LED, LED because of the different luminous principle, eliminate the stroboscopic and has high photosynthetic efficiency and pursue higher photosynthetic efficiency potential Advantage is small volume, no stroboscopic, including UV, high light efficiency, using high quality chip (OSRAM, day, and the name of the CREE) products can reach more than 80 or 80 color and has a long life The disadvantage is that the current national standard uncertainty, the products on the market anomalies chaos, most manufacturers use inferior chip led to less than 50 color... And LED chip due to poor use drive electric power are different, such as chip array and flashing brightness difference problem In a word, If conservative and don't care under the condition of light, it is best to use halogen light source to read; Care about energy saving problem use energy-efficient light bulbs, but must pay attention to choose big, because of the small manufacturer use halogen powder phosphor color rendering index less than 70, the same is not suitable for reading; If the pursuit of high-end, strict energy-saving, wish longevity noodles and the modelling of traditional light source, can choose LED products, but the best choice in the lighting industry's top brands and formal channel, so as to the quality of the products
?the progress of the halogen lamp is incandescent lamp, full of halogen gas in vacuum bubble has realized the halogen tungsten filament with gas circulation and greatly prolong the service life of the filament, perfect inherited the color rendering of the incandescent light bulb 2, energy-saving lamps, CFL (compact fluorescent lamps, the actual domestic called the lamp energy-saving lamps have a little not science...). CFL is a great invention, the field of electric light source characteristics can be made into any color temperature and high color rendering, due to the effect of glow of the phosphor powder, stroboscopic can ignore (low temperature is a problem). Advantage is high luminous efficiency, such as 11 w CFLS can completely replace 60 w incandescent lamp, and use tricolor phosphors CFLS can reach more than 80 color rendering, some high-end products can reach more than 90 The disadvantage is that the fluorescent tube is filled with mercury vapour, how to environmental protection is a big problem in manufacturing and recycling, partly responsible manufacturer in tube using mercury pills (haha, suspected of advertising), partly solved this problem... P. : energy-efficient light bulbs are more likely to buy on the market at present stage is cost-effective light source
