Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0015] Such as figure 1 As shown, an airport runway LED centerline light includes a constant current variable frequency sine wave dimmer 1, an isolation transformer 2, a lamp controller 3, an LED lamp 4, a bottom cover 5 and a surface cover 6, and the isolation transformer 2 primary side It penetrates into the output circuit of the constant current variable frequency sine wave dimmer 1, and the secondary side is connected to the lamp controller 3. The LED lamp 4 and the lamp controller 3 are connected to each other and placed in the bottom cover 5 together, and the surface cover 6 is connected to the On the bottom cover 5 top.

[0016] The surface of the cover 6 is provided with two symmetrical two-way light outlets and drainage grooves.

[0017] One of the two kinds of two-way light outlets corresponds to two parallel-connected red-emitting LED lamps 4 , and the other corr...

Abstract

The invention discloses a runway LED center line light for an airport. The runway LED center line light comprises a constant current variable frequency sine wave light modulator, an isolation transformer, a light controller, an LED (light emitting diode) light, a bottom cover and a surface cover, wherein the primary side of the isolation transformer passes into an output loop of the constant current variable frequency sine wave light modulator, the secondary side of the isolation transformer is connected with the light controller, the LED light and the light controller are interconnected and are both arranged in the bottom cover and the surface cover is connected to the top of the bottom cover. The runway LED center line light has the advantages of long service life, low energy consumption, high lighting effect and simple structure.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED centerline lamp for airport runways. Background technique [0002] At present, the traditional airport runway centerline lights use halogen tungsten lamps as the light source. Halogen tungsten lamps rely on color filters and lenses to control the color and angle of the light, and use the appearance of the lamp to achieve heat dissipation and waterproof, thus meeting the international standards for navigational lighting systems. The control of the brightness level change of the halogen tungsten lamp will use the dimmer, and the dimmer realizes the constant control of the effective value of the output current through the thyristor chopping technology, so as to achieve the purpose of controlling the light intensity level of the lamp. [0003] However, due to the use of tungsten-halogen lamps as the light source, traditional runway centerline lights have disadvantages such as short service life, low...
