When it comes to buying lamps for decoration, how to judge the quality of lamps?

Lamps

One: Industrial Design - Lamp Body

Different lamp bodies and materials affect the heat dissipation of lamps, such as the spotlight I am holding. The one-piece die-cast aluminum lamp body has a good texture.

spotlight industrial design

4-grid fin radiator is very conspicuous. This design can maximize the heat dissipation area, reduce the working temperature of the light source, and reduce light

This lamp body also supports unilateral 25° angle adjustment, and has an angle reference line

angle adjustment scale mark

This greatly improves the time when the spotlight is washing the wall. Angle adjustment efficiency.

And the direction can be rotated and adjusted. One advantage of this design is that it is convenient when installing the light. If the direction cannot be adjusted and the error is large, the whole thing must be removed and reinstalled. This rotating design is quite user-friendly

From the perspective of industrial design, good lamps must meet the requirements of good heat dissipation, high efficiency, and humane angle adjustment

二: Light source quality - parameter

Color rendering index RA value , is a parameter we often use to judge the quality of a light source

High-quality light source

​The closer the value is to 100, the better, and the higher the degree of color restoration. Many people only know to look at the color rendering index RA, but don’t know that they also need to look at the R9 value in the color rendering index

​

, which represents the color rendering of the red light source. The color rendering index of some lamps is above 80, but the R9 value is still negative, and the color will be dull and blue. Don't choose.

This is a very cost-effective 100-yuan spotlight that I often share. We used a spectrometer to measure its data. We can see that the color rendering index RA is 97.7, and the R9 has also reached 92.

High-quality lamp parameters

Parameters commonly used to judge the quality of light sources are - Blue light index

National standard GB/T20145-2006 "Photobiological Safety of Lamps and Lamp Systems" document stipulates that blue light with wavelengths between 00nm-500nm can damage our eyes. In this wavelength range, it is not acceptable if the peak is too high

Blue light index

Because the above values ​​may be too professional and are limited by the lack of professional instruments for measurement, you can ask the merchant for these parameters. Another way is to look for the 3c (national standard), ce (European Union standard) and other certifications on the lamp packaging.

Lamp certification

​ Large certified brands are basically qualified for eye protection requirements. So don’t buy uncertified lamps.

I will share so much today. Here is the village chief
