LED lighting angle knowledge-EEWORLD

Collect

Diode Emitting angle That is, the angle of light scattering, which is mainly controlled by adding scattering agents during diode production. There are three categories:

1. High directivity

Generally, it is a pointed epoxy package, or a package with a metal reflective cavity, and no scattering agent is added. The luminous angle is 5°~20° or less, with high directivity, and can be used as a local lighting source, or used in conjunction with a light detector to form an automatic detection system.

2. Standard type

It is usually used as an indicator light, and its luminous angle is 20°~45°.

3. Scattering type

This is an indicator light with a larger viewing angle, a light emitting angle of 45°~90° or larger, and a larger amount of scattering agent.

Analysis of two major technical risks in LED indoor lighting

Since the first commercial LED was launched in the 1960s, LED has been used in the lighting industry for more than 40 years. A relatively complete industrial chain has been formed in the upstream, midstream and downstream of the industry. LED is being used in more and more industries, especially in the field of indoor

STM8 self-study notes-002 continue to light up the LED

　　Light up the LED 　　Lighting up an LED should be the first step in most microcontroller tutorials. This is the most basic step and the most exciting step. Taking this small step is a big step into the door of STM8. 　　Usually, the LED can be lit only by setting the mode and level of the microcontroller pin where the

Drives two low quiescent current LEDs from only one microprocessor pin

Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor. This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input high impedance or output to drive two LEDs independently (Reference 1). The idea sounds good, mainly because the micropro

LED thermal isolation packaging technology and improvement of optoelectronic performance

In the traditional white light LED packaging structure, the phosphor is directly coated on the chip. When working, the heat released by the chip is directly loaded on the phosphor, which leads to the temperature rise of the phosphor and reduces the conversion efficiency of the phosphor at high temperature.
