Description

Ligthting lamp capable of wearing on forehead

Technical field

The utility model relates to a kind of low-power lighting that is worn on the forehead.

Background technology

Existing miner uses is worn over illuminating lamp on the forehead, because working environment and requirements of one's work, under pitch-dark dusty environment, carry out operation, not only brightness wants high, also will guarantee certain range of exposures, also will guarantee enough irradiation distances, make light source so often adopt powerful based on halogen bulb, so the illuminating lamp that the miner uses is relatively heavier, is the special lighting special use, the improper general lighting of doing routine work and study.

Summary of the invention

The purpose of this utility model provides a kind of low-power lighting that is worn on the forehead, and the local and in-plant illuminations of a kind of light and handy practicality, energy saving is provided for people's work, study, reading or inspection (as the inspection of ENT dept. in the medical treatment) etc.

Ligthting lamp capable of wearing on forehead of the present utility model (hereinafter to be referred as illuminating lamp) is worn structure by pedestal, light source and dress and is constituted; Pedestal is made of light source base and base, is connected by universal joint between light source base and the base; Light source base is the groove shape, and outlet wherein is housed, and can patch external power supply; Light source is loaded in the light source base and is electrically connected with outlet; Light source is white light-emitting diode (LED) or cold-cathode fluorescence lamp, also can be other general miniature bulb; It is to adorn cap shape or the banded structure that is worn on the forehead to this illuminating lamp that dress is worn structure, is connected with base bottom or both sides.

The cap-like structure that described dress is worn structure can be the cap (can not be with the brim of a hat) that various materials are made, and banded structure can be the belt that various materials (as plastics, leather, rubber, cloth, rubber band etc.) are made.

When the light source of the utility model illuminating lamp adopts white light-emitting diode, a plurality of white light-emitting diodes can be installed and connected in earlier on the circuit board, be installed in the light source base again.

Circular, oval, square, square or other shape of circle that the light source base of the utility model illuminating lamp and base can be done.

The light source base of the utility model illuminating lamp is owing to be the groove shape, so also have the effect of reflection shield, and except that can making reflective optically focused, the function that also has shading, usually the degree of depth that constitutes the groove of light source base generally is not less than the height of light source, make light source not expose light source base, the light of light source can not shine directly into user's eyes when guaranteeing to use, in order to avoid cause discomfort.

The light source of the utility model illuminating lamp adopts white light-emitting diode (LED) or cold-cathode fluorescence lamp.White light-emitting diode has that volume is little, brightness is high, and the light fixture heating less, the life-span is long, characteristics such as operating voltage is low, energy saving; Can be installed in a plurality of white light-emitting diodes on the light source base with pencil, and make it to focus on the about 30-50cm of the eyes visual field far away.Cold-cathode fluorescence lamp fluorescent tube caliber little (caliber can be made about the about 2mm of diameter), relative white light-emitting diode, (illumination can reach 25000CDm to its brightness height ²More than), big, the distance of the scope that can shine, it is few also to have heating and a stroboscopic, energy saving, characteristics such as the life-span is long can be made different shape according to the requirement of use again, thereby also be the perfect light sources of the utility model illuminating lamp.

The safe low-voltage DC that illuminating lamp of the present utility model can be converted to by the civil power of 110V/220V or provide power supply by dry cell or battery.Because the operating voltage of light emitting diode is low, is generally 3.6V, therefore, just can realize the brightness of light emitting diode is regulated by changing voltage method.When light source adopts cold-cathode fluorescence lamp, can directly adopt to be fit to the external power supply that cold-cathode fluorescence lamp uses, promptly earlier by the safe low-voltage DC of AC-DC circuit with the civil power conversion, the little magnitude of current high-frequency and high-voltage power supply of the safety that becomes through the DC-AC circuit conversion again; Because the used for cold cathode fluorescent lamp electric weight only needs several milliamperes, the high voltage of the so little magnitude of current remains safe to human body.

The light source of the utility model illuminating lamp can also adopt cold light film or other illuminator, does illumination or does the toy use.When doing the toy use, light source base can also be made different shape, and illuminator is also made the shape that is complementary thereupon, to increase entertainment effect.

Illuminating lamp of the present utility model is small and exquisite attractive in appearance, light practicality, safe in utilization, convenient, particularly owing to adopt white light-emitting diode (LED) or cold-cathode fluorescence lamp as light source, have that volume is little, brightness is high, heating less, the life-span is long, characteristics such as operating voltage is low, energy saving.The utility model illuminating lamp can be used as the part of general work, study, reading or inspection (as the inspection of ENT dept. in the medical treatment) etc. and illuminations closely.
