Group LED light array lamp bead density is minimum, and the lamp bead number of five groups of LED light arrays is along central LED light array formed symmetrical.
Further, the lower tie plate both ends of the shell are each provided with a mounting hole.
Further, multiple groups are arranged in successively under the top of the LED light source unit of continued access, top tie plate in the uniform light board
Side.
Further, two groups of LED light arrays of most two sides, lamp bead density are three rows；Two groups of inside LED lamp array column,
Lamp bead density is two rows；Central one group of LED light battle array, lamp bead density are a line.
Compared with prior art, the beneficial effects of the present invention are:
Artificial light source provided by the invention by the design to array of source quantity and structure so that the light that issues of light source with
Sky visual field matches, and to solve the problems, such as that canopy of the heavens sustained height detectivity is inconsistent, keeps measurement result relatively reliable；
LED light module of the present invention uses linear pattern mode, has the advantages that handling ease, convenient for adjustment；Apparatus of the present invention band
There is mounting hole, may be mounted at position corresponding with sky, there is no strict requirements to the position where sky, so that
The position of sky is more flexible, more convenient to use.
