BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent by reference to the embodiments described in detail below with reference to the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, a sensing module according to a preferred embodiment of the present invention and an LED lighting using the same will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a sensing module according to an embodiment of the present invention.

Referring to FIG. 1, a sensing module 100 according to the present invention includes a clock controller 110, a clock generator 120, a motion sensor 130, and an output controller 140.

A clock controller (110) receives power from an external power source module (200) and supplies power to a predetermined clock.

The clock generator 120 receives power from the clock controller 110 and generates a clock signal for supplying power for a predetermined time in response to the motion signal. The clock signal may be a signal that specifies the power and duration of the power supplied from the output controller 140, which will be described later. For example, when a motion signal is input to the clock generator 120 by the motion sensor 130, the clock generator 120 may cause the output controller 140 to output a 40W power for one minute to the LED lighting module 300 And generate a signal that allows dimming to be performed while reducing power supplied to the LED lighting module 300 by 4W or 0W for 30 seconds thereafter.

A motion sensor 130 senses an external motion to generate a motion signal. The motion sensor may be an infrared sensor or the like.

The output controller 140 receives power from the clock generator 120 and generates a clock signal having a predetermined power for a predetermined time (for example, 40W 1 minute, 32W 10 Sec, 24W 10 sec, 12W 10 sec, 4W sustain) power to the LED lighting module 300.

At this time, the clock controller 110 can receive the AC power from the power source module 200. In this case, the clock controller 110 may include a waveform adjusting circuit (not shown) for adjusting the waveform of the AC power supply.

Also, the clock controller 110 may receive DC power from the power source module 200.

In addition, the clock controller 110 may include an overvoltage protection circuit (not shown) to protect the sensing module 100 or the LED lighting module 300 when an unexpected overvoltage is applied from the outside.

FIG. 2 shows an LED lighting lamp according to an embodiment of the present invention, and more specifically, a fluorescent lamp type LED lighting lamp.

Referring to FIG. 2, the LED lighting lamp according to the present invention includes a case 210, an LED lighting module (300 in FIG. 1), cap portions 220a and 220b, and a sensing module (100 in FIG.

The case 210 forms the appearance of the lighting apparatus, and an LED lighting module is mounted inside. When the case is formed in a tubular shape such as a general household fluorescent lamp, the LED lighting lamp according to the present invention can be a fluorescent lamp type LED lighting lamp.

The case 210 may include an upper case 210a (FIG. 5) and a lower case 210b (FIG. 5). In the case of the upper case 210a, a reflective surface corresponding to the body is formed, and the LED lighting module mounting portion is formed. When the upper case 210a is formed of metal such as aluminum or stainless steel, it is easy to dissipate heat, and the reflection surface itself is formed, which is more advantageous.

The lower case 210b protects the LED lighting module 300 and diffuses light generated from the LED lighting module 200 to the outside. To this end, the lower case 210b may be formed of a translucent polymer material such as a polycarbonate coated with a milky white coating or the like.

The LED lighting module 300 is disposed in the case 210, and is powered by an output controller (140 in FIG. 1).

The cap portions 220a and 220b are coupled to a side surface or a rear surface of the case 210 and are electrically connected to an external power source module 200 of FIG. When the case 210 is a tubular case, the cap portions 220a and 220b can be coupled to the side of the tubular case. In this case, the cap portions 220a and 220b are fixed to a ceiling structure, And a protruding power connection unit 240 that can be electrically connected to the outside.

In the present invention, the sensing module 100 is coupled to the cap portion 220b.

FIG. 3 shows an example in which the sensing module is coupled to the cap portion in FIG.

Referring to FIG. 3, the sensing module includes a substrate 230 on which a clock controller, a clock generator, a motion sensor 130, and an output controller as described above are also coupled. A coupling part 235 is formed on the substrate 230 so that the sensing module can be coupled to the cap part 220b by screwing or the like.

When the case 210 is a tubular case, the motion sensor 130 is vertically coupled to the surface of the substrate 230 so that the motion sensor 130 is moved downward in a state where the sensing module is coupled to the cap portion 220b. Is more preferable. In general, when a motion sensor is mounted on a LED lighting lamp, it is directly coupled to the substrate. When such a structure is applied to a fluorescent LED lighting, the sensing range of the motion sensor is limited to the side. However, in the case of the present invention, the motion sensor 130 is vertically coupled to the substrate surface as in the example shown in Fig. 3, so that in the fluorescent lamp type LED lamp, as shown in Figs. 4 and 5, So that the sensing range can be maximized.

Fig. 4 shows an example of the cap part in Fig. 2, and Fig. 5 shows another example of the cap part in Fig.

The example shown in FIG. 4 corresponds to an example in which the protective cap 250 is formed so as to protect the motion sensor protruding from a shape in which the motion sensor protrudes downward. On the other hand, the example shown in Fig. 5 corresponds to an example in which a separate protective cap is not formed in a state in which the motion sensor is not protruded.

As described above, the LED lighting lamp according to the present invention includes a sensing module capable of performing various functions such as a motion sensing function and a dimming function, thereby being usefully used in a parking lot, a park, a tunnel, etc. where motion sensing and dimming functions are required .

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. These changes and modifications may be made without departing from the scope of the present invention. Accordingly, the scope of the present invention should be determined by the following claims.
