Detailed explanation of the seven commonly used test methods in the LED industry

1, high temperature and high pressure and its impact test:
Target: LED lamps (finished lamps with LED Driver)
Reference standard: industry experience Test method:

1. Place 5 LED lamps in a room with a room temperature of 60 ° C;
2. Adjust the input voltage of the LED lamp to 1.1 times the maximum rated input voltage through a voltage regulator;
3, turn on the power, light 24H, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena;
4. After the lighting test, the impact test is carried out in this environment through the relay control lamp. The test setting is: lighting for 20s, extinguishing for 20s, and cycling for 100 times.

Testing requirements:

A. After the high temperature and high pressure test, the lamp can not be exposed, such as paint stripping, discoloration, cracking and material deformation.
B. After the impact test, the lamp cannot be electrically anomalous such as electric leakage or lighting.

2, low temperature and low pressure and its impact test:
Target: LED lamps (finished lamps with LED Driver)
Reference standard: industry experience
Test Methods:

1, the 5 LED lamps are placed in a -15 ° C environment;
2. Adjust the input voltage of the LED lamp to 0.9 times the minimum rated input voltage through a voltage regulator;
3, turn on the power, light 24H, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena;
4. After the lighting test, the impact test is carried out in this environment through the relay control lamp. The test setting is: lighting for 20s, extinguishing for 20s, and cycling for 100 times.
Testing requirements:

A. After the low temperature and low pressure test, the lamp can not be exposed to paint, discoloration, cracking, material deformation and other abnormal phenomena;
B. After the impact test, the lamp cannot be electrically anomalous such as electric leakage or lighting.

3, normal temperature and pressure shock test:
Target: LED lamps (finished lamps with LED Driver)
Reference standard: industry experience Test method:

1, the 5 LED lamps are placed in a room temperature of 25 ° C;
2. Turn on the power supply according to the rated input voltage of the LED lamp;
3, through the relay control lamps under normal temperature and pressure test, the test settings are: lighting 30s, lights out 30s, cycle 10,000 times.
Testing requirements:

A. After the normal temperature and normal pressure impact test, the lamp can not cause electrical anomalies such as electric leakage and lighting.

4, temperature cycle test:
Target: LED lamps (finished lamps with LED Driver)
Reference standard: industry experience Test method:

1, the 5 LED lamps are placed in a test box, the temperature of the test box can adjust the temperature change rate;
2. Turn on the power supply according to the rated input voltage of the LED lamp;
3, the temperature range of the test box is set from -10 ° C to 50 ° C, the temperature shift rate: greater than 1 ° C / min, but less than 5 ° C / min;
4. The test box is kept at 0.5H for high temperature and low temperature, and is circulated 8 times.

Testing requirements:

A. After the temperature cycle test, the lamp can not be electrically anomalous such as leakage or lighting.

IP66 / IP67 waterproof d-sub connectors-Designed for IP Performance

ANTENK has developed IP66 / IP67  waterproof d-sub connectors that utilize a proprietary sealing technology, which maintains the same physical size and footprint as standard d-sub products.

Antenk's line of  Waterproof d-sub connectors utilize an innovative sealing technology eliminating the need to redesign enclosures and PC boards when implementing IP67 design upgrades.These connectors are designed for applications that require protection from heavy spray or are exposed to short-term submersion. Connectors are available in vertical and right angle board mount types as well as solder cup for panel mount cable applications. Standard D-Subs are available in 9 pin , 15 pin , and 25 pin positions, and high density D-Subs are available in 15 pin, 26 pin, and 44 pin positions

Applications of Antenk waterproof d-sub connectors:
Hand held computers, scanners, and printers that are used outdoors
Remote sensors, gauges, and data loggers that are used outdoors
Industrial and Medical equipment that is routinely subject to wash down
Transmitters and emergency beacons that are subject to temporary submersion
Gas, Electric, and Water metering systems that have embedded Smart Grid electronics
Portable electric generation equipment (Gen Sets)
Consumer and Commercial boating electronics (Radios, Scanners, Radar, DC Power Ports)
