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 display and image light sources for electronic devices, including information and communication devices. 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. .

Since the LED chip is a semiconductor device, it may be affected by the environment of the place where it is used, and there is a problem that performance degradation may occur and the life may be shortened when used for a long time in a poor environment. For example, when exposed to a high temperature and high humidity environment for a long time, the resistance increases, and a lot of heat is generated, and local short may be generated by moisture.

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. Such a huge heat sink has a large weight, which constrains the use space and increases the manufacturing cost. In general, LEDs are manufactured by die-casting heat sinks equipped with heat dissipation fins to be boxed on the back of the PCB to fix them. Therefore, production costs are high and the coupling process between the PCB and the heat sinks is high. Complicated, there is a problem that the heat radiation efficiency is lowered because the heat radiation is made only in one direction. Moreover, if the LED chip fails and does not operate normally, it is impossible to replace the LED chip alone because of the coupling between the LED chip and the heat sink.

In addition, the general LED chip is showing a limit to the irradiation angle, and to compensate for this, to arrange a plurality of LED chips to secure a wide irradiation angle by changing the irradiation direction, but the manufacturing process is complicated and to adjust the optimal angle Not only is it easy, but there is a problem in that a light source has a limitation in the coverage of light and waste of light.

On the other hand, in the case of a light source, a variety of outputs are required according to its use, and general LED lamps have a disadvantage in that they are manufactured separately for each use because the output is fixed and cannot correspond to various uses. These products are not able to expand and contract output, so there is a limit in elasticity and variability depending on the situation.

15A to 15C are perspective views showing an example of a heat dissipation mechanism for a general LED.

Typically, after manufacturing the heat radiating mechanism as shown in Figure 15a through a process such as die casting, in order to improve the heat dissipation performance, the venting slot (S1) as shown in Figure 15b or after forming the venting slot (S2) as shown in Figure 15c ) Is formed by post-processing. However, in the case of manufacturing the heat radiating mechanism as described above, a slot for venting must be separately formed by post-processing, which causes a complicated and cumbersome process.

The present invention has been made to solve the above problems, in particular, so that the heat sink does not need to be boxed in the injection molding method to be able to act independently one by one, not limited to one direction, the heat radiation is carried out in 360 degrees In addition to maximizing the waterproof function of each LED chip, it is possible to realize various shapes and various outputs, and to infinitely expand and angle to realize the LED lamp that can be infinitely extended and the output and irradiation angle can be freely adjusted. And to provide a high power LED engine and a high power LED engine assembly including the same, the output is adjustable.

In order to achieve the above object, a high power LED engine capable of infinitely expanding and controlling angle and output according to the present invention includes a base plate having a flat plate shape; A heat sink bar coupled to at least one edge of the base plate; A plurality of LED chips in contact with one side of the base plate; And an optical lens covering each of the plurality of LED chips.

In addition, the optical lens is formed in a hexagonal shape, provided with a chip insertion groove for inserting the LED chip, is provided to be detachable to the base plate by an optical lens coupling member is the optical lens coupling member When the lens is fixed to the base plate, the LED chip may be in close contact with the base plate.

In addition, the base plate is formed in a disk shape, the circumference of the base plate may be provided with a plurality of heat sink grooves are coupled to the heat sink bar detachably.

According to the present invention, a high power LED engine assembly capable of infinitely expanding and controlling angle and power may include the high power LED engine; It characterized in that it comprises an assembly member coupled to the plurality of high power LED engine to form a predetermined angle with each other.

The assembly member may include a holder to which the high power LED engine is coupled, a first rotational shaft allowing the holder to be rotatable, a support coupled to the holder by the first rotational shaft, and orthogonal to the first rotational shaft. The support may include a second axis of rotation to allow rotation.

According to the present invention, by forming the heat sink in the form of a bar and repeatedly arranging a plurality of the heat sink in the circumference of the base plate, the heat sink is injection molded since it can be easily manufactured by an extrusion method and can be detachably attached to the base plate. It does not have to be boxed in a way to be able to act independently one by one, there is an effect that the heat dissipation can be carried out in 360 degrees not limited to one direction.

In addition, according to the present invention, by covering each LED chip with a hexagonal pillar-shaped optical lens to maximize the waterproof function, there is an effect that can realize a variety of shapes and various output by freely combining the optical lens.

In addition, according to the present invention, the assembly of the plurality of high-power LED engines to configure the omnidirectional angle adjustment, by adjusting the number of each assembly according to the desired output to implement an LED lamp that can be infinitely extended, but the output and irradiation angle can be adjusted freely. It can be effective.

Since the optical lens 20 is formed in a hexagonal shape, when the plurality of optical lenses are properly disposed, the optical lens 20 may be formed in a honeycomb shape, and thus the number of the optical lenses and the LED chips may be adjusted to match the desired output. For example, when the output of one LED chip is 10W, seven LED chips and seven optical lenses covering the same may be combined as shown in FIG. 1 to achieve a total output of 70W.

An O-ring for lens 30 is provided between the optical lens 20 and the base plate 50.

Referring to FIG. 10, the heat sink bar fixing part 126 fixes the lower portion (the power module direction) of the heat sink bar 70. Therefore, since the upper part of the heat sink bar 70 is fixed to the base plate 50 and the lower part is fixed to the heat sink bar fixing part 126, the phenomenon in which the heat sink bar 70 is arbitrarily separated or separated can be prevented. have.
