What is the difference between a LED dot matrix and an ordinary LED lamp?
The quality grade of dot matrix infrared lamp is generally higher than military grade, industrial grade, certainly higher than the general use commercial grade LED. Simply put, under normal use, it won't be bad.
Long life: as the dot matrix infrared radiating easy processing and production of different materials, their life expectancy is about five to ten times the life of traditional LED. In the first two years, the human eye almost can not see the attenuation of illumination.
Light angle: the traditional LED with limited design and heat treatment to poor heat dissipation, light emitting single can not be too large, irradiation distance will be limited, so how to make a small angle, in order to concentrate energy as well, the light angle is 8 degrees -30 degrees, so the formation of a as a flashlight beam, the central image too bright and white and dark around to see clearly. The light of the matrix LED is about 150 degrees from the original angle, and can be changed by optical means at different angles, and the flexibility is great. The room can be evenly lit all the space, while other LED beam can not be achieved, and the use of ultra long distance outdoor, the volume of its overall product is much smaller than the traditional LED products.
Volume: because the dot lamp highly integrated (highlyintegrated) LED, the volume ratio of the same brightness of the LED sum of small lot.
Brightness: a single optical output of traditional LED is generally about 5-15mW, although there are 40-50mW or more power LED asked the city, but still not with single dot compared to LED, and because the basic design of thermal power separation. It is not easy to heat treatment. The optical output can reach the maximum of the lattice type infrared lamp above about 2000mW, or even higher. That is to say the brightness of one hundred or two hundred traditional LED brightness equivalent to a sum of the dot matrix infrared lamp. As a result, small parts can see objects at a very long distance.
