Abstract
The utility model relates to a hollow heat-radiation light-emitting diode (LED) bulb lamp. The hollow heat-radiation LED bulb lamp comprises a lamp holder, a plastic structural component, a heat radiator, an aluminum base board, LED lamp beads, a lampshade and a power supply, wherein the plastic structural component is connected to the lamp holder; the heat radiator is connected to the plastic structural component; the aluminum base board is connected to the heat radiator; the LED lamp beads, the lampshade and the power supply are arranged on the aluminum base board; a hollow heat radiation channel is formed in the heat radiator; an upper port and a lower port are formed in the heat radiation channel; and the aluminum base board is connected to the upper port of the heat radiator. The hollow heat radiator is arranged, so that the heat radiation effect of the LED lamp beads is improved, and the hollow heat radiator of the bulb lamp is relatively high in power.
Description
Technical field
The present invention relates to lighting technical field, particularly relate to a kind of hollow type heat-dissipating LED ball bulb lamp.
Background technology
The LED bulb lamp is the Novel energy-saving lamp that substitutes conventional incandescent, and it is better than traditional illuminating product in principle of luminosity, energy-saving and environmental protection aspect.High speed development along with the LED lighting engineering, the energy-saving effect of LED bulb lamp has reached very high degree, in equal luminous flux situation, energy consumption dropped to incandescent lamp 1/8 and electronic energy-saving lamp 1/2, be trend of the times so the LED illuminating product replaces traditional illuminating product.
At present, LED ball bulb lamp structure on the market mostly is: aluminium base contacts with radiator, is screwed to be locked on the radiator again, and such fixed form easily causes the point discharge of screw, is difficult to the high pressure resistant test by 4000V; And aluminium base contacts with radiator, dispels the heat by the mode of radiator and cross-ventilation heat exchange again, and aluminium base is closed in radiator inside, namely improves radiating effect by the method that increases the radiator exterior surface area at most, cures the symptoms, not the disease.Aluminium base and power supply all are closed in radiator inside, and the heat that produces during the work of LED lamp pearl raises the power work temperature, has a strong impact on the life-span of electronic devices and components, so that power supply lost efficacy prior to LED lamp pearl.Therefore, along with the development of LED technology, the light efficiency of LED lamp pearl progressively improves, and the LED bulb lamp is towards the future development that substitutes traditional 60W even 100W incandescent lamp, but clearly, and present existing heat dissipation technology has restricted the development of high brightness, high wattage bulb lamp.
Summary of the invention
The purpose of this utility model provides a kind of hollow type heat-dissipating LED ball bulb lamp.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of hollow type heat-dissipating LED ball bulb lamp, comprise lamp holder, be connected to plastic cement structural member on the described lamp holder, be connected to radiator on the described plastic cement structural member, be connected to aluminium base on the described radiator, be arranged on LED lamp pearl, lampshade and power supply on the described aluminium base, described radiator has the heat dissipation channel of a hollow, described heat dissipation channel has upper port, lower port, and described aluminium base is connected to the upper port place of described radiator.
Preferably, described plastic cement structural member extends to upper port from the lower port of described heat dissipation channel, and described aluminium base fixes by connector and described plastic cement structural member.
Preferably, the contact portion of described aluminium base and described radiator fits by heat-conducting silica gel sheet.
Preferably, described power supply is arranged on the bottom of described plastic cement structural member, and described power supply is connected by wire with described aluminium base.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model has improved the radiating effect of LED lamp pearl by the radiator of hollow type is set, and makes the radiator of this product hollow type can accomplish larger power.
