Wherein, process through improving reflectivity towards the aluminium base surface of described LED device.
According to one embodiment of present invention, towards the reflectivity on the aluminium base surface of described LED device more than or equal to 40%.
According to one embodiment of present invention, towards the reflectivity on the aluminium base surface of described LED device more than or equal to 60%.
According to one embodiment of present invention, aluminium base surface towards described LED device comprises through improving the reflectivity processing: the aluminium base surface towards described LED device is coated with white paint, aluminium base surface towards described LED device is pasted with reflective sheeting, perhaps towards the process chemical polishing of the aluminium base surface of described LED device.
The present invention also provides the method for a kind of raising with the LED light fixture light transmittance of diffuser, comprising:
LED light fixture with diffuser is provided, and this LED light fixture comprises: aluminium base, be fixed on LED device and diffuser on the described aluminium base, described LED device is positioned at described diffuser;
Process improve reflectivity towards the aluminium base surface of described LED device.
According to one embodiment of present invention, towards the reflectivity on the aluminium base surface of described LED device more than or equal to 40%.
According to one embodiment of present invention, towards the reflectivity on the aluminium base surface of described LED device more than or equal to 60%.
According to one embodiment of present invention, comprise improve the reflectivity processing towards the aluminium base surface of described LED device: apply white paint on the aluminium base surface towards described LED device, pasting reflective sheeting towards the aluminium base surface of described LED device, perhaps to carrying out chemical polishing towards the aluminium base surface of described LED device.
Compared with prior art, the present invention has the following advantages:
In the LED light fixture with diffuser of the embodiment of the invention, process through improving reflectivity towards the aluminium base surface of LED device, thereby reduce light in the loss on aluminium base surface, be conducive to improve luminous flux.
Description of drawings
Fig. 1 is the structural representation with the LED light fixture of diffuser of the embodiment of the invention;
Fig. 2 is the whole lamp transmitance of LED light fixture of the embodiment of the invention and the relation curve of aluminium base reflectivity.
The specific embodiment
In the prior art, the part light that the LED device sends in the LED light fixture is consumed absorption in the reflection of lamp interior, scattering process.In the present embodiment, mainly increase light efficiency by the energy consumption that reduces in the reflection process.
At first consider the simplest situation, when light positive incident medium surface, catoptrical energy can be expressed as with fresnel formula:
Wherein, n
21Be the relative index of refraction of material, R be light can flow reflectivity.
In above formula, R is with n
21Increase increase.And, also can prove by complete fresnel formula, in the situation that non-normal incidence also can obtain conclusions, repeat no more herein.Therefore, can reduce by the reflectivity that increases non-transmissive of lamp interior the loss of energy, to reach the purpose that increases luminous flux.
Because in the LED light fixture, aluminium base has occupied larger area, light can lose portion of energy in exposed aluminium base reflection, so the present embodiment can improve the light efficiency of whole lamp to a certain extent by improving the reflectance factor of aluminium sheet plate.
The invention will be further described below in conjunction with specific embodiments and the drawings, but should not limit protection scope of the present invention with this.
With reference to figure 1, the LED light fixture with diffuser of the present embodiment comprises; Aluminium base 10, LED device 11, diffuser 12.Wherein, LED device 11 and diffuser 12 are fixed on the aluminium base 10, and LED device 11 is positioned at diffuser 12.
With reference to figure 2, the inventor simulates with the variation of aluminium base reflectivity whole lamp transmitance, can be found out by the curve of Fig. 2, and along with the raising of aluminium base reflectivity, whole lamp transmitance also increases.Preferably, the reflectivity of aluminium base is more than or equal to 40%.More preferably, the reflectivity of aluminium base is more than or equal to 60%.
The present embodiment also provides the method for a kind of raising with the LED light fixture light transmittance of diffuser, may further comprise the steps:
LED light fixture with diffuser is provided, and this LED light fixture comprises: aluminium base, be fixed on LED device and diffuser on the described aluminium base, described LED device is positioned at described diffuser;
Process improve reflectivity towards the aluminium base surface of described LED device.
Wherein, after the aluminium base surface improved reflectivity and process, the reflectivity on aluminium base surface was preferably more than and equals 40%, is more preferably more than or equal to 60%.
The mode that improves the aluminium base surface reflectivity has: apply white paint on the aluminium base surface towards described LED device, pasting reflective sheeting towards the aluminium base surface of described LED device, perhaps to carrying out chemical polishing towards the aluminium base surface of described LED device, but be not limited to this.
Although the present invention with preferred embodiment openly as above; but it is not to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification; therefore, protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
