Abstract
The invention discloses an LED lamp bead. The LED lamp bead comprises an LED chip, a support and a light-permeating layer. The LED chip is installed in the middle of the upper surface of the support, the area except the LED chip on the upper surface of the support is coated with an insulation glue layer, the LED chip is coated with a fluorescent powder glue layer, the light-permeating layer is located outside the fluorescent powder glue layer, the positive electrode and the negative electrode of the LED chip are connected with wires, the insulation glue layer is coated with a reflecting layer, and the fluorescent powder glue layer is in an oval shape. Preferably, triangular conical protrusions are arranged on the surface of the reflecting layer. According to the LED lamp bead, the insulation glue layer is coated with the reflecting layer, light ray reflection is facilitated through the oval fluorescent powder glue layer, and the irradiation area of the LED lamp bead is increased; in addition, the area except the LED chip on the upper surface of the support is coated with the insulation glue layer, and the heat dissipation of the LED lamp bead is facilitated.
Description
Technical field
The present invention relates to LED lighting field, particularly a kind of LED lamp pearl structure.
Background technology
LED light emitting diode is known as the most efficient artificial lighting engineering by the whole world.There is life-span length, low power consumption and other advantages, along with the development of LED technology, the performance of LED light source is also become better and better, in general, whether the work of LED lamp is stable, quality quality, most important with lamp body heat radiation itself, the heat radiation of high-brightness LED lamp in the market, usually adopts natural heat dissipation, and effect is unsatisfactory.The LED light fixture that LED light source is made, is made up of LED, radiator structure, driver, lens, and therefore heat radiation is also a part and parcel, if LED can not finely dispel the heat, its life-span also can be influenced.In addition present LED also deposits the problems such as LED light illumination range is narrower.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of LED lamp pearl is provided, increase irradiated area, improve the heat dispersion of LED light fixture, thereby improve life-span and the performance of LED chip.
For achieving the above object, technical scheme of the present invention is: a kind of LED lamp pearl, comprise LED chip, support, photic zone, middle part, the rack-mount surface of LED chip, rack upper surface other areas except LED chip scribble insulation glue-line, fluorescent material glue-line is coated on LED chip, photic zone is positioned at fluorescent material glue-line outside, and the both positive and negative polarity of LED chip connects wire, insulating barrier outside, scribble one deck reflecting layer, described fluorescent material glue-line be shaped as ellipse.As optimization, there is triangular pyramidal projection on surface, reflecting layer.
LED lamp pearl of the present invention, in insulating barrier outside, scribbles one deck reflecting layer, the fluorescent material glue-line of elliptical shape, contributes to light reflection, increases the irradiated area of LED lamp pearl, in addition rack upper surface other areas except LED chip scribble insulation glue-line, contribute to distributing of LED lamp pearl heat.
Accompanying drawing explanation
Fig. 1 is LED lamp pearl structural representation of the present invention.
The specific embodiment
The invention will be further described for embodiment plan given below; but can not be interpreted as it is limiting the scope of the invention; according to the present invention, content, to nonessential improvement and adjustment more of the present invention, still belongs to protection scope of the present invention to those skilled in the art.
As shown in Figure 1, LED lamp pearl comprises LED chip 1, support 2, photic zone 3, LED chip 1 is arranged on support 2 upper surface middle part, support 2 upper surfaces other areas except LED chip 1 scribble insulation glue-line 4, fluorescent material glue-line 5 is coated on LED chip 1, and photic zone 3 is positioned at fluorescent material glue-line 5 outsides, and the both positive and negative polarity of LED chip 1 connects wire 6, insulation glue-line 4 outsides, scribble one deck reflecting layer 7.Fluorescent material glue-line 5 be shaped as ellipse.
There is triangular pyramidal projection on 7 surfaces, reflecting layer.LED chip 1 can be blue chip, and support 2 can be made of copper, and photic zone 3 can adopt transparent glass or printing opacity glue.LED chip 1 can be connected by crystal-bonding adhesive with support 2.LED lamp pearl of the present invention, in insulating barrier outside, scribbles one deck reflecting layer, contributes to light reflection, increases the irradiated area of LED lamp pearl, and rack upper surface other areas except LED chip scribble insulation glue-line in addition, contribute to distributing of LED lamp pearl heat.
Claims (2)
1. a LED lamp pearl, comprise LED chip, support, photic zone, middle part, the rack-mount surface of described LED chip, rack upper surface other areas except LED chip scribble insulation glue-line, and fluorescent material glue-line is coated on LED chip, and photic zone is positioned at fluorescent material glue-line outside, the both positive and negative polarity of LED chip connects wire, it is characterized in that described insulating barrier outside, scribble one deck reflecting layer, described fluorescent material glue-line be shaped as ellipse.
2. according to the LED lamp pearl described in claim 1, it is characterized in that there is triangular pyramidal projection on surface, described reflecting layer.
