The present invention relates to a light emitting device used for a kind of lighting or interior use.

The use of light-emitting LEDs for lighting, caution signs, interiors, and the like in terms of long service life and saving electricity is already common now. The LED used as a stop lamp of a vehicle typically arranges several LEDs in a straight line, and when the circuit is driven by the brake operation of the vehicle, the LED emits light to perform a caution indication function. In addition, automotive stop lamps, direction indicator lamps, or interior lamps in cars are gradually using LED as a light source.

However, since the intensity of the light emitted by a single LED is limited, typically several LEDs are configured to emit light at the same time, but in this case, the number of LEDs applied to the light bulb is too large to reduce the manufacturing cost In addition, the light emitted directly from the LED has a disadvantage that it is not soft.

An object of the present invention for solving the above problems is to solve the problem that it is impossible to reduce the manufacturing cost due to the application of more LEDs than the current LED bulb.

Another object of the present invention is to solve the softness of the conventional LED light.

The technical means of the present invention for achieving the above object is a light reflecting member of one or a small amount of LED as a light source, and emits light in the axial direction of the end of the long linear light guide rod end portion of the light guide rod part and the other cross section By reflecting off, the entire light guide rod generates a soft light, which can be used for lighting, caution signs or interior purposes.

According to another kind of technical means of the present invention, LEDs are installed at both ends of symmetrical ends of the light guide rods, and a pair of LEDs emit light in a direction facing each other so that the light beams are reflected from the light reflection member on a part of the surface of the light guide rods. Thus, the entire light guide rod to generate a soft light.

Another kind of technical means of the present invention is to form a rough surface on the inner light ray zone surface of the light guide rod to cause the light to be refracted, thereby causing the light guide rod to emit brighter and softer light.

The cross section of the light guide rod disclosed by the present invention can be circular, polymorphic and other geometric shapes.

A method of adhering the light reflection member formed on a part of the light guide rod, wherein the light reflection member is separately attached to the light guide rod, or the light reflection member is pre-installed in a mold for forming the light guide rod. The member may be integrally coupled to the light guide rod.

The light reflection member at the end of the light guide rod is fixed in a cap sheet fixed to the end of the light guide rod to reflect the projection light in the axial direction.

A sleeve for fixing the light guide rod is connected to the second end of the body, and the electrical lead extending from the light emitting member of the light guide rod is inserted into the inner space of the body through the bottom of the sleeve, and the bypass saltway It passes through to the outside of the main body and prevents the damage caused by pulling the electric wire as a blocking function of the two clapboards.

In addition, the link connects one coverboard to the side of the main body by a connecting strip, and the coverboard and the main body are fixed to each other by clips and buckles, and the clips and buckles release the fitting to open the coverboard, Seal the space.

The link has a communication hole formed on the side wall of the sleeve, and when the optical induction rod is inserted into the inner hole of the sleeve, the dissolved liquid colloid is injected into the communication hole, and the colloidal agent solidifies and adheres the optical induction rod to the inner hole of the sleeve. Fix it to

In addition, the link is formed with a heat dissipation hole in the body and the cover board, the heat dissipation hole immediately dissipates heat generated during the operation of the electronic components in the internal space of the body.

The present invention adopts a light guide rod to indirectly derive the light rays of the LED, and thus exhibits a soft light effect, and also reduces the manufacturing cost of the light bulb because the number of LEDs is small.
