Abstract
A portable large power LED work lamp comprises a lamp main body, the light source installation surface of the lamp main body is provided with an area for receiving a lens, the lens is sealed and fastened in the area by a lens press cover through a fastener, and a sealing ring is arranged between the lens press cover and the light source installation surface; and the portable large power LED work lamp is characterized in that the light source installation surface and the area are in the same plane, the bottom flat surface of the sealing ring is directly attached on the light source installation surface, and furthermore, the outer periphery of the light source installation surface is provided with surface radiating sheets. In the utility model, the light source installation surface and the area for receiving the lens are arranged in the same plane, and a sealing ring embedded groove is not arranged in the area for receiving the lens on the light source installation surface, therefore, the structure of the lamp main body becomes simpler, and the manufacture and cost are low, furthermore, the surface radiating sheets are on the surface of the light source installation surface, as both the surface radiating sheets and the lamp main body constitute a whole with the light source installation surface, the radiating area is greatly increased and the radiating effect is obvious.
Description
[technical field]
The utility model belongs to a kind of portable high power LED portable lamp.
[background technology]
At present, the great power LED portable lamp is subjected to people's favor day by day with advantages such as its energy-saving and environmental protection, is described as the green illumination product of 21 century, and still, also there are problems in existing great power LED portable lamp, has hindered its fast development.Wherein, production cost height, radiating effect are poor, are the bottleneck problems of LED development always.LED is a kind of photoelectric component, have only 15%～25% electric energy to convert luminous energy in the course of the work, all the other all convert heat energy to, will cause accumulation of heat if can not in time derive heat, cause junction temperature to rise rapidly, and junction temperature is high more, the light decay of LED is just big more, service life is just short more, when junction temperature surpasses maximum allowable temperature (being generally 150 ℃), great power LED can be because of crossing cause thermal damage, therefore, in the design of great power LED portable lamp, radiating effect will directly influence the decay of the aging and LED of electronic devices and components.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of portable high power LED portable lamp, and this portable lamp has that production cost is low, the advantage of good heat dissipation effect compared with similar products.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this portable high power LED portable lamp, comprise a lamp main body, the zone that has admittance lens on the light source installed surface of described lamp main body, lens are fastened in the described zone through the securing member sealing by the lens gland, be provided with sealing ring between lens gland and the described light source installed surface, it is characterized in that: described light source installed surface and described zone are same plane, and sealing ring directly posts on described plane.
During concrete enforcement, the periphery of described light source installed surface is provided with the face fin.
During concrete enforcement, described fin is arranged on the left and right sides of described light source installed surface.
Beneficial effect: compared with prior art, the utility model becomes same plane with the light source installed surface with the zone design of admitting lens, and in the zone of light source installed surface admittance lens the sealing ring caulking groove is not set, therefore, make the structure of lamp main body become simple relatively, cost easy to process is low.Moreover, on the surface of light source installed surface the face fin is set, because the back of the body fin of face fin, lamp main body all constitutes integral body with the light source installed surface, therefore, increased area of dissipation greatly, effect is obvious.
Also in conjunction with the accompanying drawings the utility model is further described below by embodiment.
[description of drawings]
Accompanying drawing is the parts decomposition texture schematic diagram of an embodiment of the utility model.
Among the figure: Battery case 1, lens 2, knob 3, sealing ring 4, handle 5, lens gland 6, support 7, lamp main body 8, lens installed surface 81, face fin 82, securing member 83, switch 9, charging socket 10.
[specific embodiment]
Referring to accompanying drawing.The structure of this portable high power LED portable lamp comprises support 7, and the bottom of support 7 has four splayed feets, and support 7 upwards forms framework, and Battery case 1 is shelved in the framework baseplane.Battery case 1 is provided with switch 9, charging socket 10.Top two side shaft activity orientation lamp main body 8 of Battery case 1, knob 3 can be adjusted the anglec of rotation of lamp main body 8.
Lamp main body 8 comprises lens 2, sealing ring 4, lens gland 6.The zone that has admittance lens 2 on the light source installed surface 81 of lamp main body 8, lens 2 are fastened on the described zone through securing member 83 sealings by lens gland 6.This zone generally is positioned at the middle part of light source installed surface 81.Sealing ring 4 is arranged between lens gland 6 and the described light source installed surface 81.
The utility model compared with prior art mainly contains two innovative points: at first, and the installing structure difference of sealing ring 4.Prior art is that a caulking groove of admitting sealing ring 4 is set in the zone of light source installed surface 81 admittance lens 2, is pressed on the sealing ring 4 by lens gland 6 again, realizes sealing, need increase operation and caulking groove is set, the cost of manufacture height.The utility model will admit the zone design of lens 2 to become and light source installed surface 81 corresponding to same planes, rely on lens gland 6 directly to carry out the sealing and fixing of sealing ring 4, therefore, can omit manufacturing procedure one, help reducing production costs, also can improve the product firmness simultaneously.Secondly, face fin 82 (being commonly called as radiating fin) is set on light source installed surface 81, because face fin 82, and the back of the body fin and the light source installed surface 81 that are arranged on light source installed surface 81 rear portions be connected into integral body, and therefore, radiating effect obviously increases.
The shape of face fin 82, position etc. is set decides, for example: the left and right sides that is arranged on described light source installed surface 81 by feelings.
