Abstract

The utility model discloses an embedded LED flat panel light source, which comprises a lamp cap connected with a power supply, a driver board used for driving an LED lamp, a diffuser and a heat conductor arranged between the lamp cap and the diffuser, wherein the heat conductor comprises an upper heat conductor and a lower heat conductor, a gap is left between the upper heat conductor and the lower heat conductor, the upper heat conductor and the lower heat conductor are mutually spliced with each other though a plurality of connecting rods, the driver board and a baseplate with the LED lamp are respectively arranged on the end surfaces of the upper heat conductor and the lower heat conductor, which are departed from each other, and the connecting rods are respectively arranged on the opposite end surfaces between the upper heat conductor and the lower heat conductor. The utility model has good heat dissipation effect, convenient component replacement, long service life and the like.

Description

The embedded LED planar light source

Technical field

The utility model relates to light fixture, relates in particular to a kind of LED planar light source.

Background technology

The structure of existing LED planar light source generally includes: the lamp holder 1 that joins with power supply, the drive plate that is used for the driving LED lamp, diffuser 4 is installed in the heat carrier that is used for dispelling the heat between lamp holder and the lampshade, LED lamp 2 generally is attached to the heat-conducting substrate 9 that joins with heat carrier 8, on aluminum base plate.Because the LED lamp quantity of using is more, the most direct factor that influences the use of LED planar light source is its radiator structure, the effect of heat carrier in the LED planar light source is most important, existing heat carrier is generally heat conductivility preferred metal material or alloy material is made, with in time, fully conduct, distribute the heat that LED lamp and drive plate produce, guarantee the long-term operate as normal of LED planar light source.

The major defect of existing LED planar light source is: the 1.LED planar light source in the course of the work, drive plate is two different thermals source with the LED lamp, use all-in-one-piece heat carrier that the heat of drive plate and the generation of LED lamp is absorbed, radiating effect is not very good; 2. in the actual use, drive plate and LED lamp are also not quite identical, and one of them needs integral replacing if any damage, safeguard inconvenient.

The utility model content

The purpose of this utility model provides a kind of embedded LED planar light source, is intended to solve the defective that the heat radiation of LED planar light source is insufficient in the prior art, maintenance is inconvenient.

The embedded LED planar light source that the utility model provides, comprise the lamp holder that joins with power supply, the drive plate that is used for the driving LED lamp, diffuser, be installed in the heat carrier between lamp holder and the diffuser, it is characterized in that: described heat carrier comprises heat carrier and following heat carrier, leaves the space between the described upper and lower heat carrier and is plugged on mutually together by many connecting rods, and described drive plate, the substrate that has a LED lamp are installed in respectively on the end face that upper and lower heat carrier deviates from mutually.

Further, described each connecting rod is installed between the upper and lower heat carrier on the opposing end faces.

The embedded LED planar light source that the utility model provides because heat carrier branch of the prior art is set as upper and lower heat carrier, leaves the gap that can ventilate between the upper and lower heat carrier, radiating surface is bigger, therefore, and distribute heat more effectively; Peg graft mutually by many connecting rods between the upper and lower heat carrier, drive plate, LED lamp are installed in upper and lower heat carrier respectively, therefore, when parts damages in drive plate or the LED lamp, can change separately, safeguard more convenient.

Fig. 1 is the overall structure schematic diagram of a kind of embedded LED planar light source described in the utility model;

Fig. 2 is the decomposition texture schematic diagram of a kind of embedded LED planar light source described in the utility model;

Fig. 3 is the decomposition texture schematic diagram of a kind of embedded LED planar light source described in the utility model.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.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.

With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of embedded LED planar light source, comprise the lamp holder 1 that joins with power supply, the drive plate 3 that is used for driving LED lamp 2, diffuser 4 is installed in the heat carrier between lamp holder and the diffuser, maximum different being of the utility model and prior art, the heat carrier branch is set as heat carrier 5 and following heat carrier 6, leaves the space for heat radiation, ventilation between the described upper and lower heat carrier, the distance that 5 millimeter generally can be arranged in the gap is comparatively suitable; The setting in this gap makes two relative between upper and lower heat carrier end faces also become radiating surface, and therefore, radiating effect significantly promotes; Better heat radiating effect also can significantly improve service life of the present utility model.

Then be plugged on mutually together between the upper and lower heat carrier of the present utility model, become a kind of mutual Embedded LED planar light source, upper and lower heat carrier can be dismantled by many connecting rods 9;

Drive plate

3,7 of substrates that have a LED lamp 2 are installed in respectively on the end face that upper and lower heat carrier deviates from mutually, like this, the heat that two parts of drive plate and LED lamp produce is by different heat carrier heat radiations, and radiating mode is separate, and two heats that parts produced can not be superimposed.

Described each connecting rod 9 is installed between the upper and lower heat carrier on the opposing end faces, that is, and and between the built-in and upper and lower heat carrier, comparatively hidden, can not increase the occupation space of LED planar light source like this, significantly not change LED planar light source face shaping, improve versatility of the present utility model.

In actual the use, the LED planar light source life-span elder generation of drive plate often terminates, and at this moment, can stay and continue to use after the dismounting of LED lamp part, and replacing, maintenance are got up also more convenient.

Claims

1. embedded LED planar light source, comprise the lamp holder that joins with power supply, the drive plate that is used for the driving LED lamp, diffuser, be installed in the heat carrier between lamp holder and the diffuser, it is characterized in that: described heat carrier comprises heat carrier and following heat carrier, leaves the space between the described upper and lower heat carrier and is plugged on mutually together by many connecting rods, and described drive plate, the substrate that has a LED lamp are installed in respectively on the end face that upper and lower heat carrier deviates from mutually.

2. embedded LED planar light source according to claim 1 is characterized in that: described each connecting rod is installed between the upper and lower heat carrier on the opposing end faces.
