Description
Technical field
The utility model relates to field of illumination lamp technology, especially a kind of LED bulb.
Background technology
In recent years, utilize the LED illuminator as light source light fixture get into lighting field in a large number, wherein the LED bulb also has varied; The lampshade that existing LED bulb generally comprises lamp holder and bonds together with lamp holder, the lamp holder place is provided with radiator and led drive circuit, and a plurality of LED lamp bars are set in the lampshade; This bulb can directly be replaced traditional bulb, but because LED lamp bar is within the airtight lampshade, radiating effect is bad; The LED illuminator is operated in the higher temperature; Cause LED to shorten service life, LED can burn out when serious, influences the service life of LED bulb.
The utility model content
The technical problem that the utility model will solve provides a kind of LED bulb, good heat dissipation effect, long service life.
For achieving the above object; The technical scheme of the utility model is: a kind of LED bulb, comprise screw socket, lampshade, ceramic heat-dissipating support, a plurality of LED lamp bar, led drive circuit, and the preceding cross section of ceramic heat-dissipating support is a Y-shaped; The rear portion of ceramic heat-dissipating support is provided with external screw thread; The centre rear of ceramic heat-dissipating support is provided with a containing hole, and led drive circuit is arranged in the described containing hole, and a plurality of LED lamp bars stick on the ceramic heat-dissipating support forward outer surface; Each LED lamp bar is electrically connected with led drive circuit; Led drive circuit connects the two poles of the earth of lamp holder again through lead, the ceramic heat-dissipating support utilizes the external thread rotary at rear portion on lamp holder, and lampshade is mutually bonding with lamp holder again.
Further, the anterior end face of said ceramic heat-dissipating support also can be provided with a Y-shaped LED lamp plate, and the LED lamp plate also is electrically connected with led drive circuit, realizes 360 degree bright dippings, improves the brightness of bright dipping and the uniformity of light.
Above-mentioned LED lamp bar is mutually bonding with the ceramic heat-dissipating support with LED lamp plate heat-conducting glue capable of using, further improves radiating effect.
The utility model is designed to Y-shaped to the preceding cross section of ceramic heat-dissipating support; The rear portion of ceramic heat-dissipating support is provided with external screw thread, and the ceramic heat-dissipating support utilizes the external thread rotary at rear portion on lamp holder, and LED lamp bar is to be attached on the anterior outer surface of ceramic heat-dissipating support Y-shaped; The heat that LED lamp bar distributes just can distribute from lamp holder through the conduction of ceramic heat-dissipating support very soon; Radiating effect is better, can keep LED to be operated in the lower operating temperature, improves the service life of whole LED bulb.
