Description
Technical field
The utility model relates to optical technical field, particularly a kind of optical lens and lighting.
Background technology
Along with the fast development of modern lighting engineering, the lighting apparatus with plurality of advantages such as high brightness, low energy consumption, long service life, environmental protections is widely used in the illuminating industry.Such as in road lighting, generally adopting LED (Light Emitting Diode emitting semiconductor) as the lighting source amount of saving energy.But led light source belongs to spot light, exists effective range of exposures little as the LED of road illuminating lamp, irradiance problem pockety.Adopt reflector that the light that led light source sent is reflected and spreads in order to solve the existing part light fixture of this technical problem, though can effectively enlarge the light area like this, the light orientation that led light source is sent projects the zone of demand, but the Illumination Distribution inequality, there is tangible dark space on both sides.And, before one group of led light source, install a public secondary lens additional, to reach the optically focused purpose in order further to improve the light extraction efficiency of LED.Yet, must default distance between led light source and the secondary lens, the light that causes entering secondary lens is veiling glare, so the light emission rate that secondary optics is handled is very low, hot spot is difficult to control.
The utility model content
Little in order further to solve in the prior art the effective range of exposures of spot light, the problem that light emission rate is very low, the utility model embodiment provides a kind of optical lens and lighting, corresponding spot light of this optical lens wherein, not only range of exposures is big for the feasible light that penetrates through this optical lens, and light emission rate is higher.
In order to realize above-mentioned utility model purpose, the utility model embodiment provides a kind of optical lens, described lens comprise by the crossing lens body of forming of two packaged lens levels, can fixedly connected with pedestal in described lens body bottom, when fixedly connected with pedestal in described lens body bottom, the depressed part of corresponding light source is arranged in described base bottom; When described lens body bottom does not need to fixedly connected with pedestal, the depressed part that corresponding light source is arranged in described lens body bottom, like this when depressed part disposes a spot light, such as the LED lamp, the light that spot light sends can form range of exposures after optical lens reflects, scatters big, the light that light emission rate is higher.
In order effectively to support, fix this optical lens in lighting, the utility model embodiment also is provided with back-up block in base bottom or lens body two bottom sides.
More even for the emergent ray irradiance is distributed, described depressed part is positioned at the central authorities of described base bottom or lens body bottom.
For the light that spot light is sent directly penetrates through this optical lens secondary, loss in the middle of reducing, the shape of depressed part is corresponding with the shape of LED lamp.Such as when the LED lamp be shaped as sphere the time, described depressed part be shaped as hemispherical.
In order to reduce veiling glare, increase illuminating effect, the cambered surface on depressed part and/or the lens body is a burnishing surface.
Pedestal and packaged lens can Merlon or polymethacrylates be material.
For economical with materials, base shape is corresponding with the lens body bottom shape.
In order to realize above-mentioned utility model purpose, the utility model embodiment also provides a kind of lighting, this lighting comprises the described optical lens of several the utility model embodiment, and each the LED lamp in the described lighting is embedded in the depressed part of a described optical lens.It is big to form range of exposures after the light that sends of each LED lamp can both reflect, scatter through optical lens like this, and the light that light emission rate is higher makes that the illuminating effect of lighting is better.
Described optical lens of the utility model embodiment and lighting are not only simple in structure, and range of exposures is big, and light emission rate is higher.
