Description

  The present invention relates to an LED lighting device that uses an LED as a light source.

Conventionally, fluorescent light sources that replace conventional white light bulbs have been widely used in consideration of environmental problems, but in recent years, LEDs (light emitting diodes) that are superior to fluorescent light sources in terms of power consumption and light intensity have been used. LED light sources are becoming popular.
An LED light source is configured to realize virtual surface light emission by arranging a plurality of LEDs on a flat surface in an array or a radial shape, to secure a large light emission area and to obtain uniform light (for example, patents). Reference 1, see FIG.
As a specific mode of the LED light source, the fluorescent light source has a shape corresponding to the standard of an existing white light bulb, and the light bulb or fluorescent light so as to correspond to the standard of an existing white light bulb or fluorescent light. Most of the lamps are arranged in a housing that is modeled after the external shape of the lamp.
On the other hand, an LED light source having a unique shape that is different from the standard of the existing light source can achieve high performance without being restricted by the outer shape. As an example, there is known a technique for expanding the irradiation area by diffracting emitted light using an LED and a shielding layer provided on the LED (see, for example, Patent Document 2 and FIG. 3).

The array pattern of the LEDs 133b is an example of the predetermined surface pattern of the present invention, but may be any pattern as long as the LEDs 133b are arranged on the surface, such as a radial pattern.

In the above description, the LED 133b and the power supply device such as a transformer for supplying electric power to the sirocco fans 130a and 130b and other electric circuits are actually provided in the storage container 100. Therefore, illustration and description are omitted.
Further, the arrangement table 134 here is not essential for the present invention, and the light emitting module 130 can be directly mounted on the heat sink 141. The pedestal 133a can play the role of the placement table 134. In this case, the pedestal 133a selects an optimum material in consideration of thermal conductivity.

  In the above configuration, the light emitting module 130 corresponds to the light emitting module of the present invention, the LED light source 133 corresponds to the LED light source of the present invention, the transmission plate 131 corresponds to the lid portion of the present invention, and the housing portion 132 corresponds to the main body. It corresponds to the opening box part of the invention. The arrangement table 134 and the pedestal 133a correspond to the arrangement table of the present invention. Moreover, the part which permeate | transmits the light formed from the opening 132a and the permeation | transmission board 131 corresponds to the permeation | transmission window of this invention. The packing 132d corresponds to the sealing member of the present invention, and the bolt 135a and the nut 135b correspond to the pressing member of the present invention.

The LED lighting apparatus 1 according to Embodiment 1 of the present invention having such a configuration is characterized in that the LED light source 133 is arranged in a sealed state in the light emitting module 130 as shown in FIG. .
That is, as shown in FIGS. 8 and 6, the packing 132 d pressed between the transmission plate 131 and the housing portion 132 is deformed by tightening with the bolt 135 a and the nut 135 b, and is brought into surface contact with the transmission plate 131.

Thereby, the inside of the housing | casing part 132 will be in a sealed state, and the LED light source 133 and the arrangement | positioning stand 134 which are arrange | positioned inside the housing | casing part 132 in the said sealed state will be reliably protected from the inflow of an external water | moisture content or dust. .
Here, when performing maintenance of the LED light source 133, the bolt 135a and the nut 135b are removed to separate the transmission plate 131 and the housing 132, but the packing 132d is made of a flexible material such as rubber or silicon. For this reason, the packing 132d once crushed as shown in FIG. 8B is restored to the original shape shown in FIG. Therefore, the sealing effect of the packing 132d is not lost even if the transmission plate 131 and the casing 132 are repeatedly attached and detached for maintenance.

The LED light source 133 has a characteristic of surface emission by arranging a plurality of LEDs 133b in an array. However, the conventional illumination device focuses on how to protect the LED light source that emits surface light within the illumination device. It was not a thing.

(Embodiment 2)
FIG. 9 is a schematic diagram illustrating a configuration of the LED lighting device according to the second embodiment of the present invention. However, the same code | symbol is attached | subjected to the structure similar to FIGS. 1-8, and the detailed description is abbreviate | omitted.
As shown in FIG. 9, the LED lighting apparatus 2 according to the second embodiment includes a moisture detection sensor 201 provided on a bottom surface portion where the LED light source 133 is disposed in the housing portion 132 of the light emitting module 130, moisture detection. An operation control unit 202 that controls the operation of the LED light source 133 and the notification unit 203 in response to a detection result of the sensor 201, and a notification unit 203 that operates under the control of the operation control unit 202 are provided.

