We can see the sun because the light given out by sun enters our eyes. The sun, stars, electric bulb, glowing tube-light, torch, fire, and flame of a burning candle, are all luminous objects. They produce their own light and then emit this light. The luminous objects are the sources of light. The objects which emit their own light are called luminous objects. There are two types of objects: (1) Luminous Objects (2) Non-luminous Objects Luminous Objects and Non-Luminous Objects 4.2 Diffuse Reflection or irregular Reflection.4 Regular Reflection and Diffuse Reflection of Light.1 Luminous Objects and Non-Luminous Objects.When taking the type of surface as well as the backsplash into account, lighting experts recommend that the light source be placed at the front of the cupboard, angled toward the back wall in order to create more diffuse and greater illumination of the work surface. Let us look at under-counter lighting in a kitchen that illuminates a shiny surface. We can, however, change or improve the angle in order to obtain the desired effect in terms of reflection of light. There is no set formula to eliminate the veiling effect on a shiny surface.
This light would lose its brightness, however. On the other hand, a dull or matte finish that absorbs most light beams, or an irregular surface that reflects light beams in an irregular fashion, might diffuse light. Thus, a counter crafted from a material that reflects a large number of incident beams might reflect the light source almost perfectly and create a form of blinding ‘spot’ lighting effect. This is what is known as diffuse reflection of light. A number of these beams randomly reflect in multiple directions. However, when a ray of light meets an object, its beams do not all go through the occurrence of specular reflection at a reflection angle that is equal to the incident beam. Along this course, the color of the reflected beam is identical to that of the incident beam. In fact, the beam that shoots through the specular reflection penetrates the surface it touched by barely half a wavelength. Specular reflection exerts an effect on our perception of objects. Still waters are an example of nature’s ability to produce this type of reflection. Specular reflection rarely occurs in nature, but rather in man-made spaces. On a “perfect” surface, the angle of beam radiation is equivalent to that of the incident radiation. To produce specular reflection, surface irregularities need to be smaller than the length of the beam’s radiation, such as in the case of polished metal, glass, plastic or transparent liquid surfaces. The absorption effect is higher because it reduces the reflected light beam’s strength. For instance, consider when light falls on an uneven or irregular surface such as an unpolished or ragged surface. The type of surface on which it is reflected, as well as the position of the light source, affect the secondary beam. It is further reflected at a similar angle. Light reflects on a surface known as specular surface (similar to that of a mirror) at the angle of incidence. In specular reflection, the incident light is reflected into a single outgoing direction. Specular reflection is a type of surface reflectance often described as a mirror-like reflection of light from the surface. However, the lighting layout designer must always consider specular reflection. The reflection of light exists in many types indeed. The beam alters its course once it hits certain types of surfaces. The reflection of lightĪ beam of light that comes to rest on a surface may be reflected in several ways. It is a vital concept in the field of lighting. Specular reflection, also known as veiling reflection, is light reflection from an object or task that obscures details.
