Abstract
The utility model relates to the field of the illumination of a light emitting diode (LED), in particular to a light-source lamp of an LED white light emitting diode. Fluorescent particles are arranged on a lamp body of a groove, the distribution density of the fluorescent particles is gradually decreased from the upper part of the groove to the bottom of the groove, and the sizes of the fluorescent particles are gradually decreased from the upper part of the groove to the bottom of the groove, so that the mixing of light emitted by an LED chip and complementary color light generated by the fluorescent particles excitated by the LED chip is more uniform; the influence of heat on the fluorescent particles is small, and the service life is long; and the surface of transparent resin is in the shape of a spherical surface, which can enhance the brightness of light transmittance.
Description
[technical field]
The utility model relates to the LED lighting field, specifically refers to a kind of LED day-light diode light-source lamp.
[background technology]
LED (Lighting Emitting Diode) is a light-emitting diode, it is fixedly luminescent device of a kind of semiconductor, it is to utilize the solid semiconductor chip as luminescent material, in semiconductor, emit superfluous energy and cause photo emissions by charge carrier generation load, directly send the light of white or other colors, the LED lighting utilizes LED as light emitting source exactly.Under the background of current global shortage of energy, energy-conservation LED causes the sight that people pay close attention to.
At present, existing white light-emitting diodes primary structure comprises led chip and lamp body, lamp body is provided with groove, led chip is positioned at bottom portion of groove, be filled with light-transmissive resin in the groove, be provided with fluorescent material in the light-transmissive resin, the fluorescent material major part concentrates near the bottom portion of groove led chip, the luminous back of led chip fluorescence excitation material can not fully mix, and " macula lutea " phenomenon can occur; Because the fluorescent material major part concentrates near the bottom portion of groove led chip, fluorescent material is heated for a long time and brightness decay can occur, influences the brightness and the color and luster of whole LED recently simultaneously.。
[utility model content]
The utility model purpose is to solve the above problems, and a kind of a kind of LED day-light diode light-source lamp of simple in structure, dependable performance is provided.
LED day-light diode light-source lamp of the present utility model, comprise led chip and lamp body, lamp body offers groove, led chip is positioned at bottom portion of groove, and it is trapezoidal that the side section of described groove is concavity, is filled with light-transmissive resin in its groove, and the part that light-transmissive resin exposes groove surfaces is spherical shape, be provided with fluorescent grain in the light-transmissive resin, the distribution density of fluorescent grain reduces to bottom portion of groove gradually from the groove top, and the size of fluorescent grain reduces to bottom portion of groove gradually from the groove top.
Preferably, the lamp body bottom also is provided with metal pins, and metal pins is connected with the led chip bottom.
The utility model LED day-light diode light-source lamp, on the lamp body of groove, be provided with fluorescent grain, the distribution density of described fluorescent grain reduces to bottom portion of groove gradually from the groove top, the size of fluorescent grain reduces to bottom portion of groove gradually from the groove top, and the light that led chip is sent produces complementary coloured light with its fluorescence excitation particle and mixes more evenly; Fluorescent grain is influenced by heat little, long service life; The surface of light-transmissive resin is the brightness that spherical shape can improve printing opacity.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Join shown in Figure 1, the utility model comprises led chip 1 and lamp body 2, lamp body 2 offers groove 3, it is trapezoidal that the side section of described groove 3 is concavity, the side of groove 3 can be used as reflecting surface 31 and carries out the light reflection, led chip 1 is positioned at groove 3 bottoms, be filled with light-transmissive resin 4 in the groove 3, and the part that light-transmissive resin 4 exposes groove 3 surfaces is spherical shape, light-transmissive resin 4 inside are provided with fluorescent grain 5, the distribution density of fluorescent grain 5 reduces to groove 3 bottoms gradually from groove 3 tops, and the size of fluorescent grain 5 reduces to groove 3 bottoms gradually from groove 3 tops.The light that led chip 1 is sent produces complementary coloured light with its fluorescence excitation particle 5 and mixes more evenly, and life of product is longer.
Described led chip 1 is blue-ray LED or purple LED; Fluorescent grain 5 is YAG fluorescent grain or TAG fluorescent grain or RGB three primary colors fluorescent grain.
In addition, lamp body 2 bottoms also are provided with metal pins 6, and metal pins 6 is connected with led chip 1 bottom.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
