Abstract
The invention discloses a portable light heating device. The portable light heating device comprises a light source and a reflector cup, wherein the light radiation power of the light source is greater than or equal to 100 mw. Light emitted from the light source is focused by the reflector cup and forms a focus point for heating an object. The portable light heating device is high in heating speed, light and convenient to carry, capable of saving energy and environmentally friendly.
Description
Technical field
The present invention relates to heating technique, particularly relate to a kind of portable optical heating device.
Background technology
In the prior art, existing firing equipment normally heats with electric energy, gas energy, it is higher to there is electric energy power in traditional electric energy heating, comparatively power consumption, shortcoming energy-conservation not, utilizes combustion gas energy sources for heating, rely on non-renewable energy resources, be a kind of waste to resource, also there is gas leakage, the danger of contaminated environment.And existing smooth heating technique is generally used on solar facilities instrument, volume is large, heavy, and heat by collecting solar energy, the temperature after its heating is generally no more than 100 degrees Celsius, and object is lighted by the ignition point that cannot reach object.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of portable optical heating device, and the light sent by light source is focused on by reflector and forms the focus point heated object, and not only firing rate is fast, and energy-conserving and environment-protective.
For solving the problems of the technologies described above, the present invention proposes a kind of portable optical heating device, comprising light source and reflector that optical radiation power is greater than or equal to 100mw, the light that described light source sends is focused on by reflector and forms the focus point heated object.
Further, also comprise lens, the light that described light source sends is successively by focusing on the focus point being formed and heat object after reflector and lens.
Further, described light source is LED or LD lamp.
Further, described LED or LD lamp are provided with change-over circuit, and optical radiation power LED or LD lamp being sent by change-over circuit is greater than or equal to 100mw.
Further, the diameter of described focus point is less than or equal to 5mm.
Further, described reflector is ellipsoidal reflective cup.
Further, described reflector is plastic filming or metallic reflection cup, ceramic light-reflecting cup.
Further, described lens are Fresnel Lenses.
Technique scheme at least has following beneficial effect: the present invention adopts the light sent by light source focused on by reflector and form the focus point heated object, and not only firing rate is fast, and energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the portable optical heating device of the present invention.
Fig. 2 is the lensed structural representation of the present invention's portable optical heating device band.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, the portable optical heating device of the embodiment of the present invention comprises light source 1, the reflector 2 that optical radiation power is greater than or equal to 100mw, wherein, light source 1 is LED, also can be LD lamp, and reflector 2 is ellipsoidal reflective cup 2, increase operation rate to maximize, the light sent by LED or LD lamp is focused on by ellipsoidal reflective cup 2 and forms the focus point 3 heated object, and not only firing rate is fast, and energy-conserving and environment-protective.
As shown in Figure 2, the focusing effect of the light sent to allow light source 1 is better, or adapt to the installing space of different product, can also install at least one lens 4, the light that LED sends is successively by focusing on the focus point 3 being formed and heat object after reflector 2 and lens 4.Light can more incide on reflector 2 by lens 4, then carries out reflecting focal on focus point 3 by reflector 2.Preferably, adopt the mode of Fresnel Lenses 4, by thinning for lens 4 segment thickness, volume and weight can be reduced; And the diameter of focus point 3 is less than or equal to 5mm, improve the efficiency of heating surface.
As another kind of execution mode, LED or LD lamp are provided with change-over circuit, optical radiation power LED or LD lamp being sent by change-over circuit is greater than or equal to 100mw, improves the efficiency of heating surface.
During use, if adopt radiant power to be the semiconductor light sources of 1w, by reflector 2 by light-ray condensing in the focus point region of 0.5mm, calculated by amount of radiation, we can learn, within 1 second time, the radiant energy value of light source 1 is 0.2J, supposes that the absorptivity of paper is 30%, then the energy value that paper sponges is 0.15J, the specific heat capacity of paper is 1.7 ~ 2.1J/g. DEG C, and the density of paper is 0.7 ~ 1.2g/cm
3, we get maximum to specific heat capacity and density, then in the focus point region of 0.5mm, the quality of paper is m=0.5*0.5*0.12*1.2*10^-3=3*3.6*10E-5g.Therefore, we are according to temperature computation formula, suppose that paper initial temperature is 0 °, then Q=mc (T2-T1), T2=0.15/ (3.6*10E-5*2.1) * 0.88=1746 DEG C.Wherein 0.88 is the reflectivity of reflection chamber in reflector 2, can be implemented in completely in the short time and is lighted by object (such as cigarette), and not only firing rate is fast, and energy-conserving and environment-protective.
The above is the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
