What’s the three kinds of temperature text for the LED lamp

The high temperature and pressure and impact test:
For objects: LED lamps
Test method:
1, 5 models LED lamps are placed in a room at temperature60 ℃;
2, the maximum input voltage of the LED lamps adjusted is 1.1 times more than the rated
input voltage through the regulator;
3, connect the power , lighting 24H, and observe whether there is damage to the lamp, thermal deformation of materials and other anomalies;
4, the lighting test, through the relay is to control lamp in this environment for impact test, the test is set: as:lighting sup 20s, lighting out 20s, 100 cycles.
Test requirements:
A, lamps after high temperature and pressure testing, the surface can not occur stripping, discoloration, cracking, deformation of the material and other anomalies;
B, after impact test, what can not occur is the leakage current, not lighting and other electrical anomalies.
Second, the low temperature and pressure and impact test:
For objects: LED lamps
Test method:
1, 5 LED lamps shall be placed in a -15 ℃ environment;
2, the minimum input voltage of the LED lamps is adjusted 0.9 times more than the rated input voltage through the regulator;
3, power, lighting 24H, and observe whether there is damage to the lamp, thermal deformation of materials and other anomalies;
4, the lighting test, through the relay is to control lamp in this environment for impact test, the test is set as: lighting 20s, lights 20s, 100 cycles.
Test requirements:
A, lamps after low temperature and pressure testing, what can not occur is stripping discoloration on the surface, cracking、 deformation of the material and other anomalies;
B, lamps after impact test, leakage current can not occur, not lighting and other electrical anomalies.
Third, the impact test temperature and pressure
For objects: LED lamps
Test method:
1, 5 LED lamps shall be placed in a room temperature of 25 ℃ environment;
2, according to the rated input voltage of the LED lamps is to power lighting;
3, through the relay control lamp at room temperature and atmospheric pressure impact test, the test set to: lighting 30s, lights 30s, circulation 10,000 times
Test requirements:
A, lamps after the impact test temperature and pressure, what can not occur is the leakage current, not lighting and other electrical anomalies.
Meanwhile,there are a large number of manufacturers specializing in developing and producing LED light over the world, lead lighting is one of them,Lead lighting has been continuing to strengthen the use of certified raw materials such as  LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the  LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit http://www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click http://www.lead-lighting.com/products/bid32-1.htm for more detailed and professional features and uses of the LED tunnel light or return homepage to take a good look at other LED light.
