Background technology

Along with the continuous development of LED technology, LED not only is used in special lighting fields such as indicator lamp, backlight, and begins to apply to widely various general lightings field as the substitute products of incandescent lamp, electricity-saving lamp.The early stage product that occurs is that the LED lamp is installed in the plastics Lamp cup, and this product is poor owing to radiating effect, the brightness of LED lamp is little and the low inferior reason of light efficiency makes the service life of LED lamp short, be difficult to satisfy significant deficiency such as normal illumination needs.In order to solve the problem of brightness, afterwards the product of Chu Xianing mostly in a Lamp cup a plurality of LED lamps of serial or parallel connection increase brightness, though this technology has solved the problem of illuminance deficiency, must bring bigger caloric value owing to increase light source, dispelled the heat into a great problem of this technical field.In recent years, because the light efficiency of LED lamp is constantly improved, the luminance shortage problem of a LED lamp is eased to a certain extent, but for this main product by heat loss through conduction of LED lamp, problem how to improve radiating effect still is problem anxious to be solved.And present Lamp cup does not have color function; Paster LED also is called SMD LED, and its principle of luminosity is exactly that electric current is passed through compound semiconductor, and by the combination in electronics and hole, superfluous energy will disengage with the form of light, reach luminous effect; But existing paster LED is because rising angle is difficult to limit its application in some field or occasion greater than 160 degree, and its lighting angle still is difficult to be equal to traditional incandescent lamp and electricity-saving lamp.

Summary of the invention

At the problem that above prior art exists, the purpose of this utility model provides a kind of paster LED Lamp cup of adjustable rising angle energy-saving and good heat dissipation effect, applicable to the illumination in places such as restaurant, meeting room, show room, indoor sentiment decoration.

The purpose of this utility model is to realize like this, the paster LED Lamp cup of described a kind of adjustable rising angle, comprise cup and lamp holder, the cup rear end connects lamp holder, its design feature is to be provided with aluminium base in the described cup, aluminium base is provided with a plurality of paster LEDs, be connected with the little aluminium base of bending at aluminium base, the little aluminium base of bending is provided with paster LED, form angle between the little aluminium base of bending and the aluminium base, be connected with an end of heat pipe below the aluminium base, the other end of heat pipe is connected on the lamp holder, and external power is through audio-switch, lamp holder, temperature controller, be connected with paster LED behind the LED light-emitting diodes pipe driving chip.

The purpose of this utility model also can be achieved through the following technical solutions, the paster LED Lamp cup of described a kind of adjustable rising angle, and its characteristics are that the outer surface of described aluminium base and heat pipe scribbles nanometer titanium dioxide coating.

The beneficial effects of the utility model are: the utility model is owing to adopt colored paster LED as the LED luminescence unit, as seven color paster LEDs such as white, redness, green, blueness, yellow, each paster LED is connected with LED light-emitting diodes pipe driving chip, LED light-emitting diodes pipe driving chip adopts isolated constant current electric drive chip, constant current electric drive chip adopts U.S.'s import constant current electric drive chip, the outer surface of cup is provided with heat pipe, the paster LED heat is transmitted to heat pipe through aluminium base, heat pipe sheds heat, improves radiating effect; And be provided with temperature controller at aluminium base, make it to be unlikely to overheated and damage with protection LED lamp.Surface at heat pipe and aluminium base can scribble nanometer titanium dioxide coating, the nano titanium oxide colorless and odorless, nanometer titanium dioxide coating is under illumination, form the hydroxyl free radical of strong oxidizing property on the surface in conjunction with airborne water and oxygen, toxic gas and various infective virus such as the airborne free formaldehyde of potent decomposition, and release of carbon dioxide and water, especially be fit to the bactericidal action of indoor new finishing or situation about buying some new furniture and public occasion such as square commercial center.Illumination applicable to places such as restaurant, meeting room, show room, indoor sentiment decorations.Open and close paster LED by audio-switch, reach more energy-conservation, control is more intelligent.The utility model can effectively enlarge the lighting angle of LED light fixture, eliminates hot spot, dark space that traditional LED light fixture forms owing to non-uniform light, thereby meets or exceeds the illumination effect of conventional incandescent, electricity-saving lamp.When taking into account into the design, effectively remedied the shortcoming that existing LED lamp luminescence angle is little, have the hot spot dark space.
