[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiment 1

[0025] See attached Figure 1-8 The utility model provides a light source base with a bulb, including a base and a bulb 30. The base includes an outer cylinder 12, and an inner cylinder 11 is fixedly installed inside the outer cylinder 12; wherein a shading plate 13 is installed on the top wall of 12, and a light-transmitting hole 14 is opened on the shading plate 13.

[0026] A lamp holder 31 is installed in the middle position of the top wall of the inner cylinder 11, and the bulb 30 is installed on the lamp holder 31. An installation chamber is provided between the inner cylinder 11 and the outer cylinder 12. A protective cover 20 (the protective cover 20 is a cylindrical sleeve with openings at both ends) is movably installed inside the installation chamber. A through groove is provided on the top wall of the outer cylinder 12. The protective cover 20 movably penetrates through the inside of the through groove and is fixed in position by a limiting assembly; wherein, the inner diameter of the protective cover 20 is larger than the outer diameter of the bulb 30, that is, the protective cover 20 will not contact the outer wall of the bulb 30 when moving up and down.

[0027] The limiting assembly includes a limiting groove 25 which is annularly opened along the inner wall of the outer tube 12. The inner wall of the outer tube 12 is also provided with two longitudinally opened slide grooves 24. The top of the slide groove 24 is connected to the inside of the limiting groove 25. Two sliders 23 are fixedly installed on the outer wall of the protective cover 20. The two sliders 23 are respectively slidably connected to the inside of the slide groove 24; wherein, when the slider 23 enters the inside of the limiting groove 25 from the top of the slide groove 24, the slider 23 can be made to enter the limiting groove 25 by rotating the protective cover 20 (the slider 23 cannot move in the longitudinal position after entering the inside of the limiting groove 25). At this time, the protective cover 20 can cover the outside of the bulb 30.

[0028] A top plate 21 is rotatably connected to the top wall of the protective cover 20 via a rotating shaft 22, a fixing plate 26 is fixedly installed on the side wall of the protective cover 20, and a blocking rod 27 is fixedly installed on the outer wall of the fixing plate 26; in order to fully protect the bulb 30, the top opening of the protective cover 20 can be closed by the top plate 21, and there is friction between the inner wall of the mounting hole on the top plate 21 and the outer wall of the rotating shaft 22, that is, the top plate 21 will not rotate easily without applying external force to rotate the top plate 21. In addition, the blocking rod 27 can facilitate the rotation of the protective cover 20, that is, when the protective cover 20 is moved out from the inside of the installation chamber, the protective cover 20 can be rotated by rotating the top plate 21 under the obstruction of the blocking rod 27, so that the staff can rotate the protective cover 20 conveniently.

[0029] A bottom plate 40 is detachably mounted on the bottom wall of the outer cylinder 12, a plurality of threaded holes 42 are provided on the bottom wall of the outer cylinder 12, a plurality of through holes 41 are provided on the outer wall of the bottom plate 40, a screw 43 is movably mounted inside the through hole 41, the end of the screw 43 is threadedly connected to the inner wall of the threaded hole 42, a support rod 15 is fixedly mounted on the outer wall of the bottom plate 40, and the support rod 15 is mounted on the illuminance meter photometric device; wherein, the base can be disassembled from the bottom plate 40, thereby facilitating the subsequent disassembly and maintenance of the negative pressure fan 53.

[0030] A heat dissipation hole 51 connected to the interior of the inner tube 11 is provided on the outer wall of the bottom plate 40, and a mounting frame 52 is fixedly installed on the outer wall of the bottom plate 40, and a negative pressure fan 53 is installed on the mounting frame 52; wherein, a power supply 32 is installed inside 11, and the power supply 32 is used to supply power to the light bulb 30 and the negative pressure fan 53, and an air inlet connected to the interior of the inner tube 11 is provided on the top wall of the inner tube 11. The negative pressure fan 53 can accelerate the heat dissipation effect of the electronic components inside the inner tube 11. When the light bulb 30 is lit, the negative pressure fan 53 is turned on, and the blades of the negative pressure fan 53 rotate, so that the hot air inside the inner tube 11 is discharged to the outside of the inner tube 11 through the heat dissipation hole 51, thereby accelerating the heat dissipation inside the inner tube 11.

[0031] In this embodiment, the working principle of the device is as follows: when the bulb 30 is covered, the top plate 21 can be pulled, and the top plate 21 drives the protective cover 20 to move out from the inside of the installation chamber. When the slider 23 moves to the inside of the limiting groove 25, the top plate 21 drives the protective cover 20 to rotate, so that the slider 23 enters the limiting groove 25, so that the protective cover 20 can maintain a stable longitudinal position, and then the top plate 21 is rotated clockwise so that the top plate 21 covers the top opening of the protective cover 20, so that the bulb 30 can be protected by the protective cover 20;

[0032] The device directly pulls the protective cover 20 out from between the inner tube 11 and the outer tube 12 to cover the outside of the bulb. There is no need to cover the protective cover 20 from above the bulb, which avoids the protective cover 20 and the bulb 30 from colliding with each other, thereby improving the protection of the bulb 30.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
