Description

Technical Field

[0001] This utility model belongs to the field of light bulb photometric parameter testing technology, specifically relating to an installation device for testing light bulbs inside an integrating sphere. Background Technology

[0002] An integrating sphere is a hollow sphere with its inner wall coated with a white diffuse reflective material. Also known as a photometric sphere or luminous flux sphere, it is primarily used to test the photometric parameters of light bulbs. When testing bulb parameters, the bulb needs to be fixed at the center of the sphere. However, due to the varying sizes of bulbs, the height of the bulb must be continuously adjusted to ensure it remains centered within the sphere.

[0003] Current technology involves fixing a thinner iron pipe to the top of the bulb, then securing a thicker iron pipe to the thinner pipe with screws. The height is adjusted by tightening the screws. An iron plate is welded to the bottom of the thicker pipe, and the lamp holder is fixed to this plate. The power cord runs through the iron pipe to the plate and connects to the lamp holder. This method has the following disadvantages: 1. Screw fixing is inconvenient and unstable, and prone to slippage. 2. Over time, the screws may strip or break. 3. Fixing the lamp holder directly to the iron plate will inevitably press down on the wire coming out of the iron pipe, causing the lamp holder to be unbalanced and the bulb to be off-center from the bulb. 4. Over time, the lamp holder pressing on the wire can easily damage the wire, causing leakage and creating a safety hazard. Utility Model Content

[0004] The purpose of this invention is to address the defects and shortcomings of existing technologies by designing a simple, reasonable, stable, reliable, and easily adjustable mounting device for testing the inner bulb of an integrating sphere.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an installation device for testing a bulb inside an integrating sphere, comprising a mounting base for fixing a bulb holder and an adjusting bracket for adjusting the height of the mounting base. The mounting base includes a first mounting plate and a second mounting plate spaced apart. The first mounting plate and the second mounting plate are respectively connected to the adjusting bracket and the bulb holder. The adjusting bracket includes a first adjusting rod and a second adjusting rod sleeved outside the first adjusting rod and capable of vertical extension and retraction along the first adjusting rod.

[0006] Preferably, the first mounting plate is fixedly connected to the lower end face of the second adjusting rod.

[0007] Preferably, the second mounting plate is disposed below the first mounting plate by means of studs.

[0008] Preferably, the second mounting plate has a wire hole corresponding to the lamp holder wiring position, and the wire hole is connected to the gap between the first mounting plate and the second mounting plate.

[0009] Preferably, the first adjusting rod is vertically disposed inside the integrating sphere, with its upper end fixed to the top of the integrating sphere, and the first adjusting rod has multiple limiting holes distributed along the height direction.

[0010] Preferably, the second adjusting rod is provided with a plurality of adjusting holes that cooperate with a plurality of limiting holes, and a limiting insert for positioning between the adjusting holes and the limiting holes.

[0011] Preferably, the height of the limiting hole and the adjusting hole are both 3mm, the distance between adjacent limiting holes and adjacent adjusting holes is 1cm, and the thickness of the limiting insert is 2mm.

[0012] After adopting the above technical solution, the mounting device for testing the lamp inside the integrating sphere provided by this utility model has the following beneficial effects:

[0013] (1) This utility model achieves bulb height adjustment by opening limiting holes and adjustment holes on the first and second adjusting rods and cooperating with limiting inserts. This avoids the risk of slippage and stripping of screws in the prior art, and has the advantages of convenient adjustment and stability.

[0014] (2) Through the structural design of the mounting base, this utility model can not only facilitate the fixing of the lamp holder, but also avoid squeezing the wire. This ensures that the bulb is located in the center of the sphere, ensuring the accuracy of the test, and also ensures that the wire is not squeezed, thus avoiding damage to the wire and eliminating safety hazards.

[0015] Therefore, this utility model has the advantages of simple structure, reasonable design, stability and reliability, easy adjustment, wide applicability and strong practicality. Attached Figure Description
