- the mounting substrate 400 is formed so that an outside air intake space S is formed between the inner peripheral walls 600 d of the pair of side surfaces 607 and 608 of the housing 600.
- screws 605 and 606 for fixing a U-shaped handle 604 are used in the vicinity of the opening ends 600 b of the pair of side surfaces 602 and 603 of the housing 600 so as to be fixed to the pair of side surfaces 602 and 603.
- Mounting seats 400c and 400d are formed.
- the mounting base 400 can be incorporated into the housing 600 by fitting the mounting seats 400 c and 400 d into the opening end 600 b serving as the opening surface of the housing 600 and screwing the mounting seats 400 c and 400 d to the pair of side surfaces 602 and 603 with screws 605 and 606.
- the protective cover 300 is formed so as to cover the plurality of projectors 200 along the outer periphery of the mounting substrate 400, and the outer portion is formed to be low in steps.
- the part 301 is fixed to one plate surface 400a by screwing or the like.
- the protective cover 300 is formed of a transparent synthetic resin such as polycarbonate or acrylic resin. Further, the step portion 301 of the protective cover 300 is covered with an edge cover 302 fixed to the mounting substrate 400.
- the plurality of plate-like cooling fins 500 are formed so as to protrude from the outside air intake space S and be cooled by the outside air entering from the outside air intake space S, as shown in FIGS.
- the plate-like cooling fins 500 are formed in a rectangular shape, and are fixed to the mounting substrate 400 so that the longitudinal direction is along the pair of side surfaces 602 and 603 of the housing 600 when the mounting substrate 400 is assembled into the housing 600. Yes.
- the plurality of plate-like cooling fins 5 are arranged in parallel at equal intervals along the pair of side surfaces 607 and 608 of the housing 600.
- the space between the plate-like cooling fins 500 is formed in a space in the housing 600 where a venturi effect occurs.
- interval between the plate-shaped cooling fins 500 the flow velocity of the external air passing between the plate-shaped cooling fins 500 can be increased.
- each plate-shaped cooling fin 500 are formed along a pair of side surfaces 607 and 608 of the housing 600, and the occupied area in the outside air intake space S of the plurality of plate-shaped cooling fins is an animal such as a bird.
- the size is such that it cannot enter the housing recess 600a of the housing 600 from the opening surface. Since the conventional illumination lamp has a sealed structure, animals such as birds do not enter, but in the illumination lamp 100 of the present invention, an outside air intake space S is formed between the mounting substrate 400 and the inner peripheral wall 600d of the housing 600.
- Such a plate-like cooling fin 500 is preferably made of the same heat conductive material as that of the mounting substrate 400. Since the heat conductivity becomes the same by making the mounting substrate 400 and the plate-like cooling fins 500 the same heat conductive material, the heat transfer efficiency is improved.
- the mounting substrate 400 and the plate-like cooling fin 500 are made of a metal having a high thermal conductivity such as a magnesium alloy, an aluminum alloy, or copper. Since the illuminating lamp 100 is lighter and easier to install, a magnesium alloy is preferable.
- the mounting substrate 400 to which the plurality of light projectors 200, the protective cover 300, and the plurality of plate-like cooling fins 500 are attached is disposed in a half space on the opening end 600b side of the housing 600, and in the remaining space of the housing 600.
- a power supply box 601 is arranged at a half position on the upper wall 600c side.
- the thermal energy generated by the light emission of the plurality of LEDs is generated. The operation for spreading outside will be described.
- the heat generated by each LED is transmitted to the plurality of plate-like cooling fins 500 via the mounting substrate 400, and thus from the plurality of plate-like cooling fins 500.
- a heat rising air flow is generated by the dissipated heat, and the outside air is sucked from the outside air intake space S. Since the sucked outside air passes through a narrow space between the plurality of plate-like cooling fins 500, the flow rate of the heat rising air flow increases due to the venturi effect, and a larger amount of air than the normal atmospheric state is cooled by the plurality of plate-like cooling. It passes between the fins 500.
- the outside air that has entered from the outside air intake space S heated by the heat radiation action of the plurality of plate-like cooling fins 500 has, for example, a plurality of slits 609 perforated on the side surface 607 positioned above the plurality of plate-like cooling fins 500. In this case, a large amount of air is released to the outside from the plurality of slits 609 by the heat rising airflow.
- the outside air can be efficiently taken into the lamp space, and the outside air can be directly guided to the plate-like cooling fin 500 and further escaped to the slit 609, so that the cooling efficiency can be greatly increased. Therefore, it is suitable for high power LEDs that generate a large amount of heat.
- the illumination lamp of the present invention can be used as illumination for parking lots, street lamps, halls, train operation areas, building lighting, and the like.
