Description
Technical field
[0001] the utility model relates to a kind of LED light source of high-luminous-efficiency, belongs to LED light source technical field.
Background technology
[0002] owing to having, luminous efficiency is high, little power consumption, the feature such as pollution-free for LED device, is just being widely used in the fields such as TV backlight, advertisement sign, picture and text showing, decorative lighting.Along with improving constantly of luminous efficiency, the reduction of chip, cost such as raw material such as encapsulation glue, support etc., LED device has started to enter the room lighting such as commercial lighting, lighting of home field.In order to reduce the packaging cost of LED device, reduce LED number of devices required when applying, improve the application flexibility of LED device, often adopt plurality of LEDs chip to be positioned in single led support and carry out integration packaging, and in order to meet the cooling requirements of integration packaging form, the good material of LED support many employings thermal conductivity is as baseplate material.
The COB light source of a kind of finished product assembling of the prior art, it comprises substrate and a pair positive and negative metal electrode, and substrate is planar structure, and positive and negative metal electrode is flatly attached on substrate, substrate is provided with die bond, bonding wire, box dam and encapsulating region.The COB light source adopting above-mentioned LED support to make in industry, uses the nontransparent silica gel box dam of milky, encapsulating processing procedure finished product, but, because tradition uses box dam glue to be nontransparent silica gel, lighting angle is 120 °, and lighting angle has certain limitation, thus has influence on the light extraction efficiency of light source.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of LED light source of high-luminous-efficiency.
The LED light source of the utility model high-luminous-efficiency, it comprises substrate 1, positive electrode 2, negative electrode 3, packaging plastic 4, mixing box dam glue 5 and solid welding zone 6, the middle part of substrate 1 is solid welding zone 6, the left and right side of substrate 1 is respectively provided with a pair positive electrode 2 and negative electrode 3, Gu the outer ledge of welding zone 6 is provided with a circle mixing box dam glue 5, Gu the top of welding zone 6 adopts packaging plastic 4 to encapsulate.
As preferably, described mixing box dam glue 5 mixes for silica gel and yellow, The Scarlet Letter or green emitting phosphor, and the viscosity of silica gel is 10000-20000 Pas.
As preferably, insulate between the upper left positive electrode of described substrate 1 and upper right negative electrode and isolate, insulation isolation between lower-left positive electrode and bottom right negative electrode.
The beneficial effects of the utility model: it can overcome the drawback of prior art, novel in structural design is reasonable, substrate arranges this transparent silica gel of enclosing and adds phosphor process, increase light source rising angle, improving extraction efficiency, and its technique is simple, suitable for large-scale promotion.
