Abstract
The invention discloses a light-emitting diode (LED) modulator tube capable of transferring and dissipating heat through a tube body. The LED modulator tube comprises the tube body. A printed circuit board (PCB) is installed inside the tube body. A plurality of LEDs are installed on the front side of the PCB. An element used for controlling the LEDs to emit light is installed on the back side of the PCB. The PCB is connected with a mains supply through two electrodes at the sealed ends of the tube body. The LED modulator tube further comprises a supporting assembly. The supporting assembly is installed on the back side of the PCB and abuts against the inner wall of the tube body. A base pin of each LED is provided with a bent part. An elastic insulating sheet is installed in the position, close to an LED luminous body, between each bent part and the PCB. Each LED luminous body can be attached to the inner wall of the tube body tightly through the elastic force generated by the corresponding elastic insulating sheet. Heat of the LED luminous bodies is transferred and dissipated through the tube body. The top face of each LED luminous body is a curved face matched with the inner wall of the tube body, and the space between each curved face and the inner wall of the tube body is filled with transparent heat-conducting silicone grease. Or the top face of each LED luminous body is a plane, and the space between each plane and the inner wall of the tube body is filled with the transparent heat-conducting silicone grease. The LED modulator tube capable of transferring and dissipating heat through the tube body has the beneficial effects that the structure is simple, the cost is low, the heat dissipation effect is good, and the service life of the LEDs is prolonged.
Description
Technical field
The present invention relates to a kind of LED lamp tube utilizing body heat loss through conduction, LED lamp tube has followed the structure of existing fluorescent lamp, fluorescence radiation is replaced to LED luminescence, and two electrodes of body blind end directly can connect 220 volts of civil powers.
Background technology
LED lamp is assembled on same pcb board by a lot LED usually, in order to improve brightness and luminous efficiency, adopts the working method of high brightness big current, temperature is caused to raise, if can not the maximum temperature of control LED effectively, will directly have influence on the service life of LED, reduce luminous efficiency.
The mode of heat radiation, usually heat transfer is had, heat radiation and cross-ventilation etc., comparatively speaking, cross-ventilated cost is lower, but air is good heat-barrier material, poor by air radiating effect, for this reason, application number be 201010139375.8 Chinese patent disclose a kind of LED, described LED comprises LED chip, cooling base and lampshade, described lampshade is fixed on described cooling base, described LED chip is in described lampshade, described lampshade is filled with heat-conducting gas, this invention LED heat dispersion significantly promotes, can comparatively good berth at a lower temperature, but this complex structure cost is higher, also be inconvenient to safeguard.
Heat conducting effect is better, and common heat dissipating method increases fin etc., and its Problems existing is that cost is higher, structure is more complicated, and volume is larger.The LED lamp of not installing fin rejects heat to lamp lampshade by the air natural of LED illuminator in light fixture usually, then is dispersed in air by lamp lampshade secondary, and twice air heat radiation makes radiating effect obviously reduce.
