Description

High heat dissipation LED lamp structure

The present invention relates to a structure of a high-heat-dissipation light-emitting diode lamp, relating to a lighting device, and belongs to the technical field of international patent classification H05B.

Reviewing the structure of the current LED (LED) lamp, the heat sink is designed outside the lamp body, for example, the heat dissipation structure of the Republic of China patent M431433 bulb type LED lamp, because the heat dissipation zone has no outer casing to maintain the vacuum generated by the rise of the hot airflow. , causing the problem of low heat dissipation efficiency.

The main purpose of the present invention is to provide a high-heat-dissipation LED lamp structure, comprising: a cone-shaped lamp body having a plurality of vent holes on one surface; a light source plate affixing a plurality of LEDs, the plate fitting device being in the cone-shaped lamp body One end of the upper and lower openings; a heat dissipating body disposed inside the cone-shaped lamp body, the heat dissipating body is mounted on the other side of the LED of the light source plate; a set of power modules, the module is placed on the cone-shaped lamp body One end of the opening, the position is opposite to the light source plate of the LED; an external power supply seat.

The high heat dissipation LED lamp structure has two sets of multiple vent holes at the upper and lower ends of the cone-shaped lamp body, or uniformly distributes a plurality of vent holes on the surface of the cone-shaped lamp body, and the LED is selected. The lamp cone-shaped lamp body can be a trumpet type, a square tube type, or a cylinder type, and the heat dissipating body disposed in the LED lamp body is a columnar body having upper and lower strip fins, The structure having a plurality of upper and lower direction holes or the heat dissipating body is one or a combination of the high heat radiation film structures.

The operation principle of the novel lamp body structure is to isolate the gas by using a cone-shaped outer casing. In the airflow channel, when the airflow is heated by the heat dissipation fins, the heat dissipation holes, or the high heat radiation film, the airflow is expanded to form a hot airflow, which rises due to a decrease in the specific gravity of the gas, and the hot airflow rises in the state of the cone-shaped outer casing isolation. A certain degree of vacuum causes the chimney effect of cold air to be continuously sucked in by the passage opening below the fins, so as to reduce the light decay and ensure the life of the LED lamp.

Embodiment 1

The operating principle of the high-heat-dissipating LED lamp structure is to isolate the hot gas in the airflow channel by using the cone-shaped lamp body (2), and enter the cold airflow (91) through the light source plate (3) and the heat-dissipating fin column when the lower end enters the airflow channel. The body (42) expands to form a hot air stream after heating, and rises due to a decrease in the specific gravity of the hot gas. In a state in which the cone-shaped outer casing is isolated, a certain degree of vacuum is formed by the hot air flow rising, so that the cold air is formed by the fins below the fins. The passage opening is continuously sucked, and the chimney effect of the hot air flow (92) is discharged from the upper end to achieve heat discharge from the gas flow, thereby reducing the light decay and ensuring the life of the LED lamp.

Embodiment 2

The high-heat-dissipation LED lamp structure (1) embodiment of the present invention can refer to the first figure, which is a high-heat-dissipating LED lamp structure (1) of the present invention, comprising: a horn type cone-shaped lamp body (2), a cone There are two sets of multiple vent holes at the upper and lower ends of the lamp body (2), which are divided into a lower vent hole (21) and an upper vent hole (22), and are open at the lower end of the cone-shaped lamp body (2). A light source plate (3) which is attached to a plurality of LEDs is disposed at an open end of the tubular lamp body, and the device is attached to the other side of the light source plate of the plurality of LEDs, and a heat dissipating fin column body is further disposed. On the other side of the LED light source plate, and a power module (7) fixed to the other open end of the light source plate (3) in the cone-shaped lamp body (2), and outside the cone-shaped lamp body (2) Set an external power supply connector (8).
