Description

The combined LED Tunnel Lamp

Technical field

The utility model relates to a kind of LED Tunnel Lamp, definite a kind of LED Tunnel Lamp that is formed by some low thermal resistance LED light source module unit combination of saying so.

Background technology

Many combined types of existing LED Tunnel Lamp or high-power module type all are earlier led chip to be fixed in metal heat sink again by silica gel encapsulation formation led light source, led light source is fixedly connected on radiator heat-dissipation, smear thermal grease conduction or heat-conducting cream between light source and radiator base plate to improve heat conductivility, heat is propagated to be lost to the environment from led chip in this case needs through chip → crystal-bonding adhesive → thermosphere → adhesive glue → radiator → environment, and we know that pilot process is many more, the long more heat radiation of passage is also just difficult more.

Summary of the invention

Above-mentioned led chip heat dissipation channel is long in order to solve, heat radiation is not smooth and the relatively-stationary problem of version, the utility model provides a kind of and led chip directly is fixed on radiator base plate has been packaged into the light source module unit again, then the LED Tunnel Lamp that is become by plurality of modules unit fixed combination.

The technical solution of the utility model is as follows:

The combined LED Tunnel Lamp, constitute by low thermal resistance LED light source module unit, driving power and fixed frame, some low thermal resistance LED light source module unit cell arrangement are fixed in fixed frame forms array of source, input direct current or alternating current connect each low thermal resistance LED light source module unit respectively behind the driving power rectifying and voltage-stabilizing, connected mode is series connection or in parallel.

Described low thermal resistance LED light source module unit is made of low thermal resistance LED light source module and light-distribution lens; Low thermal resistance LED light source module is made up of radiator, support, led chip, lead, fluorescent material, electrode and casting glue, led chip directly is anchored on by solid crystal technique and forms array arrangement on the radiator base plate, each chip chamber connects by the lead serial or parallel connection, around the chip and top portion be furnished with phosphor powder layer, led chip, lead and fluorescent material are encapsulated by casting glue; Light-distribution lens is installed in the low thermal resistance LED light source module exiting surface.

Described radiator is made by the contour heat conduction alloy material of copper, aluminium or magnesium, comprise fin and substrate, the substrate chip encapsulation region is planar structure or cavernous structure, and do silver-plated processing in this regional extent or be provided with silver-colored line layer structure, can arrange many power-type LED chips in the encapsulation region simultaneously to realize encapsulation ultra-large type power LED light source.

Radiator can be fin type, pin configuration or perforation grid type, and the chip that pin configuration radiator changes the fin type fin is aciculiform or cylindricality, and array is distributed in substrate then; Perforation grid radiator middle part is substrate and chip encapsulation region, and it is netted that its peripheral fin forms staggered perforation of intersecting, and fin can be plane or curved surface.

Described driving power is AC/DC or DC/DC constant current source of stable pressure, and output voltage and power and led light source coupling are anchored on fixed frame after the driving power encapsulation process.

Described fixed frame is generally the high material mold pressing of metal material or other mechanical strengths or is welded, and it is provided with the attaching parts of fixedly connected low thermal resistance LED light source module unit and driving power.

Described light-distribution lens is by glass or resinous material compression molding.

Good effect of the present utility model: changed in the past led chip and be fixed in metal heat sink earlier and be packaged into led light source and be connected in the fixed mode that radiator carries out the secondary heat radiation by heat-conducting silicone grease then, the utility model low thermal resistance LED light source module led chip directly is anchored on by solid crystal technique and forms array arrangement on the radiator base plate, excessive layer in the middle of reducing, shorten heat dissipation channel, can reduce the LED junction temperature greatly under the equal conditions; The heat-radiating integrated modular unit of luminous intensity distribution can be realized the changeability of LED Tunnel Lamp power strengthening flexibility by the combination of some.
