Description
Technical field
The utility model relates to a kind of lighting, relates in particular to a kind of LED advertising lamp.
Background technology
LED can directly be converted into light to electricity; The heart of LED light fixture is LED; The heart of LED is a semiconductor LED wafer; LED (the Light-Emitting-Diode Chinese meaning is light emitting diode) is a kind of semiconductor that can electric energy be converted into visible light, and it has changed the luminous and luminous principle of electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and adopts electroluminescence.According to one's analysis, the characteristics of LED are very obvious, and the life-span is long, light efficiency is high, radiationless and low-power consumption.
LED and ordinary incandescent lamp, spiral energy-saving lamp and T5 three-color fluorescent lamp are compared, and the result shows: the light efficiency of ordinary incandescent lamp is 12lm/W, and the life-span was less than 2000 hours; The light efficiency of spiral energy-saving lamp is 60lm/W; Life-span, the T5 fluorescent lamp then was 96lm/W less than 8000 hours, and the life-span is approximately 10000 hours; Can surpass 150lm/W and diameter is 5 millimeters a white light LEDs light efficiency, the life-span can be greater than 100000 hours.Someone predicts that also following LED life-span upper limit is with infinity.
High-power, refer to that luminous power is big, refer generally to 0.5W, 1W, 3W, 5W or higher.Light intensity is bigger than small-power with lumen, but same heat radiation is also very big, and existing great power LED advertising lamp all is single application, need add very big fin, causes the light fixture volume bigger than normal, and weight lays particular stress on.The fin volume-diminished; Will cause heat radiation bad; Can cause the decay in service life of LED, brightness reduces, even does not reach normal illumination and optical effect; Existing LED advertising lamp water resistance and anti-dust performance are relatively poor simultaneously, are difficult to guarantee that the obverse and reverse of LED advertising lamp has identical intensity of illumination and range of exposures.
The utility model content
The technical problem that the utility model solves is: a kind of LED advertising lamp is provided, can improves heat dispersion, water proof and dust proof performance and range of exposures.
The technical scheme of the utility model is: a kind of LED advertising lamp; It is characterized in that, comprise heat-dissipating casing and be installed in the LED lamp plate in the said heat-dissipating casing, wherein; Two opposing sidewalls of said heat-dissipating casing are equipped with through hole; Said LED lamp plate comprises printed circuit board (PCB), and the front and back of said printed circuit board (PCB) all is equipped with LED lamp pearl, and each LED lamp pearl is covered with optical lens outward respectively; Each optical lens and said printed circuit board (PCB) fix, and each optical lens is exposed to respectively in the through hole of radiator.
Two opposing sidewalls of said heat-dissipating casing are respectively equipped with three through holes, and the obverse and reverse of printed circuit board (PCB) is respectively equipped with three LED lamp pearls.
Said printed circuit board (PCB) is connected with insulated electric conductor, and said insulated electric conductor extends said heat-dissipating casing.
The material of said heat-dissipating casing is a plastic cement.
The beneficial effect of the utility model is: the novel optical lens of this use is set directly on the printed circuit board (PCB); LED lamp integument covers in the optical lens; Change optical lens of the prior art and be installed in the structure on the shell; Improve LED advertising lamp water resistance and anti-dust performance, adopted heat-dissipating casing simultaneously, can improve the heat dispersion of LED advertising lamp; And the front and back of printed circuit board (PCB) all is equipped with LED lamp pearl, thereby makes the obverse and reverse of LED lamp all have identical intensity of illumination and range of exposures.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the exploded perspective view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1, Fig. 2, a kind of LED advertising lamp comprises heat-dissipating casing 1 and is installed in the LED lamp plate in the heat-dissipating casing 1; Wherein, two opposing sidewalls of heat-dissipating casing 1 are equipped with three through hole 1a, and the LED lamp plate comprises printed circuit board (PCB) 2; The front and back of printed circuit board (PCB) 2 all is equipped with three LED lamp pearls 3; Be covered with an optical lens 4 respectively outside each LED lamp pearl 3, each optical lens 4 fixes with printed circuit board (PCB) 2, and six optical lenses 4 are exposed to respectively among the through hole 1a of six radiators.Printed circuit board (PCB) 2 is connected with insulated electric conductor 5, and insulated electric conductor 5 extends heat-dissipating casing 1.The material of heat-dissipating casing 1 is that the material of heat-dissipating casing 1 is plastic cement, and the trade mark of plastic cement is PVC730 G-90073K-95A (PVC730 UL94V0, anti-UV is the Containing Sulfur material not).Can realize a plurality of LED-backlit lamp series connection or connect the LED driving power lighting the LED-backlit lamp through insulated electric conductor 5.
