What are the main parameters of the lamp

Whether it is indoor lighting or buying eye-protection lamps for children? All this requires us to have a certain understanding of the light source. Not only must the color temperature, color rendering, and illuminance of the light be confirmed according to the used space of the light source; at the same time, a relatively healthy light source must be selected. Strobe, illuminance, and anti-blue light are all important points to pay attention to.

Led lighting Color temperature

It is a measure of the degree of warmth and coldness of the light. The higher the color temperature, the whiter and colder the light becomes. Sunmory LED lights and fluorescent lights have a variety of color temperatures to choose from. Warm light is a dim light that can be seen by the flesh. The color temperature is 2700-3300K. Natural light is similar to the sun's light. The color temperature is 4000-4500K. You can choose to make yourself comfortable according to the scene. Efficient color temperature.

Led lighting Color rendering

Under the light with color rendering index Ra90+ and Ra80 below, there is a significant difference in the vividness of still life. In daily work and study, the color rendering of Ra95+ is very close to the natural light Ra100, which can accurately restore the original color of the article. When choosing a light source, the color rendering index of Ra80 is just passing, and it is best to choose a light source with a color rendering index of Ra80 and above.

Light intensity

Refers to the luminous flux of visible light received per unit area. Referred to as illuminance, the unit is Lux (Lux or lx). It is used to indicate the intensity of the light and the amount of the surface area of the object being illuminated. The lighting illuminance required in the living room is 150-300Lux; the general study illuminance is 100Lux, but the lighting illuminance required for reading is 600Lux, so it is better to use desk lamps as local lighting.

Stroboscopic

The stroboscopic we often say actually refers to the depth of the fluctuation of the luminous flux of the point light source. The greater the fluctuation depth, the more serious the stroboscopic, which is directly related to the technical quality of the electric light source. Due to the structural defects of the human eye, we cannot distinguish the less obvious stroboscopic phenomenon, but the damage caused by a long time is obvious.

The flicker frequency below 80Hz is also called visible stroboscopic. For stroboscopic above 80Hz, the human eye is not easy to detect. If the eye protection light flashes, our pupils will expand and contract. "Using such a lamp for a long time will cause the eyes to swell and fatigue, which may affect the vision test and flicker. The easiest way is to observe the LED bulb with the phone camera. The quality is not good.

Blue light hazard level

Blue light refers to the high-frequency, high-energy blue-violet light of 400 to 450 nanometers in the spectrum, which is the high-energy visible light in the mouth of ophthalmologists, referred to as HEV (high-energy visible light). The "Performance Requirements for Reading and Writing Table Lamps" stipulates that the color temperature of a table lamp should not be higher than 4000K. The main consideration is the effect of blue energy below 500nm on the body's biological clock and retina in high color temperatures. There are four levels of retinal blue light hazards, namely RG0 (non-risk category), RG1 (low-risk category), RG2 (medium risk category), and RG3 (high-risk category). The "Performance Requirements for Reading and Writing Table Lamps" stipulates that the blue light hazard category should not exceed RG0. It is recommended that children and adolescents use RG0 (non-hazardous) products.
