Causes of high brightness of led digital tube

Light efficiency of led beads for lamps. Different input currents will make LEDs have different light effects, and reducing power supply current is often more effective than full power supply. High brightness and high light efficiency under the same power.

2. The led inside the lamp is connected in series and parallel. The number of LEDs with the same light efficiency is less in parallel and more in series, which requires less input current. At this time, even if the input current is small, the brightness of LED lamp beads will be higher.

3. Lamps use different types of light sources, and the light efficiency of the same input current is high or low. There are 120lm/w and 80lm/w bulbs in the market, and the power supply current is the same.

Extended data:

LED(Light Emitting Diode) is a solid semiconductor device that can convert electric energy into visible light, and it can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to the bracket, one end is the negative electrode, and the other end is connected to the positive electrode of power supply, so that the whole chip is encapsulated by epoxy resin.

Features of LED lamp:

1, energy saving: the energy consumption of white LED is only110 of incandescent lamp and 1/4 of energy-saving lamp.

2. Long service life: the service life can reach more than 65,438+10,000 hours, which can be described as "once and for all" for ordinary household lighting.

3, can work in a high-speed state: if the energy-saving lamp is frequently switched on and off, the filament will turn black and break down quickly, which is safer.

4. Solid-state packaging belongs to the type of cold light source. Therefore, it is easy to transport and install, and can be installed in any miniature and enclosed equipment without worrying about vibration.

5.led technology is changing with each passing day, the luminous efficiency is making an amazing breakthrough, and the price is also decreasing. The era of white LED entering the home is rapidly coming.

6, environmental protection, no harmful substances containing mercury. The assembly parts of LED bulbs can be easily disassembled and assembled, and can be recycled by others without recycling by manufacturers.

7. Light distribution technology expands LED point light source into surface light source, increases luminous surface, eliminates glare, sublimates visual effect and eliminates visual fatigue.
