Detailed description of the invention
Fig. 1 is one schematic diagram of embodiment of this photoelectric power switch.
Fig. 2 is two schematic diagram of embodiment of this photoelectric power switch.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
Embodiment one:
In embodiment one shown in Fig. 1, photoelectric power switch includes inner circular core 1, on the inner circular core 1 around the home
There is the endless solenoid 2 being made of resistive conductor, resistive conductor surface is equipped with insulating layer, so that each circle resistive conductor laterally insulate;It is described
It is equipped with annular white light 3 outside endless solenoid 2, fixes one week Transparent color band 31 outside the annular white light 3, it is described transparent
Colour band 31 is arranged in order by the wide Transparent color lattice of different colours, e.g., thoroughly by red, orange, yellow, green, blue, indigo, purple 7
Light colour grillages arranges;Being sticked outside the Transparent color band 31 has an adjusting change 4, and the main body for adjusting change 4 is by light
Diffusion material is learned, acrylic material is such as atomized and constitutes, and the one layer of photomask 41 that be sticked on the internal ring wall of adjusting change 4, the shading
A loophole 410 is only opened up on film 41, the light after the Transparent color band 31 of the annular white light 3 is only capable of passing through
The loophole 410 enters in the main body for adjusting change 4, and spreads in the main body for adjusting change 4, turns entirely adjusting
The main body of ring 4 issues monochromatic light;A moving contact 42 is fixedly connected on the inside of the adjusting change 4, the moving contact 42 is being adjusted
In 4 rotary course of change, the contour around the endless solenoid 2 is rotated, and the moving contact 42 is during rotation, successively with ring
Each circle conducting wire in shape solenoid 2 is in electrical contact, and contact form is consistent with solenoid type slide rheostat;The annular helical
One line end 21 of pipe 2 is electrically connected the first terminals (not shown) of photoelectric power switch, another line end is vacant;Moving contact
42 are electrically connected to a conducting ring 421, and the conducting ring 421, which is nested with, is being set to leading for the center point of the endless solenoid 2
Electric axis 422, the conductive shaft 422 are electrically connected the second terminals (not shown) of the photoelectric power switch;The annular is white
Two input terminals of light lamp 3 are electrically connected the first, second terminals of photoelectric power switch.
Above-mentioned photoelectric power switch in use, rotates the adjusting change 4, that is, the moving contact 42 is adjusted
On-position on the endless solenoid 2 adjusts the resistance value of the endless solenoid 2 access circuit, to adjust electricity
The power on road;When moving contact 42 is in different on-positions, the loophole 410 adjusted in change 4 is in face of described transparent
The Transparent color lattice of different colours on colour band 31, to make to enter the intracorporal lighting color of master for adjusting change 4 with the ring
The variation of the access resistance value of shape solenoid 2 and change;To the color presented according to change 4 is adjusted, that is, can determine whether current
Power gear e.g. can arrange a kind of color and represent a gear;Photoelectric power switch electrical structure is simple, is hardly damaged.
Embodiment two:
For embodiment two shown in Fig. 2, with embodiment one the difference is that: the inner circular core 1 is by silicon steel
Piece is formed by stacking, and silicon steel sheet is parallel to drawing, to inhibit eddy current;It is described adjust change 4 main body radially from the inside to surface by
Reflecting layer is radially equidistant to be separated into multilayer independently luminous circular layer, and in the main body of adjusting change 4, from the light transmission of the photomask 41
It is radially outward provided with a closed transparent radial slide 5 at hole 410, is equipped with an iron shot 51, institute in the radial slide 5
It states iron shot 51 and connects a pressure spring 52, the inner end of the pressure spring 52 is connected to the inner end of the radial slide 5;In nature
Under, the pressure spring 52 flexes outward, and the iron shot 51 is moved to the outer end of radial slide 5, i.e., state as shown in Figure 2;With institute
The electric current stated in endless solenoid 2 increases, and the inner circular core 1 increases the magnetic attraction of the iron shot 51, makes the pressure spring 52
It is gradually compressed, the iron shot 51 is gradually moved to the inner end of the radial slide 5;Enter the diameter from the loophole 410
Illumination into slideway 5 is hampered by the iron shot 51, can only enter several layers of luminous circular layers of 51 inside of iron shot;To root
According to the luminous Ring Width of the entire main body for adjusting change 4, it can substantially judge that the photoelectric power switchs corresponding electricity consumption
The current power of system.In this way, current shift may determine that according to the luminescent color for the main body for adjusting change 4, and according to its hair
Light Ring Width, and may determine that the current power situation of circuit;The instruction function of switching the photoelectric power obtains biggish
It expands.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, made any modification, equivalent replacement be should all be included in the protection scope of the present invention.
