Technical Field

The utility model relates to an L ED lamps and lanterns especially relate to an install the radiator unit in L ED lamps and lanterns power storehouse, are applicable to high-power, casing/the great L ED lamps and lanterns of power generate heat.

Background

With the rapid development of high technology, electronic products become intelligent and complicated, the volume of electronic components tends to be miniaturized, and the density per unit area is higher and higher. The direct effect of this is that the electronic product generates more and more heat during operation. If there is no good heat dissipation means to remove the heat generated by the electrons, these excessive temperatures will cause the electronic device to generate electron dissociation and thermal stress, which will result in the overall stability being reduced and the lifetime of the electronic device itself being shortened. Therefore, how to remove the heat to avoid overheating of the electronic components has been a non-negligible problem.

The L ED lamp is a solid semiconductor device capable of converting electric energy into visible light, and can directly convert electricity into light, and the solid semiconductor device has the characteristics of durability, energy conservation and the like, so the solid semiconductor device is widely applied to various aspects of daily life of people, for example, the lamps are increasingly used in L ED offices, home decorations, luminous advertising signs and street lamps for lighting, when the L ED lamp works, as the current thermal effect is generated after current is conducted and current flows, the more the power is, the more the heat is dissipated, the constant temperature rise of L ED is until the stability, namely L ED temperature rise is generated, in practical application, the L ED temperature rise is a main factor causing the performance degradation and the failure of L ED, and therefore, the service life and the performance of L ED can be improved by timely guiding the heat generated by L ED.

L ED lamp need dispose specialized heat sink to dispel the heat, for example Chinese patent CN106085165A discloses a L ED lamp with heat dissipating double-fuselage, set up under the base, the heat dissipating double-fuselage includes body, heat pipe, heat dissipating fin, temperature pick-up and controller, etc., the apparatus structure is complicated, the cost of manufacture is high, for example Chinese patent invention patent No. Z L0201120307527.0 discloses the heat-dissipating type L ED bulb heat dissipating double-fuselage of patent No. L ED bulb heat dissipating double-fuselage includes bulb support and heat sink mounted on support, these heat sinks are contacted with the heat dissipating part of L ED lamp body directly, enable heat to transmit to the heat sink, the heat sink is distributed radially and equipped with multiple heat dissipating through holes, the bottom surface of the cup portion of the lamp has multiple openings that can let the heat sink penetrate, the heat sink penetrates and fixes through the opening.

Another issue that is easily overlooked is that the power supply plays a key role in the lifetime of L ED lamps, which may become a bottleneck in the deployment of L ED lighting systems, generally, L ED lamps have a much longer normal life than the driving power supply, for example, Cree's X L amp series product has a life of 50000 hours, while the driving power supply has a normal life of about 2000 hours, so that L ED lamps have a life span that depends mainly on the driving power supply, and as L ED lamps have more and more power, the power required by the power supply is increasing, the power supply has a reduced duration of operation due to natural heat dissipation, which severely affects the stability and life of L ED lamps, and is very prone to burning out due to excessive temperature after long-term use.
