Description

Energy conservation typed delineator

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delineator, and more particularly, to a delineator capable of emitting light of high luminance at low power and greatly reducing power consumption.

In general, when the driver is driving at night, it is difficult to identify the surrounding conditions of the driving vehicle. In particular, when there is no street light around the road of the driving vehicle, it is not possible to identify the road sign as well as the road condition, so that the probability of an accident occurs when driving while ignoring this.

For this reason, signs and delineators using light emitting elements have been developed and used. These road signs emit light only on the part of the road sign that you want to inform the driver. The road sign can prevent drivers from seeing ahead of time.

However, in the case of a sign using a light emitting device, since a large number of light emitting devices are provided, a battery having a large charging capacity is used because of high power consumption, thereby increasing production costs and complicated manufacturing processes.

Therefore, road signs using optical fibers have recently been introduced. As is well known, the optical fiber has a low power consumption and high luminance, and has a good free deformation, and thus can be widely used for various purposes such as various advertisement display boards and road guide displays.

For example, Korean Patent No. 977876 includes: a base plate formed in a pattern in which a plurality of fixing holes are set on a front surface thereof; A light source installed at a rear surface of the base plate; Optical fibers for transmitting light generated from the light source to form a bundle in which one side is bundled by a binding member and having a greater number of strands than the number of fixing holes; Alignment means for aligning the binding portion and the light source so as to inject light into one end surface of the optical fibers; A battery connected to the light source and configured to supply driving power to the light source; And a power generation means connected to the battery and capable of generating power using at least one natural energy selected from wind and solar energy, wherein the optical fibers are classified into at least two groups according to luminance of the other end surface from which light is emitted. The groups have a first group mounted on the base plate so that the other end surface is exposed to the front surface of the base plate through the fixing hole, and a second unmounted on the base plate with lower luminance than the optical fiber belonging to the first group. Disclosed is a light emitting display device including a group.

It is free to install by using natural energy such as solar light or wind power, and by using bundles of more optical fibers than the number of strands needed, it eliminates the optical fibers located at the edges of the bundles. The use of centrally located optical fibers for light emission of the sign has the advantage of minimizing the luminance unevenness.

However, since light is incident from a single light source to a plurality of optical fibers, there is a problem in that the intensity of light emitted from each optical fiber is weak, so that light of desired illuminance or luminance cannot be emitted.

In addition, there is a problem in that the structure is complicated and the casing provided with a solar panel and a sign for receiving sunlight cannot be operated separately.

Accordingly, it is an object of the present invention to provide a delegator capable of minimizing energy consumption by one-to-one correspondence of a plurality of LEDs to a plurality of optical fibers.

Another object of the present invention is to provide a delineator capable of making all luminance of light emitted through an optical fiber uniform.

Another object of the present invention is to provide a delineator capable of efficiently receiving sunlight by separately adjusting the angle of the casing and the solar panel.

The object of the above is that the front surface is opened and the housing space is formed therein; A circuit board mounted in the accommodation space; A plurality of LEDs mounted on the circuit board in a lens support installed on the circuit board; An optical fiber bundle having one end disposed in front of the lens support to face the plurality of LEDs; A focusing lens mounted to the lens support between the LED and the optical fiber bundle to focus light from the plurality of LEDs onto one end of the optical fiber bundle; A sign installed in the front of the housing; A ring-shaped holder installed along an edge of the sign and fixing the other end of the optical fiber bundle; And a protective cover installed at the front of the housing so as to cover the holder and the sign.

Preferably, a bracket fixed to the structure; A panel support rotatably coupled to the bracket and a solar panel installed on the support; And a housing support rotatably coupled to the bracket on the opposite side of the support, the housing support detachably detachable from the housing.

Preferably, the diameter of the light focused by the focusing lens may be equal to or slightly larger than the diameter of the optical fiber bundle.

According to the present invention, since the light of the intensity of the sum of a plurality of LEDs is introduced into all the optical fibers and the light emitted from the other end of the fiber has the sum of the intensity of the plurality of LEDs, the overall brightness is increased, and only a few LEDs are used. Therefore, it is possible to emit a large brightness of light at low power, which can greatly reduce power consumption.

In addition, since light is emitted through a bundle of optical fibers from a single light source consisting of a plurality of LEDs, the luminance of the emitted light is uniform.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is a block diagram showing a delineator according to the present invention, Figure 2 is an external view.

Delegator 100 is composed of a display unit and a support unit, the display unit is composed of the housing 110 and the parts received therein, the support unit is coupled to the housing 110 and fixed to a structure such as a median separator Consisting of parts.

Hereinafter, each component part is demonstrated in detail.

