Description
The present invention relates to a studio strobe, and more particularly, to an LED module employing an air cooling method and a studio strobe and an LED lighting device using the module to make luminescent characteristics close to natural light.
Strobe is a device that illuminates a scene by generating a flash of instantaneous light, and refers to a device that illuminates a subject or its surroundings when shooting a camera. Generally, it is used to illuminate a scene momentarily at low light intensity, but it is usually used to brighten relative dark areas within a certain distance. The strobes have a short duration of light emission and the color temperature is close to 5500K, which is the sunlight color temperature during the daytime, and the light quantity and the light quality are uniform and can be repeatedly used.
Strobes are mainly built-in strobe built in a small digital camera, and have a mounting base for pushing and fixing the camera on a hot-shoe on the camera, which is also called a hot-shoe strobe A clip-on type strobe, a handel-mounted strobe with a handle with a built-in battery pack, and a studio sticker that is connected to a separate power pack or power source.
The principle of the strobe is to charge the current to a capacitor and momentarily discharge it to flow a large current to produce light requiring high output. In the past, Xenon lamps were used mainly as a light source, in which a pair of electrodes was placed in a quartz tube sealed with Xenon gas to generate a discharge to emit light. The Xenon lamp produces light close to natural light but has a poor light efficiency in which the energy consumed is converted into light and is difficult to illuminate the area to be illuminated uniformly due to the characteristic of the lamp type point light source, Because of the large power, it takes a lot of charging time. Above all, there is a problem that ultraviolet rays and infrared rays are emitted to the human body and are not free from the controversy of harmfulness.
In order to solve such a problem, a studio strobe using an LED module as a lamp has been proposed. However, heat generation of the LED light source is a problem. Korean Patent No. 10-1178430 discloses a technology relating to a heat radiator for radiating divergent heat of an LED module in a 'camera strobe device'.
