Description

Technical Field

[0001] The utility model relates to the technical field of luminous flux testing, in particular to a testing fixture for the luminous flux of a lamp string. Background Art

[0002] Luminous flux test refers to the measurement of the radiant power that the human eye can feel through an integrating sphere. It is equal to the product of the radiant energy of a certain band per unit time and the relative visibility of the band. Since the relative visibility of the human eye to light of different wavelengths is different, when the radiant power of light of different wavelengths is equal, the luminous flux is not equal. In order to make the lamp more stable inside the integrating sphere, a corresponding fixture is generally used.

[0003] At present, the existing luminous flux testing device cannot fix the light string well when in use, because the integrating sphere is more suitable for measuring point light source products such as bulbs, and ordinary fixtures cannot convert the light string into a point light source, so the light parameter measurement of the light string will be inaccurate.

[0023] The top of the bulb-shaped mold 14 is fixedly connected to an Edison screw ring 13, the outer surface of the bulb-shaped mold 14 is fixedly connected to a fixing frame 15, a second semicircular shell 5 is arranged on the outer side of the second rectangular block 10, and the outer surface of the second semicircular shell 5 is fixedly connected to the left side of the second rectangular block 10. By providing the second semicircular shell 5, the internal space can be sealed by the second semicircular shell 5 and the first semicircular shell 1 to ensure that light does not leak out.

[0024] The inner wall of the fixing frame 15 is threadedly connected to two threaded shafts 16, and the ends of the two threaded shafts 16 that are away from each other are fixedly connected to a rotating plate 18. The inner wall of the first semicircular shell 1 is fixedly connected to two support frames 7, and the ends of the two support frames 7 close to the bulb-shaped mold 14 are commonly fixedly connected to a baffle 8. By providing the support frames 7, the baffle 8 can be fixed by the support frames 7, and the baffle 8 can prevent direct light from being transmitted to the sensing end of the detection device.

[0025] The ends of the two threaded shafts 16 that are close to each other are fixedly connected to the rotating shaft 19, and two clamping plates 20 are arranged inside the fixing frame 15. The inner wall of each clamping plate 20 is fixedly connected to the bearing 21, and the inner wall of the first semicircular shell 1 is fixedly connected to the sensing device 6, and the inner wall of the first semicircular shell 1 is fixedly connected to the fixed shaft 12, and the bottom end of the fixed shaft 12 is fixedly connected to the circular plate 9, and the inner wall of the circular plate 9 is threadedly connected to the outer surface of the Edison screw ring 13. By providing the fixed shaft 12 and the circular plate 9, the circular plate 9 can be fixed by the fixed shaft 12 so that the circular plate 9 can be in the middle part of the device.

[0026] The inner ring of each bearing 21 is fixedly connected to the outer surface of the rotating shaft 19, the outer surface of the second semicircular shell 5 is fixedly connected to a fixing seat 4, the bottom surface of the fixing seat 4 is fixedly connected to two universal wheels 3, and the outer surface of the first semicircular shell 1 is fixedly connected to a fixing block 2. By providing the fixing seat 4 and the universal wheel 3, the second semicircular shell 5 can be driven to unfold by the universal wheel 3, so that the light strip can be placed inside the device.

[0027] The working principle of the utility model is as follows: first, the induction device 6 is connected to the power supply. When the power supply is connected, the device can be used normally. When the device needs to be used, it is only necessary to wrap the light strip around the inside of the bulb-shaped mold 14. The card slot 17 provided on the outer surface of the bulb-shaped mold 14 enables the light strip to be carded inside the card slot 17, so that it can surround the bulb-shaped mold 14 for one week. With the Edison screw ring 13, the bulb-shaped mold 14 can be threadedly connected to the inside of the first semicircular shell 1 and the second semicircular shell 5. By applying a rotating force to the rotating plate 18, the threaded shaft 16 can be driven to rotate.
