Abstract
The utility model is applicable to the technical field of lighting and provides an LED light source and an LED lighting device. The LED light source comprises a support and a plurality of LED chips, wherein the LED chips are subjected to crystal solidification and wire soldering on the support. A heat radiation solder pad is arranged at the bottom of the support. Since the heat radiation solder pad is arranged at the bottom of the support, heat radiation conduction paths of the LED chips are added, heat radiation capability of the LED light source is greatly enhanced, the LED chips can operate at the lower temperature and accordingly, the service life of the LED light source is guaranteed.
Description
Technical field
The utility model belongs to lighting technical field, relates in particular to a kind of led light source and LED lighting device.
Background technology
Many weeks, LED is as the new generation of green lighting source, has numerous advantages such as light efficiency height, life-span are long, bright in luster, energy-saving and environmental protection, and application is more and more widely grown like indoor and outdoor lighting, backlight, medical treatment, traffic, plant etc.
The energy-conserving and environment-protective theory is advocated in the whole world makes LED become irreversible trend, and the LED lighting device will little by little replace present incandescent lamp and electricity-saving lamp.Yet existing led light source poor heat radiation influences its service life.
The utility model content
The purpose of the utility model embodiment is to provide a kind of led light source, is intended to solve the problem of existing led light source poor heat radiation.
The utility model embodiment is achieved in that a kind of led light source, comprises that support and solid crystalline substance are wired in a plurality of led chips of said support, and the bottom of said support is provided with the heat radiation pad.
Another purpose of the utility model embodiment is to provide a kind of LED lighting device, and said LED lighting device adopts above-mentioned led light source.
The utility model embodiment establishes the heat radiation pad in the bottom of support, has increased the heat radiation conducting path of led chip, has greatly promoted the heat-sinking capability of led light source, makes led chip work in lower temperature, has guaranteed the service life of led light source.

The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model embodiment establishes the heat radiation pad in the bottom of support, has increased the heat radiation conducting path of led chip, has greatly promoted the heat-sinking capability of led light source, makes led chip work in lower temperature, has guaranteed the service life of led light source.
Be described in detail below in conjunction with the realization of specific embodiment the utility model.
Shown in Fig. 1～4, the led light source that the utility model embodiment provides comprises that support 1 and solid crystalline substance are wired in a plurality of led chips 2 of said support 1, and the bottom of said support 1 is provided with heat radiation pad 11.Said heat radiation pad 11 has increased the heat radiation conducting path of led chip 2, has greatly promoted the heat-sinking capability of led light source, makes led chip 2 work in lower temperature, has guaranteed the service life of led light source.
Particularly, said support 1 is made up of the substrate 12 of the solid said led chip 2 of brilliant bonding wire and the reflector 13 that is fixedly arranged on said substrate 12, and said heat radiation pad 11 is located at the lower surface of said substrate 12.The heat of led chip 2 generations conducts to heat radiation pad 11 through substrate 12 like this, and the heat conduction is more direct, and it is faster to dispel the heat.
A plurality of led chips 2 insert positive terminal pad 14 and negative terminal pad 15 respectively after being connected in series successively, and said positive terminal pad 14 and negative terminal pad 15 lay respectively at the both sides of said heat radiation pad 11, and adjacent two pads are separated by insulator 16.Be convenient to the user like this and weld this led light source, solve the problem of power supply design aspect simultaneously for the client, it is very convenient to operate.Wherein, said heat radiation pad 11 is preferably copper heat radiation pad.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
