Description
(1) technical field
The utility model belongs to technical field of LED illumination, is specifically related to a kind of omnidirectional luminous LED lamp silk for automatic spot.
(2) background technology
LED has the advantages such as specular removal, low power consuming, long-life, environmental protection, is optimal conventional light source substitute.As new generation of green light source and lighting engineering, LED is developed rapidly at global illuminating industry in recent years, and product relates to the fields such as backlight, signal lamp, Landscape Lighting, normal domestic illumination.
People have achieved very large breakthrough at LED light source in making now, and most specular removal is more than 250Lm/W, and existing portioned product puts goods on the market.But at present LED illumination lamp in cost of manufacture and product stability in alternative conventional light source advantage remarkable not enough, and its luminous efficiency is less than the half of theoretical value, need further raising.People generally set about the luminous efficiency improving light fixture from the following aspect: one is start with from the improvement of the quality of chip own and configuration aspects, and the space that this respect can improve is comparatively large, but the time that the needs that make a breakthrough are longer, require also higher to the raw and auxiliary material of chip; Two is increase reflecting layer to increase the outgoing chance of light by lamp interior, and then increase amount of light, although reflecting layer can make amount of light increase, but due to blocking of chip package support itself, the light that chip active layer sends to orientation substrate can only penetrate above support, and rising angle and efficiency all can not get good performance.For the encapsulation of employing transparent rack, filament formats or light source are in the packaged type of higher position in lamp housing, and the rising angle of light fixture is comparatively large, and luminous efficiency is higher.The utility model outward appearance is very thin, attractive in appearance, closely similar with traditional tungsten filament, also can obtain the accreditation of many clients.
Due to market craving for filament shape product, cause filament product tight market present situation, the technique of traditional manual spot welding filament all cannot meet the requirement of production in enormous quantities on quality stability or in production capacity.Therefore, many producers start the equipment researching and developing automatic spot one after another, this equipment requirement filament towards unanimously so that spot weld operation, and filament does not in the market have the ability of automatic Identification for direction, the requirement of this automatic spot to filament walking direction therefore can't be adapted to.The utility model mainly provides a kind of filament that automatic spot welding equipment can be coordinated to realize automatic spot.
(
three) summary of the invention
The purpose of this utility model is for the deficiency in above-mentioned background technology, take sapphire as printing opacity heat-conducting substrate for technical field of LED illumination provides a kind of, on the two ends metal electrode guide-lighting heat conduction support of drawing, the automation of encapsulation process can be realized, ad hoc structure simultaneously on extraction electrode makes filament can be applied to the equipment of automatic spot, to improve the omnidirectional luminous LED lamp silk for automatic spot of encapsulation and whole lamp production efficiency.
The purpose of this utility model is achieved in that it comprises LED support and LED chip, LED support is provided with the sapphire 2 of metal layer as guide-lighting heat-conducting substrate by transparent, two ends, additional two extraction electrodes 1 of being drawn by guide-lighting heat-conducting substrate two ends metal layer form, extraction electrode is welded with metal layer by scolding tin, LED chip is fixed on LED support, be interconnected by its both positive and negative polarity by gold thread, the surface of LED support and LED chip is coated with the mixture of silica gel and fluorescent material.
The utility model also has some technical characteristics like this:
1,the metal layer of described LED support is gold or silver or molybdenum or manganese.
,described extraction electrode shape is strip, and be provided with bending structure more nearby at its distance sapphire support, this bending structure, for hanging filament on automatic spot welding equipment, to determine to hang orientation, carries out automatic spot operation.The metal that extraction electrode adopts can be copper or iron or steel, and overlay coating adopts gold-plated or silver-colored or copper or tin or nickel.
,described LED chip adopts blue light or ruddiness or green glow chip.
,described silica gel is phenyl class or methyl class silica gel.
,described fluorescent material is nitride-based rouge and powder, YAG class bloom and green powder.
The beneficial effects of the utility model are: in the utility model, using sapphire as printing opacity heat-conducting substrate, can fully play the characteristic that LED chip six is luminous, improve the luminous efficiency of LED product, suspended structure special on extraction electrode is conducive to the operation of automatic spot welding equipment.Because the mechanical property of sapphire itself is better, intensity is higher, not easily occurs the situation that substrate ruptures improving the yield of encapsulation in encapsulation process.In encapsulation process, be connected on metal layer with gold thread between chip and electrode, because the relative extraction electrode of metal layer will be stablized a lot, therefore the bad phenomenon such as sealing-off can not occur in Long-Time Service situation.The situation that the utility model adopts the collocation of rouge and powder, bloom and green powder to use, colour rendering index can be stabilized in more than 80, be a kind of light source in the pink of condition.After packaging is accomplished, in the process making whole lamp, the bending structure on extraction electrode can be used for automatic spot welding equipment hangs, and greatly improves efficiency and the yield of spot welding, reduces production cost.

Fig. 3 is concrete embodiment schematic diagram.
(5) detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Composition graphs 1, the present embodiment comprises LED support and LED chip, LED support is provided with the sapphire 2 of metal layer as guide-lighting heat-conducting substrate by transparent, two ends, additional two extraction electrodes 1 of being drawn by guide-lighting heat-conducting substrate two ends metal layer form, extraction electrode is welded with metal layer by scolding tin, LED chip is fixed on LED support, is interconnected by its both positive and negative polarity by gold thread, and the surface of LED support and LED chip is coated with the mixture of silica gel and fluorescent material.Extraction electrode shape is strip, is provided with bending structure more nearby at its distance sapphire support.
Composition graphs 3, the purposes of the present embodiment is applied in bulb lamp, is connected by the extraction electrode at LED silk two ends with the mode of the wire on the stem stem in bulb with electric resistance welding, forms some strings structure also (for 2 filaments series connection in Fig. 3).
Omnibearing luminous LED bulb in the present embodiment, can ensure 360 ° of full angle luminescences, lampshade adopts traditional glass material, because the visible light permeability of glass itself is good, can promote the overall brightness of bulb.Meanwhile, owing to using the collocation of the green powder of reddish yellow in filament, its colour rendering is better, and can reach more than 80, be the light source that bulb becomes more healthy.
