More specifically, by arranging a pair of lamp assemblies having a symmetrical shape with each other so as to be able to rotate individually about a rotation axis, each lamp assembly is rotated individually so that LED light can be irradiated to a desired irradiation range. Since the irradiation angle can be adjusted freely, the lamp assembly can be rotated individually and appropriately to irradiate the LED light easily and effectively regardless of the installation angle at any angle. There is no need for precise angle adjustment, no need to reinstall for angle adjustment after installation, and it is possible to freely mount or detach the lamp assembly by removing only the extension panel and the rotating shaft.

In general, streetlights on the roadside or on the roof of a building are provided at predetermined intervals to illuminate the road at night. The street light is provided with an illuminance sensor, and when the ambient light is below the threshold, the illumination sensor detects this and turns on the street light. When the ambient light exceeds the threshold, the street light is turned off.

Conventionally, a high-pressure mercury lamp or sodium lamp was used as a light source of a street lamp, and the surroundings were illuminated by irradiating white, yellow, or blue light. However, such high pressure mercury lamps and sodium lamps have a problem in that light conversion efficiency is low, various colors cannot be produced, and environmental pollution is a major culprit.

Recently, with the advent of the low-carbon green growth era, the green environment movement is developing internationally. In line with this international trend, the Korean government has also established and actively supports the five-year green growth plan. In addition, there is a need for energy saving in preparation for resource exhaustion and high oil prices.

Among the low-carbon green growth sectors, light emitting diodes (LEDs) are in the spotlight. LED is a new technology that uses semiconductor devices for lighting. Its low power consumption, semi-permanent life, and the ability to produce various colors are also possible. In addition, LED is a product that meets the trend of low carbon green growth due to its high light conversion efficiency, no mercury, and low carbon dioxide emission.

A light emitting diode (LED) is composed of a junction between a p-type and an n-type semiconductor, and is a type of optoelectronic device that emits energy corresponding to a band gap of a semiconductor in the form of light by combining electrons and holes when a voltage is applied. Light emitting diodes have been used as a display and image light source for electronic devices, including information and communication devices, and since the mid-1990s, blue LEDs have been developed to enable full-color display. Light-emitting diodes (LEDs) are widely used in general lighting, building decoration, mood lamps, vehicles, traffic signals, indoor and outdoor billboards, induction lamps, warning lights, light sources for various security equipment, and light sources for sterilization or disinfection. .

In general, the LED chip shows a limit in the irradiation angle, and to compensate for this, a plurality of LED chips are arranged to secure a wide irradiation angle by changing the irradiation direction, but the manufacturing process is complicated and the cost is large because the multiple LED chips are installed. In addition to increasing, there is a problem that it is not easy to adjust to the optimum angle.

In order to overcome the irradiation angle limit of the LED chip, it is necessary to be able to change the irradiation angle of the LED lamp itself, but since most LED lamps are fixed to the frame and cannot be rotated, they are installed at an optimal angle during the installation stage of the LED lamp. It takes a lot of time to go through several trials and errors.

In addition, since a large amount of heat is generated during the driving process of a general LED, a heat sink having a large volume and a weight is attached to the LED to effectively dissipate it. These huge heat sinks are constraining the space used, and are a factor in increasing the manufacturing cost.

In addition, in the case of general LED street light or security light, the desired output is determined in advance and the number of LED lamps corresponding to it is installed, so that the LED street light or security light installed in one place is removed and the desired output is used in another place. Since it is impossible to do so, it is inconvenient to purchase or manufacture LED street lights or security lights separately.

In addition, while using a LED security light in a specific workplace, if a higher output is required for reasons such as a wider workplace space, there is a problem that the installed LED security light should be replaced with a new LED security light.

The present invention has been made to solve the above problems, and in particular, the irradiation angle of the LED lamp can be freely adjusted individually, and infinitely extended LED lamp capable of adjusting the individual irradiation angle that can be infinitely extended according to the desired output And the purpose is to provide a method for producing the same.

The fixing member 104 is screwed to the seating recess 132 and has a c-shape having extensions at both ends to be stably fixed to the seating recess 132. Since the expansion portions at both ends of the U-shape take a flat plate shape, they are stably screwed to the seating recesses 132. Inside the U-shaped, the first lower coupling member 106, the second lower coupling member 108 and the assembly of the upper coupling member 110 is coupled in the form of being inserted.

