Abstract

Disclosed is a compound-lens lamp of miner, comprising a lamp holder 1, a lamp ring 2, a sealing ring 3, a heat-dissipating aluminum base plate 7 and a PCB board 8, which is characterized in that the lamp also comprises an integrated optical lens 4 which is assembled by a first lens 401, a second lens 403, and a reflecting system lens 402, all of which are connected as a whole, a high-power LED tube 5, and a high-luminance LED tube 6. Compared with the cold light source lamps of miner of the prior art, the compound-lens lamp of miner is provided with a light source that can create on the observation surface an evenly distributed illumination effect similar to diffused light, which greatly enhances the distinguishing ability of human eyes. When retaining the size and weight of traditional lamps of miner, the utility model increases the effective area of the lamp of miner illumination spot, makes the illumination spot even and gentle, and provides higher luminescent efficiency. The utility model overcomes the drawbacks of excessively strong illumination spots on partial areas, eye-offending light, small illumination spots, and illumination intensity jump in the traditional lamp of miner. And at the same time, the utility model also effectively increases the illumination intensity of short-distance beams, which is more suitable for the physiological characteristics of human eyes and promotes the observation surface color matching accuracy and chromatic aberration discrimination ability of human eyes. The utility model is a quite ideal illuminating device for miners to carry out down-hole operations.

Description

The compound lens mine lamp

One, technical field

The utility model belongs to the what lighting apparatus, particularly a kind of cold light source mine lamp.

Two, background technology

Mine lamp is the mobile lighting apparatus in zonule that the miner carries when underground work.Usually consider for safety, light and suitable factor such as move, adopt the powered battery of finite capacity, and require its optical design efficient as far as possible.At present, the market is to adopt cold light source and the combined product of meniscus mostly, and its lens are all thicker big, mainly emphasize the optically focused effect, and the luminous energy attenuation is relatively large; This mine lamp is in order to reach stronger optically focused purpose, the effective hot spot that forms is less than normal, local light according to the center strong and edge a little less than, certainly will cause the less and illumination sudden change of user available field of view more obvious, make human eye to the precision of sightingpiston color-match with distinguish that the ability of aberration is not high, illuminating effect is undesirable.In addition, also have a kind of cold light source and combined product of minute surface reflection subassembly of adopting, the reflecting curved surface of this mine lamp and reflection assembly existing problems, can not accurately control the ideal distribution of illumination in available field of view, the existing above-mentioned defective of a kind of mine lamp product before equally also can't overcoming, it can not fully satisfy the precision of eye-observation color-match and distinguish that the aberration ability wants high requirement, can not satisfy the physiological requirements of the long-time comfortable work of human eye.

Three, summary of the invention

Above-mentioned defective at the existence of prior art mine lamp, propose meter and make a kind of compound lens mine lamp, keeping under traditional mine lamp volume weight condition, the available field of view that makes it illumination increases, Illumination Distribution is even, improve the precision and the ability of distinguishing aberration of eye-observation color-match, make the illuminating effect of miner when underground work comfortable.

Technical solution adopted in the utility model is as follows.

A kind of compound lens mine lamp includes lamp socket, lamp ring, sealing ring, heat-radiating aluminum plate and pcb board (printed circuit board (PCB)), it is characterized in that:

1) it also has the combination of sets accepted way of doing sth optical lens that is connected as a single entity by first lens, second lens and reflecting system lens, great power LED pipe and high-brightness LED pipe;

2) be provided with anchor post 2 symmetries and that be connected as a single entity with lamp socket in the lamp socket, the heat-radiating aluminum plate is arranged in parallel with pcb board and is connected with anchor post with screw, the great power LED pipe is fixed on the center of heat-radiating aluminum plate, at least 2 high-brightness LED pipes pass the heat-radiating aluminum plate and are fixed on the pcb board, the sealing ring coupling is on the end face of lamp socket port, on sealing ring, shelve combination of sets accepted way of doing sth optical lens, the termination of great power LED pipe is stretched in the centre hole of combination of sets accepted way of doing sth optical lens, lamp ring links to each other with the lamp socket screw thread, makes combination of sets accepted way of doing sth optical lens and lamp socket fit sealing.

In above-mentioned compound lens mine lamp, said first lens are in the centre of combination of sets accepted way of doing sth optical lens, a kind of in biconvex mirror, planoconvex lens or the concave and convex lenses; Said second lens are in the periphery of combination of sets accepted way of doing sth optical lens, a kind of in biconvex mirror, planoconvex lens or the concave and convex lenses; The position of said reflecting system lens between first lens and second lens, by reflection conical surface angle in 45～75 degree scopes speculum and the refracting telescope that is connected as a single entity with it form.

The compound lens mine lamp of the utility model structure, the light of active and standby light source (great power LED pipe and high-brightness LED pipe) emission can be spent left and right sides science distribute light flux at optimal viewing angle 10, refraction by combination of sets accepted way of doing sth optical lens, reflection and complex optical path such as focusing more finally provide the available field of view of sening as an envoy to heighten and the uniform illumination light of Illumination Distribution.It is compared with the cold light source mine lamp of prior art, and light source can produce the illumination of uniform similar diffused light effect on sightingpiston, greatly improved the human eye resolving ability; Keeping under traditional mine lamp volume weight condition, it has increased mine lamp irradiation hot spot effective area, makes hot spot evenly soft and light efficiency is higher, overcome the irradiation hot spot of traditional mine lamp local strong excessively, dazzling, hot spot is little and drawback such as illumination sudden change; Simultaneously, it has also increased the dipped beam illuminance effectively, makes it to meet more the human eye physilogical characteristics, improves the precision and the ability of distinguishing aberration of human eye to the sightingpiston color-match.
