Description
Luminous lamp decoration is the daily life indispensable, consumes more electric energy but traditional illuminating source is general, and damages easily.With Christmas lights is example, and its employed illuminating source is to continue to use traditional osram lamp, and the luminous lighting principle of this osram lamp is to utilize Ohm's law, during tungsten filament in electric current is flowed through this bulb, converts the electric energy that is consumed to heat energy, and then produces light.
But osram lamp can produce high temperature between the operating period, so the bulb shell must adopt glass to bear high heat.But the thickness of glass shell is quite thin, easily in use or dismounting when cause the fragmentation of glass shell accidentally because of collision or the application of force.And osram lamp general work electric current is all greater than 50mA, comparatively power consumption.So comparatively ideal luminous lamp decoration must be with following requirement:
(1) lighting angle wants big;
(2) firm shell is arranged and be difficult for damage;
(3) can not produce high temperature between the operating period and influence the service life of relevant decorative components on every side;
(4) consumed power is few, and luminous efficiency is good, to conform with power saving and environmental protection requirement;
(5) outward appearance appearance variation;
(6) low cost.
So just can guarantee security that indoor and outdoor uses, anti-going into property and aesthetic property, become cheap and good-quality lamp decoration.
Light emitting diode (LED) then is a kind of illuminating source that has above-mentioned requirements concurrently, and it not only is used in the usefulness of the display floater of products such as computer, facsimile machine as the message indication, also has been used for the purposes of billboards or decoration.The employed package casing shape of general known light emitting diode mainly contains semicircle sphere, half round post, quadrangular prism shape, turriform etc.Fig. 1 is a known light emitting diode 10; its employed packaged type is a kind of packaging system 11 of semicircle column type; this packaging system 11 is in order to fixing diode crystal particle 12 and support 13; and the light that can protect metal wire 14. this kind packaged types between diode crystal particle 12 and the support 13 LED crystal particle 12 can be launched is made the effect of many light harvesting lines by semi-cylindrical top; as as the same lens with most of light-ray condensing in half-cylindrical top; so; the brightness of experiencing when human eye is faced this light emitting diode 10 is the strongest; watch then brightness promptly to decay to the side more, that is the light that light emitting diode 10 is launched have less visual angle (as shown in Figure 2).The packaged type of these semicolumns has its historical background, former is to wish that LED crystal particle 12 light that produces is focused on the dead ahead as far as possible reaches the purpose of strengthening demonstration, easy speech, the light that LED crystal particle 12 produced just can't be dispersed and cause the shortcoming of visual angle deficiency to the side.So the light emitting diode that will plant packaged type a bit is used as the illuminating source of lamp decoration, does not obviously meet the needs of the wide viewing angle of general luminous lamp decoration.
For overcoming the very narrow shortcoming of diopter when the luminous lamp decoration of light emitting diode, the method that improves was once disclosed in the novel patent of " spheroidal low current self-lighting device ".As shown in Figure 3, Fig. 3 is the diagram that illustrates spheroidal low current self-lighting device 30, this novel patent is modified to spheroidal with the type shape of LED package shell, it also emphasizes to place a self-lighting element 31 (being LED crystal particle) near the circumference of ball packaging system 32, uses light that self-lighting element 31 launches can be in this ball packaging system 32 be launched from all directions via various refractions and reflection effect.The preparation method of this spheroidal low current self-lighting device 30 comprises (1) earlier on support (LEAD FRAME) 34, with the fixing LED crystal particle of elargol; (2) encapsulate above-mentioned LED crystal particle with the transparent light-transmitting materials of height again, the mode of encapsulation can form the ball shape of different-diameter; (3) handle at the desired roughness of package surface.Though this kind ball packaging system 32 can enlarge the visual angle of LED, produces following shortcoming simultaneously:
(1) this device is subject to the design of spherosome, can not do the variation of various different appearance and modelings.
When (2) packaging system is designed to spherical shape, because of relating to release problems, so can't encapsulate (by the encapsulating operation of traditional LED, because of used Resin Flow is very high, so used adhesive filling mould must be one-body molded and the action of branch mould can not be arranged) in the encapsulating mode of traditional LED.Even utilize the mode of general ejection formation, with the method for similar IC encapsulation encapsulating material is injected mould, but cause the disconnected row of metal wire 33 between LED crystal particle and the support 34 easily, and then the problem of influence encapsulation yield rate.
