The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment 1:

The utility model miner's lamp prepared from LED is made the luminous illuminating device of mine lamp with high brightness LED, mainly is made of lamp holder, battery, mine lamp cable.Because lumination of light emitting diode efficient is much larger than incandescent lamp, the power consumptive province significantly reduces the volume and weight of battery, and can make lamp holder and battery designs is wear-type.For easy to use flexible, adopt inserting mode between lamp holder, battery, the safety cap.

Agent structure at the lamp holder of present embodiment miner's lamp prepared from LED shown in Fig. 1,2.It is mainly by shell (2), lid (4), lens (6), high brightness LED (5) and be configured to.For guaranteeing the requirement of illumination, each lamp shell (2) domestic demand is installed many light emitting diodes (5) and is constituted.Wherein a light emitting diode (5) be central tube, the position after leaning on, the center that is positioned at lamp holder, fixing by central tube support (1); Remaining many light emitting diode (5) is fixed on the peripheral tubes support (3) of annular groove-shaped along periphery one circle.Central tube support (1) and peripheral tubes support (3) are except playing fixation, and its inner surface is mirror surface, a light reflex.The light that central tube and peripheral tubes are sent, respectively the center of scioptics (6) and two different parts of periphery penetrate, by lens (6) with two parts light focusing.Therefore require lens with peripheral position different curvature and structure to be arranged in the centre: the centre is convex lens, focuses on for the light beam of central tube; The vertical section at periphery position is a wedge shape, and the light beam of peripheral tubes is reflected to the center.This structure can be implemented under the situation that does not reduce luminous flux, makes the light intensity in centre obtain higher lifting.

High brightness LED (5) in the holder of miner's lampe generally adopts 9～21 compositions; Be illustrated as 13, be at least 7.During with 9, luminous flux and illuminance foot have reached setting.Can increase to 21 according to on-the-spot instructions for use, to improve luminous flux and illuminance.

Overall formation and two kinds of assembling modes thereof at present embodiment miner's lamp prepared from LED shown in Fig. 3,4.It mainly is made of the electric wire (14) in above-mentioned lamp holder (7), battery (12), the safety cap.Lamp holder (7), battery (12), safety cap adopt inserting mode between (10).Lamp holder (7) has two kinds with the assembling pattern of battery (12).A kind of is by common mode lamp holder (7) and battery (12) to be inserted the forward and backward two ends that are associated in safety cap (10) respectively, so that work.Another kind is with lamp holder (7) and battery (12) is directly slotting is associated in together, does hand-held the use.

Fig. 8 illustrates present embodiment and is plugged on assembling mode on the safety cap.Lamp shell (2) and latch (8) thereof are hinged by bearing pin, and latch (8) can be gone up vertical Rotate 180 ° at shell (2).The shell of battery (12) is provided with a socket (11).The front and back ends of safety cap (10) is being fixed a socket (9) and a latch (13) respectively.Safety cap (10) front end socket (9) and rear end latch (13) connect by the electric wire (14) in the safety cap (13), and electric wire (14) is as the mine lamp cable.

Lamp holder (7) is plugged on the socket (9) of safety cap (10) front end by the latch (8) of its shell (2).Battery (12) is plugged on the latch (13) of safety cap (10) rear end by its socket (11).Battery (12) is by light emitting diode (5) power supply in lamp holder of the electric wire (14) in its socket (11), latch (13), the safety cap, socket (9), lamp holder latch (8).Each latch, socket have machinery and electric anastomosis simultaneously.

The mine lamp of this assembling mode need be designed to essential safety-type, and battery must adopt the intrinsic safety type power supply storage battery.For example: the lithium battery that can select the 1CR18650W1 type of equipped overcurrent protection for use.

Fig. 4 illustrates the assembling mode of present embodiment when hand-held.When hand-held the use, lamp holder (7) and battery (12) are taken off from safety cap (10), lamp holder (7) is directly inserted with socket (11) by its latch (8) with battery (12) be associated in.Directly power to lamp holder by intrinsic safety type battery (12) through socket (11), latch (8).

Embodiment 2:

Lamp holder (7) adopts the mine lamp cable directly to connect power supply with the connecting mode of battery (12).The socket of the latch on the lamp holder (7), battery (12), and the socket and the latch of safety cap (10) front and back ends, only play the mechanical attachment effect this moment, and do not have electric connection.This pattern can needn't adopt the intrinsic safety type power supply storage battery by the explosion-proof criteria design of general mine lamp.All the other are identical with embodiment 1.

Processing and manufacturing:

The specification of high brightness LED: diameter phi 5mm, more than the brightness 8000mcd, operating current 20～30mA is about voltage CD 3.5V.The luminous tube that meets above parameter all can use, as: SG50W34A etc.

Because the present particular product performance parameters of light emitting diode mainly is light quantity and electric current, less stable when making mine lamp, needs the screening grouping.All the other parts adopt standard component as far as possible.
