"beneath," "under" and "beneath" a first feature includes the first feature being directly beneath and obliquely beneath the second feature, or simply indicating that the first feature is at a lesser elevation than the second feature.

Some of the advance is made here, as the skilled person in the art can understand, the focus-amplifying assembly, the cutting assembly are already at present belonging to the effect assembly of the relatively common stage lamp. The focusing and amplifying assembly is used for adjusting the definition, the amplification and the reduction of the light spot or the image; the cutting assembly is used for cutting the light beam into various shapes so as to form light spots of different shapes. Therefore, the detailed description thereof is omitted, and the focus-enlarging assembly and the cutting assembly are directly summarized as a whole.

As shown in fig. 1-4, a heat pipe radiator comprises a plurality of heat dissipating fins 3 arranged in an array, a plurality of heat dissipating tubes 2 and a heat dissipating plate 1, wherein the heat dissipating plate 1 is located above the side of a heat dissipating block formed by the plurality of heat dissipating fins 3 and is parallel to the main body of a single heat dissipating fin 3; the radiating pipe 2 is L-shaped; one ends of the radiating pipes 2 are arranged side by side at intervals and are welded in the radiating plate 1 respectively, and the other ends of the radiating pipes 2 penetrate through the radiating fins 3 which are arranged in an array respectively; the surface plane of the heat sink 1 near the fins is provided with a plurality of fixing holes 112.

In the technical scheme, the surface plane of the heat dissipation plate 1 close to the fins is a heat absorption surface 114, the heat absorption surface 114 is attached to an external heating unit, and the heat absorption surface 114 is a rectangular plane with a large area, so that the heat absorption surface is convenient to fully contact and absorb the heat of the external heating unit; then the heat is conducted to a plurality of radiating pipes 2 inside the radiating plate 1, and then conducted to a plurality of radiating fins 3 having a large surface area through the plurality of radiating pipes 2, and then radiated to the outside air.

In one embodiment, the heat dissipation fins 3 are rectangular or trapezoidal. The heat dissipation fins 3 are used for heat dissipation, and the larger the area is, the better the area is, and the heat dissipation fins are generally designed into a rectangular shape or a trapezoidal shape. The general heat dissipation fins 3 are provided with hasps, which facilitate the front and back lapping when a plurality of heat dissipation fins 3 are combined together.

In one embodiment, the heat dissipation fins 3 are made of aluminum. Aluminum is a light material, and in view of heat dissipation efficiency and cost, aluminum is generally used as the heat dissipation fins in the art.

As one embodiment, the heat dissipation plate 1 is made of copper, because the heat dissipation efficiency of copper is fast.

As one embodiment, the material of the heat dissipation pipe 2 is copper, and the heat dissipation pipe in the art generally uses copper in terms of heat dissipation efficiency and cost.

In one embodiment, the top plane of the heat dissipation plate 1 is provided with a concave waterproof adhesive tape groove 111. This waterproof stripe groove 111 is used for waterproof backup because conventional radiators, such as the radiator in CN201620141045.5, an efficient stage lighting heat dissipation system, as those skilled in the art can understand, do not need to directly participate in waterproof, but the heat dissipation plate 1 in this technical solution needs to directly participate in waterproof when used in a waterproof lamp.

In one embodiment, one ends of the plurality of radiating pipes 3 are arranged side by side at intervals, and the other ends are arranged in two layers side by side. As shown in fig. 5, one ends 21 of the seven radiating pipes are arranged at intervals in a straight line, and the other ends are separated into two layers, four of which are arranged at the upper layer 22 and three of which are arranged at the lower layer 23. The upper layer and the lower layer are adopted to achieve higher heat dissipation efficiency.

As one embodiment, the heat dissipating plate 1 is divided into an external portion 11 and a fixing portion 12, the heat dissipating pipe 3 is located between the external portion 11 and the fixing portion 12, and the external portion 11, one end of the heat dissipating pipes 3, and the fixing portion 12 are welded together. The plurality of radiating pipes 3 are welded inside the radiating plate 1 in order to conduct heat more quickly and improve radiating efficiency.

In one embodiment, the external portion 11 is provided with a plurality of semi-circular grooves a113 on a surface opposite to the heat absorbing surface 114, and the fixing portion 12 is also provided with a plurality of semi-circular grooves b123 on a surface close to the external portion 11. The semicircular grooves a and the semicircular grooves b are matched with each other, and the matched circular holes are used for placing the radiating pipes 2.

In one embodiment, the width of the fixing portion 12 is smaller than the width of the external portion 11. The heat sink 1 is now in a "convex" shape, which aims to reduce the cost and the installation difficulty, because when the width of the fixing portion 12 is the same as the width of the external portion 11, the whole heat sink 1 is a rectangular body, and the screws at the locking fixing holes 112 need to be longer to penetrate through the fixing portion 12 and the external portion 11 at the same time, which is equivalent to the installation difficulty.
