Problems solved by technology

[0008] However, in order to be suitable for lamps of various sizes and weights, the existing rotating lamp type light distribution curve meter is relatively bulky, and the large one weighs more than 300 kg, 16 meters high and 12 meters wide. The main body of the light distribution curve machine is accommodated in a large darkroom, and the cost of making the main body is relatively high, so the cost of testing is relatively high.

Embodiment Construction

[0049] The present invention will be described with preferred embodiments and accompanying drawings. Such descriptions explain the structure and steps of the present invention, and are only used for illustration rather than to limit the claims of the present invention. Therefore, the present invention can be widely practiced in other embodiments besides the preferred embodiment described in the description.

[0050] see Figure 6 , is a schematic diagram of the light distribution curve device of the present invention, which includes a first base 602 , a second base 604 , and a computer system device 606 . It can be seen from the figure that there is a certain distance between the first base 602 and the second base 604, and this distance can be adjusted according to the size and type of the lamp to be tested, that is, the light source to be tested. In a preferred embodiment of the present invention, the distance between the first base 602 and the second base 604 may be 50 cm t...

Abstract

The invention relates to a goniophotometer, including a first pedestal, a second pedestal and a computer system. The first pedestal includes an L-type light arm, a first holding arm, a second holding arm and a driving device. One end of the L-type light arrm is connected to a rotationg platform and arranged on a base; the first holding arm and the second holding arm are connected to the rotation platform and arranged at the other end of the L-type light arm; the driving device is coupled to the rotation platform. The second pedestal includes a laser positioning device, a spectrometer and a light source detection device. The spectrometer is arranged at back of the laser positioning device, the laser positioning device is arranged at the same axes with the spectrometer, the light source detection device is arranged over the spectrometer and the laser positioning device, and the computer system is coupled to the first rotation platform and the second rotation platform. In the goniophotometer provided in the utility model, the usage of the power line and the signal is reduced, the power consumed by the driver is reduced, and energy can be effectively saved.

Description

technical field [0001] The invention relates to a light distribution curve meter, in particular to a rotating lamp type light distribution curve meter with a simple structure. Background technique [0002] The light intensity distribution in each direction is an important parameter of light sources and lamps. The light distribution curve meter is used to accurately measure the light intensity distribution of light sources and lamps with angles. It can provide more accurate and reliable data for reference when designing lighting lamps. [0003] The light distribution curve meter mainly measures the light beams generated by a certain light source in various angles to understand the distribution of the light beams projected by the luminaire, regardless of the material or smoothness of the luminaire. The light distribution curve meter can measure the candle power value of a series of angles for the lamps and lanterns. According to these values, using the designed computer softw...
