Problems solved by technology

[0004] In order to improve the above problems, most manufacturers combine and arrange a plurality of light-emitting diodes to concentrate the light to achieve the problem that the irradiation range is too small; however, the increase in the number of light-emitting diodes increases the power required to drive the light-emitting diodes, which cannot effectively It achieves the effect of saving electricity, and the price of LED lamps is much higher than that of traditional light sources, which makes users less willing to use LED lamps

Embodiment Construction

[0040] Referring to FIG. 1 and FIG. 2 , both are perspective views of the optical element according to the first embodiment of the present invention. The optical element 10 is suitable for being arranged on a light emitting diode 90, so as to change the light intensity distribution of the light emitted by the light emitting diode 90, and expand the light emitting angle of the outgoing light. The light emitting diode 90 is an light emitting diode chip as an example, and it is not limited to this in actual implementation.

[0041] The optical element 10 can be made of transparent materials such as plastic, glass, silicone rubber or silicone resin by injection molding or compression molding, and the optical element 10 is integrally formed. The optical element 10 has a light-transmitting body 11 , and the light-transmitting body 11 includes a light guide column 12 and an extension portion 14 . In this embodiment, the light guide column 12 is a circular column, and in actual imple...

Abstract

The invention discloses an optic element and a lighting device comprising the optic element. The optic element matches with a light emitting diode in combination, thereby working as an illuminating light source. The optic element includes a light-transmitting body including a light guide post and an extending part. The light guide post is provided with a top face and a bottom face. The bottom face is provided with a groove. The extending part extends outward from the periphery of the top face. The tail end of the extending part is provided with a light outgoing face. The light emitting diode is arranged in the groove and emits light beams to the optic element. The extending part guides the light and enlarges the outgoing angle of the light beams.

Description

technical field [0001] The invention relates to an optical element, in particular to an optical element capable of effectively enlarging the light emitting angle and a light-emitting device with the optical element. Background technique [0002] Light emitting diode (light emitting diode, LED) is a kind of semiconductor element, which mainly converts electrical energy into light energy through semiconductor compounds to achieve luminous effect. Therefore, it has the advantages of long life, high stability and low power consumption, and has been widely used. It is widely used in home, office, outdoor and mobile lighting to replace traditional non-directional light sources such as lamp tubes and incandescent bulbs. [0003] Since the light emitting diode is a point light source and has high directivity, the illuminated area of ​​the light emitting diode is narrower than that of the traditional light source, and the luminous brightness gradually decreases with the increase of ...
