Abstract
The utility model provides an LED (Light-Emitting Diode) lamp bead which comprises an LED chip, a bracket and a light-transmitting layer, wherein the LED chip is arranged at the middle of the upper surface of the bracket; the upper surface of the bracket, except for the LED chip, is coated with an insulation rubber layer; a phosphor powder rubber layer is coated on the LED chip; the light-transmitting layer is positioned at the exterior of the phosphor powder rubber layer; positive and negative electrodes of the LED chip are connected with wires; the exterior of the insulation rubber layer is coated with a reflecting layer; the phosphor powder rubber layer is elliptical. As optimization, the surface of the reflecting layer is provided with a bulge which is in the shape of a triangle pyramid shape. According to the novel LED lamp bead, one reflecting layer is coated on the exterior of the insulation rubber layer, and the elliptical phosphor powder rubber layer is beneficial to light reflection, so that the illumination area of the LED lamp bead is increased; in addition, the upper surface, except for the LED chip, of the bracket is coated with the insulation rubber layer, thereby being beneficial to the heat dissipation of the LED lamp bead.
Description
Technical field
The utility model 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, development along with 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 comprised 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 purpose of this utility model is for the deficiencies in the prior art, and a kind of LED lamp pearl is provided, and increases irradiated area, improves the heat dispersion of LED light fixture, thereby improves life-span and the performance of LED chip.
For achieving the above object, the technical solution of the utility model 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, it is outside that photic zone is positioned at fluorescent material glue-line, and the both positive and negative polarity of LED chip connects wire, insulation glue-line top, 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.
The utility model LED lamp pearl, on insulation glue-line top, 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 the utility model LED lamp pearl structural representation.
The specific embodiment
The utility model is described in further detail for embodiment plan given below; but can not be interpreted as it is the restriction to the utility model protection domain; those skilled in the art to nonessential improvement and adjustment more of the present utility model, still belong to protection domain of the present utility model according to the utility model content.
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.
The utility model LED lamp pearl, on insulation glue-line top, 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.
