Description

  The present invention relates to a lighting apparatus and an aquarium for breeding and watching ornamental fish, corals, aquatic plants, and the like.

  2. Description of the Related Art In recent years, lighting fixtures of various structures have been provided for indoor aquatic organisms such as ornamental fish, corals, and aquatic plants in the aquarium. In particular, metal halide lighting equipment that emits high-intensity light is frequently used for breeding reef-forming sea corals and giant clam shellfish.

  However, since the lamp has a wide spectral distribution from ultraviolet rays to infrared rays, it has disadvantages such as darkening of the body color of ornamental fish due to ultraviolet rays and an undesirable increase in water temperature inside the aquarium due to infrared rays.

  In order to overcome the above drawbacks, LED lighting fixtures such as utility model registration No. 3094744 have been devised. However, since a cooling device such as a heat sink or a cooling fan is not provided, the temperature of the LED substrate rises, and the life of the LED is shortened and the brightness is reduced. Furthermore, in order to suppress the temperature rise of the substrate, the number of LEDs per unit area on the substrate and the LED current are limited, so that the brightness of the LED lighting fixture cannot be increased as much as the metal halide lighting fixture. There are drawbacks.

Effect of device

  According to the ornamental lighting fixture of the present invention configured as described above, the substrate to which the LED is soldered is fixed to the heat sink, and the heat sink is forcibly cooled by the cooling fan, so that the temperature rise of the LED is suppressed. It is possible to realize high brightness and long life of the LED.

  Further, by providing a power control timer in the AC power source or the lighting fixture, the lighting fixture can be automatically turned on / off at an arbitrary time. In addition, the luminance can be manually adjusted by providing the luminance control circuit in the AC power source or the lighting fixture.

Each of the aquarium fish tanks with the ornamental lighting fixtures is shown.

  As shown in FIG. 1, an ornamental lighting fixture 1 according to the present invention includes a housing 2 made of a thin metal plate such as aluminum, has a power switch 3, and a plurality of exhaust ports 4 and exhaust ports 5 have upper and side surfaces. It is in. Moreover, the hanging fixture 6 for hanging the ornamental lighting fixture 1 is provided with one or more.

  As shown in FIG. 2, an optical lens 7 is bonded to the LED 8 inside the ornamental lighting device 1, and the LED 8 is soldered to the substrate 9. The plurality of substrates 9 are fixed to a heat sink 14 such as aluminum, and the heat sink 14 is forcibly cooled by a cooling fan 13. The drive circuit 12 connected to the substrate 9 distributes the power supplied from the outside to the LEDs 8.

  The light emitted from the LED 8 is emitted to the outside through the transparent plate 10 having a high transmittance such as glass or acrylic resin. The wavelength of the LED 8 may be any wavelength as long as it emits visible light that satisfies the growth conditions such as corals and aquatic plants without sacrificing beauty in order to appreciate the living body.

  The heat sink 14 is fixed to the casing 2 of the ornamental lighting fixture 1 with a metal fitting 11. By preventing the temperature inside the ornamental lighting fixture 1 from being increased by the heat sink 14 and the cooling fan 13, the LED 8 can be driven with a large current to increase the luminance. In addition, the life of the LED 8 is extended. The transparent plate 10 serves to prevent water droplets from entering the ornamental lighting apparatus 1. The LED 8 may be an organic EL.

  As shown in FIG. 3, there are a plurality of holes 15 for emitting light on the bottom surface of the ornamental lighting fixture 1.

  The power supply to the ornamental lighting device 1 is performed by the DC cord 16 as shown in FIG. It is possible to adjust the luminance of the ornamental lighting device 1 for each hour by inserting a controller 17 including a power control timer 18 and a luminance control circuit 19 in the middle of the DC cord 16. The DC cord 16 is connected to an AC adapter 20, and power is supplied to the AC adapter 20 through an AC cord 21 and an outlet 22.

  In the circuit diagram 23 shown in FIG. 5, the power switch 3, the fuse 24, the temperature fuse 25, and the polyswitch 26 are connected in series to the DC power supply terminal 30, and between the terminal between the temperature fuse 25 and the polyswitch 26 and the ground terminal 31. The cooling fan 13 is connected. Further, a plurality of LED circuits 28 in which a plurality of LEDs 8, a single resistor 27, and a fuse 24 are connected in series are connected in parallel between the poly switch 26 and the ground terminal 31. The fuse 24 and the temperature fuse 25 protect the ornamental lighting device 1 from overcurrent and temperature abnormality, respectively, and the polyswitch 26 detects the current of the LED circuit 28 when the internal temperature of the ornamental lighting device 1 rises (decreases). The resistor 27 decreases (increases) the current of the LED circuit 28 when the current of the LED 8 increases (decreases). The poly switch 26 and the resistor 27 form a feedback circuit for making the current flowing through the LED 8 constant even if the DC power supply voltage and the internal temperature of the ornamental lighting fixture 1 fluctuate.

  According to this drive circuit 12, since a capacitor that causes a failure of many electric devices is generally unnecessary, the life of the ornamental lighting apparatus 1 can be extended.

  FIG. 6 shows an aquarium fish tank 32 according to the present invention. The water tank 33 is composed of a transparent member made of glass, acrylic resin, or the like, and is formed in a shape opened upward. An illumination stand 34 is placed on the upper frame of the water tank 33, and the ornamental lighting device 1 is suspended at an appropriate height by the hanging tool 6. By having the LED 8 that hardly emits infrared rays as a light source, it is possible to prevent an increase in the internal temperature of the water tank 33 and to reduce power consumption for raising a living body.
