Abstract

The utility model discloses a high-power light emitting diode (LED) lamp tube. The high-power LED lamp tube comprises a lampshade, a plug, a substrate, and LED lamps and a radiating module which are respectively arranged on the front surface and the back surface of the substrate, wherein a power supply drive module is arranged on the radiating module; a lens is arranged out of each LED lamp; each lens is provided with a symmetric composite curved surface; when the LED lamps emit light rays, the light rays are reflected and refracted repeatedly on the composite curved surface; the included angle between the light rays ahead can reach 180 DEG, so that hemispherical light rays can be emitted and uniform light spots appear; and therefore, light rays used for invalid lighting are reduced greatly, the efficacy of the LED lamp tube with the same power is nearly doubled compared with the conventional lamp tube, and moreover, the heat is reduced and the power consumption is reduced.

Description

A kind of great power LED fluorescent tube

Technical field

The utility model relates to a kind of lighting, is specifically related to a kind of great power LED fluorescent tube.

Background technology

In recent years, the great power LED fluorescent tube has obtained development fast, just progressively gets into the general lighting field.Compare with traditional incandescent osram lamp and fluorescent lamp; The LED fluorescent tube has that volume is little, caloric value is low, the advantage that power consumption is little, and can start by the low pressure low current; Reaction speed is fast and the ability high frequency time is operated, long service life, thereby the title of " green illumination light source " is arranged.

The problem that existing great power LED fluorescent tube mainly exists is: the LED lamp on the substrate be 360 ° luminous; But there is nearly 50% light to be used for invalid illumination; In the market, parking lot etc. needs the place of illumination on a large scale; Can only cause caloric value bigger through increasing the deficiency that fluorescent tube quantity remedies light, energy consumption be high.

The utility model content

The purpose of the utility model provides a kind of great power LED fluorescent tube that can send 180 ° of uniform lights at direction of illumination.

The utility model solves the technical scheme that its technical problem adopted: a kind of great power LED fluorescent tube; Comprise lampshade, plug, substrate and be arranged on the double-edged LED lamp of substrate and the heat radiation module; The heat radiation module is provided with electric power driving module; Described LED lamp is provided with lens outward, and described lens have the compound curved surface of symmetry.

Wherein, described substrate surface is provided with reflective membrane.

Further; Described compound curved surface comprise two juts being symmetrical set and with the depressed part of jut transition adjacency; Described jut is formed described curved surface and depressed part smooth connection by a hemisphere face and with the plane and the curved surface of hemisphere face smooth connection.

Further again; Described jut is seen from the side by a partial sphere and the transition face that symmetry is connected the partial sphere both sides and is constituted; The angle of described plane and installed surface is 60 ± 5 °, and the angle of described curved surface midpoint section and installed surface is 60 ± 5 °.

The beneficial effect of the utility model is: because the LED lamp is provided with the lens with symmetrical compound curved surface outward, luminous when the LED lamp, light repeatedly reflects in compound curved surface and reflects; Angle can reach 180 ° between the light in the place ahead, sends hemispheric light, uniform hot spot occurs; The light that is used for invalid illumination like this significantly reduces; The more traditional fluorescent tube effect of the LED fluorescent tube of equal-wattage promotes nearly one times, and the caloric value reduction, has saved power consumption.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

With reference to Fig. 1, Fig. 2 and shown in Figure 3, the utility model discloses a kind of great power LED fluorescent tube, comprise lampshade 51, plug 52, substrate 53 and be arranged on substrate 53 double-edged LED lamps 54 and heat radiation module 55; Heat radiation module 55 is provided with electric power driving module 56, and described substrate 53 surfaces are provided with reflective membrane 57, the described LED lamp 54 outer lens that are provided with; Described lens have the compound curved surface of symmetry, wherein, described compound curved surface comprise two juts 2 being symmetrical set and with the depressed part 3 of jut 2 transition adjacency; Described jut 2 is formed with curved surface 23 by a hemisphere face 21 and with the plane 22 of hemisphere face 21 smooth connections, described curved surface 23 and depressed part 3 smooth connections, further; Described jut 2 sees from the side by a partial sphere 41 and the transition face 42 that symmetry is connected partial sphere 41 both sides and constitutes that described plane 22 is 60 ± 5 ° with the angle of installed surface 1, and the angle of described curved surface 23 midpoint sections and installed surface 1 is 60 ± 5 °; Luminous when LED lamp 54, light gets in two juts 2, produces refraction and reflection; Total reflection takes place at depressed part 3 places in the light of part refraction once more, and in the space of distribution of light outside installed surface 1 that lens penetrate away, angle can reach 180 ° between the light at two ends; Send hemispheric light; Uniform hot spot occurs, the light that is used for invalid illumination like this significantly reduces, and the more traditional fluorescent tube effect of the LED fluorescent tube of equal-wattage promotes nearly one times; And the uniformity of hot spot improves greatly; And the caloric value reduction, saved power consumption, meet the trend of current light fixture environmental protection.

Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
