LENS ASSEMBLING STRUCTURE FOR LED LIGHTING APPARATUS

The present invention relates to a lens assembly structure for an LED lighting lamp, and in particular, by pre-assembling a lens holder made of an opaque material to the circuit board side and assembling a lens made of a transparent material to the upper side of the lens holder, the assembly operation is simplified and the circuit board during assembly operation It relates to a lens assembly structure for an LED lighting lamp, which can prevent chip damage of the LED lighting lamp, and has an improved structure so as to increase the light emission distance by concentrating the light of the LED lighting lamp and improving the straightness.

In general, in recent years, LED elements have been spotlighted as light sources for various lighting devices. These LED devices have advantages such as low heat generation and power consumption, excellent durability, and long lifespan compared to light sources of conventional lighting devices such as incandescent lamps and fluorescent lamps.

LED lighting has the advantage of not causing environmental pollution problems because it does not use mercury or discharge gas like fluorescent lamps.

LED devices can be used for about 100,000 hours or more if adequate power supply and heat dissipation means are provided. However, all light sources gradually decrease in light output over time. Since people do not feel well up to 80% of the initial light intensity, according to these standards, the lifespan of the LED lighting lamp is expected to be about 40,000 to 50,000 hours.

Therefore, compared to 1,500 hours of incandescent lamps and 10,000 hours of fluorescent lamps, the relative lifespan of LED lamps is evaluated to be very long.

However, in order to function as a light source by itself, the LED lighting lamps developed so far, especially the flat lighting lamps, have been limited to merely replacing conventional incandescent lamps or fluorescent lamps.

That is, the LED lighting lamp has a design limitation of following the shape of the existing lighting lamp, despite the various layout designs of the LED module and the advantage of being able to change the overall shape of the lighting lamp in various ways.

Therefore, the development of unit lighting with unique shapes and shapes is actively being attempted, and the development and dissemination of so-called 'system lighting' that can implement another type of lighting by connecting these unit lightings is urgently requested. have.

The related prior art is disclosed in Korean Patent Publication No. 10-0961236 "LED system lighting and unit lighting used therein" (registration date: 2010.05.26).

This is so that the overall shape can be implemented in various ways by combining the unit lights of the flat shape that are emitted by the LED.

On the other hand, existing LED lighting lamps have the disadvantage that the lifespan is reduced when the ambient temperature rises and is exposed to high temperature because the LDE has a characteristic that is sensitive to temperature and current.

As a prior art for solving this problem, it is shown in Korean Patent Publication No. 10-0820942 "LED lighting lamp" (registration date: 2008.04.02).

This is because a plurality of wings are formed on both sides of the heat dissipation frame in the longitudinal direction, and the circuit board on which the LED is mounted is attached to the bottom surface in the receiving space of the heat dissipation frame so that the heat generated from the LED and the circuit board is efficiently discharged to the outside. is intended to be released.

In the existing LED lighting, a bolt hole is formed on the bottom surface of the heat radiation frame and the circuit board in order to adhere the circuit board to the heat radiation frame, and the bolt is fastened to the bolt hole to fix the circuit board, or the circuit board is heat-dissipated using double-sided tape. It adopts a method of fixing to the bottom of the frame.

However, in the case of fixing the circuit board with the bolt fastening method of the existing LED lighting lamp, after arranging the bolt hole of the heat dissipation frame and the bolt hole of the circuit board to be positioned on the same vertical line, there is not only the inconvenience of fastening with bolts, but also the bolt hole. There is a problem in processing the ball.

On the other hand, the fixing method using a double-sided tape has a disadvantage in that since the double-sided tape is positioned between the heat dissipation frame and the circuit board, the heat conduction performance is lowered, so that the heat is not smoothly dissipated.

In addition, in the case of the existing LED lamp, light is not concentrated and scattered, resulting in loss of illuminance.

As disclosed in Korean Patent Publication No. 10-1369422 "LED lighting lamp" (registration date: February 25, 2014), which was previously applied by the same inventor, at least one accommodating groove is formed on one surface, and a plurality of heat sinks are formed on the other surface. a heat dissipation frame formed to be spaced apart from each other; a circuit board which is seated on the bottom surface of the receiving groove of the heat dissipation frame, a plurality of LED lamps are disposed to be spaced apart from each other on one surface, and is made of a material capable of heat conduction; A cover member is detachably coupled to the accommodating groove of the heat dissipation frame through a locking means and is in contact with one surface of the circuit board to bring the circuit board into close contact with the bottom surface of the accommodating groove with a pressing force when in contact.

The cover member is composed of a convex lens to prevent light scattering, but in the case of a transparent material, it is difficult to prevent light scattering, and in the case of an opaque material, the lower surface of the cover member and the chip when combined with the chip of the circuit board. Since it is difficult for the operator to visually check the assembly position of the chip, there is a risk of damaging the chip, which takes a long time for the assembly operation, thereby reducing workability.

Korean Patent Publication No. 10-0961236 "LED system lighting and unit lighting used therefor" (Registration date: 2010.05.26) Korean Patent Publication No. 10-0820942 "LED lighting lamp" (Registration date: 2008.04.02) Korean Patent Publication No. 10-1369422 "LED lighting lamp" (Registration date: 2014.02.25)
