Abstract

An LED lamp tube with a heat dissipation plate frame comprises an LED lamp tube body and the heat dissipation plate frame. According to the LED lamp tube, a lamp holder with LED lamp beads is directly installed on an aluminum substrate. The heat dissipation plate frame is composed of a heat dissipation plate and arc-shaped heat dissipation frames. The arc-shaped heat dissipation frames comprise inner frame bodies and outer frame bodies, and the inner frame bodies and the outer frame bodies are all installed on the back of the heat dissipation plate. Frame pins of the inner frame bodies penetrate through the heat dissipation plate and the aluminum substrate to directly make contact with the lamp holder, and frame pins of the outer frame bodies penetrate through the heat dissipation plate to directly make contact with the aluminum substrate. The aluminum substrate adheres to the heat dissipation plate through silica gel. The LED lamp tube has the advantages that the inner frame bodies of the arc-shaped heat dissipation frames are installed below the lamp holder provided with the LED lamp beads which are heated in a centralized mode, and therefore heat generated by the LED lamp beads can be directly rapidly dissipated to the heat dissipation frames through the structural characteristic of the inner frame bodies; due to the fact that the dense heat dissipation frames are installed on the heat dissipation plate of the lamp tube, the heat dissipation area is greatly increased, airflow easily flows, heat can be effectively and rapidly dissipated, and the heat dissipation effect is improved.

Description

The LED fluorescent tube of band heat radiation grillage

Technical field

The utility model belongs to LED technical field of lamps, particularly a kind of LED fluorescent tube with heat radiation grillage.

Background technology

The same with other light source, semiconductor light emitting diode (LED) also can produce heat during operation, and how much it depends on overall luminous efficiency.Power up outside under energy, the radiation recombination generation electroluminescent in electronics and hole, near the light radiating PN junction also needs just can arrive at the external world through the semiconductor medium of chip itself and encapsulation medium.Comprehensive electric current injection efficiency, radioluminescence quantum efficiency, chip exterior light take out efficiency etc., and finally probably only having the input electric energy conversion of 30-40% is luminous energy, and the energy of all the other 60-70% mainly transforms heat energy with the form of the lattice vibration of non-radiative compound generation.

In general, whether the work of LED lamp is stable, quality quality, and most important with lamp body heat radiation itself, the heat radiation of the high-brightness LED lamp on market, usually adopts natural heat dissipation, and effect is unsatisfactory.The LED light fixture that LED light source is made, is made up of LED, radiator structure, driver, lens, and therefore heat radiation is also a part and parcel, and its luminous efficiency declines along with the rising of environment temperature, so the heat radiation of LED is extremely important; The efficiency of power supply is high, and its dissipation power is little, just little in light fixture internal heat generation amount, has also just reduced the temperature rise of light fixture, can delay the light decay of LED; If LED can not finely dispel the heat, its life-span also can be influenced.

At present, the heat dissipating method of LED mainly contains aluminium radiating fin, increases area of dissipation with aluminium radiating fin as a part for shell; Heat-conducting plastic shell, uses LED insulating radiation plastics substitution of Al alloy to make radiator; Surface emissivity radiating treatment, smears heat loss through radiation paint, and heat is taken away to lamp housing surface with radiation mode; Air fluid mechanics, utilizes lamp housing profile, produces convection current air; Fan, inner with long-service life high-efficiency fan reinforcement heat radiation at lamp housing; Heat pipe, is transmitted to shell radiating fin by heat by LED chip; Liquid ball bubble, is filled into transparency liquid higher thermal conductivity in lamp body ball bubble; Utilize lamp holder, as screw socket, have the lamp holder heat radiation of larger metal surface; These methods are each has something to recommend him, can both solve some problems, but have limitation.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of LED fluorescent tube that radiating fin is changed into intensive heat radiation rack, utilizes heat dissipation characteristics and the structure of numerous arc bars, and increasing heat radiation area and the circulation that contacts air-flow, to comprehensively improve radiating efficiency.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is a kind of LED fluorescent tube with heat radiation grillage, comprises LED fluorescent tube and heat radiation grillage, it is characterized in that described LED fluorescent tube is that the lamp socket that LED lamp pearl has been installed is directly installed on aluminium base; Described heat radiation grillage is made up of heat sink and arc heat radiation rack, arc heat radiation rack divides Inner frame and outrigger, be installed on the back side of heat sink, wherein the frame of Inner frame is worn heat sink and is directly contacted with lamp socket with aluminium base, and the frame of outrigger is worn heat sink and directly contacted with aluminium base; Bonding by silica gel between aluminium base and heat sink.

When use, first the heat on lamp socket is transmitted on the Inner frame of aluminium base and arc heat radiation rack simultaneously, and the heat on aluminium base can be transmitted on heat sink and distribute by extraneous air-flow through silica gel again; Another part heat on aluminium base and heat sink can be transmitted to again on the Inner frame and outrigger of arc heat radiation rack simultaneously, then distributes by extraneous air-flow; So greatly increase area of dissipation and air-flow can easily be flowed, can make heat effectively and rapidly distribute.

The beneficial effects of the utility model are in LED lamp pearl, to be heated the Inner frame of arc heat radiation rack is installed below more concentrated lamp socket, the heat that can utilize like this architectural characteristic of Inner frame directly LED lamp pearl to be produced is dispersed into rapidly on heat radiation rack, owing to having installed intensive heat radiation rack on the heat sink of fluorescent tube, greatly increase area of dissipation and air-flow is easily flowed, can make heat effectively and rapidly distribute, improve radiating effect; The utility model is simple in structure, with low cost, is applicable to large-scale popularization.
