Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Unless otherwise defined, terms (including technical and scientific terms) used in the present embodiments have a commonly understood meaning to those skilled in the art. Further, it will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense.

Referring to fig. 1, the present embodiment provides a method for analyzing illuminance of lighting on a working surface, including the following steps:

step S1 is a step of generating a work surface in response to an input operation by the user.

In this step, the work surface may be generated in at least two ways as follows.

For example, generating a job surface in response to an input operation by a user includes:

acquiring operation surface parameters input by a user, wherein the operation surface parameters comprise the spatial position, the posture, the geometric shape and the size of an operation surface; and generating a working surface according to the working surface parameters.

Alternatively, the job face geometry is generated in response to a drawing and/or editing operation by a user.

In an actually implemented software product, a user can be provided with a generation-surface-related interactive interface.

In the embodiment, interactive interfaces for drawing the operation surface, generating the operation surface, adjusting the operation surface, hiding/deleting the operation surface and adjusting the position parameter of the operation surface are provided for a user to complete the generation process of the operation surface.

In the drawing operation surface interface, a user selects a drawing mode, a mouse can be changed into a drawing style, and drawing can be started by clicking one point in the canvas. Drawing manners of various shapes may be provided, and drawing manners of the selectable work surface include "rectangular drawing", "circular drawing", and "polygonal drawing".

The rectangle drawing only allows drawing a rectangle frame, a first point clicked is a certain angular point of the rectangle, another point is clicked again to be a diagonal point of the rectangle, and one drawing is completed;

the circle drawing only allows drawing a circular frame, the first point clicked is the circle center of the circle, the other point is clicked again to be the radius distance of the circle, and one drawing is completed;

the 'polygon drawing' can draw any polygon, the starting point and the end point are required to coincide, the first clicked point is a certain angular point of the polygon, other clicked points are other angular points, and when the certain point and the starting point coincide, the drawing is finished.

And allowing a plurality of operation surfaces to be drawn in the same house type, wherein the initially drawn operation surface is a semitransparent yellow frame.

In the adjustment operation surface interface, when the user selects the operation surface, the operation surface displays the outer frame.

The operation surface displays three-axis rotation and height patterns, the height of the operation surface can be directly rotated and adjusted through a mouse, and the operation surface can also be adjusted through numerical values in a parameter panel.

Of course, functional options for scaling the work surface may also be provided.

In the hide/delete job side interface, when the user selects a job side, the "hide" and "delete" operation buttons appear. When the user clicks 'hide', the operation surface can be hidden, and the hidden operation surface can be redisplayed in the display and hiding process. When the user clicks 'delete', the job surface can be deleted.

In the interface for adjusting the position parameters of the working face, two parameter setting entries of height and angle are provided for a user.

Height: the height adjustable distance of the working surface is from the ground height to the maximum height of the house type.

Angle: the rotation can be carried out through the X-axis, the Y-axis and the Z-axis 3 axis of the world coordinate system.

The resulting job surface may be rendered in the canvas, i.e., the rendered job surface area is displayed in the layout of the canvas, and the job surface may be displayed under both 2D and 3D views.

And step S2, obtaining light layout data.

The light layout data comprises the position of the light fixture and the light fixture parameters.

In some possible embodiments, the light fixtures in the space where the working surface is located and the positions and parameters of the light fixtures can be directly retrieved from the space design scheme.

In other possible embodiments, the user may perform lighting layout design or illumination design (Li ht i ng Des i gn) at any time, and directly set the luminaire in the model space where the working surface is located as a light source for lighting illumination analysis.

Parameters of a luminaire typically include model, luminous efficiency, power, luminous flux, color temperature, etc.

Step S3 is to acquire the illuminance point pitch of the work surface and determine the illuminance point of the work surface.

In this step, it is usually necessary to obtain the illuminance point distance input by the user.

In some possible embodiments, the user input may be obtained by adjusting the illumination point density interface: the distribution spacing in the X-axis and Y-axis directions of the illumination distribution point world coordinate system can be set. The illumination points are distributed according to the distance set in the x & y directions by taking the default central point of the working surface as a base point until the whole working surface is fully paved. The base point of the working surface can be reset through the mouse, and the illumination points are distributed according to the distance set in the x & y directions until the whole working surface is fully paved.

Or the illumination point spacing can also be automatically calculated, for example:

and according to a preset standard value of the density of the illumination points, the distance between the illumination points is adapted according to the area.

Step S4 calculates position data of the illuminance point.

Since the working surface is generally a plane, the position data of each illumination point in space is easy to calculate, and need not be described again.

Step S5, calculating the illuminance of each of the illuminance points.

Specifically, in the present embodiment, the illuminance of each of the illuminance points is calculated from the lighting layout data and the position data of the illuminance point.

The illuminance calculation of each illuminance point under the irradiation of all lamps can consider the direct illuminance and the reflected illuminance at the same time, and the conventional common methods are selected for calculation, such as a light distribution curve method, an equal illuminance curve method, a point light source point-by-point calculation method, an optical flux transfer function matrix method and the like, and the method is not particularly limited in the application.

In some preferred embodiments, the method may further include:

And step S6, generating and presenting a lamp illumination analysis chart.

In this step, the lamp illumination analysis graph includes one or a combination of a pseudo color graph, a contour illumination graph, and an illumination point distribution graph.

In order to meet the investigation requirements of users on the light illumination analysis results, a pseudo-color map, a contour line illumination map or an illumination point distribution map can be presented independently, and can also be presented in a combined and superposed manner. For example, referring to fig. 2, the illuminance spot distribution map is displayed separately; referring to fig. 3, the pseudo color map and the contour illuminance map are displayed in an overlapping manner to form a pseudo color map-contour illuminance map; or referring to fig. 4, the pseudo color map, the contour illuminance map and the illuminance point distribution map are superimposed to form the pseudo color map-contour illuminance map-illuminance point distribution map.
