Abstract

The utility model provides a kind of red, green, blue and white four colored lights pearl, comprising: cup; Isolated column, is arranged in cup, and cup is divided into the first cup and the second cup by isolated column; Red LED chip, green LED chip and blue-light LED chip, be all arranged in the first cup; First LED chip, is arranged on the second cup, the first LED chip is coated with the fluorescent material for generation of white light.The utility model can utilize the first LED chip to reach the object finding white light, thus make the utility model can send the light of red, green, blue, Bai Si kind color, thus solve in prior art white chip must be used could to make the problem of white light, reduce cost.

Description

Red, green, blue and white four colored lights pearl

Technical field

The utility model relates to LED field, particularly a kind of red, green, blue and white four colored lights pearl.

Background technology

Prior art will realize single LEDs and send out red, green, blue, Bai Si kind colour light emitting simultaneously, and needs employing luminescence is the chip of red, green, blue, Bai Si kind color, and wherein white light must use white chip.

And the production technology of white chip and patent mainly rest in industry giant CREE, OSRAM, Nichia hand, license must be related to as used this type of white chip, and white chip is expensive, usual white chip is higher than common chip price more than 3 times.

Utility model content

The utility model provides the red, green, blue and white four colored lights pearl that a kind of structure is simple, cost is low.

For solving the problem, as an aspect of the present utility model, providing a kind of red, green, blue and white four colored lights pearl, comprising: cup; Isolated column, is arranged in cup, and cup is divided into the first cup and the second cup by isolated column; Red LED chip, green LED chip and blue-light LED chip, be all arranged in the first cup; First LED chip, is arranged on the second cup, the first LED chip is coated with the fluorescent material for generation of white light.

Preferably, fluorescent material is full of the space at the second cup place.

Preferably, the first LED chip is blue-light LED chip.

The utility model can utilize the first LED chip to reach the object finding white light, thus make the utility model can send the light of red, green, blue, Bai Si kind color, thus solve in prior art white chip must be used could to make the problem of white light, reduce cost.

Fig. 2 schematically shows the cutaway view of Fig. 1.

Reference numeral in figure: 1, cup; 2, isolated column; 3, red LED chip; 4, green LED chip; 5, blue-light LED chip; 6, the first LED chip; 7, the first cup; 8, the second cup; 9, fluorescent material.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of red, green, blue and white four colored lights pearl, comprising: cup 1; Isolated column 2, is arranged in cup 1, and cup 1 is divided into the first cup 7 and the second cup 8 by isolated column 2; Red LED chip 3, green LED chip 4 and blue-light LED chip 5, be all arranged in the first cup 7; First LED chip 6, is arranged on the fluorescent material 9 the second cup 8, first LED chip 6 is coated with for generation of white light.Wherein, isolated column 2 can play the effect of blocking fluorescent material diffusion.

Preferably, fluorescent material is full of the space at the second cup 8 place.

Preferably, the first LED chip 6 is blue-light LED chip 5.Certainly, the LED chip of other color of light can also be adopted.

The utility model utilizes isolated column 2 that cup 1 is divided into two independently parts, i.e. the first cup 7 and the second cup 8.Red LED chip 3, green LED chip 4 and blue-light LED chip 5 are positioned at the first cup 7, first LED chip 6 and are then positioned at the second cup 8, and the first LED chip 6 goes back sprayed with fluorescent powder.Like this, the first LED chip 6 just can be utilized to reach the object finding white light, thus make the utility model can send the light of red, green, blue, Bai Si kind color, thus solve in prior art white chip must be used could to make the problem of white light, reduce cost.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
