Description

The light source projects structure of miner's lamp prepared from LED

Technical field

The utility model is about a kind of single High Power LED mine lamp, refers to the light source projects structure of miner's lamp prepared from LED especially

Background technology

Mine lamp is matchmaker miner people one of instrument very easily when excavating in the pit, because its bulb life of traditional light source is short, be easy to generate spark during fault, add the lead-acid battery that is used, the fire of blasting easily, therefore in recent years promptly the someone adopt low-power cold light a plurality of light emitting diodes as light source, but this type of lamp brightness deficiency, focusing effect are not good, so the someone tries to adopt the mine lamp of the light emitting diode of high power, high brightness as light source again.

See also Figure 1A, Figure 1A is the schematic diagram that adopts at present the mine lamp of high brightness LED, and Figure 1B is the schematic diagram of the rising angle of mine lamp for this reason then.Shown in Figure 1A, this mine lamp 1 mainly is made up of cooling stand 12, LED lamp source 14, reflecting surface body 16, lenticular body 18.This wherein the lamp socket 16A of reflecting surface body 16 be used for fixing cooling stand 12, LED lamp source 14 etc., lens mount 16B is used for fixing lenticular body 18.When LED lamp source 14 was lighted, the beam portion branch that it produced directly saw through lenticular body 18 and penetrates, and part is then still penetrated by lenticular body 18 after the reflection of reflecting surface body 16.

Shown in Figure 1B, this type of mine lamp can make the light beam that projects assemble as far as possible and be incident upon on certain ad-hoc location, and convection light can make light source can project farther place, and reflecting surface body 16 is designed to large-size for increasing its spotlight effect under this factor.This is because the LED lamp source 14 of this type of mine lamp 1 is not a spot light, therefore can't easily light beam be converged clip angle light beam.Promptly this mine lamp structure can't be dwindled thus and satisfy short and small frivolous designer trends.

The utility model content

Main purpose of the present utility model is providing a kind of light source projects structure of miner's lamp prepared from LED, the main platelet-like reflective face body that adopts, rely on the different angles between each sub-reflector, convection light makes light source can project farther position, but must volume and focusing distance can dwindle, also it directly can be arranged on the miners' cap, it is more convenient to allow use go up.

Based on above-mentioned purpose, the utility model is a kind of light source projects structure of miner's lamp prepared from LED, and this mine lamp comprises LED source, platelet-like reflective face body and lenticular body.This LED source is the light emitting diode of a high power, high brightness, is arranged at the inner edge bottom of platelet-like reflective face body.This lenticular body is that the light beam that will penetrate is assembled.The reflecting part that this platelet-like reflective face body is made up of a plurality of slice, thin piece reflectors constitutes, and this lenticular body is arranged at reflecting part outermost locations place, all connect between the sub-reflector of each of this reflecting part and roughly be and extend out shape, and the material on the inwall of each sub-reflector has the effect of folded light beam with certain degree.

Can be further understood by following novel detailed description and accompanying drawing about advantage of the present utility model and spirit.

The specific embodiment

See also Fig. 2 A～2B, be respectively the schematic diagram of structural representation of the present utility model and rising angle.Shown in Fig. 2 A, the light source projects structure of mine lamp 2 of the present utility model includes LED source 24, lenticular body 28, platelet-like reflective face body 30 etc., this LED source 24 is to be arranged at a cooling stand 22 places, both are the inner edge bottoms that are arranged at platelet-like reflective face body 30 in the lump, and this lenticular body 28 then is fixed in place, platelet-like reflective face body 30 other ends.It is to be provided with a sheet reflecting surface body 30 that the utility model is mainly improved part, these platelet-like reflective face body 30 main bodys are reflecting part, be by as sub-reflector 30A, a plurality of slice, thin piece reflectors such as 30B, 30C constituted, this platelet-like reflective face body 30 is to adopt structure on two sides for symmetrical in the present embodiment.Because the effect that the material on the sub-reflector 30A of platelet-like reflective face body 30, the inwall of 30B, 30C has folded light beam, add that

sub-reflector

30A, 30B, 30C connection angle each other is the angle of confirming through prior design, so light beam that mine lamp 2 of the present utility model is throwed away, except light beam is projected on certain specified point (shown in Fig. 2 B) by gathering, can also design various light beams projection shapes.

As shown in Figure 3, mine lamp structure for the another kind of symmetric form of the utility model, as shown in the figure, these mine lamp 4 integral body are flat, and this platelet-like reflective body 40 also is flat, the different angles of inner utilization through designing, the sub-reflector of shape cooperate 48 designs of different lenticular bodies to meet the required mechanism's external form of various mine lamps.Particularly, because the reflecting part in the utility model platelet-like reflective face body 30 (or 40) mainly is made up of

sub-reflector

30A, 30B, 30C, it is not the only single cambered surface of reflecting surface body 16 as known mine lamp 1, so the inner reflecting part in the utility model platelet-like reflective face body 30 (or 40) can utilize the angle of adjusting between

sub-reflector

30A, 30B, the 30C, makes that the volume or the focusing distance of the utility model mine lamp 2 integral body are little.In addition as need improve spotlight effect again the time, also can use the angle of adjusting between

sub-reflector

30A, 30B, the 30C, under the situation that need not increase platelet-like reflective face body 30 overall volume, still can improve spotlight effect.

In addition, be can be controlled also because of the angle between

sub-reflector

30A, 30B, the 30C, therefore if the utility model mine lamp 2 in outward appearance in shape or light beam projection shape need adjust the time, also can suitably adjust the angle that changes between

sub-reflector

30A, 30B, the 30C, its spotlight effect that provides is not changed because of the change of overall volume or change light source form.

Fig. 4 is the another kind of illustration of implementing of the utility model, is mainly an asymmetrical structure.As shown in Figure 4, the utility model still has cooling stand 52, LED source 54, lenticular body 58 etc.But in the present embodiment, the reflecting part of this platelet-like reflective face body 50 is to form with asymmetric manner at structure on two sides, is different inclined-plane and angles as

sub-reflector

50A, 50B, 50C with the sub-reflector 50D of opposite side, 50E, 50F, and the reflecting part of being formed with these asymmetrical a plurality of slice, thin piece reflectors also can make light source projects in default position.

By the above detailed description of preferred embodiments, be to wish to know more to describe feature of the present utility model and spirit, and be not that the above preferred embodiment that discloses comes category of the present utility model is limited.On the contrary, purpose is to wish to contain various changes and have in the category of the claim that is arranged in the desire application of the utility model institute of equality.
