Abstract
The utility model discloses an LED (Light Emitting Diode) lighting device, which comprises a semi-cylindrical hollow transparent cover and a semicircular hollow metal shell, wherein the semicircular hollow metal shell is positioned on the opposite face of the transparent cover and is combined with the transparent cover; an accommodating space is formed by the transparent cover and the metal shell; a substrate is fixedly arranged in the accommodating space; at least one LED is arranged on the substrate; and a reflecting sheet is arranged on the inner side of the transparent cover on the part opposite to the substrate and covers a half of the semicircle of the transparent cover from the contact position of the substrate. According to the LED lighting device, the light emitted by the LED can be reflected and concentrated on one side of a normal line of the LED lighting device by using the reflecting sheet with length of 1/4 of the circular arc, so that the lighting effect is improved; and the LED lighting device has a good heat dissipation effect.
Description
Technical field
The utility model relates to the LED lighting device, belongs to the ligthing paraphernalia field.
Background technology
Because LED all has good illuminance compared to traditional incandescent lamp and fluorescent tube, therefore more and more be applied to daily life, yet no matter be that fluorescent tube or LED fluorescent tube, bulb etc. all exist a problem: luminous is the 360 degree scatterings that do not have directionality, that is to say that the light system of ejaculation is evenly distributed in the fluorescent tube both sides; The light that the LED light emitting diode sends for the LED fluorescent tube will be uniformly distributed in the substrate normal both sides that the LED light emitting diode is installed.
When needs are applied to indirect lighting, asymmetric lighting or side lighting place (for example wallboard or backlight) with the LED illumination, the light of normal opposite side will shine the wall limit and can't be utilized, and cause its optics utilization rate to reduce.
Summary of the invention
At the defective of prior art, the utility model discloses a kind of LED lighting device, make light concentrate on LED lighting device normal one side by the light that uses specific reflector plate reflection light emitting diode to send, thereby improved the optics utilization rate.
For achieving the above object, the utility model is achieved through the following technical solutions:
The LED lighting device, comprise semi-cylindrical hollow diffuser, the metal shell of the semicircular hollow that is positioned at the diffuser opposite and is combined with diffuser, diffuser and metal shell have formed spatial accommodation, in the described spatial accommodation substrate is arranged fixedly, at least one LED light emitting diode is installed on the described substrate; In the inboard part relative with substrate of diffuser reflector plate is installed, described reflector plate has begun to cover half of diffuser semicircle certainly with the substrate contacts position.
Pass through said structure, reflector plate is installed in substrate top one side, top, example right side or top, left side, the light that the reflection light emitting diode sends, the light that is radiated on the reflector plate curved surfaces is reflected back, and the light that the LED light emitting diode is sent is the asymmetric irradiation, because reflector plate has covered the circular arc of 90 degree just, therefore (reflector plate is positioned at the top, right side to light, and then reflection ray is exported in the left side by the output of normal one side fully; Reflector plate is positioned at the top, left side, and then reflection ray is exported on the right side), make LED lighting device of the present utility model needing can be widely used in the place of indirect lighting, asymmetric lighting or side lighting.
Wherein, described diffuser is the diffuser of plastics, acryl or glass material.
Wherein, described metal shell is the metallic aluminium housing, has better radiating effect.
Further, described metal shell outer surface is distributed with a plurality of columnar metal things, and metallic aluminium column for example effectively distributes the heat of LED light emitting diode.
Wherein, described reflector plate is sheet metal or plastic sheet, as long as play the effect of reflection ray.
Further, be covered with the reflecting layer on the described reflector plate, described reflecting layer is titanium dioxide layer, has better reflecting effect.
Wherein, described substrate is aluminium base.
By above-mentioned improvement, the light that LED lighting device of the present utility model can make the LED light emitting diode send concentrates on LED lighting device normal one side via reflection, has improved illuminating effect; And LED lighting device radiating effect of the present utility model is good.
Description of drawings
Fig. 1 is the utility model LED illuminator structure schematic diagram.
The specific embodiment
With reference to figure 1, lighting device of the present utility model comprises at least: diffuser 1 is the half round post of hollow; Relative with diffuser 1 and be similarly the semi-cylindrical metal shell 2 of hollow, the two closure (for example groove interlock, bonding etc.) has formed spatial accommodation 21; Fixing (being fastened on diffuser and metal shell junction) has substrate 3 in spatial accommodation 21, at substrate 3 a plurality of LED light emitting diodes 4 is installed; Top-right diffuser inner surface at substrate 3 fixedly has (for example pressing, bonding, applying etc.) reflector plate 5, and reflector plate 5 is the quadrant size, from having begun to cover half of diffuser 1 semicircle with substrate 3 contact positions.
Wherein, be provided with a plurality of columnar metal things 22 at the outer surface of metal shell 2, so that efficiently radiates heat to be provided.
Claims (7)
1.LED lighting device, it is characterized in that comprising semi-cylindrical hollow diffuser, the metal shell of the semicircular hollow that is positioned at the diffuser opposite and is combined with diffuser, diffuser and metal shell have formed spatial accommodation, in the described spatial accommodation substrate is arranged fixedly, at least one LED light emitting diode is installed on the described substrate; In the inboard part relative with substrate of diffuser reflector plate is installed, described reflector plate has begun to cover half of diffuser semicircle certainly with the substrate contacts position.
