Description

The lighting device that is used for freezing environment

Technical field

The utility model relates to a kind of lighting device, particularly a kind of lighting device that is used for freezing environment, and referring to especially a kind ofly can need fast opening and closing according to the user in freezing environment, illumination is provided, and is not subjected to freezing ambient influnence, keeps the lighting device of lighting quality.

Background technology

As everyone knows, only a kind of energy, mode straightline propagation with fluctuation, Edison not before the invention bulb, obtaining of light is very difficult, removes sunlight, moonlight, outside the natural daylights such as starlight, needing to throw light on just only can be by burning fire light, artificial light sources makes the mankind can freely select lighting source, directly utilize natural daylight, perhaps open light bleached daytime night, still, along with development of science and technology, the lifting of living standard, light source not only are used in indoor and outdoor lighting, also are used in various extreme temperature, the environment of humidity, the following freezing environment of zero centigrade for example, the scope of utilization is very extensive;

Freezing environment as the refrigerator reach in freezer, or even large-scale refrigerating chamber space owing to can store fresh meats such as fish, meat, is used for keeping for a long time the freshness of food materials, or is used for operation experiments, be modern industry with life in indispensable storage instrument;

Because temperature is extremely low in the freezing environment, generally be lower than below the zero centigrade more, do not set suitable light source if having, user Chang Wufa is in not only black but also cold environment, be engaged in and choose, store kinds of goods or relevant low temperature test work, yet general lighting source, utilize the luminous traditional tube of mercury vapour media or utilize the high thermoluminescent bulb of tungsten filament no matter be, in freezing environment, all be difficult for the unlatching temperature that reaches enough, phenomenon such as in use easily produce the light decay clarinet and glimpse, service life is short;

On the market at the particularity of freezing environment, design has a kind of antifreeze fluorescent tube, can provide illumination for a long time in freezing environment, but above-mentioned structure is in use at present, implicit many manufacturings and the shortcoming of using:

1, this antifreeze fluorescent tube in use must collocation transformer and brake, can start smoothly at this low temperature environment, and this transformer and brake is in the environment of long-term low temperature and moisture, and the short circuit of seeping water easily influences service life of antifreeze fluorescent tube simultaneously;

2, this antifreeze fluorescent tube is when illumination, must current flow heats reach suitable operating temperature, illumination can be provided, under the freezing environment, antifreeze fluorescent tube is in the process of heating, make tube glass because of the embrittlement of expanding with heat and contract with cold easily, cause tube glass to break, jeopardize the user, therefore general antifreeze fluorescent tube must often be protected opening in use, make the tube glass surface can keep an equilibrium temperature, avoid the embrittlement of expanding with heat and contract with cold, but this kind lighting system, when the user leaves reefer space, still need make antifreeze fluorescent tube be held open the state of illumination, not only power consumption, the service life of the antifreeze fluorescent tube of more relative shortening;

3, antifreeze fluorescent tube is compared to traditional tube, bulb, and its cost of manufacture is high, and follow-up replacement cost is also high;

Recently lighting apparatus is except traditional fluorescent tube and bulb, it is light and handy that light-emittingdiode has a volume, can save multiple advantages such as a large amount of energy, but its luminosity can't reach the level of conventional lamp always, thereby light-emittingdiode can't be applied on the actual illumination, its reason is relevant with the luminous efficiency of light-emittingdiode own; always For improving the problem of traditional light-emittingdiode luminance shortage, exploitation has a kind of high-power light emitting diode on the market at present, is to utilize the increase electric current to improve its luminous efficiency, reaches high brightness, thereby can be used on the actual illumination; But, because the high-power light emitting diode is by increasing electrical power, increase electric current to improve its luminous efficiency, incident problem is to increase with electric current, the electrical power that is consumed increases, and the problem that the generation amount of localized heat excessively raises, yet the suitable operating temperature of high-power light emitting diode is spent between 30 degree Celsius about Celsius 45, overheated operating temperature can cause the wafer physical characteristic in the light-emittingdiode to change, make light-emittingdiode therefore can't reach predetermined brightness, the worry of damage is more arranged, need be improved.

The utility model content

According to the purpose of this utility model, shortcoming at existing lighting device existence, a kind of lighting device that is used for freezing environment is provided, and it mainly is at least one LED lamp group to be set form in a reefer space, provides illumination by LED lamp group is luminous to reefer space; This reefer space is a reach in freezer, this reach in freezer has a cabinet body, in the cabinet body, be provided with at least one accommodating chamber, be provided with a door pillar in this accommodating chamber front end, and be respectively equipped with a cabinet door in these accommodating chamber front end both sides, be mounted on appropriate location in the reach in freezer in order to seal this accommodating chamber LED lamp, be located at a side or the interior rear end of reach in freezer in the reach in freezer; Be provided with a sensing unit in the reach in freezer and connect this LED lamp group, whether be unlocked, decide to drive this LED lamp group in order to induction cabinet door; This LED lamp group has a transparent cover, is provided with a substrate in this transparent cover, is laid with plural LED lamp body on this substrate, and this transparent cover two ends envelope is provided with a cover plate, and transparent cover is provided with the staggered line of plural number.

Advantage of the present utility model is: can need fast opening and closing according to the user in freezing environment, illumination is provided, and have long-acting service life; And LED lamp group need not arrange in pairs or groups transformer and brake utilize the characteristic of the low operating temperature of LED lamp group, smoothly the normal LED lamp group that starts in freezing environment; LED lamp group, in the start-up course of heating, can not broken because of the embrittlement of expanding with heat and contract with cold under freezing environment because operating temperature is low, and safe LED lamp group is long service life not only, and its cost is also low than the antifreeze fluorescent tube of tradition, and the frequency that follow-up maintenance is changed is also lower.
