Description
Technical field
The utility model relates to LED field, relates in particular to a kind of vertical LED lamp bar.
Background technology
Existing LED lamp bar, because the power density of LED chip is very high, this just needs the designer of LED chip device and producer to be optimized meter to cooling system at aspects such as structure and materials.
Along with the exploitation gradually of high-power LED chip, also be developed for effectively discharging the hot technology that LED chip produces thereupon, in order more to improve the radiating efficiency of LED chip, normally LED chip is encapsulated on a substrate, and this substrate is made by metal material conventionally, and realize the electrical connection of LED chip and substrate by wire-bonded.
But therefore the poor thermal conductivity of the insulating barrier forming on metal substrate, even if used metal substrate also cannot avoid the problem that thermal conductivity is low.And, also great majority employing PCB wiring board of the wiring board of LED lamp bar at present, it does not have light transmission yet.Cannot accomplish that LED packaging body is omnibearing luminous.
Therefore, if the heat radiation of LED chip cannot normally realize, as a kind of LED chip of semiconductor device, because heat radiation wavelength changes, thereby the emission efficiency that produces yellowing phenomenon or light can reduce, and while at high temperature operation, the life-span of LED encapsulation may shorten, thereby to be improved be the core of encapsulating structure and technique to the structure that the heat that LED chip is produced dispels the heat.
Utility model content
The purpose of this utility model is to provide a kind of vertical LED lamp bar.It can realize the luminous in all directions of LED.
For achieving the above object, the utility model is by the following technical solutions:
A kind of vertical LED lamp bar; it comprises: the glass wiring board and the protector plate for glass that are oppositely arranged; and be arranged on the multiple LED chips between glass wiring board and protector plate for glass; wherein the top of each LED chip is provided with the first electrode; bottom is provided with the second electrode; described the first electrode is connected with the one side of protector plate for glass, and described the second electrode is connected with the one side of glass wiring board, is also enclosed with protective layer on described LED chip.
Preferably, described LED lamp bar also comprises phosphor powder layer, and described phosphor powder layer is located at respectively glass wiring board and protector plate for glass on the face of LED chip.
Preferably, described the first electrode is connected with the one side of glass wiring board by gold thread, described the second electrode by scolder connect, eutectic connect or die bond connect be connected with the one side of glass wiring board.
Preferably, described LED lamp bar also comprises phosphor powder layer, and described phosphor powder layer is located between each LED chip and protective layer.
The utility model adopts above design, by LED chip is directly encapsulated on glass wiring board, relatively original LED chip need first be encapsulated on metal substrate, be encapsulated into again on PCB wiring board, save processing step, provide cost savings, and can accomplish the omnibearing luminous of LED chip, improved the brightness of LED chip; Another glass wiring board has higher heat-resisting and heat-resisting quantity, has extended to a certain extent the useful life of LED lamp bar, and glass wiring board also has better heat dispersion simultaneously.In another the utility model, also can, by directly LED chip being encapsulated on glass wiring board, save original substrate, save material; The first electrode of the present utility model is connected from different glass plates respectively with the second electrode simultaneously, and the heat of LED chip just can distribute to two places by these two electrodes like this, has improved its radiating efficiency.
