Description
Technical field
The present invention relates to a kind of LED field, particularly a kind of Projecting Lamp of being furnished with high-efficiency radiator LED light source module.
Background technology
LED is a kind of electronic device that can be luminous energy by electric energy conversion with diode characteristic.The LED light fixture has the development prospect be expected most in lighting field, and its outstanding advantages is: luminous efficiency is high, and the monochromaticjty of light is good, spectrum is narrow, without filtering, can directly send coloured visible ray; Its power consumption is few, and in same illuminating effect situation, power consumption is 1/8th of incandescent lamp bulb, 1/2nd of fluorescent tube; Long service life, average life span reaches 100,000 hours; Security reliability is strong, be conducive to environmental protection, and (the cold light source caloric value is low, and non-thermal radiation can safe touch, is convenient to installation and maintenance; The element of the health risks such as not mercurous, sodium, discarded object is recyclable).
LED light source is generally to embed in lighting and uses, only have an appointment in the electric energy of driving light source and 15% be converted into luminous energy, all the other 85% are converted into heat energy, if this part heat energy fails derive in time and distribute, can cause the light source chip temperature significantly to raise, high-temperature causes chip itself and potting resin performance to worsen, 2 ℃ of the every risings of component temperature, and the light fixture reliability just will descend 10%.For example, have experiment to show, when operating temperature is raised to 74 ℃ by 63 ℃, the LED average life span will reduce 3/4.Be that the too high temperature rise of light source chip will cause that luminous efficiency reduces, and causes serious light decay, the lost of life.Therefore " heat radiation " become the important key technology of high-power LED lamp.So the design of good cooling system, the application of good heat sink material is most important.In other words, the design of radiating module has become the key element that ensures the LED quality.
The LED lighting belongs to the end prod of this industrial chain application, although the technology door is lower relatively, except above-mentioned heat dissipation design key technology, its other technologies that need to solve also have following several respects: the performance of (1) light fixture and parameter designing, Industrial Moulding Design, optical design, circuit design, structural design, processing technology, production technology etc.Must consider correlative factor, arbitrary link occurs that deviation all can affect performance and the effect of product.(2) design of light fixture secondary light extraction efficiency.It comprises chip position design, high performance reflector-light cup lampshade design etc.(3) shape-designing.The light fixture profile should be complementary with environment for use, and miniaturization attractive in appearance is comfortable durable.(4) the low pressure constant-current source drives the use of design, high transmission rate mixed light material etc.
The weak point of LED lamp casing radiating module design is mainly manifested in: (1) lamp radiating shell versatility is poor.The radiator of die cast, a kind of design can only be used as a kind of light fixture specification, and remodeling is difficult, die sinking is expensive, totally unfavorable for the exploitation of new product.(2) the light fixture product is difficult to realize seriation.Traditional LED light fixture seriation is more difficult, as: the light fixture of 100W can only be used the lamp outer casing radiator of 100W, and selectivity is strong, and the cost of seriation is very high.(3) heat-delivery surface is limited.In order to guarantee the radiating effect of light fixture, it is heavier that its radiating shell is generally all made.
The principle of design high-efficiency radiator be meet that fundamental strength requires in advance under, obtain maximum heat-delivery surface with minimum quality, to obtaining heat exchange area and the heat transfer effect with the surrounding air maximum.
Summary of the invention
The object of the present invention is to provide a kind of Projecting Lamp of being furnished with high-efficiency radiator LED light source module, LED light source module heat dissipating surface area is large, lightweight.The Projecting Lamp configuration design beautifies, and can form the lamp shape of different patterns, reaches modularization, the seriation development requires of LED light fixture.
In order to achieve the above object, the present invention is achieved by the following technical solutions.
A kind of Projecting Lamp with LED light source module, comprise driving power assembly and at least one group of LED light source module, it is characterized in that: described LED light source module comprises combination of light sources part and radiator body, described combination of light sources part is installed on the front of described radiator body, and described driving power assembly is installed on the back side of radiator body; The radiator that heat radiation tapers that concentric circles distributes, a plurality of that the back side of described radiator body is configured to become; The shell of described Projecting Lamp is connected on described radiator body, and the two is equipped with fixed mount, can make light fixture conversion setting angle, makes light-illuminating in specific direction.
The profile of the good Beautification design of this Projecting Lamp, can meet the different distribution curve fluxs that require.
The characteristics of technique scheme and further the improvement are:
Described combination of light sources part is comprised of the water joint of light source, light-distribution lens, sealing ring, trim ring, screw and sealing wire.Owing to light source having been made to Seal Design (sealing ring+water joint), so, when the assembling light fixture, need not carry out any encapsulation process to light source again.
Described LED light source module is arranged in the shell of described Projecting Lamp, and what the profile of described shell was pressed light fitting shape need to be circle or polygon.
