Abstract
The utility model relates to an LED optical lens, which comprises a cone-shaped lens body, wherein an LED lamp groove is formed in the small end face of the cone-shaped lens body; the technical key point of the utility model lies in that the bottom wall of the LED lamp groove sinks inwards gradually towards the middle of the bottom wall from the edge of the bottom wall; a cone-shaped cavity is formed in the cone-shaped lens body; a cylindrical cavity is formed in the large opening end of the cone-shaped cavity and extends towards the big end face of the cone-shaped lens body. The LED optical lens has the benefits that the structure is simple, the light condensation ability is high, and the light condensation angle is around 3 degrees.
Description
[technical field]
The utility model relates to a kind of LED optical lens.
[background technology]
The advantages such as light-emitting diode luminous efficiency is high, power consumption is few, long service life are widely used and lighting field, but because its light sending comparatively disperses, therefore all can adopt lens to improve light-gathering.Existing optical lens structure complexity, light-gathering is poor.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, LED optical lens that light-gathering is good is provided.
In order to address the above problem, the utility model by the following technical solutions:
A kind of LED optical lens, comprise tapered lens body, the little end surface of described tapered lens body is provided with LED light trough, it is characterized in that: the diapire of described LED light trough is indent gradually from edge to middle part, in described tapered lens body, be provided with conical cavity, the large openend of described conical cavity is provided with the cylindrical cavity extending to the big end surface of described tapered lens body.
A kind of LED optical lens as above, is characterized in that: described conical cavity with conical cavity coaxial and axis by the center of described LED light trough.
A kind of LED optical lens as above, it is characterized in that: described tapered lens body major part one end face is provided with the step cutting pattern that diameter is greater than tapered lens body major part one end diameter, and described step cutting pattern is provided with the exiting surface step that diameter is less than step cutting pattern.
A kind of LED optical lens as above, is characterized in that: described tapered lens body comprises inferior pyramidal body and the epicone body in described inferior pyramidal body upper end, and the cone angle of described inferior pyramidal body is greater than the cone angle of described epicone body.
A kind of LED optical lens as above, is characterized in that: the stub end cylindrical of described tapered lens body is circumferentially with for being arranged on two elastic cards on shell.
The beneficial effects of the utility model have: the diapire of LED light trough is indent gradually from edge to middle part, and the middle part of tapered lens body adopts conical cavity, cylindrical cavity, can effectively improve the light-gathering of light source, and its optically focused angle can be controlled at 3 degree left and right.
