Why not see the OTC Sales semiconductor light energy saving and environmental protection

Editor comrade: Recently, I often see in the media of LED semiconductor light is energy saving and environmental protection products reported, said it low power consumption, long service life. Energy saving and environmental protection is a good thing, but I should be promoted, in many supermarkets, stores do not buy LED semiconductor light home, shopping malls ask the relevant personnel, also can not get the exact answer. What is the reason, hoping to get help. Reporter according to the reader's question, the reporter recently interviewed Mr. Shi Shanchang, Shanghai excellent science writer. Shi introduced, LED semiconductor lamp is a new type of lighting fixtures. A semiconductor device has the advantages of power saving, durable advantages, we have the experience, before the transistor radio to use 220V, and easily damaged, and later with the radio, as long as a few batteries, for a long time is not bad. LED semiconductor lamp is a solid-state device that can directly convert electrical energy into light energy, has the characteristics of long service life and energy saving, but the LED semiconductor lamp also has its shortcomings, especially the high production cost, so it is more difficult to popularize, a light bulb hundreds of yuan, who buy ah?! Therefore, it is not possible to mass produce and supply the civil market. In addition, unlike the LED semiconductor lamp fluorescent lamp as the whole surface of the lamp tube are light, but a "point of light, as traffic lights, landscape lighting is very appropriate, but you want to use for the family room lighting, to" point "as" face ", the effect is not ideal at present. Mr. Shi said, now many experts in the field of electric light source is hard work, to solve the related technical problems, I believe that in the near future, this new LED semiconductor lamp technology products will be able to fly into the homes of ordinary people".