In short, as long as it is an internal space of the light emitting module 130, it can be provided at an arbitrary location.
Further, the notification unit 203 may be realized as a wireless or wired communication interface. In this case, it is possible to notify a remote user having a corresponding communication terminal that the LED lighting device 2 has an abnormality using a network such as a mobile phone network or the Internet. In short, the notification unit of the present invention is not limited by its specific configuration and method as long as it can be notified to the outside.

  Further, in each of the above-described embodiments, the transmission plate 131 is configured to contact the upper edge portion of the housing portion 132. However, as shown in FIG. A step may be provided in the part, and the transmission plate 131 may be realized to fit into the housing part 132. In this case, the sealing effect can be further enhanced.

Further, in each of the above-described embodiments, the light emitting module 130 deforms the packing 132d pressed between the transmission plate 131 and the housing portion 132 mainly by tightening with the bolts 135a and nuts 135b, and the peripheral edge of the open portion.

In this case, when the claw 131b is engaged with the concave portion 132e, a pressure is applied between the transmission plate 131 and the housing portion 132, and the packing 132d is deformed to realize a sealed state. The claw 131b corresponds to another configuration example of the pressing member of the present invention.
The pressing member may be realized by a wood screw or the like. There is an effect that the number of parts can be reduced by omitting the nut 135b.

Further, as long as the packing 132d has flexibility, any natural resin or synthetic resin such as epoxy, polyethylene, etc. can be used as a material in addition to the above-described rubber and silicon.
In short, the lid, the opening box, the sealing member, and the pressing member of the present invention are not limited to specific configurations and shapes as long as the inside of the opening box can be sealed. Absent.
In each of the above embodiments, the transmission plate 131 is described as a transparent flat plate. However, the transmission plate 131 may have a refractive function as a Fresnel lens or a flat lens. Moreover, you may make it diffuse the light inject | emitted by grind | polishing the surface of a permeation | transmission board and processing it into glass shape. In short, as long as it gives at least one optical action of transmission, diffusion or refraction to the light of the LED light source to be transmitted, it is not limited by its shape, material, etc., but any shape, material May be used. This is common to both transmission plates 131 and 122. Further, the transmission plate 122 on the storage container 100 side may be omitted depending on the installation location. Manufacturing cost can be reduced.

Therefore, it is possible to prevent water droplets from staying on the LED light source 133 and reduce the risk of breakage. In particular, when applied to the second embodiment, it also has an effect of increasing the accuracy of moisture detection by the moisture detection sensor 201. In short, the LED light source 133 can be arranged to be inclined at an arbitrary angle as long as the arrangement intersects the vertical direction that is the direction in which the liquid drops fall.

Furthermore, as shown in FIG. 12, the inclination angle of the LED light source 133 may be adjustable.

That is, the inclination of the LED light source 133 can be optimized in consideration of the falling direction of the water drop while adjusting the range of illumination according to the individual use place of the LED lighting device, and on the main surface of the LED light source 133 It is possible to quickly remove the remaining water droplets.
In addition to the hinge 137, a known mechanism such as a rack may be used as a mechanism for changing the inclination angle of the arrangement table 134. In addition, although the range of the inclination angle θ depends on the location of the LED lighting device, the light emission from the LED light source 133 is set to a range of 30 ° to 60 °, more preferably a range of 40 ° to 50 °. Water droplets can be efficiently removed while ensuring efficiency. This angle condition is also applicable when the tilt angle is configured in a fixed manner as shown in FIG.

Although shown as what presses and fixes the part 132, the exterior and opening box part of this invention are not limited by the external shape and the internal shape of an opening box part. In addition, the configuration example shown in FIG. 11 includes a pair of LED light sources 133 that are inclined with respect to the bottom surface 132c of the housing part 132. However, in the present invention, the LED light source 133 disposed in the open box part is provided. It is not limited by the number.
