Description

The LED luminous plaque

Technical field

The utility model relates to a kind of illuminator, specifically refers to a kind of luminous plaque of the LED of having wafer.

Background technology

Because LED environmental-protection, energy-conservation and long service life, sufficient brightness, thereby be widely used in each field.As common energy-saving lamp with the tubular light fitting of single LEDs wafer, be often used as the indicator lamp of relative low energy, but the former is because of the existence of bulb, very easily causes the appearance of broken phenomenon.And the latter is because be spot light, and light is comparatively dazzling, and brightness can't reach the requirement of standard illuminants product.For this reason, people want on printed substrate to place a plurality of LED wafers and overcome above-mentioned defective, but the LED wafer intensive after, in use can produce a large amount of heats, if this heat can't obtain distributing effectively in time, the functional reliability that causes light fixture is low, that service life is short drawback.Thereby when actual fabrication, the comparatively evacuation that the LED wafer on printed substrate is arranged, even if but like this, it is soft inadequately also to exist light, and total brightness is not high, and can't satisfy the illuminance requirement in some places.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, and a kind of perfect heat-dissipating, light is soft, brightness is high LED luminous plaque are provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this LED luminous plaque comprises substrate, be used to receive first of input voltage, second electric conductor and a plurality of mutual electrical connection also are connected in first, LED wafer between second electric conductor, it is characterized in that: described substrate is an aluminium matter heat-radiating substrate, described first, second electric conductor is printed on the upper surface of this aluminium matter heat-radiating substrate by insulating cement, on this aluminium matter heat-radiating substrate upper surface, also be fixed with a circle aluminium matter heat radiation wall simultaneously by insulating barrier, above-mentioned each LED wafer is enclosed in this aluminium matter heat radiation wall and is fixed on successively on the described aluminium matter heat-radiating substrate, and is filled with on each LED wafer by the described aluminium matter heat radiation optical cement that wall kept off.

In order to have better radiating effect, lower surface at aluminium matter heat-radiating substrate can be designed to the roughness structure to increase area of dissipation, consider the convenience of processing simultaneously, this roughness structure can be formed by a plurality of grooves that are opened in equably on the aluminium matter heat-radiating substrate lower surface, this groove can adopt the form of elongated slot, also can use the circular depressions form.

Described insulating barrier is made up of the heat conductive insulating glue-line that covers the insulation oil reservoir on the electric conductor and be positioned on the insulation oil reservoir, makes that the insulating properties between aluminium matter heat radiation wall and each electric conductor are better.

Described a plurality of LED wafer can be divided into some groups of LED wafers, and each organizes between the LED wafer parallel with one another, and series connection mutually between the LED wafer in each group.But preferably adopt the form that a plurality of LED wafers are connected in series mutually, in the use, help reducing the heat that luminous plaque produces like this.

In order to satisfy each light fixture needs, above-mentioned aluminium matter heat-radiating substrate can be designed to strip, also can be designed to circular configuration.Certainly, also can be designed to other shape as required.Corresponding, the shape of a circle aluminium matter heat radiation wall and the arrangement mode of each LED lamp also will be made corresponding variation.

Compared with prior art, advantage of the present utility model is to utilize dexterously the characteristics of aluminium matter heat-radiating substrate and aluminium matter heat radiation frame good heat-transfer, and by means of the LED bottom of wafer and all around simultaneously the heat radiation structure, make the utility model overcome defective of the prior art, and has the advantage of perfect heat-dissipating, thereby can be the LED wafer that distributes thick and fast on the substrate and created condition, and it is soft to obtain a light, high and the energy-conservation light source of brightness, such luminous plaque also has the fragmentation of being difficult for simultaneously, can make the advantage of different shape as required, to satisfy the installation needs of different lamps, thereby the utlity model has stronger practicality, be worth extensive use in existing light fixture.
