Abstract
The utility model discloses a simple LED optical-electrical characteristic testing apparatus including a microprocessor, and an D/A and an A/D arranged inside the microprocessor. the D/A is successively connected with a constant current drive circuit and an LED lamp to be tested, the A/D is connected with the LED lamp to be tested, the LED lamp to be tested is connected with an optical testing module, and the optical testing module is connected with the microprocessor. The testing apparatus is used for testing the volt-ampere characteristic of an LED, and the LED characteristics of luminescence intensity, correlated color temperature, and dominant wavelength. The whole system is concise and intelligent, and the cost is low; and special apparatuses such as an expensive spectrum analyzer can be replaced by the testing apparatus provided in some field of LED research and application.
Description
Technical field
The utility model relates to a kind of simple and easy LED photoelectric characteristic proving installation.
Background technology
LED(Light-Emitting-Diode), i.e. light emitting diode,, energy-saving and environmental protection efficient with it, life-span are long, high reliability is progressively replacing traditional incandescent lamp, fluorescent light, become lighting source of new generation.National governments all vigorously support the development of white light LEDs, and the developed countries such as U.S., day, European Union all set up special actively implementation by government.Along with the expansion of LED range of application, the user has also had higher requirement to product quality, not only requires the light characteristics such as its luminosity and wavelength to have consistance, and the electrical characteristics such as its forward operating voltage and electric current are also had to strict requirement.Therefore, the testing tool of research LED photoelectric parameter, have an important significance to improving the quality of products, reducing production costs.
Special-purpose LED photoelectric characteristic testing apparatus complex structure, particularly optical characteristic test will be used spectrometer, photometer etc., although instrument has the characteristics that precision is high, but still there is complex structure, cost is high, volume is larger, carry and use very inconvenient, the shortcomings such as system stability is restricted, therefore this instrument can only rest on large-scale analytical test experiment, and range of application is difficult to expansion.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, volume is little, cost is low simple and easy LED photoelectric characteristic proving installation.
For addressing the above problem, the utility model adopts following technical scheme:
