CN203240335U - LED (light-emitting diode) light source device - Google Patents

The utility model discloses an LED (light-emitting diode) light source device, which comprises a lamp body and a lamp holder which is arranged on the lamp body, wherein the lamp holder comprises a radiator, a reflective cup and a plurality of LED chips which are dispersedly arranged on the inner wall of the reflective cup, and the outer wall of the reflective cup is sleeved and connected with the radiator. According to the LED light source device disclosed by the utility model, the reflective cup is arranged, the LED chips are dispersedly arranged on the inner wall of the reflective cup, and the outer wall of the reflective cup is sleeved and connected with the radiator, so the LED chips can be far away from a power supply due to such a design, meanwhile, heat of the LED chips is dispersed, and the heat radiation speed is fast, so that the phenomena that other electronic elements in the lamp body are damaged or the service lives of the other electronic elements in the lamp body are shortened due to high temperature can be avoided, and meanwhile, light attenuation of the LED light source is reduced.

The led light source device

Technical field

The utility model relates to the LED lighting field, relates in particular to a kind of led light source device.

Background technology

Led light source has that long service life, luminous utilization rate are high, energy consumption is low, luminous efficiency is high and also the advantage such as improving constantly, makes it become a kind of desirable green illumination light source.Along with the popularization of this lighting engineering in the whole world, the LED lamp will replace the products such as fluorescent lamp, electricity-saving lamp, incandescent lamp, welcomes brand-new illumination epoch.Existing LED lamp, illuminator is all concentrated the bottom that is positioned at lamp holder on the general structure, power supply in lamp body is closer, the easy like this led light source chip that causes is concentrated because of heat, be difficult for dispelling the heat and losing efficacy, perhaps the heat of illuminator concentrate on from power supply close to very around, cause power supply high temperature and life-span of reducing inner each electronic devices and components of power supply, thereby affect the service life of whole LED.

The utility model content

The utility model provides a kind of heat dissipation environment of led light source, led light source device that increases the service life of improving.

To achieve these goals, the technical solution scheme that the utility model proposes is: a kind of led light source device comprises lamp body and is installed in lamp holder on the lamp body; Described lamp holder comprises radiator, reflector and a plurality of led chip, and described a plurality of led chips disperse to be installed on the inwall of reflector, and described reflector outer wall is socketed described radiator.

Wherein, described led chip is circle-shaped even distribution along the reflector inwall.

Wherein, described led chip comprises LED light pearl and substrate, and pearl is installed on the substrate LED light; Described substrate is provided with through hole and contact head, and described reflector is provided with screw and electric jack, and described contact head is adaptive is plugged in the electric jack and a screw is adaptive passes through hole and the screw fixing base that is spirally connected.

Wherein, described substrate is provided with an angular zone, and this angular zone is adaptive to be contacted with cup described reflector the end, and described through hole and contact head are positioned on the angular zone of described substrate.

Wherein, the one side of described substrate mounted LED lamp bulb scribbles reflective material.

Wherein, be provided with heat-conducting glue between described substrate and the reflector, be provided with heat-conducting glue between reflector and the radiator.

Wherein, the cup end of described reflector, be set to reflective surface.

The beneficial effects of the utility model are: the led light source device that is different from prior art, the led chip concentrated setting, heat is concentrated, be difficult for the problems such as heat radiation, led light source device of the present utility model, be provided with reflector, led chip disperses to be installed on the inwall of reflector, the reflector outer wall is socketed described radiator, and this design can make led chip away from power supply, simultaneously so that the spread heat of led chip and heat radiation are quick, high temperataure phenomena can not appear, damage other electronic components in the lamp body, or shorten other electronic components service life in the lamp body, reduce simultaneously the light decay of led light source.
