Abstract

The utility model relates to an integrated waterproof LED lamp plate which comprises a reflection baseplate. The baseplate is provided with a groove in which LED lamps are placed to form a reflection cavity; the LED lamps are connected together by circuits; the baseplate is covered with a transparent insulating layer on which a transparent filling and sealing layer is arranged for filling and sealing other layers together. A diffusion layer is stamped on the transparent filling and sealing layer which is covered by a transparent protection layer. The integrated waterproof LED lamp plate has the advantages of waterproof, dustproof, crumpling-resistance, anti-friction and corrosion-resistance performances, high luminous efficiency, excellent radiating effect, but low heat productivity, low cost, and no apparent bright spot and black space. The integrated waterproof LED lamp plate uses the rectangular matrix of LED to emit light which is diffused by the diffusion layer; and refracted light source is reflected to further increase the brightness of emitted light.

A kind of integrated water-proof LED lamp plate; comprise reflective substrate; fluted on the substrate; the LED lamp is placed on and forms reflection cavity in the groove; circuit connects between the LED lamp, spraying layer of transparent insulating barrier on substrate, and embedding one deck is the transparent embedding layer of one with above-mentioned each layer embedding on the transparent insulating layer; stamp diffusion layer above the transparent embedding layer, add a cover protective clear layer above.

The dentation reflector is set between the above-mentioned reflection cavity, and reflector is positioned at below the embedding layer.

Reflective substrate is to adhere to one deck reflecting layer or the combination of aluminium alloy or plastics and aluminium alloy above the plastic material, and described reflecting layer is the metal-plated rete.

Reflecting metal plated film layer is the vacuum plating silver layer.

Diffusion layer is that fluorescent material and transparent resin or transparent silica gel mix.

Diffusion layer is the reflective printing ink of one deck site of making at least.

One of protective clear layer transparent resin, transparent silica gel or fluorescent material and transparent resin, transparent silica gel mix.

Transparent insulating layer is one of transparent resin, transparent silica gel or its combination.。

The circuit part of LED lamp and circuit is formed by one of conducting metal nation alignment, metal forming or its Combination Welding.

Described protective clear layer is transparent epoxy or silica gel material.The beneficial effects of the utility model are: this apparatus integration Waterproof LED lamp plate, provide that a kind of caloric value is little, waterproof and dustproof, anti-extruding, shock-resistant, wear-resisting wiping, a series of advantage such as corrosion-resistant, have luminous efficiency height, no obvious bright spot and dark space, good heat dissipation effect, characteristics that cost is low.Integrated water-proof LED lamp plate is by the luminous transparent insulating layer that sees through of LED matrix, and via the reflective site diffusion of corresponding LED matrix, refract light source has further been strengthened emitting brightness by the reflection of reflective metals rete.As use aluminium alloy plate as substrate, and transparent epoxy resin silica gel is hyaline layer and protective layer, integrated water-proof LED lamp plate just can accomplish that caloric value is little, waterproof and dustproof, anti-extruding, shock-resistant, wear-resisting wiping, a series of advantage such as corrosion-resistant.

The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

This apparatus integration Waterproof LED lamp plate, provide that a kind of caloric value is little, waterproof and dustproof, anti-extruding, shock-resistant, wear-resisting wiping, a series of advantage such as corrosion-resistant, have luminous efficiency height, no obvious bright spot and dark space, good heat dissipation effect, characteristics that cost is low.

Embodiment 1: integrated water-proof LED lamp plate is made of substrate 1, reflective metals rete 2, insulation transparent layer 3, LED matrix and circuit, power supply lead-in wire, diffusion layer 6, protective clear layer 7.

Substrate is one of plastics, aluminium alloy or its combination, and shape is that optically focused reflection cavity 11, reflective metals rete 2, the side reflector of corresponding LED matrix combines.

In the optically focused reflection cavity 11 of corresponding LED matrix one or more LED can be arranged.

Reflective metals rete 2 is to be plated on the substrate by reflecting metal.

Transparent insulating layer 3 is one of transparent resin, transparent silica gel or its combination.

Transparent insulating layer is inserted at least at twice.

The LED lamp 43 of LED matrix and circuit places the optically focused reflection cavity of corresponding LED matrix.

The circuit part of LED matrix and circuit is formed by one of conducting metal nation alignment 41, metal forming 42 or its Combination Welding.

Diffusion layer 6 is that fluorescent material and transparent resin or transparent silica gel mix.

Perhaps diffusion layer 6 is one deck light guide ink sites of making at least.

Protective clear layer 7 is mixed by one of transparent resin, transparent silica gel or fluorescent material and transparent resin, transparent silica gel.

Preparation method: example 1

Substrate 1 is by minute surface aluminium sheet (aluminum alloy materials), be cast into Fig. 1 a shape, in conjunction with Fig. 1 b, spraying layer of transparent insulating barrier 3, insert LED lamp 43 in substrate 1 reply, constitute the metal-foil circuits part by the FPC FPC, the FPC of LED lamp places on the substrate 1, plates reflector layer in the circuit board, surely weld by alignment nation of metal nation, the good electric loop of welding lead-in wire, as Fig. 2 a, the energising test.With reference to Fig. 2 b, embedding transparent epoxy layer 5, vacuum row bubble, heating cure stamps reflective printing ink site as diffusion layer 6, adds a cover protective clear layer 7, makes finished product, as Fig. 3 a and Fig. 3 b.

Because high-quality minute surface aluminium sheet just was coated with metal level originally, so this example does not have the reflecting metal plated film.The product height is 4 millimeters in this example.Distance is 10 millimeters between the LED, the circuit part of LED matrix and circuit mixes use by conducting metal nation alignment, metal forming in this example, constitute the metal-foil circuits part by the FPC FPC and can make the circuit of relative complex, can place a plurality of LED for the optically focused reflection cavity of corresponding LED matrix electric loop is provided.
