Description

Light-emitting diode lamp

The invention relates to a lighting device, in particular to a light emitting diode lamp.

As a new generation of third-generation light source, the light-emitting diode light source can not replace the traditional incandescent lamp on a large scale, but it has the advantages of long working life, energy saving and environmental protection, and is generally favored by the market. Moreover, the module composed of the light-emitting diode can be used as a high-power, high-brightness light source, so that the light-emitting diode will widely and revolutionarily replace the conventional light source such as a conventional incandescent lamp, thereby becoming energy-saving and environmentally friendly. The main source of the theme.

At present, a commonly used light-emitting diode lamp includes a light-emitting diode bulb and a lamp holder connected to the bulb. Due to the limitation of the LED device, the light emitted by the LED is only emitted upward or in a specific direction, so that the angle of the light field is less than 180 degrees, which results in a smaller illumination range.

In view of this, it is necessary to provide a light-emitting diode lamp having a large irradiation range.

A light-emitting diode lamp includes a lamp holder and a light-emitting diode module fixed on a top end of the lamp holder, the lamp holder including a light-transmitting bearing portion carrying the light-emitting diode module, the light-emitting The diode module includes a transparent circuit board fixed on the carrying portion and a light emitting diode fixed on the circuit board, and the light emitted by the light emitting diode is emitted in a direction away from the carrying portion. Passing through the carrier and toward the carrier The edge is out.

Compared with the prior art, in the present invention, since the circuit board carrying the light-emitting diode is a transparent circuit board and the bearing portion carrying the light-emitting diode is a light-transmitting structure, the light emitted by the light-emitting diode is away from the light. The direction of the carrying portion is emitted while passing through the carrying portion and exiting the periphery of the carrying portion, thus effectively increasing the light-emitting angle of the light-emitting diode lamp.

1 is a longitudinal cross-sectional view of a light-emitting diode lamp of the present invention.

2 is a light path diagram of the light-emitting diode lamp shown in FIG. 1.

As shown in FIG. 1 , the LED lamp of the present invention comprises a lamp holder 10 , a light-emitting diode module 30 fixed on the top of the lamp holder 10 , and a lamp holder 10 fixed on the lamp holder 10 and covered with a light-emitting diode module. A light transmissive cover 50 of the group 30.

The lamp holder 10 has a horn shape whose width gradually increases from the bottom to the top, and includes a base 11 , a connecting portion 13 and a carrying portion 15 which are sequentially connected from the bottom to the top.

The base 11 is made of a material that is opaque to light and is a cylindrical body having a rectangular cross section. A first electrode 111 is formed on the outer middle of the lower end of the base 11 and a plurality of continuous external threads are formed on the outer periphery of the side wall as the second electrode 113 of the base 11. The base 11 can be applied to the current standard incandescent lamp holder 10.

The connecting portion 13 is made of a material having good thermal conductivity, and is a cylindrical body whose longitudinal section is substantially trapezoidal and penetrates vertically. The width of the connecting portion 13 gradually increases from the bottom end of the connecting portion 13 connected to the base 11 toward the top end of the connecting portion 13 away from the base 11. The width of the bottom end of the connecting portion 13 is equivalent to the width of the top end of the base 11.

The carrier portion 15 is made of a transparent or translucent material, and the carrier portion 15 extends upward from the top end of the connecting portion 13. The carrying portion 15 is a cylindrical body having a trapezoidal longitudinal section and a closed top end. The width of the carrying portion 15 gradually increases from the bottom end of the tubular body connected to the connecting portion 13 toward the distal end of the tubular body away from the connecting portion 13. The width of the bottom end of the carrying portion 15 is equal to the width of the top end of the connecting portion 13, and the bottom end of the carrying portion 15 faces the top end of the connecting portion 13. In the present embodiment, the carrier portion 15 is made of a transparent material.

The light emitting diode module 30 is fixed to the middle of the top end of the carrying portion 15. The light emitting diode module 30 includes a transparent circuit board 31 and a plurality of light emitting diodes 33 disposed on the circuit board. The size of the transparent circuit board 31 is smaller than the size of the top end of the carrying portion 15.

One end of a conductive post 70 is inserted through the top end of the carrying portion 15 and electrically connected to the transparent circuit board 31. The other end of the conductive post 70 is sequentially passed through the carrying portion 15, the connecting portion 13 and electrically connected to the lamp cap 11. The first electrode 111 and the second electrode 113 can supply power to the LED module 30 through the conductive post 70 after the lamp cap 11 is electrically connected to the external power source.

The lamp cover 50 has an inner hollow hemisphere shape, and a bottom end edge thereof is fixed to a top end edge of the carrying portion 15 to cover the light emitting diode module 30 therein.

Referring to FIG. 2 , when the LED device is used, the circuit board carrying the LEDs 33 is a transparent circuit board 31 and the carrying portion 15 of the LED module 30 is transparent. The light emitted by the light-emitting diode 33 can be emitted from the side of the carrying portion 15 located under the lamp cover 50 while being emitted toward the side of the lamp cover 50, as indicated by the arrow, thereby effectively increasing the light emission of the light-emitting diode lamp. angle.
