According to another embodiment of the present invention, there provides an illumination device. The lighting device has a light transmission housing (812), a base (810), a support base (815), a light bar module (813), and a metal support strip (814). As shown in figure, the metal support strip (814) referred to herein may be the support bar (20) described above (see
The base (810) is connected to the light transmission housing (812) to form an accommodating space (82) together. For example, when the lighting device is a light bulb, the base (810) may be a conventional Edison light head, and the base (810) has two conductive terminals (not shown) on the side and the bottom for connecting to an external power source. Another embodiment is to provide a replaceable or rechargeable battery inside the base (810). If the external power supply is directly connected, the base (810) may be provided with a driving circuit for converting the general indoor power source into a voltage suitable for driving the light emitting diode.
A support base (815) is set on the base (810), and the bottom of the support base (815) extends generally horizontally and is extended to be connect to the bottom of the light transmission housing (812). The platform (816) at the uppermost the support base (815) and the support base (815) is set in the accommodating space (82), and the bottom of the platform (816) is connected to the support base (815). The base (810) and the light transmission housing (812) have a connection boundary line (81) from the outside of the illumination device. The top of the light transmission housing (812) is the first height (821) from the connection boundary line (81) to the top of the light transmission housing (812). The height of the top of the platform (816) to connect boundary line (81) is the second height (822).
In some embodiments, the light bar module (813) is formed by connecting at least two light bars (813a) in series. A support point A is between the at least two series of light bars (813a), and the light bar module (813) has two electrical connection points (818). Take the light bulb as an example, multiple light emitting diode chips may be packaged in series into a light bar (813a). Through the support point A, the light bar (813a) may be further connected in series or in parallel or in both of series and parallel. For the chips of the light-emitting diodes, there is a need for a positive voltage terminal and a negative voltage terminal and may be connected to the voltage supply point of the driving circuit to drive the Light Emitting Diode chip to emit light.
In some embodiments, at least two metal support strips (814) extend outwardly from the platform (816) of the support base (815), respectively, to the one support point A. In some embodiments, the outward direction refers to multiple directions extending away from the support base (815) toward the light transmission housing (812). As shown in figure, the support strip (814) is made of a material of metal, and the metal material for making the metal support strip (814) is a pure metal or a metal alloy such as pure copper, pure aluminum, copper alloy, iron alloy, aluminum alloy, nickel alloy and so on. A vertical height of the metal support strip (814) extending outwardly from the top of the platform (816) is the third height (823) and is greater than the second height (822).
In addition, the at least two metal conductive strips (817) extend outwardly from the support base (815) and is connected to two electrical connection points (818) of the light bar module (813) respectively. Wherein the metal support strip (814), the light bar (813a) and the metal conductive strip (817) form two substantially triangular frame structures. The substantial triangular frame structure mentioned here does not need to be a geometric sense of the triangle. As long as the overall structure of a similar triangle may belong to the side of the real triangular box structure. In addition, the metal support strip (814), the light bar (813a) and the metal conductive strip (817) may be used for a part or all of the sides of the triangular frame structure, respectively, under different designs. In other embodiments, the substantial triangular frame structure is made of polygons having three long sides forming a substantially triangular shape. The present invention is not limited to these examples, and may be considered to be within the scope of the present invention as long as they may achieve a substantially similar effect.
In a design, the support base (815) also has a certain degree of transparency. For example, the support base (815) may be a material of glass. Also, the light transmission housing (812) may be a material of glass. When the support base (815) is the material of glass, the glass bulb may be blown by the production process of the conventional bulb to complete predetermined and a variety of shapes such as incandescent bulb type, water droplet type, candle bulb type, flat head type or multiple predetermined shapes, a pipe may be left in the blow molding process for filling the light transmission housing (812) with the heat dissipation gas. The actual method of operation includes placing the bulb housing (812) in a vacuum environment after the support base (815) is connected to the light transmission housing (812), and then pours various heat dissipation gases through the pipe. In addition, in some embodiments, when the power of the Light Emitting Diodes is small, the heat dissipation gas may not be completely filled and the air for example may be maintained at 3% or more. This may produce a certain degree of adjustment for the effect of light, and may reduce the manufacturing process requirements and cost.
In some embodiments, the top surface of the platform (816) of the support base (815) may be substantially planar and has no raised structure. This does not mean to keep a certain flat, but in essence there is no obvious convex structure. The support of the light bar (813a) is mainly achieved by the metal support strip (814).
In some embodiments, the position of the platform (816) is below the position of the bottom of the light bar (813a). In other words, the light bar module (813) is all held on the platform (816).
In some embodiments, the support base (815) has a top structure (819) and a base (815a). The top structure (819) is joined together with the base (815a) by welding, the metal support strip (814) being in contact with the metal conductive strip (817) extends from the top structure (819). In one embodiment, the top structure (819) is an inverted U-shape, and the base of the base (815a) is substantially circular.
In addition, in some embodiments, in order to adjust the relative position of the light bar module (813) and the light transmission housing (812), the light emitting effect of the surface of the light transmission housing (812) is made more uniform, and the second height (822) is more than 30% of the first height (821), such an arrangement may further optimize the light-emitting effect of the light transmission housing (812).
In some embodiments, at the support point A, the metal support strip (814) connects and supports the light bar module (813) by a snap-in structure (not shown). For example, the metal support strip (814) or the light bar (813a) has a certain degree of bending, buckle, spring, hook, groove, and bump at the support point A may save the complicated engineering of welding, or even if the welding, further strengthen the structure of the stable type.
In some embodiments, the metal support strip (814) and the metal conductive strip (817) are made of the same material.
In some embodiments, the metal support strip (814) forms an assembly unit with the light bar module (813), forms a predetermined shape and is mounted to the light transmission housing (812) in the form of an assembly unit. In this way, the complexity of assembly may be reduced to a certain extent.
In addition, in some embodiments, the light bar (813a) may encapsulate the diode chip on both sides to achieve a higher luminous effect.
In some embodiments, the metal conductive strip (817) has a rigidity that maintains a fixed shape. In some embodiments, the metal support strip (814) has a groove along its length. For example, the metal support strip (814) is elongated and folded at a certain angle along a length to achieve greater rigidity with less material. In some embodiments, the metal support strip (814) is nickel plated.
