Abstract
The invention provides a light-emitting diode (LED) lamp device with two-sided illumination, which is characterized in that the first holding space of a first guide rail and the second holding space of a second guide rail are respectively formed at the two opposite sides of a radiating substrate, wherein the first holding space and the second holding space correspond to each other; two LED illuminating modules are respectively fixed behind the first holding space and the second holding space; and two lamp shades respectively cover the first holding space and the second holding space of the radiating substrate so as to cover the two LED illuminating modules, thus the two LED illuminating modules can provide the illumination for the two opposite sides. The LED lamp device has good radiating effect and reaches the technical effect on increasing the illumination range of the LED lamp device.
Description
Technical field
The present invention is a kind of LED lamp device with two-sided illumination, is meant a kind of LED lamp device that the two-sided illumination of illumination can be provided in relative both sides especially.
Background technology
In daily life, lighting apparatus all is indispensable visual plant all the time, existing lighting apparatus be mostly with bulb or fluorescent tube as main light source, and in these fluorescent tubes or the bulb, comparatively common person has fluorescent tube, incandescent lamp bulb, halogen lamp tube or based on halogen bulb.Wherein, because the power consumption and life-span of fluorescent tube all is much better than incandescent lamp bulb, and the uniformity of luminance of fluorescent tube is also preferable, so comparatively widely-used.
Below a kind of existing fluorescent lamp lighting equipment of explanation please refer to Fig. 1, and Fig. 1 comprises: fluorescent tube 10 and lamp socket 20 for the STRUCTURE DECOMPOSITION figure of existing fluorescent lamp lighting equipment.Wherein, fluorescent tube 10 has lamp tube body 11 and pair of metal end 12, and metal end 12 respectively is provided with pair of electrodes joint 13; 20 of lamp sockets are made up of lamp socket body 21, pair of electrodes seat 22 and starter 23, and described electrode tip holder 22 is arranged at lamp socket body 21 both ends, and possesses pair of electrodes jack 24.When reality was used, fluorescent tube 10 was that the electrode contact 13 by metal end 12 is inserted in the electrode jack 24 of lamp socket 20, electrically connected and lighted lamp tube body 11 by starter 23 to reach.Yet, because the principle of luminosity of fluorescent tube 10 is to bump with the electronics of electrode effusion and the particle in the fluorescent tube 10, and then send ultraviolet ray and excite the fluorescent material of coating in the fluorescent tube to send white light, the heavy metal element that the fluorescent material that are coated with in its fluorescent tube 10 all contain the tool contaminative usually (for example: mercury), not only be not easy recycling, the easier pollution that causes environment, therefore how to use the mode of more environmental protection to make lighting apparatus, and effectively reduce environmental pollution and become problem and the common recognition that each tame manufacturer desires most ardently solution.
In recent years, flourish along with semiconductor science and technology, light emitting diode (Light EmittingDiode, LED) manufacturing technology also reaches its maturity, present light emitting diode has been enough to use as the light source of illumination, power saving, volume are little because light emitting diode possesses, long service life, stable height, residual optical activity is low and height is lit a lamp characteristic such as replys, therefore, at present institute develops the light emitting diode pipe that to be enough to replace fluorescent tube and more accepts in market, even the trend of replacement conventional bulb or fluorescent tube has been arranged.Yet, because light emitting diode need be welded on the circuit board, so above-mentioned light emitting diode pipe can only provide unilateral illumination, this is little for the fluorescent lamp influence that replacement is arranged on the ceiling, because the fluorescent lamp on the ceiling need not to provide illumination respectively in relative both sides.But, in the time will replacing the fluorescent lamp that is arranged in the double-faced advertising billboard, because need provide illumination respectively, so must use two light emitting diode pipes to replace a fluorescent lamp in relative both sides, so that provide illumination, will cause thus cost is set significantly improves respectively at relative both sides.
Illustrate that as Fig. 2 A Fig. 2 A comprises: sleeve pipe 31, lampshade 32, circuit board 33 and light emitting diode 34 for now having the stereogram of light-emitting diode lamp tube.Because existing light emitting diode pipe need dispose many light emitting diodes 34 simultaneously and could satisfy the requirement of user to brightness, and light emitting diode 34 all is welded on the same one side of circuit board 33, therefore this light emitting diode pipe can only provide the single face illumination, and the illumination of " 360 degree " can't be provided as existing fluorescent lamp, and be applied to need the situation of two-sided illumination, for example: be installed in the double-faced advertising billboard and throw light on, make the general fluorescent lamp of illumination zone of this light emitting diode pipe come poorly.
The front is mentioned, because the light emitting diode pipe only can provide the single face illumination, need can't be applied to the situation of two-sided illumination.Therefore, just there is manufacturer to propose to have the illuminating lamp (please refer to the 12 figure in the TaiWan, China patent announcement number M342471 number) of the two-sided light source of heat abstractor, the structure of this illuminating lamp sees also Fig. 2 B, Fig. 2 B comprises: illuminating lamp 40, heat abstractor 41 and light source 42 for the structural representation of existing double-side illuminating lamp.This illuminating lamp 40 is arranged at the relative both sides of heat abstractor 41 with light source 42, and in order to two-sided illumination to be provided, and the heat energy that is produced by 41 pairs of light sources 42 of heat abstractor dispels the heat.Yet, because this heat abstractor 41 is because of its area of dissipation deficiency, thus can't effectively make this illuminating lamp 40 have good thermolysis, even influence the service life of this illuminating lamp 40.
In sum, background technology has existed the light emitting diode pipe that two-sided illumination can't effectively be provided always and the problem of great heat radiation effect is provided since the midium or long term as can be known, is necessary to propose improved technological means therefore in fact, solves this problem.
Summary of the invention
Because the problem that background technology exists, the present invention discloses a kind of LED lamp device with two-sided illumination then.
The disclosed LED lamp device with two-sided illumination of the present invention comprises: cooling base, LED lighting module and lampshade.Wherein, this cooling base has first and second, and this first formation has first accommodation space of corresponding first guide rail, and this second then forms second accommodation space with corresponding second guide rail; These two LED lighting modules are arranged at respectively in first accommodation space and second accommodation space of this cooling base; These two lampshades are covered on first accommodation space and second accommodation space by this corresponding first guide rail and this corresponding second guide rail respectively, in order to these two lighting modules are covered.
The disclosed LED lamp device of the present invention as above, be that with the difference between the background technology the present invention forms first accommodation space with corresponding first guide rail respectively by the relative both sides at this cooling base, and formation has second accommodation space of corresponding second guide rail, and after these two LED lighting modules are fixedly arranged on this first accommodation space and this second accommodation space respectively, be covered on first accommodation space and second accommodation space of this cooling base more respectively with these two lampshades, in order to these two LED lighting modules are covered, make these two LED lighting modules provide illumination respectively, and have better heat radiating effect relative both sides.
By above-mentioned technological means, the present invention can reach the technology effect of the illumination zone that promotes the LED lamp device.
