Abstract
The utility model relates to the technical field of LED lamps, in particular to a low-cost pink LED. A pink fluorescent powder layer is coated on the inner surface of an alcove of a cathode of the LED, and a blue LED chip is mounted in the alcove. The pink fluorescent powder layer is the mixture of pink fluorescent powder and fluorescent glue. After the structure is adopted, the utility model resolves the problem that the conventional pink LED needs to made of high-cost semiconductor material, the low-cost blue LED chip is used, the light is pink after being reflected by the pink fluorescent powder layer below, and thereby the cost is greatly reduced, which is favorable for the popularization and application of the pink LED.
Description
Technical field:
The utility model relates to LED lamp technical field, refers in particular to a kind of novel cheaply powder red-light LED.
Background technology:
As everyone knows, the core of LED is the wafer that P type semiconductor and N type semiconductor are formed, and semi-conductive material is well imagined the influence of LED.The color of the light that the corresponding LED of different semi-conducting materials produces is also different.Usually, the semi-conducting material cost of blue-ray LED is lower, and therefore the semi-conducting material cost height of other colors LED is unfavorable for popularization and the application of other colors LED.
The utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, and a kind of simple in structure, novel powder red-light LED that cost is low is provided.
The utility model realizes that the technical scheme that its purpose adopts is: the negative pole alcove inner surface of this LED is coated with one deck pink phosphor powder layer, and blue-light LED chip is installed in the alcove.
Described pink phosphor powder layer is the mixture of pink fluorescent material and fluorescent glue.
When making the utility model powder red-light LED, earlier pink fluorescent material and fluorescent glue are mixed, be coated on negative pole alcove inner surface then, blue-light LED chip is installed then, get final product with epoxy encapsulation at last.
After the utility model adopts said structure, solved the problem that traditional powder red-light LED must use expensive semi-conducting material, use blue-light LED chip cheaply, after the pink phosphor powder layer reflection of below, can present pink light, greatly reduce cost, help the promotion and application of powder red-light LED.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
As shown in Figure 1, the utility model powder red-light LED comprises epoxy encapsulation solid 1 and positive and negative electrode pin 2,3, the coated one deck of the inner surface of the alcove 30 of negative pole pin 3 pink phosphor powder layer 4 wherein, this pink phosphor powder layer 4 is coated after evenly mixing by pink fluorescent material and fluorescent glue, very thin thickness.Blue-light LED chip 5 be installed in pink phosphor powder layer 4 the top, therefore, when blue-ray LED was luminous, pink phosphor powder layer 4 reflection through the below externally just presented pink light.
In sum, the utility model is simple in structure, and cost is low, helps the development and use of powder red-light LED.
Claims (1)
1. novel powder red-light LED is characterized in that: the negative pole alcove inner surface of this LED is coated with one deck pink phosphor powder layer, and blue-light LED chip is installed in the alcove.
