Optical requirements
The basis of light is the “core”: the chip LED determines the quality of the light output of the lamp. It is very important to choose which chip matching. Choosing the LED and the demand parameter standard is the basis and purity to ensure the light quality of the “core” piece, for example You can choose a low-power SMD chip, or the
current hot EMC3030, or an old and strong high-power 3535 package LED lamp bead, which is a matter of learning, and the choice of LED lamp beads should be chosen. Which technical parameter area and so on, which will determine the technical direction of the luminaire and the market sales positioning pattern. Office lighting
standard Ra ≥ 80, then some high-demand office buildings may need to meet 9050 (Ra90, R9 50), if it is industrial warehouse lighting, I think if you want Ra80/90, it is a waste, the standard requirements to reach Ra ≥ 70 is fine. Because the light efficiency of the LED lamp bead is inversely proportional to the Ra parameter, the higher the Ra, the more light efficiency is sacrificed, so the most important is the most suitable.
Light control
Optics is the light control magician of the luminaire. It is a tool for controlling the divergence direction and light intensity distribution of the light emitted by the LED lamp bead. It is commonly known as the magic light control magician. Optical components, whether they are lenses or reflectors, must be combined with the matching LED bead to make sense. So when choosing a scene application and choosing a lighting solution, LEDs and optics must be considered together, and what kind of solution can be used to achieve the lighting effect we want. Then consider the light distribution, efficiency and anti-glare requirements on this basis. According to the IES EN12464-1 standard, the general office scene can meet UGR < 19, preferably UGR < 16, of course, if the glare value of a scene can control UGR < 10, then we basically think that there is no glare.
