Abstract
The utility model discloses an LED bulb, which is characterized in that one end of a capacitor and one input end of a bridge rectifier are all connected with a lamp cap; the other end of the capacitor is connected with the other input end of the bridge rectifier; a circuit board is also arranged in a shell; a plurality of luminous tubes connected in series are arranged on the circuit board; two output ends of the bridge rectifier are respectively connected with both ends of the luminous tubes. The bulb has the characteristics of power consumption saving, small heat generation, long lifetime, shock resistance and difficult breaking.
Description
The utility model relates to the technical field of bulb, specifically a kind of bulb of being made of matrix luminous tube.
Existing lighting is mainly fluorescent lamp and ordinary lamps, and fluorescent lamp has flickering, and starter easily damages, and common bulb exists power consumption big, and it is big to produce heat, and the life-span is short, easy deficiency such as fragmentation.
The purpose of this utility model is to provide a kind of luminous tube bulb, and its power saving is not glimmered, and the life-span is long.
The technical solution of the utility model is achieved in that the LED bulb, it mainly comprises lamp holder, be located at the housing on the lamp holder, be contained in the bulb in the housing, be contained in the light cover on the housing, it is characterized in that: an end of capacitor all is connected with lamp holder with bridge rectifier one input, and the other end of capacitor is connected with another input of bridge rectifier; Also establish a circuit board in housing, the luminous tube of several series connection is housed on circuit board, two outputs of bridge rectifier are connected with the two ends of luminous tube respectively.
The utlity model has the power consumptive province, it is little to produce heat, and the life-span is long, and is shock-resistant, not broken up characteristics.
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is an electrical connection diagram of the present utility model
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises lamp holder 7, be located at the housing 2 on the lamp holder 7, be contained in the bulb in the housing 2, be contained in the light cover 1 on the housing 2, it is different from prior art: an end of capacitor 6 all is connected with lamp holder 7 with bridge rectifier 5 one inputs, and the other end of capacitor 6 is connected with another input of bridge rectifier 5; In housing 2, also establish a circuit board 3, the luminous tube 8 of several series connection is housed on circuit board 3, the luminous tube that present embodiment is connected on circuit board is a light emitting diode, and the preferred number of luminous tube is 10-200, and two outputs of bridge rectifier 5 are connected with the two ends of luminous tube 8 respectively; In order to adapt to some temperature height, environment that voltage is high, output of bridge rectifier 5 with also can adorn a protective tube 4 between an end of luminous tube 8 is connected, fuse in the protective tube 4 of Shi Yonging is from the renaturation fuse in an embodiment, even overtension occurs, environment temperature is crossed high deadly condition, after fuse disconnects, all can recover voluntarily, guarantee to use, housing can adopt the PBT plastic casing, and lamp holder can be made screw socket and socket type.
