LED module for flashing lamp and flashing lamp
The present invention provides an LED module that can prevent breakage of an LED chip due to pulse lighting for a flash when the LED module is used in a flashing lamp. An LED module ( 10 ) for flashing lamp includes: an LED substrate ( 13 ); plural LEDs ( 12 ); and plural resin layers ( 11 ). In the LED module ( 10 ), the LEDs ( 12 ) are mounted on a mounting surface of the LED substrate ( 13 ). Each resin layer ( 11 ) is stacked on a surface of each LED ( 12 ) opposite to the LED substrate ( 13 ). Adjacent resin layers ( 11 ) stacked on the LEDs ( 12 ) are separated from each other.
1. An LED module for a flashing lamp comprising:
an LED substrate;
plural LEDs; and
plural resin layers, wherein
the LEDs are mounted on a mounting surface of the LED substrate,
each resin layer is stacked on a surface of each LED opposite to the LED substrate,
adjacent resin layers stacked on the LEDs are separated from each other,
adjacent LEDs are separated from each other, the width between the adjacent LEDs is 0.2 to 0.5 mm; and
the total number of LEDs mounted on the LED substrate is 200 to 2,000.
2. The module for flashing lamp according to claim 1 , wherein the shape of the LEDs is a square shape or a rectangular shape, and the LED has a width of 1.8 to 5.3 mm.
3. The LED module for flashing lamp according to claim 1 , wherein a thickness of the resin layer is 100 to 300 μm.
4. A flashing lamp comprising:
an LED module serving as a light source;
a light distribution unit;
a housing having an opening; and
a light transmissive cover, wherein
the LED module is the module for flashing lamp according to claim 1 ,
the LED module and the light distribution unit are disposed inside the housing,
the light distribution unit is disposed on a light emission side of the LED module, and
the light transmissive cover is disposed over the opening of the housing.
5. The flashing lamp according to claim 4 , wherein the flashing lamp includes an arm, a leg, and a cable for supplying power to the LED module for flashing for the landing guidance of an aircraft.
6. The flashing lamp according to claim 4 , wherein the flashing lamp is configured to achieve flashing 120 times per minute.
7. The flashing lamp according to claim 4 , wherein the flashing lamp is used among three levels of brightness.
8. The flashing lamp according to claim 4 , wherein the flashing lamp is for flashing for the landing guidance of an aircraft.
