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.
Utility model content
The utility model, according to above not enough, provides a kind of LED lamp tube by body heat loss through conduction.
The technical solution of the utility model is:
A kind of LED lamp tube by body heat loss through conduction, comprise: body, in body, pcb board is installed, the front of pcb board is provided with some LED, and reverse side is provided with the components and parts of control LED luminescence, and pcb board is by two Electrode connection civil powers of body blind end, also comprise elastomeric element, this elastomeric element is arranged on the reverse side of pcb board and withstands on the inwall of body, and the spring energy that this elastomeric element produces makes LED illuminator be close to inboard wall of tube body, and LED illuminator is by body heat loss through conduction.
