Abstract
The utility model discloses a light condensing lens of an LED (light emitting diode) lamp, which comprises a circular-table shaped transparent body, wherein a concave cavity is arranged at the end part of the circular-table shaped transparent body; the bottom surface of the concave cavity is a flat one or a protruding curved one, a semispherical bulge is arranged at the middle part of the bottom surface of the circular-table shaped transparent body, and a convex lens is formed between the bottom surface of the concave cavity and the outer surface of the semispherical bulge. The light condensing lens has a simple structure; based on the optical light condensing principle, emergent light of an LED light source is gathered together according to need, thereby achieving the purpose of controlling the angle of the emergent light of the LED light source. Therefore, with high practicability, the light condensing lens is suitable for the lighting field with high requirement for the intensity of the light source.
Description
Technical field
The utility model relates to a kind of LED lamp collector lens.
Background technology
LED is a kind of solid state light emitter of novel concept, with its impayable energy-saving and environmental protection, long-life, controllability high-technology advantage, becomes in recent years one of new and high technology of the tool development prospect in the whole world.
Along with the led light source application more and more widely; Specification requirement for led light source is also increasingly high; Wherein how the emergent light angle of led light source is controlled in the scope that needs; Be about to optic optically focused and introduce the LED technical field, reach the purpose of optically focused and astigmatism, become an important directions of LED technical development with the astigmatism technology.
The utility model content
The purpose of the utility model provides a kind of LED lamp collector lens, and the optically focused of optical field technology is introduced the LED technical field, can assembling on demand the emergent light of led light source.
The technical scheme of the utility model is following:
A kind of LED lamp collector lens; Include the truncated cone-shaped transparent body; It is characterized in that: the end of the said truncated cone-shaped transparent body is provided with cavity; The bottom surface of cavity is the curved surface of plane or projection, and the middle part of said truncated cone-shaped transparent body bottom surface has hemispherical projections, constitutes convex lens between the bottom surface of cavity and the outer surface of hemispherical projections.
Described LED lamp collector lens is characterized in that: be provided with led light source in the described cavity.
Described LED lamp collector lens, it is characterized in that: the edge of said cavity oral area is provided with cannelure.
The beneficial effect of the utility model:
The utility model is simple in structure, utilizes optic optically focused principle with the assembling on demand of the emergent light of led light source, thereby reaches the purpose of the angle of control led light source emergent light, is applicable to the lighting field that the intensity of light source is had relatively high expectations, and is practical.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1; A kind of LED lamp collector lens; Include the truncated cone-shaped transparent body 1, the end of the truncated cone-shaped transparent body 1 is provided with cavity 2, and the bottom surface of cavity 2 is the plane; The middle part of the truncated cone-shaped transparent body 1 bottom surface has hemispherical projections 3, constitutes convex lens between the outer surface of the bottom surface of cavity 2 and hemispherical projections 3.
Be provided with led light source 4 in the cavity 2; The edge of cavity 2 oral areas is provided with cannelure 5, is convenient to install.
The light that led light source 4 sends is after 1 outgoing of the truncated cone-shaped transparent body, and the angle of emergent light can reach below 60 °, has reached the purpose of on demand angle of led light source emergent light being assembled, and is applicable to the lighting field that the intensity of light source is had relatively high expectations.
