Abstract

The utility model relates to a high power light emitting diode (LED) surface light source, which comprises a plurality of high power LED lamp beads, a metal heat dissipation plate and a constant current power, wherein the high power LED lamp beads are adhered on the metal heat dissipation plate through glue, and are connected through wires, connecting positions of pins and the high power LED lead beads and the wires are packed by insulation tubes and are insulated with the metal heat dissipation plate, the wires between the high power LED lamp beads pass through small holes which are arranged on the metal heat dissipation plate, and are arranged on the back surface of the metal heat dissipation plate, and the constant current power is arranged on the metal heat dissipation plate and is connected with the high power LED lamp beads to be a power supply circuit. The high power LED surface light source has the advantages of energy conservation, excellent heat dissipation effect, small degradation, long life and convenient manufacture.

Description

A kind of high-power LED surface light source
Technical field
The utility model belongs to a kind of high-powered LED lamp of lighting technical field, especially LED area source.
Background technology
High-powered LED lamp, than conventional light source, has energy-conservation, lightweight, the advantage such as volume is little, the life-span is long, environmental protection, belongs to new generation of green light source.But, if the heat of great power LED does not shed in time, will cause its lost of life, luminous efficiency reduces, and finally scraps.Nowadays the multiplex low-power LED of the most of LED light fixtures on market is made, and brightness is on the low side, and cost is higher.Great power LED (more than 1 watt) sufficient brightness is to reach illuminating effect, but the high-power LED lamp of selling on the market mostly at present is the form of ball bubble and fluorescent tube, and heat dissipation problem is difficult to solve.
Utility model content
The purpose of this utility model is to provide a kind of good heat dissipation effect, simple in structure, high-power LED surface light source easy to make, and guarantee its working life of 50,000 hours.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of high-power LED surface light source, comprise many large-power LED light beads, metallic heat radiating plate, constant-current source, described large-power LED light bead by glue bond on described metallic heat radiating plate, between described many large-power LED light beads, with wire, connect, insulate with insulation tube parcel and with described metallic heat radiating plate in the pin of described large-power LED light bead and the junction of wire, wire between described large-power LED light bead is through being arranged on the aperture on described metallic heat radiating plate, and be placed in the described metallic heat radiating plate back side, described constant-current source is placed on described metallic heat radiating plate and with described large-power LED light bead and connects into current supply circuit.
This programme at least has the following advantages: with heat-conducting glue or heat conductive pad, large-power LED light bead is bonded on metallic heat radiating plate, reduce the aluminium base in current LED light fixture, reduced cost, reduced thermal resistance, be conducive to improve radiating efficiency, the arrangement of LED simultaneously has very large flexibility.It is attractive in appearance that described constant-current source and lead placement are conducive to light fixture at the described metallic heat radiating plate back side.
According to the utility model of said structure, its beneficial effect is, has not only effectively solved heat dissipation problem, has improved photoelectric transformation efficiency.And, because LED lamp pearl is only settled in the front of metallic plate, greatly given prominence to attractive in appearance, generous, the succinct feature of this high-power LED surface light source.
Accompanying drawing explanation
Fig. 1 is the utility model Facad structure schematic diagram.
Fig. 2 is the utility model structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
As shown in Figure 1, for Facad structure schematic diagram of the present utility model, this high-power LED surface light source, comprise metallic heat radiating plate 1, wire 2, heat-shrink tube 3, large-power LED light bead 4, aperture 5, described large-power LED light bead 4 back sides are bonded on metallic heat radiating plate 1 by heat-conducting glue, the wire 2 being connected with the pin of large-power LED light bead 4 passes the back side that is placed in metallic heat radiating plate 1 from aperture 5, heat-shrink tube 3 parcels for the junction of the pin of large-power LED light bead 4 and wire 2.
Shown in Fig. 2, be structure schematic diagram of the present utility model, the wire 2 passing from aperture 5 is connected to constant-current source 6, and then can be connected with constant-current source easily.
In a word, the above, be only preferred embodiment of the present utility model, is not used for limiting the utility model range of application.Be that all equalizations of doing according to the utility model claim change and modify, all in the scope of the claims of the present utility model.
