Description

Light-emitting diode lamp and its application in landscaping street lights

The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp which can be applied to a street lamp.

In view of the many advantages of light-emitting diodes (LEDs), such as small size, short reaction time, low power consumption, high reliability, and high mass production feasibility, light-emitting diodes have gradually replaced traditional light-emitting elements, such as incandescent light bulbs. Or fluorescent lights.

However, since the light-emitting diode generates heat when it is operated, if the heat energy cannot be efficiently removed, the luminous efficiency of the light-emitting diode is degraded, and the life of other power supply elements is shortened.

When the LED light source is applied to the street lighting application of art landscaping, but it is not matched with a good heat dissipation solution, the LED and the electronic circuit components are affected by the heat.

The light projection produced by various types of wicks can be combined with secondary optical components to bring different aesthetic effects.

The lampshade of the present invention is used for accommodating a packaged light-emitting diode module, and the light generated by the operation of the light-emitting diode is penetrated. It can be easily understood that the present invention is not characterized by the material of the lampshade, and therefore materials known to be applicable to the lampshade material of the light-emitting diode lamp, including but not limited to glass or plastic, are available for the present invention.

The electrical connection portion of the present invention is for receiving power from an external power source and is appropriately converted or protected to provide a voltage/current required for operation of the light-emitting diode. In a typical embodiment, the electrical connection portion 30 includes a The lamp body 31, a lamp cap 32 or a combination thereof, wherein the lamp body 31 is required to accommodate electronic circuit components required for conversion or protection, and in some embodiments, the lamp body 31 is composed of a heat dissipating material. Thereby, the heat generated by the LED module and the electronic circuit component is removed; the function of the lamp cap 32 is to fix the LED lamp to the socket, including but not limited to the public or special specifications such as E27 or E40. The socket, in some embodiments, the interior of the base 32 can accommodate electronic circuit components.

The electronic circuit component of the conversion or protection includes, but is not limited to, a rectifier module, a driving module, a dimming module, a current limiting module or a combination thereof, and the electronic circuit components are disposed in the lamp body 31 or the lamp cap 32. The middle or cylinder wicks 10 are each independently assigned to three.

The invention is characterized by the arrangement and use of heat dissipating members on the lampshade, thereby optimizing the heat dissipation solution. Due to the heat generated by the operation of the light-emitting diode, the light-emitting diode lamp of the prior art relies on contact heat conduction, and the removal of heat through the electrical connection portion easily affects the operational efficiency and life of the electronic circuit component in the electrical connection portion. The heat-dissipating member of the light-emitting diode lamp of the present invention is located at the opposite end of the electrical connection portion of the lamp cover and is fixed to the column wick, so that the heat energy is completely or mostly diffused into the air through the heat-dissipating member, thereby avoiding the traditional electrical connection. The disadvantage of heat dissipation.

In some implementations, the heat dissipating member has heat dissipating fins or heat dissipating holes. In addition, the heat dissipating member can achieve visual optimization in accordance with the shape of the lamp and the aesthetic design.

In some embodiments, the LED lamp of the present invention is provided with a fan that is disposed on the heat dissipating member and electrically connected to the electrical connection portion, and is configured to transmit air around the heat dissipating member through the fan. Improve the heat dissipation of the heat sink.

In a preferred embodiment, the cylindrical wick 10 is electrically connected to the electrical connection portion 30 via a conductive member 14, in which the cylindrical wick 10 and the electrical connection portion 30 are connected by only the conductive members. The heat generated during operation of the LED module 11 cannot be transferred to the electrical connection portion 30 in a small amount, thereby preventing high temperature from affecting the operational efficiency and life of the electronic circuit components in the electrical connection portion 30.

For a part of the implementation, reference may be made to the second figure. In addition to all the components of the LED body lamp of the first figure, the lamp body 31 and the conduction member of the electrical connection portion 30 are provided. 14 may have a second heat dissipating member 50, which is composed of a material that is easy to dissipate heat, and may increase the heat dissipating effect in the form of a heat dissipating fin or a heat dissipating hole according to requirements. The function of the second heat dissipating member 50 is twofold: (1) the heat generated by the operation of the light emitting diode module is transmitted to the second heat dissipating member 50 through the air in the conducting member 14 or the inner space 21, and the second heat dissipating member The heat can be dissipated into the air; (2) the heat generated during the operation of the electronic circuit components inside the electrical connection portion 30 can be removed through the second heat dissipating member 50, thereby effectively improving the performance and life of the electronic circuit components.

Referring to the third figure, the present invention further provides a light-emitting diode modeling street lamp 300, comprising: a modeling street light lamp 310; and a light-emitting diode lamp 100 combined with the foregoing lamp.

In some implementations, the heat dissipating component of the LED lamp 100 can be extended or compressed according to the special shape or special component of the lamp, and then contacted with the lamp 310 to make the heat generated by the LED module work. It is conducted to the lamp 310 through the heat dissipation member.

In some implementations, the heat dissipating member of the LED lamp can be specialized as one part of the overall street lamp without affecting the heat dissipation effect.

In some implementations, the street lamp of the present invention further includes a fan that allows heat generated by the operation of the LED module to be dissipated into the air through the air.
