What kind of LED is suitable for indoor lighting?

As the fourth-generation lighting source, LED lighting has characteristics such as high luminous efficiency, energy saving, long service life, maintenance-free, high safety and reliability, and environmental protection. Its product quality is also receiving more and more attention from the public.

To this end, the reporter recently interviewed the Changzhou City Product Quality Supervision and Inspection Institute.

The pass rate of safety is 80-90%

According to preliminary statistics, the pass rate of product safety checked from the production enterprises is about 80%; the first pass rate of product safety and performance that the company commissions to inspect is about 70%.

Shi Zhaoyang, deputy director of the National Semiconductor Lighting Product Quality Supervision and Inspection Center, told reporters that LED lighting products are too rapid for their development, and their quality and trends are not optimistic. Indoor lighting LED lighting products include downlights, light strips, ceiling lamps, and other forms. Through the analysis of the inspection status of LED lighting products, unqualified projects are mainly concentrated in four aspects: First, the power is not equal, the power of the LED lights marked Unmatched with the standard limit power, generally large, easy power consumption; Second, the light Tongliang not reach the manufacturer's declared value, generally low; Third, the maintenance rate is not enough, due to the quality of the chip and other issues, the maintenance of light is not High, easy to dark; Fourth, the structure, the protection against electric shock and the heat-resistant and flame-retardant of the insulation material are unqualified, and the original electric shock protection of the luminaire is invalid, resulting in exposed hidden dangers such as exposed live parts or short circuit.

Shi Chaoyang said that China still tests the safety performance and longevity of LED lighting products with reference to the US “Energy Star” testing standard. Other supporting standards and supervision and management methods have not yet been perfected. As a national testing agency, it is now in the early stages. The data collection actively participates in the compilation of the national standard for "Reliability Test Methods for Semiconductor LED Luminaires".

Shi Chaoyang said: "It's not just that the brighter the more beautiful, the better. We should pay more attention to safety. We should choose lamps that have a high degree of protection, good structure, and low color temperature." A lamp consists of a lamp and a light source. To ensure the safety of use, such as the LED lamp is very important to start the power supply, to ensure that its sporadic integrity; light source should have a good light color, its light and color temperature to meet the standard requirements, such as writing lamp should have a low color temperature , high color rendering index, restore the color tone; high-frequency lamp to pay attention to the strobe degree, because the security is controlled by the national mandatory standards, and power, light and other optical characteristics are determined by the manufacturer More LED lights should be considered Blu-ray hazards.

How to detect?

Safety, light source, and longevity can be referred to as "three channels" of LED lighting products.

There are three basic indicators for detecting the safety of LED lighting products: one is the dielectric strength, that is, the resistance to pressure; the second is the insulation resistance and the leakage current; and the third is the grounding resistance.

The light source detection is firstly to measure the light color performance and characteristics through an integrating sphere. For a light fixture, a large distributed photometer is used to measure the light distribution and identify whether there is light pollution to the surrounding environment. Secondly, the light color test is carried out with a 3,000-hour or 6,000-hour light-point cycle, which is considered qualified if it meets the requirements.

For the life of the luminaire, the life test is usually carried out by means of a flash point method, such as bulb lamp, ignition point 2 hours 45 minutes, extinguishment 15 minutes, normal ignition point after 15,000 times of switching, and it is qualified.
