The utility model relates to a light emitting diode illuminating bulb for solving the problems of low illumination efficiency, inconvenient maintenance and short service life in the existing bulbs. A spherical lamp housing is composed of an upper lamp housing (1) and a lower lamp housing (2) by butt joint; a groove connected with a reflection cup (3) is disposed on the butt joint point of the upper and lower lamp housing; holes (7) are uniform distributed on the reflection cup (3); a circuit board (4) connected with the reflection cup (3) is disposed in the cavity of the lamp housing (1) on the reflection cup (3); light emitting diodes (5) extend into the cavity of the lower lamp housing (2) under the reflection cup through the holes (7); and the upper lamp housing (1) is connected with a metal lamp holder (6).
Description
Technical field:
The utility model is relevant with light emitting diode illuminating apparatus.
Background technology:
Existing light emitting diode illuminating apparatus is distributed on the installing plate, and installing plate is ordinary flat or arc, the no-reflection layer, and illumination efficiency is not high.Light emitting diode series connection back is connected with power output end, and instant high-voltage of turning on light and big electric current easily make light emitting diode suffer damage.
The utility model content:
The purpose of this utility model has provided a kind of simple in structure, and is with low cost, easy to maintenance, illumination efficiency height, the LED illumination bulb of long service life.
The utility model is achieved in that
The utility model LED illumination bulb, dock with following lamp housing 2 by last lamp housing 1 and to constitute spherical lamp housing, upper and lower lamp housing joint is fluted to be connected with reflector 3, on the reflector 3 uniform porose 7, there is circuit board 4 to be connected in the chamber of the last lamp housing 1 above the reflector 3 with reflector 3, light emitting diode 5 stretches into the cavity of the following lamp housing 2 below the reflector by the hole on the reflector 37, and last lamp housing 1 is connected with metallic lamp holder 6.
Lamp housing 1 has louvre 8, reflector layer is arranged below the reflector 3, and upper and lower lamp housing is connected with the embedding head by caulking groove.
There is the input of regulator rectifier circuit to be connected on the described circuit board with metallic lamp holder, output is connected with the light emitting diode of some series connection, each light emitting diode is in parallel with a divider resistance, has a transient voltage to suppress the output that diode is connected in parallel on regulator rectifier circuit.
Lamp housing of the present utility model adopts the two hemispheres joint construction, and installation and maintenance is convenient, and is with low cost.Reflector makes the attractive in appearance and raising illumination efficiency of bulb.It is in parallel that light emitting diode series connection circuit and transient voltage suppress diode, can eliminate the overvoltage that turn on light instant high-voltage and big electric current cause for the light emitting diode of series connection, heavy current impact, the service life of raising light emitting diode.
Description of drawings:
Fig. 1 is the utility model structure chart.
Fig. 2 is reflecting cup structure figure.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is circuit theory diagrams of the present utility model.
Fig. 5 is the partial enlarged drawing of Fig. 1.
The specific embodiment:
Some louvres 8 are arranged on the last lamp housing 1.Last lamp housing is made of plastics with metallic lamp holder 6 and is connected, and following lamp housing 2 is made by transparent plastic or ring glass.There are 3 interlockings of caulking groove and reflector upper and lower lamp housing junction, and is uniform porose 7 on the plastics reflector 3, the plating reflector layer arranged below it.Printed circuit board (PCB) 4 is arranged on the reflector 3, and the light emitting diode 5 on the printed circuit board (PCB) 4 passes in the chamber that hole 7 enters down lamp housing.The constant current full-wave rectification mu balanced circuit of forming by capacitor C, resistance R 1 and diode D1-D4 on the printed circuit board (PCB).The input of circuit is connected with metallic lamp holder 6, and output is connected with the parallel circuit that transient voltage suppresses diode D5 with the LED 1-LEDn of series connection.
Transient voltage suppresses diode D5 can eliminate turn on light instant high-voltage and LED1-LEDn the overvoltage that light emitting diode cause of big electric current to series connection, and overcurrent impacts; The parameter value that changes capacitor C can change the operating current of LED light emitting diode, the quantity that the parameter value of change diode D5 can mate the LED light emitting diode of series connection; Resistance R 2-Rn is the electric voltage equalization resistance that is connected in parallel on each LED light emitting diode, and the LED light emitting diode is played a protective role.
