Abstract

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.

Claims (24)

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; and

the number of LEDs mounted on the mounting surface of the LED substrate is 4 to 25 per 120 mm 2 .

2. The LED module for flashing lamp according to claim 1 , wherein a distance between the adjacent LEDs is 0.2 to 0.5 mm.

3. The module for flashing lamp according to claim 1 , wherein the LED has a width of 1.8 to 5.3 mm.

4. The LED module for flashing lamp according to claim 1 , wherein an effective luminous intensity is 6,000 to 20,000 cd per flashing time of 1 to 5 msec.

5. The LED module for flashing lamp according to claim 1 , wherein a brightness is 300,000 to 1,600,000 lumen (lm).

6. The LED module for flashing lamp according to claim 1 , wherein the resin layer is a phosphor resin layer.

7. 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.

8. The flashing lamp according to claim 7 , wherein the flashing lamp is for flashing for the landing guidance of an aircraft.
