Abstract

An LED ceiling lamp comprises a light-emitting light tube, light tube-fixing holders, a lamp cover and an LED light source arranged in the light tube. The LED ceiling lamp is characterized in that: a group of cooling fans or computer radiating modules are arranged on the lamp cover and positioned at both ends of the light-emitting light tube; the LED light source in the light-emitting light tube is arranged on an internal tube with ventilating holes, and is provided with an internal power transformer, and the LED light source and the light-emitting light tube form a main light-emitting framework through internal connectors arranged on both ends of the internal tube. Since the internal and the external ventilating structures surrounding the light-emitting light tube are structurally formed, the heat dissipation problem of the LED ceiling lamp is effectively solved, and thereby the purpose of the design of the utility model is achieved.

Description

A kind of LED lamp affixed to the ceiling

Technical field

The utility model relates to a kind of LED light fixture, and especially a kind of LED lamp affixed to the ceiling with radiator belongs to the lighting class.

Background technology

In recent years since, constantly perfect along with the LED technology, the various performances of illuminating LED light fixture have had greatly progressive, more because the LED lighting has the factory director in service life, start-up time is short, energy-saving effect is remarkable, do not have ultra-violet radiation and advantages such as environmental pollution, safety in utilization height, approved widely, become the main flow of following energy-saving lamp.

But, because the LED lamp is photoelectric device, in its photoelectric conversion process, have only 15～25% electric energy to convert luminous energy to, remaining electric energy nearly all converts heat energy to, and the temperature of LED light fixture is raise.The existence of this phenomenon just, LED light fixture all can design radiator leaves the heat of LED light fixture.

Traditional " fluorescent lamp " is the widely used lighting of present user, in order in traditional illumination " fluorescent lamp ", to use led light source, present most of LED " fluorescent lamp " type light fixture, though its appearance and size is designed to traditional " fluorescent lamp " equally, but because led light source must be furnished with radiator, so present LED " fluorescent lamp " light fixture of releasing, the metal heat sink design is at the first half of light fixture in its radiator structure, and expose in air with the radiating effect that obtains and the led light source heat matches, though this radiator can play the thermolysis of led light source, but because radiator can not printing opacity, demifacet 180 degree cambered surfaces are luminous downwards to cause the LED fluorescent lamp tool, obviously, such LED " fluorescent lamp " can not reach or substitute the function of use of 360 ° of traditional omnibearing luminous fluorescent lamp tools fully.

Therefore, how to design and a kind ofly can meet the 360 degree alight tools that led light source heat radiation required, can guarantee again " LED fluorescent lamp ", just become a big problem of the sector research and development and manufacturing firm.

The utility model content

The purpose of the present utility model: being intended to propose a kind of LED lamp affixed to the ceiling with heat radiation function, effectively solving the replacement problem of LED light fixture and traditional fluorescent lamp, further improve the scope of application of LED " fluorescent lamp " light fixture, also is simultaneously that its outward appearance is beautiful more.

This LED lamp affixed to the ceiling comprises luminous lamp tube, lamp tube securing holder, lampshade and is arranged on the interior led light source of fluorescent tube that it is characterized in that: the cover body position, two ends that is positioned at luminous lamp tube on the described lampshade is provided with one group of radiator fan or computer radiating module.

Led light source in the described luminous lamp tube is arranged on the interior pipe of a band air vent, and led light source is furnished with the internal electric source converter, and forms luminous main truss by pipe two ends internal connector and luminous lamp tube in being arranged on.

Described led light source is dispersed on the body interior shutting according to the hexagonal angle degree.

Pipe is circular cylinder or equilateral triangle cylinder in described.

This LED lamp affixed to the ceiling according to above technical scheme proposition, by utilizing the flurorescent tube light-emitting mechanism of led light source abandoning tradition fluorescent tube, eliminate the pollution, the raising utilization rate of electrical that exist in application making that fluorescent material brought and the application, the heat energy that produces when utilizing the radiator reduction led light source of setting up in the lampshade luminous simultaneously, obviously this provides technical support to promoting the use of led light source.

The specific embodiment

This LED lamp affixed to the ceiling as shown in the figure, comprise luminous lamp tube 2, lamp tube securing holder 3, lampshade 5 and be arranged on the interior led light source 7 of fluorescent tube, it is characterized in that: the cover body position, two ends that is positioned at luminous lamp tube 2 on the described lampshade 5 is provided with one group of mini-fan 4 or computer radiating module.

Led light source 7 in the described luminous lamp tube 2 is arranged on the interior pipe 6 of a band air vent, and led light source 7 is furnished with internal electric source converter 9, and forms luminous main truss by the 6 two ends internal connectors 11 of pipe in being arranged on luminous lamp tube.

Described led light source 7 is dispersed on the body according to the hexagonal angle degree on interior pipe 6.

Pipe 6 is circular cylinder or equilateral triangle cylinder in described.

In the technique scheme, the inventor not only adopts the main electric light source of LED as " fluorescent lamp type " lamp affixed to the ceiling, simultaneously in order to solve heat dissipation problem, takes two technical measures:

The first is provided with mini-fan on the both sides of lampshade, reduces by air draft and looks for interior temperature; In practice, also can adopt radiating module habitual in the notebook computer.

It two is to settle the foundation design of led light source to become hollow cylindricality body, and air vent is set on body, internal electric source converter, internal connector, external power source connector that simultaneously again will be supporting with it be all formed the hollow type structure, make the fluorescent tube after the assembling form the cavity that two connects, the benefit of this structure is to be convenient to led light source and in time dispels the heat.

Therefore very structurally constitute the inside and outside ventilation and heat structure of two covers just because of the utility model, solve the heat dissipation problem of LED lamp affixed to the ceiling effectively, reach original intention of the present utility model around luminous lamp tube.
