Abstract

The utility model discloses an LED low-pressure tube. An LED luminescent plate (3) is disposed at the upper part of a tube body (1). A DC low-pressure constant current power supplier (2) is disposed between the LED luminescent plate (3) and the tube body (1). An inlet wire is connected to a 6V/12V/24V/36V low-pressure DC safety voltage through an inlet wire of the LED low-pressure tube, and an outlet wire is connected to the LED luminescent plate (3). The lower part of the LED luminescent plate (3) is provided with an elongated concave lens (4) for light divergence. The concave lens with appropriate dioptre is chosen, so that the largest deviation of the diverging light can be within the range of 45-85 DEG from two sides of a plane of the concave lens normal. The tube body (1) of the LED low-pressure tube is semi-circular. The outer side is provided with a set of slots used for fixing a semi-circular frosted lampshade (5). One set of the slots at the inner side is used for fixing the LED luminescent plate (3), the other set of the slots at the inner side is used for fixing the elongated concave lens (4). The inner and outer surfaces of the tube body are both made in deep color, and the back side of the LED luminescent plate (3) is made in deep color. The LED low-pressure tube is advantageous in that use is safe; effect of heat radiation is good; popularization of the LED low-pressure tube in classes, workshops and markets for illumination can be facilitated.

Description

A kind of LED low pressure fluorescent tube

Technical field

The utility model relates to a kind of LED low pressure fluorescent tube.

Background technology

Though existing LED illuminating lamp tube has the advantage of high-efficient energy-saving environment friendly longevity in the market, but all be that civil power alternating current 220V (some country is 110 volts) directly taps into lamp holder, change to the LED luminous plaque through the constant current charger and to power, belong to dangerous power voltage supply, and body is white aluminium section bar, radiating effect is poor, the illuminating effect that causes of the optical characteristics of the narrow angle of LED emission light height boundling is not good in addition, thus increased the LED fluorescent tube in the classroom, the difficulty promoted of workshop, market illumination.

The utility model content

The purpose of this utility model provides the power supply of a kind of use low-voltage direct safe voltage, uses safety, and good heat dissipation effect, good illumination effect, the LED low pressure fluorescent tube of be beneficial in the classroom, promoting in workshop, market illumination.

For achieving the above object, the described LED low pressure of LED low pressure fluorescent tube of the present utility model fluorescent tube includes body, the LED luminous plaque is installed in body top, in the LED luminous plaque draw-in groove, dc low-voltage constant current charger, place between LED luminous plaque and the body, its inlet wire connects 6V or 12V or 24V or 36V low-voltage direct safe voltage, and outlet connects with the LED luminous plaque.

Described LED low pressure fluorescent tube, below the LED luminous plaque, the concavees lens of one block length bar shaped are installed in the strip concavees lens draw-in groove of body, play divergent rays, cooperate concavees lens to the distance of LED luminous plaque, select the concavees lens of suitable Qu Guangdu as required, make the maximum deviation of divergent rays, in the scope at both sides, plane, concavees lens normal place 45～85 ° of angles.

Described LED low pressure fluorescent tube, body is semicircle, there is one group of frosted lampshade draw-in groove in the outside, be used for fixing semicircle frosted lampshade, the inboard has one group of LED luminous plaque draw-in groove to be used for fixed L ED luminous plaque, the inboard has group leader's bar shaped concavees lens draw-in groove to be used for fixed length bar shaped concavees lens in addition, and the body surfaces externally and internally is all made black.

Described LED low pressure fluorescent tube, black is made at the back side of LED luminous plaque.

Described LED low pressure fluorescent tube has semicircle frosted lampshade below concavees lens, be installed in the frosted lampshade draw-in groove on the body.

Owing to connect 6V or 12V or 24V or 36V low-voltage direct safe voltage during LED low pressure lamp works of the present utility model, give the power supply of LED luminous plaque through dc low-voltage constant current charger, thereby use safety; According to the more easy absorption heat of the more dark object of surface color, and the physics principle of the more easy outside radiations heat energy of object that surface color is more dark, black is all made at the surfaces externally and internally of the body of LED low pressure fluorescent tube of the present utility model and the back side of LED luminous plaque, has strengthened the heat radiation of fluorescent tube greatly; Add that LED luminous plaque of the present utility model below is equipped with adaptive strip concavees lens, light at the narrow angle of the luminous height of LED boundling is similar to parallel rays, concavees lens can effectively the concentrated light alignment normal both sides of LED luminous plaque be dispersed and the maximum deviation of divergent rays in the scope at both sides, concavees lens normal plane of living in 45～85 ° of angles, add that the semicircle frosted lampshade of installing on the lamp body of concavees lens below makes light more even through diffuse scattering, good illumination effect; So just realized use safety, good heat dissipation effect, good illumination effect, the purpose of be beneficial in the classroom, the illumination of workshop, market being promoted.
