Abstract
The utility model relates to an LED lithium cell mine lamp which comprises a casing, and a lithium cell, a control circuit board, an LED light source and a light reflecting bowl which are arranged in the casing. The utility model is characterized in that the light reflecting bowl is a light-gathering light reflecting bowl, the LED light source is installed in a blind hole on the back face of the light reflecting bowl, and the back face of the light reflecting bowl is coated with a light reflecting layer. After the light-gathering light reflecting bowl is adopted, the utility model has the advantages of thickness reduction and volume reduction, light rays emitted by the LED light source is refracted by a lens, are reflected by the light reflecting layer and then are highly gathered into a beam shape, therefore the irradiating distance of the utility model is greatly enhanced so that the illuminating effect is obviously reinforced.
Description
Technical field:
The utility model relates to a kind of light fixture, is applicable under the mine, in explosive gas atmosphere and the New LED lithium battery mine lamp that easily is hit, uses under the mal-condition such as vibration.
Background technology:
The mine lamp that China's coal-mine and other industries are used for a long time is the power supply of acid, alkaline cell, the incandescent lamp bulb old-fashioned light fixture as light source.At present, be that the novel miner's lamp of light source emerges with the LED light emitting diode, this mine lamp is in light weight, and energy consumption is low, and dependable performance is easy to maintenance, long service life.This mine lamp generally constitutes by casing and the parts such as lithium battery, control circuit board, led light source, reflector and potted component that are installed in the casing, lithium battery is powered to led light source by drive circuit and holding circuit, controls the break-make of main and auxiliary light source by switch; The reflector center is porose, light source puts in from the hole, and the front of bowl is coated with reflector layer, and the light that light source is sent reflects away, improve illuminating effect, be further to improve illuminating effect, the somebody is installed convex lens additional before reflector, though the structure that this reflector adds convex lens during only with reflector irradiation distance can improve, but irradiation distance and illuminating effect are still undesirable, light still can not highly be assembled, and the lamp holder of mine lamp is elongated thus, and volume is also bigger.
Summary of the invention:
The purpose of this utility model provides a kind of optically focused, illumination performance is good, the LED lithium battery mine lamp that volume is little.
Solution of the present utility model is, LED lithium battery mine lamp comprises casing and is installed in casing interior lithium battery, control circuit board, led light source, reflector, be characterised in that, there is blind hole at the back side that is installed in the light collecting reflector in the casing lamp holder, led light source is installed in the blind hole at the reflector back side, and the back side of reflector is coated with reflector layer.
Advantage of the present utility model and effect are, after adopting light collecting reflector, the thickness of mine lamp reduces, volume reduces, and pencil is assembled, is reflected into to the down-hole has reduced collision and pounded in using probability, the light height that light collecting reflector can send light source, irradiation distance increases substantially, illuminating effect obviously strengthens, and it is long-pending big to have solved prior art chats lamp body, the problem of the nearly weak effect of illumination distances.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Components and parts such as lithium battery, control circuit board omit and draw among the figure, led light source with and the wiring of its connection element omit and draw.
The specific embodiment:
The front end of casing 1 is circular lamp holder 6, and implosion guard 5 is encapsulated in the front end of lamp holder 6 by sealing gasket 2, and the back of implosion guard 5 is light collecting reflectors 4; There is blind hole at the center, the back side of reflector 4, and led light source 8 is arranged in the blind hole, and this light source adopts the main light source of large-power light-emitting diodes as mine lamp, and heat radiation pressing plate 9 will be fastened in the lamp holder 6 of casing 1 front end as the led light source 8 and the reflector 4 of main light source; Reflector 4 is thin, the middle thicker convex lens in an edge, the front concave-shaped of reflector 4 concave surface 3 in the arc-shaped, back side spirogyrate convex surface 10 in the arc-shaped; The small blind hole of secondary light source 7 is placed at the back side of reflector 4 in addition, and lower-powered light emitting diode is placed in the small blind hole, when main light source breaks down, by secondary light source 7 emergency lightings; The back side of reflector 4 is coated with reflector layer, and the light that main light source sends enters lens from blind hole, and through the refraction of lens and the reflection of reflector layer, light highly is gathered into pencil, and the irradiation distance of mine lamp increases substantially, and illuminating effect obviously strengthens.
