, the existing commonly used UV curing lamps cannot meet the heat dissipation requirements of high-intensity UV light sources. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a high-power UV curing lamp with high heat dissipation efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A high-power UV curing lamp with high heat dissipation efficiency comprises a profile body, wherein a lamp trough is arranged on the bottom surface of the profile body, and a UV lamp board is installed in the lamp trough; at least three heat sinks are arranged on the top of the profile body along the length direction of the profile body, and the heat sinks are symmetrically arranged on the top of the profile body.

[0006] The UV lamp panel is provided with a plurality of arranged lamp beads.

[0007] The heat sink and the profile body are integrally formed.

[0008] Both sides of the profile body are folded to form folded portions in a direction away from the heat sink, and the lamp trough is naturally formed between the two folded portions.

[0009] A raised portion is arranged on the inner side of the folded portion, and the raised portion and the bottom surface of the profile body are combined to form a sliding groove, and the UV lamp board is slidably inserted into the sliding groove.

[0010] The beneficial effects of the utility model are as follows: a lamp trough is arranged on the bottom surface of the profile body, and a UV lamp board is installed in the lamp trough; at least 3 heat sinks are arranged on the top of the profile body along the length direction of the profile body, and the heat sink increases the heat dissipation area of ​​the UV curing lamp, which can quickly disperse the heat and effectively and quickly reduce the temperature of the UV curing lamp; the heat sink is symmetrically arranged on the top of the profile body, which can make the heat generated by each lamp bead on the UV lamp board be evenly conducted to the heat sink, thereby avoiding the temperature difference of the UV curing lamp itself, which leads to uneven curing of the resin.
