Description
Technical field
The present invention relates to the luminous lighting field, particularly luminous lighting equipment technical field specifically is meant a kind of luminous lamp body collector lens structure and relevant lighting device.
Background technology
Along with the continuous progress of human civilization and the continuous development of science and technology, lighting device is widely known by the people already.Generally speaking, this type lighting device comprises housing and the luminous component that is arranged in the said housing.
Along with development of technology; LED can provide enough luminous energy to be used for lighting use; In order to reduce the energy resource consumption of illumination, reduce emission of carbon-dioxide, for promoting constantly advancing of alternative source of light market; With led light source replacement incandescent lamp and Halogen lamp LED has been trend of the times, and the consumer is needed to be that lower energy consumption and longer service life, better quality products at good values are exported, had simultaneously to the light quantity that can reach incandescent lamp or Halogen lamp LED.Though there have been many different LED products releasing on the market, wherein too in costliness, and properties of product do not produce a desired effect great majority concerning ordinary consumer.
According to optical principle, light is easy to reflected and reach spotlight effect by biconvex lens, and reduces the thickness of lens as far as possible in order to obtain same spotlight effect, can adopt Fresnel Lenses to replace conventional biconvex lens.
Fresnel Lenses (Fresnel lens); Claim Fresnel lens again; Be a kind of lens of being invented by French physicist Augustine letter Fresnel, the design of these lens was applied to beacon originally, and this design can be built more wide-aperture lens; Be characterized in that focal length is short, and than the material usage of general lens still less, weight and volume be littler.Compare with early stage lens, Fresnel Lenses is thinner, therefore can reflect more light to form the higher collimated light beam of brightness, even make the beacon distance quite far still can see.

Reduce the distance between Fresnel Lenses and the lamp, the aperture angle of the luminous point that emits is increased continuously.This has just produced the light path of dispersing, and is also referred to as floodlight (flood).
But this light is as having light tailoring defect of insufficient, and especially in gathering spot position (spot position), this is mainly due in this case, gathers and has only in the spot position due to very little relatively space angle scope covered by Fresnel Lenses.
Simultaneously, the light that conventional Fresnel Lenses itself can not play different colours carries out the effect that scattering mixes, and therefore can't be applicable to the various occasions that particular requirement is arranged for light source and luminous beam.
Therefore, the optically focused problem of whole lamp is technical bottleneck always, simultaneously, how to make and a kind ofly can the anaclasis of color of the same race be gone out specific beam pattern and economical and practical lighting device, and be puzzlement people's common problem all the time.Though the technology of LED own is progressive to some extent; Can send the light of various different colours; But how to utilize a kind of simple lens arrangement can light be carried out abundant scattering mixing, reduction manufacturing cost and product complexity, energy-conserving and environment-protective, be pendulum problem demanding prompt solution in face of people always.
