Description

The composition type miner's lamp prepared from LED lamp holder

Technical field

The utility model relates to a kind of composition type miner's lamp prepared from LED lamp holder, is a kind of have optical texture and LED light emitting diode combined holder of miner's lampe together, belongs to the miner and uses ligthing paraphernalia.

Background technology

The LED miner's lamp prepared from LED has obvious superiority with respect to old-fashioned tungsten filament bulb mine lamp, and current LED mine lamp is used widely.But present LED holder of miner's lampe still comes with some shortcomings, and mainly contains:

1.LED two kinds of LED light emitting diodes of the general use of holder of miner's lampe, a kind of is the above great power LED of 1W, and its electro-optical efficiency is lower than common LED.Another kind is to arrange a plurality of common LEDs simply, and its light of launching does not effectively make full use of.More than two kinds all require battery capacity 4-6Ah at least, just can reach the requirement of standard illumination and time.Thereby cost is higher, volume is big, weight is heavier.

2. owing to need the battery of larger capacity, mine lamp weight is heavier, is not easy to integrated head lamp formula mine lamp design, otherwise the front end that is contained in miners' cap can make the cap imbalance.

3, light color is blue and not soft partially, even good not as good as the light color of old-fashioned mine lamp.

4, the hot spot uneven illumination is even, and the ring of light is arranged, and influences the effect of object observing.

The utility model content

At above-mentioned technical problem, the utility model improved a kind of energy-conservation, optical effect good, combined LED miner's lamp prepared from LED lamp holder in light weight and easy to use;

Finishing the technical measures that above-mentioned task takes is:

The utility model is the combination of one group of LED and optical texture: comprise the LED light emitting diode group as light source, center and be uniformly distributed along the circumference 4～10 compound eye condensers are set in the cambered surface of garden around the center, 4～10 led light sources are separately positioned on the object distance place that is respectively 0-5mm apart from compound eye condenser and compound eye center condenser, make the virtual image that LED optically focused becomes on the focus of main condenser or on every side, then this virtual image forms directional light through main condenser, in housing, the compound eye condenser is embedded in the corresponding hole of lens carrier, main condenser is placed on the step of housing, be threaded between lamp holder lid and the housing, and main condenser pushed down, led light source is inserted in the corresponding hole, lens carrier bottom, and the pin of led light source is welded on the circuit board, with the parallel connection of led light source both positive and negative polarity, and on circuit board, form positive limit and negative pole point, be connected with power line respectively again, power supply adopts lithium battery, circuit board is fixed on the bottom of lens carrier, and lens carrier is fixed on the ring-shaped step of housing with screw.

Advantage of the present utility model:

1. under the nominal operation situation, the common LED electro-optical efficiency is 3 times of 1W great power LED, and this is because of great power LED integrated level height, and heat dissipation problem does not have good way and solves.Owing to adopt the high common LED of electro-optical efficiency, and carry out accurate optical design, made full use of electric energy and luminous energy, thereby the reduction of required battery capacity, thereby cost also reduces, and the mine lamp volume can reduce, and weight can alleviate.

2. owing to the battery that can use than low capacity, cause volume less, weight is lighter, is convenient to carry out integrated head lamp formula mine lamp design.

3.4-10 common LED light source only, the light that it sent by compound eye condenser and main condenser after, formed directional light, no matter thereby the distance of distance, can both realize illuminance evenly, the no ring of light is convenient to object observing.
