Description

The present invention relates to an optical structure of a light-emitting diode lamp, and more particularly to an optical structure used for a light-emitting diode lamp with uniform illumination and an expanded illumination range.

Conventionally, fluorescent powder-emitting fluorescent lamps play an important role in daily life lighting, and the long outer shape of the fluorescent lamp widens the illumination range and has been favored by users.

The technology of the light-emitting diode member is advancing day by day, and its power saving advantage is gradually replacing the conventional technology and becoming a new illuminating lamp. In development, since the light-emitting diode members are in the form of granules, in many of the lighting lamps, a plurality of light-emitting diode members are arranged in a matrix, and many of the lighting lamps are square or circular.

  Techniques for further adapting the lighting fixtures of light emitting diode light emitting members to the customs and demands of users include, for example, ROC M3688749 exclusive “light emitting diode lighting”, ROC I320468 exclusive “heat sink structure "Light-emitting diode fluorescent lamps", all of which research and develop fluorescent lamp-type light-emitting diode member illumination lamps.

  However, the granular light emitting diode member is placed in a long illuminating lamp, and the relatively big problem is to form uneven illumination, often corresponding to the outer shape of the light emitting diode member granules. It becomes a bright part area of block 1 block, and many dark part areas are formed in an intermediate gap, and such an effect does not meet the user's lighting requirements.

  Further, the technology for improving these problems achieves the effect of uniformly diffusing light rays by applying a single diffusion film to the inner layer of the tubular translucent mask and etching the irregularities on the translucent film. Reduces the light transmittance and greatly reduces the brightness.

  Accordingly, an object of the present invention is to provide an optical structure for use in a long light emitting diode lamp with uniform illumination and an expanded illumination range, and to solve the above problems.

The present invention relates to a light guide structure 30 of a light emitting diode lamp. The light guide structure 30 includes a heat sink bar 32, a light emitting diode substrate module 34, a plurality of light emitting diode members 36, and a tubular translucent mask 38.

  The heat sink bar 32 is long, preferably made of aluminum, or made of other heat sink material, and has a first guide groove 40 facing outward and a second guide groove 42 facing inward on both sides of the long direction. Although the first guide groove 40 and the second guide groove 42 are not limited to this, they are, for example, fins, have an effect of expanding the heat sink area, and also have a function of a fixing member.
