Description

Handheld luminance meter

Technical Field

The utility model relates to a luminance detects technical field, concretely relates to hand-held type luminance meter.

Background

The luminance meter is a metering instrument for measuring light and color. The brightness meter is one of the necessary common instruments and equipment for each chemical analysis laboratory, and is widely applied to various quantitative and qualitative analyses. The luminance meter mainly adopts a pair of light holes with a certain distance to receive the luminous flux of a fixed solid angle and a fixed light projection area, and the value of the luminous flux does not change with the distance of an object as long as the surface area of the object is large enough. To aim the object under test, imaging systems are often employed. The light source to be measured is imaged on the reflector with the hole (front light hole) after passing through the objective lens, wherein one part of the light source is received by human eyes through the reflector and the ocular lens so as to aim and monitor the clear imaging surface to be coincided with the reflector with the hole; the other part of the light passes through the small hole on the reflector and reaches the V (lambda) receiver through the rear light hole. The brightness value is displayed by a pointer or a digital header;

present luminance counts for hand-held type and fixed, the hand-held type luminance meter can directly be held with the hand and remove the use, owing to do not possess the fixing base, can't fix it and use on the fixture, and fixed fix on test platform or A-frame for the luminance meter, owing to do not possess the grab handle, lead to the inconvenient direct hand removal of using of fixed luminance meter, hand-held type luminance meter and fixed luminance meter can not be general, need prepare two luminance meters under certain test environment, the practicality is lower, it is comparatively inconvenient to use, therefore, need improve current luminance meter.