The first lower coupling member 106 and the second lower coupling member 108 have a plurality of teeth arranged in a semi-circular shape, so as to engage with a cradle (not shown) having a shape corresponding thereto to fix the housing to the cradle, This prevents the housing from rotating arbitrarily with respect to the cradle.

The upper coupling member 110 has a plurality of teeth arranged in a substantially semicircular shape parallel to each other, screwed to the fixing member 104 to fit the first lower coupling member 106 and the second lower coupling member 108. Physics takes a structure.

As such, a plurality of components are combined to form a cradle fixing portion 102 as a whole, so that the stresses in the coupling with the cradle can be dispersed to quickly alleviate an external shock applied to the cradle or the housing. The cradle fixing part 102 is provided in parallel with each other at a predetermined interval so that the cradle can be firmly and stably coupled to the housing.

The circuit box fixing block 120 is formed in a substantially rectangular plate shape, and includes a screw hole for coupling into the housing 100 and a screw hole for coupling with the driving circuit box 122.

The cradle insertion hole 130 is provided at one side of the housing 100 to provide a passage through which the cradle is inserted into the housing 100.

The seating recess 132 is formed in a substantially rectangular shape on the bottom surface of the housing 100, and serves to seat the pair of holder fixing parts 102.

The cover 140 is formed to rotate to open and close the inside of the housing 100. The cover 140 is provided with a vent 142 (see FIG. 3) to quickly dissipate heat generated inside the housing 100 to the outside, so that the outside air and the inside air can be exchanged smoothly.

The connection part 200 is provided between the housing 100 and the lamp assembly 300. The connection part 200 serves as an auxiliary member of the coupling to more firmly couple the rotating shaft 400 to the housing 100.

The lamp assembly 300 includes an LED lamp module 302, a mounting table 310, a heat dissipation fin 320, a hollow 330, and a guide 340. At this time, the guide groove 342 is provided at the end of the guide 340.

One or more LED lamp modules 302 are coupled to the mount 310 according to a desired output, and each LED lamp module 302 includes at least one LED chip and a lens covering the LED chip. The LED chip may be arranged in various forms under the lens. Although not shown, the LED chip is mounted on the PCB, and various electronic circuits and wiring patterns for driving the LED chip are formed on the PCB. The PCB may be formed in a disc shape or a square plate shape according to the shape of the lens. The PCB can be equipped with a single LED chip or multiple LED chips depending on the desired application and output.

The LED chip may be directly mounted on the PCB, and a mixture layer having excellent thermal conductivity such as an Ag / ceramic / epoxy layer may be provided between the PCB and the LED chip. PCB is usually formed of a synthetic resin material, but may be formed of a metal material. Metal PCB has better heat dissipation effect than general PCB. However, due to the trend of high density integration of the LED chip and small weight of the LED module, there may be a limit in dissipating a large amount of heat generated in the LED device, thereby minimizing the risk of damage to the LED device due to heat accompanying light emission. For this purpose, the metal PCB is preferably provided with a heat dissipation member.

A convex lens may be used as the lens on the LED chip. The convex lens improves the optical characteristics of the LED chip and protects the LED chip. The convex lens has an outer curved surface and an inner curved surface, and the curvature radius of the outer curved surface is preferably formed to be smaller than the radius of curvature of the inner curved surface. By using such an optical convex lens method, it is possible to secure a high directivity, high photosensitivity, and a wide range of illumination to enable long-distance illumination.

The hollow 330 is provided between the mounting table 310 and the heat dissipation fin 320 and is formed in a pipe shape penetrating the lamp assembly 300 from one end to the other end. The rotating shaft 400 is inserted into the hollow 330 to allow the lamp assembly 300 to rotate about the rotating shaft 400.

The guide 340 is provided in a flat plate shape at one edge of the mounting table 310. The guide 340 has a shape that is bent at an acute angle with respect to the surface of the mounting table 310, so that the light emitted from the LED lamp module 302 is dispersed in an unnecessary direction even when the lamp assembly 300 is rotated outward. Do not At this time, the guide 340 is preferably provided with a bent portion 344 as shown in FIG. When the guide 340 is formed at a sharp angle directly to the mount 310 without the bent portion 344, the space where the light emitted from the LED lamp module 302 can spread is too narrow to limit the emission of light. Can be added.

