Abstract

The utility model relates to a lighting lamp which adopts an LED lamp as a lighting carrier, namely, an LED lighting tube used for illumination. Currently, lighting lamps mostly adopt incandescent bulbs or fluorescent lights as the light source, which have certain defects in luminous efficiency, power consumption and service life, and currently, LED fluorescent lights are studied and still have the structural problems in heat dissipation, strength and rigidity. The LED lighting tube consists of a light bar, a light-permeable shell and choke plugs, which are fixed on a lamp body; the light bar comprises an LED fixed on an aluminium baseplate and is adhered on the lamp body; a light reflective plate is buckled on the lamp body; the light-permeable shell is inserted on the lamp body; and the choke plugs are respectively inserted at two ends of the lamp body. The LED lighting tube has good heat dissipation effect, the LED can work for a long time under the environment temperature of 16-20 DEG C, and the temperature at the surface of the lamp body 2 is below 32 DEG C, thus reaching the industrial standard. Experiments show that the problem of deformation of the lamp body is solved when the lamp body is at different lengths of 0.6-3m. The LED lighting tube is widely applicable in various illumination fields.

State Intellectual Property Office has announced a kind of " LED lighting circuit " patent on July 30th, 2008, application (patent) number: CN200720081257.X, basic structure is to comprise rectification circuit and regulating circuit, form bridge rectifier with 4 commutation diodes in the rectification circuit, an ac input end of bridge rectifier is provided with a current limliting decompression capacitor C1 and protective resistance R1, current limliting decompression capacitor C1 and protective resistance R1 parallel connection; The output of bridge rectifier is connected with main pressure regulator resistance R 2, filter capacitor C2, current limliting dropping resistor R3, a plurality of LED series connection, and current limliting dropping resistor R3 and a plurality of LED series connection group are to be connected in series, and forms R3LED series connection group; R3LED series connection group, main pressure regulator resistance R 2, these 3 parts of filter capacitor C2 are connected in parallel on the output of bridge rectifier.

Three, summary of the invention

The purpose of this utility model provides a kind of illuminating LED spot, arrives LED illuminating lamp luminous efficiency height, and intensity, rigidity and radiating effect can both satisfy the purpose that the safe handling of all lengths torch lamp requires., also can satisfy requirements of different users, save the energy more, longer service life, colour rendering index is near daylight, and is not mercurous pollution-free, can be widely used in indoor many places.

The utility model technical solution scheme is: the illuminating LED spot is fixed on the lamp body by striation, diffuser and plug to be formed, wherein striation evenly is fixed on the aluminium base by LED and forms, the striation bottom surface is adhesively fixed in the section bar lamp body central channel, the reflector that has card base snaps onto on the lamp body with bayonet arrangement, through hole correspondence uniform on its reflector is passed uniform LED, diffuser is plugged on the lamp body, the lamp body two ends plug of pegging graft respectively.

The technical scheme that its technical problem that solves the utility model adopts also has:

Described illuminating LED spot is characterized in that: each V-shaped groove of section bar lamp body section both sides that can dispel the heat is downward groove in the middle of two V-shaped grooves, and two V-shaped grooves are combined to form reinforcement, and lamp body and striation are formed the integral heat dissipation body.

Described illuminating LED spot is characterized in that: the section bar lamp body that can dispel the heat vertically has the ripple tooth of heat radiation, and lamp body and striation are formed the integral heat dissipation body.

Advantage of the present utility model and effect:

1, on probation through manufacturing experimently, compare with background technology, under the identical condition of illumination, power consumption is about 1/10 of incandescent lamp, 1/4 of fluorescent lamp, energy-saving effect highly significant.

2, LED is a semiconductor devices, and is not mercurous pollution-free, environmental protection.

3, working life was generally 50,000 hours, was about 50 times of incandescent lamp bulb, was about 20 times of fluorescent lamp.

4, owing to adopt LED as light emitting source, colour temperature is near daylight, colour rendering index height, good visual effect.

5, LED adopts the DC driven mode, does not have any flickering, has avoided the injury of other illuminating lamp to human eye.

6, good heat dissipation effect, under environment temperature-10-35 ℃, LED works long hours, and guarantees that LED worked 50,000 hours, and light decay is less than 30% of initial value.

7, owing to adopt LED as light emitting source and frosted diffuser, colour temperature is near daylight, colour rendering index height, good visual effect.

The section bar lamp body that 8, can dispel the heat has been owing to adopted curved longitudinal ripple tooth or the section of having of V-shaped groove or other shapes such as section bar lamp body section to be T font, U font, W font, Π font can to have the reinforcement intensity and the stiffness of longitudinal ripple tooth simultaneously better, in experiment, solved lamp body under all lengths as the indeformable problem of 0.6-3 rice length.
