Description

The present invention relates to a full-emission LED lamp for a vehicle capable of full emission including a front end and a side end, and more particularly to a full-emission LED lamp applied to a car or motorcycle lamp or a similar structure.

The main reason why LEDs (Light Emitting Diodes) are called lighting in the new century is because LEDs have advantages such as long service life, low power consumption, and low pollution. For this reason, it is regarded as the key to the lighting industry revolution, and many countries consider LEDs to be a new industry that should be developed in the future.

Many of the LED products commonly used in the current market are traffic signals, warning lamps, decorative lamps for business locations, and lighting for advertising signs. There is no.

Generally speaking, a conventional LED light emitting diode is provided with a concave groove in a pedestal, a chip is connected in the concave groove, the chip is connected to another support by a connecting line, and finally a light-transmitting layer. By integrally molding the base, the chip, the connecting line, and the other support body by injection molding, a light emitting diode is completed.

However, in the above-described conventional LED light emitting diode, when the power is turned on, the chip is coupled into the groove of the pedestal, so that the light emitted from the peripheral edge and bottom surface of the chip is disturbed by the groove and reflected. Therefore, the chip can emit light only to the front, and cannot emit light to the periphery of the LED light emitting diode. When such an LED lamp is used as a car or motorcycle lamp, it is not possible to use the reflection device in the original lamp or to enhance the illumination effect by coating.

In the market, LED bulbs have been developed in which a plurality of LEDs are combined to form a lamp column. For example, in the “vehicle lamp” disclosed in Chinese Patent No. M379534, an LED lamp column is formed by combining a plurality of LEDs in order to increase the irradiation angle of the LEDs. However, this method greatly increases manufacturing costs.

Taiwan Patent No. M379534 Specification

  Therefore, the present invention has an object to provide a full-light-emitting LED lamp that has a light-emitting effect on the periphery in addition to the light emitted from the front and can achieve the effect of full-light-emitting with only one LED. .

In order to achieve the above-mentioned object, a full-emission LED lamp for a vehicle according to the present invention comprises a lamp base, a lamp plate, an optical fiber light guide tube, and a lamp cover. A chip is provided, and two pins are provided below the lamp plate. The lamp plate is provided in the housing space of the lamp pedestal, and the pins provided below the lamp plate protrude from the perforations of the lamp pedestal. The optical fiber light guide tube is disposed on the LED chip of the lamp plate, and the lamp cover covers the optical fiber light guide tube and is connected to the lamp base.

  According to the present invention, since the light emitted from the LED light-emitting diode chip can be diffused in all directions using an optical fiber light guide tube, the light emission effect of the LED lamp is further improved.

It is the exploded view which showed the structural member of the Example of this invention. It is the perspective view which showed the external appearance of the Example of this invention. It is sectional drawing which showed the Example of this invention. It is explanatory drawing which showed the state which light emission of the Example of this invention act | operated.

As shown in FIG. 1 to FIG. 3, the vehicle full light-emitting LED lamp 1 according to the present invention includes a lamp base 10, a lamp plate 11, an optical fiber light guide tube 12, and a lamp cover 13. A housing space 101 is provided inside the lamp pedestal 10, two perforations 102 are provided at the bottom of the housing space 101, a connecting portion 103 is provided at the top of the housing space 101, and the connecting portion 103 in this embodiment is It is a fitting edge that has a stepped shape.

The lamp plate 11 constitutes a circuit board, and the circuit board is smaller than the accommodating space 101 of the lamp base 10. An LED chip 111 is connected to the top surface of the lamp plate 11, and two pins 112 are provided on the bottom surface of the lamp plate 11.

The cross-sectional area of the optical fiber light guide tube 12 is provided in accordance with the size of the LED chip 111 on the lamp plate 11, and the cross-sectional area of the optical fiber light guide tube 12 is preferably slightly larger than that of the LED chip 111. The light guide tube is attached in the housing space of the lamp cover.

The inside of the lamp cover 13 is provided with a housing space 131, and a connecting portion 132 is provided at an opening portion of the housing space 131. The connecting portion 132 of the lamp cover 13 is provided in accordance with the lamp base 10 connecting portion 103. It is a stepped fitting edge corresponding to each other.

The lamp plate 11 is disposed in the accommodating space 101 of the lamp base 10, and the two pins 112 at the bottom of the lamp base 11 protrude from the perforations 102 of the lamp base 10, and the ends of the two pins 112 are processed.
