Abstract
The utility model discloses an LED (light-emitting diode) roadway lamp. A shell (1) is cylindrical; the closed end of the shell (1) is provided with a lamp shade (2), and the opened end of the shell (1) is sealed by a wiring end cover (3); radiating ribs (1a) are axially distributed on the outer surface of the shell (1); a circuit component (4) is arranged in a cavity between the shell (1) and the wiring end cover (3); the lamp shade (2) is internally provided with an LED light source (5) and a conical reflecting cover (6) which are respectively fixed on the end surface of the closed end of the shell (1); and the LED light source (5) is positioned at the center of the conical reflecting cover (6). In the LED roadway lamp, the structure is simple, the design is unique, the installation is convenient, direct contact of the LED light source and the shell greatly improves the radiating effect, a light source on the LED light source is provided with the conical reflecting cover so as to lead light irradiated to be more uniform and further reduce blind areas; and the assembly and disassembly of the whole shell, the lamp shade and a lamp head are very convenient, and the sealing effect is also good.
Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of mining LED tunnel lamp.
Background technology
At present, traditional tunnel lamp generally adopts incandescent lamp or common energy-saving lamp, incandescent lamp is approximately 1000 hours service life, common energy-saving lamp is generally about 3000 hours service life, service life is shorter, need the frequent light fixture of changing, this not only makes troubles to mine lighting, and it exists great potential safety hazard to the more important thing is, explosive atmosphere inflammable in the face of the down-hole.LED has characteristics such as light efficiency height, shock-resistant, anti-vibration as the novel light-emitting utensil, particularly used in a large number under the overall background of energy-conserving and environment-protective advocating, but LED tunnel lamp and has been ignored the thermal diffusivity of led light source owing to mostly mainly consider sealing.The present LED tunnel most heat dispersion of lamp is bad, also has defectives such as range of exposures is little, the blind area is big simultaneously.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of shines evenly, the LED tunnel lamp of good heat dissipation effect.
The technical solution of the utility model is as follows: a kind of LED tunnel lamp, comprise housing, its key is: described housing is cylindric, described housings close end is equipped with lampshade, this shell nozzle end is by the wiring end cap seal, described housing outer surface axial distribution has the heat radiation rib, in the cavity between described housing and the wiring end cap circuit unit is installed, led light source and taper reflection shield are installed in the described lampshade, described taper reflection shield and led light source all are fixed on the housings close end end face, and this led light source is positioned at taper reflection shield central authorities.Led light source directly is fixed on the housing, and housing is directly derived the heat of the luminous generation of LED, and the housing outer surface axial distribution has the heat radiation rib can increase area of dissipation, has further improved the thermal diffusivity of whole LED tunnel lamp.Led light source is provided with the taper reflection shield, has enlarged illumination range, has reduced the blind area.
Above-mentioned wiring end cap both sides are provided with the wiring mouth, and electric wire is entered in the housing then by stifled pad sealing by the wiring mouth.Above-mentioned lampshade is a hemispherical, this lampshade edge outward flanging, and the flange of described lampshade is pushed down by screw by trim ring and is fixed on the housing.This setting is at Minepit environment, requires under the situation of good airproof performance set.
Beneficial effect: the utility model is simple in structure, design is unique easy for installation, and led light source directly contacts with housing and promoted radiating effect greatly, and light source is provided with the taper reflection shield and makes that to shine the light that comes out more even on the led light source, has reduced the blind area; The assembling of whole housing and lampshade and lamp holder and dismantle very conveniently, sealing effectiveness is also fine.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of LED of the utility model tunnel lamp, form by housing 1, lampshade 2, wiring end cap 3, circuit unit 4, led light source 5, taper reflection shield 6, stifled pad 7 and trim ring 8, described housing 1 is cylindric, described housing 1 blind end is equipped with lampshade 2, lampshade 2 is a hemispherical, these lampshade 2 edge outward flangings, and the flange of described lampshade 2 is pushed down by screw by trim ring 8 and is fixed on the housing.Led light source 5 and taper reflection shield 6 are installed in the described lampshade 2, and described taper reflection shield 6 and led light source 5 all are fixed on the housing 1 blind end end face, and this led light source 5 is positioned at taper reflection shield 6 central authorities.Housing 1 openend is by wiring end cap 3 sealing, and wiring end cap 3 is fixed by screw between the housing 1.Described housing 1 outer surface axially is evenly distributed with heat radiation rib 1a, in the cavity between described housing 1 and the wiring end cap 3 circuit unit 4 is installed.Described wiring end cap 3 both sides are provided with wiring mouth 3a, and electric wire is entered in the housing 1 then by stifled pad 7 sealings by wiring mouth 3a.Wiring mouth 3a outer end is provided with wire casing 9, and electric wire is positioned at wire casing 9 to be pushed down by tension disc 10, and wiring end cap 3 end faces are provided with suspension ring 11.
Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression, such conversion all falls within the protection domain of the present utility model.
