Description

Street light {A STREETLIGHT}

The present invention relates to a street lamp, and in particular, the power supply and the lamp module are supported so as to be located symmetrically to each other on the left and right sides with respect to the top of the street lamp post, so that the power supply is located in close proximity to the lamp module In addition to minimizing losses, the present invention relates to a street lamp that shortens the length of the wire to reduce short circuiting and resistance.

In general, street lamps are lighting facilities installed along the street for the safety and security of road traffic, and suitable types are used depending on the installation places such as highways, main roads of commercial areas, commercial roads, and residential district roads. There are many types of street lamp poles, including a highway type that bends the end of the pole and has its back at the end, a bracket type that extends horizontally at the end of the pole, and hangs on it. There is a scalp shape with a back on the top. As a light source, a high pressure mercury lamp, a fluorescent lamp, a sodium lamp, an ordinary bulb, etc. are used.

Such streetlights emit white, yellow, or blue light by a light source of a predetermined color. Of course, it may be selected depending on the power efficiency of the street light, the intensity of the light, or the ambient atmosphere.

However, the various lamps as described above have the disadvantage that the user can not artificially adjust the brightness and the diffusion range is determined at the time of the first manufacturing, and also has a disadvantage that the life is very short, the power consumption is increased.

In view of this, in recent years, a high shade light emitting diode is formed by covering a lampshade around a light source of at least one high brightness light emitting diode (LED) and slidably convex lenses in front of the lamp shade. In order to prolong life and minimize power consumption, streetlights or lightings using light emitting diodes have been devised.

However, the following disadvantages are pointed out in using a high brightness light emitting diode.

The light emitting diode has a long life that is semi-permanent compared to the lamps described above. However, since the brightness is determined by a plurality of combinations of light emitting diodes, an ideal arrangement is excluded in manufacturing, and the brightness is provided solely depending on the reflector. There was an inefficient disadvantage.

Existing street lamps are mainly provided with a switching mode power supply (SMPS) that supplies power to the light emitting diodes, and is located inside the bottom of the street lamp post, and has a structure connected to the lamp of the street lamp by wires.

Therefore, as the length of the wire between the power supply and the lamp module increases, the resistance value increases proportionally, and there is a problem in that durability is deteriorated due to not only unnecessary energy consumption but also characteristics of an electronic component that is vulnerable to heat.
