Problems solved by technology
[0004] However, the above-mentioned LED lighting device has the following disadvantages in actual use: Since the heat dissipation efficiency provided by the heat dissipation plate 42 is related to its area size, and the area of the heat dissipation plate 42 provided by the lamp tube 40 is limited, the heat dissipation effect cannot be improved. , the heat energy generated by LEDs cannot be fully removed, and the luminous efficacy of overheated LEDs will be reduced and the service life will be reduced. Therefore, how to improve the heat dissipation efficiency so that LEDs can emit light stably at an appropriate temperature needs to be improved.

The invention relates to a lamp panel and a light-emitting diode illumination device with the same. The light-emitting illumination device is provided with at least one lamp tube on the lamp panel; the lamp panel is made of a heat conduction material; a heat conduction board is arranged on the lamp panel corresponding to each lamp tube; each lamp tube is provided with a transmitting cover; the transmitting cover is connected with a circuit board; a plurality of light-emitting diodes are arranged on the circuit board; and the circuit board is mutually adhered to the heat conduction board in a contact manner. Thus, heat energy generated when the light-emitting diodes emit light can be transmitted to the lamp panel through the heat conduction board, so that the heat energy can be ensured to be discharged by using the large-area lamp panel, and the heat radiation efficiency can be effectively improved.
Description
technical field [0001] The invention relates to a lighting device, in particular to a light emitting diode lighting device which uses light emitting diodes as a light source, and the heat energy generated by the light emitting diodes can be transferred to a lamp panel to provide a good heat dissipation effect. Background technique [0002] Light emitting diode (LED) is a kind of semiconductor device, which has the advantages of high brightness, power saving, and environmental protection. In recent years, it has gradually replaced traditional light sources and is widely used in various lighting devices. [0003] See Figure 7 As shown, it is a light-emitting diode lighting device in the prior art. Its main structure is that a plurality of lamp tubes 40 are arranged at intervals on a lamp panel 30, and the lamp tubes 40 have a light-transmitting cover 41 and the light-transmitting cover 41 A heat dissipation plate 42 is connected to the top, and a circuit board is arranged in ...