The housing 110 has an opening in the front and an accommodation space formed therein, and a coupling shaft 111 protrudes from the rear thereof, so as to be described later, the housing 110 is detachably coupled to the housing support 140.

Inside the housing 110, a support wall 116 is formed integrally with the housing 110 to support the protective cover 112 at the end.

In addition, the partition wall 117 is formed spaced apart from the support wall 116 by a predetermined distance, and supports the holder 132 and the sign 114 at its end. Thus, the space between the support wall 116 and the partition wall 117 serves as a passage through which the optical fiber bundle 130 can pass.

A through hole 117a is formed at a predetermined interval along the circumference in the middle of the partition wall 117 so as to pass a passage between the support wall 116 and the partition wall 117 in a state where the optical fiber bundle 130 is aligned.

A circuit board 120 (PCB) is installed at the bottom of the housing 110, an electronic component including a battery 122 is mounted on the circuit board 120, and a plurality of LEDs 124 are mounted at the center thereof.

The plurality of LEDs 124 are concentrated to be installed in the lens support 125, but is not specific, but may be installed by gathering about 2 to 4 LEDs.

The lens support 125 may have a reflective film formed on the inner surface of the lens support 125 so that all the light emitted from the LED 124 may be directed forward, and may form a heat dissipation hole in the side in consideration of heat dissipation.

A focusing lens 126 is installed on the front surface of the lens support 125 to focus light emitted forward from the plurality of LEDs 124 at once.

In addition, as shown in the circle of FIG. 1, one end of the optical fiber bundle 130 is disposed to face the front of the focusing lens 126, and one end of the optical fiber bundle 130 is wound by a ring-shaped holder 127. This corresponds to the focusing lens 126.

With this structure, all the light emitted from the plurality of LEDs 124 is focused at one end of the optical fiber bundle 130 through the focusing lens 126.

Since the diameter of the light focused by the focusing lens 126 is equal to or slightly larger than the diameter of the optical fiber bundle 130, the light of the plurality of LEDs 124 is added to each optical fiber constituting the optical fiber bundle 130. The same flows in.

As a result, the light of the intensity of the sum of a number of LEDs flows into all the optical fibers, and the light emitted from the other end of the fiber has the sum of the intensity of the plurality of LEDs, thereby increasing the overall brightness, and using only a few LEDs. As it can emit light with high luminance, power consumption can be greatly reduced.

For example, according to the present invention, when four 10W LEDs are used, the power consumption is 40W, and the light having the luminance corresponding to four LEDs is the same for each optical fiber constituting the optical fiber bundle 130 by the focusing lens 126. Since the light is incident, the luminance of the emitted light can be increased even when the same power is consumed.

In addition, since light is emitted through the optical fiber bundle 130 from a single light source including a plurality of LEDs 124, the luminance of the emitted light is uniform.

On the other hand, the sign 114 is installed to contact the end of the partition wall 117 in the front of the housing 110, the ring-shaped holder 132 is installed along the edge of the sign (114).

The sign 114 is attached to the ultra-high brightness reflector to reflect light of high brightness in response to the light flowing from the outside.

The holder 132 is provided with a hole corresponding to each optical fiber, and the other end of the optical fiber is fitted into this hole and fixed.

2 shows an external view of a state in which a protective cover is omitted, and the other end of each optical fiber 130 is exposed in front of the ring-shaped holder 132.

In this state, a protective cover 112 is installed on the front surface of the housing 110 to cover the holder 132 and the sign 114.

Bracket 160 is, for example, made of a 'b' shape is fixed to the structure, such as a central separator, one end is fixed to the structure by screws or bolts and the other end is provided with a hinge shaft 162.

The panel support 152 and the housing support 140 are rotatably coupled to the hinge shaft 162 in opposite directions, and the solar panel 150 is coupled to the panel support 152, and as described above, the housing support The coupling shaft 111 of the housing 110 is fitted into the coupling hole 141 of the 140.

Since the panel support 152 is rotated about the hinge axis 162, the solar panel 150 can be rotated at an angle that receives the most sunlight, and the housing support 140 is the hinge axis 162. Because of the pivoting around), the sign 114 can be adjusted to the housing 110 at the most visible angle in the vehicle driving on the road.

The thermal energy received from the solar panel 150 is converted into electrical energy and transferred to the circuit board 120, and then converted into direct current through an inverter (not shown) or the like and stored in the battery 122.

Here, when the circuit board 120 and the solar panel 150 are electrically connected by using an adapter, the housing 110 can be easily separated from the housing support 140 when necessary to replace or repair the display unit. User convenience is improved.
