Talk about that LED light source
Because the LED light source belongs to the spot matrix, it’s combination form light-emitting diode arrangement.
so that any one single LED module is a point light source, and integrated with the LED downlights, spotlights led etc. are regarded as point light source. The ideal state of point light source is a single luminous body and emitter to emit light in all directions, like sun not have sunspots, star in this category is called a perfect point source.We used to live in the point light source are generally light bulbs, lamp beads. Even if they only have a 180 ° angle of the light-emitting surface.in our life The point light source used high power led, led cob, light bulb, lamp etc.. Even if the light-emitting surface they have only 180 degrees angle.LED point light source is the most used light source. energy saving and server time is the best light sources at present. LED operating voltage is very low (about 1 V); the working current is very small (mA can be light); and the good performance of the seismic resistant, impact resistance and high reliability, long service life; current intensity through the modulation(with PWM) can be easily modulated by luminescence intensity.
LED is called the fourth generation light source, with energy saving, environmental protection, safety, long service life, low power consumption, low heat, high brightness, waterproof, shockproof, miniature, easy dimming, beam focus, easy maintenance, can be widely used in various directions, display, decoration, backlightin, general lighting and other fields.LED with high electro-optical conversion efficiency, easy dimming(adjust light), color variety, low operating voltage, repeatedly switching not destructiveness of led life, less heat, durable, small size, high brightness, concentrated light beam stability, no delay to start, etc.
But it also has the same problem we need to solve, the LED initial cost is too high, color difference, low efficiency, high power LED constant current driving. To make a long story short, compared with the traditional light source, LED light source is bound to replace the traditional light source advantage products, as ledlightmake has a shaky enterprise, light up the world.
