Description
Technical field
The utility model relates to a kind of double-colored novel C OB integrated optical source, technical field be LED energy conservation and environmental protection light source,
The fields such as video display light source, outdoor lighting.
Background technique
Currently, the double-colored COB light source of tradition, is on the bracket that chip has been welded, by different-colour block box dam
Glue is isolated into individual region, and example coats warm white fluorescent powder in the region of identical warm white colour temperature, in positive white temperature area,
It is coated with just white fluorescent powder.After high temperature, glue curing forms double-colored COB light source.
Double-colored COB light source is driven using two groups of independent circuits, and two kinds of colors i.e. individually power supply is lighted.But it passes
Double-colored COB light source unite to guarantee to synthesize consistency of colour using the positive alternatively distributed design of warm white color and individually light not
When a kind of color, because there is another color block to be distributed between adjacent color block, and there is the partition of box dam glue, itself is not excited
It sends out and shines, cause solid color distribution not concentrated, there is the presence of dark space between color block.
Summary of the invention
The technical issues of the utility model solves, which is that removal is intermediate, does the processing separated with box dam glue, while effectively solving
When solid color is lighted, there are problems that dark space.
It is as follows that the utility model solves the technical solution that above-mentioned technical problem is taken:
A kind of double-colored COB integrated optical source, comprising: bracket (4), and it is provided with luminous zone in the middle part of bracket (4), this shines
The blue chip (3) of blue wavelength is installed, after crossing Reflow Soldering, the complete die bond of blue chip is on bracket, and chip is equal in area
Even distribution；In addition, being provided with red fluorescence powder coating layer (2) on the half surface of the blue chip (3), set on luminous zone
Whole yellow fluorescent powder coating layers (1) are set, the two is mixed by fluorescent powder respectively and solidified through high-temperature baking；Red fluorescence powder coating
Layer (2) is operated alone by power supply, wherein in the case where lighting, while excitated red fluorescent powder and yellow fluorescent powder, so that this
Region where segment chip issues warm white, without the chip of coated red fluorescent powder, excites yellow fluorescent powder, sends out just white
Light.
The utility model is a little:
1. eliminating the link for needing box dam glue to separate in production technology, product cost is saved；
2. using chip surface gluing process, blocking for box dam glue is saved, so that chip light emitting is lighted single without barrier
When colour light emitting, effectively preventing shining has the case where dark space, non-uniform light.
Other features and advantages of the utility model will illustrate in the following description, also, partly from specification
In become apparent, or understood and implementing the utility model.The purpose of this utility model and other advantages can pass through
Structure specifically indicated in the written description, claims, and drawings is achieved and obtained.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawing, so that the above-mentioned advantage of the utility model is more
It is clear.
Fig. 1 is the structural schematic diagram of the double-colored COB integrated optical source of the utility model.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.
The utility model is to have changed production technology, i.e., traditional in the case where original production principle is constant
Dispensing coats in the link of fluorescent powder, improves to some extent.
As shown in Figure 1, a kind of double-colored COB integrated optical source, comprising: bracket (4), and hair is provided in the middle part of bracket (4)
Light area is equipped with the blue chip (3) of blue wavelength in the luminous zone, and after crossing Reflow Soldering, the complete die bond of blue chip is in bracket
On, and chip is uniformly distributed；In addition, the half surface of the blue chip (3) is provided with red fluorescence powder coating layer (2),
Whole yellow fluorescent powder coating layers (1) are set on luminous zone, and the two is mixed by fluorescent powder respectively and solidified through high-temperature baking；It is red
Color fluorescent powder coating layer (2) is operated alone by power supply, wherein in the case where lighting, while excitated red fluorescent powder and yellow
Fluorescent powder, without the chip of coated red fluorescent powder, excites yellow glimmering so that the region where this segment chip issues warm white
Light powder, sends out white light positive.
Specifically, yellow fluorescent powder is filled in whole money luminous zone, that is, the chip of red fluorescence powder is coated with, in the feelings lighted
Under condition, while rouge and powder and bloom are excited, so that the region where this segment chip issues warm white, there is no coated red fluorescence
The chip of powder, value excitation yellow fluorescent powder, sends out white light positive, that is, realizes the effect that positive warm white shines simultaneously.Also, it is driven adjusting
Electric current size, make just white and warm white at the color mixing of different proportion, can be realized in 3000-6500k reference color temperature
Any colour temperature section color.
Specific step is as follows:
1, by bonder, the chip of blue light wavelength is placed on to the chip reserved location of bracket, the i.e. luminous zone of light source,
After crossing Reflow Soldering, the complete die bond of chip is on bracket, and chip is to be uniformly distributed.
2, on a kind of block of colour light emitting of original, cancels the partition processing of box dam glue, fluorescent powder is applied only to chip
Surface after solidification, coats the fluorescent powder of another color, i.e., the fluorescence of two kinds colors through high-temperature baking in positive block luminous zone
Powder is to mix, and is solidified in high-temperature baking.
The utility model is a little:
1. eliminating the link for needing box dam glue to separate in production technology, product cost is saved；
2. using chip surface gluing process, blocking for box dam glue is saved, so that chip light emitting is lighted single without barrier
When colour light emitting, effectively preventing shining has the case where dark space, non-uniform light.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
