Abstract

The present invention provides an LED lighting unit that is lightweight and can be installed by connecting a plurality of units to a warehouse, a factory, a gymnasium, or the like. An LED light source and a mounting fixture are integrated to provide a rail-type heat radiation band with claws on both sides of an LED lighting unit having a built-in power supply so that a plurality of the same type of LED lighting units can be connected. . This LED lighting unit can be used alone, but the necessary brightness performance can be obtained by connecting a plurality of one model with two, three, and four units. Moreover, since it is very lightweight even when compared with the conventional expensive and heavy LED lighting fixtures, it solves the problem of installation compatibility. [Selection] Figure 1

Description

  The present invention relates to an LED lighting unit characterized in that a heat sink band having a connecting function is provided on both side surfaces of an LED lighting unit in which an LED light source and a power source are integrated, and the same type LED lighting unit can be connected.

In recent years, the removal of incandescent light bulbs with high power consumption has been promoted around the world from the viewpoint of protecting the global environment.
In Japan, LED lighting that has a longer lifespan than incandescent bulbs and excellent power saving performance has attracted attention, and many LED lighting fixtures have been developed.
Currently, the life of LED lighting is about 40 times longer than incandescent bulbs, so maintenance such as running out of bulbs is drastically reduced. This will greatly reduce the maintenance cost.
However, when the brightness performance equivalent to that of the existing lighting fixture is required, there is a problem in the installation compatibility in consideration of the price and the installation cost.
As a major factor, the heat generated by the LEDs greatly affects the performance and life of the LED lighting, so that heat radiation of the LED lighting fixture body is an important issue.
For this reason, the heat radiation portion is large in proportion to the brightness performance, and the built-in power source is also heavy, and as a result, the LED illumination main body is heavy and heavy.
For this reason, when installing in place of the light mercury lamps used in high ceiling warehouses, factories, gymnasiums, etc., it was necessary to perform rugged installation work.
Conventional lighting such as LED lighting, incandescent bulbs, fluorescent lamps, mercury lamps, etc. are individually commercialized depending on their brightness performance, and therefore, special instruments having sockets suitable for the luminous bodies are required.

  As described in [0002], conventional LED lighting fixtures have a problem in installation suitability in consideration of the price and installation cost when brightness performance equivalent to that of existing lighting fixtures is obtained.

  In order to solve these problems, instead of using individual LED lighting fixtures according to brightness performance as in the past, LED light sources and mounting fixtures are integrated into a LED lighting unit with a built-in power supply, and both sides of the body By providing a plurality of the same type of LED lighting units, the brightness performance required is secured by providing a rail-type heat sink band having claws, and the problem is solved as a lightweight and inexpensive LED lighting unit.

It is a perspective view of the LED illumination unit 2 group connection example. It is a front view of 2 LED illumination unit connection part. It is an enlarged front view of 2 LED illumination unit connection part. It is a perspective view of the LED lighting unit 3 group connection example.

  The embodiment will be described below with reference to FIG. 1a is an LED lighting unit body, and the body is made of magnesium or aluminum alloy, which has a high heat dissipation effect and is light. The front and back surfaces are provided with a fixing bracket mounting portion 13 and a screw hole 14 that are fixed when a plurality of LED lighting units are connected. In addition, rail-type heatsink strips 3 and 4 having a plurality of claws are provided on both side surfaces, and a heatsink strip 5, a power cord 10, a plug-in type cable connector 8 for supplying electricity to connected devices, and ceiling mounting In order to allow the mounting bracket 11 joined with the bolt 12 to be mounted at an arbitrary location, rails 7 are also provided on the rail 6 and the side surface so as to be slidable.

  As shown in the AA sectional view of FIG. 2, an LED light source unit 17 is provided inside the main body 1a, and a cover 2 for diffusing light and preventing dust is provided.

FIG. 3 shows an example of a process for joining a 1b body of the same type as the 1a body.
The rail 4 having the claw provided on the left side surface of 1b is aligned with the rail 4 having the claw provided on the right side surface of the main body 1a, and is slid from either the front or back to be connected.

4, the connecting fixture 15 is set on the fixture mounting portion 13 provided before and after connecting the LED lighting unit body 1 a to the LED lighting unit main body 1 a and fixed with screws 16.
The wiring cord 18 is used for wiring to the plug-in type power cable connector 1b connected from the plug-in type power cable connector 8 of 1a.
A mounting bracket 11 in which a ceiling mounting bolt 12 is joined to the rails 6 and 1b of the connected LED lighting unit main body 1a is attached to a structure such as a ceiling or a wall surface.

  FIG. 5 is a front view showing a joint portion of the LED lighting unit main body 1b connected to the LED lighting unit main body 1a.

  FIG. 6 is an enlarged view of the joint shown in FIG. As shown in the figure, there is a space at the joint between 1a and 1b, and the heat dissipation effect is not impaired.

  By connecting a plurality of LED lighting units of the present plan, the brightness performance can be easily changed without using a dedicated lighting fixture as in the prior art. In addition, since it is lightweight, it can be installed without problems even if it is installed in place of the light mercury lamp used in warehouses, factories, and gymnasiums with high ceilings.
