The present disclosure will be further described in detail with reference to the following examples which present explanation the present disclosure and the present disclosure is not limited to the following examples.
As shown in
The lens is located inside the bulb, and the light incident surface of the lens is opposite to an emission direction of a light source of the light-emitting component. The housing includes a convex part opposite to the lamp base, and the lens is arranged on the inner surface of the convex part.
As shown in
Specifically, the lamp also includes a stem 6 on which the bracket is mounted, an end of the bracket is connected with four filaments, and the filaments are mounted parallel to the light incident surface of the lens.
Here, the filament has various forms. In a first form, LED chips on the filament are all located on one side of the filament, that is, on the light-emitting surface, so that the light-emitting surface faces the light incident surface of the lens.
In a second form, the LED chip on the filament is mounted on both sides of the filament, as long as one of the both sides faces the light incident surface of the lens.
In a third form, in other embodiments, if the filament emits light on multiple sides, a position of the light-emitting surface is not considered, and the filament can be directly and parallelly mounted on the light incident surface of the lens.
The luminescent particles can be LED chips directly fixed on a strip-shaped substrate or LED lamp beads fixed on the strip-shaped substrate. The LED lamp bead in this case can be understood as including a granular substrate, an LED chip fixed on the granular substrate, a light-transmitting plastic layer or a colloidal layer covering the chip, and a light source with an exposed conductive end.
In other conceivable embodiments, the filament may adopt a filament-like structure or a strip-like structure composed of an LED chip structure without a substrate and a conductive component.
A thickness of the lens is less than or equal to 100 mm, and a distance between the light-emitting component and the lens is less than or equal to 200 mm.
A design of this structure depends on a size of the bulb lamp commonly used at present. Generally, a distance between the lamp base and a top of the bulb is 30 mm-300 mm in different models, and there are also bulbs with a distance not within this distance range. Taking A60 bulb lamp as an example, in Embodiment 12, the condensing effect of the lamp with a bracket length of 30 mm, 25 mm or 20 mm are further described respectively.
Further, the lens is of a cured light-transmitting colloid, and other light-transmitting plastics can also be used.
In other embodiments, other lens structures may be mounted to the light-transmitting housing, externally or internally.
In this embodiment, colloid is used to fill the bulb lamp, and in other embodiments, a practical finished lens is mounted on the light-transmitting housing.
As shown in
Further, the light-emitting component may have a plurality of light-emitting surfaces, and at least one of the light-emitting surfaces is parallel to the light incident surface of the lens. It is conceivable that at least half of the light-emitting surfaces may be parallel to the light incident surface of the lens.
The lens is located inside the bulb, and the light incident surface of the lens is opposite to an emission direction of a light source of the light-emitting component. That is, the light-emitting surface is arranged towards the light incident surface. The housing includes a convex part opposite to the lamp base, and the lens is arranged on the inner surface of the convex part.
This embodiment is different from Embodiment 1 in that the light-emitting component of Embodiment 1 is with a filament, and a light-emitting component of Embodiment 2 includes a COB panel 3-1 which includes a light-emitting surface 3-10 and a backlight surface. The light-emitting surface is opposite to the light incident surface of the lens, that is, the light-emitting surface faces the light incident surface of the lens, while the COB panel is parallel to the light incident surface of the lens.
In other conceivable embodiments, the COB lamp panel may have an oblique angle with the light incident surface of the lens, and the angle may be 0-60°, providing different light effects. If the angle is greater than 60°, less direct light enters the lens, and its condensing effect is not ideal, but this configuration is not excluded.
As shown in
Further, the light-emitting component may have a plurality of light-emitting surfaces, and at least one of the light-emitting surfaces is parallel to the light incident surface of the lens. It is conceivable that at least half of the light-emitting surfaces may be parallel to the light incident surface of the lens.
The lens is located inside the bulb, and the light incident surface of the lens is opposite to an emission direction of a light source of the light-emitting component. The housing includes a convex part opposite to the lamp base, and the lens is arranged on the inner surface of the convex part.
This embodiment is different from Embodiment 1 in that the light-emitting component of Embodiment 1 is with a filament, and a light-emitting component of Embodiment 3 includes a lamp panel 3-2 made of SMD, which includes at least one LED lamp bead, and the lamp panel made of SMD is parallel to the light incident surface of the lens. The LED lamp bead of this embodiment refers to the lamp bead structure described in Embodiment 1.
A main difference between this embodiment and Embodiment 1 is that the light-emitting component in Embodiment 1 includes four groups of filaments, and this embodiment adopts one filament which has a spiral structure. The whole filament of the spiral structure is suspended and fixed, and two brackets 5 are provided on the stem, one of which is connected to one end of the filament of the spiral structure, and the other of which is connected to the other end of the filament of the spiral structure, thus realizing suspending fixation and electrical connection of the filament. In this embodiment, a base of the filament with the spiral structure is required to adopt a substrate with plastic performance, such as a rigid substrate like an aluminum substrate. After the spiral structure is formed, the filament can be shaped so as not to be moved or shaken. Thus, a stable light source is formed.
