Abstract

The utility model discloses a lens applied to a light-emitting diode (LED) lamp, which comprises a lens body in which an LED light source containing space is arranged. The LED light source containing space is provided with an incident lateral face and an incident bottom face, wherein the incident lateral face and the incident bottom face enable light to enter the lens body. A rare-earth fluorescent powder coating or a quantum dot fluorescent powder coating is respectively coated on the incident lateral face and the incident bottom face of a single LED light source containing space or a combination type LED light source containing space, and a blue light LED is arranged in the LED light source containing space so as to achieve various white light. Due to the fact the blue light LED is free of problems of patents, even an LED made in China is utilized, a whole white-light lamp is not at risks of while-light patents. Additionally, if the quantum dot fluorescent powder coating is utilized, high-efficiency white light can be converted into high-light-efficiency warm white light as well.

Description

A kind of lens that are used for the LED light fixture
Technical field
The utility model relates to a kind of lens, particularly a kind of lens that are used for the LED light fixture.
Background technology
LED is as directional light sources, and power savings advantages is very obvious in the directional lighting field, has obtained using widely.The warm colour light that directional lighting major requirement colour rendering is higher; Concerning LED; Warm colour light colour rendering can both reach more than 80, but its light efficiency is than the low 20%-30% of cool colour light, and present cold white light volume production level has reached 130lm/W; Have only 100lm/W, price even more expensive but warm colour light is the highest than the cool colour light of Gao Liang.
Warm colour LED is coated on yellow (or yellow adds redness) fluorescent material on the blue light wafer, obtains warm white through blue-light excited yellow (or yellow adds redness) fluorescent material.On the one hand, the light efficiency of the LED of warm colour not high (than the low 20%-30% of cool colour light) like this; On the other hand, all there is patent barrier in the encapsulation of LED like this.
The utility model content
The utility model has overcome above-mentioned deficiency of the prior art; A kind of lens of the LED of being used for light fixture are provided; These lens are coated with rare earth fluorescent material or quantum dot fluorescence powder on the incident bottom surface, incident side at the led light source accommodation space; When lighting in the led light source accommodation space that blue-ray LED is placed on lens, just can obtain various white lights.
The technical scheme of the utility model is achieved in that
A kind of lens that are used for the LED light fixture; Comprise lens body; In lens body, be provided with the led light source accommodation space, this led light source accommodation space has makes light enter into incident side, the incident bottom surface of lens body, on incident side and incident bottom surface, is coated with the fluorescent RE powder coating.
A kind of lens that are used for the LED light fixture; Comprise lens body; In lens body, be provided with the led light source accommodation space, this led light source accommodation space has makes light enter into incident side, the incident bottom surface of lens body, on incident side and incident bottom surface, is coated with quantum dot fluorescence powder coating.
Adopted the principle and the beneficial effect of the utility model of technique scheme to be:
The utility model is with coated with rare earth fluorescent material or quantum dot fluorescence powder on the incident bottom surface of the led light source accommodation space of single or many compound lens, the incident side, and blue-ray LED is placed in the led light source accommodation space, just can obtain various white lights.Because there is not the problem of patent in blue-ray LED, so even use homemade LED, whole white LED lamp does not have the risk of white light patent yet.And,, also can realize high efficiency white light is changed into high light efficiency warm white if use quantum dot (Quantum Dot) fluorescent material.

Fig. 3 is the cutaway view of lens among the utility model embodiment 2.
The specific embodiment
The specific embodiment of the utility model is following:
Embodiment 1: a kind of lens that are used for the LED light fixture; Like Fig. 1, shown in Figure 2; Comprise lens body 1; In lens body 1, be provided with led light source accommodation space 2, this led light source accommodation space 2 has makes light enter into incident side 3, the incident bottom surface 4 of lens body 1, on incident side 3 and incident bottom surface 4, is coated with fluorescent RE powder coating 5.
Embodiment 2: a kind of lens that are used for the LED light fixture; As shown in Figure 3; Comprise lens body 1; In lens body 1, be provided with led light source accommodation space 2, this led light source accommodation space 2 has makes light enter into incident side 3, the incident bottom surface 4 of lens body 1, on incident side 3 and incident bottom surface 4, is coated with quantum dot fluorescence powder coating 6.
