Compared with the prior art, the LED reflector lamp has the advantages that the reflector lamp casing is provided with the radiating structure, and is an integral piece formed by aluminium alloy through die-casting; and radiating fins in longitudinal divergence are arranged on the outer wall of the reflector lamp casing, a black stoving varnish layer is arranged on the outer surface of the reflector lamp casing, and the radiating performance is better; and an optical grade PMMA lens is mounted above the LED light source, so that discomfort of eyes caused by dazzling light can be effectively avoided.

Description

A kind of LED reflectoscope
Technical field
The utility model relates to a kind of light fixture, particularly designs a kind of LED reflectoscope.
Background technology
Get into the 21 century of resource scarcity, LED is called energy-conservation illuminating product always, compares with incandescent lamp and fluorescent lamp, and it is little that LED has a volume, and the life-span is long, light efficiency is high; Can many multiple combinations, caloric value is low, does not have thermal radiation basically, and power consumption is little; Can low-voltage, the low current starting, long service life, the working time can reach more than 30,000 hours, reaction speed is fast; Can be at high-frequency operation, and environmental protection, shatter-proof, shock-resistantly be difficult for brokenly, recyclable as discarded object, do not pollute.A good LED reflectoscope product must have a good radiator structure, and reasonably lens lighting angle and corresponding anti-dazzle are handled.
Some LED reflectoscope Mechanical Builds is single on the market; Do not possess proprietary heat dissipation metal device; The heat that produces in the time of can not well LED being worked comes out; And the angle that collector lens is selected for use is improper, also with dazzling light, dazzles light and can cause human visual fatigue and influence the human eye perception of light intensity to external world.Though with respect to traditional halogen tungsten reflectoscope; The LED reflectoscope has irreplaceable advantage; But in practical application, how to remove to avoid to dazzle the problem of light and the luminous flux of the least possible loss light source; Improve the radiating effect of whole lamp, strengthen whole lamp and be service life present LED reflectoscope and be badly in need of the problem that will solve.
The utility model content
The utility model technical problem to be solved is to above-mentioned prior art a kind of LED reflectoscope with excellent heat dispersion performance to be provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this LED reflectoscope, comprise lamp housing, and lamp housing is provided with led light source, it is characterized in that: said lamp housing is one to have the shell of radiator structure.
As improvement, said lamp housing is shaped to integral piece by aluminium alloy compression casting, and the outer wall of said lamp housing is provided with the radiating fin that longitudinal divergence distributes, and the outer surface of lamp housing is provided with the stoving black varnish layer.The shell of aluminium die cast has a good conduction to the heat that whole lamp and power supply send; The radiating fin that the longitudinal divergence that the lamp housing outer wall is provided with distributes; The heat that is produced when can be with led light source luminous dissipates to the external world with the mode of free convection and conduction from bottom to top by air and is dissipated in the ambient air; Descend because of the overheated luminous power of led light source that causes with elimination, the colour temperature drift, and then influence the brightness of illumination and the problem in whole lamp life-span; Stoving black varnish technology has tangible booster action to heat radiation; And die casting aluminium is a kind of metal material with high thermal conductivity; In conjunction with heat-resisting, chemical inertness and low frictional properties, the black on surface heat radiation coating has the comprehensive advantage that insulation, other coating such as high temperature resistant can't contend with.
Improve, said led light source is the COB planar light source, is fixed on lamp housing inside through heat-conducting glue again, and COB planar light source luminous flux and colour rendering index are all high a lot of than general led light source, and color reducibility is better.
Improve, optical grade PMMA lens are equipped with in said led light source top again, and optical grade PMMA lens have added anti-UV; Oxidation-resistant material, high temperature resistant, light transmittance is up to more than 95%; And lens outer surface is the design of corase grind sand, and inner surface adopts thin frosting, and the effective like this LED that prevented dazzles the uncomfortable degree that light causes human eye; And light loss is little, and illumination is even, good visual effect; The optically focused angle of PMMA lens is 38 degree, meets traditional halogen tungsten light shape characteristics, is fit to very much be used for substitute traditional halogen tungsten reflectoscope.
Improve, said lamp housing bottom is provided with a lamp holder connector again; This lamp holder connector adopts wear-resisting; Higher and the flame retardant rating of heat distortion temperature reaches the PBT material of UL94 V-0 level and processes; Whole lamp is lighted the heat that is sent for a long time has good ability to bear, can not light the too high working of plastics that causes of the temperature that causes for a long time because of whole lamp and be out of shape.In addition, can spray pitch-dark processing on the plastic surface, this can play positive role to heat radiation.Said lamp holder connector below is provided with the interface of a GU4.0, and lamp holder contact pin material is chosen as brass, and the surface is through Nickel Plating Treatment, and the rust-proofing ability is strong.
Improve, adopt the screw mode to be connected between said lamp holder connector and the said lamp housing, employing screw mode connects; Be prone to assembling; Compare and beat glue fixing, the lock screw has been simplified fit, has accelerated assembling speed; Improved production efficiency, the firm firm while that lets structure become has also been improved safety coefficient accordingly.
Compared with prior art, the advantage of the utility model is: lamp housing has radiator structure, and it is shaped to integral piece by aluminium alloy compression casting, and outer wall is provided with the radiating fin that longitudinal divergence distributes, and outer surface is provided with stoving black varnish layer, good heat dispersion performance; Dress optical grade PMMA lens have effectively prevented to dazzle the discomfort that light causes human eye above led light source.
Description of drawings
Fig. 1 is the structure principle chart of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
LED reflectoscope as shown in Figure 1, it comprises the lamp housing 1 by the aluminium alloy compression casting moulding, lamp housing 1 inner hollow; Lamp housing 1 inside is provided with COB planar light source 2 through heat-conducting glue; COB planar light source 2 is provided with optical grade PMMA lens 3; Said COB planar light source 2 is to be fixed on the lamp housing 1 through screw 4; Lamp housing 1 below is provided with a Plastic lamp socket connector 5, and lamp holder plastic fastening 5 belows also are provided with a GU4.0 standard lamp head contact pin 6, and said lamp holder connector 5 is fixed on the lamp housing 1 through tapping screw 7 with optical grade PMMA lens 3.
In the present embodiment, lamp housing 1 adopts aluminium alloy compression casting to be shaped to integral piece, and lamp housing 1 outer wall is provided with the radiating fin 11 that longitudinal divergence distributes, and lamp housing 1 outer surface has black heat radiation baking vanish layer.The Plastic lamp socket connector adopts wear-resisting, and the PBT material that heat distortion temperature is higher and flame retardant rating is high is processed, and can not cause the working of plastics distortion because of whole light temperature is too high.
