Background technology

LED illuminator has advantages of that brightness is high, power saving, environmental protection and long service life, and coordinates the light emitting module of LGP with LED illuminator, and the illumination of all kinds of electronic goods of extensive use (as mobile phone, computer) and light fixture is gradually universal.

Shown in Fig. 1, for current light emitting module structure, its light emitting module 10 comprises a LGP 11 and two and is positioned at the LED lamp 12 of leaded light 11 both sides, and this LGP 11 has the reflecting surface 113 of incidence surface 111, an exiting surface 112 and the relative exiting surface 112 of relative two LED lamps 12, these reflecting surface 113 surfaces are provided with multiple micro-structurals, the light source that is positioned at the LED lamp 12 of both sides can enter LGP 11 via two incidence surfaces 111, then reflects by exiting surface 112 outgoing luminous via reflecting surface 113.

Above-mentioned light emitting module is specifically implementing following shortcoming:

One, bright dipping is inhomogeneous: because the light source of LED lamp 12 that is positioned at both sides is in the time being incident to LGP 11, only carry out leaded light by LGP 11, its light source projectile energy can be not same because of haul distance, causes two ends not work compared with bright and middle, emitting brightness uneven phenomenon.

Two, optical efficiency is not good: because LED lamp 12 is scattering light source, and above-mentioned light emitting module 100 there is no any light harvesting design, causes light source all to concentrate and is incident to incidence surface 111, so its light emission rate is still improved.

Three, easily there is disability glare: because LED lamp 12 is scattering light source, cause part light source easily to produce disability glare by both sides outgoing and occur.

Edge this, the inventor is studied improvement meticulously, engages in the experience of this industry, so develop the utility model through for many years.

Utility model content

Therefore the first object of the present utility model is to provide a kind of splendid light emitting module of optically focused, the uniformity and optical efficiency that has.

The second object of the present utility model, is to provide a kind of light emitting module of keeping away the tool leaded light that look disability glare occurs.

Hold, the utility model provides a kind of light emitting module, and it includes:

One LGP, it comprises an exiting surface, two fully reflecting surfaces and two incidence surfaces; This two fully reflecting surface is relative with this exiting surface, and this two complete reflective surface is the configuration of V shape with reversed dip, and this two fully reflecting surfaces surface has multiple micro-structurals, and this two incidence surface is positioned at the left and right sides of this exiting surface and links this exiting surface and this two fully reflecting surface;

Two reflectors, configure respectively LGP both sides relative with two incidence surfaces; And

Two light sources, it configures respectively corresponding to two reflectors, makes two light sources respectively in incident two reflectors, with via two reflectors by two light-source collecting back reflection to two incidence surfaces, then by two incidence surfaces and two fully reflecting surfaces by whole light sources evenly to exiting surface outgoing.

Described light emitting module, wherein, these exiting surface both sides are extended with two extensions; Each reflector comprises a reflecting part and with curved surface and abuts against the base portion of extension, and this reflecting part and this base portion are ∠ shape and link.

Described light emitting module, wherein, multiple micro-structurals are the groove of continuous V-arrangement.

Described light emitting module, wherein, two light sources have two LED illuminators and at least one circuit board.

Hereat, the utility model is compared the real benefit of prior art: the utility model can effectively be concentrated two light sources via two reflectors really, by light source total reflection to LGP, recycle two fully reflecting surfaces and be the configuration of V shape reversed dip, with the repeatedly optical design of total reflection symmetrically and evenly, effectively control radiation direction, tool evenly goes out the advantages such as light effect to improve optical efficiency and height.Therefore the utility model can improve above-mentioned front case problems really, and tangible effect progress is errorless.
