Abstract
The invention provides an LED energy-saving lamp, comprising a casing, a base plate, an LED, light source reflecting bowls, a radiator and a transparent light shade. The invention has the following technical key points: interconnected light source reflecting bowl structures are evenly distributed on the convex side of an arc-shaped heat-conducting base plate; each light source reflecting bowl is provided with an LED on the inner side; and back end part of the LED is connected with the arc-shaped heat conducting base plate; the edges of the light source reflecting bowl structures represent convex honeycomb structures; the radiator is arranged on the concave surface of the arc-shaped heating conducting base plate; the LEDs in the light source reflecting bowls are connected in series. In the invention, as convex honeycomb structure is adopted on the edge which is evenly distributed with interconnected light source reflecting bowl structures, primary light and secondary light which is formed by light source reflecting bowls irradiate evenly on the road or background wall with no generation of any light spot or shadow. The invention is further characterized by simple and reasonable structure, safe and reliable use, low cost, long service life, wide application range and the like.
Description
Technical field
The present invention relates to a kind of lighting technical field, a kind of specifically LED energy-saving lamp.
Background technology
As everyone knows, along with semiconductor technology constantly develops, the LED semiconductor light sources is now paid attention to by government agencies at all levels gradually as energy-conserving light source, and existing a spot of application becomes the third generation lighting source behind lightings such as incandescent lamp, fluorescent lamp aspect street lamp or shot-light illumination.But its characteristic requirement of high-power LED light source must in time be derived the heat that led light source produces during work; Because it is smaller that led light source distributes, need its light source is carried out the secondary optics design, avoid LED street lamp or shot-light luminous too concentrated.Above-mentioned two problems have now become the bottleneck that led light source develops aspect street lamp or shot-light illumination.
Summary of the invention
The purpose of this invention is to provide a kind of LED energy-saving lamp.The present invention is with the uniform irradiation of light source reverberation bowl by alveolate texture, the fundamentally hot spot of Xiao Chuing.
The object of the present invention is achieved like this: it includes housing, substrate, LED, the light source reverberation bowl, radiator, transparent lamp shade is characterized in that: be evenly distributed with the light source reverberation bowl structure of disjunctor on the convex surface of arc heat-conducting substrate, each light source reverberation bowl inboard is provided with a LED, the rearward end of this LED is connected with the arc heat-conducting substrate, and the edge of light source reverberation bowl structure is the alveolate texture of convex surface; Radiator is arranged on the concave surface of arc heat-conducting substrate; LED in the light source reverberation bowl is connected in series mutually.
Housing of the present invention and substrate are designed to integrative-structure as required or divide body structure.
The present invention is in order to increase the radiating effect of radiator relatively, then on radiator, be evenly equipped with fin, side at fin also is distributed with the fin that is used for increasing area of dissipation, and the spacing between the adjacent fin is 8～13 millimeters, so that form circulation air path between adjacent fin.
The present invention as required, the described transparent lamp shade that is arranged on light source reverberation bowl structure front end promptly can be pegged graft with housing seal, can peg graft with radiator again.
The present invention is owing to adopt the alveolate texture of convex surface in the edge of the light source reverberation bowl structure of uniform disjunctor, to making once light and being radiated at equably on road or the wall through the secondary light that the light source reverberation bowl forms, when the present invention is arranged on the high road surface of 8-10 rice, its illumination length is at 50-65 rice, irradiating width is at 12-16 rice, and do not produce any hot spot or shadow.
The present invention is because the spacing between adjacent fin is 8～13 millimeters, side at fin also is distributed with the fin that is used for increasing area of dissipation, make like this to have formed in the fin of spacing and parallel distribution between the fin and be convenient to the mutual convection current of cold and hot air, and the formation circulation air path, thereby guaranteed LED≤45 ℃ use (environment temperature is 29 ℃) down.
The present invention also has simple and reasonable, and is safe and reliable, and cost is low, long service life, characteristics such as range of application is wide.

The present invention is described in further detail by example below in conjunction with accompanying drawing, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
The specific embodiment
Example 1:
Shown in Fig. 1-3, among the figure 1 is the arc heat-conducting substrate, on the convex surface of arc heat-conducting substrate 1, be evenly distributed with the light source reverberation bowl 2 of disjunctor, each light source reverberation bowl inboard is provided with a LED, the rearward end of this LED is connected with the arc heat-conducting substrate, to transmit the heat that is produced under the LED duty, the edge of light source reverberation bowl 2 is the alveolate texture 3 that is convex surface; This radiator 5 is arranged on the concave surface of arc heat-conducting substrate 1 and becomes one structure, and is evenly distributed with the fin 6 that its side is distributed with fin on radiator 5, increases area of dissipation with this, and the preferred distance between the adjacent fin is 10～13 millimeters; Also be connected with an installation pipe support 7 that is fixed on the light pole support arm on the radiator; The mouth place is provided with a slot 8 respectively on two limits of radiator, and this slot 8 is plugged with the arc transparent lamp shade 4 that is located at light source reverberation bowl structure front end, can seal mutually by sealing ring or heat-conducting glue in slot 8.
