Abstract
The utility model discloses a fluorescent plate. An annular ring is arranged between two light-transmitting bodies that are opposite to each other up and down; a fluorescent rubber layer is arranged between the inner side of the annular ring and the two light-transmitting bodies; and a waterproof layer is formed between the two light-transmitting bodies and the outer lateral edge of the annular ring. The fluorescent plate is located on an LED chip, and the color temperature of the LED chip can be stabilized by transmitting the fluorescent plate.
Description
Technical field
The utility model is about a kind of fluorescent plate, is used to be arranged on the fluorescent plate on the led chip especially in regard to a kind of.
Background technology
Existing white light emitting diode assembly forms a fluorescent glue on a led chip, wherein fluorescent glue is the mixture of fluorescent material and colloid, and the material by fluorescent material in the led chip emission wavelength cooperation fluorescent glue can produce white light; For example cover a yellow fluorescent glue on the blue-light LED chip, the blue light that is sent by led chip can produce white light source through fluorescent glue.
There is following defective in existing white light emitting diode assembly:
1. because of fluorescent glue is coated on the led chip, when led chip was luminous, the heat of its generation accumulated in the fluorescent glue and is difficult for shedding, and therefore makes the poor radiation of led chip, causes the luminous efficiency of led chip to reduce.
2. after curing, do not have a solid shape because of fluorescent glue, it is unequal that the light source that led chip is sent penetrates the path length of fluorescent glue, therefore causes led chip to see through light source color temperature that fluorescent glue produces deviation to some extent.
3. because of led chip combines the structure that is integrally formed with fluorescent glue, if led chip damages, perhaps form impurity in the fluorescent glue, must whole white light emitting diode assembly be scrapped, fluorescent glue and led chip be recycling separately all, causes cost allowance.
4. because of fluorescent glue exposes in the air, so fluorescent glue makes the fluorescent glue deterioration easily by the aqueous vapor influence.
The utility model content
Therefore; The main purpose of the utility model provides a kind of fluorescent plate; Be used to be arranged on led chip; And can improve the led chip poor heat radiation, and avoid the irregularly shaped led chip that causes of fluorescent glue to see through fluorescent glue generation colour temperature deviation and led chip and the existing technological deficiency of fluorescent glue integrative-structure.
For achieving the above object, the technological means that the utility model adopted is to make this fluorescent plate include:
Two printing opacity lamellar bodies are up and down and are oppositely arranged;
One ring is arranged between these two printing opacity lamellar bodies, and forms an accommodation space between this ring inboard and these two printing opacity lamellar bodies;
One fluorescence glue-line is formed in this accommodation space; And
One watertight composition, ring is located at the lateral border of these two printing opacity lamellar bodies and this ring.
The fluorescent plate of the utility model supplies to be arranged on the led chip to carry out mixed light, therefore the utlity model has following effect:
1. when fluorescent plate is arranged on the led chip,, therefore the heat of the luminous generation of led chip more can effectively be shed, promote the luminous efficiency of led chip because of fluorescent plate is not to be coated on the led chip.
2. in the fluorescent plate of the utility model, because of fluorescence glue-line position between these two printing opacity lamellar bodies and ring, make the thickness of fluorescence glue-line comparatively average, so the light that led chip sends is more consistent through the path length of fluorescence glue-line, so can improves the colour temperature deviation.
3. be member independent of each other because of fluorescent plate and led chip, when one of them damages when fluorescent plate and led chip, can change separately wherein that a member get final product, make the recyclable utilization again of fluorescent plate and led chip; And through selecting for use of fluorescent material in the fluorescence glue-line, the luminous wavelength of collocation led chip, the white light source of can arranging in pairs or groups out, thus can effectively reduce cost.
4. be arranged on these two the printing opacity lamellar bodies and the ring outside by marine glue, effectively intercept aqueous vapor and get into the fluorescence glue-line, guarantee the quality of fluorescence glue-line.

Embodiment
The preferred embodiment of following conjunction with figs. and the utility model, further setting forth the utility model is to reach the technological means that predetermined utility model purpose is taked.
Please refer to shown in Figure 1, the preferred embodiment of the utility model, the preferred embodiment includes two printing opacity lamellar bodies 10, a ring 11, a fluorescence glue-line 12 and a watertight composition 13.
These two printing opacity lamellar bodies 10 are up and down and are oppositely arranged, and this two printing opacities lamellar body 10 can be the member that glass is processed.
This ring 11 has the heatproof effect, and this ring 11 is arranged between these two printing opacity lamellar bodies 10, and forms an accommodation space between these ring 11 inboards and these two printing opacity lamellar bodies 10.
This fluorescence glue-line 12 is formed in this accommodation space, and this fluorescence glue-line 12 is the member that evenly mixes shape of transparent adhesive tape and fluorescent material.
These watertight composition 13 rings are located at the lateral border of these two printing opacity lamellar bodies 10 and this ring 11, avoid aqueous vapor to infiltrate to this fluorescence glue-line 12.
Please refer to shown in Figure 2; The fluorescent plate 1 of the utility model is used to be arranged on a led chip 20, and this led chip 20 comprises more than one light emitting source 21, thereby can send optical wavelength according to light emitting source 21; Cooperate selecting for use of fluorescence glue-line 12 interior fluorescent material materials, can produce white light source.
Because of the fluorescent plate of the utility model is a plate body independently, can supply to be arranged on the led chip, can make led chip send the light source of various colour temperatures through the fluorescent plate of the utility model according to the composition of the wavelength-modulated fluorescent material of light source that led chip sends; In addition; Because of this fluorescence glue-line 12 is formed in these two printing opacity lamellar bodies 10 and these ring 11 formed accommodation spaces; Make the consistency of thickness of this fluorescence glue-line 12, make the refraction effect of the light transmission fluorescent plate that led chip sends more consistent, to reach the effect of stable color temperature.
The above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Though the utility model discloses as above with preferred embodiment; Yet be not that any those skilled in the art is in the scope that does not break away from the utility model technical scheme in order to qualification the utility model; Should utilize the technology contents of above-mentioned announcement to make a little change or be modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
