The utility model discloses simple portable, the heat dissipation is good, can realize the miniaturized of volume of LED ball bubble lamp.
Drawings
Fig. 1 is a schematic perspective view of an LED bulb lamp of the present invention;
fig. 2 is a schematic circuit diagram of the LED bulb lamp shown in fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the LED bulb lamp includes a screw contact assembly 1, a heat dissipation cover 2, a lamp cover 3, an LED light emitter, a driving circuit board, and a battery 4. The screw contact assembly 1 is composed of a screw housing 13, an electrode spacer 12 and a center electrode 11. Screw contact subassembly 1 is connected with heat exchanger 2, heat exchanger 2 surface is opened has a plurality of louvres, heat exchanger 2 bottom surface is equipped with aluminium base board, the LED luminous element is fixed in aluminium base board, lamp shade 3 adopts glass or ceramic material to make, lamp shade 3 is connected fixedly or is fixed through threaded connection through good heat conductivity adhesive with heat exchanger 2 bottom, driving circuit board installs in heat exchanger 2, battery 4 is equipped with two, battery 4 installs in the battery jar of heat exchanger 2 both sides, the battery 4 outside is equipped with battery cover 5, screw contact subassembly 1, driving circuit board, the LED luminous element, battery 4 corresponds the connection.
As shown in fig. 2, the circuit of the driving circuit board includes a rectifier bridge BD, a 220V power supply is used for supplying power to the bulb lamp, 220V alternating current is reduced in voltage by a capacitor C1, then is rectified by the BD through a full bridge, is filtered by a C2, and finally provides a constant current power supply for a plurality of series-connected LEDs through a current limiting resistor R3. R1 is a protection resistor, R2 is a release resistor of a capacitor C1, R3 is a current limiting resistor to prevent voltage rise, temperature rise and current increase of the LED, and C2 is a filter capacitor to protect the LED from impact current when the lamp is turned on. A standby circuit is added in the circuit, so that a battery CC (namely a battery 4 in the figure 1) is connected with the LED in parallel, and the LED bulb lamp can be carried about by using a detachable battery as a driving power supply.
Daily use makes to install LED ball bubble lamp on the lamp stand, inserts the 220V alternating current, and outdoor use or power failure install into the battery jar with battery 4 when emergent, as the drive power supply of ball bubble lamp, cover battery cover 5, LED ball bubble lamp can normally work.
When the LED bulb lamp works, heat emitted by the LED luminous body is transferred to the inside of the heat dissipation cover 2, so that air in the heat dissipation cover 2 is heated and heated, and the pressure is reduced. Because the surface of the heat dissipation cover 2 is uneven, the heat dissipation area is greatly increased, partial heat is transferred to the outside of the bulb lamp through the surface of the heat dissipation cover 2, meanwhile, air enters the heat dissipation cover 2 through the heat dissipation holes of the heat dissipation cover 2 and is discharged out of the heat dissipation cover 2 through the heat dissipation holes, partial heat is taken away, the heat in the heat dissipation cover 2 can be quickly dissipated, heat accumulation cannot be formed, and the conditions of low power, light attenuation, life reduction, faults and the like of the LED bulb lamp can be effectively prevented.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
