Izmenjava vsebine usmerjenega svetlobnega vira lumena LED žarnice
Kot smo že omenili, so LED luči v bistvu usmerjena svetloba. Čeprav obstajajo večsmerne LED žarnice{0}, so zasnovane tako, da lahko nadomestijo izgubljeno svetlobo. Z drugimi besedami, svetlobni inženirji oblikujejo napeljavo ali žarnico, ki postavi LED čip na različne lokacije, da zagotovi ne-smerno razsvetljavo in prepreči pretirano izgubo svetlobe.

The LED chip itself provides a directional illumination. Conventional light sources such as metal halides, high pressure sodium, fluorescent lamps and incandescent lamps are omnidirectional. That means they glow in all directions. As a result, they work well as a universal light source for the home. However, for specialized commercial and industrial environments such as warehouses, factories, and other commercial facilities, they need reflectors to collect and "collect" light in order to focus it and direct it to where it is available. The problem with reflecting light sources is that most of the light produced becomes unusable, otherwise known as lumen loss. Any internal reflection of more than one reflection effectively loses one lumen of light.

Let's take a metal halide bulb as an example. Like LEDs, they are also popular in commercial and industrial applications. However, unlike LEDs, they are not directional. So consider the particles of light produced by metal halide bulbs. In fact, very few particles are reflected off at least one surface and do not reach the ground. So when a light particle is produced, it is likely to hit the reflector of the light fixture, which then tries to direct it to the floor.

Če to ne uspe, se pošlje v drug del reflektorja svetilke, da ponovi postopek. Na tej točki se vrednost svetlobnega delca izgubi. Dokazano je, da lahko pri tem izgubite do 30 odstotkov svojih učinkovitih lumnov. Vendar, ko uporabljate LED osvetlitev, prejmete večino, če ne vse, njenih svetlobnih delcev.

Ko imate boljše lumne, potrebujete manj lumnov. Kakovost svetlobe iz katerega koli vira (tudi sonca) se meri z indeksom barvnega upodabljanja (CRI). CRI je lestvica, ki se uporablja za merjenje natančnosti barve, proizvedene pod določenim svetlobnim virom. Seveda so zlati standard Suns z oceno 100. Vse ostale ocene so bile na lestvici od 1 do 100.

The best explanation for light quality is to perform a simple test. Let's compare LEDs with high pressure sodium (HPS) lamps. In our experience, people often tell you that a 20,000 lumen LED is much brighter than a 60,000 lumen HPS. This is because LEDs have a CRI of 70 plus and an HPS of 22.
