Abstract
The utility model relates to a novel radiator for LED lamps. A plurality of devices high in heat generation on a drive power source of a lamp are connected with the radiator, and the radiator is then connected with a lamp shell. During connection, efficient thermally conductive grease is applied to the part of the radiator, in contact with the lamp shell, and the radiator is fastened via radiator screws. The respective independent radiating manners in the existing lamp sources and drive power sources are modified to form an integrated radiating structure so as to obtain the radiator. Heat emitted by each device can be conducted to the radiator quickly, the radiator and the lamp shell are fixedly connected by means of minimum heat resistance, and accordingly heat conducted from the power device to the radiator is conducted to the lamp shell at maximum speed, the inner temperature of the cavity of the lamp is equal to that of the lamp shell and the service life of the lamp is prolonged.
Description
Technical field
The utility model relates to a kind of heat abstractor of LED illuminating lamp.
Background technology
Present LED lighting, power supply is respectively different radiators from the radiator structure of light source, as, the radiator of LED explosion-proof lamp power supply, because security reason generally is arranged in the airtight cavity of light fixture, its normal operation circumstances temperature is at 65 ℃--and 110 ℃, even higher.At so high temperature, the LED driving power will be subjected to very large the impact service life, and this is also the undesirable main cause of present LED lighting whole service life.In addition, because light fixture cavity internal temperature is very high, the main power device radiator of driving power must satisfy the requirement of light fixture driving power on thermal capacity and area of dissipation, so radiator can occupy the very large space of driving power, the dissipated power heat that the driving power of structure like this sends, mainly conduct by air dielectric and be radiated on lamp casing, heat transfer efficiency is very low.
The utility model content
The purpose of this utility model is, overcome the shortcoming that exists on existing LED lighting driving power radiator structure, provide a kind of and can reduce light fixture cavity internal temperature, extend light fixture service life, improve the heat abstractor of driving power power device radiating efficiency.
The utility model is achieved in that
The heat abstractor of this LED illuminating lamp, with existing lamp light source and driving power heat-dissipating structure independently separately, change the integral heat dissipation structure into, namely, a plurality of devices large caloric value on the light fixture driving power connect with a radiator, then this radiator is connected with lamp casing.
On described driving power, the large a plurality of devices of caloric value, be power tube, transformer, rectifier bridge etc.
Described radiator connects with lamp casing, refers at the phase synapsis of radiator with lamp casing, and coating high efficacy heat conduction grease (the good heat-conducting medium of a kind of heat transfer) is also used the radiator screw fastening.
the heat abstractor of the utility model, change existing lamp light source and driving power independence radiating mode into the integral heat dissipation structure, the device (as: power tube that on the light fixture driving power, all caloric values are large, transformer, rectifier bridge etc.) fix with the connecting mode of high-efficient low thermal resistance with an integrated radiator, the heat that each device can be sent is transmitted on radiator fast, adopt the connecting mode of minimum thermal resistance to fix in radiator and lamp casing again, the heat that is transmitted on radiator with regard to energy guaranteed output device like this is transmitted on lamp casing with the fastest speed, make light fixture cavity internal temperature and lamp casing basically identical.The heat of lamp casing and light fixture environment for use medium are gone out by heat transfer type Quick diffusings such as conduction, convection current, radiation, have in enough thermal capacity and area of dissipation situation at lamp casing, and lamp casing temperature and environment temperature differ generally at 20-40 ℃.Therefore, adopt this radiator and radiator structure to reduce largely light fixture cavity internal temperature, extend light fixture service life.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is done and further entered explanation.
In figure: element thermal conductive surface (5) is the surface of the short contact distance of heating power components and parts and radiator.
Power tube trip bolt (6) is in order to make heating power components and parts and radiator ensure maximum contact pressure, to reduce thermal-conduction resistance and the tightening member that uses.
Radiator screw (7) is in order to make radiator and lamp outer casing ensure maximum contact pressure, to reduce thermal-conduction resistance and the tightening member that uses.
Radiator thermal conductive surface (8) is the surface of the short contact distance of radiator and lamp outer casing.
During installation, power tube (4), transformer (3), the rectifier bridge that on the light fixture driving power, caloric value is large connected with radiator (2).Again at this radiator (2) with lamp casing (1) connection place coating high efficacy heat conduction grease (the good medium of a kind of commercially available thermal conductivity) and use fastened by screw.
Claims (3)
1.LED the novel radiating device of illuminating lamp is characterized in that: a plurality of devices that caloric value on the light fixture driving power is large connect with radiator (2), then this radiator (2) is connected with lamp casing (1).
2. the novel radiating device of LED illuminating lamp according to claim 1, is characterized in that, a plurality of devices that described caloric value is large are: power tube (4), transformer (3), rectifier bridge.
