Description

LED lighting module and lighting lamp using it

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED lighting module using an LED (Light-Emitting Diode) as a light emitting device and a lighting lamp using the same. More particularly, the present invention relates to an LED lighting module When a polygonal illumination lamp is constructed by combining the LED module with the LED module efficiently, the light distribution is wide by 180 degrees through the plurality of illumination modules, and by the protruding blades formed on the left and right sides of each illumination module, Since a large number of ventilation holes for heat radiation are formed on the left and right sides of the lamp, the light efficiency and lifetime are stably maintained for several tens of hours or more regardless of the direction of use of the lamp, .

LED lighting lamps are energy-efficient and have a long lifespan, and are quickly replacing lighting fixtures that use conventional light sources such as fluorescent lamps and incandescent lamps. The LED device used for the LED illumination lamp has advantages such as low heat generation, low power consumption, long life and impact resistance as compared with the conventional illumination light source. In addition, since mercury or a discharge gas is not used in the manufacturing process like a fluorescent lamp, there is an advantage that it does not cause environmental pollution.

If the LED device provides adequate power supply and heat dissipation means, it can maintain the lighting state without burning even if used for over 100,000 hours. Since all light sources decrease in light output over time, people do not feel up to 80% of the initial luminous intensity, so the life expectancy of LED devices is expected to be about 40,000 ~ 50,000 hours . Therefore, compared with 1,500 hours of incandescent lamps and 10,000 hours of fluorescent lamps, LED devices have a long lifetime and can be said to be light sources.

However, if the driving current is increased in the LED device in order to obtain an economical light source for high luminance and high output power, the power loss of the LED device increases, so that most electric energy is converted into heat and the junction portion of the LED device becomes high temperature. The LED device has characteristics such that the light output and the light efficiency are lowered and the operation life is reduced if the temperature of the junction part is increased even if the current flowing is constant. Therefore, in order to improve the illumination performance and the operating life, the heat generated at the junction portion of the LED element must be discharged to the outside as soon as possible.

Generally, a light bulb type LED lamp having a small size and a small internal space is structurally disadvantageous to dissipate the heat emitted from the LED element to the outside than other types of illumination lamps. Therefore, it is difficult to obtain a high-intensity illumination light source because mounting a large number of LED elements in a bulb-like or compact-type illumination lamp to increase the light output limits the mounting area and the heat radiation area. Heat is easily accumulated in the inside of the lamp, and the light of the LED element, which is a light source, is changed and the life is shortened.

Also, in a general LED lighting lamp, a high luminance LED element is arranged on a front surface of a heat dissipation frame in which a plurality of cooling fins are formed to constitute a light emitting portion, and a milky white diffusion cover is placed on the light emitting portion to reduce glare. However, in such a system, the light distribution of the light emitting portion is narrowed in all directions, so that the difference in illumination during illumination is significant. In addition, since the light loss is large due to the dark milky white diffusion cover, the illuminance is lowered and heat accumulation occurs inside the diffusion cover. .

Further, since a circuit board having a plurality of LED elements arranged on the entire surface of the heat dissipation frame is mounted, the mounting area is limited, and a large number of LED elements can not be arranged. Therefore, in order to obtain a large amount of light with a limited quantity, expensive high- Or the size of the heat radiation frame must be made larger, so that the lighting lamp becomes bulky and bulky, and the manufacturing cost is increased and the cost is increased.

Therefore, in order to expand the environment of power saving and environmentally friendly LED lighting by replacing existing incandescent lamps and compact fluorescent lamps, it is necessary to increase the light efficiency of LED lamps and to provide a light-emitting device which is lighter, more efficient and economical .
