Abstract
A light-emitting diode (LED) white light bulb comprises a bulb shell and an LED luminophor arranged inside the bulb shell, and is characterized in that the LED luminophor is a cylindrical body formed by directly packaging chips on other base boards in a seal mode utilizing board integrated encapsulation technology, a heat radiating through hole penetrating axially is formed inside the cylindrical body, and a cylindrical heat radiator is arranged inside the heat radiating through hole. The LED white light bulb can emit lights with an angel of 360 degrees in a large range and a wide angle, the heat radiator is arranged in the seal mode, the working temperature of LED to a greatest extent, good heat radiating effect can be maintained, and the temperature of an working environment of the LED white light bulb is maintained to be constant.
Description
Technical field
This practicality relates to the LED bulb, especially led chip is packaged into the LED white light bulb of the bulb of incandescent lamp contour structures.
Background technology
In recent years, development along with the LED technology, the various performances of LED lamp for illumination are greatly improved, and more because the LED light fixture has long, the series of advantages such as luminous efficiency is high, do not have ultra-violet radiation, good energy-conserving effect of life-span, become the development trend of following light source.
At present, the use of LED lamp is more and more universal, and the LED lamp of prior art is because the encapsulating structure reason, substantially is to do into strips with tabular, and single direction is luminous, can only realize luminous in the certain limit can't realizing that 360 ° of gamuts are luminous.And under the volume, light-emitting 3 D is soft etc., and the aspect does not replace traditional incandescent lamp fully.
The photoelectric transformation efficiency of LED only has 15 ~ 25%, namely only has 15 ~ 25% electric energy to be converted to luminous energy, and remaining electric energy nearly all becomes heat energy, and led chip PN junction temperature is raise, and light efficiency and life-span reduce, and have a strong impact on the performance of LED.
Existing LED bulb does not have radiator structure mostly, and minority neither be the radiator structure that certain bulb is made separately with radiator structure, and is simple in structure, radiating effect is poor.
Therefore, how can make 360 ° of led light source realizations luminous, keep simultaneously good heat radiation, become a large research and development problem of LED industry.
Summary of the invention
The utility model has proposed to utilize the incandescent lamp shell for above problem especially, 360 ° of luminous white light LEDs bulbs.And have good heat dispersion, reduce the bulb operating temperature.
The technical solution of the utility model is: a kind of LED white light bulb, comprise bulb shell and be encapsulated in the interior LED illuminator of bulb shell, it is characterized in that, described LED illuminator is to utilize the column that the integration packaging technology directly consists of chip package on the plate to the substrate on it, there is a heat radiation through hole that axially connects described column inside, and is fitted with pole-shaped radiator in the heat radiation through hole.
Described column is multiedge cylinder, is packaged with led chip on each cylinder, and described led chip uniform array is distributed on each cylinder.
Best implementation is that polygon prism is hexahedron or octahedron.
Described LED illuminator comprises column that the multiaspect substrate consists of, is encapsulated in the led chip on the substrate, and the gold thread, the covering that connect led chip and substrate are encapsulated in the packaging plastic that is mixed with yellow fluorescent powder outside the chip.
The beneficial effects of the utility model: can with the LED lamp reach incandescent lamp on a large scale, 360 ° of wide-angle irradiate light comprehensively, and be packaged with radiator, reduce LED operating temperature keeps great heat radiation effect, it is constant to keep LED lamp operating ambient temperature.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
A kind of LED white light bulb, comprise bulb shell 1 and the LED illuminator 2 that is encapsulated in the bulb shell 1, it is characterized in that, described LED illuminator 2 is to utilize integration packaging technology on the plate directly led chip 6 to be encapsulated into the column that the substrate 3 on it consists of, there is a heat radiation through hole 4 that axially connects described column inside, and is fitted with pole-shaped radiator 5 in heat radiation through hole 4.Described radiator 5 is for being placed on the tubular body with heat radiation through hole 4 in substrate 3 cavitys.
Described column is multiedge cylinder, can be hexahedron or octahedron, if there is larger structure also can be treated to more multiaspect regular polygon, is packaged with led chip 6 on each cylinder, and described led chip 6 uniform arrays are distributed on each cylinder.The LED illuminator that so consists of is encapsulated in the shell of bulb, consists of to all around without the 360 ° of luminous LED bulb structures in dead angle.
Described LED illuminator 2 comprises column that the multiaspect substrate consists of, is encapsulated in the led chip 6 on the substrate, the gold thread 7, led chip 6, the covering that connect led chip 6 and substrate 3 are encapsulated in the packaging plastic that is mixed with yellow fluorescent powder 8 outside the chip, have insulating cement 9 within the packaging plastic and between the led chip, outside packaging plastic 8 also capping a reflector 10 that strengthens the light irradiating angle.Described gold thread connects the circuit of leading led chip and substrate, and gold thread one end is even led chip electrode 11, one ends and even led electrode of substrate 12.
This LED bulb can with the LED lamp reach incandescent lamp on a large scale, 360 ° of wide-angle irradiate light comprehensively, and be packaged with radiator, reduce LED operating temperature keeps great heat radiation effect, it is constant to keep LED lamp operating ambient temperature.
