Abstract
The utility model discloses an LED (Light-Emitting Diode) lamp bead, which comprises an LED chip, a substrate and a light-passing layer, wherein the substrate is groove-shaped; the LED chip is arranged on the middle part of the upper surface of the substrate; a fluorescent powder adhesive layer is coated on the LED chip; the light-passing layer is positioned outside the fluorescent powder adhesive layer; an included angle between the outer edge of the light-passing layer and a plane where the LED chip is positioned is 20 degrees; a gap between the light-passing layer and the substrate is filled with an insulating adhesive layer; the substrate is wrapped outside the insulating adhesive layer; a contact surface between the insulating adhesive layer and the light-passing layer is coated with a reflecting layer; the anode and cathode of the LED chip are connected with leads; the substrate can be made of copper; the light-passing layer can be made of transparent silica gel. According to the LED lamp bead, the included angle between the outer edge of the light-passing layer and the plane where the LED chip is positioned is 20 degrees, the gap between the light-passing layer and the substrate is filled with the insulating adhesive layer, the contact surface between the insulating adhesive layer and the light-passing layer is coated with the reflecting layer, and the groove-shaped substrate is wrapped outside the insulating adhesive layer, so that dissipation of heat emitted by the LED lamp bead is facilitated.
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, 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, it is outside that photic zone is positioned at fluorescent material glue-line, 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, it is outside that described substrate is wrapped in insulation glue-line, 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.
The utility model LED lamp pearl, 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, it is outside that groove type substrate is wrapped in insulation glue-line, contributes 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, 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.
Claims (3)
1. a LED lamp pearl, comprise LED chip, substrate, photic zone, the groove type that is shaped as that it is characterized in that described substrate, LED chip is arranged on substrate upper surface middle part, fluorescent material glue-line is coated on LED chip, it is outside that photic zone is positioned at fluorescent material glue-line, 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, it is outside that described substrate is wrapped in insulation glue-line, insulation glue-line and photic zone contact-making surface scribble reflecting layer, and the both positive and negative polarity of LED chip connects wire.
