Abstract
The utility model relates to a light emitting diode camp lamp safety helmet, comprising a safety headpiece, a headlamp and a power supply, which is characterized in that the headlamp adopts a light emitting diode as a light source, a controlling circuit is arranged between the headlamp and the power supply, both the power supply and the controlling circuit are arranged inside the safety helmet, the controlling circuit can be a constant current source circuit or a constant voltage source circuit, the power supply can be chargeable battery. The light emitting diode camp lamp safety helmet has the advantages that the utility model adopts the light emitting diode with high brightness as light sources, which realizes the long service life, low power consumption, and high brightness of the light sources, improves the lighting evenness, adaptability of human eyes towards light wave and color temperature, and the stability of luminous intensity, moreover, the power supply can be charged for many times, and the integration of camp lamps and headpieces can reduce load on the miners and the influence of cables towards operations.
Description
Technical field
The utility model relates to a kind of mine lamp safety cap that has, particularly a kind of miner's lamp prepared from LED safety cap.
Background technology
Existing miner uses has the mine lamp safety cap, and its mine lamp mainly is the ore deposit bubble small electric bulb of soda acid battery type, and volume is big, Heavy Weight, illumination is low, service life is short, safety cap and battery are separate type, carry inconvenience, and cable connection is arranged, directly influence miner's work.
Summary of the invention
The purpose of this utility model has provided a kind of miner's lamp prepared from LED safety cap, mine lamp and safety cap that traditional miner uses have been solved, its mine lamp mainly is the small electric bulb mine lamp of soda acid battery type, volume is big, Heavy Weight, illumination is low, service life is short, safety cap and battery are separate type, carry inconvenience, and cable connection is arranged, directly influence the technical problem of miner's work.The utility model designs a kind of miner's lamp prepared from LED safety cap, comprise crash helmet, head lamp, power supply, it is characterized in that: it is light source that head lamp adopts light emitting diode, be provided with control circuit between head lamp and power supply, power supply and control circuit all are positioned at crash helmet inside, described control circuit can be a constant-current source circuit, also can be constant voltage power supply circuit, and described power supply adopts rechargeable battery.The utility model has the advantages that adopting high brightness LED is the lighting source of mine lamp, realized the uniformity of long-life, low-power consumption, high brightness, improvement illumination of light source and light wave colour temperature adaptability to human eye, luminous intensity is stable, and power supply can repeatedly charge, the mine lamp and the helmet are integrated, reduce the miner on one's body load and cable to the influence of operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is an electrical block diagram of the present utility model,
The specific embodiment
Comprise crash helmet 1 among the figure, head lamp 2, power supply 3, it is characterized in that: head lamp 2 adopts light emitting diode 4 (LED) to be light source, replace the mine lamp bulb, to improve luminous efficiency and to reduce power consumption, realize the long-life of light source, low-power consumption, high brightness, improve the uniformity of illumination, with the adaptability of light wave colour temperature to human eye, 3 of head lamp 2 and power supplys are provided with control circuit 5, control circuit 5 can be a constant-current source circuit, it also can be constant voltage power supply circuit, control circuit 5 is realized switch, charging to battery, supply current, the control of the constant and luminous intensity of voltage is (when simplifying circuit, can not use constant or supply current constant of supply voltage), power supply 3 all is positioned at crash helmet 1 inside with control circuit 5, described power supply 3 is a rechargeable battery (lithium battery, Ni-MH battery or nickel-cadmium cell serial or parallel connection are formed), replaced the structure heaviness, volume is big, complicated, chargeable number of times is few, and to human body, equipment and environment have the soda acid battery of harm.
