Abstract
The invention includes reflecting mirror and mirror support. There are several connectors and connecting pieces for connecting main arm on meter of measuring distributed luminosity on the mirror support. At least one of connectors and connecting pieces is movable cardan joint. Connector is a cardan joint including fixed seat of joint axis and universal articulated bearing pole. Connecting piece is composed of base including two brackets, screw and universal articulated bearing pole. Comparing prior art, length of bearing pole can be fine-tuned to adjust flatness of reflecting mirror. Adjusting length of bearing pole can tune pitch angle of reflecting mirror, and adjusting nut on connecting screw rod can tune left and right direction of reflecting mirror so as to ensure measuring precision.
Description
Technical field
The present invention relates to the reflective mirror that the measurement space light distribution is used.
Background technology
The reflective mirror that the measurement space light distribution is used is mainly used in the measurement floodlight, the spatial light intensity distribution of indoor illumination light fitting and the multiple photometric parameter of light fixture.Comprise: spatial light intensity distributes, the space isocandela curve, the curve of light distribution on the arbitrary section (can be respectively showing) by rectangular coordinate and polar coordinates, plane equiluminous distribution curve, probability curve, brightness limit curve, Luminaire efficiency dazzle grade, maximum allow apart from the effective luminous angle of height ratio, on penetrate the logical ratio of light, the total light flux of light fixture, effective luminous flux, usage factor.Because the reflective mirror of existing distribution luminosity meter, the flatness of its minute surface can not be regulated, and the luffing angle of minute surface, left and right directions can not free adjustment, make to have bigger error in the process of measuring.
Summary of the invention
Purpose of the present invention aims to provide the reflective mirror that the luffing angle, left and right directions of a kind of flatness of reflective mirror and minute surface can freely regulated measurement space light distribution be used.
The reflective mirror that measurement space light distribution of the present invention is used comprises reflective mirror, mirror holder, be distributed with several and be used to connect reflective mirror and the connector of mirror holder and the web member that is used to be connected mirror holder and distribution luminosity meter main frame arm on mirror holder, wherein connector and web member have a kind of movable universal joint that is at least.
Above-mentioned connector adopts usually to have joint shaft holder, universal turning joint bearing bar and twists the universal joint that is connected on the setting nut on the bearing rod, wherein, the end face of joint shaft holder and the back side of reflective mirror are fixed, and the bearing rod of universal turning joint bearing is connected by setting nut with mirror holder.
Said web member comprises base with relative two supports, be supported on screw rod on the support, twist on screw rod and be connected to universal turning joint bearing bar and setting nut, on universal turning joint bearing bar, twist and be connected to nut, base and mirror holder are fastening, and universal turning joint bearing bar is connected with distribution luminosity meter main frame arm.
The present invention is the gimbal suspension connector owing to what adopt reflective mirror and being connected of mirror holder, can finely tune the flatness of reflective mirror by the effective length of regulating the universal turning joint bearing bar on the connector, and make minute surface in the process of regulating, can not produce stress, it has overcome the defective that the reflective mirror flatness of distribution luminosity meter in the past can't be regulated, and can guarantee the accuracy of measurement data.Adopted web member to be connected between the main frame arm of mirror holder and distribution photometer, by regulating the nut on the universal turning joint bearing bar, can regulate the luffing angle of reflective mirror, the setting nut on the adjusting screw(rod), can regulate the left and right directions of reflective mirror, guarantee measuring accuracy.

Embodiment
Reflective mirror of the present invention is connected with mirror holder, and being connected can all adopt with movable universal joint of the main frame arm of mirror holder and distribution luminosity meter links to each other, and also can be that one of them links to each other in movable universal joint mode.
With reference to Fig. 1, Fig. 2, the reflective mirror that the measurement space light distribution is used comprises reflective mirror 1, mirror holder 2, is distributed with several connectors 3 and is used for the connector 7 that links to each other with distribution luminosity meter main frame arm with three on mirror holder 2.In this example, said connector 3 as shown in Figure 3, it is to have joint shaft holder 5, universal turning joint bearing bar 4 and twist the universal joint that is connected on the setting nut 13 on the universal turning joint bearing bar, and joint shaft holder 5 links to each other by pin 6 with universal articulated shaft 4.The back side of the end face of joint shaft holder 5 and reflective mirror 1 can be glued, and universal turning joint bearing bar 4 utilizes nut 13 to be connected with mirror holder 2, can finely tune the flatness of reflective mirror by the effective length of regulating universal turning joint bearing bar.In order to strengthen the adjusting intensity of mirror holder, make mirror holder be reticulate texture usually.In order to prevent the careless impact failure in reflective mirror edge, can enclose metal coating ring 16 (being shown in Fig. 1) at the edge of reflective mirror 1, metal coating ring 16 is fixed on the mirror holder 2.
In this example, be used for connector 7 that mirror holder is linked to each other with the main frame arm 12 of distribution luminosity meter, see Fig. 4, shown in Figure 5, it comprises base 11 with relative two supports 9, be supported on the screw rod 8 on the support 9 and be connected universal turning joint bearing 10 on the screw rod 8, on screw rod 8, twist and be connected to setting nut 15, twist on universal turning joint bearing bar 10 and be connected to nut 14, base 11 is fastening with mirror holder 2, and universal turning joint bearing bar 10 utilizes nut 14 to be connected with main frame arm 12.Reflective mirror is installed in to be seen shown in Figure 6ly on the distribution luminosity meter main frame arm 12, like this, by regulating the nut 14 on the universal turning joint bearing bar, can regulate the luffing angle of minute surface, and the setting nut 15 on the adjusting screw(rod) can be regulated the left and right directions of minute surface.
