Led(Light Emitting Diode)

LED products and little common sense

Leds (Light Emitting Diode) is an able to convert electric power into the visible semiconductor, it has changed the incandescent lamp glow and tungsten energy-saving sanki pigments glowing principle, and use electric field to shine. According to the analysis, the LED characteristics very prominent, long service life, high efficiency and low consumption, no radiation. LED spectral almost exclusively focused on visible spectrum, the luminous efficiency can be over 150lm/W (2010). Will LED with ordinary incandescent lamp, spiral energy-saving lamps and T5 three colors fluorescent lamp, comparing the result shows: the normal bulb efficiency for 12lm/W, life is less than 2000 hours spiral energy-saving efficiency for 60lm/W, life is less than 8000 hours, T5 fluorescent is 96lm/W, life span is about 10,000 hours and the diameter of 5 millimeter of white LED lights can exceed 150lm/W, life can be more than 100,000 hours. Someone also predict that future LED life cap will be infinite.

High power, refers to shine in power, generally refers to 0.5 W, 1W leds 3W 5W or higher. Light intensity lumens is better than small power, but also heat is very big also, now high-power are single application, add big heat sink. Small power is usually about 0.06 W. The plugin and man-eating fish etc. Now LED flashlight is commonly used in small power, light scatter not scattered, depends on the LED light emitting Angle, have large Angle of small Angle of points, small Angle scattered, large Angle only scattered. The flashlight on market is usually use straw hat head. The effect is very good. Now worry some manufacturer is not heavy quality, take the defective LED flashlight do, can't use how long is the death lamp.

LED(Light Emitting Diode)

LED  = Light Emitting Diode, Emitting Diode,is a kind of can convert electric power into the visible solid-state semiconductor device, it can directly put DianZhuan into Light. LED = about Electronic put, Large Electronic Display, LED disseminatus, spread erythematosus = showed sexual Lupus erythematosus, a chronic, idiopathic autoimmune disease, Leds are organization past tense and past participle, meaning "leadership, lead."
