DETAILED DESCRIPTION

[0029] The present application will be further described in detail below with reference to the drawings. EMBODIMENT

[0030] Please refer to Figures 1-6 A dual-band UV LED lamp, comprising a base plate 1, a dam 2, a lens 3 and a support plate 5, the dam 2 is fixed on the base plate 1, the lens 3 is arranged on the dam 2, the chip is inside the dam 2, and the ultraviolet light generated by the chip adopts 275 nanometer and 395 nanometer dual-band, so that the UV LED lamp has wide applicability and high flexibility, the base plate 1 is fixedly provided with a solder pad 4 at the bottom, the dam 2 is provided with a sink groove 6 at the top, the support plate 5 is fixedly arranged at the bottom of the lens 3, the support plate 5 is embedded with the sink groove 6, a plurality of embedded holes 7 are arranged on the outer side of the support plate 5, a plurality of jacks 8 matched with the embedded holes 7 are arranged on the outer side of the dam 2, and an insertion rod 9 is arranged in the jack 8.

[0031] Some embodiments of the present application will be described in detail below with reference to the drawings:

[0032] Please refer to Figures 1-6The lens 3 is fixed on the top of the dam 2 by setting the support plate 5 at the bottom of the lens 3, embedding the support plate 5 in the sink groove 6 at the top of the dam 2, and fixing the support plate 5 in the sink groove 6 by inserting the plug rod 9 in the insertion hole 8 and the embedding hole 7, so that the lens 3 is fixed on the top of the dam 2 without using adhesive.

[0033] The outer side of the plug rod 9 is provided with an outer thread 10, which cooperates with the inner thread provided in the insertion hole 8. Further, the outer thread 10 is arranged at the tail end of the plug rod 9. Since the outer thread 10 is arranged at the tail end of the plug rod 9, and the inner diameter of the embedding hole 7 is smaller than the inner diameter of the insertion hole 8, and the outer diameter of the head end of the plug rod 9 is equal to the inner diameter of the embedding hole 7, the head end of the plug rod 9 is not blocked by the thread provided in the insertion hole 8 during the insertion of the plug rod 9 into the insertion hole 8. The head end of the plug rod 9 is gradually embedded in the embedding hole 7 of the support plate 5, and the plug rod 9 is fixed by the cooperation of the outer thread 10 and the insertion hole 8.

[0034] In order to further improve the connection effect between the support plate 5 and the dam 2, the inner side of the sink groove 6 is provided with an insertion slot 11 cooperating with the insertion hole 8, and the inner diameter of the insertion slot 11 is equal to that of the embedding hole 7. After the plug rod 9 is embedded in the embedding hole 7, the head end of the plug rod 9 is gradually embedded in the insertion slot 11 as the plug rod 9 continues to penetrate. At this time, the support plate 5 is at the middle section of the plug rod 9 through the embedding hole 7, and the plug rod 9 penetrates the sink groove 6 where the support plate 5 is located, thereby improving the limiting effect of the support plate 5 in the sink groove 6.

[0035] It is worth noting that the support plate 5 is a ring-shaped surrounding plate, and the sink groove 6 is a ring-shaped groove cooperating with the support plate 5. The arrangement of the ring-shaped surrounding plate can improve the overall strength of the support plate 5, and the cooperation of the ring-shaped surrounding plate and the sink groove 6 can improve the sealing effect of the inside of the dam 2.

[0036] At the same time, the insertion hole 8 is symmetrically arranged on the outer side of the support plate 5, and the insertion hole 8 is symmetrically arranged on the outer side of the dam 2. The symmetrically arranged plug rod 9 can ensure that the support plate 5 is uniformly stressed in the sink groove 6.

[0037] In order to further improve the sealing performance of the inside of the dam 2, the sealing ring pad 12 is fixedly arranged at the top of the dam 2. When the lens 3 is placed on the upper surface of the dam 2, the upper and lower surfaces of the sealing ring pad 12 are in contact with the lens 3 and the dam 2, respectively. The sealing ring pad 12 is used to isolate the inside of the dam 2 from the external environment, preventing external moisture from entering the inside of the dam 2 and affecting the performance of the chip in the dam 2.

[0038] In addition, the embedding hole 7 is a conical hole diverging outward. When the plug rod 9 enters the embedding hole, the head end of the plug rod 9 first contacts the conical hole on the outer side of the embedding hole 7. As the plug rod 9 gradually penetrates, the support plate 5 with the lens 3 moves downward and presses the sealing ring pad 12, further improving the sealing performance of the sealing ring pad 12.

[0039] The installation method of the lens 3 will be described below:

[0040] First, the support plate 5 below the lens 3 is inserted into the sink 6 on the dam 2, at this time the embedded hole 7 of the support plate 5 matches the insertion hole 8 of the dam 2;

[0041] Then, the insertion rod 9 is inserted into the insertion hole 8, as the insertion rod 9 continues to go deep, the head end of the insertion rod 9 gradually embeds into the embedded hole 7 of the support plate 5, and the outer thread 10 outside the insertion rod 9 also matches the inner thread inside the insertion hole 8, rotate the insertion rod 9 until the head end of the insertion rod 9 is inserted into the insertion slot 11 inside the sink 6, thereby limiting and fixing the support plate 5 in the sink 6, and further fixing the lens 3 on the dam 2;

[0042] In the process of inserting the insertion rod 9 into the embedded hole 7, the insertion rod 9 goes deep into the embedded hole 7 through the tapered hole of the embedded hole 7, and the support plate 5 is pulled down, thereby driving the lens 3 to press down, so that the lens 3 extrudes the sealing ring pad 12, thereby isolating the internal environment of the dam 2 by the sealing ring pad 12. Preventing external water vapor from entering the inside of the dam 2 to affect the normal use of the chip.

[0043] In another embodiment of the present technical solution, as shown in Figure 4 and Figure 6 The insertion hole 8 is provided with a receiving groove 13 outside, the tail end of the insertion rod 9 is fixedly provided with a fixed cap 14, the outer side of the fixed cap 14 is provided with an internal hexagonal groove 15, when the insertion rod 9 is completely inserted into the insertion hole 8, the fixed cap 14 is in the receiving groove 13, which can prevent the fixed cap 14 from protruding outside the surface of the dam 2, and ensure the flatness of the outer side surface of the dam 2.

[0044] In the present technical solution, the part at the embedded hole 7 can be replaced by a metal sleeve to improve the strength of the embedded hole 7.

[0045] Those skilled in the art should understand that the embodiments of the utility model shown in the above description and the drawings are only as examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structure principle of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can have any deformation or modification without departing from the principle.
