Abstract

A white light LED (light-emitting diode) lamp changed from a blue light LED (light-emitting diode) lamp through a fluorescent powder coated sheet comprises a blue light LED light source (1), a reflector (2), a radiator (3), a mixed-light cavity (4) and a fluorescent powder coated sheet (5). The blue light LED light source (1) is fixed on the radiator (3), and is covered by the mixed-light cavity (4), the mixed-light cavity (4) is fixed on the radiator (3) through screws, the fluorescent powder sheet (5) is clamped above the mixed-light cavity (4) and the reflector (2), and the mixed-light cavity (4) ,the fluorescent powder coated sheet (5) and the reflector (2) are fixed together through a face ring (6). The fluorescent powder coated sheet is far away from an LED core, so that pyrogen radiation is avoided and service life of the LED lamp can be prolonged.

Description

A kind of blue-ray LED is converted to the LED light fixture of white light by the fluorescent material smear

Technical field

The utility model relates to the LED lamp, and particularly a kind of blue-ray LED is converted to the LED light fixture of white light by the fluorescent material smear.

Background technology

In order to obtain White LED light source, traditional method is directly to be coated with the fluorescent material synthesize white light on light emitting diode, and the thickness of fluorescent material is uncontrollable on the one hand, and the colour temperature deviation is bigger; On the other hand, need change light fixture simultaneously when changing different-colour, cause the wasting of resources, simultaneously, fluorescent material produces problems such as light decay because of the easy loss of influence that is subjected to the thermal source radiation for a long time.

The fluorescent material smear refers to the composite of Merlon (PC) and fluorescent material, and wherein fluorescent material is uniformly coated on the optical grade PC sheet, and the rough surface micro-structural of inner surface not only makes phosphor powder layer have the very high light extraction efficiency that has, and can guarantee the light projector uniformity.The definition of remote fluorescence powder smear is that fluorescent material is made form of film with away from led chip, thereby realize better illumination performance, have better colourity uniformity, lower fluorescent material and colloid temperature, higher light-source brightness, more uniform illuminating effect and more comfortable light projector refusal dazzle.

The utility model content

For overcoming the shortcomings and deficiencies of traditional method, the utility model proposes a kind of blue-ray LED is converted to white light by the fluorescent material smear LED light fixture.

The technical scheme that the utility model adopts is:

A kind of blue-ray LED is converted to the LED light fixture of white light by the fluorescent material smear, comprise blue-ray LED light source, reflection shield and radiator, described blue-ray LED light source is fixed on the radiator, also comprise mixed light chamber and fluorescent material smear, described mixed light chamber covers the blue-ray LED light source, is screwed on radiator; Described fluorescent material smear is clipped on mixed light chamber and the reflection shield, and mixed light chamber, fluorescent material smear and reflection shield three are fixed together by a face ring.

Preferably, described blue-ray LED light source is blue-light LED chip.

Further preferred, the light wavelength scope that described blue-light LED chip sends is 450nm-500nm.

Concrete, described fluorescent material smear is the optical grade PC(Merlon that scribbles yellow fluorescent powder) sheet.

Necessary, comprise that also shell covers reflection shield, fluorescent material smear and mixed light chamber, is fixed on the radiator.

Compared with prior art, the obtained beneficial effect of the utility model has:

1 blue-ray LED described in the utility model is converted to the LED light fixture of white light by the fluorescent material smear, the fluorescent material smear that adopts, fluorescent coating thickness is accurately control easily, the colour temperature deviation is little, change different fluorescent material smears, just can realize the conversion between the colour temperatures such as 2700K, 3000K, 4000K and 5000K;

2 blue-ray LEDs described in the utility model are converted to the LED light fixture of white light by the fluorescent material smear, and the fluorescent material smear has solved the influence of pyrogen radiation away from led chip, can effectively prolong the LED lamp life.

Fig. 2 is blue-ray LED described in the utility model is converted to the LED light fixture of white light by the fluorescent material smear structure explosive view.

The specific embodiment

For making things convenient for those skilled in the art to understand technology contents of the present utility model, below in conjunction with drawings and Examples the utility model is described in further detail.

As illustrated in fig. 1 and 2, the blue-ray LED that the utility model discloses is converted to the LED light fixture of white light by the fluorescent material smear, comprise blue-ray LED light source 1, reflection shield 2 and radiator 3, described blue-ray LED light source 1 is fixed on the radiator 3, also comprise mixed light chamber 4 and fluorescent material smear 5, described mixed light chamber 4 covers blue-ray LED light source 1, is screwed on radiator 3; Described fluorescent material smear 5 is clipped on mixed light chamber 4 and the reflection shield 2, and mixed light chamber 4, fluorescent material smear 5 are fixed together by a face ring 6 with reflection shield 2 threes.The utility model also comprises shell 7 in addition, covers mixed light chamber 4, fluorescent material smear 5 and reflection shield 2, is fixed on the radiator 3.

In the specific implementation, described blue-ray LED light source 1 adopts blue-light LED chip, and the light wavelength scope that described blue-light LED chip sends is controlled at 450nm-500nm, the blue light that sends

Full illumination is in the mixed light chamber, and the light of LED all passes the yellow fluorescent powder smear, and the activated phosphor smear converts white light to and penetrate and to go, and has finished the process that is converted to white light by indigo plant.By changing the thickness of fluorescent material smear, can realize that colour temperature is adjusted to the 2700K(warm white), the 4000K(white light) and the cold white light of 5300K() etc., colour rendering index is adjusted to CRI70, CRI80, CRI90 etc., chromaticity distortion can be controlled within 1 color tolerance difference, and lamp life can reach 50000 hours.The utility model can provide the illuminator of low dazzle, and has higher system effectiveness.In concrete use, the fluorescent material smear that only need change different-thickness just can change indexes such as the colour temperature of light fixture, colour developing, convenient different customer groups' different demands.

Above-described embodiment only is wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
