Description

LED lighting module and lighting lamp using the same

The present invention relates to an LED lighting module using an LED (Light-Emitting Diode) device as a light emitter and an illumination lamp using the same, and more particularly, to emit light [light-diffusing-heating] in an integrated LED lighting module. This efficient LED lighting module and a polygonal lighting lamp in combination with each other form a wide light distribution 180 degrees in all directions through a plurality of lighting modules, and the lighting module is formed by protruding wings formed on the left and right sides of each lighting module. Economical LED lighting module and lighting lamp using the same as the multiple heat-dissipating vents are formed on the left and right sides of the convection to facilitate convective heat dissipation in all directions. It is about.

LED lighting lamps are rapidly replacing light fixtures using conventional light sources such as fluorescent lamps and incandescent lamps due to their high energy efficiency and long lifespan. LED elements used in LED lighting lamps have less heat generation than conventional lighting sources, and have advantages such as low power consumption, long lifespan, and impact resistance. In addition, since mercury or a discharge gas is not used, such as a fluorescent lamp, the manufacturing process has an advantage of not causing environmental pollution.

If the LED device provides proper power supply and heat dissipation means, it can be kept on even after 100,000 hours of use. The light output of all light sources gradually decreases over time, but up to 80% of the initial brightness is not easily perceived by humans. Based on this, the lighting life of LED devices is currently estimated to be about 40,000 to 50,000 hours or more. . Therefore, the LED element can be said to be a long lifespan light source with a very long life compared to 1500 hours of incandescent bulbs and 10,000 hours of fluorescent lamps.

However, if the driving current is increased in the LED device to obtain an economical light source for high brightness and high output, the power loss of the LED device is increased, so that most of the electrical energy is converted into heat and the junction portion of the LED device is in a high temperature state. Even if the current flowing through the LED is constant, if the junction temperature rises, the light output and the light efficiency are not only reduced, but the operating life is also reduced. Therefore, in order to improve lighting performance and operation life, the heat generated at the junction of the LED device should be discharged to the outside as soon as possible.

In general, LED light lamps having a small size and a small internal space are structurally disadvantageous to dissipate heat emitted from the LED elements to the outside than other types of lamps. Therefore, increasing the light output by mounting a large number of LED elements in a bulb-type or compact-type lighting lamp has limitations in the mounting area and heat dissipation area, making it difficult to obtain a high-brightness lighting source. Heat easily accumulates inside the lamp, causing a problem that the light of the LED device, which is the light source, changes and the life is shortened.

In addition, a general LED lighting lamp is a light emitting unit by arranging a high-brightness LED device on the front of the heat radiation frame formed with a plurality of cooling fins, and made a lighting lamp by covering the milky white diffusion cover to reduce glare. However, in this method, the light distribution of the light emitting part is narrowly formed in all directions, and the illumination intensity difference is severe when illuminating, and the light loss is large due to the dark milky white diffusion cover, resulting in low illumination and heat accumulation inside the diffusion cover. There was a problem of shortening.

In addition, since the mounting area is limited on the front of the heat dissipation frame and the mounting area is limited, a large number of LED elements cannot be arranged, and therefore, expensive high-brightness LED elements are used to obtain a large amount of light in a limited quantity. In addition, since the size of the heat dissipation frame must be made larger, the lighting lamp is heavy, bulky, and has a problem in that it is difficult to disseminate because the manufacturing cost is increased.
