Abstract
The utility model discloses a light dispersing lens of an LED (light emitting diode) lamp, which comprises a bowl-shaped transparent body, wherein a concave cavity is arranged at the end part of the bowl-shaped transparent body; the bottom surface of the concave cavity is an inwards-sunken curved one or a flat one, the bottom surface of the bowl-shaped transparent body is a flat one or a curved one, and a concave lens is formed between the bottom surface of the concave cavity and the bottom surface of the bowl-shaped transparent body. The light dispersing lens has a simple structure; based on the optical light dispersing principle, emergent light of an LED light source is dispersed according to need, thereby achieving the purpose of controlling the angle of the emergent light of the LED light source; therefore, the radiating range of the emergent light of the LED light source is wider and the lighting range of the LED light source is widened.
Description
Technical field
The utility model relates to a kind of LED lamp astigmat.
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 astigmat, and the astigmatism technology of optical field is introduced the LED technical field, can be with the dispersing on demand of the emergent light of led light source, thus improve the illumination zone of led light source.
The technical scheme of the utility model is following:
A kind of LED lamp astigmat; Include the bowl-type transparent body; It is characterized in that: the end of the said bowl-type transparent body is provided with cavity; The bottom surface of cavity is curved surface or the plane that caves inward, and said bowl-type transparent body bottom surface is plane or curved surface, constitutes concavees lens between the bottom surface of the bottom surface of cavity and the bowl-type transparent body.
Described LED lamp astigmat is characterized in that: be provided with led light source in the described cavity.
Described LED lamp astigmat, it is characterized in that: the both sides of the said bowl-type transparent body are provided with mount pad.
The beneficial effect of the utility model:
The utility model is simple in structure; Utilize optic astigmatic principle dispersing on demand with the emergent light of led light source; Thereby reach the purpose of the angle of control led light source emergent light, the radiation scope of led light source emergent light is wider, has improved the illumination zone of led light source.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of LED lamp astigmat includes the bowl-type transparent body 1; The end of the bowl-type transparent body 1 is provided with cavity 2; The bottom surface of cavity 2 is the curved surface that caves inward, and the bowl-type transparent body 1 bottom surface is the plane, constitutes concavees lens between the bottom surface of the bottom surface of cavity 2 and the bowl-type transparent body 1.
Be provided with led light source 3 in the cavity 2; The both sides of the bowl-type transparent body 1 are provided with mount pad 4, are convenient to install.
The light that led light source 3 sends is after 1 outgoing of the bowl-type transparent body, and the angle of emergent light can reach more than 120 °, has reached the purpose of on demand angle of led light source emergent light being dispersed, and is applicable to the lighting field wider to the radiation of light source scope.
Claims (3)
1. LED lamp astigmat; Include the bowl-type transparent body; It is characterized in that: the end of the said bowl-type transparent body is provided with cavity; The bottom surface of cavity is curved surface or the plane that caves inward, and said bowl-type transparent body bottom surface is plane or curved surface, constitutes concavees lens between the bottom surface of the bottom surface of cavity and the bowl-type transparent body.
2. LED lamp astigmat according to claim 1 is characterized in that: be provided with led light source in the described cavity.
