Description
Technical field
The utility model relates to the large projection-type illuminating lamp for computer keyboard of a kind of illuminated area, belongs to ligthing paraphernalia technical field.
Background technology
Current illuminating lamp for computer keyboard is generally built in keyboard, there is keyboard price, if the faults such as button damage occur, needs entirety to scrap the problems such as keyboard.
Utility model content
The technical problem that the utility model solves is, provide a kind of computer frame that is built in, usage quantity is few, the projection-type illuminating lamp for computer keyboard that energy-conservation illuminated area is large; Further, the utility model provides the projection-type illuminating lamp for computer keyboard that a kind of illuminated area being easy to dispel the heat is large.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The projection-type illuminating lamp for computer keyboard that a kind of illuminated area is large, it is characterized in that: comprising: the some linear light source being built in computer frame, described linear light source comprises cylinder, one end of described cylinder is closed with convex mirror, the sidewall of described cylinder offers light well, just light source is provided with to described light well in described computer frame outside described cylinder, the reflective mirror for being reflexed to by the light of described light source on described convex mirror is provided with in described cylinder, the opening part of the other end of described cylinder is provided with convex lens, described computer frame is just provided with elliptical aperture to described convex lens, described convex lens are arranged towards keyboard.
Described light source comprises LED.
Described reflective mirror to be arranged at below described light well and to be that 40 ~ 50 degree of angles are arranged with described cylinder inner wall, and the length of described reflective mirror is less than the radius of described cylinder.
The material of described cylinder is lucifuge material.
Described lucifuge material comprises brown or black plastic.
The number of described linear light source is at least 3, is uniformly distributed on the top margin of described computer frame.
Each described linear light source is provided with shift knob on described computer frame, and some described linear light source are also provided with stacked switch button on described computer frame.
The back side of described light source is provided with heat-radiating substrate, and described heat-radiating substrate is connected with heat sink, and described heat sink is embedded on the shell of described computer frame.
The described material stating heat-radiating substrate and heat sink includes copper or aluminium or pottery.
The projection-type illuminating lamp for computer keyboard that a kind of illuminated area that the utility model provides is large, the light of LED is irradiated on reflective mirror by light well, reflective mirror again light reflection on convex mirror, light after convex mirror all in the linear light radiation paralleled with cylinder on convex lens, convex lens come focusing on after the straight line anaclasis paralleled with cylinder to disperse again a bit, make the irradiated area of the light of LED irradiation keyboard large, effectively can reduce the use number of linear light source, there is energy-conservation beneficial effect; Be built in the setting of some linear light source of computer frame, the entirety avoiding the keyboard of traditional built-in illuminating lamp is scrapped, and greatly reduces the requirement to the keyboard that night uses; The setting of heat-radiating substrate and heat sink, is convenient to the heat of LED to shed, and to make in computer frame not easily accumulation of heat, avoids the fire damage of computer, substantially prolongs the service life of computer.
