Lighting Test Rules: High Pressure and High Temperature Experiment

Original Article: http://www.lisungroup.com/blog/high-temperature-test-and-high-pressure-experiment/

A: High Temperature Test

The main testing equipments: the constant temperature chamber, thermometer, pressure regulator, the voltmeter and clock.

The main test projects: high temperature and low voltage starter, high temperature and safety operation.

Number of tests: 10.

Test methods: Put the lamps and lanterns under test in the constant temperature chamber, connect the circuit, raise the output voltage of the voltage regulator to 180 V (pressure regulator for the lamps and lanterns only power the lamps and lanterns under test), open the power supply of the constant temperature chamber, set the temperature at60℃, open the power source of the lamps and lanterns when the temperature rises to60 ℃, observe whether the lamps and lanterns work normally, and then raise the pressure regulator to 250 V and let it work for 24 hours, watch the experiment result. When meeting the abnormal phenomenon of the damage of the lamps and lanterns or the deformation of the heated materials, the experiment is not qualified.

B: High Temperature High Pressure Shock Initiation Test

The main test equipments: the constant temperature chamber, thermometer, pressure regulator, the voltmeter and clock.

The main test projects: high temperature starting performance and reliability

Number of tests: 10.

Testing methods: According to the above experiment, under the condition of high temperature, raise the voltage regulator to 250 V, switch the lamps for three times and each time interval is no less than eight seconds (8 seconds means that all the capacitance of the lamps and lanterns discharge to reduce the mutual interference), and in the process, lamps and lanterns should not be damaged, otherwise they will be considered as not qualified.

About Lisun Group:

Lisun Electronics Inc. issued her 2012 version product catalog. Due to the LED industry developed this years, Lisun designed and produced a series high accuracy and high quality LED tester.

High and Low Temperature & Humidity Chamber (GDJS-*B): Different size can be chosen. It used for LED lamp test in high and low temperature condition to measure the quality.

System of Goniophotometer (LSG-2000 or LSG-1800): This system is according to CIE, LM-79 & LM-80 and other lighting international standards. The customer can use it for measuring light intensity distribution curve, export IES files for DiaLux software to re-design the lighting products. It is widely used in LED indoor and outdoor manufactory and lab design center.

Instruments for EMC Testing (EMC500 and ESD61000-5): The LED products sell to Europea are request CE certificate, the EMC Test Instruments are used to measure whether meet CE request.

Spectrophotometer (spektrofotometer) & Integrating Sphere Test System (LPCE-1): This system is suitable for photometric and colorimetric measurement of luminaries such as Energy-saving lamp, Fluorescent lamp, HID lamp (high voltage sodium lamp and high voltage mercury lamp), CCFL and LED. The measured data meets the requirements of CIE and IES_LM-79 for the measurement of photometry and colorimetry.

AC and DC Power Supply: Different voltage and current Power supply can be chosen. It make sure the measuring lamp get a stably test condition on power supply.
