LED energy-saving lamps are a general term for the industry. There are many subdivided products, such as LED Street Lights, LED tunnel lights, LED High Bay Lights, LED fluorescent lights and LED panel lights and so on. The most important thing for a product is quality, and quality control requires reasonable testing methods and standards. Here below we want to share with you five key points of LED energy-saving lamp testing standards:
According to the requirements of the certain product standard, the product should simulate the drop that may occur during the actual use, which needs to fall from the height of 0.91m to the hardboard. The outer casing of the product should not be broken to expose the dangerous parts inside after the drop test. When the manufacturer chooses the materials of the product casing, this test must be done in advance to avoid the loss caused by mass production failure.
Dielectric strength refers to the maximum electric field strength that an insulator can withstand without electrical breakdown, that is, to maintain its non-conductive properties. Electrical breakdown occurs when the electric field strength is higher than the dielectric strength of the insulator, the resistance of the insulator drops drastically and becomes conductive.
If 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.
Due to the limited internal space of LED lamps, in the structural design, we should pay attention 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.
LED Light Under 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 have a risk of changing their physical properties, posing a fire or electric shock hazard.
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.
As a professional manufacturer of LED lights with ISO9001, ZGSM has a very complete quality control system. Before production, we carefully check the quality of raw materials, and we will also strictly control the semi-finished products in production. After the lamp production is completed, we will not only test whether every electrical parameters of each product meet customers' requirements, but also have an aging test of 8 to 24 hours to ensure that the working performance of the LED lights before we deliver them out.

LED means Light-emitting diodes. These are electronic components that use the passage of electrons within the diode's substance to directly transform electrical energy into light. LEDs are significant because they are starting to replace the majority of traditional light sources thanks to their efficiency and low energy consumption.
For the design, manufacture, and distribution of products, there are standards that have been established by international and regional standardization bodies like CIE, IES, and CEN that are widely regarded as industry best practices. The LED lights manufacured by ZGSM are CE, RoHS, CB, UL, DLC, SAA, ENEC certified. The lighting solutions we provide meet the requirements of these standard.
IEC protection Class II power supplies will have a two-wire power cord as opposed to a three-wire power cord with Safety Earth connection.The concentric square symbol or the words "Class II" or "double insulated" are frequently used to identify products having Class II insulation on safety labels.
