Description

A kind of Tunnel Lamp

Technical field

The utility model relates to a kind of LED light fixture, is specifically related to a kind of Tunnel Lamp.

Background technology

Tunnel is as the special road section of high-grade highway, when vehicle sailing into, by with roll away from the process in tunnel, " black-hole effect " or " white hole effect " that the sudden change of brightness produces vision, there will be a series of visual problem.For adapting to the variation of vision, Tunnel Lamp need be set.Tunnel Lamp, except being used in tunnel, is also applicable to the places such as workshop, bulk storage plant, venue, metallurgy and all kinds of plant area, engineering construction.The equipped light source of Tunnel Lamp of prior art is take incandescent lamp, high-pressure sodium, high-pressure sodium lamp, metal halide lamp as main, in light source, contain a large amount of mercury vapors, if broken mercury vapour, can evaporate in atmosphere, also containing mercury, lead, arsenic etc. has the element of severe contamination to environment, also brought harm to the mankind's health; And photoelectric transformation efficiency is low, thus a large amount of heat energy can be produced, on the contrary the light producing is just seldom; Add, the light exit direction of light source is uncontrollable, lighting angle is 360 degree, major part is only by mirror-reflection aluminium, and by light reflection out, light losing is serious, so though vertical illumination can reach outdoor lighting standard, but edge illumination is well below vertical illumination, and the uniformity is poor, can shine into light and dark phenomenon; In addition, if inside is installation high-voltage sodium vapor lamp words, in 1 year light decay up to 60%, colour rendering aspect, high-pressure mercury lamp is luminous be yellow, colour rendering index is only 20 left and right.

Comprehensive the above, the Tunnel Lamp of prior art has following shortcoming: 1. not environmental protection, has pollution; 2. efficiency is low, high energy consumption; 3. Luminescence Uniformity is low; 4. light decay is large, and colour rendering is poor.As can be seen here, the Tunnel Lamp of prior art still has many defects, and is urgently improved.

Utility model content

The purpose of this utility model is to provide a kind of environmental protection, there is no the Tunnel Lamp of pollution, to solve the problem of prior art.

For achieving the above object, the utility model provides a kind of Tunnel Lamp, comprise luminescence component, radiator, housing and upper cover, described luminescence component is connected with described radiator, described radiator is connected with described housing, described upper cover is connected with described housing, and described luminescence component comprises an aluminium base and be assemblied in several LED lamps on aluminium base, and described luminescence component also comprises:

Several lens, described several lens are connected with described aluminium base, and described several lens package overlay on described several LED lamps;

One sealing gasket, described sealing gasket is a lamellar body, on described sealing gasket, the position of corresponding described several lens, offers several through holes; In addition,

Described radiator and described housing are high heat conduction die casting aluminium.

According to the Tunnel Lamp described in the utility model preferred embodiment, also comprise a face shield, described face shield is the dull and stereotyped face shield of an indent aluminum, and on described face shield, corresponding described several LED lamps, offer several through holes, and described face shield is connected with described housing.

According to the Tunnel Lamp described in the utility model preferred embodiment, described upper cover is clear glass.

According to the Tunnel Lamp described in the utility model preferred embodiment, also comprise a sealing ring, the both sides of described sealing ring connect respectively described upper cover and described housing.

Based on above-mentioned, compared with prior art, the utlity model has following advantage.

1, the utility model has added optical lens, and the radiation direction that LED sends changes according to our specified direction, and light type well effectively utilizes light, luminous even, eliminates light and dark phenomenon in the whole region of illuminating; Light is soft, protection eyes, and without ultraviolet ray, mosquito proof, colour rendering is good, and more than colour rendering index Ra=85, light source utilization rate, up to 90%, consumes energy little.

2, the utility model environmental protection, does not pollute, and there is no the harmful substances such as mercury, can not work the mischief to environment and health, and the life-span is long, and after 50000 hours, luminous flux sustainment rate is more than 70%.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of a kind of luminescence component of the utility model;

Fig. 2 is the utility model exploded perspective view.

The specific embodiment

Below in conjunction with accompanying drawing, illustrate the utility model.

Please refer to Fig. 1 and Fig. 2.

A kind of Tunnel Lamp provided by the utility model, comprise luminescence component 10, radiator 20, housing 30 and upper cover 50, described luminescence component 10 is connected with described radiator 20, described radiator 20 is connected with described housing 30, described upper cover 50 is connected with described housing 30, described luminescence component 10 comprises an aluminium base 11 and is assemblied in several LED lamps 12 on aluminium base 11, described luminescence component 10 also comprises: several lens 13 and sealing gasket 14, described several lens 13 are connected with described aluminium base 11, described several lens 13 are coated on described several LED lamps 12, as shown in Figure 1, in the present embodiment, every row's LED lamp 12 and the quantity of lens 13 are 10, as shown in Figure 2, in the present embodiment, there are 10 row LED lamp 12 and lens 13, but can not be used for limiting this patent, the shape of each lens 13 is that the light type of launching is good, can effectively utilize all light emitting through the optical lens of design, luminous even, without optical flare, environmental protection, do not pollute, there is no the harmful substances such as mercury, can not work the mischief to environment and health, and in the situation for the type demand of not sharing the same light, replaceable lens 13 coordinates, in this application, when lens 13 bottom surfaces coordinate with aluminium base 0mm, it is best that the effect that light sends reaches, and beam angle is between 120 degree, and in this angular range, illuminated area is all uniform.The application uses lens 13 to design light is all put in appointed area, can eliminate light and dark phenomenon.
