Regarding dot matrix infrared lamps and traditional LED lamps, we can distinguish them from the following aspects:
1. Brightness: The optical output of a single traditional LED lamp is generally about 5-15mW. Although LEDs with 40-50mW or more power are available today, they still cannot compare with single dot matrix LEDs, and because of thermal power. The basic design that does not separate makes its heat dissipation difficult. The optical output of the largest dot matrix infrared lamp can reach more than 2000mW or even higher. That is to say, the sum of the brightness of one or two hundred conventional LED lamps is equal to the brightness of a dot matrix infrared lamp. Therefore, the small part volume can see the object at a long distance.
2. Volume: Since the dot matrix infrared lamp is a highly integrated LED, the volume is much smaller than the sum of LEDs of the same brightness.
3, the angle of illumination: the traditional LED lamp is limited and designed to heat treatment is not good, in order to accommodate heat dissipation, the single light can not be too large, the illumination distance is limited, so it is mostly made at a small angle, concentrated energy to shine far Some, the illuminating angle is generally 8 ° -30 ° angle, so a beam like a flashlight is formed, the central image is too bright and white and the surrounding is too dark to see clearly. The original angle of the illuminator of the dot matrix LED is about 150°, and the angle can be changed by optical means with great flexibility. The entire space can be uniformly illuminated indoors, while other LEDs cannot be used, and the use of ultra-long-distance outdoor products is much smaller than conventional LED products.
4, long life: due to the heat dissipation of the dot matrix infrared lamp is easy to handle and the production materials are different, its life is about five to ten times the life of the traditional LED lamp. In the first two years, the human eye can hardly see the illuminance decay.
5, the quality level of dot matrix infrared lamps is generally military-grade, higher than the industrial grade, of course, higher than the commercial-grade LED. Therefore, it will not be bad under normal use.
Features
A push button switch is a switch that has a knob that you push to open or close the contacts. In some pushbutton switches, you push the switch once to open the contacts and then push again to close the contacts. In other words, each time you push the switch, the contacts alternate between opened and closed. These types are commonly called latching switches. There are also Non latching push button switches that only maintain the switch contacts when the switch is help in position. Once the switch is let go, the current is broken and the switch turns off. Push switches are usually a simple on-off switch.
