LED energy-saving lamps are a general term for the industry. There are many subdivided products, such as LED Street Light, LED tunnel lights, LED High Bay Light, LED fluorescent lights and LED panel lights. The following Spikes share with you five key points of LED energy-saving lamp testing standards:
1. Drop test
According to the requirements of the product standard, the product should simulate the drop test that may occur during the actual use, and the product should fall from the height of 0.91 m to the hard board. The outer casing of the product should not be broken to expose the dangerous parts inside. When the manufacturer chooses the material to make the product casing, this test must be done in advance to avoid the loss caused by the mass production failure.
2. Dielectric strength
The transparent casing encloses the power module inside, and the transparent casing material must meet the electrical strength requirements. According to the standard requirements, based on the condition of 120 volts in North America, the internal high-voltage live parts and the outer casing (tested with metal foil) should be able to withstand the 1240 volt AC resistance test. Under normal circumstances, the thickness of the product shell reaches about 0.8 mm, which can meet the requirements of this electric strength test.
3. Insulation requirements
Due to the limited internal space of LED energy-saving lamps, in the structural design, attention should be paid to the insulation requirements between dangerous live parts and accessible metal parts. The insulation can be a space distance and a creepage distance, or it can be an insulating sheet.
4. Temperature rise test
The temperature rise test is a mandatory item for product safety testing. The standard has certain temperature rise limits for different components. In the product design phase, manufacturers should pay great attention to the heat dissipation of the product, especially for certain components (such as insulation sheets). Parts that work under high temperature conditions for extended periods of time may change their physical properties, posing a fire or electric shock hazard.
5. Fault test
Product failure testing is a very necessary test item in product certification testing. This test item is to short-circuit or open some components on the line to simulate the failures that may occur during actual use to evaluate the safety of the product under a single fault condition.
