Abstract
The utility model discloses an LED (light emitting diode) columnar lamp with a built-in radiator. The LED columnar lamp comprises a columnar PC (polycarbonate) cover, a rear cap, a power source, the radiator, a lamp holder and aluminum substrates with LEDs, wherein the power source is arranged in an inner cavity of the rear cap; the lamp holder is connected to the tail end of the rear cap; the columnar PC cover and the radiator are fixed on the top of a center plate; the radiator is positioned in an inner cavity of the PC cover and is provided with at least eight side surfaces; and the aluminum substrates with the LEDs are fixed on the side surfaces of the radiator. The columnar PC cover is fixed on the rear cap through the center plate, so that the power source in the rear cap is prevented from being in direct contact with the aluminum substrates, and heat dissipation is facilitated. After the aluminum substrates are fixed on the side surfaces of the radiator, the heat dissipation performance of the LED columnar lamp is effectively improved, the service life of the LED columnar lamp is prolonged, and the illumination power is increased. Compared with the prior art, the LED columnar lamp has the advantages of high heat dissipation effect and high power.
Description
[technical field]
The utility model relates to technical field of lighting fixtures, particularly the built-in LED cylindrical lamp of a kind of radiator.
[background technology]
At present, realizing carbon reduction, green illumination cry surging period, incandescent lamp is eliminated just gradually, the substitute is to take the novel green lighting source that LED cylindrical lamp is representative.The advantage of LED cylindrical lamp is long service life, LED power consumption is few, brightness is high, colour rendering index is high, save the energy, and environmental protection is pollution-free, solves power consumption and the pollution problem of conventional incandescent, builds warm romantic house atmosphere.
Current LED cylindrical lamp structure exists unreasonable, and it is poor that radiator is generally positioned at the outside so that LED cylindrical lamp radiating effect of cylindricality PC cover, therefore affects use power and the life-span of LED cylindrical lamp, has also limited applying of LED cylindrical lamp.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes the built-in LED cylindrical lamp of a kind of radiator, can strengthen lighting power, improves radiating effect.
For achieving the above object, the utility model proposes the built-in LED cylindrical lamp of a kind of radiator, comprise cylindricality PC cover, bonnet, power supply, radiator, lamp holder and with emitting led aluminium base, described power supply is arranged in the inner chamber of bonnet, lamp holder is connected to the end of bonnet, described cylindricality PC cover and radiator are all fixed on the end face of middle plate, radiator is arranged in the inner chamber of PC cover, described radiator has at least 8 sides, is fixed on the side of described radiator with emitting led aluminium base.
As preferably, the bottom of described cylindricality PC cover is provided with buckle, and cylindricality PC cover is fixed on middle plate through buckle.
As preferably, the top of described cylindricality PC cover is provided with PC plug, and the bottom centre of PC plug is provided with jut, and described jut is embedded in radiator.
As preferably, on the top end face of described radiator, be provided with aluminium base.
As preferably, described lamp holder is screw lamp holder.
The beneficial effects of the utility model: the utility model is fixed to cylindricality PC cover on bonnet by middle plate, avoided power supply in bonnet directly to contact with aluminium base, convenient heat radiation, aluminium base has not only effectively improved heat dispersion of the present utility model after being fixed on a plurality of sides of radiator, increases the service life, and strengthened lighting power, compared with prior art, the utility model radiating effect is strong, high-power advantage.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
