The difference between led fill light lamp and flash lamp is analyzed in detail.
I. Introduction of led fill light and flash lamp
1.Brief Introduction of LED Fill Light
LED fill light lamp is a solid-state light-emitting device, also known as light-emitting diode, which drives semiconductor devices to emit light with small current, with low power consumption and high stability, but relatively weak brightness. Less fever, good heat dissipation. You can get close to plants without making them anxious. Based on this characteristic, LED can be placed horizontally or vertically above plants, so it can greatly reduce the loss of light and provide light effect.
2. Introduction to 2.Flash
Flash: it can emit strong light in a short time and is a photographic accessory for photographic sensitivity. Mostly used in dim light? Intermittent lighting is also used to fill the local light of the main body in bright light. Compact appearance, safe use, convenient carrying and stable performance.
Second, the principle difference between led fill light lamp and flash lamp
1.Principle of LED fill light
Fill light lamp is a kind of lamp generally used to improve the lack of light on the front of an object. LED fill light? A way to make up for it. This kind of fill light lamp is generally made of high brightness light emitting diode (LED). The so-called fill light lamp is a kind of special lighting equipment that projects specific light onto the illuminated object and directly or indirectly obtains light for fill light.
2. Flash principle
When the flash is fully charged, the synchronous contact of the flash on the camera is connected to the flash circuit. During the flash, the light emitted from the flash illuminates the subject, reflects from the subject and enters the camera (for exposure) and the flash metering element. The photometric element quickly converts the light energy into an electrical signal and inputs it into the integration circuit, and then the integration circuit outputs an electrical signal proportional to the light value of the flash lamp; When does the value of the flash reach the importance of proper exposure? Canon external flash? When looking for time, the output electric signal of the integration circuit will make the control circuit trigger the flash stop circuit, thus making the flash go out.
Third, the difference between led fill light and flash light
Flash is a kind of fill light. Flash is a photographic accessory that can emit strong light in a short time. Mostly used in dim light? Intermittent lighting is also used to fill the local light of the main body in bright light. Compact appearance, safe use, convenient carrying and stable performance. Fill light lamp is a kind of lamp used to compensate some equipment or plants for lack of light. At present, there are usually three kinds of fill light, one is camera greenhouse fill light (also called plant fill light), photography fill light (also called camera fill light) and license plate fill light (also called white light).
After reading this article, you must be able to distinguish between led fill light and flash light. Generally speaking, flash is a kind of fill light, both of which can be used for lighting in dim environment, but the difference is that flash is a professional tool to fill light when shooting outdoors. Therefore, it is often used when shooting outdoors, and fill light is also used when shooting, but it is relatively unrestricted. To sum up, led fill lights and flashlights are widely used in daily life.
