Description

A kind of LED fluorescent tube

Technical field

The utility model relates to a kind of LED lighting, particularly a kind of LED fluorescent tube.

Background technology

Now at home lighting generally adopts tengsten lamp and fluorescence as light source, because that these light sources have is cheap for manufacturing cost, low price and luminosity advantages of higher occupy the main flow of illumination at home always.But, tengsten lamp belongs to heat to illuminator, electric energy is luminous after being heated to tungsten filament more than 2000 ℃, electric energy is converted into heat energy earlier and is converted into luminous energy again, in this process, 5% the electric energy of only having an appointment is converted into luminous energy, and other energy major part slatterns with the form of heat energy, and its energy utilization rate is extremely low; Moreover tungsten filament can consume under the condition of high temperature in volatilization, when the tungsten filament bulb that volatilizees has totally also been died, so relatively shortly have only about 5000 hours its service life.And fluorescent lamp belongs to gas-discharge lamp, charges into mercuryvapour in fluorescent tube, and mercuryvapour under high voltage ionization takes place, and sends the light of specific wavelength, and this light fluorescent material on the exciter lamp inside pipe wall again sends soft white light.Though fluorescent lamp increases than tengsten lamp on energy-conservation, but its most fatal shortcoming is to be filled with mercuryvapour in the fluorescent tube, as everyone knows, mercuryvapour is the poison gas that has that health is had serious harm, when the fluorescent tube mercuryvapour that breaks will be elegant comes out to second environmental pollution.So, in today of energy growing tension, develop the efficient height, more energy-conservation and house lighting environmental protection means a great beyond doubt and is related to the major issue of national economy.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of more energy-conservation, the house lighting that environmental protection and life-span are long, LED fluorescent tube.

The utility model solves above-mentioned technical problem by following technical proposals:

A kind of LED fluorescent tube, comprise great power LED, the lamp plate of great power LED is installed, the strip heat radiation backboard of lamp plate is installed, be installed in the strip transparent face mask of the described great power LED of covering on the heat radiation backboard and be installed in the Switching Power Supply that drives described great power LED on the heat radiation backboard.

The beneficial effects of the utility model are: because the utility model uses great power LED to replace the mercuryvapour of existing fluorescent tube as illuminating source, be equipped with devices such as heat sink and transparent face mask simultaneously and form the shell of fluorescent tube, make the utility model both have the function of use of fluorescent tube, advantages such as energy-saving and environmental protection that simultaneously have fluorescent tube again and lacked and long-life.

In addition, the utility model can also be further improved by the following technical programs:

The lateral surface of described heat radiation backboard is provided with radiating fin, and like this, under identical appearance and size, the heat radiation backboard has bigger area of dissipation, has better radiating effect.

Be provided with backplate between described transparent face mask and great power LED; backplate is provided with the hole, and described great power LED stretches out from described hole, and this backplate just can block and protect great power LED lamp plate and circuit structure thereof; make of the present utility model more attractive in appearancely, globality is better.

Described backplate is provided with reflecting coating, and the light of the scattering that great power LED can be made progress so down reflects, and improves the brightness of fluorescent tube.

Described great power LED has a plurality of, and a plurality of great power LEDs are divided into two groups, and a plurality of great power LEDs in each group are connected in series, and is in parallel between two groups; Described Switching Power Supply is two, is installed in the two ends of heat radiation backboard respectively, and each drives one group of great power LED, and two power supplys that open the light are controlled two groups of high-powered LED lamps respectively again, and reliability of products is better.

The specific embodiment

Referring to figs. 1 through Fig. 7, a kind of LED fluorescent tube, its light source is a great power LED 61, so-called in the industry great power LED 61 promptly is meant the LED of power greater than 1W, can select for use the higher LED of 1W to 10W or power as illuminating source according to illumination needs the utility model of reality, the quantity of great power LED can 10 to 30; Great power LED 61 is installed on the lamp plate 6, lamp plate 6 is installed on the heat radiation backboard 1 of strip again, lamp plate 6 is provided with circuit, one end of this circuit is connected with external power source, one end is electrically connected with the lamp base of great power LED 61 with lead, lamp plate 6 two ends have U type mouth 62, pass this U type mouth 62 with screw and just lamp plate 6 can be fixed on the heat radiation backboard; Lamp plate 6 can be as shown in Figure 4 split type, each great power LED is installed on the fritter lamp plate 6, again each fritter lamp plate 6 is respectively installed on the heat radiation backboard, also can be all-in-one-piece, a plurality of great power LEDs 61 promptly are installed on a lamp plate 6, again a whole piece lamp plate 6 are fixed on the heat radiation backboard 1; The transparent face mask 2 that a strip is also installed in the front of heat radiation backboard 1 covers described lamp plate 6 and great power LED 61 thereof, with protection great power LED 61 and other element, has the effect that beautifies product and strengthen the product globality simultaneously; Heat radiation backboard 1 and 2 of transparent face masks also are provided with the Switching Power Supply 5 that drives described great power LED 61, Switching Power Supply 5 is distributed in the two ends of fluorescent tube, on two end faces of fluorescent tube, also be provided with the plug 3 that connects external power source, like this, plug 3 is electrically connected with Switching Power Supply 5, Switching Power Supply 5 is electrically connected with lamp plate 6, and lamp plate 6 is electrically connected with great power LED on it.Because the utility model uses great power LED 61 to replace the mercuryvapour of existing fluorescent tube as illuminating source, be equipped with devices such as heat radiation backboard 1 and transparent face mask 2 simultaneously and form the shell of fluorescent tube, make the utility model both have the function of use of fluorescent tube, advantages such as energy-saving and environmental protection that simultaneously have fluorescent tube again and lacked and long-life.In addition, the utility model can also further be improved to:

The lateral surface of described heat radiation backboard 1 is provided with radiating fin 11, and like this, under identical appearance and size, heat radiation backboard 1 has bigger area of dissipation, has better radiating effect.

61 of described transparent face mask 2 and great power LEDs are provided with backplate 4; backplate 4 is provided with hole 41; described great power LED 61 stretches out from described hole 41; this backplate 4 just can block and protect great power LED 61, lamp plate 6 and circuit structure thereof; make of the present utility model more attractive in appearancely, globality is better.

Also can be provided with reflecting coating on the described backplate 4, the light that great power LED 61 makes progress scattering down can be reflected like this, improve the brightness of fluorescent tube.

Described great power LED 61 has a plurality of, and a plurality of great power LEDs 61 are divided into two groups, and a plurality of great power LEDs 61 in each group are connected in series, and is in parallel between two groups; Described Switching Power Supply 5 is two, is installed in the two ends of heat radiation backboard 1 respectively, and each drives one group of great power LED, controls two groups of high-powered LED lamps 61 respectively by two power supplys 5 that open the light, and reliability of products is better.
