Background technology
LED (semiconductor light-emitting-diode) is the third generation semiconductor illuminating light source after incandescent lamp and fluorescent lamp.Domestic and international expert's prophesy: semiconductor lighting will be 21 century one of maximum, most active high-tech industry, be extremely important aspect economic competition and the national security.Along with the appearance of red, green, blue, White-light LED illumination lamp, a fight of seizing semiconductor lighting new industry commanding elevation is fired in the whole world.
China is a Lighting Industry big country, but is not a Lighting Industry power.At present, China's illumination in year power consumption surpasses 2,000 hundred million kilowatt hours, accounts for 12% of national power consumption.If the LED illuminating lamp can be saved nearly 1,000 hundred million kilowatt hours every year after substituting the traditional lighting lamp fully, the generating total amount in the power station, Three Gorges after building up above 2008.
The LED illuminating lamp because have optical efficiency height, light quality height, advantage such as energy consumption is little, the life-span is long, reliability and durability, applying flexible, safety, environmental protection, response time are short, will become another significant qualitative leap after incandescent lamp and fluorescent lamp on the illumination history.
At present, the LED illuminating lamp all is by trunking mode several monomers LED encapsulation to be formed.Specifically, as Fig. 1, Fig. 2, the LED illuminating lamp is made up of printed circuit board (PCB) 2, LED3, lamp holder 4, shell 5, lead 6; Lamp holder 4, shell 5, printed circuit board (PCB) 2 connect successively, and printed circuit board (PCB) 2 is provided with LED3.And all LED3 are line, face encapsulation.The heat radiation of LED illuminating lamp all is to solve by the heat radiation of the copper sheet on the double-sided printed-circuit board 2, because the area of copper sheet is limited, and is enclosed in again in the shell 5, makes the radiating effect extreme difference, and then causes encapsulating material aging, and the LED lighting brightness descends.Because it is quite big always to solve the difficulty of heat dissipation problem, has seriously restricted the raising of LED illuminating lamp power.
Summary of the invention
The purpose of this utility model just is to overcome the problem and shortage that prior art exists, and a kind of LED illuminating lamp that has metallic heat radiating plate is provided.
The purpose of this utility model is to realize like this.
As Fig. 3, Fig. 4, Fig. 5, the utility model mainly is made up of metallic heat radiating plate 1, printed circuit board (PCB) 2, LED3;
Be welded with 1, two metallic heat radiating plate 1 of metallic heat radiating plate on the two sides of printed circuit board (PCB) 2 respectively and be provided with LED3, obtain the linear LED illuminating lamp of a unit;
Linear LED illuminating lamp or the series connection or the parallel connection of a plurality of unit are combined into or for linear, or are the LED illuminating lamp of face shape.
Its operation principle is:
The two poles of the earth of LED 3 light emitting diodes are welded on respectively on two adjacent metal heat sinks 1, and metallic heat radiating plate 1 and double-sided printed-circuit board 2 are connected together by molten soldering, make metallic heat radiating plate 1 and double-sided printed-circuit board 2 electrical communication.
When power supply inserts double-sided printed-circuit board 2 by lead 6, again by circuit rectification, transformation, it is electric that metallic heat radiating plate 1 is got, thereby cause LED3 luminous.
The utlity model has following advantage and good effect:
1. good heat dissipation.Be provided with LED 3 between two adjacent metal heat sinks 1, metallic heat radiating plate 1 has favorable conductive function and better heat radiating effect, makes LED 3 luminous, thereby has improved its luminous efficiency and prolonged its service life.
2. power is big.Because metallic heat radiating plate 1 good heat dissipation, the power of LED illuminating lamp is done becomes possibility greatly.
3. designs and varieties are many.The utlity model has linear and face shape basic structure, make the LED illuminating lamp can make the designs and varieties of a lot of shapes, a lot of specifications, satisfy social various demand.
