Abstract

PROBLEM TO BE SOLVED: To provide a power supply module for LED lighting apparatuses suitable for arrangement, as well as an LED lighting unit, an LED lighting apparatus, and an LED illumination system using the same.SOLUTION: Power supply modules (Z1-1 to i, Z2-1 to j, and Zm-1 to k) each include a first contact Z11 which is supplied with AC power from outside the module, a second contact Z12 which is used to convey the AC power supplied to the first contact Z11 to outside the module directly as is, and a power supply circuit Z13 which converts the AC power supplied to the first contact Z11 into DC power before being supplied to an LED module (not shown).

Description

  The present invention relates to a power supply module, an LED lighting unit, an LED lighting device, and an LED lighting system.

  FIG. 28 shows a cross-sectional view of an example of a conventional LED illumination device (see, for example, Patent Document 1). The LED illumination device 90 shown in the figure includes a long rectangular substrate 91, a plurality of LED chips 92 mounted on the substrate 91, a tube 93 that accommodates the substrate 91, a terminal 94, and the LED chip 92. And a circuit 95 for lighting. On the substrate 91, wirings (not shown) connected to the plurality of LED chips 92 and the terminals 94 are formed. The LED lighting device 90 is configured to allow the plurality of LED chips 92 to emit light by fitting the terminal 94 into a socket of a general fluorescent lamp lighting fixture. Since the LED chip 92 has low power consumption and long life, if the LED lighting device 90 is used as an alternative to a fluorescent lamp, improvements in cost and environment can be expected. The general-use fluorescent lamp luminaire is a luminaire widely used mainly for indoor general illumination. For example, in Japan, a commercial 100 V power source is used, and a straight-tube fluorescent lamp defined in JIS C7617 or A lighting fixture to which a ring-shaped fluorescent lamp defined in JIS C7618 is attached.

  However, the lighting fixture using the conventional fluorescent lamp is configured on the premise that the terminals 94 exist at both ends thereof and emit light in the entire circumferential direction. For this reason, for example, when a plurality of LED lighting devices 90 are attached to a lighting fixture in which a plurality of fluorescent lamps are arranged in series, a dark portion that does not emit light is generated between the adjacent LED lighting devices 90. Those who see it may feel it is not good looking. Or even if it is a case where it is a case where it is intended to illuminate a part of wall surface, if LED lighting apparatus 90 is used, light will be irradiated besides the location which wants to shine. For this reason, for example, it is compelled to provide a light shielding cover that covers a half circumference of the LED lighting device 90. Moreover, in the conventional LED lighting device 90, the correspondence to a phase control type dimmer (such as a triac dimmer) has not been considered.

By using the inner groove 412, the LED lighting unit 101 can be easily and reliably attached, and a decorative plate for hiding the inside of the LED lighting unit 101 can be provided at a desired position.

  By providing the cover 500 with the emission side surface 510 that is flush with the outer side surface 411 and by making the emission top surface 520 flat, the appearance of the LED illumination unit 101 can be made smart.

  By providing the locking piece 710 and the pair of fitting pieces 720 on the cap 700, the cap 700 can be securely attached to the heat radiating member 400 by so-called one-touch.

  As shown in FIG. 16, in the LED lighting system 121, the light from the plurality of LED lighting units 101 has a wall surface 802 because the emission top surface 520 is planar and the cover 500 diffuses the light. And the floor surface 803 is widely irradiated. This is suitable for more uniformly and widely illuminating the entire room where the LED lighting system 121 is installed.

  17 to 27 show another embodiment of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.

The eaves part 805 extends in the y direction from the edge of the ceiling surface 801 in the y direction, and covers the right side portion of the installation groove 804 in the entire length of the installation groove 804. The plurality of LED lighting units 102 are arranged in series in the x direction with the lens unit 530 facing downward in the z direction (the direction of the floor surface 803).

  Even in such an embodiment, when the LED module 102, the LED lighting device 112, and the LED lighting system 122 are turned on, most of the light emitting portions extending linearly occupy a good appearance.

  By providing the lens unit 530, the light from the plurality of LED modules 300 is collected in the y direction. This light collection is softened according to the degree to which the cover 500 diffuses light. Thereby, as shown in FIG. 25, the LED illumination system 122 functions as indirect illumination in which the upper side portion (hatched portion in the drawing) of the wall surface 802 is brightly illuminated. The eaves portion 805 can avoid the light from the LED lighting unit 102 reaching the floor surface 803 or the like directly.

<Third Embodiment>
FIG. 26 shows an LED lighting unit according to a third embodiment of the present invention. The LED lighting unit 103 of the present embodiment is different from the above-described embodiment in the configuration of the cover 500.

The LED illumination system 123 of this embodiment includes a plurality of LED illumination units 103, and further includes a ceiling surface 801, a wall surface 802, an installation groove 804, and an eaves portion 805 as its components. The installation groove 804 is located between the edge in the y direction of the ceiling surface 801 and the wall surface 802, and is a groove having a rectangular cross section extending long in the x direction. The eaves part 805 extends in the y direction from the edge of the ceiling surface 801 in the y direction, and covers the right side portion of the installation groove 804 in the entire length of the installation groove 804. The plurality of LED lighting units 102 are arranged in series in the x direction with the lens unit 530 facing downward in the z direction (the direction of the floor surface 803).

  Even in such an embodiment, when the LED module 103 and the LED lighting system 123 are turned on, the light emitting portion extending linearly occupies most of it, and the appearance is good.

  By forming the lens portion 530 from a transparent material, it is possible to sufficiently collect light from the plurality of LED modules 300 in the y direction. Thereby, as shown in FIG. 27, in the LED illumination system 123, a region (hatched portion in the drawing) from the upper side portion of the wall surface 802 to the lower side portion is illuminated brightly. Therefore, the LED illumination system 123 functions as indirect illumination in which the entire wall surface 802 shines brightly.

By setting it as such a structure, it becomes possible to handle i LED lighting units Y1-1 to Yi seamlessly as if it were the single LED lighting apparatus X1. Moreover, it becomes possible to arbitrarily adjust the longitudinal direction size of the LED lighting device X1 by changing the number i of the LED lighting units Y1-1 to Yi in series.

  The same applies to the LED illumination devices X2 to Xm.
