Abstract
The utility model relates to a cyan LED (light emitting diode) lamp bead which comprises an aluminum base plate, an LED chip and a positive and negative guide pin, wherein a bowl-shaped groove is arranged in the middle of the aluminum base plate, the LED chip is arranged at the bottom inside the groove and is sealed in the groove by sealing compound, the LED chip is connected with the positive and negative guide pin embedded in the aluminum base plate through gold wires, the LED chip is a blue ray chip, the blue ray chip is sealed in the groove by the sealing compound containing green phosphor, and the sealing compound is silicon gel or epoxy glue gel. The cyan LED lamp bead has the advantages that the green chip is directly replaced by the sealing compound containing the green phosphor, the voltage of products is reduced, production cost is saved, the structure is simple, and processing and manufacture are convenient.
Description
Technical field
The utility model relates to a kind of LED lamp pearl, particularly a kind of cyan LED lamp pearl.
Background technology
Do not have blue or green light LED wafer in the prior art, it mainly mixes by blue light and green wafer, and according to the principle of three primary colours, blue light wafer and green wafer are lighted simultaneously, and blue light source mixes with green light source and sends the cyan light source.Its weak point is: use blue light, green wafer to mix, and product overtension then, the electric leakage ratio is bigger during welding, and tester table cannot detect forward and reverse.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, and a kind of cyan LED lamp pearl is provided.
For achieving the above object, the utility model adopts following technical scheme: cyan LED lamp pearl, comprise aluminium base, LED wafer and both positive and negative polarity guide pin, described aluminium base middle part is provided with the groove of bowl cup-shaped, the LED wafer is arranged on the groove inner bottom part and is encapsulated in the groove by sealing, described LED wafer connects with both positive and negative polarity guide pin in being embedded in aluminium base by spun gold, described LED wafer is the blue light wafer, the sealing of blue light wafer by containing green emitting phosphor is in groove, and described sealing is silica gel or epoxide-resin glue.
The utility model is compared with background technology, has the sealing that has green emitting phosphor and directly substitutes green wafer, can reduce the voltage of product, also can save production cost simultaneously, and simple in structure, processing and fabricating is convenient.

Fig. 2 is the plan structure schematic diagram of cyan LED lamp pearl.
Embodiment
Embodiment 1: with reference to Fig. 1 and 2.Cyan LED lamp pearl, comprise aluminium base 2, LED wafer 3 and both positive and negative polarity guide pin 1, described aluminium base 2 middle parts are provided with the groove of bowl cup-shaped, LED wafer 3 is arranged on the groove inner bottom part and is encapsulated in the groove by sealing 4, described LED wafer 3 connects with both positive and negative polarity guide pin 1 in being embedded in aluminium base 2 by spun gold, described LED wafer 3 is the blue light wafer, and the blue light wafer is encapsulated in the groove by the sealing 4 that contains green emitting phosphor, and described sealing 4 is silica gel or epoxide-resin glue.Wherein, after the blue light wafer is selected, can in sealing, join a certain proportion of green powder according to the pairing wave band of cyan.When if change takes place the cyan wave band, the ratio that only needs suitably to adjust green powder gets final product.Even when change took place blue light wafer wavelength, the ratio that also can suitably adjust green powder was finished the effect of quick pairing, need not to use the blue light of specific dimensions, certain luminance, specific wavelength and green wafer to mix.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection range of the present utility model.
