Description

Technical Field [0001] The present invention relates to an LED lighting module and an LED lighting device using the LED lighting module.

The present invention relates to a heat exchanger for connecting a long heat radiating fin extending over a long axis of a long hole formed in a base plate and a short heat radiating fin extending along a short axis of the long hole to a large number of radiating fins to maximize heat dissipation while minimizing noise, And more particularly, to an LED lighting module and an LED lighting device using the LED lighting module, which further form a heat dissipation space in which the fastening brackets contact each other when arranged in parallel.

As a conventional LED light module, for example, a technology disclosed in a patent document (Korean Patent No. 10-1406515) has been proposed.

11 to 13, a conventional LED lighting module 1000 is provided with a heat dissipation passage 1022 at the center, and a plurality of heat dissipation vanes 1024 radially formed on the outer circumferential surface of the heat dissipation passage 1022 An LED substrate 1040 that is seated and fixed to a lower portion of the module body 1020 and a module body 1020 that is fixed so as to seal the LED substrate 1040 and the module body 1020, And a lower case 1060 having a radiator hole 1062 corresponding to the radiator 1022.

The module main body 1020 has a rectangular shape as a whole and is provided with a heat dissipating passage 1022 having a long hole protruding upward from the center thereof and a plurality of heat dissipating vanes 1024 radially outside the outer circumferential surface of the heat dissipating passage 1022, And a seating surface 1028 on which the power supply connecting means 1026 is provided and on which the LED substrate 1040 is mounted is opened downward and both sides.

In addition, the module body 1020 is preferably made of an aluminum material having a high thermal conductivity, but may be formed of various materials having excellent thermal conductivity according to the user's selection. For example, it may be made of the same material as brass, the lower part may be made of brass, and the upper part may be mixed with aluminum material.

It is preferable that a connection hole 1029 for connecting the power line inserted by the power connection unit 1026 provided in the module main body 1020 to the LED substrate 1040 is provided.

However, the conventional LED light module has the following problems.

Since the heat dissipation passage 1022 is a chimney protruding from the lower surface to the upper side, air flow generated in accordance with the flow of the vehicle when using the heat dissipation passage 1022 as a patent tunnel lamp is caused to generate noise in the heat dissipation passage 1022.

This noise can be uncomfortable to the driver because it comes from an enormous number of tunnel luminaires.

Since the heat dissipating passage 1022 is in the form of a chimney, more material is required.

Further, the heat dissipation passage 1022 merely functions as a passage through which the air flows from bottom to top, and does not take a direct cooling form of the plurality of heat dissipating vanes 1024.

Further, since the power supply line is pulled out from the connection hole 1029 when the power supply line is drawn out, the layout is limited when the power supply line is long depending on the shape of the luminaire.

Further, since the entire module body 1020 is injection-molded with a metal such as aluminum, it is heavy and expensive. (Although it is not a single one, the number of lamps depends on the installation of lighting,

Meanwhile, when the LED lighting module 1000 is installed in series with the lower case as shown in FIG. 13, the air is adhered to each other side by side so that air flows only to the heat radiation path 1022, which limits the cooling performance.
