Description
Technical field
Technical field of LED illumination is the utility model is related to, particularly relates to a kind of big efficient low light attenuation LED light of lighting angle
Source component.
Background technology
To make in LED lighting process, luminous energy can obtain maximum utilization, be carried out once generally when lamp bead encapsulates
After optical design, also the light of lamp bead need to be made to focus on illumination region, or expand illumination in the outer progress secondary optical design of encapsulation
Angle.The secondary optical design of existing LED, completed more using optical lens, however, the heat resistance of optical lens compared with
Difference, worked long hours in LED, part electric energy is converted into after a large amount of heat energy discharge, the high temperature occurred often along with summer
Environment, easily make optical lens that self-destruction phenomenon occur, so as to influence the service life of LED, and the course of work, lamp bead is by high temperature ring
Border influences, and it is serious to also result in lamp bead light decay.
The content of the invention
The purpose of this utility model is to provide a kind of big efficient low light attenuation LED light source component of lighting angle.
Realizing the technical scheme of the utility model purpose is, a kind of big efficient low light attenuation LED light source component of lighting angle,
Including housing, light source substrate, some LED lamp beads and some hemispherical lens, each LED lamp bead is respectively arranged on a support,
Each support is mounted on the upper surface of light source substrate, and some hemispherical lens distributions are fixed on a lens slot board, lens
Slot board is stacked and is fixed on light source substrate, and each LED lamp bead corresponds to a hemispherical lens, and each hemispherical lens set
In outside LED lamp bead corresponding thereto, housing is fixedly installed in the lower section of light source substrate, formed with one between housing and light source substrate
Cavity, the dilute layer of a graphite is provided with cavity, the dilute layer of graphite is fixedly installed in the back side of light source substrate, is offered on housing and cavity
The passage of connection.
Further, LED lamp bead is LED eutectic lamp beads.LED lamp bead on the market is mostly LED twin crystal line lamp beads, naked eyes
Be apparent that brilliant line in appearance, technique is slightly coarse, influence it is attractive in appearance, and LED twin crystal line lamp beads generally use welding side
Formula is fixed, and is very easy to cause sealing-off phenomenon, and the utility model is adopted as the LED lamp bead of LED eutectic lamp beads, and outward appearance is more attractive,
And can be fixed by mounting, be not in sealing-off phenomenon, fixed effect is more preferable.
Further, support is EMC supports.EMC supports have high heat-resisting, high integration, are adopted as the branch of EMC supports
Frame, the fixation of LED lamp bead can be made more firm.
Further, on the bottom surface of passage housing.Housing bottom surface is big relative to lateralarea, opens up passage conveniently,
And multiple passages can be opened up, make by the release of dilute layer of graphite heat can Quick diffusing go out.
The big efficient low light attenuation LED light source component of the utility model lighting angle, has by being fixed at the light source substrate back side
Have the dilute layer of graphite of good transfer of heat performance, by LED lamp bead work caused by heat quickly export and distribute, rise dissipate
Heat effect, the heat to shed is flow in air by the passage connected with cavity, in this way, making LED lamp bead and hemispherical lens
Place environment temperature is unlikely to too high, on the one hand, avoids LED lamp bead because of high temperature and light decay is serious, on the other hand, avoids hemispherical
Self-destruction phenomenon occurs for lens, and then improves the service life of hemispherical lens, hemispherical lens is really applied, LED
The light that pearl sends after hemispherical lens, angle can expanded, illumination zone is wider, and LED lamp bead is mounted on light source base
On plate, rather than solid welding, wire bonding process are eliminated, it also avoid sealing-off phenomenon, its operation is simpler.
