Abstract
The utility model relates to an LED light source, and mainly aims at solving the problems that the conventional LED light source has low brightness and poor stability while in use, and the whole LED light source fails to work if the chip is burnt. The LED light source comprises a transparent base, a left metal support, a right metal support and a chip assembly, wherein upper fluorescent glue and lower fluorescent glue are respectively bonded on two sides of the chip assembly, the chip assembly, the upper fluorescent glue and the lower fluorescent glue are filled in the transparent base, an anode conductive terminal of the chip assembly is connected with the left metal support, a cathode conductive terminal of the chip assembly is connected with the right metal support, and the chip assembly is composed of at least two chips which are connected in parallel. The LED light source has the advantages of high brightness, good stability and long service life.
Description
Technical field
The utility model relates to a kind of led light source.
Background technology
Along with strengthening gradually of energy-conserving and environment-protective consciousness and reaching its maturity of photoelectric technology, led light source becomes the study hotspot of industry gradually.Existing White LED light source excites yellow fluorescent powder with the blue led chip usually, the blue light that is sent by led chip and the green-yellow light synthesize white light of fluorescent material.In actual production, led chip is arranged at the bottom of pedestal, use the die bond welding, the led chip top arranges one deck fluorescent glue.In the led light source of this structure, take single led chip as light emitting source, the shinny degree of light source is very limited, and in long-term the use, chip burns, and namely causes led light source integral body to lose effectiveness.
The utility model content
In order to overcome deficiency and the defective in the background technology, the utility model provides a kind of led light source, mainly solves existing led light source and has in use low, the poor stability of brightness, when chip burns, namely causes led light source integral body to lose the problem of effectiveness.
The technical solution of the utility model is: a kind of led light source, comprise transparent base, left metallic support, right metallic support and chip assembly, the both sides of described chip assembly are fitted with respectively fluorescent glue and lower fluorescent glue, described chip assembly, upper fluorescent glue and lower fluorescent glue all are filled in the transparent base, the anodal conducting terminal of described chip assembly is connected with left metallic support, described chip assembly negative pole conducting terminal is connected with right metallic support, it is characterized in that described chip assembly is to be no less than two the chip composition that is in parallel.
The beneficial effects of the utility model: owing to take such scheme, led light source of the present utility model, two the chip of being no less than that arranges forms chip assembly, can reach larger brightness of illumination requirement, and when one of them chip damages, other chips are appointed right can playing effectiveness, and have the characteristics of brightness height, good stability and long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure cutaway view of A-A face among Fig. 1.
Among the figure, transparent base 1, right metallic support 2, negative pole conducting terminal 3, chip assembly 4, anodal conducting terminal 5, left metallic support 6, upper fluorescent glue 7, lower fluorescent glue 8.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
Shown in figure, a kind of led light source, comprise transparent base 1, left metallic support 6, right metallic support 2 and chip assembly 4, fluorescent material and adhesive gummed are made fluorescent glue 7, the both sides of described chip assembly 4 are fitted with respectively fluorescent glue 7 and lower fluorescent glue 8, described chip assembly 4, upper fluorescent glue 7 and lower fluorescent glue 8 all are filled in the transparent base 1, described chip assembly 4 anodal conducting terminals 5 are connected with left metallic support 6, and described chip assembly 4 negative pole conducting terminals 3 are connected with right metallic support 2.Left metallic support 6 and right metallic support 2 extend pedestal 1, be electrically connected with the supporting plate line layer, form a series circuit with chip assembly 4, electric current is provided for chip assembly 4, and transmit the chip assembly 4 luminous heats that come out, effectively prolong the useful life of led light source.
Described chip assembly 4 can be a plurality of chips composition that is in parallel, as preferred version, present embodiment is that two chips are in parallel and form described chip assembly 4, can reach larger brightness of illumination requirement, and when one of them chip damages, other chips are appointed right can playing effectiveness, and have the characteristics of brightness height, good stability and long service life.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
