Application description of embedded light strip

Embedded linear LED lighting makes the architecture always a priority. The integration of lighting and architecture is the symbol of contemporary lighting design in commercial and institutional environments. The visual needs of residents of commercial buildings are complex. Lighting is a key design element in complex architectural projects. It may enhance or reduce the visual performance and environmental perception of people using the space. In addition to creating a comfortable, effective and safe environment for space users to perform their tasks, lighting must also help to create a comfortable and positive overall atmosphere and contribute to their health and well-being.

From emotion, function, perception and health to economy and environment, commercial buildings such as office buildings, educational facilities, libraries, hospitals and shopping centers put forward a variety of requirements for lighting. Embedded linear lighting provides an overall solution to the challenges faced by commercial lighting. The embedded installation creates a clean overall appearance and supports the architect's intention to condense the environment. Ability to integrate and balance the environment, tasks and accents lighting the lights into a space through linear lighting, which can easily create a flexible space suitable for specific applications and user preferences. The linear layout of embedded lighting can meet the lighting requirements of different types of spaces coexisting under a roof. For example, the office building is composed of various functional spaces, including open office space, private offices, meeting rooms and meeting rooms, video conference rooms, drawing and graphics production rooms, document rooms, reception areas, toilets and corridors. The embedded linear lighting can meet the lighting requirements of all these spaces and create a cohesive appearance for the whole building.

Before the emergence of LED technology, embedded linear lighting has relied on fluorescent lamps. The merit of fluorescent lamp is its perfect scattered light, which can make the light evenly distributed. However, fluorescent lighting is the main cause of light quality decline. Fluorescence technology has lost the color quality of light to obtain good luminous effect. The spectral power distribution (SPD) of fluorescent lamps is supersaturated by blue and green light, and lacks long wavelength radiation. The unbalanced distribution of radiation power in different parts of the spectrum not only causes fluorescent lamps to cast unnatural colors, but also puts humans at risk of disruption of circadian rhythms and subsequent health effects due to the presence of excessive blue light in the spectrum. Due to the widespread use of ballasts with poor performance, fluorescent lamps also bring flicker into artificial lighting. Pulsed light can cause headaches and eye fatigue, which exacerbates the deterioration of light quality.

LED lighting brings new life to embedded linear lighting, not only because it is more efficient and longer service life than other technologies. Its flexibility in lamp design and optical control allows seamless integration of lighting and architecture. The embedded linear LED lighting can be deployed as a continuous line system with seamless trunking, or it can be achieved through the installation of separate lamps. The compact size and directivity of LEDs allow efficient extraction and transmission of light in a variety of light distribution patterns. Unlike fluorescent lamps, which have limited switching cycles and will fail prematurely when switching frequently, embedded LED lighting systems can use the excellent controllability of LEDs to release the energy-saving potential of lighting control devices. The combination of sensing, intelligence and network with lighting releases the power of intelligent lighting. The ability of static and dynamic design of spectral output of LED products is a huge development in the field of lighting. The intelligent mixing of multi-channel LEDs can realize the continuous variable correlated color temperature (CCT) adjustment from warm white to cold white. Adjustable white light lighting can independently control color temperature and light intensity, which is a key technology of people-oriented lighting (HCl). HCl provides the overall design of visual, biological and emotional effects of light to support human well-being, performance and health.

The embedded linear LED luminaire has a housing usually made of extruded aluminum or cold rolled steel. The aluminum profile has integrated ceiling/wall trim, while the steel shell is usually equipped with additional aluminum profile trim. There are various versions of decorative parts, which can be installed in stone slab, dry wall (gypsum plaster), gap grille, trapezoidal grille, embedded grille or inverted three-way ceiling panel. The metal shell provides a solid structure and is conducive to the heat dissipation of the optical engine. The linear lighting system (including its housing, LED modules and Optics) is provided in nominal length. Some products have a certain length and can be cut into certain sizes as required. Built in fixtures designed for continuous operation applications are equipped with pre assembled connectors for electrical and mechanical quick connections.

The light sources embedded in linear LED lamps are rigid LED modules or flexible LED strip lamps, which are respectively made of metal core printed circuit board (MCPCB) and flexible printed circuit board (FPCB). Although front-end products may use ceramic LED packages with low heat resistance and excellent color stability, SMD LEDs welded on circuit boards are usually plastic LED packages. In linear lighting applications, color consistency is a crucial detail, because in linear LED array, the color change from led to LED is more obvious. LEDs for linear lighting applications are boxed in a 3-step macadam ellipse to ensure led to LED, board to board, and fixture to fixture uniformity. The degree of accurate color reproduction required depends on the application. Although the CRI (color rendering index) of Ra value in the mid-1980s was considered acceptable for ambient lighting applications, the smaller value of CRI RA must be 90 and the smaller value of R9 must be 25 for task and focus lighting applications. Commercial lighting usually uses light sources that display CCT in the range of 3500 K to 5000 K. The adjustable white light lighting system is equipped with multiple CCT LEDs to provide a continuously adjustable color temperature range.
