Abstract
The utility model discloses a transmission increasing LED lamp tube, which comprises a lamp tube, a circuit board with an LED array, lamp holders and a transmission increasing film. The lamp holders are arranged at two ends of the circuit board, and the transmission increasing film arranged on the inner wall of the lamp tube is a magnesium fluoride or calcium fluoride coating layer. The transmission increasing LED lamp tube reduces optical reflection of the inner wall of the lamp tube, can increase light transmittance of the lamp tube, and reduces requirements on lamp tube materials, thereby not only reducing production cost, but also decreasing the temperature inside the lamp tube to a certain extent.
Description
[technical field]
The utility model relates to the LED technical field, relates to a kind of anti-reflection type LED fluorescent tube in particular.
[background technology]
LED is favored by various fields more and more with its plurality of advantages, at lighting field, the LED electricity-saving lamp replaces the position of Halogen lamp LED and fluorescent lamp just gradually.Existing LED energy-saving lamp tube, its structure mainly include the led array in the Transparent lamp tube, fluorescent tube and the lamp socket of lamp tube ends, and led array generally all is arranged on the printed circuit board (PCB).In order to save cost, most of fluorescent tube adopts transparent plastic to be made more, but this fluorescent tube light transmittance is relatively poor.
[utility model content]
The purpose of this utility model is the deficiency at above-mentioned technology, a kind of anti-reflection type LED fluorescent tube is provided, and the utility model is provided with one deck anti-reflection film at tube inner wall, has not only improved the light transmittance of fluorescent tube, and can also reduce requirement to the fluorescent tube material, therefore also reduced production cost.
The utility model is to adopt following technical scheme to realize above-mentioned purpose: a kind of anti-reflection type LED fluorescent tube, include fluorescent tube, be provided with led array circuit board, be located at the lamp socket at circuit board two ends, it is characterized in that: be provided with anti-reflection film at tube inner wall.
Described anti-reflection film is a single or multiple lift.
Described anti-reflection film is magnesium fluoride or calcium fluoride coating.
Described fluorescent tube is transparent plastic tube or glass tube.
The beneficial effect that the utility model adopts above technical scheme to reach is: the utility model is provided with one deck anti-reflection film at tube inner wall, can reduce the reflective of tube inner wall, the light transmittance of fluorescent tube can not only be increased, the temperature in the fluorescent tube can also be reduced to a certain extent.
[description of drawings]
Accompanying drawing 1 is a structural representation of the present utility model.
Description of reference numerals: 1, led array; 2, circuit board; 3, fluorescent tube; 4, anti-reflection film; 5, lamp socket.
[specific embodiment]
For further setting forth the utility model 26S Proteasome Structure and Function, the utility model is elaborated below in conjunction with accompanying drawing and preferred embodiment:
As shown in Figure 1, the utility model is a kind of anti-reflection type LED fluorescent tube, include fluorescent tube 3, be provided with led array 1 circuit board 2, be located at the lamp socket 5 at circuit board 2 two ends, be provided with one deck magnesium fluoride anti-reflection film 4, the thickness of this anti-reflection film at fluorescent tube 3 inwalls.For saving cost, this fluorescent tube 3 is transparent plastics fluorescent tube.
Single layer anti reflective coating can only make the light of certain specific wavelength λ reduce reflection as far as possible, for other reverberation of close-spaced wavelength weakening in various degree arranged also, but not to reduce to the most weak, for typical CCD camera and visual optical instrument, often choose the most responsive wavelength X of eye=550nm as " control wavelength ", therefore, the magnesium fluoride coating layer thickness is 137.5nm in the present embodiment, so both can at utmost strengthen the light transmittance of human eye visible light.
Only the part of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; can not limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
