Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to better understand the advantages and features of the present invention, and to define the scope of the present invention more clearly.

Example 1:

a projector, as shown in fig. 1-3: the LED lamp comprises a lamp body 1 with an installation space, and a light source component 2, a Fresnel lens 3 and a glass cover plate 4 which are sequentially installed in the lamp body 1 from bottom to top, wherein the light source component 2 comprises an LED lamp bead 21; a mounting bracket 5 for fixedly mounting the lamp body is arranged at one side of the lamp body 1.

Because the utility model discloses a projecting lamp is used for high tower class building, consequently, this projecting lamp is long-range face light, so the utility model discloses in, selected fresnel lens 3's diameter is less than 150mm, and the diameter less than or equal to 35mm of its light emitting area, its luminousness are greater than 90%.

The diameter of the light emitting surface of the Fresnel lens 3 is increased along with the increase of the power of the LED lamp bead 21, and the distance between the light emitting surface of the Fresnel lens 3 and the light emitting surface of the LED lamp bead 21 is increased along with the increase of the power of the LED lamp bead 21.

Because the utility model discloses a projecting lamp simple structure, the volume is less, and to the high tower of co-altitude, in order to reach the irradiation requirement, the power variation range of LED lamp pearl 21 of light source subassembly 2 is 5W-80W, the diameter variation range of the light emitting area of fresnel lens 3 is 2mm-35mm, the interval setting range between the light emitting area of fresnel lens 3 and the play plain noodles of LED lamp pearl 21 is 35mm-45 mm; the specific distance between the light emitting surface of the fresnel lens 3 and the light emitting surface of the LED lamp bead 21 and the diameter of the light emitting surface of the fresnel lens 3 need to be adjusted and determined according to the height of the tower and the power of the selected LED lamp bead 21 of the light source assembly 2.

The utility model discloses in, installing support 5 includes fixed plate 51 and the fixed bolster 53 of fixed mounting in lamp body 1 one side, extends the fixed block 52 of perpendicular to fixed plate 51 to the opposite direction of lamp body 1 along the both sides of fixed plate 51, and fixed bolster 53 with fixed plate 51 looks remote site and fixed block 52 articulated, fixed bolster 53 with fixed plate 51 back of the body end fixed mounting on the object that needs to install lamp body 1 mutually.
