Key points for lighting layout at home

Key points for lighting layout at home

The general standard is that in functional lighting areas (referring to homes), the maximum brightness (referring to environmental and floor brightness) should not exceed 300 lux, and the minimum brightness should not be less than 100 lux. Other spaces can have lower brightness, subject to eye comfort. The control of too bright and too dark scales is related to the environment in which the lighting fixtures are located, just as we can actually feel, large rooms use high brightness lights, and small rooms use low brightness lights, the same principle.

Is the lighting arrangement at home as bright as possible

Is the lighting arrangement at home as bright as possible

The understanding that the brightness of indoor lighting is brighter and brighter is better is incorrect. Both too bright and dim lights are actually not good for the eyes, which also echoes the Chinese saying "too much is better than too much". Because:

Several Key Points for UL Certification of LED Filament Lamps

Several Key Points for UL Certification of LED Filament Lamps

For a long time, LED filament lamps have faced two main problems in obtaining UL certification in the United States: firstly, the lamps must go out after being broken; The second is that the glass shell cannot be broken into pieces, but can only be broken into powder to avoid harm to the human body.

The working principle of LEDs, etc

The working principle of LEDs, etc

Light emitting diodes, like ordinary diodes, are composed of a PN junction and also have single conductivity. When a forward voltage is applied to the light-emitting diode, the holes injected from the P region into the N region and the electrons injected from the N region into the P region recombine with the electrons in the N region and the holes in the P region within a few micrometers near the PN junction, respectively, producing spontaneous emission fluorescence. The energy states of electrons and holes in different semiconductor materials are different. When electrons and holes recombine, the amount of energy released varies. The more energy released, the shorter the wavelength of the light emitted. Commonly used are diodes that emit red, green, or yellow light. The reverse breakdown voltage of the light-emitting diode is greater than 5 volts. Its forward volt ampere characteristic curve is very steep, and when used, a current limiting resistor must be connected in series to control the current passing through the diode.

Introduction to LED lights

Introduction to LED lights

Light emitting diode, abbreviated as LED, is a commonly used light emitting device that releases energy through the recombination of electrons and holes, and is widely used in the field of lighting.
