Through the continuous efforts of the industry, the breakthrough of new optical design, the development of new light species, and a single situation of products are also expected to further reverse. The improvement of the control software also makes LED lighting more convenient. These gradual changes all reflect the broad prospects of LED light -emitting diodes in lighting applications.

LED is known as the fourth -generation light source, which has the characteristics of energy saving, environmental protection, safety, long life, low power consumption, low heat, high brightness, waterproof, miniature, shockproof, easy lighting, concentration of light beam, simple maintenance, etc. Various instructions, display, decoration, backlight, ordinary lighting and other fields.

LED advantages: high electro -optical conversion efficiency (close to 60%, green and environmentally friendly, long life (can reach 100,000 hours), low work voltage (about 3V), repeated switching and no loss of life, small volume, low heat, high brightness, strong durability, durable, durable, durable, durable, durable, durable, durable, durable, durable, durable, durable, durable, and durable. Easy to adjust, diverse colors, stable beams, and no delay;

LED disadvantages: high starting costs, poor color rendering, low -power LED efficiency, low -flow driver (requiring special drive circuits). In contrast, there are certain defects in various traditional lighting.

Cantile lamp: Low electric light conversion efficiency (about 10%), short life (about 1000 hours), high heating temperature, single color and low color temperature;

Fluorescence Lights: Electric light conversion efficiency is not high (about 30%), harmful environment (mercury containing harmful elements, about 3.5-5mg/size), non-adjustable brightness (low voltage can not be opened), ultraviolet radiation, flashing phenomenon, startup comparison Slow and rare earth raw materials increase (fluorescent powder increases from 10%to 60 ~ 70%), and repeated switches affect life; large volume.

High -voltage gas discharge lights: large power consumption, unsafe, short life, and heat dissipation, mostly for outdoor lighting.
