As shown in Figure 1 to Figure 3, LED bulb described in the utility model comprises lamp holder 1, LED power 2, LED light source 3 and lampshade 5, LED power 2 is electrically connected with lamp holder 1, LED light source 3 respectively, and LED light source 3 is provided with LED chip 31, and LED chip 31 is UV LED chip or blue-light LED chip; Lampshade 5 comprises lens jacket 51 and fluorescent coating 52, and fluorescent coating 52 is located at the medial surface of lens jacket 51.
Above-mentioned LED bulb, by arranging the fluorescent coating 52 being positioned at medial surface in lampshade, can have following effect:
1, use large-area fluorescent coating 52, relative to the multiple LED chip using the packaging plastic being mixed with fluorescent material to carry out encapsulation separately, realize becoming face luminescence by a luminescence, luminous efficiency is high, uniform light, soft, therefore, relative to the LED bulb using light-transmissive film, energy consumption can be reduced;
2, can not the packaging plastic being mixed with fluorescent material be set in each LED chip 31, thus reduces production cost, technology difficulty;
3, be convenient to change the lampshade 5 with different fluorescent coating, due to the colour temperature or the color difference that use the fluorescent coating of different fluorescent material can cause the light of bulb, thus realize user carries out colour temperature or color to light adjustment by replacing lampshade 5, use very flexible.
Above-mentioned LED bulb adopts UV LED chip or blue-light LED chip, and corresponding matching has the fluorescent coating 52 of different fluorescent material respectively, can make to send ultraviolet light or blue-light excited corresponding light-emitting phosphor by LED chip, thus sends white light.
Above-mentioned fluorescent coating 12 adopts dipping process to be processed to form, be specially: fluorescent material slurry is poured in transparent lamp shade (only containing lens jacket 51), make the inwall of transparent lamp shade speckle with fluorescent material slurry comprehensively, on the inwall of transparent lamp shade, form fluorescent coating 52 after drying.
The lens jacket 51 of above-mentioned lampshade 5 is glassy layer or heat-conducting plastic layer.The shape of lampshade 5 can be spherical or candle etc.
