Concept of grow lights Optical Radiatio

When we talk about what is the concept of grow lights Optical Radiation( such as how you define the light from desk top grow light/Mini Grow Light ).

Normal People: Light is… Light.

Artist: Light is the medium of artistic expression, the element of creating works, and the express or of artistic forms.

Professional lighting area: Light is a tool to achieve lighting. It is necessary to make good use of the color, intensity, distribution, movement and other characteristics of light to achieve the best and most Economical lighting effects.

As a physical term, electromagnetic radiation is a form of energy that propagates as both electrical and magnetic waves traveling in packets of energy called photons, or quanta.

Light has wave-particle duality: light is both an electromagnetic wave and a flow of photons

Initial theoretical understanding of the nature of light: Huygens’ wave theory (light is a wave propagating in the ether), and Newton’s particle theory (light is a stream of particles traveling in a straight line).

Subsequent physics developed an understanding of the nature of light on this basis, making wave theory and quantum theory unify the wave-particle duality of light.

E=hv

Wave TheoryLight is an electromagnetic wave of frequency v

Light Quantum TheoryLight of a certain frequency corresponds to a photon of a certain energy E

Here h is Planck’s constant. The energy radiation, propagation, and absorption of light are set as a portion rather than a continuous one. The value of the smallest portion is called an energy quantum. Internationally, the value of this minimum energy quantum is called Planck’s constant. 6.626 070 15 x 10-34J s is the third constant among the seven constants of SI.

 

In different application fields, the wave theory of light and the quantum theory of light are used respectively

Wave Theory:

In the reflection, refraction, interference, diffraction, dispersion and other phenomena of light, the wave theory of light is used.

The wavelength and amplitude of light are the main characteristic parameters.

Light Quantum Theory:

In phenomena such as blackbody radiation, electroluminescence, photoelectric effect, and photobiological reactions, the light quantum theory of light is utilized.

The frequency of light and the number of photons are the main characteristic parameters.

When you use decorative grow lights for big plant( more than 1 meter) , this desk grow light head is rotatable, so you could rotate the lamp to above direction, no matter the plants high/ small, the light spreads evenly over the entire surface of the plant
