In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] As Figures 1-4 shown, a kind of ultraviolet aging test device for blue light chips in a preferred embodiment of the present utility model includes a housing 1, an ultraviolet lamp 2 and a yellow fluorescent rubber block 3. The bottom of the housing 1 is open. The ultraviolet lamp 2 is installed downward at the top inside the housing 1, that is, the ultraviolet light irradiates downward, and the light emitted by the ultraviolet lamp 2 basically does not shoot out of the housing 1. There are four yellow fluorescent rubber blocks 3, and the four yellow fluorescent rubber blocks 3 are respectively arranged on the outer side of the housing 1, that is, yellow fluorescent rubber is provided on the four sides of the housing 1. The tops of the yellow fluorescent rubber blocks 3 are respectively rotatably connected to the side parts of the housing 1. The bottom surface of the yellow fluorescent rubber block 3 is lower than the bottom surface of the housing 1. The four yellow fluorescent rubber blocks 3 are spliced to form a rectangular fluorescent rubber frame, and the fluorescent rubber frame encloses the bottom of the housing 1.

[0021] The working principle of this embodiment is as follows: During the test, the glowing blue light chip is placed on the platform, and then the housing 1 is covered on the blue light chip. The ultraviolet lamp 2 in the housing 1 works to irradiate the glowing blue light chip, thereby conducting an ultraviolet aging test on it. Since the bottom surface of the yellow fluorescent glue is lower than the bottom surface of the housing 1, at this time, the bottom surfaces of the four yellow fluorescent glue blocks are placed on the platform to support the housing 1, and the four yellow fluorescent glue blocks 3 are spliced to form a fluorescent glue frame surrounding the bottom of the housing 1. Therefore, the blue light emitted by the blue light chip can be converted into white light through the bottom of the yellow fluorescent glue and then irradiate outward, that is, the finally emitted light is white light, thus preventing personnel from being in the blue light irradiation environment for a long time and preventing the blue light chip from affecting the physical health of personnel during the ultraviolet aging test. When the test is not required, the yellow fluorescent glue is rotated so that the bottom surface of the yellow fluorescent glue is higher than the bottom surface of the housing 1. At this time, the yellow fluorescent glue no longer supports and holds the housing 1, avoiding the yellow fluorescent glue being pressed when not in use, which helps to ensure its service life.

[0022] Exemplarily, a yellow fluorescent glue plate 4 is provided in the housing 1. The yellow fluorescent glue plate 4 divides the interior of the housing 1 into a test chamber 11 and a heat dissipation chamber 12. The yellow fluorescent glue plate 4 is provided with ventilation holes 41 respectively communicating with the test chamber 11 and the heat dissipation chamber 12. A heat dissipation fan 5 is installed on one side of the housing 1. The air extraction end of the heat dissipation fan 5 is communicated with the heat dissipation chamber 12. The ultraviolet lamp 2 is arranged in the test chamber 11. The heat dissipation fan 5 can be set to work periodically and intermittently. When the heat dissipation fan 5 works, the air in the test chamber 11 enters the heat dissipation chamber 12 through the ventilation holes 41 and is finally pumped to the outside by the heat dissipation fan 5, which helps to dissipate the heat inside the housing 1. The blue light is converted into white light after passing through the yellow fluorescent glue plate 4, thereby preventing the blue light from being emitted to the outside through the heat dissipation fan 5.

[0023] Exemplarily, the ventilation holes 41 are gradually inclined from top to bottom from one end close to the test chamber 11 to the other end, making it difficult for the blue light emitted by the chip to pass through the ventilation holes 41, thereby preventing the blue light from being emitted to the outside through the ventilation holes 41 and the heat dissipation fan 5.

[0024] Exemplarily, a connecting block 13 is provided on the side of the housing 1. The side of the connecting block 13 is provided with a connecting groove 131 with an open bottom. The top of the yellow fluorescent glue block 3 is provided with a connecting portion 31. The top of the connecting portion 31 is arranged in the connecting groove 131. A connecting shaft 132 penetrates through both sides of the connecting portion 31 and the connecting groove 131 and is rotatably connected to the connecting portion 31. The connecting portion 31 can rotate around the axis of the connecting shaft 132 in the connecting groove 131, thereby realizing the rotational connection between the yellow fluorescent glue block 3 and the side of the housing 1.

[0025] Exemplarily, the bottom of the housing 1 is provided with support legs 15. The bottom surface of the support legs 15 is flush with the bottom surface of the yellow fluorescent glue block 3. During the test, the support legs 15 and the yellow fluorescent glue block 3 jointly support and hold the housing 1, thereby reducing the load on the yellow fluorescent glue block 3.

[0026] Exemplarily, a first wire passing hole 14 is provided at the top of the housing 1, and a sealing joint (not shown in the figure) is inserted into the first wire passing hole 14. The wire is connected to the ultraviolet lamp 2 through the sealing joint and the first wire passing hole 14 so that the ultraviolet lamp 2 is connected to an external power supply.

[0027] Exemplarily, a second wire passing hole 32 is provided on one side of the fluorescent glue frame so that the blue light chip under test is connected to an external power supply.

[0028] Exemplarily, a handle 16 is provided at the top of the housing 1 to facilitate the taking of the housing 1.

[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
