Problems solved by technology

[0004] At present, there are two traditional measurement methods, the four-point method and the center method, among which the four-point method (such as figure 1 Shown) the number of measurement points is large and difficult to select, and there will be a problem of coincidence of road measurement points at the intersection of motor vehicle roads and pedestrian roads
However, the center distribution method is not accurate enough for the calculation and processing of the measurement results.

Embodiment 1

[0022] Then with figure 2 As an example to illustrate this method in detail, first divide the measurement section between two light poles on the same side of the road into a 4×4 rectangular grid of equal size in the figure, then set the measurement point at the center of the grid, and measure each point with an illuminance meter illuminance value. Calculate the average illuminance using the above formula (a)

[0023] Among them, E av is the average illuminance value, E 0 is Figure 1 The illuminance values ​​of the grid measurement points at the four corners of the middle measurement area; E1 is Figure 1 The illuminance value of each grid measurement point at the periphery of the middle measurement area except for the four corners; E2 is Figure 1 The illuminance value of the grid measurement points within the 4 outer sides of the middle measurement area.

[0024] The average illuminance calculation formula in the prior art is a general summed average, as follows:

Abstract

The invention discloses a testing method of illumination intensity for road illumination, which comprises the following steps of: 1, transversely and longitudinally dividing four lamp posts which are rectangularly arranged at the two sides of the road and used as a reference into M*N rectangular units at equal intervals, respectively; 2, respectively detecting illumination values of central points of each rectangular unit, wherein the illumination of the rectangular units where the four lamp posts are located is expressed by E0, the illumination of other rectangular units on the edge is expressed by E1, and the illumination of the rectangular unit in the middle is expressed by E2; and 3, acquiring average illumination by using a weighing calculation method. In the invention, the detection method has the advantages of scientific distribution points, more correct result and higher testing efficiency.

Description

technical field [0001] The invention relates to a method for detecting illuminance, more specifically, to a method for detecting illuminance of street lights and road lighting. Background technique [0002] As a new type of light source, semiconductor light-emitting diode (LED) has many advantages compared with traditional light sources, such as small size, light weight, space saving, wide spectral range, easy design, and low energy consumption. Moreover, it has good reliability and long service life, and has broad development prospects. [0003] With the acceleration of the national urban construction process and the implementation of energy conservation and emission reduction strategies, LED street lamp products will be more and more widely used in practice. Since street lamps are laid outdoors, they have many particularities such as large environmental changes, concentrated power supply time, dangerous test environment, and difficulties in implementing test plans. The qu...
