Description

LED factory etc. {LED Factory Lamp}

The present invention relates to a factory, and more particularly to a factory, a large warehouse, an athletic facility, or a large-sized shopping mall, which is suspended from a used ceiling and has an LED module installed radially, An LED factory which irradiates light to illuminate the interior of the body, and a heat dissipating part is integrated.

In general, the luminaire used for lighting is used in various forms such as a fluorescent lamp, an incandescent lamp, a factory lamp, a street lamp, and a security lamp. In recent years, LEDs have been widely used because of their advantages such as low power consumption and semi-permanent lifetime.

The lighting device using the LED mainly uses a substrate on which a plurality of LEDs are mounted. However, since the LED generates a large amount of heat due to a high heat generated by the LED, there is a limitation in increasing the power consumption, there was. For this reason, a lighting device using a conventional LED basically adopts a heat dissipation structure.

Conventionally, a heat dissipation structure having a structure such as a heat dissipating fin or a heat dissipating protrusion for taking out the light from an LED light source, or a recessed portion formed in each heat dissipating fin or a heat dissipating protrusion to widen the heat dissipating area, .

However, the LED factory and the like have a problem to be solved in addition to the above-mentioned contents.

The first is the brightness of light. LEDs are suitable as indoor lights, but when they are applied to factories, the width / height becomes considerably high. It is becoming a problem for me to come. Also, even though the brightness of the light is good at the time of installation, it may become a little dark because the light decreases over time. In the lighting industry, when the luminous flux drops to 7-80% of the initial luminous flux, the lamp life is considered to have reached the end of its life.

Second, because of the spread of light, factories and the like currently used can emit a large area with only one lamp. On the other hand, the light of the LED has a strong straightness, and the diffusion area is narrow, so the LED module design should be complemented with a polygon from a polygon to a wider diffusion area.

 The third is the Glare phenomenon, and when the light of the lamp enters directly into the human eye, the eyes are instantly blinded. Because the LED is a straight-forward light, it is highly likely that the driver or pedestrian will see the LED light directly. If this happens, you will not be able to see anything for a moment, and there is a risk of an accident. To solve the problem, a diffuser made of opaque acrylic material should be installed, or the reflector should be used to diffuse the light.

Third, since LED generates high heat as a heat emission, if the LED is exposed to heat for a long time, the performance of the LED deteriorates.

The LED lamp disclosed in the Korean Patent No. 10-1286698 has an improved heat dissipation structure. The LED lamp includes a heat sink having an LED module mounted on a bottom surface thereof, a heat transfer body installed on the upper surface of the heat sink to receive heat from the heat sink, And a plurality of heat dissipation fins disposed on the outer circumferential surface of the housing to discharge the heat transferred from the heat conduction body to the outside, wherein the heat conduction body has a hollow structure in which the heat dissipation fins are coupled to the outer circumferential surface, And a core member provided inside the heat radiating pipe and formed of a material having a thermal conductivity lower than that of the heat radiating pipe so that heat transmitted from the heat radiating plate flows to the outside of the heat radiating pipe, The invention differs from the structure of the heat dissipating unit and the method of attaching the holder to the main body.

The angle-adjustable socket protective cap and the LED factory light fixture disclosed therein are disclosed in Japanese Patent Application Laid-Open No. 10-1351981, and have a first protective cap surrounding the top and bottom openings and formed with an open hollow cylindrical pipe shape and surrounding the mother glass and the socket.
