Abstract
The utility model relates to an LED (light-emitting diode) spot lamp. The LED spot lamp comprises a press cover, a heat dissipation device, a lamp cover and a lamp cap which are arranged in sequence; an LED lens, an LED light source and an aluminum substrate are arranged between the press cover and the radiator; a circuit board is arranged between the radiator and the lamp cover and provided with a power supply driver; the front surface of the radiator is provided with a turbine-shaped heat-dissipation groove, and the back surface thereof is provided with a cyclone-shaped heat-dissipation duct; a fan which is connected with the circuit board is arranged between the heat dissipation device and the circuit board in the lamp cover; and the heat generated in the LED spot lamp when the LED spot lamp works can be blown out of the body of the LED spot lamp from the heat-dissipation groove. The LED spot lamp provided by the utility model is reasonable in structural design. The air inlet and outlet ducts of the fan are independent air inlet and outlet ducts. When the LED spot lamp works, the fan begins to work immediately. The natural cold air sucked in through the heat-dissipation hole of the lamp cover is used for actively dissipating the heat of the heat dissipation device, and then the natural cold air is blown out of the body of the LED spot lamp through the cyclone-shaped heat-dissipation duct, thus the work temperature of the power supply driver can be decreased, the normal work of the driving device can be guaranteed effectively, and the service life of the LED spot lamp can be prolonged.
Description
Technical field
The utility model relates to LED lamp lighting technical field, specifically refers to a kind of LED shot-light.
Background technology
Along with the raising of people's living standard, the LED shot-light applies in the daily life more and more at large.
At present, because the restriction of light fixture volume, low-power LED reflectoscope is difficult to reach the needed brightness of people, if use high-power LED spotlight, then easily because the light fixture radiating effect is not good, cause the led light source operating temperature too high and shorten lamp life, increase use cost, consume energy also high, be unfavorable for popularization and the use of LED shot-light product.
Summary of the invention
Technical problem to be solved in the utility model provides the better LED shot-light of a kind of radiating effect.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
A kind of LED shot-light, comprise gland, radiator, lampshade and the lamp holder installed successively, between gland and radiator, be provided with LED lens, led light source and aluminium base, between radiator and lampshade, be provided with circuit board, power supply driver is installed on the circuit board, be provided with the turbine-like radiating groove in the radiator front, be provided with the heat dissipation wind channel of whirlwind shape at the radiator back side; Between lampshade inner radiator and circuit board, be provided with the fan that is connected with circuit board, the heat of lamp interior can be blown out lamp body from radiating groove during light fixture work.
Be provided with the temperature protection switch that is connected with circuit board on the above-mentioned aluminium base.
Above-mentioned gland is connected with the radiator clamping.
Above-mentioned lampshade is provided with louvre.
The utlity model has following remarkable result:
The utility model LED shot-light structure is reasonable in design, stable connection by the heat dissipation wind channel of turbine-like radiating groove and whirlwind shape is set at radiator, and arranges fan between lampshade inner radiator and power supply driver, fan is connected with circuit board, and the turnover air channel of fan is respectively independent ventiduct; After the light fixture work, fan is worked immediately, suck nature cold wind from the louvre of lampshade, radiator is carried out active heat removal, then blow out lamp body by cyclone channel, can reduce like this operating temperature of power supply driver, effectively guarantee the drive unit normal operation, can directly reduce again the temperature rise of radiator, fast reducing lamp interior temperature prolongs light fixture service life; In the situation that identical light fixture volume, select the led light source less than existing lamp power, can reach needed brightness, save power supply, also be suitable for and select the led light source higher than existing lamp power, lamp brightness is higher, and improves the comfort level of optical quality and illumination, widens the range of application of LED shot-light.
Description of drawings
Accompanying drawing 1 is the utility model perspective view;
Accompanying drawing 3 is the utility model radiator and fan structure schematic diagram.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment the utility model is explained in further detail.
Shown in accompanying drawing 1-3, a kind of LED shot-light, comprise the gland 1 of installing successively, radiator 5, lampshade 7 and lamp holder 8, between gland 1 and radiator 5, be provided with LED lens 2, led light source 3 and aluminium base 4, between radiator 5 and lampshade 7, be provided with circuit board 6, on the circuit board 6 power supply driver is installed, led light source 3 is installed on the aluminium base 4, aluminium base 4 is installed in the radiator 5, circuit board 6 is connected in lampshade 7 inside by fixture, and fixture can be screw, and gland 1 is fixed in LED lens 2 in the radiator 5, be provided with louvre 71 at lampshade 7,3 work of power supply driver driving LED light source.
In this example; be provided with turbine-like radiating groove 51 in radiator 5 fronts; be provided with the heat dissipation wind channel 52 of whirlwind shape at radiator 5 back sides; radiating groove 51 is positioned at radiator 5 place that keeps to the side; between lampshade 7 inner radiators 5 and circuit board 6, be provided with fan 9; fan 9 is connected with circuit board 6 by circuit, also is provided with the temperature protection switch 10 that is connected with circuit board 6 on aluminium base 4.
After the light fixture work, fan 9 starts work immediately, suck nature cold wind from the louvre 71 of lampshade 7, radiator 5 is carried out active heat removal, then by cyclone channel hot blast is blown out outside the lamp body, can reduce like this operating temperature of power supply driver, effectively guarantee the drive unit normal operation, can directly reduce again the temperature rise of radiator, fast reducing lamp interior temperature prolongs light fixture service life.
After light fixture is effectively worked certain hour, if damaging, fan 9 arrives in other words its lifetime limitation and cisco unity malfunction, this moment, the temperature of lamp radiator 5 can raise gradually, and after being raised to certain setting value, the temperature protection switch 10 of pressing close to it is subject to induction will automatic disconnection; This moment, light fixture also quit work thereupon, can not only effectively protect like this led light source 3 can not prevent that more whole light fixture from causing the generation of security incident because temperature rise is too high because excess Temperature damages, for follow-up light fixture maintenance provides reliable guarantee.
