Detailed Explanation of the Invention

[0031] The invention is a method for forming coverage discrete solid angle light beam that is used to achieve unit areas with uniform light intensity, equal illuminance and luminance levels distribution on a basic illumination area (1) which is targeted and evaluated with unit light beams by discrete the main light beam that polyhedral lighting fixture holds, sufficient light is produced, light produced is used only in basic illumination area (1), requirements of basic illumination area (1) are met within standards, uniform illuminance and luminance levels are obtained through distribution of light at uniform intensity in basic illumination area (1), besides, no regions with weak light intensity or dark regions remain in basic illumination area (1), tetragonal light spots cover on basic illumination area (1) combines each other tetragonal modularly, have got uninterrupted integrated and uniform light coverage, sufficient light production is only for main target illumination area (1), no light pollution exists with not leakage light outside target and besides, no direct glare is occurred outside of target since the light sources not seen outside its own scope. For coverage discrete solid angle light beam, firstly it is ensured that basic illumination area (1) is divided into equal unit illumination areas (3) as many as unit light sources (2). Afterwards, a point at enough height that basic illumination area (1) is to be illuminated is selected as reference point (4) and a reference sphere (5) centered reference point (4), with a radius length enough between basic illumination area (1) and selected reference point (4) is formed. After reference sphere (5) is formed, it is ensured that perspective projection appearance (6) pertaining to unit illumination areas (3) are generated over the reference sphere (5). Later, it is secured that center of unit illumination area (3) and selected reference point (4) merge and axis of unit light axis (7) is obtained. Then, unit light source (2) locations over the reference sphere (5) at equal distance to diameter of reference sphere (5) and beyond reference point (4) in the direction of unit light beam axes (7) are determined. Following this stage, unit light beam solid angle (8) that sets out from the unit light source (2) position and moves ahead by embracing the boundaries of the projection appearance of the unit illumination area (3) on the reference sphere (5) and determines the boundary edges of unit illumination area (3) by its side surfaces. With repetition of abovementioned action steps, it is made sure that unit light beam axes (7) and unit light beam solid angles (8) that cover other unit illumination areas (3) are formed. With formation of unit light beam axes (7) and unit light beam solid angles (8), it is ensured that coverage discrete solid angle light beam is created for basic illumination area (1) and uniform light intensity, uniform illuminance and luminance levels and a homogenous lighting skill are obtained over the basic illumination area (1) accordingly.

[0032] It is concurrently secured with this invention that light axes of unit light source (2) pass through reference sphere (5) centre and intersection point of light axes are generated on sphere (5) centre, unit light beam solid angles (8) take shapes according to projection appearance (6) of unit illumination areas (3) formed over the reference sphere (5).

[0033] Again, with selection of location positions of unit light source (2) on the reference point (4) being intersection point of light axes and at equal distance within the scope of the invention, it is supplied that position planes of unit light source are able to intersect each other, so a polyhedral body may be created and multi plane body formed fixture has concave structure to reference point (4) and the unit light sources (2) deployed on each plane make convergent radiation by mentioned reference point (4) with unit lighting beams they produce in the direction of emitting axis (normal of the plane it settles on) because of their positions. With choice of unit light source (2) location positions on intersection point of light axes and at equal distance, it is provided to determine body structure of illumination fixture as a part of the invention. Unit illumination sources (2) that constitute the lighting fixture are located on reference sphere (5) within this invention.

[0034] On account of making convergent illumination to reference point (4) by unit light beams, it is secured to form a light disk (9) by intersecting on the plane formed parallel to basic illumination area (1). The space covered by this light disk (9) which are formed due to making convergent radiation to reference point (4) by unit light beams become smaller than the volume that polyhedral lighting fixture occupied in space. In addition, this light disk (9) may also be employed as light source instead of polyhedral lighting fixture too.

[0035] Another specification of the invention is that unit light beam solid angles (8) pass from intersection point of axes which is reference point (4) and independently cover their own unit illumination area (3).

[0036] Again, Light sources (2) producing unit light beams which constitute coverage discrete solid angle light beam may be fed with the values different from each other, so desired equal flux values may be created separately by them, and unit illumination areas (3) may be covered by unit light beam solid angles (8) which take form according to unit illumination areas (3) and owing to all these reasons, equal photometric threshold values may be achieved on unit areas.

[0037] With taking shape as per their perspective views in unit light sources (2) of unit illumination areas (3), unit light beam solid angles (8) and the different perspective views in unit light sources (2) of unit illumination areas (3), it is maintained to form unit light beam solid angles with a structure different each other.

[0038] Another key feature within this invention is that the uniform photometric threshold values possessed by unit light beam solid angles (8), the light flux at desired value carried in it and the solid angle shape which is different from others of unit light beam may be obtained both in unit light source (2) and on the unit illumination area (3) it targets with desired values independently from each other.

[0039] With respect to matrix representation for determining location position addresses of light sources (2), while position addresses of unit light source (2) in the polyhedral concave lighting fixture are defined in line index, position elements of unit illumination areas (3) creating basic illumination area (1) are targeted in column index.
