Abstract
The utility model discloses a double-layer diffuse reflection LED (light-emitting diode) fluorescent lamp, which comprises a lamp tube, wherein a lamp base is arranged at each of the two ends of the lamp tube; an LED luminous body is arranged in the lamp tube; the lamp tube consists of an outer tube and a lining, which are parallel; the lining is shaped like a groove; the two groove sides of the lining are connected with the inner wall of the outer tube to form bayonets respectively; the LED luminous body is arranged between the bayonets; the luminous surface of the LED luminous body faces the lining; the outer tube and the lining are made from glass. According to the lamp, the lamp tube is made from the glass, so that the brightness of the lamp can be better shown; temperature in the lamp tube is greatly reduced, so that the service life of the lamp is effectively prolonged, energy resources are saved, and an illumination angle of the lamp also is enlarged; a frosted layer and a diffusing powder or fluorescent powder coating are arranged on the outer tube and the lining respectively, the shortcoming of glare produced by an LED lamp is overcome to ensure that light emitted by the lamp is softer and more uniform by the frosted layer, and ultraviolet rays leaked from the LED lamp can be converted into visible light by the diffusing powder of fluorescent powder coating.
Description
Technical field
The utility model relates to LED lamp field, is specifically related to a kind of double-deck diffuse reflection LED fluorescent lamp.
Background technology
The LED fluorescent lamp be a kind of brightness higher than traditional fluorescent lamp, and power is far below the environment-friendly and energy-saving lamp of traditional fluorescent lamp, have start fast, power is little, without stroboscopic, be not easy to occur the characteristics of visual fatigue.The fluorescent tube of existing LED fluorescent lamp is comprised of PC translucent cover and aluminium radiator fin, pearl is arranged in fluorescent tube the LED lamp, due to PC material light transmittance and thermal conductivity factor lower, the light that in the fluorescent tube of this structure, LED lamp pearl sends is stranded in fluorescent tube greatly, cause the brightness of light fixture not maximize, the fluorescent tube internal temperature is higher simultaneously, must be by the aluminium radiator fin distribute heat, the temperature of light fixture aluminium radiator fin when continuous firing reaches 70 ~ 100 ℃, not only affect the service life of light fixture but also waste energy, the irradiating angle of light fixture has also been dwindled in the existence of aluminium radiator fin simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of double-deck diffuse reflection LED fluorescent lamp, PC translucent cover light transmittance and the thermal conductivity factor that can solve existing LED fluorescent lamp are lower, the brightness of light fixture does not maximize, in fluorescent tube, temperature is high simultaneously, the problem that not only affects light fixture service life but also waste energy.
The utility model is achieved through the following technical solutions:
Double-deck diffuse reflection LED fluorescent lamp, comprise fluorescent tube, described lamp tube ends is respectively equipped with lamp holder, be provided with the LED illuminator in described fluorescent tube, described fluorescent tube is comprised of parallel outer tube and liner, and described liner is grooved, and two trough rims of described liner are connected to form bayonet socket with the inwall of outer tube respectively, described LED illuminator is arranged between bayonet socket, and the light-emitting area of described LED illuminator is towards liner; Described outer tube and liner are made by glass.
The further improvement of the utility model scheme is that the trough rim of described liner is connected with outer tube wall by transparent binder.
The further improvement of the utility model scheme is, the inside and outside wall of the outer wall of outer tube and liner is respectively equipped with frosted layer, and the inwall of described outer tube is provided with fluorescent material or spread powder coating.
The further improvement of the utility model scheme is that the granularity of described fluorescent material or spread powder is three layers.
The further improvement of the utility model scheme is that the cross section of described outer tube is circle or polygon or abnormity.
The further improvement of the utility model scheme is that the cross section of described liner is arc or polygon or abnormity.
The further improvement of the utility model scheme is, described outer tube and interior backing simultaneously form cavity in this of notch.
The cross sectional shape of outer tube cross sectional shape of the present utility model and liner can any combination.
The utility model advantage compared with prior art is:
One, adopt light transmittance and thermal conductivity factor higher than the glass manufacture fluorescent tube of PC material, greatly reduce the light amount that is reflected back lamp interior, the brightness of light fixture is better represented;
Two, the temperature in fluorescent tube significantly reduces, and does not need to use aluminium radiator fin, has both effectively extended the service life of light fixture, has saved again the energy, has also enlarged the irradiating angle of light fixture, has reduced weight and the manufacturing cost of light fixture simultaneously;
Three, by outer tube and liner, frosted layer and spread powder or fluorescent coating being set respectively, the diffusing characteristic diffuser of frosted outer wall can solve the defect that the LED lamp produces dazzle, the light that light fixture is sent is softer, even, and the ultraviolet ray that spread powder or fluorescent coating can be revealed the LED lamp is converted into visible ray, the while double-decker has also overcome the frosted outer wall and easily has been corroded and then affects the light fixture defect in service life.
