Abstract
A light-emitting diode (LED) signal light device with a heat radiation base belongs to the field of signal light devices. The LED signal light device with the heat radiation base includes an LED body, a light cover, a base and a power supply connector arranged at the bottom of the base of the light. The light cover is in fixed connection with the light base, and the LED body is disposed in the light cover. The LED body comprises at least a strip LED and a substrate, and the strip LED is welded on the substrate. The substrate is in fixed connection with the base of the light. The LED signal light with the heat radiation base is characterized in that the bottom of the base is provided with a plurality of parallel strip heat radiation grooves. The problem of poor heat radiation, poor reliability, and short service life existing in the prior art is resolved.
Description
Technical field
The utility model relates to a kind of signal lamp device, particularly a kind of LED signal lamp device with heat radiation lamp socket.
Background technology
The LED light fixture has or not advantages such as delay, low power consuming, life-span length, makes the illumination of LED use more and more wider.Yet the photoelectric transformation efficiency value of LED lamp is still limited, and 15～25% the input power of generally only having an appointment transforms into light, and all the other convert heat energy to.Because the very little (～1mm of LED chip area
2), so the caloric value of LED lamp unit are is very high, causes wafer to connect surface temperature and sharply raises, luminous efficiency seriously descends.In addition, too high wafer connects surface temperature can make the luminosity of LED reduce, wherein obvious with the decay of ruddiness, also can cause the wavelength shift of LED and influences color rendering, more can cause the significantly reduction of LED signal reliability.Though and existing LED signal lamp considers that not too radiating effect has some products to adopt the common metal heat radiation, radiating effect is poor, has limited the advantage of LED equivalent life length and good reliability.
Therefore heat dissipation technology has become the bottleneck of present LED technical development.
The utility model content
In order to overcome the defective that above-mentioned field exists, the utility model provides a kind of LED signal lamp device with heat radiation lamp socket, and the technical scheme that is adopted is:
LED signal lamp device with heat radiation lamp socket, comprise LED body, lampshade, lamp socket and be positioned at the power connector of lamp socket bottom, described lampshade lamp socket is fixedly connected, described LED body places in the lampshade, described LED body is the substrate that is welded with paster LED on the surface, described substrate is fixedly connected on the described lamp socket, it is characterized in that, described lamp socket bottom is provided with the bar shaped radiating groove that plural number is arranged in parallel.
Be welded with drive circuit on the described substrate simultaneously.
The material of described substrate and lamp socket is an aluminium alloy.
Scribble heat-conducting silicone grease on described substrate and the face that lamp socket is connected.
Be connected for screw between described lampshade and the lamp socket.
Be connected for screw between described substrate and the lamp socket.
The tip of screw that connects lampshade and lamp socket stretches out from the lamp socket bottom, and extended position is provided with seal I.
The junction is provided with sealing ring between described lamp socket and the lampshade.
The position that described lamp socket links to each other with power connector is provided with seal II.
The utlity model has the LED lamp device of heat radiation lamp socket, the beneficial effect that adopts technique scheme to obtain is: the lamp socket bottom is provided with the bar shaped radiating groove, not only enlarged area of dissipation, and help cross-ventilation, improved heat dissipation environment greatly, increase the reliability of LED lamp, and prolonged its service life.
Led drive circuit and LED evenly arrange and are welded on the aluminium base, adopt drive circuit, LED integrated, reduce to connect, and have improved the reliability of device, and installation and maintenance are flexible.
Substrate and lamp socket adopt aluminum alloy materials to replace common metal, and radiating effect is better.
Each junction is equipped with seal, and waterproof is dustproof, improves service life, can satisfy the requirement of various environments for use.
