LED Display Segment :: LED semiconductor with sensitive characteristics

LED drive. LED is a semiconductor device with sensitive characteristics and negative temperature characteristics. Therefore, it is necessary to stabilize and protect it in the application process. LED devices are nearly demanding on the driving power. Unlike ordinary incandescent bulbs, leds can be directly connected to 220V ac mains.

5 pieces of patch LED are welded on the aluminum substrate, and the aluminum substrate is combined with the radiator, so that the heat can be dissipated in time and quickly to ensure that the temperature of LED chip is lower than the allowable junction temperature of LED, so as to ensure the real effective life of LED energy-saving lamps. This kind of LED lamp has high price and good quality, which is also the development direction of LED energy-saving lamps.

The luminous intensity is for the point light source, or the occasion when the size of the luminous body is relatively small compared with the irradiation distance. This quantity indicates the convergent power of the luminescent body emitted in space. It can be said that luminous intensity is a description of how "bright" a light source is, because it is a common description of light power and convergence ability. The greater the intensity of the light, the brighter the light source will appear, and the brighter the object illuminated by the light source under the same conditions. Therefore, this parameter was used in the early description of the torch.
