Description
Technical field
The utility model relates to LED technology field, particularly relates to a kind of 360 ° of emitting led light sources of novel specular removal.
Background technology
The osram lamp of artificial light sources from is to state-of-the art electricity-saving lamp, and their illumination mode is to all the winds luminous all the time, is all the illuminating product of 360 degree of luminescences.The luminous characteristics of traditional LED lamp tool has direction one to property, only to project a light beam to a fixing direction.Clearly traditional LED is applied to room lighting towards the photocurrent versus light intensity that a specific direction sends out light beam and can be very restricted, and can not come into huge numbers of families like a cork.For making LED illumination product can be widely used in the fields such as indoor general lighting, commercial lighting, office lighting, fill up the deficiency of traditional LED illumination, studying 360 degree of beam angle space luminescence LED product becomes the problem being badly in need of solving.
Also there is the LED product of 360 degree of luminescences in the market, if the patent No. is 201120148195.6, the Chinese utility model patent of the high efficiency LED of a kind of LED chip 4 of title π bright dipping, its structure is for install LED chip on the transparent substrate, and coating or the mixing of encapsulation one deck are by the transparent dielectric layer of fluorescent material, reach the effect of 360 degree of luminescences.But the patented product exists several shortcoming: 1. send blue light by chip, excite yellow fluorescent material to reconcile into white light, and do not do blue light spilling defensive measure, there is the problem that blue light overflows, from spectrum analysis, except infrared ray, ultraviolet, the chance that blue light hinders eye is larger.The pole forceful rays of short-term can cause the damage of cornea, retina especially macula area, show as that shouting pain photophobia is shed tears, eyesight drops to blind suddenly.2. utilize jelly fixing metal sheet to carry out the connection of realizing circuit at substrate two ends, by the restriction of glue high-temperature behavior, there is certain defect, on the one hand in filament LED process, easily to be heated or the impact of pressure causes metal and LED-baseplate obscission, on the other hand make in light fixture and use procedure in application end, the impact of equally easy received heat, cause coming off of sheet metal and substrate.
Summary of the invention
The utility model mainly solves current 360 degree emitting ledly to be existed blue light and overflows and the problem that is easily separated with substrate of sheet metal, provides and a kind ofly prevents blue light spilling, 360 ° of emitting led light sources of novel specular removal that sheet metal is connected firmly.
The utility model solves the technical scheme that its technical problem adopts: a kind of 360 ° of emitting led light sources of novel specular removal, comprise transparency carrier, substrate is provided with some LED wafer, be connected by gold thread between LED wafer, be packaged with dielectric layer respectively at the positive back side of substrate, the backside surface of described substrate is regularly arranged uneven structure.The utility model carries out roughening treatment to the backside surface of substrate, form rough structure, achieve the multiple reflections of light in transparency carrier by regularly arranged rough structure, reach the lifting of the extraction efficiency of substrate exterior light, effectively prevent the blue light spilling that LED wafer sends.Substrate back is after roughening treatment on the other hand, the luminous efficiency in alligatoring face is improved, and while raising Total Product light efficiency, the light efficiency in alligatoring face improves, reduce the luminance difference with face, LED wafer place, thus improve the hot spot uniformity of light source.
As a kind of preferred version of such scheme, the dielectric layer surface being arranged on substrate front side amass be less than be arranged on substrate back dielectric layer surface amass.After the blue chip luminescence of substrate front side, because substrate exists certain thickness, and substrate is transparency carrier, substrate edges has some blue light and overflows, and by the setting of this programme, dielectric layer surface because of substrate back amasss the surface area being greater than substrate front side hypothallus, effectively prevent the spilling of blue light further.
As a kind of preferred version of such scheme, be respectively arranged with sheet metal at the two ends of described substrate, described sheet metal is provided with Ka Zui, substrate is embedded in card mouth.This programme wraps substrate by sheet metal Ka Zui, substantially increase the bonding dynamics between sheet metal and substrate, solving sheet metal in traditional LED lamp silk adopts jelly to fix, in LED support, assembling light fixture process and later stage use procedure, sheet metal is easy to the problem departed from from substrate, improves product yield and quality.
As a kind of preferred version of such scheme, side, portion, described card gonys is provided with card article along edge, described base ends on the surface correspondence be provided with draw-in groove, the both sides of Ka Zui are respectively arranged with discount, substrate on both sides, end respectively correspondence be provided with catching groove, sheet metal is arranged on after on substrate, and card article is entrapped in draw-in groove, and discount is fastened in catching groove.Sheet metal is not easily movable and move up and down, and what it is such that sheet metal can be more fastening is wrapped on substrate, not easily departs from, improves product yield and quality.
As a kind of preferred version of such scheme, in described dielectric layer, be evenly distributed with spread powder.Also comprise spread powder in the dielectric layer, effectively prevent the spilling of blue light further, ensure that the volume production feasibility of product.
As a kind of preferred version of such scheme, concavo-convexly on the surface of described substrate both sides be formed with one deck extension layer, described extension layer comprises some projections and some grooves, described projection and the groove arranged adjacent that interlocks becomes several rows, and row and row between projection and groove also interlaced, described projection structure wide at the top and narrow at the bottom, projection and groove are close to mutually, make groove form the large structure of the little inner chamber of opening.This diffusion layer makes source light to carry out multiple reflections and refraction, and make luminescence more even, diffusion layer too increases the contact area of substrate side surfaces and air in addition, adds the radiating effect of substrate, effectively improves the making power of LED.
As a kind of preferred version of such scheme, described projection is located lower position, and the head of projection is more past to be upwarped.According to the angle of source light, rationally arrange projection head position, the projection head making to be located side lower is more past to be upwarped, and makes light more through projection, can form better reflection and refraction, make luminescence more even like this.
The utility model has the advantages that: 1. the backside surface of pair substrate carries out roughening treatment, form rough structure, the multiple reflections of light in transparency carrier is achieved by regularly arranged rough structure, reach the lifting of the extraction efficiency of substrate exterior light, effectively prevent the blue light spilling that LED wafer sends.2. the luminous efficiency in alligatoring face is improved, and while raising Total Product light efficiency, the light efficiency in alligatoring face improves, and reduces the luminance difference with face, LED wafer place, thus improves the hot spot uniformity of light source.3. sheet metal Ka Zui wraps substrate, substantially increases the bonding dynamics between sheet metal and substrate.
