The specific embodiment

The utility model LED Projecting Lamp, volume is little, in light weight, power density is big, except that possessing all characteristics such as energy-conserving and environment-protective of LED itself, also has characteristics such as high light efficiency, high brightness and projection distance are far away, scope is wide.The LED light fixture is substituted the existing public place light fixtures such as employed fluorescent lamp, high-pressure mercury lamp and Metal halogen lamp that throw light on; Enforcement through real case proves; Though initial input is bigger, because the significantly reduction of maintenance cost and electricity cost, the long-term economic benefit is considerable.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

See also Fig. 1 and Fig. 2, Fig. 1 shows the utility model Projecting Lamp structural representation, and Fig. 2 then is the utility model Projecting Lamp blast structural representation.

As main structure body, U-shaped support 7 is fixed on the dual-side of radiator through left plate 11, right plate 2 the utility model Projecting Lamp with radiator 1; The front of radiator is equipped with 2-8 group LED luminescence component I; Power supply 4 is installed in the radiator back; Upper cover plate 17, lower cover 9 are fixed on the upper and lower end face of radiator; The bottom of U-shaped support 7 is provided with installing hole 21.Introduce in detail in the face of each several part down.
