Abstract
The utility model relates to an LED light source which mainly solves the problem of fluorescent powder thermal attenuation caused by serious heating during the using process of the prior LED light source. A left metal support and a right metal support form a reflection concave cup by taking a chip as the center, and a cavity is arranged between the refection concave cup and fluorescent glue. The LED light source has the characteristics of low heating value, even luminescence and long service lifetime.
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, cover chip between the fluorescent material, thus so that fluorescent material from the thermal source led chip close to, cause fluorescent material in long-term the use, to be subjected to the degree of heat fade larger, affect stability and the useful life of led light source.
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 exists in use heating serious, and fluorescent material is subject to the problem of heat fade.
The technical solution of the utility model is: a kind of led light source, comprise pedestal, left metallic support, right metallic support, chip and fluorescent glue, described chip is located at base bottom, described fluorescent glue is filled in the pedestal, the anodal conducting terminal of described chip is connected with left metallic support, described chip negative pole conducting terminal is connected with right metallic support, it is characterized in that described left metallic support and right metallic support consist of the reflective concave cup centered by chip, be provided with cavity between described reflective concave cup and the fluorescent glue.
The beneficial effects of the utility model: owing to take such scheme, a kind of led light source of the present utility model, the recessed cup type cavity that arranges, effectively isolate phosphor powder layer and chip, avoid direct thermal contact conductance, the recessed cup sidewall that left metallic support and right metallic support consist of carries out diffuse reflection to the led light source light source, has low, the luminous characteristics that evenly reach long service life of caloric value.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, pedestal 1, right metallic support 2, negative pole conducting terminal 3, chip 4, anodal conducting terminal 5, left metallic support 6, fluorescent glue 7, reflective concave cup 8, cavity 9.
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 pedestal 1, left metallic support 6, right metallic support 2, chip 4 and fluorescent glue 7, described chip 4 is located at pedestal 1 bottom, fluorescent material and adhesive gummed are made fluorescent glue 7, described fluorescent glue 7 is filled in the pedestal 1, and described chip 4 anodal conducting terminals 5 are connected with left metallic support 6, and described chip 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, and the electrical connection of supporting plate line layer, form a series circuit with chip 4, electric current are provided for chip 4, and transmit the chip 4 luminous heats that come out, and effectively prolong the useful life of led light source.
Described left metallic support 6 consists of reflective concave cup 8 with right metallic support 2 centered by chip 4, be provided with cavity 9 between described reflective concave cup 8 and the fluorescent glue 7, effectively avoid fluorescent material and chip 4 direct thermal contact conductances, left metallic support 6 carries out diffuse reflection with reflective concave cup 8 sidewalls that right metallic support 2 consists of to the led light source light source, so that the led light source caloric value is low, luminous evenly.
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.
