Abstract
The utility model discloses an effectively-radiating LED fluorescent lamp, comprising an aluminum radiating pipe (1) and a lamp shade (2), wherein the aluminum radiating pipe (1) is provided with a PCB substrate (3) which is provided with an LED chip (4). The effectively-radiating LED fluorescent lamp is characterized in that the inner wall of the aluminum radiating pipe (1) is provided with radiating fins (5); and the aluminum radiating pipe (1) is provided with radiating holes (6). The air can enter the pipe from the radiating holes at the two ends of the aluminum radiating pipe, and when the LED chip works, the generated heat is conducted onto the aluminum radiating pipe and the radiating fins by the substrate; as the radiating fins reasonably increase the contact area thereof with the air, the effectively-radiating LED fluorescent lamp can transfer the heat to the air rapidly, and then the heat flows from the radiating hole to form convection current, thus achieving the purpose of effectively reducing the temperature in the aluminum radiating pipe and realizing the best radiating effect.
Description
Technical field
The utility model belongs to the technical field of LED lighting, specifically is meant a kind of LED fluorescent lamp of efficiently radiates heat.
Background technology
At present, owing to use LED to have advantages such as brightness height, energy-saving and environmental protection, life-span length, be used widely in the room lighting field as the fluorescent lamp of light source.In order to reach the required illumination of room lighting, given play to LED daylight lamp energy-saving environment-friendly advantage, way is to arrange a large amount of LED in the LED fluorescent-lamp tube usually in the industry, enables to send enough amount of lumens.But this makes again, and temperature climbs up and up in the LED fluorescent tube.And the rising of temperature for LED, just means the aggravation of light decay, the shortening of light source life, and this is to run in the opposite direction with LED energy-saving and environmental protection, long original intention of life-span, so effectively heat radiation is the important technological problems that the LED fluorescent lamp need solve.
The utility model content
The purpose of this utility model is to provide a kind of LED fluorescent lamp that can effectively dispel the heat.
In order to address the above problem, the utility model provides a kind of heat dissipating method: the LED fluorescent lamp of efficiently radiates heat, comprise aluminium radiating tube and lampshade, be equiped with the PCB substrate on the aluminium radiating tube, the PCB substrate is provided with led chip, the inwall of described aluminium radiating tube is provided with radiating fin, and described aluminium radiating tube is provided with louvre.
Described radiating fin axially is provided with along the aluminium radiating tube.
Described radiating fin is at least two.
During the utility model work, air can enter in the pipe from the louvre at aluminium radiating tube two ends, the heat that produces during led chip work conducts on aluminium radiating tube and the radiating fin through substrate, because radiating fin has reasonably increased the contact area of itself and air, can be delivered to heat in the air apace like this, flow out from louvre again, form convection current, reach the purpose of temperature in effective reduction aluminium radiating tube, realized best radiating effect.The utility model is descended whole aluminium radiating tube temperature, effectively prolongs the LED fluorescent lifetime.Have advantages such as easily manufactured, low cost of manufacture in addition, have very strong practicality and promotional value.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the stereogram of the LED fluorescent lamp of efficiently radiates heat;
Fig. 2 is the cutaway view of the LED fluorescent lamp of efficiently radiates heat.
The specific embodiment
As shown in Figure 1 and Figure 2, the LED fluorescent lamp of efficiently radiates heat described in the utility model comprises aluminium radiating tube 1 and lampshade 2, installs power supply unit in the aluminium radiating tube 1.Be equiped with PCB substrate 3 on the aluminium radiating tube 1, PCB substrate 3 is provided with several led chips 4.The inwall of described aluminium radiating tube 1 is provided with radiating fin 5, can not influence the globality and the aesthetic property of LED fluorescent lamp like this, and described radiating fin 5 axially is provided with along aluminium radiating tube 1, and described radiating fin 5 is at least two.Described aluminium radiating tube 1 is provided with louvre 6, and described louvre 5 is arranged on the two ends of aluminium radiating tube 1, and described louvre 5 is at least two.Its concrete set-up mode is that the perforate quantity of louvre 5 is decided on the fluorescent lamp wattage level at one group of louvre 5 of LED fluorescent lamp aluminium radiating tube each perforate of two ends.
During work, the heat of led chip 4 luminous generations conducts to aluminium radiating tube 1 through substrate, air can enter in the pipe from the louvre at aluminium radiating tube 1 two ends, the heat that produces during led chip 4 work conducts on aluminium radiating tube 1 and the radiating fin 5 through PCB substrate 3, because radiating fin 5 has reasonably increased the contact area of itself and air, can be delivered to heat in the air apace like this, air flows out from louvre again, form convection current, reach the purpose that reduces temperature in the aluminium radiating tube.Temperature is reached an agreement outside can making the heat of radiation in pipe like this and managing, whole aluminium radiating tube temperature descended, effectively prolong the LED fluorescent lifetime, after tested, be under 28 ℃ the environment in temperature, using 1.2 meters 19 watts of LED fluorescent lamps being with radiating fin to test out its hull-skin temperature is 40 ℃, and not with the LED fluorescent lamp of radiating fin, temperature reduces by 5 ℃ than same model.Want＜85 ℃ requirement well below led chip PN junction central temperature.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
