Color rendering index:
The degree to which the color of an object appearing under a light source is similar to the color appearing under a Planck radiator (with a color temperature below 5000K) and sunlight (with a color temperature above 5000K) is called the color rendering of the light source, expressed in Ra {percentage}. The highest color rendering index is 1000, indicating the degree of "color change" and "distortion" of an object under the tested light source.
Color rendering index at different levels and application locations:
Color rendering<60 has poor effect, suitable for roads/warehouses/large workshops
The color rendering effect is similar to 60-69, suitable for use in corridors and halls
70-79 color rendering effect can be achieved by crucible, applied in factories/schools/supermarkets
The color rendering effect of 80-89 is good, suitable for use in offices/conference rooms/hotels/shopping malls/hospitals
90-100 color rendering effect is the best, applied in museums/printing and dyeing industries/laboratories
luminous efficiency:
Luminous efficiency is the ratio of the luminous flux it emits to its power consumption, measured in lumens per watt (lmw). The higher the value of luminous efficiency, the higher the efficiency of the light source. For places with longer usage times, such as offices, corridors, hotels, etc., luminous efficiency is usually an important consideration factor
Color temperature:
When the light color of a light source is similar to the light color emitted by an absolute blackbody at a certain Kelvin temperature (K), this Kelvin temperature is the light color temperature of the light source, abbreviated as color temperature. Kelvin temperature, also known as K, is a thermodynamic temperature unit and one of the basic units in the International System of Units (SI). Celsius temperature is equal to Kelvin temperature plus 273. 2700K orange color 3000K warm natural color 3500K natural color 4000K cool natural color 5000K daylight color 6500K cool daylight color.
Illumination:
The luminous flux received per unit area of the illuminated surface
The unit is lux (LX), which is the luminous flux received per unit area of the illuminated surface
In equation E=Φ/A
Illuminance on the illuminated surface, lux (LX)
Luminous flux received on the medium/A area (LM)
The area that receives light flux.
Lamp IP protection level:
According to the IEC standard and the international GB7001-86 "Classification of Protection Levels for Lamp Enclosures", the protection level code is composed of IP letters and two characteristic numbers. The first characteristic number refers to the form of protection, and the second characteristic number refers to the level of protection. As shown in the table below:
Lighting design elements:
Based on the usage date and user preferences, taking into account the effectiveness and economy of light (illuminance, efficiency, uniformity), as well as comfort (color temperature, lighting control, brightness control)
Artistry (atmosphere, color rendering, shadows) is achieved by selecting the most effective light source group, reasonable quantity, appropriate configuration layout, and four matched lighting fixtures to meet the best work and life lighting requirements at the most reasonable comprehensive cost.
The Seven Elements of Lamp Selection:
Safety certification: Compliant with lamp head (EC61), lighting fixture (IEC598), and China 3C or US, Canada, and EU certifications.
Material structure: High purity aluminum material, good thickness of the base plate on the lamp, anti glare, and good heat dissipation design.
Surface treatment: degreasing, rust removal, moisture prevention, UV protection, anti-static, positive hardening and oxidation treatment
Installation and maintenance: Easy to install and construct, light source accessories are easy to maintain.
Appearance: Coordinated and aesthetically pleasing with the building.
Cost effectiveness: affordable and high-quality.
Dengxian anti electric shock level:
Class1: The lamp is not only placed on a basic insulator, but also equipped with another safety protective body, connecting the conductive part of the conductor to the safety conductor. (Grounding)
Class 2: In order to prevent electric shock, the lamp is not only placed on the basic insulation, but also equipped with another safety protection body and reinforced double insulation.
Class 3: In order to prevent electric shock, the lighting fixtures are connected to a safety ultra-low voltage power supply, and the high voltage generated below will never be grounded for Class 3 lighting fixtures.
LED energy-saving comparison:
Compared with traditional self tungsten lamps, ED lamps save 85% energy. Additionally, LED has a long lifespan, usually 30000 hours. Through the following energy-saving comparison, we can gain a detailed understanding of the superiority of LED. Energy saving comparison of using different lamps for daily lighting (same brightness 600LM)
Note: The average number of lights used in each household is 10, calculated based on an average of 6 hours of use per day. When using LED lights, there is no flicker,
Energy saving comparison of using different lamps for lighting in small and medium-sized shops that can protect vision (same brightness 600LM)
Note: 1. Calculated based on the lighting electricity consumption of small and medium-sized shops, using 200 lamps per store for 14 hours per day, such as small supermarkets, small and medium-sized restaurants, small and medium-sized leisure centers, medium-sized clothing stores, etc.
For large chain supermarkets, star rated hotels, large enterprises, hospitals, schools, and other places with high lighting electricity consumption, cost savings are even more significant.
