Bull's eye spotlights:
COB spotlights:
Which one to buy?
COB is a kind of LED lighting optical scheme. The second one is that the first one is the multi-bead scheme. The bull's-eye spotlights are the ceiling lamps that have a certain degree of steering. It is common to say that you are both in principle. As the latter can be called: 5W2.5 inch led ceiling COB bulls eye spotlight ⋯⋯
The multi-bead scheme has no obvious spot boundaries or multiple layers, which is not in line with visual habits. Of course, multi-axis mixed-layer flashlight spots that can change some of the multi-bead schemes through the lens are relatively rare. Most of them are now COB, closer. The traditional light source aesthetic habits are as follows: coaxial multi-layer tapered closing spot. The purchase premise is the same as the multi-bead solution. The COB is directly on the circuit board, with low thermal resistance and good heat dissipation. A lot of packaging steps are reduced, so the material cost is reduced, but the technical requirements are higher.
Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
