Different shapes, different colors, various brands, facing the rich LED lighting products, which one to choose? When the LED lighting products "running" into the public line of sight, how to choose the lamp? How to choose the lamp? One thing to test the ability of consumers. In the face of numerous choices, is it important to pay attention to light effects, or to develop color or to directly choose a big brand?
LED lighting products have many measurement parameters. As consumers may not be able to understand and remember these parameters one by one, but to the greatest possible purchase of good lights, some basic ideas and important when purchasing LED lighting products Indicators should still be concerned and mastered.
Only choose the right one
From the consumer's point of view, the general choice of lights are commercial or household, the first step is to determine the application of the lamp, and then specify the type of product to be purchased, whether to buy a table lamp for reading and writing or an LED grille lamp for office use or Flat light, or ceiling light, down light, etc.
"The first step is of course to determine what lights to buy, and secondly it is best to be able to screen out a few favorite brands, in case the selection is too wide to produce 'selection difficulties'." A business person suggested, "you can go online first." Or look at the physical store."
In addition, consumers often have their own standards and requirements, depending on the application area of ​​the luminaire. “The first focus and demand for lamps in different locations is different.†An industry insider said, “As consumers, such as living room lamps, the requirements will be higher, I will pay attention to light quality, dimming or Decorative, material, etc., and some areas of the lamp, such as the bathroom or kitchen, aisle, the requirements are not so high."
When purchasing LED lamps, the consideration of brand and price will be different depending on the application area. “In areas with high light quality requirements, I may choose some high-end brands, and some regions may choose medium brands. And the products with good price and price will not pursue high," said the industry insiders.
It can be seen that consumers start from different needs and adapt to local conditions. “Only choose the right ones are not expensive.†This consumption concept is still applicable when choosing LED lighting products.
Of course, whether it is demand or lighting concept, these are basic preparations, the most important thing is still behind, how to choose the lights, what is the standard of good lights?
Which indicators should be paid attention to when selecting lights
"A good LED light should be safe and reliable, stable in performance, comfortable in light color and reasonable in price," said a corporate person. From the perspective of shopping, this requirement for LED lights is also very easy to understand. "A good LED light should be considered comprehensively in terms of safety, reliability, comfort, appearance, energy saving and price. This is all The general consumer should focus on the issues." Luo Wenzheng, chief technical engineer of Sichuan Xinli Light Source Co., Ltd. said.
Safety is the first priority. If the safety of the product is too bad, there will be safety hazards such as electric shock and fire during use. The reliability of LED lights is also very important, which is reflected in the manufacturer's warranty on the product. At present, the warranty time of LEDs on the market is from 1 year to more than 3 years. Different warranty times mean different product reliability.
Although safety is a condition that all products should meet, many companies (especially small ones) currently use low-cost materials and solutions in order to seize the market, and safety is less considered. Many products on the market currently have this kind of product. Hidden dangers. There is also a quality assurance issue. "Even if there are low-end manufacturers claiming that the warranty is 5 years, maybe less than two years, the manufacturers have long been closed, and there are many examples." Luo Wenzheng said.
So, how can you buy a product with higher safety and reliability? "Go to a lamp brand store or a retail hypermarket, and buy a product with a certain scale and brand awareness." Common advice from people.
"In addition, you can pay attention to selecting products with relevant product certification, and there are no relevant certification marks on the packaging of the lamp, such as the national CCC compulsory certification mark, CQC and CE and other safety signs." Nanjing Handerson Technology Co., Ltd. Han Licheng, the manager of the department, suggested.
Under the premise of safety and reliability assurance, LED lights still have some indicators to pay attention to. One of them is comfort, including color temperature, color rendering index, glare and strobe.
The color rendering index represents the color rendering ability of the light source to the object. The value is 0-100. The higher the color rendering index, the stronger the color rendering ability of the object. LED lighting for indoor lighting has a color rendering index of 80 or more, which can make the home colorful and perfect. With the advancement of LED technology, many companies' LED indoor lighting products can achieve 80 or more color rendering indexes.
"Generally speaking, table lamps for reading and writing or bedside lamps in the bedroom have higher requirements for color rendering. It should be better at 80 or even 85 or higher. Consumers should pay attention to the color of the lamp when purchasing such lamps. What is the index?" said Peng Wanhua, head of the optoelectronics expert group of the Fujian Optoelectronic Industry Association.
Glare and strobe are also issues that need to be paid attention to when selecting lamps. If the glare of the lamps is not well controlled, obvious glare and bright contrast will affect people's sight, and serious stroboscopic light has potential harm to both psychology and physiology. Can be easily found through the camera lens of the mobile phone." Industry insiders suggest.
The color temperature range of the LED lamp is generally 2700-6500K, the smaller the value is to the yellow light, and the other is the blue and white light. The difference in color temperature gives people a different feeling and atmosphere, and it also depends on the preferences of consumers. It has been concluded that Huang Guang is usually used in winter and bedroom, living room, dining room, etc., to create a warm and comfortable feeling. The white light is brighter and clearer, suitable for summer and study, kitchen and so on.
Luo Wenzheng said that from the US Energy Star or domestic indoor lighting standards, the color temperature of LED indoor lighting products are limited to below 4000K, the best is 2700K. This section of the color temperature blue light spills less, and easy to relax, suitable for rest.
