Abstract
The utility model relates to an annular light emitting diode illuminating lamp, comprising a alloy-added aluminum shell 1, a plurality of light emitting diodes (LEDs) 2, a hollow cone-like circuit board 3, a transparent housing 4 and a DC plug assembly 5; wherein, an electrostatic proof earthing screw 6 and a set screw 7 are arranged on the shell; the DC plug assembly is connected with the hollow cone-like circuit board so that an external power can be inputted into the utility model. The LEDs are annularly distributed on the hollow cone-like circuit board; the intersection angle between the board plate of the hollow cone-like circuit board and the related bearing axis is sixty five degrees. In addition, the transparent housing is arranged on the housing via a claw and a card slot, protruding outward the shell surface. In addition to the advantages of a longer service life without flicker phenomenon of fluorescent lamp, the utility model has color temperature invariability in luminance regulation, as well as stepless adjustment capability for luminance brightness and excellent light focusing. Arranged in the shell via the claw and the card slot, the transparent housing is also protruding outward the shell surface; thus, the utility model can be easily taken out of the shell. Furthermore, with a good appearance as well as a simple and convenient lamplight focusing structure, the utility model is more particularly suitable to be arranged on a microscope for use as an illuminating lamp.
Description
Technical field
The utility model relates to a kind of lighting device, particularly a kind of annular LED illumination lamp.
Background technology
In the prior art, light emitting diode (LED) illuminating lamp is widely used on the light fixture such as traffic indication, directing light of automobile and advertisement screen demonstration with its long service life, flashless phenomenon, colour temperature does not change when regulating brightness, luminance brightness can 0 ~ 100% advantages such as adjusting.And the illumination that is used for instruments such as microscope all is to adopt light fixture such as incandescent lamp, daylight lamp.Its weak point be to use the life-span short, phosphere is arranged, colour temperature can change when regulating brightness, the luminance brightness adjustable extent is limited.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of annular LED illumination lamp that is used for Instrument Illumination such as microscope is provided.
The technical solution of the utility model is: annular LED illumination lamp comprises shell, light emitting diode, hollow truncated cone-shaped wiring board, transparent housing and DC plug assembly, the DC plug assembly is installed in the side of shell, light emitting diode circularizes and is distributed on the hollow truncated cone-shaped wiring board, hollow truncated cone-shaped wiring board is positioned at shell, the angle of its plate face and its endoporus axial line is the 10-80 degree, and transparent housing is installed on the shell.
On the outer of transparent housing claw is arranged, the draw-in groove that cooperates with the claw of transparent housing outer is arranged on the shell, transparent housing is installed on the shell by claw and draw-in groove and protrudes the shell plane.
The anti static grounding screw is installed on the shell.
Holding screw is installed on the shell.
The utility model is owing to adopt as above design, compared with prior art, advantage such as have the phosphere of long service life, fluorescence less lamp, colour temperature does not change when regulating brightness, but luminance brightness step-less adjustment, light focusing are good, transparent housing clamps in the enclosure by claw, and protrusion shell plane, the plastic, transparent cover is taken out and good looking appearance in shell easily, and the focusing structure of light is simple and convenient, is specially adapted to be installed in do the illuminating lamp use on the microscope.
