How to test the quality of indoor LED lighting

　　Indoor Lighting Downlight LED lighting products, light bar, ceiling and other forms, through the LED lighting product testing situation analysis, mainly failed projects focused on four aspects: First, unequal power, LED lights labeled power incompatible with the standard limits power, generally too large, easy consumption; Second, luminous flux lower than what the manufacturer's claim value; third, light loss is too high because of chip quality and other issues; Fourth structure, protection against electric shock and fire and other heat-resistant insulating material failed to make the original lamp protection against electric shock failure, resulting in exposed live parts or cause a short circuit and other safety hazards.

　　There are 3 LED lighting product safety testing: First, dielectric strength, namely anti-pressure capability; Second, insulation resistance and leakage current; Third grounding resistance.

　　Light detection is accomplished by first integrating sphere to measure the performance of LED lamps light color and characteristics of the LED lamps are using large-scale distributed photometer to measure the light distribution, identification of whether light pollution on the surrounding environment. Followed by 3000 hours or 6000 hours of ignition cycles for light color testing, meet the requirements to qualify.

　　For LED lamp life, usually tested by burning approach to life testing, such as LED bulb, lighted 2 hours 45 minutes, put out 15 minutes, even after the general switch 15000 times normal lighted then it is qualified.
