Embodiment 1

[0027] Such as figure 1 with figure 2 As shown, the sleeve 1 is a hollow cylinder. The light source 2 (such as lamp beads or light bulbs) is set at one end of the fixed seat 3 of the cylinder, so that the optical axis of the light source 2 coincides with the central axis of the fixed seat 3, and the sleeve 1 is tapped with an external thread screwed with the fixed seat 3 The matched internal thread makes the fixing seat 3 and the sleeve 1 coaxially screwed. Wherein, the bottom surface 31 of the fixing seat 3 is used to be in close contact with the light source 2 to facilitate the heat dissipation of the light source 2 .

[0028] Usually, the other end of the fixing seat 3 opposite to the light source is further provided with a through hole 40 through which the wire 4 passes, and the light source 2 and the driving power are electrically connected through the wire 4 . The surface of the fixing seat 5 is provided with a scale, which is convenient for determining the distance ...

Embodiment 2

[0034] As an embodiment of the present invention, the inner surface of the sleeve 1 and the fixing seat 3 can be a smooth surface, correspondingly, the outer surface of the fixing seat 3 is also a smooth surface, as long as the two can move relatively coaxially. In addition, a raised line 12 is provided on the inner wall of the sleeve 1, and a groove 32 matched with the raised line 12 is provided on the fixed seat 3, so that the sleeve 1 and the fixed seat 3 are more stable when moving relatively coaxially, reducing the error, such as Image 6 with Figure 7 shown.

[0035] Such as Figure 8 As shown, the embodiment of the present invention also provides a method for determining the optimal position of the light source, and its implementation process is as follows:

[0036] In step S101, the light source is placed on one end of the sleeve, and the lens is placed on the other end of the sleeve, so that the optical axes of the lens and the light source coincide with the centr...

Abstract

The invention is applicable to the field of photoelectric detection and provides a device and method for determining the optimal position of a light source, as well as an optical system. The device comprises a sleeve, a fixing seat used for fixing a light source at one end of the sleeve, a pressing ring used for arranging a lens at the other end of the sleeve and an optical detector used for detecting the energy of light sent from the light source after the transmission of the lens, and the optical axes of the light source and the lens are coincident with the central axis of the sleeve. When the energy of light sent from the light source after the transmission of the lens is detected, the probe of the optical detector is coaxial with the sleeve and the light source or / and the lens is / are moved coaxially till the energy detected by the optical detector is maximum, and thus the optimal distance between the light source and the lens is determined. The corresponding device disclosed by the invention is simple in structure and easy to operate; and the detection method has few steps and can be used for quickly and accurate determining the optimal position of the light source.

Description

technical field [0001] The invention belongs to the field of photoelectric detection, in particular to a device, method and optical system for determining the optimal position of a light source. Background technique [0002] In the prior art, the idea of ​​designing a condensing lens is as follows: select a light source, construct a lens model for the light source and perform light simulation; verify the condensing effect of the lens after actually proofing the lens. However, in terms of lens surface shape, lens refractive index and light source model, limited to the actual processing technology, there will be some errors between the actual sample and the simulated model, resulting in differences between the actual sample and the theoretical simulation. Therefore, the position of the light source corresponding to the best light-gathering effect of the actual lens sample is generally not the position of the light source corresponding to the simulation, but a place slightly de...
