Abstract
The utility model discloses an LED (Light-Emitting Diode) lamp radiating device, which comprises a metal cylinder member, wherein a thick radiating plastic member is coated on the outer circle of the metal cylinder member in an injection molding way; the surface of the radiating plastic member is provided with a plurality of fins at certain intervals; and a rod body at one end of the metal cylinder member is provided with a screw thread connected with a radiating substrate. The radiating device can be tightly connected with an LED light source and the radiating substrate into a whole, so that the radiating heat-conducting device can be used for rapidly conducting heat generated during lightening of the LED light source from a metal cylinder to radiating plastic, and heat can be rapidly dissipated through the surfaces of multiple groups of radiating fins on the device; and meanwhile, heat can be rapidly conveyed to the radiating substrate through the metal cylinder, and is dissipated through the radiating substrate. Through the two ways, high temperature generated by an LED lamp light source can be lowered effectively in time, and normal operation and illumination of lamplight equipment are ensured.
Description
Technical field
The utility model relates to lighting device, is specifically related to a kind of heat abstractor of the LED of being used for lamp.
Background technology
The LED lamp is safe and reliable as a new generation, the green light source of energy-conserving and environment-protective; Numerous advantages such as have that power consumption is few, luminous efficiency is high, good stability and life-span are long; But the LED lamp is converted into heat at the most of energy of the course of work; And the junction temperature that can cause the diode PN junction of gathering of heat raises, thereby has directly influenced luminous flux sustainment rate and the service life of LED.Therefore, the metals such as aluminium or copper that adopt are used for heat radiation as the airtight shell structure part of LED lamp more in the conventional semiconductors lighting, and the heat that led light source produces, is dispersed in the air through housing to housing through the air special delivery in aluminium base and the housing.But metal shell is in the actual installation use, and the metal shell that particularly adopts the general lighting LED lamp that carries the design of driving power integral compact is in the actual installation process, and metal shell inevitably can touch with people's palmistry as the external structure part of LED lamp; Under present electrical isolation technology and condition; Metal shell is an electric conductor, and when the electric leakage situation took place, the excircle of metal shell will be charged; Electric shock accidents may take place, and there is safety in technology now.Simultaneously, it is shell material that present technology adopts metal fully, owing to influenced by metal surface process equipment, technology, technology and working (machining) efficiency etc., is difficult to the housing presentation quality that reaches desirable.
The utility model content
The purpose of the utility model is to utilize superior heat conductivity ability, ultra heat dispersion, low thermal resistance, insulation, fire-retardant, the lightweight characteristics of heat radiation plastic material; Provide a kind of simple in structure; Heat abstractor easy for installation, as to be suitable for the radiating and cooling of LED lamp; Solve the Electrical Safety risk that the LED lamp exists owing to the use metal shell in the prior art, light fixture weight is bigger, the problem that the image appearance color is single.
The technical scheme that the utility model provides is; A kind of LED heat sink for lamp; Comprise a metal cartridge member, on the cylindrical of said metal cartridge member, adopt the mode of injection mo(u)lding to be coated with a heat radiation plastic member, the spaced surface of heat radiation plastic member is provided with many fins.
In above-mentioned LED heat sink for lamp, on the body of rod of an end of said metal cartridge member, be provided with and be used for the screw thread that is connected with heat-radiating substrate.
In above-mentioned LED heat sink for lamp, said metal cartridge member is copper member.
The utility model is by metal column; Plastic injection-moulded the forming of dispelling the heat realizes closely linking to each other with led light source and heat-radiating substrate, becomes one; Therefore this heat radiation heat-transfer device can be rapidly with led light source when luminous the heat of generation be transmitted to the heat radiation plastics rapidly by metal column; And distribute fast through the many groups radiating fin surface on the device, simultaneously metal column can be delivered to heat-radiating substrate rapidly with heat, distributes through heat-radiating substrate.Through above two approach, can reduce the high temperature that the LED lamp source produces timely and effectively, guaranteed normal operation of light units and illumination.
Description of drawings
Fig. 1 is the utility model structural perspective.
The specific embodiment
With reference to shown in Figure 1; Design a kind of LED heat sink for lamp; Be provided with a metal cartridge member 1, on the cylindrical of said metal cartridge member 1, adopt the mode of injection mo(u)lding to be coated with a heat radiation plastic member 2, the spaced surface of heat radiation plastic member 2 is provided with many fins 201.
In above-mentioned LED heat sink for lamp, on the body of rod of an end of said metal cartridge member 1, be provided with and be used for the screw thread 101 that is connected with heat-radiating substrate.
In above-mentioned LED heat sink for lamp, said metal cartridge member 1 is copper member.
In above-mentioned LED heat sink for lamp, said metal cartridge member 1 is an aluminium matter member.
In above-mentioned LED heat sink for lamp, said plastics cylinder member 1 is a graphite material.
In above-mentioned LED heat sink for lamp, said metal cartridge member 1 is a nitride material.
Heat abstractor can closely link to each other with light source and heat radiation base stage in very convenient realization; Become one; Therefore this heat radiation heat-transfer device can be rapidly with led light source when luminous the heat of generation be transmitted to the heat radiation plastics rapidly by metal column; And distribute fast through many groups radiating fin surface, metal column can be delivered to heat-radiating substrate rapidly with heat simultaneously, distributes through heat-radiating substrate.Through above two approach, can reduce the high temperature that the LED lamp source produces timely and effectively, guaranteed normal operation of light units and illumination; It is insulator that heat abstractor adopts the heat radiation plastics; The heat radiation plastic overmold is used the LED light fixture of this heat abstractor in the outside of metal column, and lamp outer casing can adopt common ambroin to make; Even the electric leakage situation takes place; Also electric shock accidents can not take place, the utility model can thoroughly solve traditional LED lamp Al alloy shell surface and possibly have the electrical shock safety hazard that causes because of electric leakage when guarantee and realizing the LED good heat radiating.Because the proportion of plastics uses the LED light fixture of this heat abstractor to have light, easy for installation advantage far below the traditional metal aluminium.
