Abstract
The utility model relates to an LED illuminating lamp, comprising a plurality of LEDs and a drive circuit for driving the LEDs to illuminate which are integrated on a printed circuit board with a length of 585mm, a width of 18.4mm, a thickness of 1.6mm. Due to integration of the LEDs and the drive circuit on a printed circuit board, the LED illuminating lamp has higher integration level and smaller volume.
Description
Technical field
The utility model relates to a kind of illuminating lamp, relates in particular to a kind of LED illuminating lamp.
Background technology
Generally adopt fluorescent lamp in traditional lighting lamp, it utilizes the noble gas discharge in the fluorescent tube, make the light-emitting phosphor of tube inner wall, there have been very big progress in its light efficiency, life-span than incandescent lamp, but power consumption is still bigger, and harmful chemical such as mercurous can pollute environment in its fluorescent tube; Now, the LED light emitting diode that integrates numerous advantages is used in the illuminating lamp just gradually, and LED utilizes electroluminescence, has the light efficiency height, numerous advantages such as long, low-power consumption of radiationless, life-span and environmental protection, but the most structure of existing LED illuminating lamp is complicated, and also integrated level is not high.
Summary of the invention
Based on the deficiencies in the prior art, problem to be solved in the utility model provides a kind of integrated level height and the little LED illuminating lamp of volume.
For addressing the above problem, the utility model provides a kind of LED illuminating lamp, the drive circuit that it comprises several light emitting diodes and is used to drive described lumination of light emitting diode; Described several light emitting diodes and drive circuit are integrated on the printed circuit board.
Particularly, the number of described light emitting diode is 140; The power bracket of described light emitting diode is between 8 watts to 10 watts, and luminous flux is not less than every watt 70 lumen.
The length of described printed circuit board (PCB) is 585 millimeters, and width is 18.4 millimeters, and thickness is 1.6 millimeters.
LED illuminating lamp of the present utility model is integrated in light emitting diode and drive circuit on one printed circuit board, make integrated level higher, and volume is littler.
Describe the utility model in detail below in conjunction with accompanying drawing, it illustrates principle of the present utility model as the part of this specification by embodiment, and other aspects of the present utility model, feature and advantage thereof will become very clear by this detailed description.
Description of drawings
Fig. 1 is the schematic diagram of a kind of LED illuminating lamp among the utility model one embodiment;
Fig. 2 is the circuit diagram of a kind of LED illuminating lamp among the utility model one embodiment.
The specific embodiment
Fig. 1 is that a kind of LED illuminating lamp of the utility model specific embodiment is integrated in the schematic diagram on the printed circuit board; As shown in the figure:
A kind of LED illuminating lamp, it comprises light emitting diode group of being made up of 140 light emitting diodes (LED) 11 and the drive circuit 12 that is used to drive described lumination of light emitting diode.
Particularly, described light emitting diode group 11 and drive circuit 12 are integrated on the printed circuit board 1.
Described 140 light emitting diodes are connected into two rows on printed circuit board (PCB) 1,70 light emitting diodes of every row, and the length of printed circuit board (PCB) 1 is 585 millimeters, and width is 18.4 millimeters, and thickness is 1.6 millimeters.
That above-mentioned 140 light emitting diodes adopt is the LED of 3020 series, and this serial LED has that light-emitting area is big, and lighting angle is big, characteristics such as brightness height, and brightness can reach more than the 1400-1800mcd; Particularly, its power bracket is: 8W-10W, and input voltage: AC85-264V, the luminous flux of LED is not less than 75lm/W.LED illuminating lamp of the present utility model uses the LED of 140 3020 series just can reach the brightness and the illumination of traditional 17W fluorescent lamp, and does not need to add in addition ballast.
Fig. 2 is the detailed circuit diagram of drive circuit 12 and light emitting diode group 11 among Fig. 1.The input of drive circuit 12 connects the alternating current of civil power, and output connects light emitting diode group 11, and 140 light emitting diodes in the light emitting diode group 11 are connected successively.
Particularly, become the direct current of 300V after the civil power process protective tube F1 of input and the bridge heap SW1B rectification, through giving U2 (LED drive IC-SMD802) power supply after D1 and the R1 step-down, SMD802 is that a LED of PWM efficiently constant current drives application design use IC, at this moment the square wave of a PWM of 4 pin of U2 generation makes the Q1 conducting, the electric current of LED feeds back to 2 pin of U2 through R3, make the electric current can be invariable through the size of relatively exporting PWM of the inside of U2, L1 is an energy storage inductor, D7 is a fast recovery diode, CE4 is an output filter capacitor, CE1, CE3, D5, D4, D2 constitutes pfc circuit, utilize pfc circuit can improve utilization ratio to electric energy greatly, wherein SMD802 can drive the LED series connection of up to a hundred high brightness or the LED of string high brightness; It is by regulating the service life that constant current value can be guaranteed brightness and the spectrum of LED and prolong LED.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
