Preferably, described led light source is installed on the first circuit board, and the madial wall both sides of described base are provided with a pair of first rail groove that is complementary with circuit board, and described first circuit board is fixed in the base by first rail groove.

Preferably, described led light source is red-green-blue LED.

Preferably, described LGP is provided with second rail groove, the madial wall of described base stretches out a pair of location stripe board above first rail groove, described second rail groove is complementary with the location stripe board, and described LGP cooperates the location stripe board to be fixed on the base by second rail groove.

Preferably, described LGP is provided with the location rib, the madial wall of described base stretches out a pair of location stripe board above first rail groove, described location rib is complementary with the location stripe board, and described LGP cooperates the location stripe board to be fixed on the base by the location rib.

Preferably, described first circuit board below connects second circuit board by joint pin, on the described second circuit board circuit control device is installed.

Preferably, described light shield layer is a shadow shield.

Preferably, a pair of hook and/or described base bottom are installed on the described shadow shield and are movably installed with a pair of feet.

Preferably, described electric supply installation is built-in common batteries, battery and/or external rectifier transformer.

Because directly to adopt LED is light source to the utility model, LGP is arranged on the LED top, so the utility model has simple in structure, energy-conserving and environment-protective, is difficult for advantages such as broken, that cost of manufacture is cheap with respect to prior art.

[specific embodiment]

For further detailed elaboration design concept of the present utility model, do further detailed description below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in, the utility model discloses a kind of LED board, comprise base 1, be installed in the led light source 2 in the base 1, the electric supply installation 73 that is electrically connected with led light source 2, and over against the LGP 3 that is installed in led light source 2 tops, described led light source 2 is preferably red-green-blue LED; Described base 1 comprises base plate 1a and the sidewall 1b, the sidewall 1c that extend along the both sides of the length direction of base plate 1a, described sidewall 1b, sidewall 1c extend to form an open slot 11 that is complementary with LGP 3 along the width of base plate 1a, and described base 1 two ends are provided with end cap 51 and end cap 52.Described led light source 2 is installed on the first circuit board 6, base 1 madial wall is provided with first rail groove 13 that is complementary with first circuit board 6, this rail groove 13 can be single, also can be a pair of, and described first circuit board 6 is fixed in the base 1 by first rail groove 13.For further firm LGP 3, can above first rail groove 13, one location stripe board 12 be set along base 1 madial wall, the location rib 91 and the location rib 92 that are complementary with above-mentioned location stripe board 12 are set on LGP 3, certainly also can be provided with and locate second rail groove 14 that stripe board 12 is complementary on the LGP 3, described LGP 3 is by location rib 91, location rib 92 and location stripe board 12 are fixed on the base 1, perhaps be fixed on the base 1 by second rail groove 14 and location stripe board 12, in LGP 3 can be packed base 1 into along location stripe board 12 from a side of base 1, as Fig. 5, shown in Figure 6; Connect second circuit board 7 by joint pin 71 below described first circuit board 6, described second circuit board 7 is provided with circuit control module 72, and this circuit control module 72 can be controlled multiple mode of operations such as led light source 2 variable colors and colour mixture; Described LGP 3 back sides are provided with a light shield layer 4, and light shield layer 4 can be fixed by screw or colloid and LGP, and the two ends of base 1 are separately installed with end cap 51, end cap 52.
