Abstract

The utility model discloses a high-power patch plane light source. The high-power patch plane light source is characterized by being composed of two positive and negative pole power source connection points, a support bottom PCB, a luminous body and connection lines; the luminous body is fixed to the support bottom PCB; the two positive and negative pole power source connection points are arranged on the two sides of a support respectively; the luminous body is connected with the positive and negative pole power source connection points through the connection lines. An external power source is in butt joint with the positive and negative pole power source connection points, a chip of the luminous body gives out light, and after the light reaches fluorescent powder mixed with silica gel and the bottom of the support, light reflection is formed at the bottom of the support and more light is produced; at the moment, as the electric light energy of the chip is converted incompletely, heat energy is generated and is conducted to the outside of a product instantly by the bottom (made of light reflection metal materials) of the support, and the service life of the product is prolonged; the plane type packaging is adopted, no lens is used, the brightness is higher than that of a light source with a lens, reflow soldering can be achieved, and coefficients of heat dissipation and heat conduction are higher.

Description

High-power paster planar light source

Technical field

The utility model relates to lighting apparatus, and especially high-power paster planar light source, belongs to technical field.

Background technology

At present the LED light source of use be exactly light emitting diode (LED) be the light source of illuminator.Light emitting diode was invented the sixties in 20th century, and in many decades subsequently, its basic purposes is the indicator lamp as electronic equipments such as radio cassette players.This bulb has the advantages that efficiency is high, the life-span is long, can use continuously 100,000 hours, than long 100 times of ordinary incandescent lamp bubble.Scientist's prediction, at the five-year, this bulb probably becomes the main product of illumination of future generation.

Yet nowadays the imitative lumen lamp pearl of the tradition of our use does not cross high temperature, does not particularly cross Reflow Soldering.Because traditional imitative lumen product, use be lens packages, cross Reflow Soldering and just occur dead lamp.

Utility model content

The purpose of this utility model is can cross in order to provide a kind of the high-power paster planar light source that Reflow Soldering, heat radiation thermal conductivity factor are higher, improve service life.

The purpose of this utility model can be by taking following technical scheme to reach:

High-power paster planar light source, is characterized in that: positive and negative power supply tie point, frame bottom PCB plate, illuminator and connecting line, consist of, described illuminator is fixed on frame bottom PCB plate; Described positive and negative power supply tie point is two, is located at the both sides of support; Described illuminator is connected to positive and negative power supply tie point by connecting line.

As a kind of preferred version, described illuminator is located at the middle position of frame bottom PCB plate.

The utility model has following beneficial effect with respect to prior art:

1, external power source docks positive and negative power supply tie point of the present utility model, illuminator chip light emitting, and light arrives and is mixed with after the fluorescent material and frame bottom of silica gel, thereby frame bottom forms light there is more light in reflection; The heat now not exclusively producing because of chip electricity transform light energy, by frame bottom (light reflective metals material), moment conducts the heat to the outside of product, thus the life-span of improving product;

2, the utility model adopts plane formula encapsulation, does not use lens, and brightness is also higher than lensed light source, can cross Reflow Soldering, and heat radiation thermal conductivity factor is higher;

3, the utility model can be used in above multiple light fixture, such as bulb lamp, lamp affixed to the ceiling, bread lamp, street lamp, Parchment lamp etc.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Wherein, 1-positive and negative power supply tie point, 2 frame bottom PCB plates, 3-illuminator, 4-connecting line.

The specific embodiment

Embodiment 1:

As shown in Figure 1, the high-power paster planar light source of the present embodiment, is characterized in that: positive and negative power supply tie point 1, frame bottom PCB plate 2, illuminator 3 and connecting line 4, consist of, described illuminator 3 is fixed on frame bottom PCB plate 2; Described positive and negative power supply tie point 1 is two, is located at the both sides of support; Described illuminator 3 is connected to positive and negative power supply tie point 1 by connecting line 4, then direct encapsulated moulding.

Preferably, described illuminator 3 is located at the middle position of frame bottom PCB plate 2, and directly sealing adopts plane formula encapsulation.

When using, external power source docks positive and negative power supply tie point 1 of the present utility model, illuminator 3 chip light emittings, and light arrives and is mixed with after the fluorescent material and frame bottom of silica gel, thereby frame bottom forms light there is more light in reflection; The heat now not exclusively producing because of chip electricity transform light energy, by frame bottom (light reflective metals material), moment conducts the heat to the outside of product, thus the life-span of improving product.

This light source adopts plane formula encapsulation, does not use lens, and brightness is also higher than lensed light source, can cross Reflow Soldering, heat radiation thermal conductivity factor is higher, and can be used in above multiple light fixture such as bulb lamp, lamp affixed to the ceiling, bread lamp, street lamp, Parchment lamp etc.

The above; it is only the utility model patent preferred embodiment; but the protection domain of the utility model patent is not limited to this; anyly be familiar with those skilled in the art in the disclosed scope of the utility model patent; according to the technical scheme of the utility model patent and utility model patent design thereof, be equal to replacement or changed, all being belonged to the protection domain of the utility model patent.
