What is the difference between an infrared emitter and a patch diode?

   Let us first look at the characteristics of the infrared emission tube? The angle of the infrared emission tube is very small, and the light is concentrated, the range is very long, but the illumination range is limited; and the general angle of the patch diode is very large, and the light is relatively scattered, the illumination range is wide, but the range is compared. near. The infrared emission tube uses discharge discharge, and the chip diode is used for cold illumination.

In contrast, what are the advantages of SMD diodes? The chip diode is also a kind of infrared emission tube. Commonly there are two or four pins, and some have no pin-shaped feet, which are the same as the soldering of the circuit board copper foil. The key to choosing a lamp bead is to consider the color temperature, color rendering index, light efficiency, light decay, and the quality of the power supply. Buy these things and buy better quality.

  Where is the difference between them? There are many forms of chips for infrared emission tubes, which are mainly formulated in consideration of heat dissipation forms of various powers. You find a salesman on the Internet who is a manufacturer of chips, ask them for a piece of information, and then ask them to find out, they will understand very transparent.

Detailed explanation of the advantages and disadvantages of each:

  What is the advantage of the infrared emission tube? Cob in the lamp. The shape of the infrared emission tube has undergone direct insertion and chip diodes. With the advancement of technology, it has become apparent that a plurality of light-emitting chips are highly integrated and directly packaged on the substrate to form a compact, high-power, ultra-high-power light-emitting element. "COB".

And for the chip diode, what is its advantage? Integration is generally a different name for COB light sources on the market, but in fact, the characteristics of COB light sources cannot be clearly described. COB refers to Chip-On-Board, which directly encapsulates a small power chip onto an aluminum substrate for rapid heat dissipation. The chip area is small, the heat dissipation efficiency is high, and the driving current is small. Therefore, it has high heat dissipation with low thermal resistance and high thermal conductivity.

  If the light is on, it means that the function of the lamp bead is basically unaffected. If it is not lit, exchange the red and black test leads and test again. In order to avoid the anode and cathode of some lamp beads, the opposite is true. The lamp bead lights to observe the color of the lamp bead, and the color temperature meets the requirements. Is the brightness appropriate? Choose the right lamp bead. Therefore, we find that each of them has its own advantages.

  In summary, 3MM infrared emission tubes and patch diodes each have their own advantages. When you are interested in buying lighting, you can purchase different styles and different types of products according to your choice. Speaking of infrared emission tubes and SMD diodes, their use range is not the same. At this time, everyone can purchase according to their own needs.
