Description of the drawings

Fig. 1 is the decomposition diagram for the fluorescent effect more preferably LED light that the utility model embodiment provides.

Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

The same or similar label correspond to the same or similar components in the attached drawing of the present embodiment；In retouching for the utility model In stating, it is to be understood that if it is based on attached drawing to have the orientation or positional relationship of the instructions such as term "upper", "lower", "left", "right" Shown in orientation or positional relationship, be merely for convenience of describing the present invention and simplifying the description, rather than indicate or imply institute The device or element of finger must have a particular orientation, with specific azimuth configuration and operation, therefore position described in attached drawing is closed The term of system only for illustration, should not be understood as the limitation to this patent, for those of ordinary skill in the art and Speech, can understand the concrete meaning of above-mentioned term as the case may be.

The realization of the utility model is described in detail below in conjunction with specific embodiment.

Shown in referring to Fig.1, preferred embodiment is provided for the utility model.

Fluorescent effect provided in this embodiment more preferably LED light, including substrate 1, the substrate 1 is provided with pit 2, described Plating is equipped with silver layer 3 in pit 2, and LED chip 4 is provided on the silver layer 3, and point is covered with one layer of first fluorescence in the LED chip 4 Powder forms the first phosphor powder layer 5, and one layer is provided on first phosphor powder layer 5 and is mixed by the second fluorescent powder and transparent adhesive tape The mixing fluorescent glue 6 of formation.

The fluorescent effect of above-mentioned offer more preferably LED light, by the way that pit 2 is arranged on substrate 1, pit 2 plays protection LED The effect of chip 4, while pit 2 prevents mixing fluorescent glue 6 from overflowing, is plated on pit 2 convenient for the curing molding of mixing fluorescent glue 6 If one layer of silver layer 3, there is silver layer 3 preferable light albedo, the light that LED chip 4 is sent out to pass through the reflection of silver layer 3, carry The light efficiency of high LED light, effect of the light that LED chip 4 is sent out through the first phosphor powder layer 5, forms the fluorescence of particular color, then passes through The effect for crossing mixing fluorescent glue 6, the fluorescent effect for making the light that LED light sends out more preferably, when the first phosphor powder layer 5 fail, mix Fluorescent glue 6 can also continue to function, and improve the service life of LED light, provided great convenience to the user.

Specifically, it is 0.5 antisolvent precipitation powder that mixing fluorescent glue 6 addition, which has mass percent,；Antisolvent precipitation powder is mainly used In LED light source allotment fluorescent powder and prevent fluorescent powder from precipitating, improve encapsulation procedure consistency, be added mass percent be 0.5 Antisolvent precipitation powder, can play prevents fluorescent powder from precipitating, and improves the consistency of encapsulation procedure, while dosage is reasonable, has saved life Produce cost.

Specifically, it is 1 second fluorescent powder that mixing fluorescent glue 6 addition, which has mass percent,；It is glimmering using second After light powder, the LED of its all band can be prepared using the high advantage of certain wave band LED luminous efficiencies, to improve the wave band Luminous efficiency.

The emission wavelength of LED is also difficult to accurately control now, thus can cause the LED of some wavelength that cannot apply When now wasting, such as needing to prepare the LED of 470nm, that may prepare is the LED that range is very wide from 455nm to 480nm, LED of the emission wavelength at both ends can only be disposed or discarded with less expensive price, and use the second fluorescent powder can be by this A little so-called " waste products " are converted to our required colors and are utilized.

After the second fluorescent powder, the photochromic of some LED can become softer or bright-coloured, to adapt to different applications It needs.Certainly, fluorescent powder is most widely applied on LED or in white light field, but due to its special advantage, in colour Also certain application can be obtained in LED.

The second fluorescent powder that mass percent is 1 reduces the second fluorescent powder while realizing preferable fluorescent effect Usage amount, reduce cost.

Specifically, it is 1 diffusant that mixing fluorescent glue 6 addition, which has mass percent,；Diffusant is mainly used for light Diffusion, the light excessively linearization(-sation) of LED itself need centainly to spread, diffusant improves the range of exposures of LED light, meets use The use demand at family.

Specifically, the antisolvent precipitation powder is the silica flour of aerosil；The silica flour of aerosil not only can be to prevent Only fluorescent powder precipitates, while accelerating the curing rate of mixing fluorescent glue 6, bond effect is improved, due to aerosil Grain ruler is small to also increase the leakproofness and barrier properties of mixing fluorescent glue 6.

Specifically, the diffusant is acrylic resin；The light that LED light is sent out can pass through these transparent diffusants, By refraction many times in acrylic resin, then penetrate.In this way, strong light is through superrefraction, it is uniform to disperse.Make light Source becomes area source, expands light-emitting surface, and light is made to become very soft.Light is can to penetrate diffusant sphere simultaneously , so, the loss of light is few, plays even light, the effect of light transmission.

Furthermore the mixing ratio error of the antisolvent precipitation powder, second fluorescent powder and the diffusant is in ± 0.001g； Mixing ratio error is smaller, and the fluorescent effect for mixing fluorescent glue 6 is better.

The mixing fluorescent glue 6 need to pass through evacuation process and handle；Glue, fluorescent powder, diffusant, antisolvent precipitation powder are put into dry Only it is stirred in dry beaker uniformly, the mixing fluorescent glue 6 after stirring evenly carries out vacuumize process, mixes fluorescence in this way Component is not influenced each ingredient of glue 6 in by air, improves the performance and service life of mixing fluorescent glue 6.

In the present embodiment, circuit structure is provided on substrate 1, circuit structure is electrically connected with LED chip 4；It is external in this way Power supply only needs to be electrically connected by circuit structure and LED chip 4, just can realize external power supply to LED chip 4 for electrician Make, LED chip 4 carries out the work that shines.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model Protection domain within.
