Description
Technical field
The utility model belongs to the solid-state illumination technical field, specially refers to the plate shape illuminating lamp consisted of several many Lamp cups and solid state light emitter, relates to heat radiation and reduces the dazzle technology.
Technical background
LED (solid state light emitter), due to energy-conserving and environment-protective, be considered to mankind's illumination light source of future generation, but it is universal to hinder the LED illuminating lamp, and the key obstacle that replaces the traditional lighting lamp is: the cost of LED illuminating lamp is too high.The cost of LED illuminating lamp can be divided into three parts: LED light source, power supply and structural member, structural member includes radiator, at present the cost of structural member accounted for the LED illuminating lamp totle drilling cost 1/3rd more than, the cost of LED light source is current prime cost, but decline space is at double arranged, thereby reduction structural member (radiator) cost will become the emphasis of realizing that LED is universal.
The light that LED chip sends, luminous flux density is very high, and people's eyes are directly being seen the light that LED chip sends, and can produce strong glare problem, existing a kind of plate shape LED illuminating lamp, adopt the backlight technology in liquid crystal display, application LGP wherein, penetrate the uniform plane ground that luminous energy is larger from an area, luminous flux density significantly descends, glare problem is solved at all, and slab structure is adapted to be mounted within on the ceiling of roof, substitutes existing traditional grid lamp.But such plate shape LED illuminating lamp problem has: the LGP cost is high, the illuminating lamp cost is also just high; The LGP light transmission efficiency is limited, thereby causes the light efficiency of illuminating lamp to descend, and the LED chip concentrated setting is at the side of plate shape, and the LED chip heat dissipation problem is serious.
Summary of the invention
The purpose of this utility model is to propose a kind of solid-state lighting lamp, and existing slab structure, can effectively reduce dazzle again, and the structure that takes full advantage of light fixture effectively solves heat dissipation problem as fin, can reduce significantly again the cost cost of light fixture.
The technical solution of the utility model is: on same metallic plate, make and have four Lamp cups at least through punching stretch, form a Lamp cup metallic plate, edge, border at the Lamp cup metallic plate is provided with side edgefold, this side edgefold and Lamp cup metallic plate are that same sheet of metal board processes, each Lamp cup is furnished with solid state light emitter, the power of single solid state light emitter is not more than 8w, solid state light emitter is furnished with heat-conducting plate or heat conduction core, this heat-conducting plate or heat conduction core and Lamp cup are provided with direct or indirect transmission of heat by contact face, Lamp cup metallic plate as lamp distribution and structural member is utilized into fin, the heat that solid state light emitter produces has at least half to pass to Lamp cup (Lamp cup metallic plate) to shed.
Reduce luminous flux density, solve glare problem, have in the technical solution of the utility model: 1, before Lamp cup, be provided with the front diffuser that has adopted diffusing structure or diffusion material; 2, the light sent from solid state light emitter has the reflective surface shone in Lamp cup over half, reflect Lamp cup (light fixture), it is enough large that the reflective area in Lamp cup is wanted again, and pharosage just can effectively reduce, glare problem is also just solved, and three kinds of following schemes are specifically arranged:
Scheme one, be provided with light-distribution lens before solid state light emitter, the light sent from solid state light emitter, after light-distribution lens, has on the reflective surface shone in Lamp cup over half, then towards Lamp cup (light fixture) external reflectance.
Scheme two, in solid state light emitter the place ahead, be provided with the wick reflector, this wick reflector reflexes to the light sent from solid state light emitter over half on reflective surface in Lamp cup, then towards the Lamp cup external reflectance.
Be provided with wick cover and wick reflector before scheme three, solid state light emitter, the wick cover is provided with towards the sidewall of the reflective surface in Lamp cup, and this sidewall has adopted diffusing structure or diffusion material.
The solid state light emitter of the utility model illuminating lamp is divided into several a plurality of, and is furnished with separately Lamp cup, and such structure is conducive to the heat radiation of solid state light emitter and reduces the pharosage (reduction dazzle) of light fixture.Lamp cup quantity is many, single Lamp cup size reduction, the stretch process distortion of Lamp cup reduces, before the reflecting surface in Lamp cup is processed and just can be arranged on stretch process, the sheet metal that can directly adopt existing reflecting surface to process is manufactured the Lamp cup metallic plate, can cut down finished cost like this.But Lamp cup quantity is too much, disadvantageous aspect has, and solid state light emitter quantity is too much, and the cost that solid state light emitter is every watt increases, and the assembly work amount of light source increases.
Number in a plurality of even illuminating lamps all Lamp cup all at same metallic plate through there being punching stretch to make, simple for structure, production efficiency is high, the processing and manufacturing cost is low.Processing cost is effectively reduced, thereby reduces the just further rising of meaning of material usage cost, adopts thinner metal material, can reduce the material usage cost, and disadvantageous aspect has: structural strength reduces and the disadvantageous factor of heat conduction.The Lamp cup of the many projections of number forms reinforcing rib structure, has improved the structural strength of metallic plate, at the edge, border of Lamp cup metallic plate, is provided with side edgefold, structural strength further improves, this side edgefold directly forms from the sheet metal bending of Lamp cup metallic plate, and processing is simple, and intensity is higher; About heat conduction aspect, detailed analysis is below arranged.
Adopt the fin efficiency in " thermal conduction study " to analyze, the Lamp cup metallic plate is during as fin, sheet metal thickness and Lamp cup size (power that the relates to solid state light emitter) impact on heat radiation, choose rational sheet metal thickness (relating to the cost of raw material) and Lamp cup size (power that relates to solid state light emitter).According to " thermal conduction study ", fin efficiency is defined as: the ratio of actual (such as the thermal conductivity factor of aluminium is roughly 200W/mk) heat dissipation capacity heat dissipation capacity during for infinity (desirable Heat Conduction Material) with thermal conductivity factor.
Metal aluminium thermal conductivity factor is high, lightweight, is Lamp cup metallic plate preferred material.According to experimental data and theory and empirical analysis, if only rely on the Lamp cup metallic plate, be fin, when the Lamp cup metallic plate adopts aluminium (thermal conductivity factor is 200W/mk), the area of the Lamp cup metallic plate that the solid state light emitter of 8w will take will reach 15 * 15cm
