Abstract
The utility model provides an LED cold light source miner's lamp, which comprises a casing, a transparent lamp cover arranged at the front end of the casing, a basal plate arranged on the casing at the back side of the transparent lamp cover and a plurality of light emitting diodes fixed on the basal plate. The axial leads of the light emitting diodes are cross at the front part of the casing. The light emitted from each LED light emitting diode is the parallel light, and thus the axial leads of the light emitting diodes are cross to form a focal point An at the front part of the utility model to fulfill a condensing function.
Description
Technical field
The utility model relates to a kind of mine lamp that is used for usefulness such as all kinds of mines, underground work.
Background technology
In the prior art, the mining bulb of 4V direct current, 0.6～0.7A, parabolic mirror combining structure that present domestic mine lamp adopts mostly.The matching used power volume of institute is big, and weight is also bigger, carries inconvenience; The power consumption of bulb is big, and temperature can reach several Baidu when bulb used, and can't reach the safety requirements in the ore deposit, and service life is short.In order to overcome this weak point, people have adopted a kind of new LED cold light source mine lamp, and it is big to have solved mining bulb power consumption, and matching used power volume reaches problems such as easily causing coal mine gas from explosion greatly.The preceding transparent lamp shade of this product has adopted a plurality of convex lens to carry out the focusing of light, and the corresponding LED cold light source of each convex lens, and therefore the production process of this lens is too much, cost up.
Summary of the invention
The purpose of this utility model provides a kind of LED cold light source mine lamp simple in structure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of LED cold light source mine lamp, comprise housing, be arranged at the housing front portion transparent lamp shade, be arranged at substrate on the housing of rear side of transparent lamp shade, be fixed in a plurality of light emitting diodes on the described substrate; The axial line of described each light emitting diode intersects at the front portion of housing.
Because technique scheme utilization, the utility model compared with prior art has following advantage: because the light that each LED light emitting diode itself sends is mainly parallel rays, therefore the axial line of light emitting diode intersects and can form a focus A in the place ahead of the present utility model, can play the effect of optically focused.
Description of drawings
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is the cutaway view of front portion of the present utility model;
Wherein: wherein: 1, housing; 2, transparent lamp shade; 3, light emitting diode; 4, substrate;
The specific embodiment
Referring to accompanying drawing 1 to shown in the accompanying drawing 2, a kind of LED cold light source mine lamp, comprise housing 1, be arranged at housing 1 front portion transparent lamp shade 2, be arranged at substrate 4 on the housing 1 of rear side of transparent lamp shade 2, be fixed in a plurality of light emitting diodes 3 on the described substrate 4; The axial line of described each light emitting diode 3 intersects at the A place of the front portion of housing 1.The front surface of described substrate 4 is the spill that caves in backward, makes each light emitting diode 3 to install by state as shown in Figure 2.
Described transparent lamp shade 2 is convex lens.The front surface of described substrate 4 is parabolic, and front surface that also can described substrate 4 is a sphere.
