Description

Technical Field

[0001] This utility model relates to the field of light source packaging technology, and in particular to a broadband light source packaging structure. Background Technology

[0002] A broadband light source is a light source with a wide spectral range and weak temporal coherence, which can provide continuous spectral output and can be transformed into a single-wavelength or multi-wavelength tunable light source through filtering or tuning techniques.

[0003] There is an LED light source packaging structure (authorization announcement number: CN206685414U), which can effectively encapsulate the LED chip board by setting a heat dissipation circuit board, a phosphor layer and a silicone layer inside the package. The port of the package is sealed with a sealing plate, which ensures the effective transmission of LED light source.

[0004] However, traditional planar sealed transparent plates can only play a role in parallel refraction. When light is incident perpendicularly, they cannot change the direction of light propagation. This makes it difficult to adjust the direction of light propagation according to the actual application scenario, and thus has certain limitations in use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a broadband light source packaging structure to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A broadband light source packaging structure includes:

[0008] The encapsulation housing has an encapsulation cavity inside, which is a chamber for providing broadband light source, and the encapsulation housing has an insertion port on it;

[0009] A light source assembly is disposed within a packaging cavity and is capable of generating a broadband light source for light propagation.

[0010] A light-transmitting component is disposed on the encapsulation shell, and the light-transmitting component can reflect a broadband light source in parallel.

[0011] A refractive component is disposed at the socket and is used to adjust the propagation direction of a broadband light source.

[0012] Preferably, the outer wall of the encapsulation shell is provided with a threaded groove.

[0013] Preferably, the light source assembly includes:

[0014] A heat dissipation circuit board, wherein the heat dissipation circuit board is disposed within the encapsulation cavity;

[0015] The device includes two wires, one positive and one negative, which are electrically connected to the heat dissipation circuit board.

[0016] A chip board is disposed on the top side of a heat dissipation circuit board and is electrically connected to the heat dissipation circuit board.

[0017] A phosphor layer is disposed on top of the heat dissipation circuit board;

[0018] A reflective coating is sprayed onto the inner wall of the encapsulation cavity.

[0019] Preferably, the light-transmitting component includes:

[0020] A first transparent plate is disposed at the port of the encapsulation shell;

[0021] The second transparent plate is disposed inside the encapsulation cavity of the encapsulation shell.

[0022] Preferably, the refractive component includes:

[0023] A insertion frame, which is inserted into a socket;

[0024] A concave lens, which is embedded in a frame and located between a first transparent plate and a second transparent plate;

[0025] A convex lens is embedded in a frame and is located between a first transparent plate and a second transparent plate.

[0026] Preferably, a threaded collar is threaded into the threaded groove on the outer side wall of the packaging shell, and the top opening of the threaded collar is fitted onto the insert frame.

[0027] This application provides an insertion port at the end of the encapsulation shell. When a concave lens is embedded in the insertion frame and inserted into the insertion port, the broadband light source inside the encapsulation shell can achieve a diverging effect when propagating outward, thus increasing the illumination range of the broadband light source. When a convex lens is embedded in the insertion frame and inserted into the insertion port, the light source can achieve a converging effect. Therefore, by embedding a concave or convex lens in the insertion frame, different propagation directions of the broadband light source can be adjusted, expanding the application scenarios of the broadband light source and improving its adaptability.

[0036] like Figure 2 As shown, a packaging cavity 101 is provided inside the packaging shell 100, and the light source assembly 200 is disposed inside the packaging cavity 101.

[0037] like Figure 2As shown, the light source assembly 200 includes a heat dissipation circuit board 201, wires 202, a chip board 203, a phosphor layer 204, and a reflective coating 205. The inner wall of the encapsulation cavity 101 is provided with a heat dissipation circuit board 201. Two wires 202 are fixedly connected to the bottom of the heat dissipation circuit board 201. The two wires 202 are positive and negative terminals, respectively. The bottom ends of the two wires 202 extend out of the encapsulation shell 100. The top of the heat dissipation circuit board 201 is fixedly connected with a chip board 203. The chip board 203 and the heat dissipation circuit board 201 are electrically connected. The top of the heat dissipation circuit board 201 is fixedly connected with a phosphor layer 204. The phosphor layer 204 can seal and protect the chip board 203, and also facilitate the transmission of broadband light source. The inner wall of the encapsulation cavity 101 is coated with a reflective coating 205. The reflective coating 205 is made of epoxy resin, which has the advantages of high temperature resistance and good reflectivity, and can effectively reflect and transmit broadband light source.

[0038] like Figure 4 As shown, the light-transmitting component 300 includes: a first transparent plate 301 and a second transparent plate 302; the first transparent plate 301 and the second transparent plate 302 are respectively provided at the top port of the encapsulation shell 100. The first transparent plate 301 can keep the encapsulation cavity 101 sealed and encapsulated, and the first transparent plate 301 and the second transparent plate 302 facilitate the parallel refraction of light from the broadband light source.

[0039] like Figure 5 As shown, the encapsulation housing 100 has an insertion port 102.

[0040] like Figure 5 As shown, the refractive assembly 400 includes a frame 401, a concave lens 402, and a convex lens 403. The frame 401 is inserted into the socket 102. When the concave lens 402 is embedded in the frame 401, according to the refraction principle of the concave lens 402, the light from the broadband light source can be diffused, thus increasing the illumination range of the broadband light source. When the convex lens 403 is embedded in the frame 401, according to the refraction principle of the convex lens 403, the light from the broadband light source can be converged. Furthermore, by embedding the concave lens 402 or the convex lens 403 in the frame 401, the different propagation directions of the broadband light source can be adjusted, thereby increasing the application range of the broadband light source and improving its adaptability.

[0041] like Figure 5 As shown, the outer side wall of the encapsulation shell 100 is provided with a threaded groove 103, and a threaded collar 500 is installed in the threaded groove 103. The top part of the threaded collar 500 is sleeved on the encapsulation shell 100 and the insertion frame 401, which can block and limit the insertion frame 401 to prevent the insertion frame 401 from sliding out from the insertion port 102.
