Photometer for Measuring the Characteristics of the Light Source with Directed Light Radiation
The accuracy of the measurement of the main photometric characteristic of the emitter determines the error for determining the total light flux of the light sources, especially light emitting diodes, for which it should not exceed 5 per cent. Existing measurement methods with the use of integrated s...

| 520 | |a The accuracy of the measurement of the main photometric characteristic of the emitter determines the error for determining the total light flux of the light sources, especially light emitting diodes, for which it should not exceed 5 per cent. Existing measurement methods with the use of integrated spheres, goniophotometers and goniophotometers of the near field require a great deal of time and have a great deal of value. To eliminate these shortcomings, a method for measuring the characteristics of light sources with directed light distribution is proposed based on the use of a set of meters located in a plane perpendicular to the main direction of the source radiation propagation. On the basis of this method, a photometer for measuring the characteristics of the directional light sources is developed, which allows to quickly, in real time, determine the characteristics of the emitters. The method of determining the parameters of light distribution of directed sources of light for the construction of its photometric body is not required to use a rotary means. Taking into account the significant influence of temperature fluctuations on the characteristics of LED light sources, it is possible will upgrade the proposed method for determining the photometric body of the radiation source in real time and when the temperature changes due to the introduction of additional elements in the future. | ||

Photometer for Measuring the Characteristics of the Light Source with Directed Light Radiation |
| abstract |
The accuracy of the measurement of the main photometric characteristic of the emitter determines the error for determining the total light flux of the light sources, especially light emitting diodes, for which it should not exceed 5 per cent. Existing measurement methods with the use of integrated spheres, goniophotometers and goniophotometers of the near field require a great deal of time and have a great deal of value. To eliminate these shortcomings, a method for measuring the characteristics of light sources with directed light distribution is proposed based on the use of a set of meters located in a plane perpendicular to the main direction of the source radiation propagation. On the basis of this method, a photometer for measuring the characteristics of the directional light sources is developed, which allows to quickly, in real time, determine the characteristics of the emitters. The method of determining the parameters of light distribution of directed sources of light for the construction of its photometric body is not required to use a rotary means. Taking into account the significant influence of temperature fluctuations on the characteristics of LED light sources, it is possible will upgrade the proposed method for determining the photometric body of the radiation source in real time and when the temperature changes due to the introduction of additional elements in the future. |
