本发明涉及一种LED灯的结构。 The invention relates to the structure of an LED lamp.
LED灯在温度上升时，其光输出会下降，为此，现有的LED灯，其都具有一散热器，灯板与散热器之间设有散热板。LED灯工作时，发光二极管的热从灯板传递到散热板，再传递到散热器，最后从散热器的外周面散发到外部空气中。然而，现有结构的这种LED灯，其构件多，成本也就相对较高。When the temperature of the LED lamp rises, the light output thereof will decrease. For this reason, the existing LED lamp has a heat sink, and a heat dissipation plate is disposed between the lamp board and the heat sink. When the LED lamp is working, the heat of the LED is transmitted from the lamp board to the heat sink, then to the heat sink, and finally to the outside air from the outer peripheral surface of the heat sink. However, the LED lamp of the prior structure has many components and a relatively high cost.
