Description
Technical field
The present invention relates to a kind of lens for omnidirectional lighting device.In addition, the invention still further relates to a kind of omnidirectional lighting device of the lens with the above-mentioned type, and a kind of remodeling lamp.
Background technology
Have the advantages such as life-span length, energy-saving and environmental protection, anti-vibration due to LED light source, therefore, LED light source can be being applied in field widely.Along with the development of manufacturing technology, the more and more lower and light efficiency of the cost of LED has also obtained increase.Solid luminescent (SSL) replaces traditional light-emitting device has become a kind of trend.
The Energy Star standard of the U.S. has proposed certain requirement for omnidirectional's SSL alternative lamp.In the region of 0-135 degree, in the difference between light intensity and the average light intensity in the region of 0-135 degree at any angle not higher than 20%.Luminous flux in the region of 135-180 degree should account for total luminous flux at least 5%.Measurement result within being 45 degree and 90 vertical planes of spending with initial plane should be identical.Most LED light intensity distributions be lambert's type but not uniformity, therefore, secondary optical design is absolutely necessary.For SSL alternative lamp, in order to meet these requirements, conventionally need to design optical module and realize the reallocation of light.
In prior art, there is the scheme of the light source reallocation of multiple acquisition LED lamp.The first scheme is to optimize LED array; First scheme is to utilize reflector to distribute for light.
In field of illuminating device, omnidirectional lighting device can be realized large-area illuminating effect, therefore has larger application prospect.In existing omnidirectional lighting device, a class lighting device has the three-dimensional light source, for example LED chip array that are set directly at cell-shell central authorities, and this light source with cylindricality or dish type array arrangement can throw light in the circumferential direction of 360 degree.The light that light source sends directly penetrates through cell-shell, realizes thus simple omnidirectional lighting effect.This omnidirectional lighting device is for example disclosed by EP2180234A1 and WO 2009/091562 A2.But in the time that the one or more light sources in above-mentioned array of source damage, just cannot realize again omnidirectional lighting effect.In this lighting device, need to install multiple light sources, and respectively by these light sources and circuit board electrical connection.Therefore this lighting device need to consume a large amount of electric energy, and correspondingly produces too much heat.In order to strengthen the radiating effect to column array of source, radiator, for example multiple cooling fins for example can be set in the circumferential exterior surface of column array of source, this is for example disclosed in WO 2010/058325A1.But for above-mentioned lighting device, no matter be in manufacture or assembling process, or in use procedure, maintenance process, all will spend more cost.Another kind of omnidirectional lighting device is the effect that application principle of reflection realizes omnidirectional lighting.WO 2009/059125A1 discloses a kind of lighting device, wherein unique light source is disposed in the bottom section of basin shape reflector, can light be reflected towards large as far as possible region by means of the reflecting surface of reflector thus, but must ensure that reflector has enough large reflecting surface simultaneously.Therefore the volume of this lighting device is larger.
Summary of the invention
