Description

A kind of flashlight with diffuser plate
Technical field
The invention belongs to lighting technical field, relate to a kind of flashlight, particularly a kind of flashlight with diffuser plate.
Background technology
Flashlight is a kind of hand-held electronic illuminations, and a typical flashlight has one via battery powered bulb and focusing mirror, and has for hand-held handle type shell.
Chinese patent CN102865460A discloses a kind of Dimmable electric torch, comprising: tunable light source, for sending the light of different brightness; Drive circuit, first end connects tunable light source, for driving tunable light source; Control circuit, first end connects the second end of drive circuit, for sending driving instruction to drive circuit; And many grades of adjustment buttons, the second end of connection control circuit, for inputting regulating command to control circuit.
In above-mentioned flashlight, regulate can only direct projection for the light of flashlight, uses the same with traditional flashlight; The structure adopted is simplified not enough, and structure is more complicated; The material adopted is general, and service life is short.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose that a kind of structure is simple, the scope of application is wide, the flashlight of the band diffuser plate of long service life.
Object of the present invention realizes by following technical proposal: a kind of flashlight with diffuser plate, comprise cylindrical shell, install respectively and be sealed in lamp adapter assembly and the lamp tail assembly at cylindrical shell two ends, in described cylindrical shell, battery component is installed, described battery component Electricity Federation is to lamp adapter assembly and lamp tail assembly, it is characterized in that, also comprise deflecting plate, described cylindrical shell is made up of copper alloy, described deflecting plate comprises refracting layer, be fitted in reflector layer and the light shield layer of refracting layer two sides respectively, described refracting layer is made up of light transmissive material, described reflector layer and light shield layer are made by light-proof material, described lamp adapter assembly is cylindrical, described light shield layer offers installing hole, the axes normal of described installing hole is in refracting layer, described lamp adapter assembly can insert installing hole and light can refract to the periphery of refracting layer along refracting layer.
Above-mentioned a kind of with in the flashlight of diffuser plate, described lamp tail assembly comprises tail shell, the block that be located on tail shell, be arranged on mounting cover in tail shell and control panel, described mounting cover promotes control panel and is resisted against on tail shell, described control panel protrudes button is installed, described block is resisted against on button, be provided with spring in described mounting cover, the difference Electricity Federation, two ends of described spring is to control panel and battery component.
A kind of with in the flashlight of diffuser plate, described cylindrical shell is tubular above-mentioned, and the outer peripheral face of cylindrical shell is arranged with protective sleeve.
Above-mentioned a kind of with in the flashlight of diffuser plate, described cylindrical shell is made up of copper alloy, count by weight percentage, described copper alloy comprises following component: Cr:0.20-0.60%, Ti:0.05-0.5%, Si:0.05-0.15%, Al:0.05-0.5%, Fe:0.02-0.1%, Ni:0.01-0.2%, Zn:33-36%, surplus is Cu and inevitable impurity.
Cr, Fe, Si limitedly can be solid-solution in copper, can significantly improve the intensity of copper alloy, have solution strengthening effect, when they separate out from solid phase, create dispersion-strengthened effect again.In addition, Fe can crystal grain thinning, the performance of modified alloy.And Zn, Al, Ni solid solubility in copper is very large, especially Ni infinitely dissolves each other, and they and copper form continuous solid solution, has broad monophase field, can significantly improve the mechanical performance of copper alloy, corrosion resisting property.The each element of the present invention's reasonable compatibility on the basis of existing copper alloy, it is made to produce synergy, thus improve the mechanical performance of copper alloy better, especially the intensity, corrosion resistance etc. of contract, and then carry heavy alloyed service life, the cylindrical shell therefore this copper alloy being made the flashlight of band diffuser plate of the present invention can further improve the service life of flashlight.
As preferably, in above-mentioned copper alloy, the mass ratio of described Cr and described Ti: 2.0≤(Cr/Ti)≤8.0, the mass ratio of described Cr and described Si: 2.0≤(Cr/Si)≤10.0.Further preferably, the 78-90% in the total amount of Cr, Ti and Si of containing in described copper alloy separates out.If amount of precipitation is few, then the solid solution capacity in the copper alloy of these alloying elements increases, and brings harmful effect to electric conductivity.In addition, if amount of precipitation is few, then intensity step-down.In order to make electric conductivity, intensity improve, among the total amount needing Cr, Ti and the Si made contained by copper alloy, more than 75% separates out, and is preferably more than 78%.Cr, Ti and Si of separating out can be contained in trickle precipitate, thick precipitate, but from the view point of obtaining above-mentioned required effect, the precipitate that preferably thick precipitate is few, trickle generates manyly, and Cr, Ti and Si of precipitation are preferably contained in trickle precipitate.Therefore, among the total amount of Cr, Ti and Si contained by copper alloy, preferred 78-90% is contained in trickle precipitate and separates out.
As preferably, above-mentioned copper alloy also comprises the P of Sn and/or 0.01-0.05% accounting for copper alloy gross weight 0.01-0.1%.Add tin in containing the copper alloy of 0.05-0.5%Al and can put forward heavy alloyed machinability, the intensity of alloy can also be significantly enhanced, and its plasticity is improved, strengthen the corrosion resistance of alloy, and carry heavy alloyed mar proof, casting fluidity and high-temperature oxidation, the effect in copper alloy of tin and aluminium can be played better.In addition, phosphorus is the deoxidier the most effective in copper alloy, cost is minimum, adds a small amount of phosphorus in copper alloy, the preferred 0.01-0.05%P of the present invention, the mobility of melt in process can be improved, improve the welding performance of copper alloy, corrosion resisting property, and put forward heavy alloyed anti-softening degree.
Above-mentioned a kind of with in the flashlight of diffuser plate, described refracting layer is made up of light transmissive material, described light transmissive material can be grouped into by the one-tenth of following parts by weight: polymethyl methacrylate: 100 parts, nano-LDH: 1-5 part, azodiisobutyronitrile: 1-5 part, flexibilizer: 3-10 part, lubricant: 1-2 part, antioxidant: 0.5-1 part.
Because nano-LDH is nano-scale, particle size is less than visible wavelength, can not affect visible ray through, so add the light transmittance that nano-LDH can improve material under the prerequisite being base material with polymethyl methacrylate (PMMA), if but the number of interpolation nano-LDH is more than 8 parts, along with the increase of addition, light transmittance declines, therefore at refracting layer light transmissive material red interpolation nanometer 1-5 part LDH.In addition, there is hydroxyl in nano-LDH surface, it is the inorganic material that a kind of polarity is strong, and in PMMA strand, there is the stronger ester group of a large amount of polarity, therefore the compatibility of nano-LDH and PMMA is good, makes nano-LDH being uniformly dispersed in PMMA, and then plays its heat stabilizer function, improve the heat endurance of material, and then improve the service life of material.
