Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0018] Such as figure 1 , figure 2 and image 3 As shown, the method for improving the detection accuracy of light intensity detection standard lamps, the steps include:
[0019] Step 1: Install a glass stem 3 between the lamp cap 1 and the lamp housing 2, and lead out two guide wires 5 from the glass stem 3. The diameter of the guide wire 5 is about 1.2mm, and the guide wire 5 is kept vertical as a whole. The top end is bent to form a horizontal section 6, and the front end of the horizontal section 6 is continuously bent to form a vertical section 7. By bending at the lower end of the guide wire 5, the distance between the horizontal sections 6 at the top of the guide wire 5 can be increased, and the la...

The invention relates to a method for improving the detection precision of a light intensity detection standard lamp. The method comprises the steps that firstly, a glass stem is arranged between a lamp holder and a lamp shell, two wires are led out of the glass stem and are kept vertical as a whole, horizontal sections are formed at the top ends of the wires in a bent mode, and the front ends of the horizontal sections are continued to be bent to form vertical sections; secondly, a lamp filament is arranged, the lamp filament is in a square wave shape from left to right, and the lamp filament is in the same plane; thirdly, the two ends of the lamp filament are connected with the vertical sections of the wires, the distance between the plane where the lamp filament is located and the front side of the lamp shell is equal to the distance between the plane where the lamp filament is located and the rear side of the lamp shell through adjustment, and the distance between the left end of the lamp filament and the left side of the lamp shell is equal to the distance between the right end of the lamp filament and the right side of the lamp shell through adjustment; fourthly, a fixing strip is welded to the vertical section of the lamp filament and used for fixing the position of the lamp filament. Due to the fact that the lamp filament and a support are arranged in different planes, the defect that lamplight is shielded by the support is well overcome, and the detection precision is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of lamp manufacturing, in particular to a method for improving the detection accuracy of standard lamps for light intensity detection. Background technique [0002] In optical radiometry, the original standards for reproducing various photometric and radiometric sheets, such as blackbody furnaces and absolute radiometers, are technically complex and expensive. Therefore, it is necessary to have corresponding standard lamps to copy the bit quantity value reproduced from the original standard as a secondary standard, and to pass the value held by it step by step. Luminous Intensity Standard Lamp A standard lamp used to reproduce and communicate the value of a unit of luminous intensity. Its luminous performance is stable, and the filaments are in the same plane. The lamp housing has a specific shape that is well adapted to the requirements of the inverse square law of distances. Currently commonly used stan...