A side of the filament of the spiral structure opposite to the light incident face 4-1 of the lens is a light-emitting surface, that is, a side of the filament of the spiral structure provided with LED chips or LED beads is the light-emitting surface, which is arranged toward the light incident face of the lens. It can be seen that the light-emitting surface is not parallel to the light incident surface of the lens, but follows the spiral structure, and an angle between the light-emitting surface and the light incident surface is a continuously changing angle.
In other conceivable embodiments, the filament can be a three-dimensional structure such as a curved or bending structure and the like, and is not limited to the spiral structure. The substrate of the filament can also be a flexible substrate, such as FPC, which is not limited to the rigid substrate, and a fixture can be used to fix the filament in the bulb.
A bulb lamp, as shown in
The second lens includes a light incident surface and a light emission surface which are parallel to each other, and a light incident surface of the first lens is parallel to the second lens. The light source of this embodiment which emits from two groups of lenses has better condensing effect.
The light-emitting component can be any one of Embodiment 1, Embodiment 2, Embodiment 3 or Embodiment 4, and other conceivable light-emitting components with a light-emitting surface being arranged towards the light incident surface of the lens can also be used.
A bulb lamp is disclosed in this embodiment, as shown in
In this embodiment, a convex side of the arc-shaped substrate is provided with a plurality of LED chips or LED lamp beads in series or in parallel or in a mixed series-parallel manner. That is, the convex surface is a light-emitting surface, and the light-emitting surface is mounted toward the light incident surface of the lens.
An angle α is an angle between the light incident surface and the light-emitting surface. It can be considered that the arc-shaped light-emitting surface has a plurality of continuous light-emitting surfaces, each including at least one LED chip or LED lamp bead. Angles between a plurality of continuous light-emitting surfaces and the light incident surface are between 0 and 60°.
In other conceivable embodiments, a concave surface of the arc-shaped substrate has a plurality of LED chips or LED lamp beads in series or in parallel or in a mixed series-parallel manner, that is, the concave surface is a light-emitting surface, and the concave light-emitting surface is mounted toward the light incident surface of the lens.
A bulb lamp is disclosed in this embodiment, as shown in
With regard to the light-emitting component of this embodiment, it can be composed of one filament, two filaments or more, and a light-emitting surface of each filament is arranged toward the light incident surface of the lens. Angles α between these filaments and the light incident surface is 0-60°. Different angles lead to different light effects, and each filament can have a same angle or a different angle, which can be configured according to different needs.
Difference is that the filament is arranged parallel to the light incident surface in
A bulb lamp is disclosed in this embodiment, as shown in
Specifically, one of the lamp panels proximate to the lens is a circular lamp panel with a hollow middle part, and a light-emitting surface of the other lamp panel is just at a opposite position to the hollow part, that is, a light source of the other lamp panel just emits from the hollow part.
In other embodiments, one of the two lamp panels away from the lens may be a hollow annular lamp panel, and the lamp panel proximate to the lens matches a hollow shape of the annular lamp panel; or, a light source away from the lens may be a filament.
A bulb lamp is disclosed in this embodiment, as shown in
In another conceivable embodiment, the third lens is provided on the substrate, and the third lens covers the plurality of LED lamp beads.
Further, the LED lamp beads in this embodiment can be replaced by LED chips, and the LED chips in this paper refer to LED bare chips.
Further, the light-emitting component in this embodiment can be the flexible filament in Embodiment 1 or the COB lamp panel in Embodiment 2.
Difference between this embodiment and other embodiment lies in the structure of the light-emitting component, and structures of other parts of the bulb lamp can be known from Embodiment 1.
A bulb lamp is disclosed in this embodiment. As shown in
A lamp preparation process for preparing the bulb lamps disclosed in Embodiments 1 to 10 is disclosed.

The method specifically includes following steps 1 to 5:
Step 1: filling colloid into the bulb, in which mass or volume of the colloid is prepared according to a preset lens thickness;
Step 2: vacuumizing the bulb after the bulb is filled with the colloid, and standing for the colloid to solidify;
Step 3: spot welding to fix the light-emitting component on the bracket:
Step 4: sealing the bulb, namely sealing the bracket with the light source fixed with the bulb;
Step 5: performing an assemble to electrically connect the power supply component with the electric lead-out wire on the bracket and electrically connect the power supply component with the lamp base if there is a power supply component; or to connect the electrical lead-out wire on the bracket directly with the lamp base if there is no power supply component.
A method for adjusting a light emitting angle of a bulb lamp, for adjusting the light emitting angle of the lamps described in Embodiments 1 to 10 and adjusting a position of a light-emitting component inside the bulb lamp, which specifically includes adjusting a distance between the light-emitting component and a lens. In the lamp of this embodiment, an illumination angle of light emitted by the light-emitting component after passing through the lens, that is a average beam angle (50%), is less than 120 degrees.
As shown in
Taking the A60 bulb lamp and the light-emitting component disclosed in Embodiment 1 as an example, light distribution curves are shown in
C indicates an angle of the horizontal plane:

When light distributions in C0 and C180° sections of the lamp is symmetrical, and light distributions in C90° and C270° sections is symmetrical, such a light distribution curve is called symmetrical light distribution.
Further, referring to the light distribution curve in
Further, with the light-emitting components disclosed in Embodiments 1-10, different condensing effects can be realized after emitted light passes through the lens. On this basis, there are various possibilities in aesthetic design and condensing effect design of the bulb lamp.
