Micro LED light angle meter (light distribution curve)

■ Application Functions

• Used to measure parameters such as light distribution curves, illuminance, light intensity data, beam angle, and luminous flux of small LED lamps (halogen lamps, cup lamps, spotlights, bulb lamps, mining lamps, etc.) and individual high-power LEDs.
• The instrument is designed with an optical dark box and light barriers or partitions, eliminating the need for a darkroom.
• The testing process is computer-controlled, simple to operate, easy to use, and cost-effective.
• Based on the type of lamp being tested, a corresponding print report is generated, which can be directly saved as a PDF file for easy communication and archiving.
• Test results can be exported in various formats, including IESNA (95, 2002) file format (*.ies), CIE file format (*.cie), and European Eulumdat (*.ldt) file format.
• It meets the requirements of the CIE-127 international standard and can be directly used as input data for internationally recognized lighting design software.

Photometric curve measuring instrument

■ Basic characteristics and principles

The unit of luminous intensity is the candela (cd). If the total luminous flux emitted by a light source in all directions of space is Φ, then the average luminous intensity of the light source is I0 = Φ/4π. The luminous intensity of a real light source is not uniformly distributed in all directions. The distribution curve should be plotted in polar coordinates according to the actual distribution of luminous intensity, which is called the spatial light intensity distribution curve or light distribution curve.

■ Product Advantages

• High cost-performance ratio: The instrument hardware is simple and can achieve a high level of measurement. It is equipped with a spectrometer and there is no additional charge.
• Fully equipped: cross laser fixation, fine-tuning platform for precise alignment.
• User-friendly interface: Simple and easy to use.
• Value-added measurement at ultra-low cost: Glare can be measured with simple equipment.
• It has a wide range of applications.

■ Main Applications

• High-precision measurement of spatial light distribution curves (photometric distribution) for various LED lighting fixtures (semiconductor lighting fixtures), street lighting fixtures, indoor lighting fixtures, and outdoor lighting fixtures.
• The luminous intensity of light sources and luminaires of various sizes can be measured using the most accurate methods confirmed by the CIE.
• Measurement software that meets international standards can directly output test results in internationally recognized standard formats such as IES (American Standard) and LDT (European Standard).
• It can measure the color distribution, average color characteristics, and spatial color non-uniformity of various light sources and lamps.
• It can perform spatial brightness distribution testing for various light sources and lamps.
• Lighting fixtures can be designed based on the measured light pattern.
