Abstract
The light-emitting diode type illuminator is characterized by that several LEDs are set at open of its shell, and fixed by means of sealant, a circuit board is set between the shell and socket, and the stable commutating circuit on the circuit board can be used for controlling application range of voltage, and making it be in 110V-220V, and an exchange oscillating circuit is used for activating LEDs and prolonging their life. It also can use light-colour packaged LEDs, and the light source produced by it can be approached to the illumination of incandescent light.
Description
The present invention is relevant for a kind of LED illumination lamp, is meant especially to utilize a plurality of light emitting diodes (LED) to form, and uses replacement on the market lighting now.
By commercially available and be with the PL lamp for popular employed light fixture on the market, fluorescent lamp and incandescent lamp bulb are main, above-described lamp lighting degree foot, but quite power consumption, spoilage is higher and poor stability, thus need often to change, and increasing purchase is set to originally on foot.
Because the shortcoming that general light fixture uses, the inventor amasss in for many years to be engaged in the relevant industries design experiences, and outstanding planning is had in mind with the illuminating lamp of a low cost, sufficient brightness, and the correlative study of throwing oneself into has the generation of LED illumination lamp of the present invention eventually.
Main purpose of the present invention, promptly be by using the yellow light-emitting diode of light color, it not only can be near white light, and the yellow light-emitting diode cost is cheaply many more than white light-emitting diode, utilize the combination of a plurality of light emitting diodes, can produce sufficient light source and use for the illumination that replaces general light fixture.
A further object of the present invention is to make input range wider with the voltage stabilizing rectification circuit in the circuit board that promptly is to establish in the light fixture, and the alternating voltage scope that supplies the control input is between 110V～220V, so can not be subjected to the restriction of 110V or 220V voltage.
Another object of the present invention is that promptly this switch type oscillating circuit can make the light emitting diode activation, and then improves light-emitting diode luminance, prolongs its service life.
Purpose of the present invention can realize by following mode, a kind of LED illumination lamp, it is characterized in that being provided with a plurality of light emitting diodes in the lamp outer casing opening part, this light emitting diode is also fixed by sealing, between shell and lamp holder, be provided with circuit board, it is characterized in that: the voltage stabilizing rectification circuit on this circuit board can be controlled between voltage scope of application 110V～220V, and make the light emitting diode activation increase the life-span by the switch type oscillating circuit, and the packaged light emitting diode of use light color, supply the light source that produced can be, and reach low cost near the illumination of white light, the light source foot, the light fixture that increase service life.
Now with regard to other purpose of the present invention and detailed construction, will make it more clear and definite by following detailed description, and see also simultaneously shown in the accompanying drawing, it is clear that technology contents of the present invention is further disclosed.
Description of drawings:
Fig. 1 is stereoscopic figure of the present invention;
Fig. 2 is a light structures circuit diagram of the present invention.
See also Figure 1 and Figure 2, the present invention is with sealing 12 fixing a plurality of light emitting diodes 3 in a light fixture 1 shell 11 opening parts, between shell 11 and lamp holder, be provided with circuit board 2, voltage stabilizing rectification circuit 4 and switch type oscillating circuit 5 set on this circuit board 2 are to be connected with light emitting diode 3, utilization with the alternating voltage scope of voltage stabilizing rectification circuit 4 input between 110V～220V, can make the stable 110V that is not powered of voltage or the control of 220V voltage, the voltage stabilizing rectification circuit can adopt bridge rectifier, the switch type oscillating circuit can adopt the LC oscillating circuit, and utilize switch type oscillating circuit 5 can make light emitting diode 3 activation, and then improve the brightness of light emitting diode 3 and can prolong its service life.
Because commercially available white and blue LED 3 cost cost height, so the present invention can select other color to replace white light-emitting diode 3, best selection then is to use yellow light emitting diode 3, in order to meet the illuminating effect of approximate white light (sunshine), this yellow light emitting diode 3 its color when encapsulation can be selected the light color material for use, so that it is light source is approximate fluorescent tube, and softer than the light source that fluorescent tube produced again, not dazzling.
Because of there being yellow slightly light emitting diode 3 to substitute the light emitting diode 3 of white, the unit price price difference of the two is quite big, relative cost is saved many, and the about 0.05W of each yellow light-emitting diode 3 wattage, wattage is very low, has only 1.5W approximately with 30 compositions, but approximate the incandescent lamp bulb brightness of 60W, and institute's power consumption source saving, and the service life of light emitting diode 3 (about 100,000 hours) is quite long, not fragile, and light emitting diode of the present invention 3 is for forming to adopt mode parallel with one another after the series connection, when a light emitting diode 3 damages, do not cause whole light fixture 1 neither bright, all the other light emitting diodes in parallel 3 still can be shinny, can continue to use.
In sum, LED illumination lamp of the present invention, behind long-time continuing, have the advantage that is difficult for producing high temperature, also can increase the service life of light emitting diode relatively, and it is required that its lighting source can meet general illumination, can reach the effect of expection, and meet the important document of novel patent defined, file an application in accordance with the law.
