Description

The LED Ceiling light that a kind of luminous Homogeneouslly-radiating is good

Technical field

The utility model discloses the structure of the good LED Ceiling light of a kind of luminous Homogeneouslly-radiating, relate to technical field of semiconductor illumination.

Background technology

LED is a kind of green light source, compares with incandescent lamp, fluorescent lamp, and electric energy height not only, and environment do not polluted, but the heat dissipation problem that how to solve the LED light fixture is an important technology bottleneck that influences its performance.

The LED light fixture mainly is made up of led light source, radiator structure, driver, lens or reflector, existing LED light fixture solves the heat dissipation problem of LED, take the temperature on the chip is led on the aluminium base, perhaps in order to increase area of dissipation, utilize bigger aluminium section bar of area of dissipation and aluminium base to link together again and carry out secondary heat conduction, the effect that distributes with the PN junction heat that reaches LED.But present LED Ceiling light has individual common feature, be exactly led light source, radiator structure, driver, lens or reflector, the three exists in the same cavity, might after lighting LED, solve heat dissipation problem, but after lighting for a long time, the heat that LED discharges can exert an influence to driving electrical equipment, is the circuit working state instability, the electric current output pulsation is bigger, thereby has a strong impact on the service life of led light source.

The utility model content

The technical problems to be solved in the utility model provides the good LED Ceiling light of a kind of luminous Homogeneouslly-radiating.Not only make large-power light-emitting diodes can access good heat radiation, and make the LED Drive and Control Circuit not be subjected to its temperature effect.

For addressing the above problem, the utility model LED Ceiling light comprises electrical equipment box link cover of FIG 1, electrical equipment box upper casing 2, driver 3, electrical equipment box lower casing 4, radiator 5, led light source assembly 6, lens subassembly 7, interior lamp ring 8, shell fragment 9, outer lamp ring 10, support cylinder 11.Outer lamp ring 10 is enclosed within outside the interior lamp ring 8, both flexibly connect by support cylinder 11, be provided with lens subassembly 7 in the interior lamp ring 8, led light source assembly 6 places the bottom of lens subassembly 7, and radiator 5 is horn-like for sealing, and two ends are connected with electrical equipment box lower casing 4 with outer lamp ring 10 respectively, form 3 separate cavitys, driver 3 is fixed on the electrical equipment box lower casing 4, and power line inserts led light source assembly 6 and forms the circuit connection after driver 3 conversions.It is characterized in that: the light source of this LED Ceiling light, radiator and electrical equipment are present in an independent cavity separately, electrical equipment does not directly contact with radiator, avoid heat that radiator sends to the influence that electrical equipment causes, improved the stability of electrical equipment, prolonged the service life of electrical equipment simultaneously.The design of this LED Ceiling light is used, by the structure that several light sources place same lens is set, interior lamp ring (8) inside is provided with the anti-dazzle ring of light ring of light phenomenon that the LED lamp occurs is usually eliminated, and makes the light issue evenly, has improved the illumination uniformity in the effective lighting scope; Can play the anti-dazzle effect, improve the application efficiency of LED light fixture again; The outer lamp ring (10) of LED Ceiling light can rotate to an angle with radiator (5) as required with interior lamp ring (8) and interior lamp ring (8) in addition, simultaneously, this LED equivalents have also that volume is little, in light weight, caloric value is little, luminous efficiency is high, LED long service life, energy-conservation remarkable result.

Described lens 7-1 is that the lens unit that has independent optical function constitutes, and material is PC or PMMA.

The material of described radiator 5, shell fragment 9, support cylinder 11 is high duty metal or alloy material.

Described electrical equipment box link cover of FIG 1, electrical equipment box upper casing 2, electrical equipment box lower casing 4, lens case 7-2, interior lamp ring 8, outer lamp ring 10 materials are high temperature resistant, corrosion-resistant, the high-intensity high molecular synthetic material with high heat dispersion.
