Abstract
The invention discloses an LED lamp bead. The LED lamp bead comprises an LED chip, a substrate and a light transmission layer, wherein the substrate is in a groove shape; the LED chip is installed in the middle of the upper surface of the substrate and coated with a fluorescent powder glue layer; the light transmission layer is located outside the fluorescent powder glue layer; the included angle between the outer edge of the light transmission layer and the plane where the LED chip is located is 20 degrees; the gap between the light transmission layer and the substrate is filled with an insulation glue layer; the substrate wraps the insulation glue layer; the contact faces of the insulation glue layer and the light transmission layer are coated with reflection layers; the positive electrode and the negative electrode of the LED chip are connected with a wire; the substrate can be made of copper, and the light transmission layer can be made of transparent silica gel. According to the LED lamp bead, the included angle between the outer edge of the light transmission layer and the plane where the LED chip is located is 20 degrees, the gap between the light transmission layer and the substrate is filled with the insulation glue layer, the contact faces of the insulation glue layer and the light transmission layer are coated with the reflection layers, and the groove-shaped substrate wraps the insulation glue layer, so that 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, substrate, photic zone, described substrate be shaped as groove type, LED chip is arranged on substrate upper surface middle part, fluorescent material glue-line is coated on LED chip, photic zone is positioned at fluorescent material glue-line outside, photic zone outward flange is 20 degree with angle between the face of LED chip place, gap-fill between photic zone and substrate has insulation glue-line, described substrate is wrapped in insulation glue-line outside, insulation glue-line and photic zone contact-making surface scribble reflecting layer, the both positive and negative polarity of LED chip connects wire.Substrate can be made of copper.Photic zone can adopt transparent silica gel to make.
LED lamp pearl of the present invention, photic zone external margin is 20 degree with angle between the face of chip place, gap-fill between photic zone and substrate has insulation glue-line, insulation glue-line and photic zone contact-making surface scribble reflecting layer, contribute to light reflection, increase the irradiated area of LED lamp pearl, groove type substrate is wrapped in insulation glue-line outside, contributes 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, comprise LED chip 1, substrate 2, photic zone 3, substrate 2 be shaped as groove type, LED chip 1 is arranged on substrate 2 upper surface middle part, fluorescent material glue-line 4 is coated on LED chip 1, photic zone 3 is positioned at fluorescent material glue-line 4 outsides, photic zone 3 outward flanges with angle between LED chip 1 place face are, 20 degree, the gap-fill between photic zone 3 and substrate 2 has insulation glue-line 5, and substrate 2 is wrapped in insulation glue-line 5 outsides, insulation glue-line 5 and photic zone 3 contact-making surfaces scribble reflecting layer 6, and the both positive and negative polarity of LED chip 1 connects wire 7.LED chip 1 can be blue chip, and substrate 2 can be made of copper.Photic zone 3 can adopt transparent silica gel to make.LED chip 1 can be connected by crystal-bonding adhesive with substrate 2.
