Abstract
The utility model relates to an LED mining lamp which comprises a lamp body, a circuit board, a drive power source, nine bullet-like condensing LED lamps, and a trapezoidal reflector. The circuit board is located in the lamp body. The drive circuit and the nine bullet-like condensing LED lamps are disposed on the circuit board. The trapezoidal reflector is fitted behind the LED lamp. A protective circuit board is disposed in a lithium-ion battery. When input voltage of the lithium-ion battery ranges from DC 2.7V to DC 4.2V, output voltage is kept at constant-DC 3.7V. The lithium-ion battery powers the LED lamp disposed on the circuit board. The LED mining lamp has the advantages of effectiveness in light condensing, high luminous intensity, energy saving, long service life, less easiness in damage of a solid light source, small size, light weight, long service life, convenience in charging, safety, reliability and the like. A battery of the traditional split mining lamp is integrated into the lamp body, and accordingly the LED mining lamp is simpler and more convenient to use.
Description
Technical field
The utility model relates to a kind of mine lamp, especially a kind of LED mine lamp.
Background technology
Mine lamp is mainly used in the place that mine, tunnel etc. need illumination, the employed luminous component of mine lamp in the past, most of incandescent lamp bulb or based on halogen bulb of adopting; Have only 15% electric energy to be converted into luminous energy; Both consumed energy, and the lamp pearl life-span is short, in recent years; The LED lamp is widely applied on the mine lamp because of advantages such as its long-life energy-savings.
The utility model provides a kind of LED mine lamp, comprises shell, lamp body and lithium battery, and the front of shell is a transparent explosion-proof lamp surface glass; 3 grades of key switches are equipped with in the lower end, and charging primary socket and the hook that is inserted into the ore deposit cap are housed in the bonnet, are provided with circuit board in the lamp body; Circuit board is provided with the LED lamp of 9 bullet-shaped optically focused, and wherein the parallel connection of 8 LED lamps is one group, is the main light source of LED mine lamp; Other one is the secondary light source of LED mine lamp, is connected with key switch respectively.On circuit board, also be provided with driving power and current-limiting resistor voltage divider.Be provided with reflector at the back at the LED lamp, the light that the LED mine lamp is sent reflexes to the place ahead; Its luminous intensity greatly improves; The power supply of the lithium battery of a 2.5Ah as the LED mine lamp is housed in bonnet, also is provided with holding circuit on the lithium battery, can protect lithium battery to stop power supply when under-voltage being lower than DC2.7V; When charging, when lithium battery voltage is higher than DC4.25V, stop charging, the safety of protection lithium battery.
The utility model content
This practicality letter is novel to provide the LED that a kind of optically focused is good, luminous intensity is big mine lamp.
Realize the utility model LED mine lamp, comprise lamp body, be positioned at the circuit board of said lamp body; Be located at driving power and 9 bullet-shaped light-focusing type LED lamps on the circuit board; And behind the LED lamp, be equipped with trapezoidal reflector, the holding circuit plate is housed, when the input voltage of lithium battery during in the lithium battery at DC2.7V-4.2V; Output voltage remains on the DC3.7V constant current, and the LED lamp that is contained in said circuit board is given in power supply.
The beneficial effect of the LED mine lamp of the utility model is following:
The LED mine lamp of the utility model adopts the LED lamp of bullet-shaped also to join reflector, advantage such as have that spotlight effect is good, luminous intensity is high, durable energy saving, solid light source are not fragile.This LED mine lamp adopts lithium battery, and baffle is housed on the lithium battery, has advantages such as volume is little, in light weight, the life-span long, charging is convenient, safe and reliable, and the battery of traditional split type mine lamp is attached together in lamp body, uses more simple and convenient.In the LED mine lamp, drive circuit is installed, when the input voltage DC2.75V-4.2V of lithium battery changed, drive circuit can be stabilized in 3.7V constant current output with power supply, makes LED mine lamp working stability.
The utility model also adopts the work of major-minor lamp two-way, and the king light working time surpasses 11 hours, and auxilliary lamp work surpasses 80 hours, can satisfy use needs different in the mine.
Description of drawings
Fig. 1 is the structural representation of the utility model LED mine lamp.
The specific embodiment
The embodiment of the utility model is following:
As shown in Figure 1, the utility model LED mine lamp comprises lamp body; Said lamp body is made up of the explosion-proof lamp surface glass 2 of shell 1 and shell front end, on the key switch rubber compressing tablet 3 of shell lower end, the shell bonnet charging socket 4, hook and lithium battery 10 is arranged, and is positioned at the circuit board 6 of said lamp body; Be located at driving power and 9 bullet-shaped light-focusing type LED lamps 7 on the circuit board 6, and behind the LED lamp, be equipped with trapezoidal reflector 8, said circuit board is provided with key switch 9; Be located at holding circuit plate 11 is housed in the lithium battery 10; When the input voltage of lithium battery during at DC2.7V-4.2V, output voltage remains on the DC3.7V constant current, and the LED lamp that is contained in said circuit board is given in power supply.
The utility model LED mine lamp when normal the use, is pressed the key switch of king light, and 9 LED work simultaneously, when only needing auxilliary lamp bright, can press key switch again, and at this moment a LED works, but continuous operation 80 hours.The utility model LED power saving easy to use, efficient, long-life safety.
