6 advantages of LED flat panel soft light in news studio

The LED flat panel soft light produced and developed by VanGaa Lighting sells well at home and abroad, and has been well received by customers. Today, let's talk about its major advantages.

1 Soft and uniform light quality

In terms of physical structure, LED panel lights have the same characteristics as tri-color fluorescent lamps, all of which are scattered light. At present, the light-emitting methods of LED panel lights are mainly LED light-emitting diode arrays and LED modules plus reflector bowls. Add a layer of diffuser to the surface of the lamp. Either way, the light emitted is softer and more uniform, and the light quality is "softer". The light-emitting area can be controlled by the shutter and honeycomb grille in front of the luminaire to avoid the scattering of stray light (commonly known as "wild light"). It can meet the requirements of uniform lighting and soft skin tone of characters in news programs.

2 Energy saving and environmental protection

LED lamps are fundamentally different from traditional tungsten filament lamps in terms of structure and light-emitting principle. The basic principle of LED light emission is that after a forward bias voltage is applied across the PN junction, the holes and free electrons move with each other to form an internal electric field; then, the newly injected holes and free electrons recombine, and when they recombine, they will be recombined with photons. The excess energy is released in the form of , which is the light emitted by the LED that the user sees. The light-emitting principle of LED determines that its energy conversion efficiency is very high. In theory, it can save nearly 90% of energy than traditional halogen tungsten lamps and nearly 50% of energy than tri-color soft light lamps. The energy-saving effect is very significant.

3 long service life

The traditional tungsten halogen lamp filament is easy to break, while the LED uses a solid-state semiconductor chip to convert electrical energy into light energy, which is more durable and can withstand high-strength mechanical shocks. Under normal use, the LED panel light has a lifespan of up to 50 000 h, which reduces lamp replacement and other maintenance work to a certain extent.

4 High luminous efficiency

Theoretically, the luminous efficiency of white LEDs can reach nearly 300 lm/W. If it is compared with other light sources according to the luminous efficiency of 150 lm/W, the luminous efficiency of LED is 11.5 times that of incandescent lamps (131 lm/W luminous efficiency under the same conditions), which is higher than that of high-pressure sodium lamps, which are generally considered to have the highest luminous efficiency. (132 lm/W) even higher.

5 pure light color

LED PAR lamps were first used for dyeing effects. LED has shown its absolute advantage in light color. At present, color LED products on the market have been able to cover the entire visible spectrum range, and at the same time have the characteristics of good monochromaticity and high purity. With the development of LED light source, its color rendering index has gradually increased. The improvement of the color rendering index enables the LED panel light to restore the skin color of the characters close to or even beyond the traditional three-color fluorescent light.

6 Less radiant heat

Although the current LED chip cannot convert all the electrical energy into light energy, due to the PN junction luminescence characteristics of the LED light source itself, the amount of infrared thermal radiation is smaller than that of traditional halogen tungsten lamps and computer lights, and it is a cold light source. Makes the host to avoid the high temperature and heat under the lights.
