To this end, the utility model discloses a kind of luminance detection equipment, including lighting mirror, light-guiding pillar, housing, sensor and
Circuit board, described case top is provided with the through hole installing light-guiding pillar, and described lighting mirror is fixing with light-guiding pillar to be connected, described circuit board
Being fixed on outer casing bottom, described sensor is fixing, and its position is corresponding with light-guiding pillar on circuit boards, enters through light-guiding pillar for detection
The light entered, the bottom surface of described light-guiding pillar is inclined-plane.
Further, described inner walls is black light-absorbing face.
Further, described lighting mirror and light-guiding pillar are formed in one part, and described lighting mirror is hemispherical, and hemisphere face is for adopting
Bright finish.
Further, described housing is provided with mounting disc.
Further, the end face of whole light microscopic, the bottom surface of light-guiding pillar and whole light microscopic it is provided with between described light-guiding pillar and sensor
It is parallel to each other, and constitutes an air gap.
Advantageous Effects of the present utility model:
This utility model, by adjusting the gradient of light-guiding pillar bottom bevel, can accurately control the attenuation rate of sunlight, real
Now measure the intensity of all sunlights, and attenuation rate concordance is good, this utility model simple in construction, easily manufactured, low cost.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of this utility model embodiment one；
Fig. 2 is the generalized section of this utility model embodiment two.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
Embodiment one: as it is shown in figure 1, a kind of luminance detection equipment, including lighting mirror 1, light-guiding pillar 11, housing this enforcement of 3(
In example, housing 3 inwall is preferably black light-absorbing face, absorbs reflection light with more preferable), sensor 4 and circuit board 5, described lighting mirror 1
For dome-type, hemisphere face is lighting surface, so can accept sunlight to greatest extent, and lighting mirror 1 is fixing with light-guiding pillar 11 to be connected
(in the present embodiment, lighting mirror 1 and light-guiding pillar 11 are formed in one part, the most easily manufactured, with low cost), manufactures material general
Require good weatherability, as used Merlon and acrylic, because equipment mainly detects solar illuminance, directly shone by sunlight
Time is long, and temperature is higher.The top of housing 3 is provided with the through hole 31 installing light-guiding pillar 11, and lighting mirror 1 is tightly fastened (as used light
Learn glue bond) on through hole 31 (in other embodiments, lighting mirror can be tightly fastened with through hole, but between them
Gap must carry out shading treatment, prevents light from entering light-guiding pillar from which, affects certainty of measurement), circuit board 5 is directly locked in housing 3
Bottom (in other embodiments, it is also possible to be that the modes such as welding or bonding are fixed on housing bottom), to facilitate subsequent maintenance, and
Passing through shading treatment, it is ensured that the light that sensor 4 gathers, can only input from light-guiding pillar 11, sensor 4 is welded on (its on circuit board 5
Its embodiment can also be bonding alternate manner such as grade is fixed), its position is corresponding with light-guiding pillar 11, for detection through light-guiding pillar 11
The light entered, the bottom surface of light-guiding pillar 11 is inclined-plane, and sunlight, through out-of-date, can reflect away a part, black by housing of reflection light
Color extinction face absorbs, and a remaining part is directly refracted to sensor 4, so, by adjusting the oblique of light-guiding pillar 11 bottom bevel
Degree, can accurately control the attenuation rate of sunlight, and attenuation rate concordance is good.
Additionally, in this preferred embodiment, the outside part that is further fixed in mounting disc 32(the present embodiment being formed in one of housing 3,
Convenient manufacture, cheap), mounting disc 32 is provided with screw hole, and detection equipment is directly locked in and detection equipment by screw hole
The correspondence position at supporting equipment top.
The present embodiment luminance detection principle: after sunlight is gathered by lighting mirror 1, by light-guiding pillar 11 orientation sensor 4, too
Sunlight is when the bottom bevel of over-light-transferring pole 11, and a part of light is gone out by slant reflection, and these reflection light are inhaled by the black of through hole
Bright finish absorbs, and a remaining part is directly refracted to sensor 4, and sensor 4 will carry out intensity detection to this part light, detect
Transducing signal by the lead-in wire of circuit board 5 be transferred to correspondence equipment on carry out process display.By adjusting light-guiding pillar 11 end
The gradient on inclined-plane, portion, can accurately control the attenuation rate of sunlight, it is achieved the detection to all sunlight intensity.
Embodiment two:
As in figure 2 it is shown, the present embodiment is in addition to all modular constructions comprising embodiment one, at light-guiding pillar 11 and sensor
Being additionally provided with whole light microscopic 2 between 4, the bottom surface of light-guiding pillar 11 is parallel to each other with the end face of whole light microscopic 2, and constitutes an air gap.
Luminance detection principle: after sunlight is gathered by lighting mirror 1, is guided whole light microscopic 2 by light-guiding pillar 11, and sunlight passes through
Air gap will be through two secondary reflections, and these reflection light are absorbed by the black light-absorbing face of housing, and a remaining part passes through whole light microscopic 2 folding
Penetrating and be conducted to sensor 4, sensor 4 will carry out intensity detection to this part light, and the transducing signal detected is by circuit board 5
Lead-in wire is transferred on the equipment of correspondence carry out processing display.By adjusting the angle of air gap, can accurately control declining of sunlight
Lapse rate, it is achieved the detection to all sunlight intensity.
Although specifically show and describe this utility model in conjunction with preferred embodiment, but those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
