Abstract

An LED-lamp comprises a lamp-holder, a transparent-shade, a light-emitting-module, and a light-guide. The lamp-holder and the transparent-shade are assembled so as to define an accommodating-space. The lamp-holder has a platform-part protruding into the accommodating-space. The light-emitting-module is mounted to the platform-part and comprises a PCB and at least an LED set on the PCB. The light-guide is mounted to the platform-part and covers the light-emitting-module. The light-guide has an external diameter longer than that of the platform-part. The use of the light-guide permits light emitted from the LED passing therethrough and emission of light in a lateral direction thereof. Further, the light emitted in the lateral direction of the light-guide can pass through the transparent-shade which results in an increase in the light-emitting angle of the LED-lamp.

Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode (LED) lamp, and more particularly to a light-emitting diode lamp which can increase the light-emitting angle. [Prior Art] Since the light-emitting diode has the advantages of power saving, long service life, and environmental protection, it has been gradually applied to the general lighting field. However, in the field of light bulbs, incandescent lamps are still the mainstream. This is because the light-emitting diodes used in light bulbs have an exit angle of about 120 degrees, which makes the light-emitting angle of the bulbs also about 120 degrees. Generally, the angle of light emitted by incandescent lamps is significantly smaller. There is a bulb structure that utilizes a long cylindrical light guide to increase the angle of illumination. However, the long cylindrical light guide body makes the light transmission distance long, which may cause light loss and reduce light extraction efficiency, so there is still room for improvement. Therefore, how to increase the light-emitting angle of the light-emitting diode bulb is still a problem that needs to be overcome. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a light-emitting diode lamp that can increase the exit angle. Therefore, according to a preferred embodiment of the present invention, the light-emitting diode lamp of the present invention comprises a lamp holder, a light-transmitting lamp cover, a light-emitting module and a light-guiding lamp holder combined with the light-transmitting lamp cover, and jointly define In a housing space, the lamp holder 2 has a platform portion that protrudes in the accommodating space. The light-emitting module is disposed on the flat σ°卩 of the lamp holder, and includes a circuit board and at least one light-emitting diode 4 disposed on the circuit board. 201209348 body light guide member is disposed on the platform portion and covers the light-emitting module, and the light guide The outer diameter of the piece is larger than the outer diameter of the platform portion. According to a preferred embodiment of the present invention, the illumination module is disposed on the platform portion to increase the angle of refraction of the light emitted by the illumination module by the light guide member, so that the light can be emitted from the side of the light guide member, thereby emitting light. The lampshade can improve the overall light-emitting angle of the light-emitting diode lamp. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 1 and FIG. 2, a first preferred embodiment of the light-emitting diode lamp of the present invention comprises a lamp holder 1, a light-transmitting lamp cover 2, a light-emitting module 3 and a light-guiding member 4.

The outer diameter (10) of the platform portion 12 is 35 mm. And by using the surface @ 422 to increase the refraction angle of the light, and using the bevel area 431 to destroy the total reflection, the light can be emitted by the bevel area 431. In the actual size, the curved surface region 422 on the longitudinal load surface (as shown in FIG. 2) may have a cone angle of a conic parameter between 〇1 and 〇9, or may have a radius of curvature between ! The rounded corner to 5 mm is a taper angle of 0.4 in the present embodiment. The angle a of the chamfered portion of the bevel @ 431 with respect to the plane of the bottom surface 41 may be between 2 and 6 degrees, which is 28.1 degrees in this embodiment. The thickness of the light guiding member 4 (the distance between the bottom surface 41 and the planar area 42 ι of the top surface 42) may be 5 to 2 mm, which is ugly in this embodiment. Therefore, the light emitted by the light-emitting module 3 is incident into the light guide 4 through the curved recess 44 of the light guide 4, and the light that hits the flat area 421 of the top surface 42 can be directly emitted (a small amount of light may have total reflection, but When it is transmitted to the bevel area 431, it can still be emitted. The light that hits the curved surface of the top surface 42 will increase the refraction angle of the light due to the curvature of the curved surface area 422.
