The basic method of indoor lighting calculation
1 General
This guideline technical document proposes a basic method, one that does not rely on the standard lamp light distribution and is not limited to the luminaire
General installation method.
This method is called "basic method" because it serves as a basis for applying the method.
This method can be applied in the following areas.
a) The indoor environment is a rectangular parallelepiped;
b) The work surface can be assumed to be the plane of a material and is considered to be an interior surface of the house;
c) The surface of the room is uniformly reflected and complies with Lambert's law, with a ceiling reflectance of R1 and a mid-fin reflectivity of R2 (defined as the ceiling
The part of the vertical plane between the plate and the lamp), the reflectance of the wall is R3 (defined as the vertical surface between the lamp plane and the working plane)
R4 is the working surface reflectance 1);
d) There is no significant change in the direct flux of the working surface if the luminaires are rotated around their vertical axis 2).
2 F4 direct exposure to luminous flux
To define the direct exposure flux of a work surface, it is assumed that the light emitted by the luminaire is conical with an axis coincident with the vertical axis of the luminaire,
And can be expressed as a cone-shaped fourth-order polynomial cube corner function without constants.
In the polynomial, the actual integral with the four solid angle regions π/2, π, 3π/2, 2π3) is given by selecting the specific coefficients belonging to different luminaires
Luminous flux the same exact value. In the proposed method, the luminous fluxes FC1, FC2, FC3 and FC44 of these four regions describe the
Distribution, F is the total light output of the lamp (upper light and lower light).
Under these conditions, the symmetry point light source flux (Fu) obtained from the rectangle vertically above a certain corner of the rectangle is the luminous flux FC1,
FC2, FC3, FC4 linear function.
The weighting factors GM1, GM2, GM3, GM45) are the ratio function X/H of the length of each side of the rectangle to the height of the rectangle from the luminaire
Y/H (see Figure 1). These factors are multiplied by 1000 and are given in Tables I.1 through I.6.
1) The international lighting glossary uses ρ to represent the reflectance.
2) This is the case with most fluorescent lamps and lanterns. In the case of obvious asymmetry, a special calculation method should be used. This method is additional
The report states.
The definition of symmetrical luminaire given by international lighting vocabulary is slightly different. "Illumination with symmetrical light intensity distribution".
3) The half-width limits of the four regions are respectively .41 °, 4 °; 60 °, 0 °; 75 °, 5 °; 90 °, 0 °.
4) FC. Cumulative flux.
5) GM. Geometric multiplier.
