Solar LED lighting system technologies and engineering design
The Solar LED lighting is a practical knowledge website that organically combines the design of LED solar lighting system with lighting technologies engineering application
1. Luminous flux Luminous flux Φ is the radiant energy that characterizes the total light output of the LED, and it marks the performance of the device. Φ is the sum of the energy that the LED emits in all directions, and it is directly related to the working current. As the current increases, the…
The light emitted by the LED is not a single wavelength, and its wavelength is basically distributed as shown in Figure 1. It can be seen from Figure 1 that no matter what material is used for the LED, the spectral distribution curve of the LED has the strongest relative light intensity (the maximum light…
The luminous intensity of an LED is a characterization of its luminous intensity in a certain direction. Since the luminous intensity of the LED differs greatly in different spatial angles, it is necessary to study the luminous intensity distribution characteristics of the LED. This parameter is of great practical significance and directly affects the secondary…