The guide groove 342 is provided in plurality at the end of the guide 340. Guide grooves 342 are provided with one pair per one LED lamp module 302. That is, one left and right are formed at an end portion of the guide 340 facing the LED lamp module 302. The guide 340 prevents the light emitted from the LED lamp module 302 from being distributed in an unnecessary direction, and the guide groove 342 allows a small amount of light to be emitted to the outside of the guide 340. The presence of the light concentrated by) can be recognized from the outside, and the light close to a straight line is emitted through the guide groove 342 to create a unique atmosphere.

The lamp assembly 300 is provided with a pair having a symmetrical shape to be spaced apart from each other by a predetermined interval, side by side to enable individual rotation about the rotation axis (400). Therefore, when the LED lamp according to the present invention is used for street lamps, security lamps, work lamps, etc., the pair of lamp assemblies 300 may be individually rotated so that the LED light may be irradiated to a desired irradiation range. It is possible. That is, since the LED lamp according to the present invention is free to adjust the irradiation angle, even if the housing is installed at any angle to the external structure by using a cradle, the pair of lamp assemblies 300 are individually appropriately rotated to properly rotate the LED light in a desired range. Can be investigated easily and effectively. Therefore, the LED lamp according to the present invention does not need accurate angle adjustment at the time of installation, and does not need to be reinstalled for angle adjustment after the installation.

The rotating shaft 400 is inserted into the hollow 330 to allow the lamp assembly 300 to rotate, one end of which is screwed to the housing 100, and the other end of which is screwed to the expansion panel 500.

The expansion panel 500 is detachably coupled to the other end of the rotation shaft 400. The expansion panel 500 is formed in a plate shape, the upper portion is preferably flat, and the lower portion is formed in a curved surface to match the shape connecting the ends of the heat dissipation fins 320 based on FIG. The expansion panel 500 is provided with a coupling hole 510 for coupling with the rotating shaft.

6 is a perspective view illustrating an example in which the number of LED lamp modules is expanded in an LED lamp according to a preferred embodiment of the present invention.

LED lamp according to the present invention is a lamp assembly is inserted into the rotating shaft, the expansion panel is screwed to the removable end of the rotating shaft. Therefore, the lamp assembly can be freely mounted or detached by separating only the expansion panel and the rotating shaft.

Using the lamp assembly equipped with three LED lamp module as shown in Figure 6 it can be very easy to increase the output of the LED lamp for the embodiment of FIG. In this case, since the length of the rotating shaft may be changed according to the number of LED lamp modules mounted on the lamp assembly, it is preferable to replace the rotating shaft together.

If you are using a lamp assembly with two LED lamp modules and want to increase the power, first remove the extension panel from the rotary shaft and then the lamp assembly from the rotary shaft. At the same time, the cover of the housing is opened and the rotary shaft is separated from the housing.

Next, after preparing a lamp assembly equipped with three LED lamp modules and a rotating shaft having a length corresponding thereto, the rotating shaft is coupled to the housing. Then, by inserting a lamp assembly with three LED lamp modules on the rotating shaft and coupling the expansion panel to the rotating shaft, the LED lamp with increased output can be easily obtained.

In this way, the LED lamp can be infinitely expanded by simply replacing the lamp assembly and the rotating shaft while leaving the housing, the connection part and the expansion panel intact.

Next, a method of manufacturing an LED lamp according to a preferred embodiment of the present invention will be described with reference to FIG. 2.

First, each end of the pair of rotary shaft 400 is screwed to the housing.

Thereafter, the circuit box fixing block 120 is coupled to the inside of the housing 100. The reason why the circuit box fixing block 120 is coupled after the rotation shaft 400 is coupled is that once the circuit box fixing block 120 and the driving circuit box 122 are coupled to the housing 100, one end of the rotation shaft 400 is coupled. This is because there is not enough space for screwing the housing 100.

Thereafter, the driving circuit box 122 is screwed to the upper portion of the circuit box fixing block 120.

Thereafter, the pair of mounting brackets 102 are screwed into the housing 100. In the process of coupling the holder fixing part 102 to the mounting recess 132 of the housing 100, the first lower coupling member 106 and the second lower coupling member 108 are attached to the fixing member 104 in one step. After screwing and screwing the upper coupling member 110 to the fixing member 104 in two steps, it is preferable to screw the fixing member 104 to the screwing portion of the seating recess 132 in three steps.

Thereafter, the lamp assemblies 300 are respectively inserted into the pair of rotation shafts 400.

Finally, the expansion panel 500 is screwed to each other end of the pair of rotary shafts 400. Such assembling order may be changed in some cases. For example, the mounting fixture 102 may be screwed first, and then the driving circuit box 122 may be screwed.
