Abstract

An LED tunnel lamp of a finned radiator with a heat pipe comprises a shell, an LED chip and a drive power supply, wherein, the shell is composed of a U-shaped radiator, a left shell, a right shell and an upper cover plate; the window in the middle of the upper cover plate is provided with an optical glass plate; the LED chip is arranged on the base plate of the U-shaped radiator which is provided with a rectangular heat pipe; working fluid which can be carried out in gas-liquid phase conversion at normal temperature is injected in the heat pipe; and radiating fins are arranged at the bottom of the rectangular heat pipe and the other parts of the bottom of the U-shaped radiator. The LED tunnel lamp has simple and compact structure and good radiating effect, and is suitable for tunnel lighting engineering.

Description

A kind of LED Tunnel Lamp that carries the tab style radiator of heat pipe

Technical field

The utility model relates to electronic illuminating lamp, the LED Tunnel Lamp that particularly adopts tab style radiator and heat pipe to dispel the heat.

Background technology

Occasions such as factory building, tunnel, parking lot, square are often used high-pressure mercury lamp, although high-pressure mercury lamp has the big advantage of brightness, have that energy consumption is big, short two big fatal shortcomings of life-span.The advantage that the LED lamp is low with its energy consumption, the life-span is long replaces the conventional high-tension sodium vapor lamp just day by day.

Chinese patent literature discloses a kind of Tunnel Lamp (CN201193813Y), its heat abstractor is by heat transfer plate, heat pipe and radiator are formed, contain fin on the heat transfer plate, one end of heat pipe is plugged in the heat transfer plate, the other end is plugged in the radiator, radiator contains two groups of fin of installing back-to-back and tube is installed, heat transfer plate is connected with the installation tube with two groups of fin of installing back-to-back by the heat pipe of approximate " L " shape and the heat pipe of horizontally disposed craspedodrome respectively, it has radiating effect advantage preferably, but, have the heat pipe structure complexity, the processing and fabricating difficulty, the problem that manufacturing cost is high.

The utility model content

The purpose of this utility model provides a kind of employing heat pipe and tab style radiator, simple in structure, compact, good heat dissipation effect, is suitable for the LED Tunnel Lamp of the tab style radiator that carries heat pipe installed in the tunnel.

This novel purpose is achieved in that a kind of LED Tunnel Lamp that carries the tab style radiator of heat pipe, comprises housing, and led chip, driving power, housing are by the U-shaped radiator, and left and right housing and upper cover plate are formed; The upper cover plate middle window is provided with an optical flat; Led chip is arranged on the U-shaped housing base plate, and U-shaped housing base plate has a rectangle heat pipe, is injected with in the heat pipe at normal temperatures and can carries out the working fluid that gas-liquid phase transition changes, and spreads all on rectangle heat pipe bottom and all the other positions of U-shaped housing bottom to be provided with heat-dissipating fin.

Compared with prior art, this novel beneficial effect is:

1, heat pipe and heat-dissipating fin integrated setting are on the U-shaped radiator, and it is simple in structure, compact, are convenient to make, processing cost is low.

2, good heat dissipation effect, can satisfy the heat radiation requirement of high-power Tunnel Lamp

Be injected with working fluid in the heat pipe, working fluid is between gaseous state and the liquid state at normal temperatures, very easily gasify and liquefy, in work, radiator is conducted to evenly and rapidly other positions of radiator near the heat of die sites, simultaneously, the fin of radiator also can directly be taken the heating of led chip.

Radiator structure of the present utility model is science more, changes the thermal source shape by installing heat pipe additional, has increased the radiation efficiency of thermal source, utilizes special formed radiator further to enlarge area of dissipation.

3, this novelly has a profile attractive in appearance, is highly suitable for the lighting engineering in tunnel.

Fig. 3 is shown in Figure 2 the novel stereogram that dissects after half.

The specific embodiment

Fig. 1 Fig. 2 illustrates, this novel U-shaped radiator 9, led chip 10, driving power 5 of comprising, and left and

right housing

8,6 and upper cover plate are formed; The upper cover plate middle window is provided with an optical flat 1; Led chip 10 is arranged on the U-shaped base plate of radiator, the U-shaped base plate of radiator has a rectangle heat pipe 11, be injected with in the heat pipe at normal temperatures and can carry out the working fluid that gas-liquid phase transition changes, spread all on rectangle heat pipe bottom and all the other positions of U-shaped housing bottom and be provided with heat-dissipating fin (referring to Fig. 3).Right shell body 6 is fixed on the U-shaped radiator through clip 3, and left shell 8 is connected with the U-shaped radiator through movable button 7.Also be provided with reflection shield 4 in the U-shaped radiator.Also be provided with sealing ring 2 between upper cover plate and the U-shaped radiator.The setting of sealing ring can stop rainwater or moisture to enter in the housing.
