Description
Technical field
The utility model relates to a kind of LED, particularly relates to the LED of a kind of both sides luminescence.
Background technology
In prior art, usual employing iron wire or other ribbon materials with certain rigidity construct the word that some play advertisement or propaganda function, the framework of pattern or symbol, then LED is laid along iron wire or ribbon material, thus required word can be constructed with the light that LED sends, pattern or symbol, but make people all can see these words from positive and negative to allow, pattern or symbol, usual need arrange two groups of LED mutually arranged dorsad, the work causing LED to be installed thus is very complicated, and cost of manufacture is also difficult to decline.
Summary of the invention
The utility model is intended to solve above-mentioned mentioned technical problem, provides a kind of structure simple, easy for installation, with low cost and can the LED of both sides luminescence.
The utility model is realized by following technical scheme:
The LED of a kind of both sides luminescence, comprise the LED light source of strip and the transparent gum cover of parcel LED light source, LED light source comprises flexible PCB and is arranged at the LED chip on flexible PCB, the outer rim of described transparent gum cover is also provided with translucent colloid and light tight colloid, wherein, described translucent colloid is arranged at the both sides of LED chip light emission direction, and light tight colloid is arranged at the front of LED chip light emission direction.
Preferably, described light tight colloid is also arranged at the rear of LED chip light emission direction.
Preferably, described translucent colloid is also arranged between transparent gum cover and light tight colloid, translucent colloid is provided with and holds and fix the groove of light tight colloid.
Preferably, described translucent colloid is arranged around transparent adhesive tape cover.
Preferably, described light tight colloid is provided with respectively toward the light-reflecting portion that the both sides of LED chip light emission direction tilt towards the side of LED chip.
Preferably, described light tight colloid, the thickness of its cross section is thinning gradually toward both sides from centre.
Preferably, described light tight colloid is made up of color plastic.
Preferably, the jacket wall of described transparent gum cover is provided with the power line of powering to LED light source.
Beneficial effect is: compared with prior art, by the front of the light emission direction in LED chip, light tight colloid is set, and translucent colloid is set in the both sides of the light emission direction of LED chip, it is luminous while that light can being carried out from the both sides of LED, to take structure word without the need to re-using two groups of LED of the prior art thus, pattern or symbol, people also can from these words, the both forward and reverse directions of pattern or symbol carries out viewing and admiring or read in earnest these information become by Luminant structure, and owing to adopting translucent colloid to make the soft nature of light, discomfort can not be caused to glasses, and owing to decreasing the use amount of LED, thus reduce production cost and make the installment work of LED become simple.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the cross sectional representation of LED of the present utility model.
Detailed description of the invention
The LED 1 of a kind of both sides luminescence as shown in Figure 1, comprise the LED light source of strip and the transparent gum cover 2 of parcel LED light source, transparent gum cover 2 is for being fixed LED light source.The LED chip 4 that LED light source comprises flexible PCB 3 and is arranged on flexible PCB 3.In order to power to LED light source, also being provided with two power lines 21 in LED 1, correspondingly, two can being arranged for holding the string holes of power line 21 on the jacket wall of transparent gum cover 2, contact to prevent between power line 21 with flexible PCB 3 incorrect, avoid short circuit to occur.For making the compact overall structure of LED 1, two string holes can be symmetricly set in the both sides of LED light source respectively.
The outer rim of transparent gum cover 2 is provided with translucent colloid 5 and light tight colloid 6.Translucent colloid 5 is arranged at the both sides of LED chip 4 light emission direction, and light tight colloid 6 is arranged at the front of LED chip 4 light emission direction.
Light tight colloid 6 is arranged at the front of LED chip 4, light can be prevented from the front of LED chip 4 light emission direction directly to outer injection.In order to the rear preventing light to be reflected to the light emission direction of LED chip 4, even if flexible PCB 3 has blocked most light, but still have a small amount of light from this direction toward the injection of LED 1 outside, therefore the rear of LED chip 4 light emission direction also can arrange light tight colloid 6, thus the light that LED chip 4 is sent only outwards can penetrate from the both sides of LED 1.
Translucent colloid 5 is arranged at the both sides of LED chip 4 light emission direction, the light that LED chip 4 can be sent carries out diffuse reflection in translucent colloid 5, also be just equivalent to make translucent colloid 5 become the soft illuminator of light, the light avoiding LED chip 4 to send is directly to outer injection, being provided with like this is beneficial to people and appreciates the moulding be configured to by LED 1, and can not cause discomfort to the eyes of people.
Translucent colloid 5 also can be arranged between transparent gum cover 2 and light tight colloid 6, to strengthen irreflexive effect, reduces light decay.Preferably, also translucent colloid 5 can be arranged around transparent gum cover 2, translucent colloid 5 is illuminated by irreflexive mode by the light sent to make LED chip 4.
Translucent colloid 5 can be arranged and hold and fix the groove 51 of light tight colloid 6, make the outer rim of LED 1 neat, be convenient to carry out installations with the attaching parts of outside fixing.Translucent colloid 5 can select silica gel to make.
Light tight colloid 6 can be arranged respectively toward the light-reflecting portion 61 that the both sides of LED chip 4 light emission direction tilt towards the side of LED chip 4.Be specially, the thickness of the cross section of light tight colloid 6 is thinning gradually toward both sides from centre.Dead ahead due to the light emission direction of LED chip 4 is provided with light tight colloid 6, thus can cause light decay to a certain extent, after arranging light-reflecting portion 61, by the both sides of the light reflection of directive light-reflecting portion 61 to LED chip 4 light emission direction, thus can reduce light decay.Light tight colloid 6 can be made up of color plastic, with the effect making LED 1 have decoration too when not luminous.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, all do not depart from the utility model spirit and scope any amendment or equivalently to replace, it all should be encompassed in the scope of technical solutions of the utility model.
