Abstract

The utility model relates to a high brightness anti-glare LED fluorescent lamp tube comprising an aluminum substrate, an LED chip and an outer tube radiator. The outer side of the aluminum substrate is sheathed with a U-shaped milky white PC lampshade added with dispersant and fluorescent powder. The U-shaped milky white PC lampshade added with dispersant and fluorescent powder is internally provided with a constant current power source. The aluminum substrate tightly adheres to the outer tube radiator at the upper part of the aluminum substrate through a screw, the lower part of the aluminum substrate is welded with a plurality of LED chips connected with a circuit, and a reflecting membrane is arranged between the LED chips and the aluminum substrate. The lamp tube has the beneficial effects that the U-shaped milky white PC structure lampshade enlarges the irradiation angle of the whole lamp from the original 120 degrees to 140-160 degrees, and simultaneously, the reflecting membrane increases the brightness of PC appearance as well as the brightness of the lamp tube. The fluorescent lamp tube is characterized by better product reliability, energy saving, environment protection and long service life.

Description

A kind of high brightness glare prevention LED fluorescent tube

Technical field

The utility model relates to a kind of fluorescent tube, relates in particular to a kind of high brightness glare prevention LED fluorescent tube.

Background technology

Now at home lighting generally adopts tengsten lamp and fluorescent lamp 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, and electric energy is luminous after being heated to tungsten filament more than 2000 ℃, and 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 ionization under high pressure takes place mercuryvapour, 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 toxic gas 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.Along with deepening continuously of environmental protection and product safety idea, people have invented a kind of LED fluorescent lamp that adopts led lighting, this fluorescent lamp comprises the strip metal substrate that is provided with a plurality of LED and interlock circuit, the controller of gauge tap, the cylindric glass lamp that is installed in the lamp holder that the metal substrate both sides are connected with power supply and is set in this metal substrate outside.Diode can constantly produce heat in luminous process.The heat dispersion of this existing LED fluorescent lamp is relatively poor, and heat can not in time shed.Because the influence of the life-span of diode and performance received heat is bigger, thereby poor heat radiation can influence greatly the service life of LED fluorescent lamp, and the irradiation angle range of fluorescent tube own is limited.

The utility model content

The purpose of this utility model provides a kind of high brightness glare prevention LED fluorescent tube, to overcome the limited deficiency of irradiation angle range of existing LED fluorescent lamp heat radiation poor-performing, fluorescent tube.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of high brightness glare prevention LED fluorescent tube, comprise aluminium base, led chip and outer tube radiator, the outside of described aluminium base is arranged with the milky white PC lampshade that the U type adds diffusant and fluorescent material, the U type adds in the milky white PC lampshade of diffusant and fluorescent material and is provided with constant-current supply, described aluminium base is close on the outer tube radiator on aluminium base top by screw, the bottom of described aluminium base is welded with several led chips and links to each other with circuit, is provided with reflectance coating between described led chip and the aluminium base.

Beneficial effect described in the utility model is: the irradiating angle that the milky white PC structure of U type lampshade has enlarged whole lamp expands the 140-160 degree to from original 120 degree, increases the brightness of PC appearance, the brightness that has improved fluorescent tube with reflectance coating simultaneously, reliability of products is better, energy-conservation, environmental protection, the life-span is long.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of the described a kind of high brightness glare prevention LED fluorescent tube of the utility model embodiment.

Among the figure:

1, the U type adds the milky white PC lampshade of diffusant and fluorescent material; 2, aluminium base; 3, led chip; 4, constant-current supply; 5, reflectance coating; 6, outer tube radiator.

The specific embodiment

As shown in Figure 1, a kind of high brightness glare prevention LED fluorescent tube, comprise aluminium base 2, led chip 3 and outer tube radiator 6, the outside of described aluminium base 2 is arranged with the milky white PC lampshade 1 that the U type adds diffusant and fluorescent material, the U type adds in the milky white PC lampshade 1 of diffusant and fluorescent material and is provided with constant-current supply 4, described aluminium base 2 is close on the outer tube radiator 6 on aluminium base 2 tops by screw, the bottom of described aluminium base 2 is welded with several led chips 3 and links to each other with circuit, is provided with reflectance coating between described led chip 3 and the aluminium base 2.

The irradiating angle that the milky white PC structure of U type lampshade 1 has enlarged whole lamp expands the 140-160 degree to from original 120 degree, and the applying reflectance coating increases the brightness of PC appearance, the brightness that has improved fluorescent tube between led chip 3 and aluminium base 2 simultaneously, reliability of products is better, energy-conservation, environmental protection, the life-span is long.

Claims

1, a kind of high brightness glare prevention LED fluorescent tube, comprise aluminium base (2), led chip (3) and outer tube radiator (6), it is characterized in that: the outside of described aluminium base (2) is arranged with the milky white PC lampshade (1) that the U type adds diffusant and fluorescent material, the U type adds in the milky white PC lampshade (1) of diffusant and fluorescent material and is provided with constant-current supply (4), described aluminium base (2) is close on the outer tube radiator (6) on aluminium base (2) top by screw, the bottom of described aluminium base (2) is welded with several led chips (3) and links to each other with circuit, is provided with reflectance coating between described led chip (3) and the aluminium base (2).
