Detailed description of the invention

Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:

Fig. 1 is the structural schematic diagram of one embodiment of the utility model.

Specific embodiment

Below with reference to drawings and examples the utility model is described further, but this reality should not be limited with this With novel protection scope.

As shown in Fig. 1, the utility model provides a kind of LED lamp comprising light emitting module 1, light conversion body 2, reflection Outer cover 3 and optical component 5.

Wherein, light emitting module 1 include outer enclosure body and multiple luminescence unit 1-1 inside outer enclosure body, 1-2,1-3.Above-mentioned luminescence unit is LED luminescence unit, and above-mentioned luminescence unit is white light LEDs, blue-ray LED, green light LED and feux rouges The one at least within of LED.Multiple luminescence unit arranged in parallel.

Light conversion body 2 is provided at the lower surface of light emitting module 1, which can be high light transmittance resin, example Such as PET, the mixing of PVC, EVA etc. and optical wavelength conversion particles；Either in high light transmittance resin (such as PET, PVC, EVA Deng) deposit optical wavelength conversion material film layer on the surface of lamina material.

The light conversion body 2 can be used for being converted to some blue light the light of yellow wavelengths, to supplement LED luminescence unit The deficiency of middle yellow light.The light conversion body 2 is mounted in the independent cavity 4 of 3 top of reflective outer shroud.

The lower half portion of the reflective outer shroud 3 is reflection chamber, deposited highly reflecting films on the inner wall of the reflection chamber, such as The overlapping body of metal film either SiN/SiO2 film layer.The reflection chamber of the reflective outer shroud has the shape of rotary table, i.e., towards light Line, which projects direction, has the diameter being gradually increased.

In the lower opening of the reflective outer shroud 3, it is provided with optical component 5.The optical component 5 is (excellent with certain thickness Be selected as 5-20mm) circular sheet-like structures, the protrusions of one cone of points 5 setting of the center portion thereof remain as flat around protrusion Shape structure.The material of the optical component 5 can be high light transmittance resin (such as PET, PVC, EVA etc.).The circle of the tapered protrusion Highly reflecting films are also provided in cone sidewall surfaces, which is the overlapping body of metal film either SiN/SiO2 film layer.Light Line is only capable of projecting from the flat structure around protrusion, can be reflected if light is irradiated to raised position.

The protrusion is preferably dimensioned to be diameter in 1-5cm, is highly 2-3cm.

The reflective outer shroud 3 and the combination of optical component 5 form a closed reflection cavity.In use, light is from hair Optical module 1 is shot down, and certain optical transition is carried out across light conversion body 2, so as to adjust irradiant colour temperature and coloration, Light continues downward part of propagation light and is reflected in the reflecting wall of reflection chamber, and some light is reflected in convex portion, Some light is possible to carry out multiple reflections, and final light has certain inclination from the transparent flat structure around protrusion Angle projects.

By LED lamp provided by the utility model, the light-emitting uniformity of LED lamp can be improved.

According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality The mode of applying is changed and is modified.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right Some modifications and changes of the utility model should also be as falling into the protection scope of the claims of the present utility model.In addition, to the greatest extent It is used some specific terms in pipe this specification, these terms are merely for convenience of description, not to the utility model Constitute any restrictions.
