Street light having angle light source {Streetlamp having illuminant for adjust to the angle}

The present invention relates to a street lamp having a light source for adjusting the angle, and more specifically, it is possible to freely adjust the angle of the light source according to the situation can reduce the damage of the crops due to the night light only by adjusting the angle of the light source without a light screen at night, The light distribution angle can be freely adjusted to the desired place according to the need, and it can effectively light not only the roadway but also the sidewalk, so that it is possible to easily illuminate the sidewalk and the roadway with lower construction cost and simple operation. will be.

Generally, street lights are installed at both sides of the road at regular intervals to secure a driver's watch of a vehicle running at night, and these street lights are turned on from sunset to sunrise. In order to turn on these street lights, the manager operates the lights on the control panel, the lighting is turned on and off.

These streetlights have a highway-type that bends the ends of the poles according to the type of pole, and has a bracket on the back of the poles, extending horizontally to the ends of the poles. It is appropriate to select and install a head hung type lamp etc. according to the installation place.

In addition, the installation height of the street lamp is installed around 9m so that the light emitted from the lamp shines on the road relatively broadly. Since the street lamp is made of electric poles and street lamp holders, the lamp light is irradiated at an appropriate angle according to the road conditions. There is a problem that can not be installed, and furthermore, the light is irradiated to the crops adjacent to the road to mature the crops earlier than the maturity.

Such lighting at night has many advantages for people, but it has more disadvantages than plants, and the degree of damage caused by night lighting varies according to lighting time, illumination, light source (light wavelength), lighting time, temperature, and crop variety. In the case of single plants (flower varieties of rice and beans, perilla, sesame seeds, etc.) that bloom only when the daytime is shorter than the nighttime, the yield and flowering are delayed when the lights are illuminated at night, and the quantity decreases due to poor ripening and fruiting. On the other hand, long-day plants that bloom only when the daytime is longer than the night time (barley, wheat, rapeseed, spinach, etc.) had a problem that the yield and growth was shortened because the outflow and flowering was rather fast, and the yield was reduced.

The present invention is to solve the above problems, it is possible to freely adjust the angle of the light source according to the situation can reduce the damage of the crops due to the night light only by adjusting the angle of the light source without a light screen at night, if desired Its purpose is to provide street lights with angle-controlled light sources that can freely adjust the light distribution angle to the place, and effectively illuminate not only the roadway but also the sidewalks at a lower construction cost and easier operation. have.

In order to achieve the above object, the present invention is a street lamp is provided, the lamp street lamp is formed detachably installed between the support of the lamp post;

The lamp housing has a semi-peripheral shape in which the lower portion of the horizontal gourd is horizontally removed, and forms a front housing and a rear housing, and the front and rear housings are formed through the front and rear housings, respectively, through the front and rear housings. A plurality of heat dissipation holes are formed, and left and right shaft holes are respectively formed at left and right centers of the front and rear housings, and an insertion tube having a plurality of bolt insertion holes formed at the rear side of the rear housing is inserted and fixedly coupled by bolts. ;

Plates of aluminum material having a circular plane, respectively located inside the front and rear housings of the lamp housing, and a plurality of heat dissipation fins protrude upward from the upper surface, and one end of the upper surface is screwed together and the other is vertically erected upward. The other end portion is protruded to the outside through the front and rear pivoting grooves of the front and rear housings, respectively, and a rotation fixing bar is fixed to the front and rear housings by cap nuts, and the shafts are fixed to the front and rear housings by cap nuts and nuts on the extension lines of the left and right shaft holes. A shaft insertion hole into which the shaft bolt is inserted into the shaft is formed, and the power line through the waterproof terminal box located on the upper surface is waterproofed with silicon and penetrates to the bottom, and the outer periphery of the front and rear heat sink having an outer thread formed thereon;

A circular plate made of metal, and a plurality of LEDs mounted on the bottom of the lens are energized and connected by the power supply line, protected by a transparent cover located at the bottom, and closely adhered to the bottom of the front / rear heating radiating plate by an O-ring located at the top. And a metal fish cake having a ring-shaped inner screw portion corresponding to the outer screw portion, the metal cover being tightly fixed by a ring nut having a support ring portion for tightly fixing the transparent cover to the bottom face of the forward / backward rotational heat sink;

The plate body, the left and right shaft support for supporting the shaft bolt from the lower side in the front, front and rear left and right, respectively protruding upward, the front and rear illumination ball is formed on the lower extension line of the transparent cover, respectively, the bottom plate fastened to the bottom of the lamp housing It is characterized by having a cover.

As such, the present invention can freely adjust the angle of the light source according to the situation, there is an effect that can reduce the damage of the crop due to the night light only by adjusting the angle of the light source even without a light screen at night.

In addition, if necessary, the light distribution angle can be freely adjusted and maintained to a desired place.

In addition, it is possible to effectively illuminate not only the roadway but also the sidewalk, so that the sidewalk and the roadway can be easily illuminated with lower construction cost and simple operation.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims.
