Abstract

The invention discloses an LED low-voltage lamp tube. The LED low-voltage lamp tube is characterized in that an LED lighting slab (3) is mounted in a position at the upper part of a tube body (1); a DC low-voltage constant-current power supply appliance (2) is arranged between the LED lighting slab (3) and the tube body (1); the incoming line of the power supply appliance (2) is connected to a low DC safe voltage of 6V, 12 V, 24 V or 36 V through the incoming line of the LED low-voltage lamp tube; the outgoing line of the power supply appliance (2) is connected with the LED lighting slab (3); a strip-shaped concave lens (4) is mounted below the LED lighting slab (3) and can perform the function of diverging rays; the concave lens (4) with an appropriate diopter can enable the maximum deviation of diverged rays on two sides of the plane of the normal line of the concave lens (4) to be within the range of 45-85 degrees from the plane. The tube body (1) of the LED low-voltage lamp tube is semicircular; a group of clamping grooves I is arranged outside the tube body (1) and used for fixing a semicircular frosted lamp shade (5); a group of clamping grooves II inside the tube body (1) used for fixing the LED lighting slab (3); another group of clamping grooves III inside the tube body (1) is used for fixing the strip-shaped concave lens (4); the internal and external surfaces of the tube body are both in dark color; the back of the LED lighting slab (3) is also in dark color. Therefore, the LED low-voltage lamp tube is safe to use and easy to popularize in classrooms, workshops and markets, and has the advantages of safe use, good radiating effect, good illuminating effect.

Description

A kind of LED low pressure fluorescent tube

Technical field

The present invention relates to a kind of LED low pressure fluorescent tube.

Background technology

Although existing LED illuminating lamp tube has the advantage of high-efficient energy-saving environment friendly longevity in the market, but be all 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-supplying device and power, belong to dangerous power voltage supply, and body is white aluminium section bar, radiating effect is poor, and the illuminating effect that causes of the optical characteristics of the narrow angle of LED emission of light height boundling is not good in addition, thus increased the LED fluorescent tube in the classroom, the difficulty promoted of workshop, market illumination.

Summary of the invention

The purpose of this invention is to provide the power supply of a kind of use low-voltage direct safe voltage, use 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 invention fluorescent tube includes body, the LED luminous plaque is arranged in the LED luminous plaque draw-in groove of body top, dc low-voltage constant current-supplying device is placed between LED luminous plaque and 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.

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

Described LED low pressure fluorescent tube, body are 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 separately has group leader's bar shaped concavees lens draw-in groove to be used for fixed length bar shaped concavees lens, and the body surfaces externally and internally is all made dark color.

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

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

Connect 6V or 12V or 24V or 36V low-voltage direct safe voltage during due to LED low pressure lamp works of the present invention, power to the LED luminous plaque through dc low-voltage constant current-supplying device, thereby use safety; The object darker according to surface color more easily absorbs heat, and the physics principle of the easier outside radiations heat energy of object that surface color is darker, dark color is all made at the surfaces externally and internally of the body of LED low pressure fluorescent tube of the present invention and the back side of LED luminous plaque, has greatly strengthened the heat radiation of fluorescent tube; Below adding LED luminous plaque of the present invention, adaptive strip concavees lens are installed, light for the luminous height of LED narrow angle boundling is similar to parallel rays, concavees lens can be effectively the concentrated light alignment normal both sides of LED luminous plaque are dispersed and the maximum deviation of divergent rays in the scope at both sides, concavees lens normal plane of living in 45° angle～85 ° of angles, add that the semicircle frosted lampshade of installing on the lamp body of concavees lens belows 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.
