Description
Technical field
The utility model provides a kind of flexible LED light source substrate of using in the wide-angle light-emitting lamp of being mainly used in, and belongs to field of semiconductor illumination.
Background technology
As lighting technology of new generation, LED development is very fast, and technology constantly promotes, market scale constantly enlarges, and constantly replaces the traditional lighting light fixture by feat of advantages such as energy-saving and environmental protection, all solid state, long-lives.
Over the past two years, the problem that the space luminescence angle of light fixture exists becomes consumers in general and producer's Focal Point of Common Attention, the space luminescence angle of traditional incandescent lamp and fluorescent lamp can reach more than 300 °, luminous close to the total space, and in the space luminescence angle of product nominal, lamp luminescence is very even, does not have tangible dark space and glare phenomenon.Present LED light fixture, as: the space luminescence angle of light fixtures such as LED bulb lamp, LED candle lamp, LED fluorescent tube is all less, its main cause is: all led light sources all are positioned at same plane, light emission direction is identical, and lampshade only is hemisphere or little dome-type, adopting the luminous angle of light fixture maximum space of this lampshade in theory is 180 °, however since the problem of luminous intensity distribution generally can only reach about 120 °.In order to address this problem, people have carried out the improvement of a lot of aspects, such as using the frosted lampshade, increase frosted by the inner surface at lampshade, make light in lampshade inside through repeatedly the reflection, scattering, improve the purpose at the space luminescence angle of light with realization, adopt this method generally can realize 130 °～160 ° space luminescence angle; Someone further, increase the profile of lampshade, make it to surpass semicircle, further promote the space luminescence angle of light fixture by lampshade, this method also can improve light fixture the space luminescence angle, can reach 160 °～230 °, obviously improve the optical issue that of light fixture, but fundamentally do not address this problem, because all light sources still at grade, when light emits from light source, remain to approximate same direction emission; In order further to improve the space luminescence angle of light fixture, address this problem fully, someone has been configured to each light source in the light fixture on the different planes, the light-emitting area of light fixture is arranged to a plurality of independently light-emitting areas, so just can make different light sources shine different directions respectively, CN101893180 provides a kind of LED candle lamp that adopts this conceptual design, in this candle lamp, some LEDs light sources are welded on the correspondence position of radiator respectively, made it to realize substantially the space luminescence more than 300 °, yet still there are some technical problems in this scheme, mainly contain: owing to there is the carrier radiator as strutting piece and heat sink to exist, each concave edges profile place at radiator, all more or less have a light-baffling phenomena, each profile can block the light that the light source of this profile place one side sends, thereby makes light periodic dark space occur in spatial distributions.
Summary of the invention
To be solved in the utility modelly be: LED light fixture space luminescence angle is less than normal, and there are periodically technical problems such as dark space in the light fixture space luminescence.The utility model provides a kind of flexible LED light source substrate in batch and manufacture method, and the led light source that several separate substrates are made folds or enclosing with substrate in batch, can realize needed light fixture space luminescence demand.Concrete technical scheme is:
A kind of flexible LED light source substrate in batch includes insulating barrier, reflector layer and at least 2 substrates, and the one side of insulating barrier is fixed in the front of described substrate, and substrate leaves the gap each other; The position that insulating barrier is relative with substrate is provided with opening, and the insulating barrier another side is provided with for the line layer that connects chip packing-body; Described line layer and insulating barrier another side are provided with reflector layer.
This led light source can be assemblied in LED lamp inside with substrate in batch, and when it was made led light source, the COB that installs in the substrate in batch (chip on board) quantity of light source can be selected according to the structure of the LED lamp of reality, can be set to 3～6 usually; The material of insulating barrier can adopt conventional materials such as FR4, FR5, and it has certain pliability, makes substrate in batch to bend according to actual conditions, and the light source module after guaranteeing to make can throw light on towards different directions.The arrangement of the COB light source in the substrate in batch arranges according to actual conditions, for example: can be made as single file, also can be set to multiple lines and multiple rows; Steep for common LED lamp, a plurality of COB light sources are arranged by single file get final product, if when needing in the light to use the light source module of multirow, the light source module that both can adopt a plurality of this single files to arrange also can adopt multiple lines and multiple rows to be arranged into whole light source module; The light source module that adopts single file to arrange is better, and it is convenient processing and manufacture not only, when the LED lamp is installed, also is convenient to install.
Be to couple together between with chip packing-body in the effect of the line layer that insulating barrier arranges, connected mode can adopt series, parallel or series-parallel connection.When needing, the also pad that can be connected with line layer the setting of the insulating barrier of substrate in batch, by pad substrate in batch is connected with external circuit, the position of pad does not need special restriction, arrange according to the side circuit situation and to get final product, for example: when adopting the light source module of single file arrangement, can on the substrate with two ends in the module pad be installed.
Because by insulating barrier each substrate is linked to each other between the substrate in batch, it has certain flexibility or bendable folding endurance, it can be bent to given shape, to reach to the purpose of different directions irradiation.Crooked shape can be according to actual needs or the structure of LED lamp set, both can become certain cambered surface, also the light source module can be surrounded cast, with reach to around carry out illumination purposes.
Substrate can adopt aluminium base or ceramic substrate, and the interval between the adjacent substrate is 2～10mm preferably; Above-mentioned reflector layer can adopt conventional welding resistance wet goods.
The utility model also provides a kind of method that is suitable for the substrate in batch of industrialized production, specifically:
A kind of flexible LED light source comprises the steps: with the manufacture method of substrate in batch
S1: be taken to few 2 substrates, described substrate be fixed on the one side of insulating barrier with being spaced from each other, the contacted position of described insulating barrier and substrate is provided with opening;
S2: the another side at insulating barrier is installed line layer and pad;
S3: not pasted reflector layer by the zone of line layer and pad covering on the line layer and on the described insulating barrier another side, obtain flexible LED light source substrate in batch.
When using this substrate in batch to make light source, chip is installed on opening part, the encapsulation of insulating barrier on the substrate in batch, again line layer is connected with chip, get final product.
Technique effect
The flexible LED light source that the utility model provides is mainly used to make the LED light fixture with wide-angle space luminescence with substrate in batch, as the LED candle lamp, the LED bulb lamp, light fixtures such as LED fluorescent lamp, it is big that the LED light fixture that the flexible LED light source that adopts the utility model to provide produces with substrate in batch has the space luminescence angle, space luminescence is even, advantage such as the production of light fixture, manufacturing process are simple.
