Led fill light is a kind of solid-state light-emitting device, also known as light-emitting diode. It is driven by a small current to light semiconductor devices, with small power consumption and high stability, but the brightness is relatively weak. Less heat, good heat dissipation. It can be close to plants without burning them. Based on the characteristics of LED fill light, LED can be placed horizontally or vertically on the top of plants, so it can greatly reduce the loss of illumination and provide light effect.
Fill light can be divided into light control, non light control (always on) 2 kinds.
Light control is to add light control silicon controller, non light control is always on, dark out through power control.
1. Led meaning
LED is the abbreviation of light emitting diode. Its basic structure is an electroluminescent semiconductor material, which is placed on a shelf with lead wire, and then sealed with epoxy resin around to protect the internal core wire. But the brightness is relatively weak.
Because of low energy consumption and high brightness, LED lights are generally used in camera phones to supplement the light when it is not.
Now some mobile phones have used the same flash as the camera, such as Sony Ericsson K790C, which uses xenon flash. The effect is much better than the LED fill light, but it can not be used as a flashlight as the LED is always on.
2. Concept of fill light
Fill light is generally used to improve the lack of light on the front of the object. This kind of make-up light is generally made of high brightness light-emitting diode (LED). It has the characteristics of stable operation, low heat output, low energy consumption and long service life! As for parameters, they are generally not clearly marked in such products.
3. Led fill light concept
Led fill light is a kind of solid-state light-emitting device, also known as light-emitting diode. It is driven by a small current to light semiconductor devices, with small power consumption and high stability, but the brightness is relatively weak. Less heat, good heat dissipation. It can be close to plants without burning them. Based on this feature, LEDs can be placed horizontally or vertically above plants, so it can greatly reduce the loss of illumination and provide light efficiency.
